Problem handling event in a button inside a Datalist

[ed]

Hello All.

Scenario: I have a web form with a textbox, a button and a datalist (lets
call it datalist1), when the user clicks in the button I add items to the
datalist1 as much as the textbox says. Each item in datalist1 has a label, a
link button and other datalist (datalist2), the label shows the item index,
and above the datalist2 I have a link button intended to add items to the
datalist2. I successfully can add items to the datalist1 when clicking the
button, but when clicking the Add linkbutton nothing happens. I subscribed
the onclick event by getting a reference to the button in the ItemDataBound
event in datalist1.

private void datalist1_ItemDataBound(object sender, DataListItemEventArgs e)
{
LinkButton lnkAdd = (LinkButton)e.Item.FindControl("lnkAdd ");
lnkAdd.Click += new EventHandler(lnk_Click);
}

private void lnkAdd _Click(object sender, EventArgs e)
{
// This never executes…
}

Is this way right to subscribe the event to the "add" button? What can be
the cause of this?

Thank you very much

hi Ed, you can respond to the event in ItemCommand event exposed by the
datalist. All child controls that fire events bubbleup and fired here.

Or you can keep your current code and instead of wiring the event in
ItemDataBound you can wire it declaratively in your linkbutton itself
<asp:linkButton .... onclick="lnkAdd" />

Thank you very much

It worked this way: <asp:linkButton .... onclick="lnkAdd" />
