Hello Sir,

I'm trying to make a Gridview column itself as a hyperlink for regenerating reports for that particular row.

I have been using the below code for the same.

<asp:CommandField ShowSelectButton="True" ButtonType="Link" ShowHeader="True" SelectText="Report" ></asp:CommandField>

in Codebehind

 

 protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        int index = GridView1.SelectedRow.RowIndex;
        clientId = Convert.ToInt32(GridView1.Rows[index].Cells[0].Text);
        string role = obj.Encrypt(Convert.ToString(roleID));
        Response.Redirect("clientreport.aspx?ID=" + role + "&clientId= " + clientId);
    }

Using this I'm able to generate the reports but using my code one new column is getting generated, i want hyperlink to created from where onclick  report should be generated for particular row ID.

Thanks
