GridView DataBinding Questions

[Martin]

Hi,

I have a problem using the

• GridViewCheckBoxColumn
• GridViewComboBoxColumn

When I edit data in a "GridViewDataColumn" and execute my custom "UpdateItemCommand" I have no problems and my SelectedItem displays the changes which were entered in the "GridViewDataColumn".
However the problem occurs when I edit a "GridViewCheckBoxColumn" or "GridViewComboBoxColumn". The SelectedItem does not display the changes made by these Columns.

Thank you for your help!

Hi Martin,

I was not able to reproduce your scenario. I am sending you the sample project I used for testing it. Please take a look at it and let me know in case of any discrepancies according to your requirements.
 

All the best,

Hi Maya,

thank you for the help. I noticed that my Code actually works, I just need to "Enter" the changed Combobox before storing the Data.
