I have an error like below. I have inserted only the SharePoint drop down control alone in my application while clicking save it throws this error
SharePoint drop down control:
<SharePoint:DVDropDownList ID="ddl_Application" CssClass="form-control" runat="server" ></SharePoint:DVDropDownList>
'ddl_Application' has a SelectedIndex which is invalid because it does not exist in the list of items. Parameter name: value.
I don't know what i did wrong kindly help me to resolve this,Thanks in advance
