JQuery :: Html() Method Returns Null After Postback?
Mar 31, 2011
I have a simple page containing a GridView control that generates thead and tbody tags after rendering. In my jQuery script, I have a line that reads this way:
$('#GridView1
thead').eq(0).html()
When the page loads for the first time, this script returns an objects and works well. But when I click a button and cause a postback, it returns null. By the way, the button changes the number of the rows returned from the data source (based on the value of a textbox) and updates the grid.

If I use $get, it does work as the expected functionality for $get. It is only $find that does not work.
Can anyone explain the problem?

I have detailsview control with bound fields...some usingĀ Templatefields. I am trying to access values in those fields but i get nulls....i really dont know why..I am proving all my code....
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Projects.aspx.vb" Inherits="Projects" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">

I guess something might be getting messy with the mode changing event... a postback? But if i remove the databinding code, i get an error! why find control returns null??

I have a webpage with a select object and a GridView object. For testing my problem i've created asp button and html button.On pageLoad the GV is empty and select is being filled with names. (GV is not appearing)After choosing a name from the select options, the user should click a button and then the GV need to be filled with relevant info.I am having 2 "related" problems:
1. When clicking on the asp button and getting into the click function on the aspx.cs file, i can't find the select object and retrieve the selected option. How can i get this?
2. When clicking on the html button and getting into the button_click function on the aspx file (javascript), i can't find the GV object (getElementByID("GridView1") returns null). I guess that it's because the GV is not loaded initialy since it's empty.I've tried also using callback methods, but the although it seems like i am reaching the GV and performing DataBind(), the GV table won't show on the page.

i've a contact form that's plain html and an asp.net button to post everything to server side (and eventually validate).
the problem is that if server-side validation fails, input-values are not manteined.
what's the best client side to mantein fields value?
this is my actual jquery code, i use css selectors:
<script>
$("form").submit(function() {
var asapReqStr = "???";
var asapTmp = $(".asapRequired").val();

I have a very strange issue where SelectionList always returns NULL when i try check its Selected Item/Value. I Googled a bit and I found out that when i click the submit button, the page is being refreshed and the SelectionList is being data bound again so it will revert back to its original behavior.
Then i tried enclosing the binding code in the Page_Load event in a !IsPostBack but still when i try to access the Selected property it is null and an exception is thrown.
My code goes something like this... (the braces are not matched properly)
static SelectionList[] Symptoms;
static string UserID = "";
cmbSymptoms1,cmbSymptoms2,cmbSymptoms3 and cmbSymptoms4 are SelectionLists. I took them in to an array of SelectionList and then set the properties.
I had to make them static or else when i click the button to update, they will not retain their values.
protected void Page_Load(object sender, EventArgs e)
{
if (this.IsPostBack == false)
{
//System.Diagnostics.Debug.WriteLine("Not IsPostBack");
if (Request.QueryString["id"] != null && Request.QueryString.ToString() != "")
{
//System.Diagnostics.Debug.WriteLine("id query string is not null :- " + Request.QueryString["id"]);
myclass = new Class1();...........

I am working on a mvc project, and having problem with json. i have created a demo project with list of colors
public JsonResult GetResult()
{
List<string> strList = new List<string>();
strList.Add("white");
strList.Add("blue");
strList.Add("black");
strList.Add("red");
strList.Add("orange");
strList.Add("green");
return this.Json(strList);
}
i am able to get these on my page, but when i try to delete one color, that is when i send the following using jquery
function deleteItem(item) {
$.ajax({
type: "POST",
url: "/Home/Delete/white",
data: "{}",
contentType: "application/json; charset=utf-8",
success: ajaxCallSucceed,
dataType: "json",
failure: ajaxCallFailed
});
}

I have a class library which has my LINQ doc in it. I added a stored procedure and I get the following in my .dbml.layout :
[Code]....
I include a reference to the dll of the class library to my web project and I get an error about value being returned as int where I am trying to put contents into a datalist or similar.
Code in class that calls this SP :
[Code]....
So I switched code to the following in my dbml.layout document :
[Function(Name="dbo.sp_newsSearch")]public IEnumerable<news_search_result> sp_newsSearch([Parameter(DbType="VarChar(200)")] string searchVal){IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), searchVal);return ((IEnumerable<news_search_result>)(result.ReturnValue));}
And included the following in an external file news_search_result.cs
[Code]....
But now I just get nothing returned. Is this wrong way of calling a SP via LINQ? or have I just put the wrong return type on my LINQ class?

I have a DataTable for which a PrimaryKey constraint has been set to be a combination of an integer column and a datetime column. When I try to 'Find' a row by saying,
dtFunds.Rows.Find(iContainerIndex)
I get a null value. iContainerIndex has been defined as an object array of size 2 with the integer ID and date values in it.
When I set a breakpoint in my code, I see that the very same values are present in the datatable.
If I try to execute, DataTable.Select() method with the integer column filter, I get a result - but returns no result when called with the date column filter.
What am I doing wrong here? The very same DateTime value is present in the datatable.

I want to use multiple targets with my ModalPopUp extender. One of my buttons is set as target in the ModalPopup and the other one will use server-side code to show the ModalPopup.
This is my ModalPopup so far:
<msAjax:ModalPopupExtender ID="modalInform" runat="server"
BehaviorID="modalInform"
TargetControlID="btnSearchUsers" [code].....
Then I found this little tutorial on the ASP.NET AJAX site.But when I use $find("modalInform") in the pageLoad Javascript function (as defined in the tutorial at the bottom), I'm always getting a $find("modalInform") is null error.
This code is included in a usercontrol, the usercontrol is used in a ASPX page and this ASPX-page uses a MasterPage.
I've noticed that if I'm using
<%= modalInform.ClientID %>
I'm getting a different value then defined in my HTML-source (propably because of the MasterPage?).

I am following Chris Pietschmann's solution for theming in ASP.NET MVC.
One thing I have noticed is that the view name is not being retrieved from the ViewLocationCache on subsequent requests. I am using ASP.NET MVC 2.0 RC
When the following code is executed:
this.ViewLocationCache.InsertViewLocation(controllerContext.HttpContext, cacheKey, virtualPath);
and I hover over this.ViewLocationCache it just returns {System.Web.Mvc.NullViewLocationCache} - suggesting nothing was added?

I've been working for a long time with GridViews and DetailsViews, but yesterday I've come across a new scenario, which I quite do not understand.
I have a GridView with ImageButton (CommandName="Insert") which will change the mode of the DetailsView to Insert. Afterwards I'll look for a DropDownList inside that DetailsView and add some items dynamically. Works fine, but one first the first time I press that ImageButton. If I click on "Cancel" in the DetailsView and press the ImageButton again, the .FindControl() Method returns null.
I've created this sample: (To make it run in your Visual Studio, just bind a DataSource to the DetailsView, otherwise it will not be rendered)
Markup:
<asp:GridView ID="gvCategory" runat="server" OnRowCommand="gvCategory_RowCommand">
<Columns>
</Columns>
<EmptyDataTemplate>
[Code]....
I have also tried using a ItemTemplate, and not a InsertItemTemplate, but this results in the same. After using the ChangeMode-Method the DetailsView.CurrentMode == InsertMode. The only thing I can think of is, that the markup is already generated for the ItemTemplate and changing the Mode to InsertMode can't affect the rendered markup, or something like this.

I have a file upload page with an AsyncFileUpload control. When the user browses to the file the upload control pulls the file into memory. I then have an Upload button which fires the following code to save the file to a database.
I am finding that if files are over about 500KB then the FileBytes property of the control simply returns null. This happens on my server but when running the app locally it runs through fine.
I'm not handling the OnUploadCompleted event as I need to user to complete further information before committing the file to database.
I have this in my web.config: httpRuntime maxRequestLength="10000"/>
private void UploadDocument(int mietID)
{
if (Page.IsValid)
{
if (mietID > 0)

I am facing an amazing problem in ASP.NET. I have a website with many sub directories. The sub directories have aspx and aspx.cs files but do not contain web.config files. I am using the web.config file of the parent directory for storing config items for the respective code files in sub directories. But when i m trying to read the web.config using ConfigurationManager.AppSettings[] with absolutely the correct keys, there's no value being returned. Most amazing fact is, this same code works fine in dev enviroment but not in staging.
