Hi ,

I have a repeater with an image button. (.net c#)

This i do in my code behind in de ItemDataBound:

Code: C# 
ImageButton deleteImage = (ImageButton)e.Item.FindControl("deleteImage");
                deleteImage.CommandArgument = String.Format("{0}/{1}/{2}", basketLine.Product.Family, basketLine.Product.Number, orderListId);
                EO.Web.CallbackTrigger trigger = new EO.Web.CallbackTrigger(deleteImage.ClientID, "deleteImage");
            OrderListCallbackPanel.Triggers.Add(trigger);


If the callbackpanel loads i get this error :

Trigger control 'rpProducts__ctl0_deleteImage' for Callback 'OrderListCallbackPanel' does not exist.

Any one ?
If you need more info , let me know.

Greetings

Hi,

You won't be able to do it that way. When the CallbackPanel searching for triggers, it searches within the CallbackPanel control's naming container. Since your image button is in a different naming container (the repeater itself implements INamingContainer), so it won't be able to find it.

You can use eo_Callback to trigger the Callback. Instead of using an ImageButton control, you can use regular HTML:

Code: HTML/ASPX 
<img src="some_image.gif" onclick="eo_Callback('CallbackPanel1');"  />


That will also trigger the callback. For more information about eo_Callback function, check Client Side API Reference -> Global Functions in the help file.

Thanks
