I have created a uitable consists of, say, four columns.
colu={{'Sweet' 'Beautiful' 'Caring'},'numeric', 'numeric','numeric'}
dat={1 2 3 []; 4 5 6 []; 7 8 9 []};
A=uitable('outerposition',[0 0 1 1],'ColumnFormat',colu,'Data',dat);
What I wanted to do now is that when the code is run, and I choose 'Sweet' in the pop-up in the first cell, the cell (1,4) displays dat(1,1), or when I choose 'Beautiful' in the second cell in the first column, the cell (2,4) displays dat(2,1). Unlike in a popupmenu outside a uitable, I am not able to use get(popup,"value').
How could I possibly do what I wanted to? Thanks in advance!
You'll have to use the CellEditCallback property, which is a global callback that gets triggered when any cell is edited.
There are no callbacks you can set on individual cells.
A pseudo-code template that should get you started:
function cellEditCallback(hTable, editEvent)
% get changed index
changedIndex = editEvent.Indices;
if changedIndex is a popup-cell:
% check new value
newValue = editEvent.NewData;
% set data in appropriate cell to corresponding value
...
As an aside, the columnFormat in the example does not match the data. It specifies column 1 as a popup-column, while according to your data, it should be column 4.
I also had to change [] to '' to make the popup work and set('ColumnEditable', logical([0,0,0,1])).
See e.g.
http://www.mathworks.de/products/matlab/examples.html?file=/products/demos/shipping/matlab/uitabledemo.html
for a more comprehensive example uitable application.

I'm trying to figure out how to make a GUI with radio buttons that will enable/disable options based on radio button selections. Here's an example of one way I have tried:
fig = uifigure('NumberTitle','off','Name','Option Selection','Position',[750,300,460,520]);
panel1 = uipanel(fig,'Title','Options','Position',[140,80,200,280]);
bg = uibuttongroup(fig,'Position',[140 290 200 51],'SelectionChangedFcn',#bselection);
rb1 = uiradiobutton(bg,'Position',[5 30 100 20],'FontWeight','bold');rb1.Text = 'Option 1';
rb2 = uiradiobutton(bg,'Position',[5 10 100 20],'FontWeight','bold');rb2.Text = 'Option 2';
Opt1_label = uilabel(panel1,'text','Option 1','Position',[5 180 100 20],'FontWeight','bold');
Opt1_field = uieditfield(panel1,'text','Position',[5 160 100 20]);
Opt2_label = uilabel(panel1,'text','Option 2','Position',[5 60 250 20],'FontWeight','bold');
Opt2_field = uitextarea(panel1,'Position',[5 15 190 45]);
function bselection(bg,Opt1_label,Opt1_field,Opt2_label,Opt2_field)
if bg.Buttons(1).Value == 1
Opt1_label.Enable=1;
Opt1_field.Enable=1;
Opt2_label.Enable=0;
Opt2_field.Enable=0;
elseif bg.Buttons(2).Value == 1
Opt1_label.Enable=0;
Opt1_field.Enable=0;
Opt2_label.Enable=1;
Opt2_field.Enable=1;
end
end
The enable/disable if statement works standalone, but I cannot figure out how to get it to work as a callback. Option 2 is not disabled even though option 1 is selected first by default, and if I select another radio button, either nothing changes or I will get an error saying the Enable handle isn't found.
Any ideas are much appreciated
Thanks in advance!
You have configured your function bgselection() to be a callback function for a UI element. Callback functions have two specific rules for the input arguments:
The first argument must be the handle of the object that called the function, and the second must be "eventData" for the callback event. So in your function, the argument Opt1_label is being treated as a eventData variable. Since it does not have the information expected in that variable, there is an error. So to follow this rule, change your function definition to:
function bselection(bg,eventData,Opt1_label,Opt1_field,Opt2_label,Opt2_field)
The second rule is that if you want to have more than the required two input arguments, you need to list them in a cell array when the function is assigned to the object. So in your case, define the uibuttongroup like this:
bg = uibuttongroup(fig,'Position',[140 290 200 51],'SelectionChangedFcn',{#bselection,Opt1_label,Opt1_field,Opt2_label,Opt2_field});
You will have to move the definitions of Opt1_, Opt2_ etc before the bg statement, so that they exist and can be included in the cell array.
You can see the documentation for this here. There are a couple other options for passing arguments, but these are the most common methods.
Also, the eventData has some useful information, such as the label of the button that is selected. Try adding disp(eventData) to the function to see what is included there.
How can I write the expression in order to change background color for each two rows in SSRS?
I need something like that:
I tried expression
=IIF(Fields!Type.Value="2016 Submitted" , "LightBlue",
IIF(Fields!Type.Value="2015 Submitted" , "LightBlue",
Nothing))
But because some months dont have values it looks like this:
If I try this expression I get below:
=IIF(RunningValue(Fields!Count.Value, CountDistinct, Nothing) MOD 2 = 1, "White", "PaleTurquoise")
Dance-Henry I tried your code
=IIF(RowNumber(Nothing) Mod 4 = 1 or RowNumber(Nothing) Mod 4 = 2, "Aqua","White")
and this is what i got:
You can select the row in design pane and press F4 to setup property BackgroundColor as =IIF(RowNumber(Nothing) Mod 4 = 1 or RowNumber(Nothing) Mod 4 = 2, "Aqua","White")
Captures are attached. Do it accordingly.
RESULT is something like this
After going thru the link https://blogs.msdn.microsoft.com/chrishays/2004/08/30/green-bar-matrix/
Tested and it works well for the Green Bar Effect for Matrix. I will show it step by step here as for later reference.
Step 1: Create the Matrix and add one more column under the innermost row grouping in your matrix. (ColorNameTextbox here)
Step 2: Select the textbox of ColorNameTextbox and press F4 to setup BackgroundColor property as =Value shown below.
Step 3: Select the textbox of Matrix cell and press F4 to setup BackgroundColor property as =ReportItems!ColorNameTextbox.Value shown below.
Step 4: Drag the inner grouping header (ColorNameTextbox) to be as narrow as possible.
Step 5: Preview Pane to check the result.
If you could add a hidden color_group column and populate it with a new number at each point you want to change the color (in your case 1,1,2,2,3,3,4,4) then you could use something like the following (which works for varying size groups):
IIF(RunningValue(Fields!color_group.Value, CountDistinct, Nothing) MOD 2 = 1, "White", "PaleTurquoise")
I had a similar problem where I could not come up with alternating rows because my data has Column Groups that were the RowNumber(Nothing) method to fail. Learning from all the other posts here this is how I resolved it in steps.
I added the following code into the report properties, that provides a function to get the row number, each time it is called. The function increments the row count each time it is called. >>Right click space around the report >> Properties >> Code. Alternatively go to Code Properties Window, when the report is selected.
Add the following lines:
Public Row_Sum As Decimal = 0
Public Function Lookup_Sum( ) As integer
Row_Sum = Row_Sum + 1
Return Row_Sum
End Function
I added a new column at the beginning of the rows called No. that would calculate and show the row number.Right click the first column >>Insert Column>>Inside Group-Left.
On the expression for the new report add this line of code. Also take a note of the name of the TextBox that will have the No. Value. It will be needed in the next step. In my case the TextBox is called TextBox6 (Properties Window). >>Right Click Cell>>Expression.
Add the code:
=Code.Lookup_Sum()
I highlighted the entire row and went to the Background property and added the following expression to compute the row number.
Add the code(TextBox6 is the name Textbox name noted above):
=IIF(VAL(ReportItems!Textbox6.Value) MOD 2, "LIGHTBLUE", "WHITE")
I created a listbox and enabled multiple selections. My listbox contain numbers from 1 to 10. When I select 3, 1, and 8, the function always put my selections in alphabetical order (1,3,8). Is there any way I could make it not put my selection in alphabetical order? So if I select 3, 1, and 8 the output of my selection is 3, 1, 8.
Thank you.
For the purpose of this answer I'm assuming you're using matlab-hg2.
From the docs for uicontrol:
'listbox' ... The Value property stores the row indexes of currently selected list box items, and is a vector value when you select multiple items. After any mouse button up event that changes the Value property, MATLAB evaluates the list box's callback routine. To delay action when multiple items can be selected, you can associate a "Done" push button with the list box. Use the callback for that button to evaluate the list box Value property.
From the above we learn that the information on the selected lines is returned in Value. From there, it's a matter of keeping track of what's selected. This can be quite easily done using a persistent variable inside the listbox' Callback as shown in the following example:
function LISTBOX_EXAMPLE
hFig = figure('Units','Pixels','Position', [200 200 100 200],'Menubar','none');
uicontrol(hFig, ...
'Style', 'listbox',...
'Units','Pixels',...
'Position', [20 20 80 150],...
'Max',3,...
'Min',0,...
'String',num2cell(1:10),...
'Callback',#selectionCallback);
function selectionCallback(hObject,~)
persistent previouslyChosenItems
%// Elements were added:
if numel(previouslyChosenItems) < numel(hObject.Value)
previouslyChosenItems = union(previouslyChosenItems,hObject.Value,'stable');
%// Elements were removed:
elseif numel(previouslyChosenItems) > numel(hObject.Value)
previouslyChosenItems = intersect(previouslyChosenItems,hObject.Value,'stable');
%// A different element was selected (single element):
elseif numel(previouslyChosenItems) == numel(hObject.Value) && numel(hObject.Value)==1
previouslyChosenItems = hObject.Value;
end
disp(['Currently selected items (in order): ' num2str(previouslyChosenItems(:)')]);
end
end
Example output:
Currently selected items (in order): 7
Currently selected items (in order): 3
Currently selected items (in order): 3 9
Currently selected items (in order): 3 9 1
Then it's up to you to assign the value of previouslyChosenItems somplace useful.
To generate a ui-table I'm using GUIDE. To insert a popup menu into the ui-table I'm using the following code(for example):
data = {1;2;3,'A';'B';'C'}
set(handles.uitable,'ColumnFormat',{'1','2','3'},'char',data)
Then i will get the same popup menu in every row of the ui-table.
But I want to have different popup menus in different rows of a ui-table, as shown in the picture below.
If I understood correctly, you want to set the 'ColumnEditTable' property of selected columns to true during the creation of your table, and depending of the columnformat you specify you can get popupmenus or checkboxes for example.. Consider this code, which I modified form the doc (look here)
function MyTable
f = figure('Position',[300 300 400 400]);
% Column names and column format
columnname = {'Greeting','Amount','Available','Fixed/Adj'};
columnformat = {{'Hello' 'Hi'},'bank','logical',{'Fixed' 'Adjustable'}}; %// Set the entries of the popup menu in a cell array. When the format is 'logical', the output in the table is a checkbox.
% Define the initial displayed data
d = {'Hi' 456.3457 true 'Fixed';...
'Hello' 510.2342 false 'Adjustable';...
'Hi' 658.2 false 'Fixed';};
% Create the uitable
t = uitable('Data', d,...
'ColumnName', columnname,...
'ColumnFormat', columnformat,...
'ColumnEditable', [true false true true],... %// That's the important line. Entries set to true will allow you to create a popup menu for the whole column.
'RowName',[]);
The table looks like this:
As you can see you can select 'Hi' or 'Hello' in the first columns and either 'Fixed' or 'Adjustable' in the last column.
Hope it gets you started and it's somewhat what you wanted!
The table cell is edit with a simple click, I want it to be edit only on double click. Simple click will select the cell.
I'm use this property of uitable:
set(hTable, 'Data',data,...
'ColumnEditable', edit,...
First you need to set the cell editabiliy to false by default:
set(hTable,'ColumnEditable', [false false ...]); %accordingly your number of columns
and introduce a CellSelectionCallback:
set(hTable,'CellSelectionCallback',#cellSelect);
which calls the following function within the same script
function cellSelect(src,evt)
getstate = get(src,'ColumnEditable'); %gets status of editability
index = evt.Indices; %index of clicked cell
state = [false false ...]; %set all cells to default: not editable
state(index) = ~getstate(index); %except the clicked one, was it
%already false before set it true
set(src,'ColumnEditable', state) %pass property to table
end
and also a CellEditCallback:
set(hTable,'CellEditCallback',#cellEdit);
calling
function cellEdit(src,~)
state = [false false ...];
set(src,'ColumnEditable', state)
end
minimal example
function minimalTable
h = figure('Position',[600 400 402 100],'numbertitle','off','MenuBar','none');
defaultData = {'insert number...' , 'insert number...'};
uitable(h,'Units','normalized','Position',[0 0 1 1],...
'Data', defaultData,...
'ColumnName', [],'RowName',[],...
'ColumnWidth', {200 200},...
'ColumnEditable', [false false],...
'ColumnFormat', {'numeric' , 'numeric'},...
'CellSelectionCallback',#cellSelect);
end
function cellSelect(src,evt)
getstate = get(src,'ColumnEditable');
index = evt.Indices;
state = [false false];
state(index) = ~getstate(index);
set(src,'ColumnEditable', state)
end
function cellEdit(src,~)
state = [false false];
set(src,'ColumnEditable', state)
end
As you figured out this is not always working. Because you have the same issues like I had before with popup menus. It's exactly the same problem: ColumnEditable is just a row vector and not a matrix. I had to deal with the ColumnFormat property, which is also just a row vector. If the double click feature is really important to you, you can consult the following two answers:
Is it possible to prevent an uitable popup menu from popping up? Or: How to get a callback by clicking a cell, returning the row & column index?
How to deselect cells in uitable / how to disable cell selection highlighting?
The threads basically suggest to create a unique uitable for every single row, so that every single row has a unique ColumnEditable property. That's the only solution so far.
I'm afraid there is no simple solution. I can't offer you further help, except the complicated workarounds of the other answers. Or just use the simple one above and live with the little drawbacks.
Although this thread is old but in my opinion still valuable to some users.
I have tested the following with R2010b 32bit.
I have achieved editing only on double click simply by setting
set(hTable,'CellSelectionCallback',#tableCellSelectCB,'ColumnEditable',true)
and defining its function the following
function tableCellSelectCB(~,~)
try
h.jtable.getCellEditor().stopCellEditing();
catch
end
end
where h.jtable refers to the underlying java object of your uitable.
This way, I can select even single and multiple cells, without going into edit mode. On a double click on a single cells lets me edit its contents.
Extension to have individual editable rows
I wanted to have checkboxes in the top row and non-editable (not directly at least) data in the rest of the table. You can easily modify the above:
function tableCellSelectCB(~,evd)
if evd.Indices(1) > 1
try
h.jtable.getCellEditor().stopCellEditing();
catch
end
end
end
