asp.net - add Delete button at last column in gridview -

i adding columns on grid-view dynamically

datatable dt1 = new datatable(); dt1.columns.add("item title", typeof(string)); dt1.columns.add("unit pack", typeof(string)); dt1.columns.add("pack", typeof(string)); gv1.datasource = dt1; gv1.databind(); 

and add delete button automatically by

<asp:gridview id="gv" runat="server">     <columns>         <asp:commandfield showdeletebutton="true" />     </columns> </asp:gridview> 

it shows gridview

| delete | item title | unit pack | pack | 

now want show delete button @ last column like

| item title | unit pack | pack | delete | 

how can this? how create delete button @ last column?

you adding column dynamically thats why need add delete column dynamic. or can add linkbutton in rowdatabound:

protected void gv_rowdatabound(object sender, gridviewroweventargs e) { if (e.row.dataitem != null) {     linkbutton lb = new linkbutton();     lb.commandargument = e.row.cells[3].text;     lb.commandname = "delete";     lb.text = "delete";      e.row.cells[3].controls.add((control)lb); } } 

in rowcommand can write code delete:

protected void gv_rowcommand(object sender, commandeventargs e) { switch (e.commandname.tolower()) {     case "delete": //your code here         break;     default:         break; } }
