Handle Click Event For LinkButton In User Control From Parent Page?

Jul 20, 2010

I have a LinkButton within a User Control and it has handled with:

Private Sub LoginLinkLinkButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LoginLinkLinkButton.Click
Response.Redirect("/", True)
End Sub

On certain ASPX pages I would like to handle the click from the page's code behind, opposed to within the user control. How do I override the handle within the control from the parent's code behind page?

Update:

Based on the answer, I have the following no added to the User Control:

[code]....

The problem is determining the correct syntax for the if line because the above is invalid.

Web Forms :: Linkbutton In Dynamically Loaded User Control Does Not Handle Command Event

Feb 27, 2011

I have a user control that is dynamically added to a placeholder control inside an update panel in my main page. The user control has a linkbutton where I try to handle its Command event. The first time the link button is clicked after the user control loads, the form posts back but the command event handler does not execute, although the user control is still on the screen. The second and subsequent times the link button is clicked it works perfectly. When the user control first loads and I mouse over the link button, the browser status bar says: javascript: __doPostBack('ctl08$lbTest',''). After the first click, when I mouseover the link button the browser status bar shows javascript:__doPostBack('ctl07$lbTest',''). Why the changed in id, I can't figure but it must be why it is not hitting the event handler the first time it's clicked. Here is the cs code that loads the user control:

AJAX :: Trigger Event Added To Dynamic LinkButton Click Event?

Jun 25, 2010

I have searched around but unable to find a solution that will work. I have a link button that is created dynamically during the page load. It is given an ID (obviously). There is a script manager on the page. I have the controls added to a panel in the updatepanel (updatePanel1). There is a dynamic label that is also created with each link button. I can get a response from the linkbutton click event during a postback on the second time clicking the linkbutton, but I am getting a complete postback instead of the asyncpostback for that control. During the creation of the dynamic linkbuttons, I am also creating a dynamic trigger for each button and adding it to the updatePanel1. The Click event is not firing the method without doing a complete page postback.

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)

LinkButton Click Event Ignored

Apr 28, 2010

I have the following Hyperlink as a button:-

<asp:LinkButton ID="loginButton" runat="server" CssClass="loginButton" Text="LOGIN" OnClientClick="return validateLogin(memNoID,pwID)" AddressOf="loginButton.Click"></asp:LinkButton>

It causes a postback but only executes the onload and prerender sections of code. It totally ignores the following function signature:-

Protected Sub loginButton_Click(ByVal sender As Object, ByVal e As EventArgs)

Some code

MVC :: How To Handle The Onclick Event

Jan 12, 2011

In my View, there is a HTML button; I would like to execute a function from Controller when user clicks on that button. I need to pass a value from HTML textbox as parameters. My function will do some calculating and return the result back to the same View.

Let's make a simple example.

I would like to input "1" in my textbox, press the button, pass "1" to controller, and in the function, I will do something like 1+1. At the end, I will pass the result, which is "2" back to the View.

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>

To Handle A MasterPage Event In A UserControl (C#)?

Aug 19, 2010

I've seen code to handle MasterPage events in the content Page, but if I'm loading a UserControl dynamically into the Page, can I handle the event in the UserControl instead?

Basically I have a button on the MasterPage, when it's clicked I need to make the UserControl do something, such as display text or change a value in a form.Failing that, is it possible to make an event from one dynamically loaded UserControl fire in another on the same page? I could then replace the button in the MasterPage with one in another UserControl

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).
