AJAX :: How To See When DataBind Is Called
Dec 6, 2010
I have a user control with cascading dropdownlists. When I populate the controls in the Page_Load event, the second dropdownlist has duplicate entries. These controls are inside AJAX UpdatePanels and I need to find out when DataBind is called on the second dropdownlist to see why it is being called twice.
I am using a SqlDataSource with a ControlParameter to populate the second dropdownlist, not doing it through the code behind.
Is there a window in Visual Studio 2008 that will let me see when DataBind is being called?

I'm trying to resolve correct paths to javascript scripts in my head section using:
<script src="<%# ResolveUrl("~/Scripts/jquery-1.4.2.min.js") %>" type="text/javascript" />
In order to resolve the path I need to call databind using Page.Header.DataBind(); What event should I place the databind call in?
[URL]
When I put it in Page_Load as the article it works (only for firefox), but I wonder if this is the correct place.
When I follow this article IE 8 renders:
<script src="/Scripts/jquery-1.4.2.min.js" type="text/javascript" />
and firefox 3.6 correctly renders:
<script src="../../Scripts/jquery-1.4.2.min.js" type="text/javascript" />
Update:
Fixed browser issues by updating a script reference in a referenced user control to use ResolveUrl. Now browser issues are fixed. Still wondering where to put Databind.

Anyone with similar conclusion? GridView does not databind/refresh upon postback unless the postback is called by itself?

I am new to ASP.NET (2 months) and my very first assignment is to create a website for a municipality. Purchasing as much reading material as possible, I got started and after some time, I have a decent website (coded in C#) that is ready to be internally tested on the departmental webserver. The Web server is running IIS 7 and the pages were developed with Visual Studio 2010. On the main default page, I wanted to implement a slide show using the AJAXControlToolkit which I installed. I watched the ASP.net tutorial [URL] and literally coded my slide show verbatim. I try to launch my slideshow within my default.aspx page and absolutely nothing happens. The steps that I took are
1. Created a webservice (SlidesService.asmx) which generated a code behind file (SlidesService.cs).
2. I created the web method GetSlides() containing a 22 element array which I place in the code behind file.
3. Implement the ToolkitScriptManager establishing my image control.
4. Defined my Previous, Play and Next buttons.
5. Implemented my SlideShowExtender providing my SlideShowServicePath and SlideShowServiceMethod.
Assumptions: In doing all of the above, I noticed that the SlidesService.asmx file needs no code (as I placed all code within the codebehind file). The SlidesService.cs code behind file should reside in the App_Code folder whereas the the SlidesService.asmx file can remain in the root folder. No Button e.g Button_Click needs to be attached to the code behind source file. If I have conveyed my steps properly, can anyone shed some light on why when clicking the play button, nothing happens? Code is listed below.
[Code]....
SlidesService.asmx - code
<%@ WebService Language="C#" CodeBehind="~/App_Code/SlidesService.cs" Class="SlidesService" %>

I'm having some trouble getting this to work. basically I got the modalpopup to show, and when it's shown i have 2 buttons (Yes and Cancel). When yes is clicked i want a function to be called. Here is my asp.net code:
----------------------------------------------------------------------------------------------------------------------
<asp:Button ID="btnMpeDummy" runat="server" Text="Test" style="display:none" />
<ajaxtk:ConfirmButtonExtender ID="cbeDelScn" runat="server" TargetControlID="btnMpeDummy" DisplayModalPopupID="mpeDelScn" />
<ajaxtk:ModalPopupExtender ID="mpeDelScn" runat="server" TargetControlID="btnMpeDummy" PopupControlID="pnlDelScn" OkControlID="btnDelScnYes" CancelControlID="btnDelScnCancel" BackgroundCssClass="modalBackground" />
<asp:Panel ID="pnlDelScn" runat="server" CssClass="modalDialog" style="display:none; width:300px;">
<asp:UpdatePanel ID="upnl3" runat="server" ><ContentTemplate >
<asp:Label ID="lblDelScn" runat="server" Text="Delete Iteration" />
</ContentTemplate></asp:UpdatePanel><br /><br />
<asp:Button ID="btnDelScnYes" runat="server"
Text="Yes"
ToolTip="Yes"/>
<asp:Button ID="btnDelScnCancel" runat="server"
Text="No"
ToolTip="No" />
</asp:Panel>
----------------------------------------------------------------------------------------------------------------------
And here is my VB code:
Protected Sub btnDelScnYes_Click(ByVal sender As Object, ByVal e As UI.UIIterationList.IterationListEventArgs) Handles btnDelScnYes.Click
Dim scn As dat.Iteration = New dat.Iteration(e.iterationID, SessUserID)
scn.DeleteIteration()
Response.Redirect("Calibration.aspx")
End Sub
Not sure if this is useful, but just some info: My page have a list of iterations. there are several columns to this table. when the last column is clicked, the modal popup shows and asks the user if to confirm if he/she wants to delete this iteration which is this code:
Dim scn As dat.Iteration = New dat.Iteration(e.iterationID, SessUserID)
scn.DeleteIteration()
so i'm trying to get the funtion to be called, but it's not working. when you click "OK" nothing happens. when i debug it and trace the logic it doesn't even go into the above VB subroutine.

I have seen that ASP .Net Code Behind files are really slow. I have used local web services which i call from jquery ajax function and they are fast. But i am still confused? Should i display dynamic data from code behind or web services?
I let my web service return a JSON Object and i assign relevant elements from that JSON object to different html elements like (image, div etc.)

When trying to edit the word before the delimiter the service method is not even called in IE but works fine in Chrome.
As an example, while '$' is set as a delimiter;
$csAux.Value$csNeedsPO.Valu
Now, editting the word
csNeedsPO => the autocomplete populates as expected succesfully.
csAux.Value => doesnT trigger the method in the background.

I am writing my first AJAX enabled page. Basically I am trying to expand out the lines of a Purchase Order (PO) using our company database. What I want to do is have a button that will that will call on a javascript to update a div field with a table for the PO lines of that PO and at the same time change the function that is called by the button to a function that will collapse the list. How would i do this?
I have tried the line in javascript:
document.getElementById('Button ID').onclick=CollapsePOLines(POID)
However it doesnt seem to change the onclick event for that button, it doesnt throw an error though.

I have an ASP.NET (3.5) web page which calls a few web methods (SOAP based) using jQuery's .ajax method. The web methods implement 'ScriptMethod' attribute and return JSON data. The web service file (asmx) is local to the same project.
I noticed these web methods execute synchronously on the server which means they run sequentially and affect performance negatively, some methods are waiting, when some of them are slow.
I read this article and I am not sure if I understand that WebMethods which implement Scriptmethod can run synchronously only (they implement IHttpHandler not IHttpAsyncHandler).
If this is true, I might have to change the design. I am looking for other designs, maybe like using WCF, where the browser can call webmethods using JavaScript and the web methods run asynchronously on the server.

How do I protect a webservice if it is called from ajax ?
Update: I realize that my question didn't reflect what I intended to ask. I don't want user to be able to do the request by pointing to it with its webbrowser but only in the context of my app.

I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.

I have an ASPX page which hosts a Custom Control. That custom control needs to call an ASMX web service. I would use a PageMethod, if the fact that I'm calling from within a Custom Control didn't preclude that. I'm looking for some guidance on the most effective way to try and lock down the ASMX call such that it will only succeed for my users calling it from my ASPX page - and not for anyone trying to call it from elsewhere. I've seen various ideas around session variables and so on.

I'm doing a gridview with an object datasource:
List<MyObject> TheSource = a linq query At some point, I have
MyGridview.DataSource = TheSource;
MyGridview.Databind();
and an OnRowDataBound event handler that's tied to the databinding. In that event handler, how do you make column 2 contain 2 objects from TheSource. For instance, in the TheSource, there is a variable for FirstName and another one for LastName. Column 2 needs to contain both the first and last name in the same cell.

I have been attempting to Databind a control's ID inside of a datalist all day.
Does anyone know if that is possible?
I need to databind a LinkButton's ID, but have run into this error:
<dx:ASPxHyperLink ID='<%#Eval("name") %>' runat="server" Text='<%#Eval("Text") %>' />
Parser Error Message:
The ID property of a control can only be set using the ID attribute in the tag and a simple value. Example: <asp:Button runat="server" id="Button1" />
I can use any html control that will allow me to display databound text and databound ID
