I try to datbind a listview which is inside another listview InsertItemTemplate.
I'm binding the listivew in the parent listview onitemcreated events. I receive the error Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see: http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.
I've googled around for a couple of days now and tried different solutions posted here and there, but nothing has worked so far. Therefore I'm forced to write a new thread about this subject.
I'm working on a solution containing nested listviews. The top listview lists different projects, and in each project a nested listview lists images from that specific project using a nested sqldatasource. Inside the nested listview I want the user to be able to add new images, and i'm using the InsertItemTemplate of the nested listview. When inserting a new image, the project need to be specified, as the project is a foreign key in my image database. The problem is that in my InsertItemTemplate, "Bind" and "Eval" does not work (I believe this is by design). Therefore, when adding the new image I don't have access to the project. I'm using the ItemInserting event of the nested listview to upload the image, and the optimal solution would be to have access to the project in this event and just pass it on as a parameter.
Does anyone have any knowledge or useful links regarding this? In my scenario, there is a fileUpload inside the InsertItemTempalte of a detailsView which is (well was, not anymore) contained inside an UpdatePanel. I've ascertained that the fileupload needs a full postback, so I tried to set up a post back element in the triggers. However the controlID references a file upload in the InsertItemTemplate. when I tried to compile, the controlID was unknown. It's no big deal if the UpdatePanel gets scrapped. Nice to know if it can be done, though.
when I put the same thing in an insertItemTemplage I get the following: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. If I take out the selectedValue property, the status field is not populated. What am I missing? The following post ([URL]) references this but I didn't see any followup and, indeed, it does not work as follows:
Protected Sub lvTunes_ItemInserting(ByVal sender As Object, ByVal e As ListViewInsertEventArgs) Dim ddl As DropDownList = TryCast(e.Item.FindControl("ddlInsertTuneStatus"), DropDownList) e.Values("statusKey") = (Convert.ToInt32(ddl.SelectedValue)) End Sub
The Insert row in the ListView has an empty DropDownList and GetCountries() is not called. However, if I click the Edit button on an existing row, GetCountries() is called twice (not sure why) and the DropDownList is properly populated. Why isn't the InsertItemTemplate DropDownList getting populated?
I have a dropdown list in ListView control in InsertItem Template. I want to bind the DropDownList when I Click on Link. I want to bind it in CodeBehind not to use Datasource. I tryed lot but not finding the DropDownList. See My Code....

I am using a Listview with InsertItemTemplate bound to a LinqDataSource with a child table in the ORM datacontext. This table has a relationship with a parent table in the OR/M datacontext. The record is to be inserted in the child Table. The parent table is bound to dropDownList in the InsertItemTemplate to provide a user friendly name. Using the ListView ItemInserted event in debug, I can follow the execution and no errors occur BUT no record is inserted. I confirm this by a showing all Table Data in the SQL Mgmnt Studio. The child to parent table seems to be causing the problem because when I delete the relationship in the OR/M .dbml , I am ABLE to insert records. I am using Scott Mitchells' Using ASP.net 3.5 ListView with Data Pager controls: Inserting Data as a model. I can provide code if required, but what is going on with the deleting of the relationship between child and Parent.
Whenever my listview contains an InsertItemTemplate - the EmptyDataTemplate will not display when there are no records returned by the datasource. The microsoft documentation appears to back this up states this: If the InsertItemPosition property is set to a value other than InsertItemPosition.None, the mptyDataTemplate template is not rendered.
This seems like a silly restriction to place on such a powerful control - has anyone found a workaround so they can show both the Insert template and Empty templates at the same time?
Will someone show me how to access a textbox inside of a Listview InsertItemTemplate and EditItemTemplate? I've tried the following and it's not working:

I have a web user control to display and edit data. This control contains a save button and when i put the uc (user control) on a page and press the button everything works fine. When i put the user control inside a listview (enebling me to edit several items) everything works fine when i press the save button. But here is my problem: if i put the listview (containing my uc) inside an update panel and press the button, the uc page_load event is fired but the buttons click event is not. Ideas anyone?

I have a listview and in each there is a dropdownlist and a textbox. The textbox is invisible. When I change a value on the ddl it fires the SelectedIndexChangedMethod.

I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.

I have a listview with an EditTemplate. If I have one item in the listview, the following code throws a null exception which is called in the RowEditing event.
It does not throw an error if I have two items in my listview.The other strange thing is that it only throws an error when on a production server, but when I am testing locally, I do not get the error. Does anyone know why this behavior might exist?
