Web Forms :: Button Click Event Not Getting Called Due To Tag?

Feb 23, 2010

In my web form, i am having button named "btnSave" and there are some textbox controls (to name few, Emp Number, Full Name, etc). I've added RegexValidator to the textbox controls as below:

<asp:RegularExpressionValidator
ID="employeeNumberValidator"
ValidationExpression="^[0-9]+$"
ControlToValidate="txtEmpNumber"
ErrorMessage="Only integers are allowed"
runat="server">
</asp:RegularExpressionValidator>

This RegexValidator will check for emp number textbox contains only integers and if not, it will display message "Only integers are allowed". Now, in my btnSave_Click(...) event, i am first validating whether the textbox contains data and if not, then i am highlighting the textbox in red. When txtEmpNumber contains non-integers data and if i click the Save button, the code in inside btnSave_Click(...) event is not getting called. But when i provide employee number in expected format and then click Save button, then the code inside button click event is getting called without any issues.

I am not sure why my btnSave_Click(...) is not functioning when Employee Number has data in incorrect format.

Web Forms :: Button Click Event Is Called Before Page Load?

Oct 8, 2010

I just discover why some validation is working bad on some of my forms: the button click event is being called before page load.

What I need for good is (I consider this is a normal cycle of events):

The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results
But this is what I get (BAD):

The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesnīt loads again and I cant see the results, so my client cant know what happened on the server side

This is how I tried to implement this:

Web Forms :: Button Event Be Called From Another Button Event?

Sep 17, 2010

I have a search page. Based on the user that is logged in, a link will display if they have saved any previous search criteria. If you have any, the link will open a modalpopup with a list of all your saved searches. I have it setup so when you select the search you want to perform, it will take those values and populate the search form for you. What i would like to do is if you select something from the list, after the fields are populated(which is already working) i would like that searches button event to be executed so the search values are passed in and the results are shown instead of having them press the search button again.

I tried adding this to my select event but thats not correct i know.. so is it possible to execute another buttons event?

Button Click Handler Not Being Called Unless Form Action Is Specified?

Mar 9, 2011

I have a simple ASP.NET web application for data collecting (a webform with two text fields and a Telerik editor, a button for submit with server side OnClick event listener attached).The event listener saves data on DB and then redirects to another page.Under development web server the application works fine.When published under IIS7 the event listener doesn't fire. The only way i found to make it work is to specify the action on the form tag:

<form id="form1" action="default.aspx" runat="server">

This is the first time this happens to me, i never run into this problem before with other applications (even more complex!).

Nov 17, 2010

i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).

Web Forms :: Text Change Event Eats Up Button Click Event?

Feb 18, 2011

I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.

Web Forms :: Working With Events / When A Button Id Pressed Only 'Click' Event To Be Fired And Not The ComboBox's 'TextChanged' Event?

Jul 13, 2010

I have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.

I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.

First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.

When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.

I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.

C# - Button Event Handlers Do Not Fire On The First Click But On The Second Click After A PostBack

May 4, 2010

Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.

Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.

I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.

Example of Button Definition (within GetAdministrationInterface)
