Hi Sandeep,
Thank you for your interested in Syncfusion products.
We have analyzed the reported query in our end. you can set the starting position of current cell using the selection start of TextBox. Please refer the below code.
void gridControl1_CurrentCellShowingDropDown(object sender, GridCurrentCellShowingDropDownEventArgs e)
{
GridCurrentCell cc = this.gridControl1.CurrentCell;
GridComboBoxCellRenderer rend = cc.Renderer as GridComboBoxCellRenderer;
rend.TextBox.SelectionStart = 5;
}
Please let me know if you have any concerns.
Regards,
Vinish K.
