I have the following image button:
<asp:ImageButton ID="submit" EnableViewState="true"
ImageUrl="/images/btn_submit.png" AlternateText="Submit" CssClass="f-right"
runat="server" onclick="submit_Click"></asp:ImageButton>
The event is fired in Firefox but not in IE*.
I can't let my button's OnClientClick fire if the requiredFieldvalidator fails. I created a webform that defines my problem. displayMessageClient() will always run whether
RequiredFieldValidator passes or fails.
I want to run displayMessageClient() only if the RequiredFieldValidator passes

I have embedded an ImageButton inside a GridView.Now I am using a loop to just make the ImageButton visible on the first row and that works great. I use the FindControl to do that and are also putting an Image to that button on the first row.Now is my problem this that this button also needs to have an URL attached to it so when pressing this button it will be possible to open up a Browser with this URL attached to it. I need to use the code that I have in the ImageButton6_Click event as this code is working with IE, Firefox etc... It seems that I should have gotten this correct but dont know why the ImageButton6_Click event isnīt firing when pressing the button. What I get is an Errorpage that says "Invalid postback or callbak argument" etc...

I have a gridview with a ButtonField. When I leave the button type as the default LinkButton, clicking that button fires the RowCommand and everything works as expected. As soon as I change the button type to ImageButton and assign an ImageUrl, clicking that button does not fire the RowCommand.
View 4 RepliesI have to click twice on button control to fire an event.
View 6 RepliesI know this question has been asked before. But for some reason I can't find the exact answer I need for my problem. My problem is as follows:
I am creating a web page (The one posted is just an easy example) that creates multiple ImageButtons on one page via a loop.I have tried many other ways (for example, create instance in form_load and pass to the WriteHtml() method) but I can't figure out a way to complete this. In this example I have 10 buttons that need to be able to be clicked.
The code is as follows:
[Code]....
--AND (CONTAINS(O.OrgName, N'"3 step*"')) ORDER BY O.OrgName ( Contain function fails for a string with single character followed by space)
AND O.OrgName
like
'3 step%'
ORDER
BY O.OrgName(Works
perfectly fine)
Contain function fails for a string like 3 step, @ fire etc which has single characters followed by space.

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 a gridview that has a column with an imagebutton. That image button event calls my update procedure and merely updates that records status and when the gridview rebinds, the image changes and is no longer available.Whats happening is if the page is refreshed, the update occurs again. If i add this around the update code, works great the first time, but then any other updates are ignored.. is there anyway to know wether the page was refreshed vs actual imagebutton postback?
if (!IsPostBack)
{
}
Since the update is just setting a flag for that record, on another page that displays those records for a seperate department. IF by chance the first page is still open and the 2nd department resets the flag, if the first page is refreshed, that flag is reset again. so its creating some inconsistant results..
Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.
Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.
I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.

View 8 RepliesI want to put five buttons: introduction, product, history, feedback, contact. And when I click any one button, that button became dark blue, and others remain, no changes. So I write the following code:
Protected Sub ImageButton1_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton1.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION BLUE.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton2_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton2.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS BLUE.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton3_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton3.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY BLUE.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton4_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton4.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK BLUE.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton5_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton5.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT BLUE.jpg"
End Sub
It is workable, however there is only one problem: when i debug it some times it is ok, but some few times the button suddenly became small.
I have a databound repeater and in this repeater is an imageButton. How do I pass info from the database into the click event? For example, I've got the description, heading and price fields populating labels, but want the id to go into the imagebuttons click event in order to build a querystring.
View 6 RepliesI am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

I'm adding a Button to a TableCell dymanically in code-behind and cant get an event handler to work.
Here's some code...
...
TableCell tc = some TableCell....
Button b = new
Button();
b.Text = "Go";
b.Click += new
EventHandler(OnSequenceChanged);
...
protected void OnSequenceChanged(object Sender,
EventArgs Args)
{
}
I set a break at OnSequenceChanged, but it doesnt hit when I click the button. It posts back - Page-Load gets called - but its event handler doesnt get called.
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"
runat="server"
Width="90%"
AutoPostBack="true"
ontextchanged="txtNewLocation_TextChanged"></asp:TextBox>
In my default Page I register this listener:
[Code]....
and this Event is never fired
[Code]....
Am I doing someting wrong,my event only seem to fire when I click the button,but the text-box does not cause a postback.
