Hi folks,
I have have 2 DropDownList controls with CascadingDropDown as state,
city respectively
and one textbox control as zip code.
when I change state value I get city value in other dropdown contol an
when I select City
I get the zip code in textbox.
so now when I first write zip code in text box I want to change the
values of dropdown
but I can't do so.
I get following exception
ArgumentOutOfRangeException was unhandled by user code
but here I can clearly find all the respective values of state and
city.
following is my code
aspx code
<span class="NormalText"> State,City and ZIP Code</span> <br />
<span
style="font-size: 8pt;" class="Asterisk">*</span> <%--<asp:TextBox
ID="txtState" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator3"
runat="server" ControlToValidate="txtState" ErrorMessage="Enter State

asp:RequiredFieldValidator>
