Repeater in Panel

[Mick Walker]

Hi Folks,

I have a situation where I have a repeater within and ASP Panel on my page.
If the repeater contains no items, then I don't need to show the panel,
however if it does then I do.

I tried the following in the page load event:

// Check to see if we have any new messages
if(repMessages.Items.Count == 0)
{
pnlMessages.Visible = false;
}
if(repMessages.Items.Count 0 )
{
pnlMessages.Visible = true;
}
However that didn't work, so I figured that the data must be bound after
the page load event fires.So I then tried:

protected void repMessages_ItemDataBound(object sender,
System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
pnlMessages.Visible = true;
}

Thinking that if an item is being databound, then the Items.Count
property of the repeater must be 0. However that didn't work either.

So my question is, How can I show and hide a panel which contains a
repeater based on the content (or lack of) of the repeater itself?

Kind Regards
Mick

This is the C# language newsgroup. You want to post this in the asp.net
group, as it is really not so much a language question as it is an ASP.NET
framework one.

Just put your code in Repeater1_DataBound instead of Page_Load.
Don't use ItemDataBound, because it will be executed for every item.
Once (after the databinding) is enough.

Repeaters do not have DataBound event.

Correct, though they do have an OnItemDataBound method:

My mistake.

If you use declarative databinding with a SqlDataSourceControl or
AccessDataSourceControl, you may use the OnSelected event on that control.
