on the code page I have mapped the OnCommand event to the following code
Code:
Protected Sub ImageButton_Command(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.CommandEventArgs)
Try
Dim img As ImageButton = CType(sender, ImageButton)
img.BorderStyle = BorderStyle.Ridge
SortOrder = e.CommandArgument
BindData()
Catch exc As Exception
ProcessModuleLoadException(Me, exc)
End Try
End Sub
My problem is that by clicking on the image button in the gridview header, the OnCommand event is not being fired. I have tried this with both OnClick and OnCommand and neither fires. I can't see what I am doing wrong if anything.
I have an imagebutton with an postbackurl and an onclientclick script. When i added the onclientclick code, if my javascript validation passes (aka returns true), the page just seems to perform a postback (the screen just seems to refresh
I decided to change what JS functions Im calling now since calling Multiple functions definately wasnt helping. Here's my updated code. All Im doing now is validating a single textbox and returning true or false. Even this simple function is causing the postback URL to never get called. Could it have anything to do with the fact that Im trying to call a function to return a true or false?
I have a ImageButton inside a gridview. The gridview is inside update panel. i want to redirect to another page with the Clicking of the ImageButton. But it is not working inside update panel. what should i do?
I 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 have a ImageButton on a master page and a text box. Basically I set the default button to my image button and in the master page I have the following code:-
Code: Protected Sub butSearch_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles butSearch.Click If txtSearch.Text <> "" Then Session("SearchFor") = txtSearch.Text Response.Redirect("~/Search.aspx", True) End If End Sub
When I click on a menu button which has its navigateurl set it works but if I select a different button which loads another content page it does not.
I've got a button inside the gridview that isn't firing the onCommand, ONLY when I uncomment some seemingly unrelated code having to do with session in the page load.
Markup:
[Code]....
Code Behind:
[Code]....
Now here is the odd thing. If I comment out the If Not Session block in the page_load....it works and deleteUser will fire upon a button click. If I leave it uncommented as now.....it won't work.
The weird part is when I step through the code in debug, upon clicking the remove button, it still registers that as being clicked and runs page_load, etc again. But won't run deleteUser.
ive imagebuttons which created in runtime from database and i need to add them onclick or mouseover event but i failed imagebutton.click += new ImageClickEventHandler(imageButton_Click); im adding this when i created imagebuttons, what i need else also i tried javascript but its not firing too;
I have code, where i add ImageButton to table programaticly and I need to assign event handler to this ImageButton. When I write ASP/HTML code, there is attribute OnCommand, but in C#, there is nothing like this. Just CommandName and CommandAttribute.
i have a navigation bar made up of ImageButtons that have their image swapped out on mouse over and back on mouse out. i used this code in the Page_Load handler to do this:
and I want when I click on linkbutton it doesn't open new window...
here when I click on linkbutton it doesn't open new window it is correct but when I click on imagebutton and it opens new window and back to page and click on linkbutton it open linkbutton in new window...
I want when I click on link button it doesn't open new window any way...
I have the following code and no matter what I do onclick event for button is not firing. I tried deleting the button, the pages. Redid the code. Moved the web project to a different computer and nothing. It worked a few hours ago.
I have two problems with a databound AJAX Accordion. The Accordion looks like this:
[Code]....
The code behind has this subroutine:
[Code]....
[Code]....
The first problem I'm having is that this subroutine is not fired (I have a breakpoint in it) when the LinkButton inside the accordion is clicked. The Page_Load event fires and there is no error message, javascript errors, etc, but nothing else happens.
The second problem is that I'm not sure how to go backwards with the databind. I want to be able to make use of the UpdateMethod in the ObjectDataSource because I also have textboxes inside the accordion. I will have a Save subroutine that can be called but I'm not sure what code to put inside it.
I came across a very strange occurrence with ASP.NET onclick event in IE (other browsers doesn't seem to have this problem). When there is only one textbox field in a form, the onclick event doesn't fire when you enter text and hit Enter/Return. The event does fire when you click on the actual submit button. When there are two or more fields in the form, hitting Enter/Return works just fine.
I have a web page which has both asp.net controls as well as AJAX controls.I am facing a weird issue when I introduce some AJAX controls(Modal popup) inside a tabbed panel, the button onClick event stops firing.
I am using the following code to load user control on to ASPX Page, which under a Master Page:
[Code]....
The user control name is passed as a parameter on the URL.
Inside the user, there is a LinkButton. The link button has a simple server side code for OnClick event.
Everything is working fine on the production machine, but, on the Development machine, I can see incorrect behaviour. I have started making some development changes on the Development Machine since several months back, and it will be very difficult to find out what caused the problem.
When I click the LinkButton inside the user control, the user control is removed from the parent page, and the OnClick event of the LinkButton is not firing.
I did debug, and found out that after I click on the LinkButton inside the user control, then the Page Load events for the master page and the ASPX page are working fine, and the IsPostBack is set to true, but the OnClick event of the LinkButton is not firing.
<asp:RadioButton GroupName="grpAssoc" ID="rbtEvery" runat="server" Text="Everyone" onclick="return doChangeAssociationType(0);" AutoPostBack="True" oncheckedchanged="rbtEvery_CheckedChanged" /> but oncheckedchanged="rbtEvery_CheckedChanged" not firing even javascript function returns true
How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)
I created an image button called "pic1" with the OnClick feature. When clicked it runs "btnClicked". In the sub "btnClick", how would I get information? One example is to get the button tooltip. I tried this: request.form.item("pic1.tooltip"). That did not work.
Why isn't the image displayed? The folder images is in the same folder as the .aspx file.Why doesn't it invoke the ImageButton1_Click method when I click on the image? The OnClick should be for the server side.The ImageButton1_Click method takes 2 parameters, but why OnClick does not require 2 parameters?
The 2 parameters are: object sender, ImageClickEventArgs e. What are they and why I pass in a string and a gridview, which I don't think match with the arguments definition, and it still works?
If I use an ImageButton or LinkButton, I just noticed that when clicking either, the Page_Load method executes before the method specified in the OnClick. Can this be avoided so that the method in the OnClick is triggered instead of Page_Load?
