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)

VS 2008 - How To Suppress Server Control Event (onclick)

Feb 18, 2012

I have a simple form with a button. The button is server control.

in the OnClientclick event of the button control, I am actually doing some validations. If the validation fails, the onclick event should not be executed. How can I control this?

In the code below, PerformChecks() function gets fired first and alert message pops up fine. But immediately onclick event (which is handled on the server) gets triggered. if the check in PerformChecks fail, how can I suppress onclick event?

Code:
<asp:Button ID="ButtonRun" runat="server" Text="Go"
onclick="ButtonRun_Click" OnClientClick="PerformChecks();" Width="57px" />
function PerformChecks() {
var checkboxCollection = document.getElementById('<%=CheckBoxListInstruments.ClientID %>').getElementsByTagName('input');

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.

I am extending the TextBox class to include CustomValidator along with the TextBox. I have created properties like CSSClass for ErrorMessage, CustomErrormessage for ErrorMessage on failure. But I am not sure how to get server side validation method in the form of tag. Example:

<asp:CustomValidator runat="server" id="custPrimeCheck"
ControlToValidate="txtPrimeNumber"
OnServerValidate="PrimeNumberCheck"
ErrorMessage="Invalid Prime Number" />

PrimeNumberCheck is the method name which is passed as parameter, same way I want to pass method in my custom TextBox for CustomValidator to run on server side.

Web Forms :: Dropdownlist Control SelectedIndexChanged Event?

Jun 22, 2010

I have one dropdownlist control which populates values to other controls. Means upon selecting item in dropdownlist, related data is populated in other controls. I have also assigned dropdownlist's autopostback to TRUE. Everything is working good as far as dropdown has more than one item.

Whenever there is only one item, selectedindexchanged event is not fired (obviously.....) and eventually the data is not populated to other controls.

How could I get rid of this scenario? I mean which event should I use to avoid this?

At this time, I have just added the first item as something like "---Select Item---" , so when end-user has to select different item and thus the selecteditemindexchanged is fired. no biggie... but just wondering if proper solution is available....
