开发者 https://www.devze.com 2023-02-09 22:22 出处：网络

I have the following ListView: <asp:ListView ID=\"p开发者_StackOverflowrocedureTicketList\" runat=\"server\" ...

I have the following ListView:

<asp:ListView ID="p开发者_StackOverflowrocedureTicketList" runat="server" ...
     <ItemTemplate> 
          <asp:GridView ID="MyGridView" runa...

How can I access to MyGridView programmatically ?

Use FindControl method.

try the following code snippet.

protected void procedureTicketList_DataBound(object sender, EventArgs e)
      {
          GridView gv= ((GridView)e.Item.FindControl("MyGridView"));
         .
         .
         .

       }

EDIT:

Check the following code snippet.
