How To Refer To The PlaceHolder In A Masterpage In Childpage Using JavaScript
Oct 18, 2010
This is my master page code
[Code]....
Now what I want to do is, using JavaScript, hide the "phMenu" contents in the childpage. For this, I have written a function called " showHideMasterPageContent " in the masterpage which I am calling in the child page.
My trouble is that, I get a null reference since obviously, when I looked at the source, I see that only the contents of phMenu are rendered and not the phMenu control itself. Now how to refer to phMenu in JS ?
am using master page in visual studio 2005. I want to fetch the drop down value which is there is the master page in my child page using the code below
This works fine without using a masterpage. What is the masterpage messing up here. Basically creating all dynamic controls. Linkbutton>tablecell>tablerow>table>panel>placeholder. The linkbutton id is not being set when building. The link button id is registered fine when not using the masterpage. Also using ajax.
However, ever since I have introduced the notion of content place holders (from a master page), I am repeated getting the Object Expected error.Now I understand why this is happening, asp.net is amending the control names to take into account the CPH i.e. $('#ctl00_ContentPlaceHolder1_radBuyer').attr('checked', true);
How do I go about reslving this issue, effectively 'renaming' my asp.net controls to take this into account?
I have a nested table structure, a part of which is rendered by a ajax call that returns HTML from the server. The markup looks like this:
<tr> <td><table cellpadding="0" cellspacing="0" border="0"> <%-- Content will be displayed from ajax call 1 --%> <%-- Content will be displayed from ajax call 2 --%> </table> </td> </tr> </table> .. more html
In jquery, I need to insert this html for which i need an element to traverse to so that I can call the html() of that element. Unfortunately, if I use a div, for example:
<table cellpadding="0" cellspacing="0" border="0"> <div id="divAjax1"> <%-- Content will be displayed from ajax call 1 --%> </div> <div id="divAjax2"> <%-- Content will be displayed from ajax call 2 --%> </div> </table>
the classes are setup such that the div or a span causes other issues.
how to maintain state of placeholder. i have a placeholder in which i add many image controls dynamically but when my page get refresh all controls from placeholder gets removed from it. the enableViewstate of placeholder is set to true.
problem, i've been 3 days more to solve this by myself but i got nothing.. really tired here.
Here's the situation :
1. I want to create a table (gridview) dynamically (programatically) 2. After i created that gridview, i have plan to put it into PlaceHolder.
And here's the problem :
- Whenever i create that table based on OnLoad Event the result is good, data is bounded normally, and from the HTML script i can see the table's script from <table> until </table>
But the main thing :
- If i generate that table not using the OnLoad Event, say, using Event from Click Button : the result is, this gridview printed normally, and the data also bounded normally, but i cannot see this table script using HTML... so far what i could see is <div> (as this is a placeholder).
Did i do something wrong here ? i really need this HTML script for generating other code based on this table, some other action i want to generate are saving data as per row, and authenticate it using javascript.
I am using list view to display the the data but i am getting an error like An item placeholder must be specified on ListView 'ListView1'. Specify an item placeholder by setting a control's ID property to "itemPlaceholder". The item placeholder control must also specify runat="server.Even i have specified the itemplaceholder id but no use still same error.
sir i want to add javascripts in my website. i have used master pages and sub pages in my website so i want to apply validations in my website. so tell me where to place javascript code either in master page or sub page?
I am using javascript for customValidator to validate textboxes in ASP.Net. The code works perfectly when I am using a normal page, but as soon as I put that inside a MasterPage, the code doesn't work. Below is the code for my aspx page. If I put this code inside a MasterPage it doesn't work.
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <script type="text/javascript"> function validateOrFields(source, args){ var sUser = document.getElementById('TextBox1'); if (sUser.value == "") { args.IsValid = false; } else { args.IsValid = true; } return; } <div> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:CustomValidator ID="FieldValidator" runat="server" Text="Enter either a user name" ClientValidationFunction="validateOrFields" onservervalidate="FieldValidator_ServerValidate"/> <asp:Button ID="Button1" runat="server" Text="Button" /> </div> </form> </body> </html>
does anyone have any working code that uses javascript to open and close a cpe when the CPE is in a masterpage? It seems like the javascript never is able to find the CPE when it is on a master page. I have an DropDownList on the page and when certain items are selected, i want to collapse or expand when others are selected. It seems to work fine on a regular page, but not when it is a page nested in a master page. It is adding a suffix to the CPE and javascript is unable to find it.
I need my MasterPage to be able to get ControlIDs of Controls on ContentPages, but I cannot use <%= xxx.CLIENTID%> as it would return an error as the control(s) might not be loaded by the contentplaceholder.
Some controls have a so called BehaviourID, which is exactly what I would need as they can be directly accessed with the ID: [Asp.net does always create unique IDs, thus modifies the ID I entered] Unfortunately I need to access
e.g. ASP.NET Control with BehaviouraID="test"
document.getElementById("test")
if I were to use e.g. Label control with ID="asd"
document.getElementById('<%= asd.ClientID%>')
But if the Labelcontrol isn't present on the contentpage, I of course get an error on my masterpage.
I'm using Lightbox but i only want the references to the stylesheet and javascript files to be in the masterpage header on one page on the site (the page that uses lightbox). how do I programmatically add references to the stylesheet and javascript files in the page load?
the stylesheet is the 'css' folder and the three javascript files are a 'js' folder
I am using a Masterpage for my upload_photo.aspx which displays the file upload page using colorBox. However, ever since i added (code below) in the Masterpage colorBox doesn't display:
I am using ASP.NET MVC 2 in Visual Studio 2010. I have a ASP.NET MVC application with a master page that contains 3 content placeholders. When I create a new view from a controller by right-clicking the action method and selection "Add View", I end up with a ASPX page that does contain the 3 content placeholders but in the wrong order. This is by design because in the T4 template used to create views "TitleContent" will be used first followed by the "MainContent" and after that all the other content placeholders are put.
I have a subtitle content placeholder in my master page that I want to put before the "MainContent" placeholder. Is there a way to achieve this with modifying the Create.tt T4 template?
I am trying to put google adsense on my default.aspx that has a masterpage. I am not sure I am doing it correctly. Is there a particular place I should be pasting their java script ?
I have an UpdatePanel on the page which I'd like to trigger using javascript.First of all my code perfectly works if it's in a website not being inheriting from a masterpage. Now when you put exactly the same code into a website which inherits from a masterpage, the UpdatePanel wouldn't get fired anymore.
I am calling a web service via Javascript. I tried it first in a web page that does not have a Masterpage and it worked perfectly. Then I moved everything over to a web page that does use a Masterpage, and I get a "Microsoft JScript runtime error: Object required" on the javascript statement that calls the web service. My javascript statements look like so:
I've got two linkbuttons on a masterpage. It works fine on all pages apart from page I have a form where if I click on one of the link buttons, then the wrong javascript event is fired. It is firing the button on the form if I click on the button on the masterpage.
