The grid view fired event row editing which wasn't handled.

See more:

C#3.5

I have gridview as follows

ID Name Season Actions

14756 Test1 2018 Edit Delete
22089 Test2 2018 Edit Delete
33571 Test3 2018 Edit Delete
17912 Test4 2018 Edit Delete


When i click the edit link button in the first row it will redirect to farmermasterpage but when i click edit link button in the third row it does not redirect to farmermasterpage.


Edit code as follows

if (e.CommandName == "Edit")
{
Response.Redirect("~/ivorycoast/farmermaster.aspx?action=edit&farmercode=" + e.CommandArgument.ToString() ,false);
}
 
Gridview source .aspx page code as follows
 
<asp:TemplateField HeaderText="Actions">
<itemtemplate>
<asp:LinkButton ID="lnkEdit" runat="server" ToolTip="Click to edit" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "farmerctscode") %>' CommandName="Edit" OnCommand="onCommand">
| 
<asp:LinkButton ID="lnkDelete" runat="server" ToolTip="Click to edit" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "farmerctscode") %>' CommandName="Delete" OnCommand="onCommand">

when i run the above code shows error as follows

The GridView 'grdFarmerList' fired event RowEditing which wasn't handled.

Note : for response.redirect i added false.

Response.Redirect("~/ivorycoast/farmermaster.aspx?action=edit&farmercode=" + e.CommandArgument.ToString() ,false);

what is the mistake in my above code.
