My grid Cells doesn''t Refresh

[solmaz Bahramian]

hi;
i used a grid control in my application.it has 2 combo box columns.i also have a listbox which has diffrent values.with selecting diffrent items in listbox the combo column should be refresh with new bound values (from a query based on listbox value).but the combo column doesn't refresh with changing listbox values.i was wondering if it is possible to find the best way for refreshing the bound combo box column .Thanks.

Hi Shayesteh,

Thanks for your interest in Syncfusion Products.

You can acheive this by refreshing that row after the selection has been done by handling the CurrentCellCloseDropDown event.

private void gridDataBoundGrid1_CurrentCellCloseDropDown(object sender, Syncfusion.Windows.Forms.PopupClosedEventArgs e)
{
    GridDataBoundGrid grid =  (GridDataBoundGrid)sender;
    GridCurrentCell currentCell =   grid.CurrentCell;

    if(grid.Binder.NameToColIndex("Col1") == currentCell.ColIndex)
    {
       currentCell.ConfirmChanges();
       grid.RefreshRange(GridRangeInfo.Row(currentCell.RowIndex));
    }
}

Please let me know if this helps.

Regards,
Nisha

Hi shayesteh,

This can be achieved by using the CurrentCellShowingDropDown event. In the event, the datasource / cellvalue of the second column can be changed depending on the value selected in the first combobox column.

Refer to this forum thread for more details : Forum_42073

KB article : How do I change the DataSource of one ComboBox cell depending upon the value selected in another ComboBox cell in a GridDataBoundGrid?
