Solution 1

C#

<asp:ButtonField ButtonType="Image" ImageUrl="~/Images/pdf.png"  CommandName="pdf_click" ID="imgprint"/>

Code behind

C#

void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
 {
 // If multiple buttons are used in a GridView control, use the
 // CommandName property to determine which button was clicked.
 if(e.CommandName=="pdf_click")
  {
   // Convert the row index stored in the CommandArgument
   // property to an Integer.
   int index = Convert.ToInt32(e.CommandArgument);

   // Retrieve the row that contains the button clicked
   // by the user from the Rows collection.
  ButtonField cf = (ButtonField)e.Row.FindControl("imgprint");
  cf.ImageUrl = "images/something.png";
   // Now you have access to the gridviewrow.
  }
}

Hi,
I tried your code but in the ButtonField property ID (ID="imgprint") is Not available. So it gives me an error like..

Type 'System.Web.UI.WebControls.ButtonField' does not have a public property named 'ID'

And in RowCommand event Row method is not available..
ButtonField cf = (ButtonField)e.Row.FindControl("imgprint");

so it gives a below error..
'System.Web.UI.WebControls.GridViewCommandEventArgs' does not contain a definition for 'Row' and no extension method 'Row' accepting a first argument of type 'System.Web.UI.WebControls.

And Yes i used a ButtonField in Column(one ButtonField for each record) in the Gridview...

Any solutions for these errors??
