Cancel Selection on Grid Grouping Control

[Ruslan Gasanbekov]

Hi,

I am using grid grouping control.
When the user select a record on the grid, the values of the record are transferred to the related controls.
On second select if the user changed the previous record, I want to cancel the new selection means:
The new record that the user select won't be selected and the previous record will stay selected.
I am using the CurrentRecordContextChanged event.

See the attached file.

How can I do it?

Thanks

Hi Ruslan,

Thank you for your interest in Syncfusion products.

If you want to prevent the selection in GridGroupingControl, then please try using Cancel property in SelectionChanging event to

achieve your requirement.

this.gridGroupingControl1.SelectedRecordsChanging += new 

SelectedRecordsChangedEventHandler(gridGroupingControl1_SelectedRecordsChanging);
void gridGroupingControl1_SelectedRecordsChanging(object sender, SelectedRecordsChangedEventArgs e)
        {
            // try using your conditional statements here
            {
                e.Cancel = true;
            }
        }

Please let me know if you have any queries.

Hi,

I tried to do it,but it doesn't work.

After canceling this event, the cursor on the listbox is moved to the new selected record (which is the current record), and the old selected record is marked (see attachment).

Cancling this event only prevent the SelectedRecordChanged event to occour.

Is there any other way to cancel the user selection?

Hi Ruslan,

Thank you for the update.

Please try using Cancel property in CurrentRecordContextChange when LeaveRecordCalled action called in GridGroupingControl as shown below.

void gridGroupingControl1_CurrentRecordContextChange(object sender, CurrentRecordContextChangeEventArgs e)
        {
            switch (e.Action)
            {
//other codes
                case Syncfusion.Grouping.CurrentRecordAction.LeaveRecordCalled:
                    {
                     //   Try using you conditional statements
		{
	                            e.Cancel = true;
		}
                    }
                    break;
            }
        }

Please let me know if you have any queries.

Hi,

I tried to cancel only the LeaveRecordCalled action but it doesn't work - it doesn't cancel the selection of the new row.

Do you have a nother solution.

Thanks.

Hi Ruslan,

Thank you for the update.

Please try using CurrentRecordContextChange and SelectionChanging events in GridGroupingControl to achieve your requirement. Because SelectionChanging event is used to prevent the selection in GridGroupingControl and CurrentRecordContextChange is used to prevent the current record move in GridGroupingControl.

Please let me know if you have any queries.
