On first sight...you are adding attributes to a new instance of the textbox
TextBox ValTextbox = (TextBox)row.Cells[1].FindControl("NameofFormTxt");

not the textboxes in the grid view

Second ValTextbox.Attributes.Add("onblur", "return validateDate(this.id);"); what is this.id here.

Try the below answer. if any problem let us know

Hi Rajesh,

You need to do following:

.aspx.cs file

C#

void CustomersGridView_SelectedIndexChanged(Object sender, EventArgs e)
{
  // Get the currently selected row using the SelectedRow property.
  GridViewRow row = CustomersGridView.SelectedRow;
 
}

.aspx file

XML

<asp:gridview id="CustomersGridView"
       selectedindex="1"
       onselectedindexchanged="CustomersGridView_SelectedIndexChanged"
       runat="server" >
</asp:gridview>

Thanks,
Imdadhusen
