I have an <asp:ListView> but for some reason the LayoutTemplate section does not show when the list is empty, although the <EmptyDataTemplate> section shows. The LayoutTemplate contains the headers for the table, and I want to show an empty table when there are no items in the datasource, not just the content of EmptyDataTemplate.If there is no choice I will copy the LayoutTemplate into EmptyDataTemplate.

Is there any way to enable alternative ListView (LV2) or any other control in case when ListView (LV1) returns no records from DB? I already have emptydatatamplate designed for this case, but I need to enable a new ListView below in this particular case and I don't know how to achieve this!

I have created an ITemplate property, I can set the layout in the aspx page, and I am doing ITemplate.InstantiateIn(myControl).
But I can't figure out how to insert controls at the placeholder. I'm guessing it would be something like MyTemplate.FindControl("itemPlaceholder").Controls.Add(myControl). I tried casting to the type of my ITemplate, but I get the error:
Unable to cast object of type 'System.Web.UI.CompiledTemplateBuilder' to type 'MyNamespace.MyLayoutTemplate'
Edit: I just found this: http://www.nikhilk.net/SingleInstanceTemplates.aspx Control developers can define templates to be single instance using metadata which causes the ID'd controls within the template contents to be promoted to the page level... The parser and code-generator together work behind the scenes to add member fields, and initialize them at the right time.. It seems to be only for user controls? I tried Page.FindControl() after doing this but it didn't find anything.

I'm binding the listview to a collection attached to my nHibernate model object (SearchObject.SearchItems). This collection doesn't have insert or update handling like an object datasource would, so I want to handle the insert/update events manually. Is there a way to get these values to come through automatically, or do I have to manually grab each value from its control when I handle this event?

View 1 RepliesI have a paged ASP.NET ListView. The data shown is filtered, which can be controlled by a form. When the filter form changes, I create a new query, and perform a DataBind.
The problem however, when I go to the next page, and set a filter, the ListView shows "No data was returned". That is not weird, because after the filter is applied, there is only one page of data.
So what I want to do is reset the pager. Is that a correct solution to the problem? And how do I do that?
