Bind Data to an Image Control not in a Data Presentation Control
I've been searching for two days but I don't really know what to search for.I'm making a site for a photographer.  The Default.aspx page displays Albums by showing a title, image and description from the database table Albums. Click an album to view the contents and it passes the QueryString which is AlbumName.  The ViewAlbum.aspx page uses the QueryString to display an UpdatePanel holding a Large Image and a Repeater full of dynamically filled ImageButtons for thumbs.  Both are from the database table Photos and are retrieved using an ObjectDataSource.

Using Data Controls Without Using ObjectDataSource Control
Hi, I've been looking on the Internet for a tutorial that would show me how to use the data conrols (FormView, GridView etc) without using an ObjectDataSource (or any other data source control).  The reason is that I want to use a formview and gridview from within another formview control to create a single form  that would allow me to insert, update and delete an order and its order details at the same time. I thought that this could be achieved by having a DataSet containing two DataTable objects in the code-behind with the Order DataTable containing one row to repres...

ajax control in data presentation controls
can i add ajax controls (MaskedEdit) to presentation controls (dataGrid, dataForm)?? Hi,of course. But keep in mind that those controls are extenders, so you append them to an existing control.

Actually, if you looked at the source code for the Masked Edit Extender, you'd see  [TargetControlType(typeof(TextBox))]Meaning, targeting any control type other than textboxes...

Visibility control of Panel control and its affect on data controls
Thought I would toss this out here this morning and perhaps someone else had run across the same issue and had found a good way to accomplish what I want. First let me state what I'm attempting to do and the problem that I've run into.  GridView1 has a collection of rows in a SQL table that I want to present to the user. I've provided them the options of sorting and selecting only from the GridView control.  Orgionally, I had created a detail view that was being presented in Edit mode and then customized the layout of the edit item template to suit my needs.&nbs...

Mapping data/text fields using a control WITHIN another control (.ascx page)
I have created a custom user control that renders two links:Pick from Contacts and Add to Contacts ...and that also auto-generates javascript to map certain attributes of the control to certain text fields.
