how to get the control ID embedded in a repeater?

[Dan]

Hi,

I have a repeater which contains an imagebutton like this:

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="S qlDataSource1">
<ItemTemplate >
<asp:ImageButto n ID="ImageButton 1" runat="server" ImageUrl='<%#
Eval("myfield", "mf\{0}") %>' " runat="server" />
</ItemTemplate>
</asp:Repeater>

I try to get its id in code-behind; i tried this ithout succes:

Dim img As ImageButton
img = Repeater1.FindC ontrol("imagebu tton1")

Thanks
Dan

First of all, you cannot get the individual IDs until the Repeater is
DataBound, so the best place to do what you are doing would probably be in
the ItemDataBound event.

protected void Repeater1_ItemD ataBound(object sender, RepeaterItemEve ntArgs
e)

You would use something like the following:

img=(ImageButto n)e.Item.FindCo ntrol("ImageBut ton1");
imgID=img.Clien tId;

The ItemDataBound event is called once for each record in the DataSource.
That about as much as I can say with what you've given us, so hopefully you
can take it from here. Good Luck!

Re: how to get the control ID embedded in a repeater?

You must understand that when you put your control into Repeater or Grid
then that control will be repeated many time... once for each record in your
DataSource.

After you understand that you will easily understand that code
img = Repeater1.FindC ontrol("imagebu tton1")
does not make much sense. Since there are more than one ImageButton1

There are several solutions depending on what you want to do. If you want to
modify the image based on the data in a row then you need to subscribe to
ItemDataBound event.
That will get you access to particular row during binding. and then using
FindControl you will be able to find that ImageButton.
