Hi,

 
It seems easy but I can't work out how to do this...

I am putting binding a TextBox in a Gridview:

 

                    <asp:TextBox ID="TextBoxZorgeenheidNieuw" runat="server" style="display:none" Text='<%# Bind("zorgeenheid_naam") %>'></asp:TextBox>

What I want:

• In Edit Mode: the textbox is always empty, even if a value is available
• If the textbox is filled in, the value is passed trough.
• Using the Bind() function
  

What I tried

Bind("module_naam", "")

 
Then the value was still visible 

Please help me out! 

If you haven't already done so, verify that your select and edit queries are correct.  I have had similar trouble previously when I modified my gridview/formview after it's initial auto-creation by the datasource I was using.  I had to go and recreate the datasource and then bind it to the gridview, which fixed lots of stuff for me.

You can use the Bind statement, but if you want the TextBox to be empty in the EditItemTemplate, then within the RowDataBound event, you'll have to retrieve a reference to this TextBox, and clear it out yourself. There's no data-binding expression I know of that will allow you this flexibility.

Thank you for your reply.

This is what I tried not to do :) But as there is no other possibility, I will use your suggestion. Thanks a lot!
