C# - TextBox.TextChanged Event Not Firing On IE7?

Sep 23, 2010

In my web form I have a Textbox control. The TextChanged event of the Textbox is not triggering.
AutoPostBack is set to true What could be the reason for this?Here is the code:

protected void Textr_TextChanged(object sender, System.EventArgs e)
<asp:TextBox ID="Textr" TabIndex="10" Style="z-index: 117; left: 500px;
position: absolute; top: 158px" runat="server" Height="22px" Width="180px" MaxLength="50"
AutoPostBack="True" CausesValidation="true" OnTextChanged="Textr_TextChanged"

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:


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.

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].....

Update Panel - Textbox TextChanged Event Is Interfering With The DropDown SelectedIndexChanged Event?

Oct 20, 2010

Basics: I have a text box (txtDepositAmount) that people can enter a deposit amount into and a drop down (ddlSelectedTerm) that sets the terms. Through these two values I calculate the APY (lblCurrentApy).

Rules: If only one of the values is selected I still want to do an update on the current APY label and clear it. If either value changes I want to update the current APY and recalculate.

The problem: As soon as I click away from the textbox and onto the drop down to select my term the drop down flashes and closes because the textbox TextChanged event was just fired.

I have to click on the drop down a second time to be able to select anything!

Do I need to change what event I'm looking at or do I need to move some of the controls outside of the UpdatePanel? Can this only happen if some of the business rules change? Should I just give up and go to javascript?

Forms Data Controls :: DataGrid - Setting Focus After A TextBox TextChanged() Event?

Oct 27, 2010

Asp.NET v2.0

Data grid with mulitple texboxes per row.

Each textbox has a TextChange() event wired up for data validation.

These events fire just fine, the data validation works just fine.

My issue is this: User enters text into TextBox1 one then tabs into TextBox2. The cursor appears for a split second inside of TextBox2 then disappears as focus is being set somewhere else on the page. I'm not sure how that change of focus is happening.

In this scenario, after tabbing out of TextBox1, how can I maintain focus on TextBox2 (and then subsequently TextBox3, TextBox4,etc..)
