TextBox And Calendar Extender When Using AutoPostBack=true Never Fires?
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 theontextchanged="TextBox2_TextChanged" never fires.

Selected Event Not Raised For ObjectDatasource When Enable-caching Is True?
I've a Gridview control using an ODS(ObjectDataSource) to fetch data. For the best performance and efficiency, I've turned-off the view state of Gridview (i.e. EnableViewstate = "false".And I've also enabled caching in the associated Objectdatasource. This eliminates as much as 50-60% performance optimization because it eliminates the DB round-trip .. courtesy ODS Caching.So, after this I got stuck into the famous "ODS sorting" issue but I managed to invent a tricky solution for it and its working fine

Forms Data Controls :: FormView, AllowPaging=true, And AutoPostBack=true?
It took me a little while tofigure this out, but the AllowPaging="true"onthe FormView seems to be the culprit. I don't have much experiencepaging from a FormView, but for thisrequirementthe customers wants this kind of UI.I have a FormViewwith 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.

How To Prevent AutoPostBack When DropDownlist Is Selected Using JQuery
I want to show a confirm dialog when the user selects an item in a DropDownList. If the user presses "Cancel", I want to stop the postback. Here is the function I add to the onchange event:

function imitateConfirmUnload(event) {
if (window.onbeforeunload = null)
return true;

return confirm("Are you sure you want to navigate away from this page?

You have unsaved changes

Press OK to continue or Cancel to stay on the current page.");
}

And this is the relevant bit of code in my startup script to add the handler to the event:

[code]...

The problem is that the postback occurs even if the user selects "Cancel". If I move the handler on to the click event, it works. But it feels clunky to me.

Edit

Correction: it doesn't work onclick, because the dialog prevents selection, so when the user selects OK, no change has taken place, and no postback when you want it!

Edit 2

The DropDownList is inside an UpdatePanel so that may affect behavior.

Get Radiobuttonlist Selected Value In Code Behind When Using JQuery Buttonset?
I am using the jQueryUI buttonset on an ASP.NET radiobuttonlist. I need to get the selected value in server-side code when the page posts back. If I don't apply the jQuery buttonset, this is of course easy enough - just grab "SelectedValue". However, when I do apply jQuery buttonset, the selected value does not appear to be available on postback any longer. Is there any way around this, or do I need to get the selected value on clientside, and then pass it back myself?

<asp:RadioButtonList ID="RadioButtonList0" CssClass="ratingButtons" runat="server">
<asp:ListItem Text="Option1" Value="1"/>
<asp:ListItem Text="Option2" Value="2" />
<asp:ListItem Text="Option" Value="3" />
<asp:ListItem Text="Option4" Value="4" />
</asp:RadioButtonList>
$(function () {
$(".ratingButtons").buttonset();
$(".ratingButtons").click(function () { return false; });
});

AJAX :: Slider And Autopostback=true ?
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.

ANy ideas why this might be? I'm scratching my head.

Web Forms :: Error On Invalid Value In Dropdown With Autopostback True
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 withoutany Custom Error Pages Enabled in web.config file i.e Custom Error Pages are off in web.config file.

JQuery :: How To Change Font Of Selected Charcters In Textbox
Not sure if this can be done. The requirement is to change the font for part of the text in a textbox when a semi-colon (keyCode 186) is typed. This is an ASP.NET 3.5 app.Our corporate environment only uses IE so there are no cross-browser compatability issues. I have written this much so far in jQuery:

[Code]....

This is pretty close. As soon as the first semi-colon is typed, the font of the entire textboxchanges to italics. As soon as the second semi-colon is typed, the font changes back. The requirement is that the font be normal until the first semi-colon is typed and then everything between the first and second semi-colon must bein italics. After the second semi-colon,the remaining charactersmust revert back to normal. This is an example of the text correctly formatted:This is the start; of the string and this is; the end of the string.

Is it possible to change thefont style of only the middle part of the text string? If so, it probably involves creating a range that starts withis the whatevercharacter position of the first semi-colon + 1 and ending at the second semi-colon, right? I just can't seem to wrap my head around this one.

Disable RadioButtonList From Code-behind And Enable It Using Javascript?
I have a scenario where a RadioButtonList needs to be in disabled mode by default and then on some event on client side, say, when a checkbox is checked, it needs to be enabled.

But once I disable it from code-behind, the javascript part of enabling it doesn't work.

Web Forms :: Use RadioButtonList To Enable Dropdown List?
I am trying tohave a radiobuttonlist control enable and disablecertaindrop down boxes depending on theitem selected. The problem I am having is that the radiobuttonlist is alsoaserver/ASP controlthat is bound to a database field. Thus I cannot mix server and client-side code. (Head-slapping compile errors ensue).

From what I can tell I have 2 options:

1. Make the button list control a client side control and use javascript to enable and disable the appropriate dropdown boxes. 2. Use code behind to set the Enabled attributes of the dropdown box.

The problem with 1 ishow to get the value of the radiobuttonlistinto the SQLDatasource. Would it make sense to put a line in the javascript to set the value of the radiobuttonlist to text box that is set as Visible="false" and is bound to the SQLDatasource field? The problem with 2 is that it really doesn't make sense do a postback roundtrip for a purely client action.

AJAX Combobox Adding New Items Without Autopostback="true"
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.

C# - AutoPostBack="true" Doesn't Work For DropDownList With DataSource?

<head id="Head1" runat="server">

[code]....

When I change the value in dropdownList (in browser), it does PostBack, but it selects the first item of list after PostBack - it doesn't save my value.

GetAllDepartments(isDeleted) is a stored procedure, it returns a List of objects with two properties - FieldKey and Name.

Jquery - Delay A AutoPostBack So JavaScript Fires First?
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

Web Forms :: Textbox Autopostback On 5th Character?
Is there a way to have a textbox autopostback when the 5th character is entered into the textbox?

I have a zipcode textbox that I would like to fire an autopostback as soon as the 5th character is entered. Currently I have it so it will fire when tabbed out of or when the next textbox is clicked in but it would save one step for the customer if it fires on the fifth character.

But when i'm trying to find a selected value at the Button_Click() i'm always getting the default value.
