Data Controls :: TextBox OnTextChanged Event Not Firing

May 7, 2015

I am using  a calendar extender which is an Ajax control I am selecting a date but the event is not fired.

The reason I am doing this is because I am setting an expiry date based on the date selection.

<asp:TextBox ID="start_date" Width = "165px" Height = "24px" runat="server" OnTextChanged="start_date_click"
></asp:TextBox>
<asp:TextBoxWatermarkExtender ID="TextBoxWatermarkExtender1" Enabled="true" TargetControlID ="start_date" WatermarkText="Start date" runat="server">
</asp:TextBoxWatermarkExtender> <asp:CalendarExtender ID="CalendarExtender1" Enabled="true" runat="server" TargetControlID ="start_date" >
</asp:CalendarExtender>

The code behind

protected void start_date_click(object sender, EventArgs e){
DateTime begindate = DateTime.Parse(start_date.Text);
exirydate.Value = Convert.ToString(begindate.AddDays(days));
}

Is my codebehind code correct. Am i not doing in a right way.

Web Forms :: OnTextChanged Event Not Firing For Textbox?

Apr 3, 2010

On my page, the user is basically registering for a site and I am trying to do a username availability check, without doing the javascript myself(not very good with it yet). The code that is shown below shows the contents for 1 out of 5 textboxes on the page. They all are in the same validator group that is triggered by a button. I have tested the availability query check itself and it works, but only once the submit button is clicked. Nothign is happening when I tab away from the textbox after enetering text.And this page is actually 3 tabs (not sure if there is some sort of a bug that involves tab containers possibly).

I here's the client-sdie code for the page (at least what pertains to this):

And here is the server-side:

Textbox OnTextChanged And Button Click Event Not Firing?

May 20, 2010

I have textboxes being generated by a repeater that use OnTextChanged with autopostback enabled so that I can know when when the values change. This all works perfect.The problem starts when I try to click on any buttons on the page. The loss of focus triggers the event for the OnTextChanged; however, the event for my buttons never get fired. I checked this in the debugger and while debugging if I put a break-point in the page_load it will call both; however, without the break-point it still only calls the OnTextChanged event.I found this post on JavaScript. If my problem is also JavaScript related, why does the clicking of the button fire in debug mode?

AsyncPostBack Firing On Child Textbox Trigger, But TextChanged Event Not Firing?

Jan 22, 2010

I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:

[Code]....

Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.

Web Forms :: Textbox In My App In Which I Have Code Behind In The "onTextChanged" Event That I'd Like To Execute?

Oct 1, 2010

without doing an entire page post back .

I can't use use AJAX not an option for me (corporate thing).

Anyways, I have been struggling with the specifics on implementing ICallbackEventHandler. Or is than another way I can/should do this.The code in the textChanged event pulls a dataset from the DB and does a validation.

Forms Data Controls :: CheckBox Checked Changed Event Is Firing For Every Control Event?

May 8, 2010

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.

Button OnClick Event Not Firing With One Textbox In The Form

Feb 15, 2011

I came across a very strange occurrence with ASP.NET onclick event in IE (other browsers doesn't seem to have this problem). When there is only one textbox field in a form, the onclick event doesn't fire when you enter text and hit Enter/Return. The event does fire when you click on the actual submit button. When there are two or more fields in the form, hitting Enter/Return works just fine.

Javascript - .NET TextBox TextChanged Event Not Firing In Custom EditorPart

Jun 4, 2010

This is a classic sort of question, I suppose, but it seems that most people are interested in having the textbox cause a postback. I'm not. I just want the event to fire when a postback occurs.

I have created a webpart with a custom editorpart. The editorpart renders with a textbox and a button. Clicking the button causes a dialog to open. When the dialog is closed, it sets the value of the textbox via javascript and then does __doPostBack using the ClientID of the editorpart.

The postback happens, but the TextChanged event never fires, and I'm not sure if it's a problem with the way __doPostBack is invoked, or if it's because of the way I'm setting up the event handler, or something else. Here's what I think is the relevant portion of the code from the editorpart:

protected override void CreateChildControls()
{
_txtListUrl = new TextBox();

_txtListUrl.ID = "targetSPList";[code].....

JQuery Datepicker With Validation And OnTextChanged Event?

Problem is when I select a date from the datapicker, OnTextChanged event or validations do not fire as it does when I type values in the textboxes or select it from a calendar control and tab out. CausesValidation attribute supposed to help out but didn't. I can just keep the calendar control.

TextBox OnTextChanged Triggered Twice In Firefox?

Feb 4, 2010

I have a TextBox control with OnTextChanged handler. The event handler is working fine most of the time, but when the user changed the text and press Enter in FF, the OnTextChanged event is called twice. I observed the problem in Firebug that the first request is actually canceled because of the second event.

Test.aspx

<%@ Page Language="C#" AutoEventWireup="True" CodeFile="~/Test.aspx.cs" Inherits="T.Test" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>

[Code]....

Put a break point @ var a, and you'll be able to see that after changing text and press enter in FF (v3.5.7), the OnTextChanged event is invoked twice.

So my question is, what's the best way to properly handle OnTextChanged event so that hitting enter in the textbox doesn't trigger double postback.

Forms Data Controls :: OnClick Event Is Not Firing?

May 6, 2010

The <ItemTemplate> loads properly, and the line:

<asp:LinkButton ID="generalcomments" OnClick="SetPage_N_of_All" runat="server" PostBackUrl=<%#DataBinder.Eval(Container.DataItem, "Filename")%>> <%#DataBinder.Eval(Container.DataItem, "Title")%></asp:LinkButton>

loads the page correctly, BUT it does not fire the onClick event (OnClick="SetPage_N_of_All").

The method SetPage_N_of_All is in the codebehind page and is as follows:

public void SetPage_N_of_All(object sender, EventArgs e)
{
ContentPlaceHolder mpContentPlaceHolder;
TextBox mpTextBox;
mpTextBox = (TextBox)this.Master.FindControl("page_N_of_All.Text");
mpTextBox.Text = RobertBurns.DPM_Current.page_N_of_All;
