Page_load Fires Twice For UpdatePanel Refresh Whilst Having A JQuery Bound Change Event On A Dropdown List?
Sep 11, 2010
I've tried to wrap up my problem with a complete example below - the original problem is part of a jQuery plug-in that I'm writing to extend the behaviour of an ASP.NET ajax application I already have.
The aspx page below has one drop down list which is marked for auto post back. I've also bound a change event using jquery (which ultimately I will swap for a .live() event to maintain the binding after the update panel refresh.) The problem is, when the jQuery event is bound I see two ajax begin requests and page_loads fire but only one ddlTest_OnselectedIndexChanged event. One of the page loads is malformed too - the content-length states it's about 300 bytes long whilst the totalBytes is 0 and form data empty. This does not happen if I bind to the click event of a button.
why the erroneous page_load event is firing ?

We are developing our application on a 64 bit server. We are using a dropdownlist to filter and display departments in a htmltable(hide and show rows) on every selectedindexchanged event.
The issue is it is firing properly for the first time, but it is not doing a post back there after. We have even given autopostback=true. We are using AJAX for hiding and showing the rows of the htmltable.

I am using AJAX extension in visual studio 2005. First of all i am created a Web custom control which contains Dropdown list. I have also set AutoPostBack="true" for getting its SelectionEventChange event.
I am added this web control on another page inside a UpdatePanel.(i added dynamically on another page).
MyControl = (MyControl) LoadControl("MyControl.ascx")
My problem is when i select the values from dropdown it refersh my whole update panel.
<Triggers>
<asp:AsyncPostBackTrigger ControlID="DropDownList1" EventName="SelectedIndexChanged" />

Page_load event fires two time in firefox and the same page is working fine in IE. What might be the problem? If it is problem with Autoeventwireup then page_load event must fire two times in IE too. I believe it is not a issue of Autoeventwireup.
how can i find out exactly where the issue is.

I have a dynamically created user control which is accomplished usingLoadControl().
When I debug, the LoadControl call is called once, however the Page_Load inside the user control is called twice. On each occasion, the postback property is false, so it seems somehow the Page_Load event is called outright 2 times and nothing to do with any postback?

Basic concept of AJAX is to cause Partial post back of the Page. If we use AJAX, Page Load occurs, than what is the difference between normal Pages' Page_Load event (without ajax) and Page load event of a Page with ajax.

How to bound countries list using DropDown list in VB ASP.Net?

I have a databound FormView with a dropdown list of categories. All works as expected, but I want to provide the facility for the user to add a new category to the list and I can't find an elegant way to do it. My current approach is to have a simple modal popup (Ajax toolkit) with a FormView (bound to the Categories table). That successfully inserts the new row, but it doesn't show in the dropdown so it can't be selected. I can force a refresh by calling formview.DataBind() in a suitable event handler, but that of course moves the formview off the selected record and loses any changes the user may have made.
Is there a convenient way (perhaps using AJAX, avoiding a postback entirely) to update the Categories table and refresh the dropdown without moving off of the current FormView's record? I feel sure this
must be a frequent and basic requirement, but I've not found any mention of how to implement it.

I've got the an bit of ajax and the succeed runs twice. I've got a global var that I used to keep track.
Code:
var counter = 0
$('#txtLookupText').keyup(function(event) {
$(document).ready(function() {
});
$.ajax({
type: "POST",
url: 'ContactLookup.aspx/LookupContacts',
data: "{'inputStr': '" + $('#txtLookupText').val() + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
AjaxSucceeded(msg);
},
error: AjaxFailed
});
});
function AjaxSucceeded(result) {
if (result.hasOwnProperty("d")) { result = result.d; }
var li = ''
for (i = 0; i < result.length; i++) {
li += result[i].FirstName + ' ' + result[i].LastName + '
}
counter += 1
alert(counter)
}
function AjaxFailed(result) {
alert(result.status + ' ' + result.statusText);
}
I moved the counter to the POST and only got one alert box. In the succeed, I get 2 alert boxes in succession.

I'm trying to use jquery lightbox functionallity when a user clicks on a button in my View, to give a friendly message "Please wait whilst we generate your data etc" whilst the second view that contains a lot of data is being generated. I was hoping to have the friendly message stay on the screen until the second View is ready to be displayed. At the moment the form submit button fires the popup but the button itself is not getting clicked, only the surrounding anchor tag:
<a id="inline" href="#data"> <input type="submit" value="Submit" /></a>

In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
My coding is as follows:
protected void Page_Load(object sender, EventArgs e)
{
try
{
if (Session["sesUserName"] == null)
{
Response.Redirect("sessionExpr.aspx", false);
}
else
{
lblStatus.Visible = false;
pnlEvaluate.Visible = false;
if (!IsPostBack)
{
fnLoadDropDown1();
fnLoadDropdown2();
}
}
}
catch (Exception ex)
{
throw ex;
}
}
public void fnLoadDropDown1()
{
dsLoadDD1 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD1.Tables[0].Rows.Count > 0)
{
ddTestTitle.DataTextField = "vchTestTitle";
ddTestTitle.DataValueField = "intTestID";
ddTestTitle.DataSource = dsLoadDD1.Tables[0];
ddTestTitle.DataBind();
}
}
public void fnLoadDropDown2()
{
dsLoadDD2 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD2.Tables[0].Rows.Count > 0)
{
ddUser.DataTextField = "vchUser";
ddUser.DataValueField = "intUserID";
ddUser.DataSource = dsLoadDD2.Tables[0];
ddUser.DataBind();
}
}
protected void ddTestTitle_SelectedIndexChanged(object sender, EventArgs e) ...................

I have noticed that window.onunload event fires off AFTER page_load event which makes no sense.
This behaviour is creating an issue for me - in my unonload I clear the session, so if the Page_Load first BEFORE onunload, there are errors on the page displayed.
I would expect the javascript onunload to fire BEFORE Page_Load....is that the correct assumption?
TO CLARIFY: Let's assume I am on page test.aspx, then I click on the link that goes to the same page (say I click on a menu), what I observe is that Page_Load fires first, then onunload fires off.
Makes no sense at all.

I have a web page with a nested grid. I bind the nested grid via the outer Gridviews RowDatabound. The problem I'm having is when a user click on a CommandField in the nested child grid the Page_Load event is fireing twice and reloading the grids, making it appear that the nest grid collapsed. I have tried using "If Not Page.IsPostBack" but because the page posts back twice the IsPostBack is false until the second time the Page_Load event fires.
Here is my Page_Load routine
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim test As Boolean = ScriptManager.GetCurrent(Me.Page).IsInAsyncPostBack
If Not Me.Page.IsPostBack Then
If Not ScriptManager.GetCurrent(Me.Page).IsInAsyncPostBack Then

I have a dropdown list within a details view that allows me to set 1 or many categories to a perticular record(in this case a photo). The select command in this case only displays those catetegories that are not already attached to the selected photo.
all works well and as you select a category and add it to the database the category is removed from the dropdown list and is added to a gridview which shows all categories that photo is stored with.
My Problem is that when i delete the category from the gridview the dropdown list does not delete with said deleted item unless i do a "click in URL bar and press enter" to totally refresh the page.....
how to refresh the dropdown list in the details view after the gridview item has been deleted?

You must have noticed one link in yahoo.com, msn.com or other popular websites named "Page Options". When you click this link you get a popup displaying different small several color icons. After clicking one of these icons your page theme changes without entire page refresh. Now you are able to see the same page with different look and feel.
How does it happen and what it takes to do it? Is this possible in ASP.NET? If yes, how to do it?

I have a drop down list that is populated in the page load event from a database table. The drop down has a DataTextField set to a project name and the DataValueField set to the project id (interger). Later I change the dropdowlist selected item with this code in the selectedindexchanged event of a gridview
GridViewRow row = GridView1.SelectedRow;
ddlProjectList.SelectedItem.Text = row.Cells[2].Text;
Does Changing the drop down list with this code cause the DataValueField property to change to the correct Project ID number also? If not is there a better way to do this? actually this code seems to be adding an additional item to the list so that the project i set with this code is listed twice so I don't think my code is correct
