Hello Dorababu,

I have created a sample RadGrid web site where I implemented the requested functionality. Please check out the attached application and let me know in case you need further assistance.

Hello Dorababu,

I am not familiar with your specific scenario and the way your grids are related, however, you could get the row being edited on ItemCommand server event and highlight the corresponding parent item in the main grid:
protected void RadGrid2_ItemCommand(object sender, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.EditCommandName)
        {
            string relationFieldKey = (e.Item as GridDataItem)["CustomerID"].Text;
            foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)
            {
                if (dataItem["CustomerID"].Text == relationFieldKey)
                {
                    dataItem.BackColor = System.Drawing.Color.Lime;
                    // or dataItem.Selected=true;
                    Session["itemIndex"] = dataItem.ItemIndex;
                    break;
                }
            }
        }
        else if (e.CommandName == RadGrid.CancelCommandName || e.CommandName == RadGrid.UpdateCommandName
            || e.CommandName == RadGrid.PerformInsertCommandName)
        {
            RadGrid1.MasterTableView.Items[(int)Session["itemIndex"]].BackColor = new System.Drawing.Color();
            // or  RadGrid1.MasterTableView.Items[(int)Session["itemIndex"]].Selected=false;
        }
    }

I hope this will prove helpful.

All the best,
