  creating 2-way databinding templatefields programmatically

  May 25, 2006 09:02 AM|LINK

  Hey guys, really struggling with this one..
  
  I have a detailsview control which I am adding fields to programmatically.
  
  I can add in template fields, but I cannot for the life of me figure out a way to Bind them to the datasource?
  
  Declarativly, the below works perfectly fine, and updates back to the datasource..
  
  <asp:TemplateField HeaderText="body" SortExpression="body">
      <EditItemTemplate>
          <asp:TextBox ID="TextBox1" TextMode="MultiLine" runat="server" Text='<%# Bind("body") %>' />
      </EditItemTemplate>
  </asp:TemplateField>
  
  
  But how can you do it programmatically?  How can i specifcy what to bind it against?

  I am doing the same thing as you but with a GridView.  I am able to get the fields to display data but not update by creating a custom TemplateField class.  I see this was done a while back, so if you are still interested, I'll post code as to what I have done so far.  The only thing I cannot do is get data to bind going back to the datasource on the update command.

  You're pretty much stuck at the same point I was. That is, getting the data to update against the datasource.
  
  I gave up :)
  
  Let me know if you have any further success.

  DaRKoN_,

  I can get this to work perfectly when i don't use ItemTemplates for my textbox edit controls.  When I use BoundFields, the whole process works just fine.  The only thing is I don't have any control over the width of the text box.  That was the whole reason for me going to an ItemTemplate.  I have other messages out to see how I can programmatically set the ControlStyle member of the BoundField class just to get out of this nightmare.

  Yep, again, exactly the same issue I had. I could do absolutely everything, but define how to setup 2-way databinding (that is, being able to pull data out, as well as push data back in) with *programmatically* created template fields.
  
  As an aside, you could easily use CSS to get around your problems
  
  #gridIDname input
  {
      width:100px;
  }
  
  for example.

  I realize this is an old topic but I came across it searching for the same answer.  I have resolved the problem for myself, see my post here:

  Short Story:  Override the RowUpdating event (or FormUpdating or whatever control you're using) and add the fields manually to the keys.
