I am trying select single row of sap.ui.table with checkbox.
There are 2 modes for this table
Multi
Single
In multi selection mode there are checkboxes for each row and multiple rows can be selected - but I want only a single row to be selected
In single selection mode, it allows only a row to be selected - but there are no check boxes.
How to achieve a table with checkboxes with only one selectable row?
It is possible with sap.m.table, but my requirement is to make it work with sap.ui.table.
Why I wouldn't recommend doing this:
Checkboxes (selectionMode="MultiToggle") are usually used to signal the user that he's able to select no, one or more options, while radio buttons (selectionMode="Single") tell the user that he's only able to choose one option.
See: material.io, nngroup, uxplanet-radio, uxplanet-checkbox
In your case, I'd recommend using the selectionMode="Single" and either set the selectionBehavior attribute to Row, RowOnly or RowSelector (SelectionBehaviour).
As #jasbir pointed out, you could use the rowSelectionChange event in order to invoke a function that grabs the index (getSelectedIndex) of the row that was just selected. You can then call the setSelectedIndex function on the sap.ui.table.Table and pass it the grabbed index. This will remove previously selected rows and set the currently selected row as selected.
<Table id="yourTableId"
selectionMode="MultiToggle"
rowSelectionChange="onSelectionChange">
</Table>
And in the controller.
onSelectionChange: function(oEvent) {
var oYourTable = this.getView().byId("yourTableId"),
iSelectedIndex = oEvent.getSource().getSelectedIndex();
oYourTable.setSelectedIndex(iSelectedIndex);
}
Note: Since the setSelectedIndex function triggers a rowSelectionChange the above function gets triggered twice (another indicator that this solution isn't intended behaviour).
Check the SAP Fiori Guidelines for the sap.ui.table.Table for further information.
You can use rowSelectionChange event whenever a selection is changed you can unselect other rows and keep the selected one.
Hope this helps

Im using Ag-grid to control my table, but i want in my group that stores a list of rows instead of having to make the row group expand in 2 clicks, i want to be on 1 click.
If i click on the icon arrow it works, but if i click on the title row it only opens on 2 clicks.
I already tried to find in the documentation any information about it, but cant find nothing.
Here is a example from the documentation.
https://ag-grid.com/javascript-grid-tree/index.php
example image:
We are now recommended not to use the onGroupExpandedOrCollapsed, so this should now be...
This will also update the icons and animate the rows, which onGroupExpandedOrCollapsed won't.
onRowClicked(params) {
params.node.setExpanded(!params.node.expanded);
}
This will toggle the expansion, use params.node.setExpanded(true) if you want the rows to just stay open.
You can listen to events on either a row or cell clicked, and expand nodes accordingly.
For example to expand a row based on a click you could do the following:
onRowClicked: (params) => {
// update the node to be expanded
params.node.expanded = true;
// tell the grid to redraw based on state of nodes expanded state
gridOptions.api.onGroupExpandedOrCollapsed(params.rowIndex)
}
This should be in the documentation - I'll update it to reflect this information.
In the column definition, you can use the onCellClicked(params) function to tell it to do something when the cell is clicked. I tried looking for an expand function, but I could only find expandAll() which I don't think you will want. So what I would do is just use jquery or simple DOM selection to click on the expand icon inside of that cell.
this one works
onRowClicked(params) {
params.context.setExpand.onExpandClicked(params.rowIndex, params.node.rowHeight);
}
I have a dataPointGrid and I want to check if a record from it is being selected (mouse clicked on)
Data point grid above. I want to check if a folder (record) is being selected.
Is there a method that does this?
Add ListGrid#addSelectionChangedHandler() on list grid that is called when (row-based) selection changes within this grid. Note this method fires for each record for which selection is modified - so when a user clicks inside a grid this method will typically fire twice (once for the old record being deselected, and once for the new record being selected).
Look at the ListGrid#setSelectionType() as well that defines a listGrid's clickable-selection behavior (MULTIPLE, SINGLE, SIMPLE or NONE)
I want to be able to specify what column triggers the data-toggle event so I can have other columns respond to a different event with out toggling the data.
Here's a plunk that will show what I'm seeing: http://plnkr.co/edit/wqyuuqNfb6qxXBWyHoRo
All columns in a row except the first and last will show a modal dialog when clicked. When the screen is shrunk and the data is collapsed, the toggle icon is displayed on the first column. When you click this icon, the data is toggled as expected. The problem I have is when you click the first name, the data is toggled and then the modal is shown. Is there a way to restrict the toggle event to just the column that is specified?
I found an solution. Just add a trigger to collapse the expanded data as below.
$("table").on("click","td:not(.footable-first-column)",function(e){
var row=$( this ).parent();
$(row).trigger('footable_toggle_row');
$(".modal.fade").modal("show");
return false;
});
Please find the solution in this plunk: http://plnkr.co/edit/QRQyhvvSOmz5oDlR0Cph?p=preview
There was an update to https://github.com/bradvin/FooTable/issues/189#issuecomment-44100073.
I was using the answer by #Duli, but I think this works better.(I will keep his answer as the one I accepted)
When I initialize the table I add an option to change the toggleSelector and that causes the row to only toggle when the icon is selected and not the row.
$('.footable').footable({
toggleSelector: " > tbody > tr > td > span.footable-toggle"
});
i am trying to create a footer component in CQ5, where i have 4 columns & all are autherable.
But we have to make no of columns autherable too i.e based on a value selected form a dropdown we have to open those many tabs for authoring those many columns only.
i have created a dropdown and have a maximum range of 6 columns. i know that i have to configure a listener for this purpose but don't know how . Requirement is like if i select 3 from the drop down then 3 tabs should come to author 3 columns
pls help me , i am middle of something very important.i need the solution very early too as i have to finish the job as soon as possible
I might be late for this by now but in case you still need it:
You need to add a listener node before closing your drop-down element:
<listeners
jcr:primaryType="nt:unstructured"
loadcontent="function(box){ //here you also need to handle the hide/unhide when the panel loads for the first time. Use this.getValue() to retrive the intial value }"
selectionchanged="function(box, value) {
for(var c=1;c<=value;c++){
this.findParentByType('tabpanel').unhideTabStripItem("tab"+c); // You need to handle the opposite with hideTabStripItem("tab"+c);
}
}"/>
Then on both "loadcontent" and "selectionchange" (these are events on your drop-down) grab the current selected value and use it to hide/unhide the tabs. In this case the tabs would be named "tab1", "tab2", etc, make sure you get the names right.
The ExtJS in the events is finding the "tabpanel" container for the whole dialog, and then hiding/unhiding based on name. You could also set to enable/disable using the methods ".enable()" and ".setDisabled(true)". Just make sure you get the reference to the tab first if you want to do this (something like ".getComponent(tabName).enable()").
I didn't test this specific code, I couldn't find my actual example from my code base but this should take you in the right direction.
I want to add a special selection model to the celltable. Basically the function i want to have is to select a row on the table which is located on left side, a corresponding form will pop up on the right side.
I know so many people will use the singleSelectionModel with SelectionChangeHandler.
But there is problem with this method.
For example, if I select row 1 on the table. the form pop up. I close the form by clicking the close-button. Later then, I select the row 1 again, the event is not fired, because it is SelectionChangeHandler. I have to select other row before doing this. This is no good.
So I think there are a few ways to do this:
Make the row deselected right after I select the row.
Use click handler to fire the event ( to pop up the form)
Use other selection model with other selection handler to do this. (I have no ideas about this though)
So my questions are,
Does anyone know what kind of other selection handler I can use for this.
If I use the click handler on celltable, will there be any problem?
I just want to learn more about this. So any ideas will be welcome.
Thanks a lot.
Best Regards.
Use NoSelectionModel. It won't update the table view after the row is selected. That is, even if the same row is selected, the change event is fired.
//Here 'Contact' is the datatype of the record
final NoSelectionModel<Contact> selModel = new NoSelectionModel<Contact>();
selModel.addSelectionChangeHandler(new Handler() {
#Override
public void onSelectionChange(SelectionChangeEvent event) {
Contact clickedObject = selModel.getLastSelectedObject();
GWT.log("Selected " + clickedObject.name);
}
});
table.setSelectionModel(selModel);
I have using cell table in my each project. The better way to just deselect row manually as u mention. and make change css such as selected cell table's row look not changed after selection.
