TextBox And Calendar Extender When Using AutoPostBack=true Never Fires?

Jan 30, 2010

I have the following sample code

[Code]....

[Code]....

When I place a value in TextBox1 and then click inside TextBox3 (which is there to have a place to go to get out of TextBox1 and TextBox2) the value from TextBox1 remains and is displayed in the MessageBox.Show correctly.

When I pick a value from the drop down calendar extender in TextBox2 for a brief micro-second the value from the calendar displays in TextBox2 and then the MessageBox.Show displays and the value in TextBox2 returns back to the orginally set value. The MessageBox.Show shows the orginally set value.

For TextBox2 if I set AutoPostBack=false then the TextBox2 works correctly and keeps the date picked from the calendar extender but the ontextchanged="TextBox2_TextChanged" never fires.

Forms Data Controls :: FormView, AllowPaging=true, And AutoPostBack=true?

Feb 24, 2010

It took me a little while to figure this out, but the AllowPaging="true" on the FormView seems to be the culprit. I don't have much experience paging from a FormView, but for this requirement the customers wants this kind of UI.I have a FormView with DefaultMode="Edit", which is bound to an EntityDataSource. One of the entity's properties, "ExternalID", determines whether some of the other properties in the entity are read-only. For example, if IsExternal==null, the FirstName, LastName, and Email fields should be rendered as TextBoxes. If IsExternal!=null, the 3 properties should be rendered in Label controls.

Jquery - Delay A AutoPostBack So JavaScript Fires First?

Mar 2, 2010

I've got an odd situation with a text box and an autocomplete setup on my page. I'm using a JQuery based autocomplete on a text box that has AutoPostBack="True". This works perfect if I use the keyboard to select an autocomplete item, which then fires Jquery to fill in the text box, and then when I tab out of the box the AutoPostBack fires. If, however, I click on an autocomplete item, my text box loses focus first and the AutoPostBack fires before the Jquery has a chance to change the text in my text box. Is there a way to delay either the PostBack or the Jquery so that they don't fight each other? I'm thinking it may have to be the PostBack that gets changed, since the JQuery would lose it's state on the PostBack

DropDownList AutoPostback Fires When Asynchronous Postback Occurrs?

Aug 26, 2010

Well I have a strange problem.I have a page with 2 DropDownLists on it and a custom web-user-control. The custom web user control has an UpdatePanel within it, and an Ajax Timer control within the UpdatePanel to periodically update a listing of stuff.When I "drop-down" one of the DropDownLists and hover over (not click on) an option while the Timer control within the UpdatePanel asynchronously posts back to the server, the DropDownList "autopostbacks" to the server!

I'm trying to figure out why an asynchronous postback would cause the DropDownList to act as if I selected/clicked on an option so that I can find a way around this issue.Now it's really simple to reproduce this problem. Create a Web User control called "TimerUpdatedListing"...this is the ASPX code markup for the web user control:

<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="TimerUpdatedListing.ascx.vb" Inherits="MyNamespace.TimerUpdatedListing" %>
<div style="width: 150px; height: 150px; overflow: auto; border: solid 1px navy;">
<asp:UpdatePanel ID="anUpdatePanel" runat="server">

AJAX :: Slider And Autopostback=true ?

Sep 23, 2010

I have three AJAX sliders and each has a:

<asp:AsyncPostBackTrigger ControlID="Slider1" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="Slider2" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="Slider3" EventName="TextChanged" />

When I do a TextChanged event on slider1 (by dragging the slider, changing the value), the protected void Slider1_TextChanged(object sender, EventArgs e) event FIRES, however, the TWO other sliders, protected void Slider2_TextChange, and protected void
Slider3_TextChange also FIRES. What gives? why do they fire when I am physically only sliding the slider1 across. The two other sliders values did not change on the webform, yet the event fired.

In order for the event to fire for slider1, I had to insert "Autopostback=true" in the <asp:TextBox ID="Slider1" autopostback="true" OnTextChanged="Slider1_TextChanged">. For <asp:TextBox2> and <asp:Textbox3> I did not put the autopostback event for now.

Web Forms :: Error On Invalid Value In Dropdown With Autopostback True

Feb 3, 2011

I am getting the following error as Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. when an invalid value is passed in dropdown with autopostback=true. What should I do. I want the solution with "EventValidation=true" and "ValidateRequest=true" in the Page directives. Also without any Custom Error Pages Enabled in web.config file i.e Custom Error Pages are off in web.config file.

AJAX Combobox Adding New Items Without Autopostback="true"

Jan 25, 2011

Buenos nachos, to be brief, my question is: is it possible to allow users to add new items to a combobox at runtime without having the autopostback property set to true? I understand it needs to postback if a new item is added, but I do not want the box to postback if the user simply selects a different value!

The tag I currently have is below. Without having the autopostback="true", the comboxbox doesn't allow the user to add new items to the box >_<' Any thoughts?

<ajx:ComboBox ID="cbCompany" runat="server" Width="226px" DropDownStyle="DropDown"
OnItemInserted="addCompany" AutoCompleteMode="SuggestAppend">
</ajx:ComboBox>

I know I could add a few more controls and do an easy workaround, just wondering if it is possible to do it this way.
