AJAX :: Refresh Cascading Dropdown From Client Side?
Apr 15, 2010
for the past 6 hours i have been going trough a million forum posts , I've been reading blogs , tutorials documentation and more.
Unfortunately, the amount of deprecated information is absolutely overwhelming.
All i'm trying to achieve is to change the value of a parent dropdown to something else, programmatically, and then have the child dropdowns to refresh.
By now I'm quite certain i have to use the function _onParentChange in some way.
Whit this function i can actually get the first parent to refresh, how ever the functions seems to be doing absolutely nothing when i call it on the child
I've been seeing a lot about using a context key and several ways to use it, but I'm not using a context key, do i have to use one?
i'm using the latest version of the toolkit whit visual studios 2008
i'm using only two dropdowns whit two extenders
here is the code:
where i can find proper client side documentation per toolkit control ?

I have this Linkbutton
[Code]....
This "CheckOut.aspx" has a UpdatePanel and inside the update panel is a Gridview,
my problem is when ever i made changes in the data of the gridview, the changes does not automatically displayed/showed/materialized in the gridview when ever i click the linkbutton to open Checkout.aspx page, temporarily i place a refresh button to do a server request and place Gridview.databind(); on its click event to update the gridview but when i close the Modaldialog, and open it again, the Checkout page is not updated again.
i try the <META-Refresh> thing, i try the location.reload(true) thing but it does not update my table.

I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?

Suppose parent dropdown is car (Values are car1, car2, car3)and its child is color(for car1 R Y G B, For car2 R Yand for car3 G B).Now on selection of car2 R and Y will appear and select R, then again made the change on car and select car3 then again select is comiing with G and B and select B.
Now if I select again in car, car1 then the child is populating with the values of car1 but it takes the B as a default value as it was previously selected and also present for car1 too.This case is only happen. on select of child value which is availble for both parent selection.

I am new to Ajax Control Toolkit, with the help of online tutorials I had created a cascading dropdown list in asp.net and tested it on my local machine. For this dropdown list data source would be an xml file (which is saved on my local machine c drive). I haven't encountered any issues until I deploy the precompiled web site on to IIS 7. When I open the web site from IIS I would see the two dropdown boxes on the web page with an error "Method error 500". I believe this error occured due to incorrect xml file
path provided on IIS. I had copied xml and xsd files into IIS server C drive but it did not help out and then I created a network map and placed the xml and xsd files in that shared folder tried to access that path from web service, it's working on local machine but not on IIS. It would be great, if any one could explain me the solution.
Following is the .aspx and .asmx code:
.aspx code:
<form id="form1" runat="server"> <div> <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> </asp:ToolkitScriptManager> <br /> <table> <tr> <td> <asp:DropDownList ID="DropDownList1" runat="server"
Height="20px" Width="257px"> </asp:DropDownList> <asp:CascadingDropDown ID="CascadingDropDown1" runat="server" Category="Category" TargetControlID="DropDownList1" PromptText="[select category]" ServicePath="~/WebService.asmx" ServiceMethod="GetCategory"> </asp:CascadingDropDown>
<br /> </td> </tr> <tr> <td> <asp:DropDownList ID="DropDownList2" runat="server" Height="20px" Width="257px"> </asp:DropDownList> <asp:CascadingDropDown ID="CascadingDropDown2" runat="server" Category="Type" TargetControlID="DropDownList2" PromptText="Select
Type]" LoadingText="Loading Type.." ParentControlID="DropDownList1" ServicePath="~/WebService.asmx" ServiceMethod="GetType"> </asp:CascadingDropDown> <br /> </td> </tr> </table> </div> </form>
.asmx code(.cs code):

XmlNodeList list = _doc.SelectNodes("/CategoryList/Category");
List<CascadingDropDownNameValue> categorylist = new List<CascadingDropDownNameValue>();
foreach (XmlNode node in list)
{
string catid = node.Attributes["value"].Value.ToString();
string catname = node.Attributes["name"].Value.ToString();
categorylist.Add( new CascadingDropDownNameValue(catname,catid));

I have 3 cascading dropdowns in a user control. I am trying to clear off the values of the dropdowns on the click of the clear or cancel button on the page. I am setting the value as selected index as 0 but the last dropdown never gets disabled. How do i achieve that. Is there a way that i can set only the first dropdown and the rest of the dropdowns get disabled.

Bit of a strange request but is it possible to set the selected value of a cascading dropdown in code? I have 2 dropdowns, the second is populated using the value of the first. Heres my markup:
<asp:DropDownList ID="ddlApplication" runat="server" CssClass="form"></asp:DropDownList>
<ajaxToolkit:CascadingDropDown
ID="cddApplication"
runat="server"
TargetControlID="ddlApplication"
Category="Application"
PromptText="[select an application]"
ServicePath="webservices/Application.asmx"
ServiceMethod="GetUserApplications" />
<asp:DropDownList ID="ddlDelegate" runat="server" CssClass="form" />
<ajaxToolkit:CascadingDropDown
ID="cddApplicationUser"
runat="server"
TargetControlID="ddlDelegate"
ParentControlID="ddlApplication"
Category="ApplicationRole"
PromptText="[select a user]"
ServicePath="webservices/ApplicationRole.asmx"
ServiceMethod="GetApplicationUsers" />
Basically I want to set the selected value of ddlApplication, then populate the ddlDelegate, then I want to set the selected value of ddlDelegate.

I have a web form where I have three dropdowns for Country State And City and there corresponding
ajaxToolkit:CascadingDropDowns.
The dropdowns are working perfectly fine with the web service methods. i.e country loading initially and then State as per selected Country and City as per the selected City.
The problem occurs when I try to set selected values in these dropdowns as per the Values previously saved.
The Country loads properly and the selected value is set according.
The State is filled as per the selected country but its selected value is not set.
The City is not loaded at all (as the state doesn't have a selected value)
The Code is as Follows:

Does anybody have a working example of a cascading dropdown inside the insertitem and edititem templates of a listview? I have been working on this for a couple of days now with only marginal success, and I fear I will have to abandon work on this due to time constraints.
The areas where I'm having difficulty are:
I just have two dropdowns(dds). In the insertitem row, I am able to have the user choose from dd1 and set a value in dd2. This works fine, but the user must be able to go back and change dd1 and have the proper value set as a selected default item in dd2. I can't get this to work.
In the edititem rows, I'm having difficulty setting the selected value of the dropdowns when displaying the row to be edited, and am running into the same problem as above when the user changes a dd1 value - the dd2 value does not reset to the proper selected default item.
My strategy for the edit items has been to try to get elements from the dataset bound to the listview to flow to the web service routines as contextkeys. I then iterate through the data values to be displayed in the dd and if the value = contextkey value, then set its isDefaultValue to true when adding it to the list of CascadingDropdownNameValue items.
The solution needs to work in the real world. That means Master Pages, so any fancy javascript workarounds need to take this into account.
