To retain the selected Gridview combobox column value.

[Lalitha]

Hi,
    I am using winform - gridview, 
    In this i used combobox column, i bounded  Itemname and Itemid  columns from the itemmaster table, Itemname as display member and Itemid as value member, i got Combobox with bounded the table values, but when i selected  the item name and swich to the next column it gets disapper. i need to retain the selected text in the combo text.
( Note: I am using empty Grid with no datasource, whenever I click the add new  button all the combo boxes will bound, when i  change the combo remaining columns gets the corrsponding values.)

Thanks & Regards,
S.Lalitha

Hello Lalitha,

Sorry for the inconvenience and thank you for reporting this issue.

We have found issues related to ComboBoxColumn when it is used in an unbound column. It will be addressed for the Q2 2008 release planned for the end of next month.

Your Telerik points have been updated.

All the best,

I'm having the same problem with a gridview bound to a datatable.  When a new row gets added to my grid and it reloads the first columns combobox value disappears.  If I click it it shows the right value but if I click anywhere else it disappears again.  Is there a work around?

Hi jerry,

I made tests for the case of a bound combobox column and I did not find any problems. Please check carefully your DataSource, DisplayMember and ValueMember properties.

If you continue having issues, please open a new support ticket and send us an example of your scenario. Thank you in advance.

I am using RadControls for WinForms Q2 2010 SP2.

I just changed from binding to a List<string> to a Dictionary<string, string> and am now experiencing the same issue. I need a work around or fix for this ASAP!

IDictionary<string, string> FilterValues = new Dictionary<string, string>();
...
comboValue.DataSource = new BindingSource(FilterValues, null);
comboValue.DisplayMember = "Value";
comboValue.ValueMember = "Key";

I didn't want to lose all the refactoring I did, so I decided for now to bind to

FilterValues.Keys

and had the same problem. For one, I can't bind to this as I get NULL reference error and have to use the above binding syntax.

Both the Dictionary and Dictionary.Keys return an ICollection<T> if that helps.

Hello Kris,

We have not experienced this issue before. Please note that the selected item of the RadGridView editor is restarted when you change the editor's DataSource. The Microsoft ComboBox control has the same behavior.

If you need further assistance, please open a support ticket and attach to it a sample project which demonstrates this issue. It will help me to investigate it further.

I am looking forward to your reply.

Best regards,
Alexander
