Forms Data Controls :: Bind() Inside Templated User Control Inside InsertItemTemplate Does Not Bubble Values?

Nov 10, 2010

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") #>'.

Forms Data Controls :: How To Access To Data Inside InsertItemTemplate Of A ListView

Jun 21, 2010

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.

Forms Data Controls :: Populating A DropDownList In A ListView InsertItemTemplate

Jan 19, 2010

I have the following ListView (extra code removed for clarity) :

<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />

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?

Forms Data Controls :: ListView InsertItemTemplate Executes But Nothing Inserted?

Mar 22, 2010

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.

Forms Data Controls :: Populating Dropdownlist Inside Listview Control Dynamically?

Mar 5, 2010

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.
