I'm working with Fiori elements, and in the ObjectPage I want to display a table inside a section. For this table I have a column as a boolean type.
Is it possible to manage this column as a checkbox by annotation, or some other way? If so, how?
I am not sure why it should not be possible. Since a checkbox basically has two states, it should be able to handle the boolean variables very well. Care to explain more about what exactly you want to achieve?
When using Fiori Elements currently a boolean value is displayed as text.
Expect you are in edit mode - then a checkbox is rendered.
So, the answer is 'No' for display mode and 'yes' (by default) for edit mode.

I want the rows of nattable to be single-select only.
Now, multi-selection is possible using ctrl or shift. How do I make single-selection possible?
I would be very grateful if you could leave an answer to a question
If you want to support row selection only, you need to configure the RowSelectionModel to set the multipleSelectionAllowed flag to false and set it as SelectionModel to the SelectionLayer.
Have a look at our examples application to get an idea how this can be done.

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
is it possible to configure agGrid grouping so that it behaves like an accordion i.e. only one group can be expanded and when opening new group previously opened is closed?
Not sure if this answers your question, but I am sure this might be the only direction you'll have.
There is a method provided on gridApi - onGroupExpandedOrCollapsed
So I think (again, need to check) that this function would be called as its name suggests, and you can collapse the other rows (whichever is opened) and achieve your functionality.
Be cautious while using this as there is comment given by ag-grid
we don't really want the user calling this if one one rowNode was
expanded, instead they should be calling rowNode.setExpanded(boolean)
- this way we do a 'keepRenderedRows=false' so that the whole grid gets refreshed again - otherwise the row with the rowNodes that were
changed won't get updated, and thus the expand icon in the group cell
won't get 'opened' or 'closed'.
I need to slightly modify a ag-grid row after it has been rendered. In ag-grid, the actual HTML elements are not necessarily persistent, so manually-set styles may fall off.
For one thing, I have to modify the selection checkbox to set its tabindex to -1. This can technically be done in the cellRenderer callback, although it looks quite hacky. (The checkbox can be found at params.eGridCell.children[0].children[0].wrappedElement.)
But I also have to add a CSS class to some rows to highlight them based on external criteria. I haven't found a way to do this at all.
The best solution would seem to be using some sort of after-rendering callback, but to my knowledge no such thing exists.
I found a couple of related questions, but they were both resolved via cellStyle, which would not suffice here:
Row formatting in ag-Grid
How to provide a background color for an entire row in ag grid based on a certain value in a column?
You have not 1 but 3 options:
getRowClass(params):
Callback version of property 'rowClass'. Function should return a string or an array of strings.
getRowStyle(params):
Callback version of property 'rowStyle'. Function should return an object of CSS values.
processRowPostCreate(params):
Allows you to process rows after they are created. So do final adding of custom attributes etc.
In this last one you have the row in params.eRow.

I have a data-grid and three column in it. one column is type of DataGridViewComboBoxCell, three items are in this grid combo box, now i have to invoke selection index changed event to change value according to combo value change in grid.
also help me to make a new event ....
please help...
thanks
I really can't understand your question.
But maybe these informations can help:
A ComboBoxColumn has always two kinds of controls. A presenting one (in most cases a label) which is individually for each row. And a editing one that will be shared for the whole column. So take a look into this documentation and the IDataGridViewEditingControl Interface.
Maybe these will give you a starting point on how to solve your problem.
In the Load event for the form, you need to get the cell that you want to add the handler to and cast it as a regular combo box. You can then add the event handler on SelectedIndexChanged, but it must be done programmatically, and depending on the language you are using.
