[Solved] Programmatically create Multicolumn ComboBox

[Andy]

Hi, I want to programmatically create a Prometheus ComboBox with multiple columns, databound to a datatable and added programmatically to a ASPX page.

Is this possible? 

I found references to sample code on creating multicolumn combobox controls (077086_ServerSideMultipleColumnsComboBox.zip) but this is a RadControls for ASP.NET sample that does not work with Prometheus.
In the method :public void InstantiateIn(Control container) on the line of code :DataRowView itemSource = (DataRowView)item.DataItem; the itemSource is NULL.

Thanks, Andy

Hi A,

Please find attached a project which illustrates the creation of a Multi-column template programmatically, using a Custom Template class.

I hope it is useful.

Kind regards,

Hi,
   I reviewed the sample code and the control is being declared inthe ASPX page. I am creating the control exclusively in the code behind class (CreateChildControls method). 

I have gotten the RADComboBox to display, the only problem I have now is that the dropdown background is transparent and clicking on the items does not select them. I can use the autocomplete feature to select items. Also the drop down selector button is not displayed but rather the text "select" is displayed.

Thanks, AL

Hello A,

You should manually register the skin used by RadComboBox on the page. Please read more about how to do this here.
