Why does my event handler need 2 button clicks to work?

Posted By:      Posted Date: October 21, 2010    Points: 0   Category :SharePoint

I've created a Visual WebPart in 2010 with two buttons.

One works as it should (it updates a database and puts a success string in a label) with no problems

One gets a dataset and populates some labels and textboxes (using a Page.DataBind).

With this button, I need to click it twice (not exactly a double click) - once, let it post back and then click again

If I copy the exact markup and code to a test ASPX project, it all works perfectly as it should.

I've tried both a DataSet and a DataReader - code to populate controls is like the following:


Then, after all, I follow by a Page.DataBind
Within reader.read:
lblSerialNumber.Text = myReader["Serial Number"].ToString();

Does anyone know what could cause this?

Button click event handler firing twice

I noticed today that button click event handlers are firing twice for me in some cases when the button is inside an UpdatePanel -- but only in Firefox.  I'm wondering if this might have to do with the Firefox update that came out today because I never noticed this problem until today.  Has anyone else run into this problem?

Creating Event Handler in Code behind


Hi, so I have a control that is created in the code behind and generates fine but I can't figure out how to create an event handler for it.  I've found plenty of examples for it in C sharp, but none of them seem to apply to VB.  What I want to do is essentially this:

myDropDownList.SelectedIndexChanged = "Event to do here"

but it doesn't seem to work for me.

Any suggestions are appreciated.

C++ at Work: Event Programming, Part 2


Last month I answered a question about implementing native events in C++ (see C++ At Work: Event Programming). I discussed events in general and showed how to use an interface to define event handlers for your class that clients must implement to handle events.

want to launch modal Popup from created User Event handler




I have a create user wizard on my page and in the event handler (Created User) I get extra information from the user

via textboxes within the aspx etc.


I then do a response.redirect to another page.

What I want to happen is this


When the CreatedUser Event is fired, I  want a Modal Popup to show up with a message Processing your registration.

once the registration code is processed it will close and the users get redirected.


On my ASPX I have the Modal PopUp and a Panel.

In the code behind in the handler I put ModalPop.show()


but this does not work.


thanks for any suggestions



file upload in Create User Wizard Created User event with UpdatePanel Tag wont work?



In my Create User Wizard1 Created User Wizard Event, I am collecting extra information from text boxes and allowing

the user to uplad a file.



I have put the Submit button within an Update Panel Tag but since I have done this it does not work.

Is there a way round it. In this situation would you use a trigger.?


<br />

  <asp:UpdatePanel ID="UpdatePanel2" runat="server">

  <asp:Button ID="StepNextButton" runat="server"  CommandName="MoveNext"  align="middle"
                                            Text="Submit my Profile" />

InfoPath Workflow Task Form "Loading" event handler only being called after App Pool recycled.


I have a Workflow that is using an InfoPath task form.  In the "FormEvents_Loading" method event handler I have some code that needs to run each time the form is opened.   I recycle the App Pool and open the form the code runs perfectly, but if I close and try to re-open the form the code is not run at all.  I can then recycle the App Pool again and on the next load the code executes just fine.   The code that is supposed to be run is a very simple statement to set a field value, so I don't think it is interfering.

Does anyone know what this might be?

How to get Click event to work with checkbox


I am new to ASP.Net and I'm having trouble figuring out what needs to be where in my code.  I have a webform with 2 listboxes and 2 checkboxes... When I check checkbox1 I want listbox1 to be disabled and checkbox2 to be disabled.  Similarly, when I check checkbox2 I want listbox2 to be disabled and checkbox1 to be disabled.  The code does not show any errors; however, when I run the Page everything appears as it is supposed to but when I check the boxes, nothing happens.  What am I missing that will link the code on the .aspx.vb page to the objects on the .aspx page and make them work together?

Here is my code for Page1.aspx.vb:

Public Class LCPage1
    Inherits System.Web.UI.Page

    Protected Sub AllClients_Click(ByVal sender As ObjectByVal e 

Catch button click event in different .aspx page.


I have a button which starts processing.
I want that when ever a button is click from page1.aspx .. a count down timer should start and displayed on page2.aspx.
I am thinking of using iframe to join 2 pages.

Please let me know your suggestions.
