Hi Palavesh,

Of course. You can do it like this.

State:<asp:DropDownList runat="server" ID="dlState">
</asp:DropDownList>
City:
<asp:DropDownList runat="server" ID="dlCity" >
</asp:DropDownList>
District:
<asp:DropDownList runat="server" ID="dlDistrict">
</asp:DropDownList>
<cc1:CascadingDropDown ID="CascadingDropDown1" BehaviorID="myCDEState" runat="server" TargetControlID="dlState"
Category="State" ServicePath="../WebService/CityServiceOledb.asmx" ServiceMethod="GetStates" LoadingText="[Loading...]" PromptText="Please select state">
</cc1:CascadingDropDown>
<cc1:CascadingDropDown ID="CascadingDropDown2" BehaviorID="myCDECity" runat="server"TargetControlID="dlCity" ParentControlID="dlState"
Category="City"PromptText="Select a city" ServicePath="../WebService/CityServiceOledb.asmx"
ServiceMethod="GetCities" LoadingText="Load cities..." >
</cc1:CascadingDropDown>
<cc1:CascadingDropDown ID="CascadingDropDown3" BehaviorID="myCDDistrict" runat="server"TargetControlID="dlDistrict" ParentControlID="dlState"
Category="District" PromptText="Select a district" ServicePath="../WebService/CityServiceOledb.asmx"
ServiceMethod="GetDistricts" LoadingText="Load districts..." >

Hi Palavesh,

You have four CascadingDropDowns on the page, I suggest that you should add a CascadingDropDown for Dlstate. To debug it , please reference to thisthread.
