Here's an odd one that I've never seen before. Only on IIS, not in Cassini but in all web browsers I have a button that posts back and the page_load event fires, but the actual button click event doesn't fire. there is no re-writing of the page or anything else happening.
View 4 RepliesIn my project when i click any button or linkbutton, it doesnt fire any event or doesnt postback.
It was working fine but now it hv problem like this.
I think i have changed some settings by mistake.
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've been looking at google for the past few hours, trying to find an issue to a apparently simple problem. I have a UserControl named RolloverLink that basically contains a asp:LinkButton and a <img /> . I tried setting the OnClick handler like this:
[code]....
I put a breakpoint in the propagate method, but it doesnt stop there. The page does post back (it flashes), but the event doesn't get called.
Here's how my code behind looks like:

I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).
we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.
here is what I'm doing:

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.
View 3 Repliesi have a JQuery ui dialog box that opens up as a contact form when a link is clicked, which works fine, my problem is trying to submit the information.
When you click the send button it fires a button click event of another asp:button ive got hidden on the page...
the post back event fires and the page reloads but the asp:button click event doesn't not fire?
Heres my code:
asp:Button is as follows:
Code:
[code]....
The following code is my ASP.NET page :
<MdsMenu:MenuItem Text="Button" Href="#">
<asp:Button ID="Button1" runat="server" Text="Button 01" OnClick="Button_Click" />
<asp:Button ID="Button2" runat="server" Text="Button 02" OnClick="Button_Click" />
</MdsMenu:MenuItem>
I don't know why Button_Click event doesn't fire!
protected void Button_Click(object sender, EventArgs e)
{
Button senderButton = sender as Button;
Label1.Text = senderButton.ID.ToString();
}
MdsMenu:MenuItem is my custom WebControl. If I insert a Button control out of MdsMenu:MenuItem tag it works well but if I inserted it within MdsMenu:MenuItem tag it doesn't fire the concerned method. What's wrong with my code?

I have a modalpopup that i have opening on a radiobutton selection. That works great, opens when it should and closes when you click cancel. BUT i have the following on my cancel button event that is not firing
[Code]....
I also have a button event for my "OK" button and that works great, but my cancel event doesnt seem to fire or work. Maybe the ClearSelection() is not what i need..
I want to clear the radiobutton if they cancel out of the ModalPopUp so they can make a new selection, since its a required field.
i have two nested gridview inside an update panel. there is a button called btnPhoneEdit inside the child grid view. when the button gets clicked, it do cause partial post back as expected but it fails to invoke btnPhoneEdit_Click.

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. 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 to click twice on button control to fire an event.
View 6 RepliesI have a gridview bound to a sqldatasource with editing enabled. If I click Edit, then either Cancel or Update, the update or cancel occurs and the Edit button reappears. However, I cannot then click the browser's back button without having the Update and Cancel buttons reappear. A second click of the back button takes me to a state where the Edit button shows again, *then* another back button click will take me to the referring page (the one before the one with the gridview on it.) IOW, it looks like the postbacks are cached. How can I prevent this and have the back button go straight to the referring page?
View 4 RepliesTextBox doesn't fire TextChanged Event on IE 8, AutoPostback is true
View 6 RepliesA 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.
Here is my situation: I have a overview of subscriptions that look simple:
Active (bool), ID (int), StartDate (datetime) and MaxUsers (int).
I've put this in a Gridview and it renders nicely.
Now everything is simply in ItemTemplates and are formatted.
Now a new feature: In the Gridview active should be a checkbox and when clicked on it, it should (de)activate the subscription. Or simply said, Active status is updated. Now me being a simpleton thinks:
[Code]....
and the cs:
[Code]....
But! the event doesnt get fired. Now I've searched with google and also through this forum and every time I get the answer: autopostback on true or use commandname. Now for this little feature I think the commandname use in combi with rowbound is overkill for such a little thing.
Now I hope I'm just missing something because this would be really nasty and stupid to make it so complicated. I like the autopostback and oncheckchanged combination because it logical, but why doesnt it work?

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"

AutoPostBack="true"
ontextchanged="txtNewLocation_TextChanged"></asp:TextBox>

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 problem with an asp.net project.I have a default.aspx page with a webusercontrol ascx inside.I have one combobox in my default.aspx and another combobox inside usercontrol.If I fire up my simple application, I noticed that when I select an item in one of the comboboxes, the selectionindexchaged event doesn't fire and le dropdown doesn't close.I have AutoPostBack="True" an all combo.

I've some really strange behaviour with a simple ASP.NET Button. Here's my code:
[Code]....
For some reason the first time I click this button, the code is beeing fired. When login credentials are wrong, a message shows up. THen, the user inserts the right credentials. After clicking the 'cmdLogin' button, nothing happens and the old (wrong) values are beeing filled in inside the textboxes. This behaviour occured to me after switching to ASP.NET 4.0.
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:
