Hello Bharat,

You can access the DeleteButton using its ColumnUniqueName. Check out the following code snippet.

C#:

protected void RadGrid1_ItemDataBound1(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

ImageButton btnDelete = (ImageButton)item["DeleteCommandColumn"].Controls[0]; // accessing Delete Button

if () // your condition

{

btnDelete.Enabled = false;

}

Also refer the following documentation.
Accessing cells and rows

Princy.
