Hi Ram,
Thank you for you interest in Syncfusion products.
You can validate a cell using by using “CurrentCellValidating” event. Please make use of following code to achieve the behavior.
void gridControl1_CurrentCellValidating(object sender, CancelEventArgs e)
{
if (this.gridControl1.CurrentCell.Renderer is GridTextBoxCellRenderer)
{
GridTextBoxCellRenderer ren = this.gridControl1.CurrentCell.Renderer as GridTextBoxCellRenderer;
if (ren.TextBox.Text == "Software")
e.Cancel = true;
}
}
Here is the sample for your reference.
