OnItemDataBound registers Link Buttons in List View to Update Panels Script Manager, However, They only Work...
I have an update panel with ChildrenAsTriggers set to true so there is no actual script manager defined on the ascx file or in the code behind file.
Inside there is a list view, whos OnItemDataBound calls this function:
// ------------------------------------------------
// Register Update Panel Async Postback Triggers for View Order Buttons
// ------------------------------------------------
protected void orderListView_ItemDataBound(object sender, ListViewItemEventArgs e)
{
var scriptManager = ScriptManager.GetCurrent(Page);
LinkButton lbOne = e.Item.FindControl("viewOrder") as LinkButton;
scriptManager.RegisterAsyncPostBackControl(lbOne); // ToolkitScriptManager
}
This is supposed to take the LinkButton inside the List View, and register the buttons so a hard refresh does not occur when it is clicked.
For some reason, it only works on the first click of the link button in the list view. If I click it again, it does a hard refresh and buttons no longer seemed to be bound.
Any suggestions on why this may be?

If I put an UpdatePanel on the page without a SciptManager I get the error "The control with ID 'UpdatePanel1' requires a ScriptManager on the page". How did you get around this?

I believe its because ChildrenAsTriggers="true" is flagged on the update panel after runat="server"

Noe that does not matter. Are you perhaps using a Master page? And could have that page the ScriptManager?

Sorry, I misspoke, this is likely the case as it's an ascx file not an aspx file.

Ah, then the SciptManager is on the page itself. But that does not explain your issue. Everything in an UpdatePanel automatically does a Async PostBack. So there should be no need to register that Control withScriptManager.RegisterAsyncPostBackControl(lbOne). I cannot reproduce the issue...
