Answer 1

de PostBackUrl du ImageButton Il devrait être comme ...

PostBackUrl='<%# Eval("SystemEmailID", "Edit_SyatemEmails.aspx?id={0}" 
+ "&blogentry=" + Request.QueryString["edit"]) %>' 

Answer 2

Je vous suggère de le faire dans le code derrière. En GridView événement RowCreated:

protected void GridView_OnRowCreated(Object sender, GridViewRowEventArgs e) 
{ 
    if(e.Row.RowType == DataControlRowType.DataRow) 
    { 
     (e.Row.FindControl("ibtnEdit") as ImageButton). PostBackUrl = "~/Edit_SyatemEmails.aspx?blogentry=edit&id=" + DataBinder.Eval(e.Row.DataItem, "SystemEmailID")) 
    } 
}
