I have the following problem. I have a user control with its own events and procedures. I added this control to a page programmatically. It appears as it should but when you click a button on the user control. the control disappears from the page.
View 6 RepliesI have a submit button which fires some code, the problem is I always have to click the button twice before it fires?
I have a number of dropdowns on my page, a number of other buttons all with unique id's, a postback is always caused on the page before the the submit button is clicked.
Here's some of my code:

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 dont know what happened but none of my buttons or linkbuttons causes a postback anymore. I have dragged a few updatepannels on the page but the linkbutton concerned is not enclosed within an update pannel. when I click it there is just no postback happening anymore. I set the debugger at Page_load but...its not reached. I used firebug to analyse the http requests. there is none. its like those are not considered buttons anymore.
View 5 RepliesI have a LinkButton which fires an OnClick event to update some Labels; however, after the first firing of OnClick, it won't fire again when I click another (or the same) LinkButton which runs the same OnClick event. (It's a list of people, each a LinkButton, and clicking on one brings up their details)
If I leave the page a few minutes, it will work again, almost as if whatever was preventing OnClick firing timed-out. Of course, this won't be any use to the users!
This is my ASP.NET code for the LinkButtons (encapsulated in a DataList):
[Code]....
All the connections work, the data is retrieved, etc, so everything except the OnClick firing works. I've done a search of the internet and the forum, and found this seems to have been a long-standing problem since the first ASP.NET, but there is no solution for ASP.NET 3.5. Does anyone know what causes this, or where I might be going wrong?
OK, been burning up Google and Bing trying to figure out a good solution to this problem, and so far, I feel like I've taken a dive down a rabbit hole - I'm just waiting on the Queen of Hearts and the Mad Hatter to show up. Alice is kinda cute, but unfortunately, she didn't have any good suggestions, either.
Here's the scenario - I have a User Control on a Child Page that has a Master Page assigned. The control is for logging in to the system, so it contains two text boxes, a couple of links to password recovery and registration, and an ImageButton to handle submission of the username/password entered in the text boxes.
Everything works just as expected when the user actually takes the mouse and clicks on the ImageButton control.
Things don't work so well when the user enters a username and password and then presses the Enter/Return key.
While debugging, VS2005 (I know...ugh!) will stop at the LoginButtonClick event, and seems to run the code. Of course, the .Text property of the two input controls was empty, but the Request.Form collection had the values burried within the collection of Keys.
So, a little bit of digging got me to the point where they can login using either the Enter key or clicking on the ImageButton. So, everything seems like it's good, right? Nope, not so fast.
When I enter a username/password combo that's designed to fail authentication, the code will step through setting the error message, etc, but that information never makes it to the point where it's visible to the user.
I'm not seeing any extra postbacks (obvious ones, anyway), but for some reason, when the page goes to redraw when it's in a "failed" state, the notations just simply aren't there.
Below is the code in the User Control that handles the actual authentication routine. All controls, such as the Label with ID "message", are local to the User Control, so I don't think it's a FindControl("message") problem or something similar...just so bizarre that it disappears seeming without reason.

I have page on which I've a login control in which I've a subnit button. The problem is this that when I refresh the that page the submit button or any button that was clicked last before page refresh gets its click event automatically fired.
View 1 RepliesI have an aspx page that is wrapped with an UpdatePanel control, users can post comments and delete them later, when the user clicks the delete for the first time it deletes successfully but if he wants to delete another comment, it works only after two clicks on the button.the delete button is inside a web user control that is added dynamically at run time.

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.
Can i bind and call the user control directly on click event of link button? instead of binding user control in another aspx page and then call it to the masterpage's link button click?
or else can i bind user control in a page lets say default.aspx and then call it in two different master page and show different functionality of it according to the masterpage its getting shown?
I have a user control that displays some database records when I first hit the page. When I click the submit button the page load event fires again, loading the user control again. Then the button click event fires inserting a new row in the database which is not shown on the page because the user control already did its stuff. If I could get the user control to do its stuff after the button click event I could then see the newly inserted row. I can do this by pulling the code out of the button click event and sticking it in the page load event. However, I think that would be bad code flow. How can I get the user control to do its stuff after the button click event has fired?
View 7 RepliesHere is what i am trying to do I have a multiview and two views in it so based on click event the link the views change

apparently they are not firing on first try. The reason i am doing this is the two views have tables with different images to be used in building my menu.
What am i doing wrong? or why is the click event firing on second try?

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 ask for a date, on OnTextChanged event i bind data with a SqlDataSource to a dropdownlist and also bind data to a repeater passing the dropdownlist SelectedIndex (i use SqlDataSource too and ControlParameter to link the dropdownlist and the repeater) On my repeater during the ItemDataBound event i create dynamic dropdownlist controls, my code is :

[Code]....
On the Page_load event of my page i bind the data & recreate the control :
[Code]....
Everything works fine, datas are bound and SelectedIndexes are restore on every postback.
The probem occurs when user change different dropdownlists, if he choose to change the 1st dropdownlist the event is fire (normal), after if he modifies another dropdownlist the event is fire twice, if he modifies a 3rd time the event is fire 3 time etc...
I have a fairly complex master/content page that has several GridViews - each one in its own UpdatePanel. I also have four CustomValidators on the page, each one assigned to a different
ValidationGroup. Two of the CustomValidators are buried inside a HeaderTemplates of a GridView (inside a distinct UpdatePanel). In the EmptyDataTemplate, HeaderTemplate and FooterTemplate of each GridView I have ImageButtons that postback to the server to perform some operation. All the ImageButtons take this form:
[Code]....
When I click on the ImageButtons in one of my GridView's the ImageButtons cause the ServerValidate event of two CustomValidators to fire. The server-side OnClick event of the ImageButton never fires. I have verified that the ImageButton(s) have CausesValidation="False" - what could be causing the validators to fire?
I have a LinkButton within a User Control and it has handled with:
Private Sub LoginLinkLinkButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LoginLinkLinkButton.Click
Response.Redirect("/", True)
End Sub
On certain ASPX pages I would like to handle the click from the page's code behind, opposed to within the user control. How do I override the handle within the control from the parent's code behind page?
Update:
Based on the answer, I have the following no added to the User Control:

The problem is determining the correct syntax for the if line because the above is invalid.
I have a blank user control (child) and during Page_Load i create some text boxes and a button. I also add an event to the button.
I then load that user control dynamically from a placeholder in another usercontrol (parent). Both controls are rendered correctly but when i click on the button, the event isnt fired. how to handle the event?
Child code:
[code].....
If i use the child control directy (ie without the parent the control) the click event is raised and handled nicely. But when i use the parent control, the debugger wont even hit a breakpoint inside UpdateButton_Click().
I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this.
View 1 RepliesI have a user control with contact form and validators, when I add it (user control) to my parent page I get a strange behavior of all buttons within the parent page, Any button I press on the parent page fires the validators of the user control. How can I vallidate the form on my user control only when I press a specific button?
