Hi,

I am trying to use an Update control  inside of a web user Control and I keep getting error messages that say my Datalist which I put within the update user control is not recognized. Is it that I can not use an UpdatePanel Control in a user control??

hello.

well, yes, you can  use an updatepanel inside the user control. are you getting an error or a warning in the design environmente of the VS?

Here is a sample of the sort of error message I get

Error 2 Type 'System.Web.UI.UpdatePanel' does not have a public property named 'GridView'. 
Error 3 Type 'System.Web.UI.UpdatePanel' does not have a public property named 'Columns'. 

Error 4 Type 'System.Web.UI.UpdatePanel' does not have a public property named 'TemplateField'. 
Error 5 Type 'System.Web.UI.UpdatePanel' does not have a public property named 'ItemTemplate'. 

hello again.

can you show us a snippet of the updatepanel declaration?

Hi,

hello.

hum...i'm not seeing the trigger declaration here...how are you performing that operation? can you show us how you're creating the trigger?

hi,

Instead of hyperlink use link button.Because as per my knowledge trigger required event name and hyperlink does not fire any event.

Can you share your trigger code with us.

The HyperLinks are used for the DataList Pagination. Basically what I want to do is when the Next or Previous Links are clicked, the DataList should be updated . Are you sure using a Link Button is better than me using the HyperLinks as I already am??

hello.

question: how about putting the hyperlinks inside the updatepanel?

Hi, Use LinkButton rather than hyperlink!  

ControlID Property

Gets or sets a string that represents the ID of the control that is a trigger for the UpdatePanel control.

The ControlID property must be set to the ID of a control that implements the INamingContainer, IPostBackDataHandler, or IPostBackEventHandler interface.
