C# - Setting LinkButton's OnClick Event To Method In Codebehind

Oct 28, 2010

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)

C# - Stop Setting Onclick Event For LinkButton If No OnClick Event Was Explicitly Defined?

Feb 25, 2010

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)

Table Row Onclick Event That Runs Codebehind?

Mar 24, 2011

I've inherited an ASP.NET project that has poorly designed HTML; in one section, the tags are wrapped with an tag to allow for "click the row to view the information" functionality. The code is:

<asp:LinkButton ID="ViewArticle" runat="server" CommandName="Navigate" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "id") %>' >
<tr runat="server" class="list_item">
<td>some data</td>
<td>some data</td>
<td>some data</td>.........

How do I go about tying a JavaScript "onclick" event to the codebehind?

C# - Button Onclick Event (in Codebehind) Doesn't Get Triggered In MVC 2

May 4, 2010

I had an MVC 1.0 web application that was in VS 2008; I just upgraded the project to VS 2010 which automatically upgraded MVC to 2.0. I have a bunch of viewpages have codebehind files that were manually added. The project worked fine before the upgrade, but now the onclick even't don't get triggered. I.e. I have an asp:button with an onclick event that points to a method in the codebehind. When you click the button, the onclick event doesn't get triggered. In fact, when you look at the Page variable, IsPostBack is false.

This is really bizarre and I'm wondering if anyone know what happened and how to fix it. I'm thinking it has something to do with the changes in MVC 2.0; but I'm not sure. (deleting the codebehinds and moving that to the controller is not really an option since there is so many pages, moving back to vs 2008 is a last resort as I want to make use of some of the VS 2010 features like performance testing.)

How To Disable LinkButton When OnClick Event Fires

Feb 11, 2010

<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).

AJAX :: Accordion With LinkButton OnClick Event Not Firing?

Apr 6, 2010

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.

Why Won't LinkButton Inside A GridView Raise Its OnClick Event

I have a LinkButton inside a GridView (via an TemplateField). No matter what I try, the LinkButton will not invoke its event handler.

Web Forms :: OnClick Event Is Not Firing For LinkButton And User Control Is Disappearing

Dec 30, 2010

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.

Setting Click Event For LinkButton?

Feb 22, 2011

I have a LinkButton within a Datagrid. I am having trouble setting a Click event for it. I will add the OnClick="Remove_Click" attribute in the HTML. But when I go to write the actual event, VB isn't finding the LinkButton. Therefore nothing happens.

Here is the code for it.

<asp:DataGrid ID="StandardsDataGrid" runat="server" ShowHeader="false"
ShowFooter="false"
AutoGenerateColumns="false" CellPadding="2" CellSpacing="0"
ItemStyle-VerticalAlign="middle"
DataKeyField="Id" Width="100%" BorderColor="#000">
<Columns>
<asp:TemplateColumn>
<ItemTemplate>

LinkButton's OnClick Does Not Fire In IE8 / Why Can't IE8 Accept Anything Within LinkButton

Oct 20, 2010

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?

AJAX :: ModalPopup / UpdatePanel From Codebehind, Inconsistent Behavior OnClick?

Aug 4, 2010

I have a simple form with a list of linkbuttons, each fires the same onclick event which sets an indicator image. I have a dummy button with style="display:none" which I have set as the TargetControlID of the modal.

onClick event from the imagebutton, the modal is shown via modal.Show(). The cancel button inside the modalpopup fires an event which turns off the indicator image and hides the modal via modal.Hide().

The events fire perfectly, it's very simple! Although after doing some testing I noticed the modalpopup is not presented after the 6-10th cycle of clicking the open event, then clicking cancel. The grey background appears but it is behind the main panel and the modal is either presented behind this or is just simply not displaying.

I spent hours researching various methods, implemented the CancelControlID to see if it was somehow tied to my call of modal.Hide() that fails.This occurs with an updatepanel only. The behaviour is much cleaner this way, so I would hope to be able to implement this. I have basically eliminated everything but these two events!

Web Forms :: LinkButton Inside UpdatePanel Not Executing OnClick Javascript?

Oct 12, 2010

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.

Forms Data Controls :: LinkButton OnClick Inside ItemTemplate Of A DataList Not Firing

Apr 14, 2010

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:

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:

Setting Image Width / Height In Codebehind?

Jul 27, 2010

I am trying to set the width and height of images in a datalist in the codebehind.

The plan is to do something more complex than this based on the width/height, so setting width and height in the aspx file to 50% is not an option.

For some reason I always get 0 for width and height. Image1.ImageUrl is what i would expect though. Image is the System.Web.UI.Webcontrols.Image, not a System.Drawing.Image.
