Image Not Displaying in Nested Template View

[Kevin Mauriello]

I took your example from Grid/Herarchy With Templates, other than the database fields being different the only change I made was to replace:

this

<img  src='<%#  Page.ResolveUrl("~/Grid/Examples/Hierarchy/NestedViewTemplate/Img/") + (Container.FindControl("Label1") as Label).Text %>.jpg' alt="Customer Image" />

with this:

<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource4">

<ItemTemplate>

<telerik:RadBinaryImage ID="RadBinaryImage1" runat="server"

DataValue='<%#Eval("Avatar") %>' Width="90px" Height="110px" ResizeMode="Fit"/>

</ItemTemplate>

</asp:DataList>

I need to retrieve the image from the database.
The first image is correct, but all images after that fail.  When I modify the PreRender to loop through each item and expand each item it works fine, for the first page (the second page is all empty images).

I have a feeling this is going to be a dumb mistake by me, please help.

Here is what it looks like:

Hello Kevin,

Can you please verify that the RadBinaryImage/its binding container is databound when the NestedViewTemplate is expanded. Also can you please provide a bit more information about the grid's declaration, some code snippets etc.

Kind regards,

That did it, I put the datalist.databind in the itemcommand event.

Thanks

Hello everyone,

Regarding this issue, how can I reference the Datalist control if it is nested in the the grid. I try to reference it within the code behind and can't get it done. I use advance databind for the Grid and also have to use it for the datalist. In which event should I put my code?

Thanks!
Miguel

As with other regular web grid, you should be able to listen for the ItemCreated or ItemDataBound server event and locate your nested datalist using e.Item.FindControl(datalistId) method. Inspect this doc for details about these two telerik grid events.
