C# - How To Handle The Click Event Of A Button In A Custom ITemplate Control
Feb 28, 2011I've created a custom control in ASP.NET for showing a pop-up message box. In my MessageBox class, I have a Content property as ITemplate like the following:
[PersistenceMode(PersistenceMode.InnerProperty)]
[TemplateContainer(typeof(MessageBoxContent))]
[TemplateInstance(TemplateInstance.Single)]
public ITemplate Content { get; set; }
I used my custom control in my page like this:
<cc1:MessageBox ID="MessageBox1" runat="server">
<Content>
<asp:Button Text="Save" runat="server" ID="B_Save" />
</Content>
</cc1:MessageBox>
Even I set the the Content property's TemplateInstance to Single, I still can't have access to the Button control.
All I want to do is to handle the click event of the button. When I assign an event handler to the button control and run the project, it throws a NullReferenceException.
Custom Server Controls :: Click Event Not Firing In Rendered Control
Apr 14, 2010I have a custom control that renders a button. I'm trying to attach a server click event but it isn't firing. My code is:
protected override void CreateChildControls()
{
btnRangeGo = new Button();
btnRangeGo.CssClass = "divSearchGo";
btnRangeGo.Text = Resources.CORE_Resource.S0C29; // Go
btnRangeGo.Click += new EventHandler(btnRangeGo_Click);
// Tried with no luck:
// this.Controls.Add(btnRangeGo); // Needed so OnClick gets registered
// Page.Controls.Add(btnRangeGo); // Needed so OnClick gets registered
}
private void btnRangeGo_Click(object sender, EventArgs e)
{
int i = 1;
}
OnRender:
btnRangeGo.RenderControl(writer);
Custom Server Controls :: Trigger Click Event In Composite Control?
May 10, 2010My CompositeControl creates dinamically several RadioButtonLists according to the DataSource information. These controls are added to the Controls list and rendered in CreateChildControls event.
I need to create a LinkButton that clear a specific RadioButtonList selection and do a postback, to load the DataSource information again (some selections changes the data that need to be loaded from the database). For each RadioButtonList, I've put a LinkButton and assigned the Click Event to a method inside the same CompositeControl, to do the RadioButtonList cleaning.
Unfortunatelly, the LinkButton doesn't trigger the Click Event. In HTML code, the link has the "onclick" attribute setted with the asp.net event, but when clicked, nothing happens.
Button Click Event Still Firing Even Through Custom Server-side Validation Fails?
May 27, 2010I am having a problem where my button click event is still firing even though my custom server-side validation is set to args.IsValid = false. I am debugging through the code and the validation is definitely being fired before the button click, and args.IsValid is definitely being set to false once the custom validation takes place, but it always makes its way to the button click event afterwards.

Feb 10, 2011I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

Forms Data Controls :: Database Updates But Gridview Doesn't After Custom Button Click Event?
Feb 8, 2010So I followed Scot Mitchell's tutorial from asp.net/learn on adding a checkbox column to be able to select multiple entries and delete them with the click of a button. When I make my selection and click the button it works on the database end, as the desired entries are deleted. However, the entries remain on the page after it reloads. if I refresh the page it's updated properly but I'd like it to automatically update after the button is clicked.
Also, I tried his method for adding check/uncheck all buttons to the top of the gridview and they don't seem to be working either.
Here's the code behinf from the gridview page:

Force JQuery Click Event To Proceed Any Control Click Event On Page?

Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this.

C# - Writing Custom Controls?

Http - Writing A Custom NTLM Challenge/response In C#?
Jan 18, 2011I know that you can enable NTLM authentication in an ASP.Net app using:
<authentication mode="Windows" />
However - I need to handle Forms, HTTP and other custom authentications in the same app, so ASP.Net's limited built-in support is no use.
The NTLM handshake should be fairly simple:
Request - [unauthenticated - no user info passed]
Response - 401 Unauthorized
WWW-Authenticate: NTLM
Request - Authorization: NTLM <base64-encoded type-1-message>
[code]...
I need to parse type-1 and type-3 messages and generate a type-2 message.
The structure for those messages is well documented but fairly complex - it seems very messy to write my own message generators and parsers. I think the methods to read and write these messages should already be in .Net, but I haven't been able to find them.
Custom HTTPModule - How To Tell When Writing Last Block Of HTML In Write Method
Jul 2, 2010I have written an Http Module that hooks onto the Response.Filter property of the current request and does various replacements within the HTML before it is sent to the client.All the work is done in the Write method which is overriding Write in the base class Stream.
The Write method is called multiple times for a single response - the HTML seems to be written to the output stream in chunks. My problem is that I don't have an efficient & reliable way of telling if the current chunk is the last chunk (for why I want to know this see below). The only way I have come up with is to check if the chunk contains a closing html tag - but this is not very efficient or reliable.
The reason this is needed is that the module must add the "Refresh" HTTP header to the response, but only if the HTML fulfills certain conditions (and there are certain conditions that mean the header must not be added). So, only when the last chunk has been seen does the code know if the header can be added or not. So, I either need a test for the last chunk, or on each call to Write I add the header if the current block of HTML passes the test (if it has not already been added) or remove the header if the current block of HTML fails the test (if it has already been added).
So, is there a better way to test for the last chuck OR is there a way to test for a particular header being in the response and delete it (there doesn't seem to be a way to do this - only to append headers)?

Sep 21, 2010I've created 2 web user controls. A = User control that displays an image, and B is the user control that hosts A.

How do I get A to just display the image from the byte stream? It doesn't come from a database, it's an image I created on the fly.

My problem is how to create a link on the selecond level rows that posts back with custom data.
Custom Server Controls :: Button Triggering An Event In A Custom Webcontrol?
Nov 16, 2010I built a webcontrol showing a complex user interface with a lot of javascript. Basically my webcontrol is similar to : [URL]
Now that most the user interface is working properly, I'm stuck with the following issue: I want to add a button (html button tag) which has to trigger an event. I have been able to declare the event, the event args, the delegate,etc. The page using my control may assign a handler and that handler is called correctly when I explicitely call OnServerControlClick (The name I gave to the event). I cannot make the link between the button in the user interface and the event in the webcontrol source code. When the button is clicked, I get an error message saying a dangerous Request.Form value has been detected.
Web Forms :: Binding A Click Events Validation To Whether Another Click Event Has Happened?
Jan 7, 2011I've been searching a little bit to try and find the answer to this problem. As of right now another person I work with has designed a wizard step with an upload button in part of it. After the person clicks the browse button and selects their file a validation statement comes up saying, "Please click 'upload and continue' or clear the field" and then is supposed to disable the continue button until this is done. He started by adding a RegularExpressionValidator and found it did not solve his problem.
Now that he's out today we're working on trying to solve this and my first though is to actually use a custom validator instead and have it call a function in the back-code for validation which checks to see if the "Upload" click-event has happened. Is there an easy way of verifying whether or not a click-event has occurred. Basically my conditional is shown in the pseudo-code below...

View 6 RepliesC# - Button Event Handlers Do Not Fire On The First Click But On The Second Click After A PostBack
May 4, 2010Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.
Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.
I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.
Example of Button Definition (within GetAdministrationInterface)
