the requirement is easy, but I don't know how to do it.
there is a celltable with a column of radio button (or check box but only allow select one row), after user select that row, there is a button and user can click that button to see the detail of that row.
How to do it?
I try to SingleSelectionModel, but I assume the user origin select row 3 radiobutton, then the row3 underlying field is set to true, then when user select the row 5 radiobutton, the row 5 corresponding field is set to true, but I have no method to set the previously row 3 selected field to false.
There is no method to do it automatically. you have to do it yourself by applying a loop. use field updater on that column and get the value on basis of that set the value of other check boxes or radiobuttons. you can get all other elements by this code:
GridReportFields ldp=dataGrid.getVisibleItem(rowNo);
here GridReportFields is my model class. now u have object of corresponding rowNo you can set value of any variable of that object. like:
ldp.setCheckBoxValue(true);
here setCheckBoxValue() is a setter method of model class.

Does ag-grid support separating row selection from checked checkboxes?
My users need to select a row (click on it, or keyboard nav) to see further details about the row. Then they need to check the checkbox (or not) to select the row for later export to Excel.
So for example, they'll click every row to see the further details, but only check some of the checkboxes for later export. Is this supported?
If not, what would be a good approach to implement? Add my own checkboxes to the first column?
You can set suppressRowClickSelection to true when you want checkbox selection, and don't want to also select when the row is clicked. If true, rows won't be selected when clicked.
You can read more about this here - https://www.ag-grid.com/javascript-grid-selection/
You can use ag-Grids selection capabilities for the checkbox selection and then use the onRowClicked prop to do a different select on row click. I'm doing just this (but with onRowDoubleClicked.
You still want to set suppressRowClickSelection to true.
First time creating forms to insert into a database.
I'm trying to create a drop down combo box that lists the entries in the second column...
This is in a seperate table. The issue I'm running into is how do I show what's in the Description column, but when I insert into the form, it's corresponding PMRT_Need value is put in the table.
The database is as such that it HAS to be the PMRT_NEED value unfortunately.
Thanks for your time!
After setting the Row Source to your appropriate table/query:
Set the Bound Column to column 1 (i.e. the PMRT_NEED field)
Set the Column Count to 2
Set the Column Widths to something like 0cm;5cm (adjusting the second width to suit your data) such that the first column isn't displayed to the user.
This ensures that your combo box returns the value of the PMRT_NEED field for the selected item, but only the Description is displayed to the user.
I group my table by 3 attributes, and set page break on every group, and now i want to display that three attribute outside the table. I want to place them on the top of the report, and when i type the expression and i go in run view it's display only the first value, when i go to the next page nothing change
I tried to drag field from table, from data set, and nothing working.
In expression i type
=Fields!My_Field.Value.
Also if some of that three attributes i placed in table it normally displays values, but when i try to move it somewhere it stops displaying.
The issue is that a table is associated with a dataset but a text box is not.
You can reference a field from a text box using the Dataset field ( =Sum(Fields!AMOUNT.Value, "Dataset1") ) but you need to use an aggregate function like First, Last, or SUM.
It sounds like you don't want to use an aggregate since you are grouping by these fields, though.
display the three attribute outside the table
If your trying to display the current grouping in the table at the top of each page, add a new Row in your matrix above your header row and add your group fields there.
I have layout row which contains a dropdown, textfield and two buttons to add and remove rows.
My requirement is i have 10 items in dropdownlist if select one item (say Item1) and click on add row button, a new row will be created as same as first row. Now in the second row dropdownlist items i want to disable the selected item of previous dropdownlist item (Item1).
And i if change the dropdown item of first row to Item3 then automatically in the second row dropdown item it(Item1) should be enabled and vice versa.
How can i do this.
Please help me on this.
Thanks

There are probably more ways to do it, but I would store the selected items in an array and store that in your client model.
Then bind the enabled property of your dropdown template to a formatter function which returns false or true, depending on whether the template item is in the selected array or not
I already have a table - CellTable, with single selection model and i used onSelectionChange to find when row was clicked
Next I added to that column which containes check box
and here comes my problem
if i use single selection model, when i tick one row, other row become unticked
i tried to switch to multiselection model, but in this case, i can't click on row, and onSelectionChanges is executed only when i click on my check box, but i can tick more than one box
is any chance how i can have both - multiselection and clickable row?
regards
Yes it is possible.
But I am suprised that it doesn't work because the default behavior of the MultiSelectionModel should be that the row is selected as soon as you click it. However maybe in the presence of a CheckBoxCell column it is different.
Anyways you have to check following JavaDocs:
Constructor of the CheckboxCell
DefaultSelectionEventManager
