How do I get the rowIndex and colIndex from the SelectedRecordsChanging event.
I have tried ...
GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
int rowIndex = cc.RowIndex;
int colIndex = cc.ColIndex;
... but this fails when the the current cell is a ComboBox.
I have also tried ...
string tName = e.Table.TableDescriptor.Name;
GridGroupingControl grid = sender as GridGroupingControl;
GridTableControl tc = grid.GetTableControl(tName);
//Disallow selection from colIndex is greater than 8
bool bSuccess = grid.TableControl.PointToRowCol(grid.PointToClient(MousePosition), out row, out col);
if (bSuccess && col > 8){
e.Cancel = true;
return;
}
//Disallow selection for disabled rows
e.Cancel = !tc.Table.GetTableCellStyle(row, col).Enabled;
but it is always failing, returning -1 for both row and col.
What I am trying to achive is to prevent selection when
1. the row is disabled
2. the current cell column index is greater than 8

Hi James,
Thank you for being patience.
A simple way is to handle the QueryCellStyleInfo event and set a Boolean variable for the cell style is enabled. Depending on which the selection of records can be canceled. Please try the following code snippet.
>>>>>>>>>>Code Snippet<<<<<<<<<
bool flag = false;
void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
if (e.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Record)
{
if (e.TableCellIdentity.RowIndex > 7)
e.Style.Enabled = false;
else if (e.TableCellIdentity.ColIndex > 8 || !e.Style.Enabled)
flag = true;
else
flag = false;
}
}
void gridGroupingControl1_SelectedRecordsChanging(object sender, Syncfusion.Grouping.SelectedRecordsChangedEventArgs e)
{
e.Cancel = flag;
}

I would rather stay away from the QueryCellStyleInfo event. I just need to get the column and row index from within this event.

Any update on getting the rowindex and colindex from the SelectionChanging event? I do not want to use the QueryCellStyleInfo event...
