I have the a ListView
like this
<asp:ListView ID="ListView1" runat="server">
<EmptyDataTemplate>
<asp:Literal ID="Literal1" runat="server" text="some text"/>
</EmptyDataTemplate>
...
</asp:ListView>
In Page_Load()
I have the following:
Literal x = (Literal)ListView1.FindControl("Literal1");
x.Text = "other text";
but x
returns null
. I’d like to change the text of the Literal
control but I don’t have no idea how to do it.
I believe that unless you call the DataBind
method of your ListView
somewhere in code behind, the ListView
will never try to data bind. Then nothing will render and even the Literal
control won’t be created.
In your Page_Load
event try something like:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
//ListView1.DataSource = ...
ListView1.DataBind();
//if you know its empty empty data template is the first parent control
// aka Controls[0]
Control c = ListView1.Controls[0].FindControl("Literal1");
if (c != null)
{
//this will atleast tell you if the control exists or not
}
}
}
