I am using C#.  
I can dynamically create a template column but how do I place a
checkbox control in the column header?

I get this exepction
"Could not find a property named 'COM_NAME' on the type specified by the
DataObjectTypeName property in ObjectDataSource 'ObjectDataSource1'."
when i try to update a detailgrid or form.

Is there a way to reference the objects within this template?   I need to
add a file upload object (which I can do) but then need to know how to
reference that from an event so that I can then upload the file.
Thanks in Advance

I have a problemin a webcontrol datagrid

I have a calendar control in an EditItemTemplate on a DetailsView which
works fine, until I switch to a record in Edit mode which has no date in

the DropDownList the table does not get updated with the new value. I'm new
at this and I'm sure I'm overlooking something simple ...

I have a page that has one to many dynamically built datagrids on it. Each
row in each grid has a link button. When you click the button the post back
occurs but not the event handler for the button.
As I build the grid I add the event handler like so:

I'm creating a dynamic datagrid using Dim objbc As New BoundColumn, etc. The
datagrid is populating correctly. I am also using first column of grid as
'edit', on clicking this the update link is displayed and textboxes are
returned. All good so far.

I have a checkbox next to each record in my datagrid that I want t
either hide or display depending on whether the checkbox is checked.
I want to hide/display the rows not the columns. This is what I came u
with so far but maybe there's a better way?  Thanks.

I am familiar with creating TemplateColumns in dataGrids which contain a
checkbox control. I have successfully implemented deletion routines, where,
upon a button_Click event, mulitple items are deleted from the dataGrid.
For example, this loop might be inside of my button_Click ...
