Hi,
I am working with a web application which uses the WebDataGrid and a DropDown EditorProvider for a Column.
When I add Items to the Collection and build the web application it throws an error lik this
Infragistics.Web.UI.ListControls.DropDownItemCollection must have items of type
'Infragistics.Web.UI.ListControls.DropDownItem'. 'infragistics.web.ui.listcontrols.dropdownitem'
is of type 'System.Web.UI.HtmlControls.HtmlGenericControl'.
I am using NETAdvantage for ASP.NET WebClient 2010 volume 1 (trial version).
Please Help.
Thank You
Praveen
Hi Praveen,
Can you send me more information regarding the error and how to produce it. Also do you have the namespace Infragistics.Web.UI.ListControls included in the register clauses in the web site or the web.config file? The namespace should be added manually or by dropping a new WebDropDown control on the page, before adding items to the control.

Hi Magued,
Thanks for Your reply.
As per your reply I add this Register tag prefix
<%
@ Register assembly="Infragistics35.Web.v10.1, Version=10.1.20101.1011,
Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb"
namespace="Infragistics.Web.UI.ListControls" tagprefix="ig" %>
at the top of the page and it worked fine.
But when I bind Items from an SqlDataSource it throws this error
The control collection cannot be modified during DataBind,
Init, Load, PreRender or Unload phases.
Please help.
