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.
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.
I have a Listview that houses a FileUpload control. However, after using findcontrol the next line of code tries to convert the filename into a string and produces the familar error object reference not found.
Note: I have used identical code in a formview and it works fine.
I have some controls that are inside a ListView The ListView is inside a View1 The View1 is inside a MultiView1 (You could make a song out of it) How do I find e.g. a Label control inside the ListView. This line of code worked fine until I threw the ListView inside the MultiView
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. In here, if the ddl is certain value I want to show the textbox thats on the same row. How do I grab the textbox from inside this method?
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.
