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:

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.

AJAX :: UpdatePanel PostBack Trigger - Control Inside InsertItemTemplate?

Dec 31, 2009

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.

Forms Data Controls :: ListView DropDownList In EditItem And InsertItemTemplate

Mar 6, 2008

I have the following in an editItemTemplate of a ListView control that is powered by a LinqDataSource (and it works great) :

<tr>
<th>status</th>
<td>
<asp:DropDownList
ID="ddlInsertTuneStatus"
runat="server"
DataSourceID="linqTuneStatus"
DataTextField="status"
DataValueField="statusKey"
selectedvalue='<%#Bind("statusKey")%>'>
</asp:DropDownList>
</td>
</tr>

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

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

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 :: Listview - EmptyDataTemplate And InsertItemTemplate Can't Coexist?

Aug 20, 2008

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?

Web Forms :: Can't Find FileUpload Control Inside ListView

Jan 25, 2011

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.

Here's my relevent codebehind:

protected void AccessDataSource1_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
FileUpload FileUpload1 = (FileUpload)ListView1.FindControl("FileUpload1");
string Fupload = FileUpload1.FileName.ToString();
DateTime DateNow = DateTime.Now;
string DateNowSTR = DateNow.ToString();
string NewImageName = DateNowSTR + Fupload;
FileUpload1.SaveAs(Server.MapPath("~//images//" + NewImageName));
e.Command.Parameters["SponLogo"].Value = NewImageName;

AJAX :: DropDownList Don't Work Inside ReorderList InsertItemTemplate ?

Aug 17, 2006

In want to have a DropDownList inside the InsertItemTemplate of my ReorderList.

Like this:

<asp:DropDownList ID="NewRecipientsList" runat="server" Width="180px"
DataSourceID="NewRecipientsSrc" DataTextField="UserName" DataValueField="UserId"
SelectedValue='<%# Bind("UserId") %>' />

But I get this error message at runtime: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

Which I don't understand. Using a TextBox instead works perfectly: <asp:TextBox ID="Test" runat="server" Text='<%# Bind("UserId") %>' />

And using the dropdownlist in other controls, like FormView or DetailsView does work. I can't understand why the combination of ReorderList + DropDownList doesn't work.
