Hello maya,

Thanks for your previous reply

 Now i am doing like this

<ig:WebDropDown ID="ddlMRBID" runat="server" Width="100px">
</ig:WebDropDown>

and i binded like

Private Sub LoadDropDownMRBID()
    Dim result = From a In objContext.MRB_Ta
Select a.intRowID, a.vchMRB_ID

ddlMRBID.ValueField = "intRowID"
ddlMRBID.TextField = "vchMRB_ID"
ddlMRBID.DataSource = result.ToList()
ddlMRBID.DataBind()
ddlMRBID.AutoFilterTimeoutMs = 200
ddlMRBID.Items.Insert(0, New DropDownItem("", 0))
End Sub

and i set the selection changed event for this dropdown

Protected Sub ddlMRBID_SelectionChanged(sender As Object, e As Infragistics.Web.UI.ListControls.DropDownSelectionChangedEventArgs)

  Dim ad As String = ddlMRBID.SelectedValue

  End Sub

the selection changed event is not firing

once i set the auyopostflag:selectionchanged as Asynch (or) On ,it get firing this event

but still it showing the selected value as empty value (" ")

so that i tried to achieve through e.newvalue, by doing like this i get the selected text and proceed with  that "selected text" to the query and assigned to the "text box" value in the page from query
