C# - When Should Page.Header.DataBind Be Called
Oct 7, 2010
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.

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 have a Tab Container that I would like to be able to add a star (*) at the end of the tab header text when there are NEW Users to be approved by the Site Administrator. By default meaning that is what I typed in designer mode is "Users Waiting Approval", but when I load the page I run a routine to see if there are and new users requesting access and at that point durning the page load I would like to change the tab from "Users Waiting Approval" to "Users Waiting Approval *" with the star at the end (*). How can I update this tab header text durning the page load event? Is there some javascript function I can call like set_HeaderText?

1) I know there are lots of web sites that describe in what order events are called during the Asp.Net page life-cycle. But is there also a tool, perhaps Reflector, that would enable me to figure out by myself in what order are ALL the page's events and their event handlers called during the page's life cycle? 2) Would you say that trying to figure out exactly what is going on under the hood is a good idea or a waste of time? To clarify - I'd like to figure out exactly what is going on when a control tree is build - thus all the method calls, all the events called etc needed for control tree to be build ( I imagine there are hundreds or perhaps thousands lines of code written just for building a control tree).

Assuming i have two dropdownlists namely: dropdownlistA and dropdownlistB. at page load, i bind values to dropdownlistA. however, depending on the value selected or displayed in dropdownlistA, i want to bind data to dropdownlistB.
Currently, i can bind data to dropdownlistA alright and i already have the required dataset and datatable bind data to dropdownlist. However, dropdownlistB does not bind at page load since the criteria for filling the dataset to bind dropdownlistB (which is the value of dropdownlistA) is not selected. how can i make this wwork.
I am currently considered if this might work. If i were to call the databind for dropdownlistA in a different declared method besides its binding in page load, and select the value from bind in the declared method, would any value be selected?
For example:
In during page load, i call the a method that returns dataset values which i bind to dropdownlistA(caseIDDropDownList). then i call another method (CreateexhibitDataSet()) which contains the dataset values for binding dropdownlistB(exhibitDropDownList). however, i need to define a criteria in the CreateExhibitDataset() method which i will use to generate the dataset values to bind dropdownlistB. if i were to call for the data bind of dropdownlistA(caseIDDropdownList) again in the CreateExhibitDataset() method and pick the value in the dropdown list, would i get any values?
How can i work around this to bind both dropdownlists on page load?

I am trying to implement a custom HTTPModule for ASP.NET. I have a very simple html page with an image in it and an HTTPModule that hooks into the BeginRequest event. When I debug with Visual Studio's dev web server, my module is called twice: one for the initial page request, then once for the image request. This is what I expected. However, when I deploy my application to IIS, the module is only being called once for the page request.

CommandName="<%# Container.ItemIndex %>"
when i click the button, i'm expecting commandname to = 0, then 1, then 2, etc, as the datalist progresses, and i'm using that value in the button click's c#but i'm getting this error, i'm pretty sure i'm using this exact setup on another page and i have no problems, any idea what's going on?Server Error in '/' Application.

I am using a wizard control in which I have a next button that has causes validation = true. I also have a checkbox that when changed, in the event handler, I set causes validation = false for the next button. When that button is clicked - I get the following:
Page.IsValid cannot be called before validation has taken place. It should be queried in the event handler for a control that has CausesValidation.
Here is the code:
protected void chk_CheckChanged(object sender, EventArgs e)
{
CheckBox chk = (CheckBox)sender;
ImageButton ibtnStepNext = (ImageButton)(this.WizardSummaryTemplate.CustomNavigationTemplateContainer.FindControl("StepNextButton"));
ibtnStepNext.CausesValidation = (!chk.Checked);
}
What would be the recommended solution to disabling validation for the next button so I don't see this error?

I'm developing a custom URL Rewriter for a ASP.Net 3.5 project. This rewriter is not functionally different than most rewriters out there, the only difference being that the friendly URL collection is not loaded from a web.config file -- it's coming from a database instead. I made the naive assumption that it would be easy to develop a custom rewriter module from scratch, but now I know the mess I put myself in. I digress; let's go straight to the technical issues.
While testing the rewriter, I set up a friendly url that would take the user to a web form. Postbacks from this form should not alter the friendly address, as anyone would expect, sohttp://my.web.site/app_root/FriendlyURL is always rewritten asttp://my.web.site/app_root/not_friendly/form.aspxThings are fine when the browser first loads the FriendlyURL. The page comes up and is completely functional. However, when the form is posted back to the server, the page simply reloads but, at server-side, IsPostBack is false. It's like F5 was hit, except that a HTTP POST had indeed occurred.Unsurprisingly, when the interaction occurs through the "unfriendly" URL, the POST action triggers the postback as expected. This evidence suggests that HttpContext.RewritePath is somehow messing with the page lifecycle in a way that it loses sense of the postback operation.

I want to use SDelete after some code is run on an asp.net page. SDelete is a command line tool. My specific question is has anyone been able to run this SDelete from an asp.net page? More generic question would be, how do you run a command line utility from an asp.net page?

I'm trying to add html text to some repeater items during DataBind, but the html text isn't parsed into controls it just displays as text. If I copy the text and just add it to the asp.net page it works fine so I know my syntax is fine. So is there a way to dynamically add more html text during the data-bind phase?

I have an image control that puts user's photo in it. Once it's loaded, I resize it using the javascript.But the thing is, when the page is loading, the image gets really big, then shrinks down being called by the javascript. Is there a way for me to pre-load the image before displaying it? I do'nt want to set the image control's width and height to fixed pixels at this point.

But at RenderControl line, I get following Error:
RegisterForEventValidation can only be called during Render()
Is there a way to resolve it? At many forums I found set the EnableEventValidation=false in page directive. But this is a dynamic page and has no directive. Further this property is not available when I browse mypage properties.

I use a commercial web application that has the ability to use web triggers in order to do additional validation prior to saving its forms. The commercial web application simply makes a request out to whatever asp, php, etc. code that you've written... and in the case of asp.net I've validated forms by pulling variables off of the page.request object and then passed back a success/fail message to the commercial app using JSON.
I would like to use asp.net to display a modal popup control when called, in order to display some options. Because I would be triggering this code from a commercial web app, I'm wondering how I can display the popup control on top of the requesting page? The code I've currently written displays a blank page with my popup control on it. Is it possible for me to display ONLY the popup control when called from another website?

I just discover why some validation is working bad on some of my forms: the button click event is being called before page load.
What I need for good is (I consider this is a normal cycle of events):
The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results
But this is what I get (BAD):
The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesn´t loads again and I cant see the results, so my client cant know what happened on the server side
This is how I tried to implement this:

Can a required field validator be called from the code behind page?We have several check boxes and some of them require the user to enter a date, but not all of them.(This is not a checkbox list, but individual checkboxes).Any 1 of 6 different checkboxes selected makes a txtBox visible for users to enter a date.If they don't select one of these checkBoxes which require a date - it doesn't matter, the form will still be valid.I don't think validation groups can work here so looking towards doing through .vbHere's the existing code:
