Web Forms :: Button_Click Event Is Firing Twice?
Jan 6, 2011
I've stepped through the code and verified this action. It gets to the end sub and just loops again. Also does it on the production server in IE and Chome (that's all I've tried). Here is the button definition on the actual ASP page:
[Code]....
It goes through the code, sends me an email, gets to End Sub, then loops right back to the top of the sub and goes through the whole thing again, sending me a duplicate email, then exiting normally and sending them to the About page. This is the only code in the aspx.vb besides the class def and inherits statement.

I have a page with in a master page. This page has a user control with a text box and a button. I also have another button on the page. As the page first loads the button_click event on both the controls does not fire when clicking the buttons. I also have an event on the enter key on the text box. This event fires which causes a post back. After post back now my button_click event fire. The button_click event does not fire on the first page_load.

I have a ASPX Page that contains several user controls, which are loaded dynamically after user interaction.
On one of ascx I have a hidden button that is being clicked on some user actions (via button.click()), which works fine on 1st page load. But after the form is being submitted once, the other ascx is loaded. There if user clicks the back button and resubmits the 1st form (again via button.click()), button_clicked event on server does not fire again.

I have a detailsview that is listing a users membership data. userid, username etc... I have the info in template fields. Basically I have also created a button named "Delete User" at the bottom of the page outside of the detailsview. (detailsview is only displaying one user's data). When the button_click event is called I would like to delete the user using the command
[Code]....
Where username is a string I pass through from the detailsview. I am using VB and can't seem to find a way to bring the username value over from the detailsview into the button_click event.

I want to be able to show the record that was just inserted after add_button_click event. I run the insert from mycommand and then set mycommand2 to run the read to populate a details view. I have a feeling I am going about this the wrong way. The insert fires correctly but the details view does not populate.

I'm going nuts here.. This is what i like to do: When i click my serverbutton i want a fade message to show and then execute as usual all the servercode (db insert and more) i have in my button_click event in code behind. The fade effect works, but the servercode never executes. I don't know how many guides i have tried but it seems impossible to achieve this. I just want to fire the the code in my click_event. I really hope someone of you can point me in the right direction.
This is my fade code:

1. Does the whole page load everytime there is an event(Button_Click)?2. Can an iframe refresh(page load) without having to load the whole page it is in?

I read so many post which say if i need to catch the button event on the modal popup extender, i need to use javascript. But when it comes to my requirement I get confused.
I open a data entry form which contains several textboxes, drop down lists, validator controls and 3 buttons (viz. SAVE, SAVE & CONTINUE and CANCEL) on the modal popup. The requirement is that :
1. When the SAVE button is clicked the data in the different controls must be inserted into the database and the modal Popup must disappear.
2. When SAVE & CONTINUE button is clicked the data in the controls must be inserted into the database and the modal popup must be ready for the other with clear controls.
3. When CANCEL button is clicked the modal popup must simply be disappear.

I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.

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.

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.

I have a two web forms with griviews that are bound to SQL through the same query in a class. Both have the same columns and footers. Both have a checkbox control in each grid row. The checkboxes on each form have OnCheckChanged event handlers that I put in the code behind. In fact, the html code is almost the same on both forms, and the OnCheckChanged code is exactly the same except for the fact that I have named them differently. AutoPostBack is true for both checkbox controls in the gridviews. One works, the other doesn't. The difference between the two is that the gridview row checkboxes that don't work are burried in a MultiView. Could that be why the codebehind event handler doesn't fire? Here is the html for the column:

Here is the html for the header of the gridview:

Here is the codebehind:

I have an asp.net 2.0 c# site.
In that site, I have a drop down list which allows the user to select from a number of forms with AutoPostBack set to true. I have a OnSelectedIndexChanged event on the dropdown which loads the correct control depending on which option is selected. See below:
[Code]....
Now, that works correctly and loads the form as expected, but the server side onclick event within each ascx control now doesn't work. Is there some problem with button events when controls are added this way? When I add the control in manually to the page it works fine.

i'm creating and adding checkbox in my code behind to a parent control.
autopost back is true, it's posting back on being checked, but i'm not sure how to capture the fact that it's checked before I recreate/add it to the parent control again.
i can search all controls and find it prior to re adding it to the parent, but it never shows checked...
i have a checkchanged event on it that never fires, thing it's a flow/view state issue, but not sure how to reslove...

I added some code to Global.asax on app start and I had to copy same project on a different machine and suddenly Global.asax file's event didn't fire. After doing lot of googling and trying many things I deleted the existing Global.asax and added a new one and then tested it. And I was surprised that it started to work again. so I would like to know what caused that previous Global.asax not to work?

I am losing User.Identity.Name unexpectedly, resulting in "out of the blue" redirects to Login.aspx.
This seems to happen randomly, often in the first few minutes after a user login.
To track this down I setup a Trace text file and append an entry to it when any page loads. I also write an entry from Session_OnStart event and Session_OnEnd event in Global.aspx. When user logs out, I call Session.Abandon, which should fire the Session_OnEnd event, and cause a log entry. However, this is not happening. It seems that Session.Abandon is not firing Session_OnEnd, inconsistent with info inhttp://msdn.microsoft.com/en-us/library/ms178583.aspx
Session_OnStart does seem to be firing as expected.
