    Posted: 24-Jul-2007 at 1:22pm
Whenever I try to configure the databindings for a DataGrid View Binding Manager, the Control Type combo box is empty. Furthermore, after clicking the Control Type combo and then closing the Configure Databindings Window (accepting or discarding any changes) a messagebox appears with the following message:
 
The following exception occurred in the DataGridView:
 
System.ArgumentException: DataGridViewComboBoxCell value is not valid.
 
To replace this default dialog please handle the DataError event.
 
Any idea why this is happening, and how to fix it?
 
Thanks.

When you configure the binding sources, you will also need to fill the combobox in your datagridview with the values that you want.  Here is an example:

(Declare the private member)
private EntityList<ReleaseStatus> mReleaseStatus;
 
(Then fill the combo box with entities)
mReleaseStatus = mPersMgr.GetEntities<ReleaseStatus>();
dataGridViewComboBoxColumn1.DataSource = mReleaseStatus;
dataGridViewComboBoxColumn1.DisplayMember = "Releasestatusdesc";
dataGridViewComboBoxColumn1.ValueMember = "__Self";
 
Hope that helps!

It's not my code that is causing the problem - it's the IdeaBlade DataGridViewBindingManager when I right-click the DGVBM in the designer and select "Configure Databindings".
 
I can drag Properties onto the right side of the dialog, but the control type column for the dragged property is always empty and cannot be changed.

Sorry...I misunderstood.  I checked the behavior and I am getting the exact same results.  Valueless control lists and the same error when striking cancel.  What version are you running?

No problem, after re-reading my initial post, think I could have worded it a little better!
 
Anyway, I am using Version 3.5.2.3

Yep...same here.  I just upgraded yesterday to the new version.  My application builds and publishes beautifully, but these DGVBMs are not working.  I called support and spoke with David Klitzke.  He was able to duplicate the problem and is looking into it right away.

It is definitely a bug.  We have a fix that we are testing now.  The plan is to put out a new release (3.5.2.5) that replaces the current release (3.5.2.3).  This should happen by the end of this week.  The ONLY difference between 3.5.2.3 and 3.5.2.5 is this one bug fix.

David,

Will the update also include the support for DevX 7.2.1?  Or is that still forthcoming?

Thanks,

--Jeff

The fix for this bug ("Cannot set Databinding Control Type") is now available in the download area as DevForce 3.5.2.5.
