Gridview

I am using asp.net gridview to display my records from list. My gridview will contain boundfields and templatefields. Template fields will have link button in itemtemplate to delete row by firing row_command event. My columns in gridview are to maintain display order in columns based on values set in database. In order to maintain column display order, i cloned gridview and added columns in gridview dynamically. It is working fine. But the problem is i need to add template field that will contain linkbutton in gridview dynamically.
The templatefield code that is to be created in runtime is:

<asp:TemplateField>
    <ItemTemplate>
        <center>
            <asp:LinkButton ID="lnkDelete" runat="server" Text="Delete" CommandName="Delete" CommandArgument='<%#Bind("DrCrGroupNo") %>' />
        </center>
    </ItemTemplate>
</asp:TemplateField>

My code to clone and rebind columns is:

var columnToMove = gridTransactionDetail.Columns.CloneFields();
 gridTransactionDetail.Columns.Clear();

gridTransactionDetail.Columns.Add(listTran);

In order to add template field in runtime, i added a code. My problems is this code is not working, The code i addded is :

public class TemplateHandler : ITemplate
{
void ITemplate.InstantiateIn(Control container)
{
LinkButton lnkDelete = new LinkButton();
lnkDelete.ID = "lnkDeleteThis";
lnkDelete.Text = "HI";
lnkDelete.Click += new EventHandler(Dynamic_Method);
container.Controls.Add(lnkDelete);
}
protected void Dynamic_Method(object sender, EventArgs e)
{
((LinkButton)sender).Text = "Hellooooo";
}
}

On Page_Init method(where clone and rebind columns is done ) as well as page_load, i added code to create gridview dynamically.The code is :

TemplateField TmpCol = new TemplateField();
TmpCol.HeaderText = "Click Me";
gridTransactionDetail.Columns.Add(TmpCol);
TmpCol.ItemTemplate = new TemplateHandler();


I though I will add remaining properties of linkbutton like commandname, commandargument, onclick on RowDataBound event. the code is :

var find =(LinkButton) e.Row.Cells[10].FindControl("lnkDeleteThis");
here, find value is null. As a result, i am not able to add properties and delete row from gridview, How can i do it? any help? thanks in advance.
