<asp:LinkButton ID="LinkButtonNewServicesCategory" runat="server"
OnClientClick="this.disabled=true;return false;"
style="float:left;margin-right:5px;" CausesValidation="False">new services category</asp:LinkButton>
The intent is that when the LinkButton is clicked, it disables itself and returns false to prevent the postback (this control is used as a trigger for an animation).
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 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 RepliesWhat I'm trying to accomplish is to set my dynamically created linkbutton with a onClick command so when click it will run a method in the code behind. This is my code:
protected void Page_Init(object sender, EventArgs e)
LoadLeftSide();
private void LoadLeftSide()
{string filepath = Server.MapPath("DataSource.xml");
List<Post> list = PostHelper.GetAllPosts(filepath);
[code]...
I'm trying to prevent the user of double clicking on a submit button.I have been looking arround for the solution but still can't get it to work.
[Code]....
Now when the user clicks on the button it is diabled and the page,load event is fired. But it does not fire the buttons click event.
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 have a LinkButton inside a GridView (via an TemplateField). No matter what I try, the LinkButton will not invoke its event handler. I have tried both traditional event handler ("OnClick")A OnRowCommand event handler at the GridView level.In both cases, I've debugged and it doesn't even catch the event handler.
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton Text="Cancel" ID="DeleteButton" CausesValidation="false" OnClick="CancelThis" runat="server" />
[code]...
I'm constructing a LinkButton from my codebehind, and I need to assign the onclick to a method, and pass a parameter with it too. I have this so far:
LinkButton lnkdel = new LinkButton();
lnkdel.Text = "Delete";
protected void delline(string id)
I have a ASP.NET Website, where, in a GridView item template, automatically populated by a LinqDataSource, there is a LinkButton defined as follows:
<asp:LinkButton ID="RemoveLinkButton" runat="server" CommandName="Remove"
CommandArgument='<%# DataBinder.GetPropertyValue(GetDataItem(), "Id")%>'
OnCommand="removeVeto_OnClick"
OnClientClick='return confirm("Are you sure?");'
Text="Remove Entry" /
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.

View 6 RepliesThe following works just fine in Chrome.
<asp:LinkButton runat="server" ID="lbEdit" OnClick="lbEdit_Click">
<button type="button" class="edit">
Edit
</button>
</asp:LinkButton>
And here is the CSS for button and its subclass.
[code]...
As you can see, nothing special; just colors and beautiful things.
I click on the blue Edit button and it fires the OnClick postback just fine.... in Chrome! But if I do the same in IE8, it just does nothing; doesn't even detect a click.
I removed the tag and kept just the word "Edit", and it works just fine in IE8 as a simple underlined link; the postback fires.
So, Why can't IE8 accept anything within LinkButton?
I am trying to create a Linkbutton inside a calendar. Everything works except for the onClick.
Is there a way to make this work?

I have an Asp.net web page that has 2 buttons with onclick events. The problem is, when a text field has the cursor and the enter key is hit the first button is triggered and not the seconded one (the one I want). I tried setting the tab index values,
View 2 Repliesi have searched this forum about this pbm. But People posted about Dynamic Image Button .. In my case, this is a static design only. I have a login page with image button as the Login button. I set Panel's Default button to that image button. onclick event Sometime fires, sometime not firing when pressing enter on the password field..If this happens once, then even if i click on the Image button also, the event is not firing.. but the form is post acking....Strange! i have removed panel's default button and wrote this line instead on page_load..

Still, the same pbm persists. Even i click on the imagebutton without pressing enter key also, the same pbm comes sometimes...I couldnt trace why.

why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?
View 3 RepliesI've been looking at google for the past few hours, trying to find an issue to a apparently simple problem. I have a UserControl named RolloverLink that basically contains a asp:LinkButton and a <img /> . I tried setting the OnClick handler like this:
[code]....
I put a breakpoint in the propagate method, but it doesnt stop there. The page does post back (it flashes), but the event doesn't get called.
Here's how my code behind looks like:

I want to restrict the user if they select the language which is already selected by displaying alert msg using JQuery.
Is there any event which fires before the change event.
I feel like a neewbie for this question but I can not make my linkbutton to trigger when created from code behind.What am I missing here?
this is what I got.

So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.
[Code]....
As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window using javascript (Code Behind of the MasterPage):
[Code]....
I build the path using the toolTip of the component that has been clicked,which has the name of the file that should load in the
new window.
When I run the application, and click the ImageButton, the new window opens and the file loads correctly. However, when I click the LinkButton, nothing happens (it should do exactly the same as the ImageButton).
If I set a breakpoint, and debug, when I click the LinkButton, it goes to the LnkRelease1 event (as it should), everything looks fine, but it doesnt open the new window, It doesn't execute the javascript window.open.
I have:<asp:TextBox ID="Profile_EMail" runat="server" CssClass="form" />
and
<asp:RegularExpressionValidator ID="Validator_Profile_EMail"

meta:resourcekey="Validator_Profile_EMail"
ValidationExpression="w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*">
on my ASP.NET form.
When user uses browser embedded autocomplete list and selects any element by pressing "Enter" button, validator fires. Always validation is not passed. Email pattern is proper. When user press "save" button, validation passes correctly.
Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
