Hi,
Thank you for your interest in SYncfusion Products.
You can handle CurrentCellCloseDropDown for this. Please refer the code:
this.gridControl1.CurrentCellCloseDropDown += new Syncfusion.Windows.Forms.PopupClosedEventHandler(gridControl1_CurrentCellCloseDropDown);
void gridControl1_CurrentCellCloseDropDown(object sender, Syncfusion.Windows.Forms.PopupClosedEventArgs e)
{
//
}
Also please refer the KB article that shows "How do I make the value in one combo box cell determine the drop-down list in another combo box cell? "
Here is the link:
