Option - Retain Dropdown Value Page Posting Back To Itself C#?

Jun 15, 2010

I have an aspx page that has...

if (!IsPostBack)
{
PopulateBrand();

in the Page_Load. This PopulateBrand() simply populates my drop down. That works great and on post back it retains the value.

The problem I'm having is that there is also a link on the page that is posting back some parameters to this page. What is happening is that when this is clicked it's falling through this !IsPostBack section and wiping out my drop down values that I had selected and repopulating it.

How can I prevent this and just retain what I selected when this page is posting back to itself when the link is clicked?

Web Forms :: What's Actually Posting Back The PAGE

Jan 31, 2011

when any Button control is clicked generally it Postback the page to itself, and the same page is regenerated.This is the usual defination of postback in context of a Button Control. But my dear friends i am confused that what is the actual mechanism behind this.Okey say for definition the above statement is fine but believe me i not not getting the actual meaning.What is posting back the Page? What is Page in browser's context? There is only html markup, JavaScript and CSS codes in browser's page.These make up the html page. I think there is no any relation of this Browser's page with ASP.NET Page class. What does it mean that browser's content is posted back to the Page itself ?

Web Forms :: Prevent Posting Back To Page Load Method?

May 25, 2010

I have a button on my web form. When it is pressed, the event method for that button is called as it should be. However before the buttons method is called, the page load event is first called. Is there a way to prevent the page load event from being called when the button is pressed? I know about using !Page.IsPostback in the Page load method. However I wish to avoid posting back to the Page Load method altogether when this particular button is pressed.

AJAX :: Page Is Posting Back On Server - Works Ok In Development?

Jan 9, 2011

Got a pretty simple page where i want an update panel to become visible or hidden based on a button click. When i run this page in VS2010 in debug mode it works as i expected it to - page does not post back, the panel just appears or disappears on the page without the whole page refreshing.

I uploaded this to my server, and the page is posting back when you click the button.

Server is win2k8R2 x64 IIs7.5

Do i need to enable anything in the IIS configuration?

Using Javascript Confirm Dialog On A Button Within An UpdatePanel - Posting Back Full Page?

Mar 31, 2011

I basically want to show a dialog box with confirm or cancel options on it.

Confirm should allow the partial postback to take place, cancel should not. I have tried using a trigger and calling __doPostBack() as advised here but it posts back the full page not just the panel.

$('#buttonInUpdatePanel').live('click', function (event) {
event.preventDefault();
var item = this;
var title = 'Confirm';
var msg = 'Please confirm something';
var $dialog = $("<div id='myDialog'></div>")
.html(msg)
.dialog({
modal: true,
buttons: {
"Confirm": function () {
$(this).dialog("close");
__doPostBack('Button1', null); //tried this and .submit() on the button
//return true;
},
"Cancel": function () {
$(this).dialog("close");
//return false;
}
},
title: title
});
});

My UpdatePanel:

<asp:UpdatePanel ID="UpdatePanel2" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:TextBox runat="server" ID="TextBox1" />
<asp:Button
ID="Button1"
Text="Add"
OnClick="AddExtraVehicle_Click"
runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
</Triggers>
</asp:UpdatePanel>

UPDATE:

I have changed the doPostBack to use the button ID now and commented out the return true and false lines. When I click the button it calls the confirmation dialog but when you click on confirm it appears to do nothing. I was expecting a call to the method AddExtraVehicle_Click but the breakpoint didn't trigger.

Web Forms :: Can't Select Dropdown List Option If There Is Only One Option Returned

Jun 29, 2010

I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.

I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)

2 Update Panels Always Posting Back?

Nov 16, 2010

i have the below page and i am racking my brain as to why when i have two update panels do they both get post backs. i can tell cause i have two user controls- one in each panel and they both fire page load events when only the left panel should be posing back and updating itself... or else whats the point of update panels if in reality the entire page is posting back!

<asp:Content ID="StyleContent" ContentPlaceHolderID="Style" runat="server">
<link href="../Styles/ReportWizard.css" rel="stylesheet" type="text/css" />
<div class="clearFix"></div>
<div class="wizardContainer">

AJAX :: Posting Back A Disabled Button?

Aug 26, 2010

I have a control which inherits from LinkButton and I'm trying to make sure that the user cannot cause mayhem by performing multiple postbacks. That seemed an easy enough challenge, so I have this code [snippet] on the client:

[Code]....

The alert is of course only there for debugging. If the DisableOnClick value is false, then I see the "Posting Back" alert and, when I click ok, the postback occurs - all good.

If the DisableOnClick value is true, then the "button" gets disabled and the cursor turns into an hourglass - again good. But the postback doesn't happen - not good. I assume that the ASP client code is trying to preventing the postback when it sees that the link is disabled.

So, how can I either:

Persuade the LinkButton to postback even though it has just been disabled; or[probably better] Get my client code to execute immediately after the postback code rather than before.

Avascript Onclick _dopostback In MVC Not Posting Back?

Jul 23, 2010

I'm using ASP.NET MVC to try to postback after confirmation using javascript, this is the button:

<input type="submit" id ="RemoveStatus" value="Remove Status" name="button" onclick="return CheckRemove();"/>

This is my javascript in my CheckRemove() js function:

var button1 = document.getElementById("RemoveStatus");
if (confirm("Are you sure you want to remove status?") == true)
{
button1.disabled = true;
button1.value = "Removing status...";
__doPostBack('RemoveStatus', '');
return true;
}
else
{
return false;
}

But for some reason I get an object expected error at the __doPostBack bit, I've clearly set the id, button1 gets populated too in debug, i'v tried passing button1.id and button1 too into the __doPostBack call but it wont postback and keeps saying object expected.
