Web Forms :: Disabled LinkButton Controls With Enabled="false" Still Render Onclick Event Handler
Jun 24, 2010Disabled LinkButton controls with Enabled="false" still render onclick event handler
View 6 RepliesDisabled LinkButton controls with Enabled="false" still render onclick event handler
View 6 RepliesI 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" /
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)
So far, I've seen (and I'm using the following) scripts to show/hide a div or other controls depending on another control in ASP.NET
$('[id$=myRadio_0]').click(function() { $('[id$=myDiv]').show(); });
$('[id$=myRadio_1]').click(function() { $('[id$=myDiv]').hide(); });
and of course, my div in html like
<div id="myDiv" runat="server" visible="false">
and that works fine when the user selects either option of the radiobuttonlist. However, when I assign that radiobuttonlist a value of 1 or yes on my Page_Load on code behind, that isn't (and probably can't be) caught by jQuery, and my div remains invisible even though the control has a value of Yes/1. So, do I need to set the visibility of that div from code behind, or is there a way in jQuery to force a scan of these dependencies after i've set the values for the main controls in code behind?
I would like to call a method and pass a value to it on a link button autogenerated from the database in a templatefield inside a datagrid. I don't know much about delegates
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
..
((LinkButton)e.Row.Cells[(int)eMessage.TitleColumn].FindControl("btnMessageTitle")).Click += new EventHandler(delegate { viewSelectedMessage(this, 35); });
}
void viewSelectedMessage(object sender, int messageID)
{
lblTest.Text = messageID;
}
running the website and viewing the page source, I have realised that there is an OnClick event created for the linkbutton, however, this may be generated anyways. By running my solution using VS debugging, I can see that my method won't fire by clicking any of thos generated linkbuttons.
I have LinkButton as the submit button in the web page. The problem I am facing is it is not calling servr side event handler.
The js function for 'onclientclick' is returning true but the method mapped to 'onclick' is not being called.
I tried putting alert message in onsubmit event also, that is also coming.
How to diagonise the issue? What are the possible reasons for this?
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: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).
What 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);

Trying to get a helloworld web application up running in Visual Web Developer 2010.
Now I created a new project with Home controller and two default views (index and about).
Then in the index view I added a button and a textbox...double clicking the button creates a handler in the view, but it's never called...what am I missing?
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
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)
This is a weird issue. I have a List view with 2 Link buttons. "Edit" and "Delete" Iam able to attach an event handler for the first linkbutton(Update). Code in the event handler executed fine. But If I try to attach a event handler for the second link button(Delete) , I get an error.
My Item Template Looks like this.
[Code]....
First Item works absolutely fine. But If I attach the second handler, I get the following error
Am I missing some thing ? Note - There is no error if I try to attach the 1st event handler to the second link button.[ie EditLinkButtonClicked to DeleteLinkButtonClicked ] Issue occurs only when I try to attach DeleteLinkButtonClicked to DeleteLinkButton
I need to remove certian rows from the Gridview so that certian users can't see certian rows. I have a row databoud event that checks for certian fields in the row and disables the entire row based on the value of those fields. However, it dosen't work well because if my gridview has 20 or 30 rows I have paging so if it disables all but 2 rows the user has to click in the pages of the entire gridview until they reach that row.
View 1 RepliesIn my grid I have three fields: Action date, type name and TypeId. I want to make the Edit linkbutton disabled when the type name is either 'Accepted date' or 'Received Date'. I can do it if there is one condition by the following code, but I can not pass both.
<asp:LinkButton
ID="lbEditAction"
runat="server"
CausesValidation="False"
CommandName="Edit"
CssClass="LinkButton"
Height="19px"
Text="Edit"
Enabled='<%# Not "Accepted Date".Equals(Eval("ActionTypeName")) %>'
Width="39px"></asp:LinkButton>
Is there a way to do this?
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:
[Code]....
<asp:DataList ID="listSearchResults" Border="1" BorderColor="Black"
I have a listview with a linkbutton in it, whenever the user clicks on the link button, I want to retreive the value under:
[Code]....
In my code behind I have
[Code]....
if I change txtstartdate.text = "Testing..", it would work fine with no problem, so everything is working except just finding the value of the username
I am trying to create a Linkbutton inside a calendar. Everything works except for the onClick.
Is there a way to make this work?
[code]....
The 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?

View 5 RepliesI'm trying to make my website to be w3c compliant but I'm having a major drama with asp:RadioButton which have enabled="false" setup from the code behind. As some of you may know already, when enabled="false"; is set it will render the control with the additional <span disabled="disabled"> tag wrapping around the <input /> control.
Well the bad luck is according to w3c validator there is no attribute "disabled" for span. I tried using Attibutes.Add("disabled", "disabled") to disable the radiobuttons but it renders the same way.
I would like to register the website in a competition but it requires to be 100% fully w3c compliant =/
This is the last error that I can't solve... using the native html inputs is an option but is not feasible at this point in time.
I'm using .NET3.5 here.
Is there like a statement somewhere that I can lookup probably to reference this issue, maybe the judges in the competition would understand the situation if there is some kind of explanation.
I am not sure if I am posting this on the appropriate forum but I will give a try.
I have the following code:
