Is there something I'm missing. I get the drag and drop to work but I cannot get the profile setting to save. It resets the setting on a postback.
Did you try to use Fiddler or Nikhil's browser helper to monitor the exchanges with the profile service and see if there's an error message there?
I've searched high and low for what seemed would be a simple and frequently used method to access the properties of a drop down contained in a Ajax UpdatePanel without finding anyone who seems to have needed to do this or who has solved it. Maybe Microsoft decided nobody would ever want to do such a weird thing!
I have users with various permission levels. Depending on their level, on page load I need to disable drop downs which are contained within Ajax Updatepanels.
I can expose the properties of the UpdatePanels themselves but they do not support the enable property, only invisible which is no help.
Anyone know how this is done ?
Thanks
Aren't you able to just set the Enabled property of the appropriate DropDownList's?
Use CascadingDropDown control in AJAXControlToolKit
http://www.asp.net/AJAX/AjaxControlToolkit/Samples/CascadingDropDown/CascadingDropDown.aspx
Hi,
Are you using the AJAX extension version 1.0.61025.0 ?
I'm using this one. The controls inside UpdatePanel can be accessed directly. For instance:
<%@. Page Language="C#" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"> protected void Page_Load(object sender, EventArgs e) { DropDownList1.Enabled = false; }</script><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title>Untitled Page</title></head><body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:DropDownList ID="DropDownList1" runat="server"> </asp:DropDownList> </ContentTemplate> </asp:UpdatePanel> </div> </form></body></html>
dir sair
when i add any ajax control in wesite using ajax template i cant using prifix ajaxtoolkit
i must drag and drop the control and his prifix will be cc:
ex: cc1:modelpopupextender
can i know whay?
thank you
here cc1:modelpopupextender means customControl:modelpopupextender
u have to register the AjaxToolKitControl
<%@. Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>
this line apperd on top of head section like Page
then u can drag and drop the control
that time it will generate ajaxToolkit: modelpopupextender
Thank
Kunal
Hi,
Another tip is that you can register it in web.config so that don't have to do it in everypage.
<system.web>
<pages>
<controls>
<add assembly="AjaxControlToolkit" namespace="AjaxControlToolkit"tagPrefix="ajaxToolkit"/>
<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</controls>
</pages>
Hope this helps.
want to know whether i can pass more than two arguments in the above shown webservice method..i intend to implement it in a cascading drop down list.. having two sibling dropdown lists...
so i want to pass three arguments eg..cid, brid, deptid...but a webservice allows only two of the kind...
Hi,
You can pass more information via a third parameter contextKey. For instance:
public static AjaxControlToolkit.CascadingDropDownNameValue[]
GetDropDownContentsPageMethod(string knownCategoryValues, string category, string contextKey)
protected void Page_Load(object sender, EventArgs e)
{
CascadingDropDown2.ContextKey = "contextKeyOf2";
}
Hope this helps.

Hi,
I think you should try it by yourself before you ask!
Anyway,I found this question is answered by Jonathan Shen – MSFT athttp://forums.asp.net/t/1183703.aspx

Thank you. Jonathan shen's reply was for my post only. I have gone through the post.

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">

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.

I want to grab to X/Y coordinates and save them someplace other than the Profile database. Is there an eventarg description that shows the eventargs for the DragDrop control?
Thanks!
I am after the exact same information as I need to have one user with several layouts. Did you come across this information in the end? Or alternativley is someone able to offer any advice/examples.
Many thanks
Mark
I'm curious. Do youhave to use a Web Service when trying to pull items for a cascading drop down from a database or is there another (perhaps simpler) way? I'd love to be more enlightened on the subject. Thanks in advance.

Note: You should add two tables with the name "tb_State" and "tb_City" into your Database ,which is used in your project , before you using this demo.
Table "tb_State" has two fields with the name "StateID"(primarykey) and "StateName"(Text).
Table "tb_City" has three fields with the name "CityID"(primarykey)、"StateID"(Number) and "CityName"(Text).
I'm curious. Do youhave to use a Web Service when trying to pull items for a cascading drop down from a database or is there another (perhaps simpler) way? I'd love to be more enlightened on the subject. Thanks in advance.
We are not limited to use Web Service. Sometimes, we may add the implement code into our *.cs file directly. Here is the sample:
using System;using System.Web.Services;using AjaxControlToolkit;public partialclass CascadingDropDown_CascadingDropDown : CommonPage{protected void DropDownList3_SelectedIndexChanged(object sender, EventArgs e) {// Get selected values } [WebMethod] [System.Web.Script.Services.ScriptMethod]public static CascadingDropDownNameValue[] GetDropDownContentsPageMethod(string knownCategoryValues,string category) {//obtain data from Database.
return;
}}
Note: We needn't to set the ServicePath property for the control in this case. Just like below.
<ajaxToolkit:CascadingDropDown ID="CascadingDropDown2" runat="server" TargetControlID="DropDownList2"Details please dip into the Ajax ControlToolkit source code.
Category="Model" PromptText="Please select a model" LoadingText="[Loading models...]"
ServiceMethod="GetDropDownContentsPageMethod" ParentControlID="DropDownList1" />
If I misunderstood you, please let me know.
Thanks for the information. I really appreciate it. Now, however, I've progressed to the point where I need to understand more of the error codes that are given. Most specifically, error 12030, as found in my thread here: http://forums.asp.net/t/1138732.aspx
Thanks again.
Hi Venom,
Error code: 12030
ERROR_INTERNET_CONNECTION_ABORTED
The connection with the server has been terminated.
In your case, it seems like your webservice doesn't work properly.I suggest that you should add break points into your webservice and debug step-by-step.
Note: If you made some modifications in your webservice and before you debug , please reset your aplication by saving your web.config file.Good luck!
