Hello, Thank you for submitting your query with the ComponentArt forum. I tried to reproduce the issue by making a sample application based on the information provided by you. In the sample, I have used an html button and on the click of this button, I am invoking the client side focus method of the ComboBox. On running the sample, I observed that the focus is applied to the Combobox without any issue. Also on receiving focus, the combobox is not automatically auto expand. I have checked this behavior...

My guess this is in a callback grid. There is currently an issue with the combobox, which is that the Grid isn't re-initializing these combos. One thing to do would be on Callback Complete client event, initiailze the combobox. < script > function Grid1_onCallbackComplete(sender, e) { ComboBox1.Initialize(); ComboBox1.Initialize(); } </ script > ...this is correct, we initialize twice... < componentart : Grid ... > < ClientEvents > < callbackcomplete eventhandler =...

Hi, How can I add a ComboBox to a DataGrid, and populate the values in the ComboBox from a list on earch object populating the rows in the DataGrid? I set the ItemsSource on the DataGrid in the codebehind. I've seen the editing sample where a "static" ComboBox is shown inside a grid. I have tried various ItemSource Binding expressions on the ComboBox without any success. -JJ

I have ran into a strange issue with the ComboBox combined with multiple UpdatePanels and the ComboBox being hosted in a Dialog. If the dialog, which is contained an UpdatePanel, is displayed by setting the IsShowing property equal to true during a partial page postback initiated by a button in a different UpdatePanel, the ComboBox dropdown arrow does not work initially. If you place the cursor in the textbox and press the down arrow key on your keyboard and THEN click the dropdown arrow it begins...

When a ComponentArt combo box is used inside ComponentArt Grid -as an edit template for specific cell:
- When ComboBox is bound to data collection (ObservableCollection), and when total items are more 900 (max 1200) -even for this list, performance is very bad
- ComboBox opens up after a long time
- Type-ahead and other operations are also very slow.
NOTE: If I replace Component Art ComboBox, with native Silverlight ComboBox, performance is lot better.
Please let me know if...

I was using the greg's ID as he is the POC for our license but I'm the one evaluating the Silverlight components for a customer. To answer your question, no the combox dropdown is closed when I leave the page. It drops down when I return to the page. I tried putting another control in front of it to see if it would receive the focus but that didn't work. Paul

Hi,
Is the Combo-Box open when the browser window loses focus? The control should not open if it was not open in the first place.
Please advise,
Thanks,
Jeremy

I have a CA ComboBox as the first control on my page. It's a simple country list databound via a WCF service. No problem. However, when the browser window (IE7) loses focus then regains focus the ComboBox shows the dropdown list again. Is this by design? I'm using Web.UI for Silverlight 2009.2 Thanks
