Javascript - $(document).ready(function() Does Not Work Perfectly In Content Pages / Telerik Controls

Jul 22, 2010

The pages on my project are base on master and content pages...

I want to do something with javascript(rather than jquery) in one of content pages after ALL OF MASTER AND CONTENT ELEMENTS ARE LOADED COMPLETELY.(for example set focus on a RadComboBox Control)

For doing that I used the below code :

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<script src="../JQuery/jquery-1.4.1.js" language="javascript" type="text/javascript"></script>
<script type="text/javascript"> [code]...

But alert(combo); always returns null.(the $find code is for telerik controls and the upper codes about telerik controls are completely true)To solve this null problem I test the ways shown below:

1-I Removed all of controls from master and content page except RadComboBox Control and null problem disappeared , so i derived the null peoblem is about all of elements of master and content page have not been loaded when

$find("<%= RadcbPersonelCompleteNameInvwNoskhehEdit.ClientID %>"); is fired.

2-so i used $(document).ready(function() { my codes }); instead of onload = onloadOfDocument;

3-at last i test the below code and it works perfectly :
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<script src="../JQuery/jquery-1.4.1.js" language="javascript" type="text/javascript"></script> [code]...

What function of document should i use for doing some javascript codes after all Of MASTER AND CONTENT ELEMENTS are loaded completely?

How ToI Do Document Ready() Functions For The Child Pages

Jan 26, 2011

I want to use jQuery in my ASP.NET 3.5 website that uses master pages and content pages. How do I do document ready() functions for the child pages for those that will use jQuery ? Where do I put the code?I figured the jQuery declarations should go in the master page, but don't know how to make sure any jQuery calls go into the HEAD of the resolved page.

Forms Data Controls :: Hoe To Update Row Can Work Perfectly

Dec 5, 2010

I've inserted some changes into the page in which the gridview is nested, and I'm not sure what I did, but it managed to somehow disable the "Update" button operation.When I click on "Edit" - It goes into edit mode perefectly. But when I click on "Update" the page refreshes itself without doing anything (it stays in Edit mode).As I mentioned, everything worked great until now, but a small change somewhere probably gets in the way. The changes I was talking about were adding some ajax into the page, but most of it was ultimately left out. (No UpdatePanels what so over... Only a TextEditor, that I had there before).

ASHX Image Handler Lets Document.ready() Fire Twice

Nov 1, 2010

I got a $(document).ready() handler in my aspx page that fires twice. I trapped it to the follwing line of html (this line is part of the itemtemplate of a listview):

<img src='Images.ashx?Url=<%# Eval("Url")%>&Type=3' alt=''></img>

Seems that using the images.ashx is causing my problem, putting a 'normal' url as src gives me no problems.

It must be because the handler is called, but why is loading an image giving a second fire on $(document).ready()

It is only in IE8. Chrome, FF and safari work as expected.

JQuery :: Update Panels - Functionality Disappears Using Document.ready()

Mar 24, 2011

I have a problem with JQuery when using update panels. My page is structured like this:

Text search
Login Update Panel
Login form
End of Login Update Panel

For clarity I have remove all other page objects. As you can see the login form is inside an update panel, the text search is not. Both of these objects rely on jquery to function correctly (assuming javascript is enabled). In order to persist the functionality after postback with the login form, I use the PageLoad() function. This works ok.

I tried the same with the text search but it doesnt work. I presume its because it isn't inside the updated update panel. At the same time the functionality disappears using document.ready() and I can't understand why it works with neither rather than one or the other.

Visual Studio :: How To Work Only On Content Place Holder In VS2010 Without Seeing Master Pages

Jan 25, 2011

I am wondering if it's possible to work on Content Place Holder window without seeing master page template?

The second problem i've noticed is that when i try to add a table (1 row, 3 columns) to my content place holder and then try to adjust the width of those columns the whole layout of my page is getting messed up to the point that i have to use ctrl+x to go back to previous stage. The master page was very complicated but i finally got it to work and i don't understand why while i manipulate contentplaceholder the layout of the master page is being affected. (only when adjusting tables)I am new to Visual Studio and was wondering of any known standars in that matter.

Web Forms :: Javascript In Master Not Appearing In All Content Pages

In my master page, I'm using a javascript dropshadow. Obviously, I want it to appear in all of my content pages, but at the moment it's only showing in my home page. I've not done anything to override my master page (that I know of!), so I'm quite confused. Has this happened to anyone else? What other info do you need?

VS 2008 - JavaScript GetClientRects Does Not Work In Content Page

Apr 20, 2012

I have a aspx page with a table with scrollable rows..I achieved this by having a "header" table, and a "rows" table. The rows table has a div with "over flow:auto" so get the scroll bar. When data is loaded in the rows table, the columns have different sizes, and since the columns are not fixed width, the header columns don't match with rows columns.

using JavaScript, I loop through the first row in the "rows" table, and I call the getClientRects() function to get the cell bounds, calculate the column width and assign that value to the header table columns. This works perfectly when I use a regular aspx page. I decided to switch to a master-content architecture, because I have a tab menu at the top of the page, and I copied and pasted the code into the content page. Everything works fine, but the getClientRects() returns all values as 0 (zeros). So how can I get the getClientRects() to return the propper values ?Here is the relevant code:

ASP Code:

<script language="JavaScript" type="text/javascript">   
function SetTableColWidth() {       
var th = document.getElementById("tbl_SearchResult_Header");       
var tr = document.getElementById("tbl_SearchResult_Rows");        
if (tr != null) {     

[code]....

Web Forms :: Timer Executes Page_Load That Should Execute Javascript Function But Does Not Work?

Feb 10, 2011

I am using a Timer with a 3 minutes interval. I am exeuting the Page_Load event every 3 minutes. I am doing that this way as I have all this code inside an UpdatePanel1 which causes

a partial unnoticed postback to the server. I have a lot of code in the Page_Load event that I haven´t put here.

But what does not work is the code I have in the Page_Load event now.

I am trying to execute the javascript function with this line: body1.Attributes.Add("Onload", "startbk()");

This function should start an imageButton to change image between 2 images. This function do works if I refresh the page so the function itself do works.

But it seems this function does not execute when the Timer executes the Page_Load event, so this is my problem how I can solve this?

Converting Content Pages To Nested Master Content Pages In .net

Jul 28, 2010

I have a main master page, say MasterPageMain, and a couple of folders with couple of pages in each folder which act as a child page to that master page - MasterPageMain.

Now, I have about 10 pages in one of the folder which follows a certain pattern and they could really use a nested pages since any change on some parts needs me to change all the pages which is a pain really.

I already added a Nested master page, say NestedMasterPage - which is a child of MasterPageMain

I tried to change one of the page's <%@ Page directive to NestedMasterPage, immediately, there were a lot of errors. plus I dint know where the NestedMasterPage's children content would go.

What do I need to know in order to do this succesfully?

ps: I dint do this initially because I only had 2 pages, and I dint need this at that time, as the project grew, now i see that I should have changed it much earlier..

Design Pattern(s) For A Webservice Enabled Telerik Treeview For Navigation Of A Document Site?

Oct 11, 2010

I am currently working on a document management system in ASP.NET 3.5 using the Telerik AJAX toolkit. It consists of masterpage with a title banner across the top and a RadTreeview down the left hand side for navigation through the site. The treeview uses a combination of static nodes and dynamic ones. The dynamic nodes are populated via a webservice. When a node is clicked the relevant page is navigated to, reloading the masterpage and displaying the content of the target page.

The problem comes from the fact the treeview's dynamic nodes are populated via a webservice and therefore as the user navigates through the tree to find a document the treeview behaves as you would expect. However, when you get to the bottom of a tree of dynamic nodes the navigation to the page of the navigateurl causes the relevant page to be loaded and then the treeview resets itself to a collapsed state. This means the user could be deep in a nest of documents but when they view one, the tree collapses and they have to start their navigation all over again. This limitation is not going to be acceptable from an ease of use perspective.

According to Telerik, this is the designed behaviour for performance reasons - the node only ever worries about populating the next set of nodes and therefore the treeviews state is not remembered in viewstate.

So, the meat of question is. Is the masterpage/async treeview navigation design pattern a valid one? Are there any other ways to have an ajax treeview on a masterpage, that remembers it's state when another page is navigated to? I have considered a siglepage/updatepanel/partial page rendering model but the opinions I've seen on the net infer that this is bad idea. It confuses users that expect back/forward browser behaviour to navigate through the site but in a single page world they would end up leaving the site.

I also thought that maybe using a single page container and an iframe may work but this seems to be moving away from the "standard" design pattern of using masterpages.
