This should be an easy solution but I get stuck with it and hope I can get some advice/guidance from you:I have a simple aspx page with a Paypal button in it. The code shows in .aspx page:
[Code]....
I have a login control inside a page.
I have created a method like this:
[code]...
how do I fire the Authenticate event of the Login on Page_Load or at least how can call Login1_Authenticate(...) with the correct eventargs so that the e.Authenticated of the login control be set to true?
I have one Datagrid with Footer. Footer Row Contains Input fields with one Button to add New Values. I have button click event but not getting fires. my code follows:
[code]....
Every time we click on a button. the Page_Load will fire first.
For my case, I have some controls added programmatically to the GridView, when the button click, the Page_Load event fire, my controls just go away.
I have write the code in .Net. When I click the Buttun then fired below event.
protected void ddldesignation_SelectedIndexChanged(object sender, EventArgs e)
{
Code.
}
I have a button which has a click event but its not firing on the first click. I suspect its something to do with that i am in dropdown box control so when i click the Button the event for the dropdown box occurs (textChanged) but it forgets about the click event
Of course if i click it a second time it works.
Or if i click somewhere else first so that the event TextChange occurs and then click the Button the first time it executes..
Is this normal and what are more workarounds if any?
basically the TextChange event must fire but the button click event must fire as well.
All the events i am talking about are ASP.NET events.
here is some examples of the events i am using - both the button and dropdown
uxGetData is a button and uxToDate is a dropdown box

I am trying to fire one event out of two avalible events based on a check box selectoin, I have already registered the two events in the page_load() and i check if the check box is checked (checkbox is located within a gridview) then i un-register one of the events and just keep one events registered as following(Only relative part is shown):

I am trying to fire one event only based on the checkbox selection. I tryed to debug and noticed that, in fact, both evetns always get fired starting first with Button_SessionStartOrEnd_StartSessino and then Button_SessionStartOrEnd_EndSessino. So how can i fire one event only? please note that my code to check if the ckeckbox is checked within the girdview works fine.
I have a very common problem with asp.net . I have designed a webpage that performs some action on its load event but whenever a user clicks on back button those actions are not performed as Page_Load event is not called.I have searched a lot of forums but wasn't able to get a exact answer. All I was able to know that it was happening due to cache memory maintained by browsers. I don't want to delete that cache. I want browser to work in normal way.
View 3 RepliesI'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 have a modal formview with insertitemtemplate. I have to click the insert button twice to fire the event.
But if I do not insert any values, only one click is required and the validationgroup fires. But if I enter all valid values, I need to click twice and the event does not fire during the first click. But I need CausesValidation = false because to required field validators.
How to avoid two clicks to fire the event if the formview is valid

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 2 RepliesHere'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.

i 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?

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?
