Web Forms :: User Control Click Event Doesn't Fire?
Mar 8, 2010
A little confused on something. I have a User Control in a master page. In the User Control there are image buttons. when I try to wire any click event even to say update a label in the User Control itself, nothing gets updated.
It is as if the postback is not handled at all.
What I want to do is click the image button in the User Control and then change a value in the master page. This could happen a few ways but for example it could update a public property or a control itself like a textbox or label.

I don't understand because the click event doesn't fire in ascx control nested in masterpage.
The scenario is:
In Page Pre-Init i load a particular MasterPage, one of these have a ascx control with LogOff Button.
The ascx is showed correctly but doesn't fire the button click event that allow me to logoff.
I haven't load the control programmatically but directly in masterpage:

I've run into a problem with one of my web sites and I am having trouble figuring out the problem and a good solution. This is my scenario: I have a user control that displays a slideshow with images and some text that changes every fifteen seconds. To do this, I have an update panel that contains a timer control with an interval of 15000. It calls a method called slideshowTimer_Tick in the codebehind. The web page that contains this user control is a relatively simple page; no update panels or timers, just divs.
The problem I have is that if I have two of these user controls on the page, the tick event only fires for the first control. It never fires for the second control, although the control is full initialized otherwise.

I have a datalist that loops thru cart items. Within the datalist template I call a user control that has a small form that gets repeated for each item. When this control is called outside of the datalist, the form submits fine, but when called within the datalist the button has no event action. I've tried adding an event handler to ItemDataBound of the datalist, but still no event action. How can I get my form to submit?

I am fairly new to the asp.net and experimenting with it to learn the page life cycle. Here is a problem that I have been unable to resolve for past few days.I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow. First user control is loaded on application start up. It has a "continue" button. Continue button click loads the Second user control that has two buttons - "Back" and "Submit". Obviously the "Back" button should load the first user control again and Submit button should submit the form data.

Obviously the "Back" button should load the first user control again and Submit button should submit the form data. Pretty simple.
The problem is that the command button event handler that I have on the second user control is not firing the first time. (I have one event handler for both buttons). The load event of the user control fires but then it ignores the button click. If I click it again, then it fires. I re-load the controls on the page in every page_load. Here is some relevent code:
AddPlayer.aspx:
[Code]....
The page_Load fires every time but "CommandBtn_Click" doesn't fire after the first click. I have to do it click it again. It doesn't matter which order I click the buttons.

I have a webdayview control (Infragistics proprietary ASP.net control) on my page. On the aspx source I've inserted some javascript (webdayview_click - clientside click event) that calls a webmethod in the codebehind. This seems to work fine, but when I
insert this webdayview control into a user control and move the corresponding javascript into the aspx of the user control, it doesn't work. I can't even insert a breakpoint into the javascript function to debug it. Is there a way to make it work? I want to enable the click event of the webdayview control so that when I click on it, the javascript function calls the webmethod. Here's my code (remember it is inside a user control):

I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)

I have a small website where I want to display a confirmation dialog after clicking on a button.
When you click the confirmButton the dialog appears. Then you can choose between Yes or No to either continue with the PostBack or to return.
Problem: The first time you get into the site all works fine. But after you click Yes to continue with the PostBack, no click event will be triggered anymore.
Here is some code.

I have a button like this:
<asp:Button ID="btnSave" runat="server" ClientIDMode="Static" Text="Save" OnClientClick="return ConfirmSave();" OnClick="btnSave_Click" />
If I write my client function like the following, it works as expected:
function ConfirmSave()
{
return confirm('Confirm?');
}
But I should check, inside the function, for the confirm result, like this:
function ConfirmSave()
{
if (Page_ClientValidate('validationGroup'))
{
var conf = confirm("Confirm?");
if (conf)
{
$('#btnSave').attr('disabled', 'disabled');
}
return conf;
}
else
return false;
}
Doing this, the page postback but the server click event doesn't fire.

I am building a website whereby people, before checking out of the shopping cart (and transferring to the payment iframe) can select which items from the shopping cart list to delete. The results from the shopping card are listed in a Repeater control. There is a Button in the Repeater which deletes a record from the database (used LINQ to SQL to do that.)
THe problem is that the ItemCommand event doesn't fire when i click the button. I tried 'response.write(test)' and it still would not work. It is as if the repeater cannot interact with the commands. It does render the results tho.
Here's the code:

I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false.
Page code -
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %>
<act:ToolkitScriptManager runat="server" ID="ScriptManager1" />
<asp:UpdatePanel runat="server" ID="upnlFileUpload">
<ContentTemplate>
<asp:Button runat="server" ID="btnShowUpload" Text="Show Upload" />
<div runat="server" id="divUpload" visible="false">

I have a need to improve the asthetics of the standard buttons .net churns out. I am fully aware of how to do this using css but I can only really style the button if I add a span element inside the button. Luckily the link button allows this so I have got the following which for usability i have put inside a user control.
<linkbutton><label>button text</label></linkbutton>
I have exposed elements so that I can set values from within my aspx.cs page, these are text, command name, command argument, ccc class etc.
As it is a generic control, I have added OnCommand='Button_Click" which fires the event in the control itself. The Button_Click event calls a method ButtonControls passing associated command name and arguments across. ButtonControls uses the name to call the appropriate function.
As these are all very generic buttons, so far so good, but I have a need to trigger button events that may not be generic i.e on a control I have buttons that do something very specific to that control. I also have a requirement to call functions which relate to specific controls on the aspx page. I have created a user control which encapsulates the link button control.
Click triggers > Button_Click > ButtonControls > MethodToCall
sometimes I don't want to call Button_Click just an event on the aspx page itself rather than my generic button handler.

I am creating nested accordion using the object model and have created buttons in the inner accordion's accordion pane. The buttons look great but issue is that the buttons does not fire thier click event. They just do the postback of the page and ignore the event.
I want to show a pop-upextender on the pre_init event but all my panes are added dynamically so it does not give any rows.

I have a 2 part question for web user controls: 1. I want to have an event fire in my user control, but have it be consumed by the parent page, like:
<asp1:Object id="objectMain" runat="server" OnClick="Click" />
Is it possible to do this? Or do I need to make a server control for this functionality? I have it being able to be set in the Page_Init, but I'd like to make it as similar to actual controls as possible. Also, if it is possible to access via the Events section under Properties, that would be good and 2. I am trying to register the web user control as an AsyncPostbackTrigger for another UpdatePanel. With the previous question in mind, is it also possible to set this via the GUI, or does this need to be set programmatically as well?

I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.

im using an update panel and my web form consists of textboxs and combo box, my problem is that when i click the button save for the first time, my page simply postbacks and the event save wouldnt fire, click it the second time and poof save will execute.. I notice that it is caused by my dropdown box and textbox autopostback function, i need to set this to true since i need to execute another function that will disable the dropdown when the textbox is filled and vice versa,set this to false and save will function normally..any ideas how to fix this?
here is the code for that.
<asp:DropDownList
ID="ddNewLocation"
runat="server"
Width="95%"
AutoPostBack="true"
AppendDataBoundItems="True"
onselectedindexchanged="ddNewLocation_SelectedIndexChanged">
<asp:TextBox
ID="txtNewLocation"
runat="server"
Width="90%"
AutoPostBack="true"
ontextchanged="txtNewLocation_TextChanged"></asp:TextBox>
