Don't write whole sentences in bold. It serves no purpose other than making it harder to read.

What you are using is not Java at all, it's Javascript.

DineshSharma wrote:

Standard question #1:
What do you mean by "not working"?

The Page object (that "this" references to) is the page itself, not a control on the page, so you can't add attributes to it. So I assume that the error message is that the object doesn't have any "Attributes" property.

Put an id on the body tag and make it a server tag, so that you can access it from code behind:

<body id="Body" runat="server">

Now you can declare the reference and put the call to the Javascript in the onload event:

protected HtmlGenericControl Body;<br />
<br />
Body.Attributes.Add("onload", "setObj('Dinesh','Sharma',550,30)");

Until now I'm setting the Control page like this:
<%@ Register TagPrefix="Menu" TagName="Bottom" Src="Bottom.ascx" %>
On the top of the page.

But now I need to set the Src dynamicly.
eg.: <%@ Register TagPrefix="Menu" TagName="Bottom" Src="Session["ID"] + "/Bottom.ascx" %>
Something like this.

Now I know that this is not how to do it, but maybe you can help me?

Problem in using PreviousPage Property [modified]

Hi,

I am using asp.net 2.0. In this,i am using Cross Page Posting. From the second page, i am trying to reference a control (Label) in the prevoius page using 'PreviousPage' property.

Here, in the first page, that Label control is placed within the <asp:Content> tag. (ie I am using MasterPage's ContentPlaceHolder).

Page.PreviousPage.FindControl("lebelid") method return null.

I am tried with refering the NamingContainer before refering the actual control (Label), which is placed within that NamingContainer. It also gives me the output null.

In my previous page, the Label control present within the tag,

<asp:Content ID="Content5" ContentPlaceHolderID="BodyContent" Runat="Server">

</asp:content>

In my second page (using same masterpage) code behind file, i am refering like this,( in Page_Load event)

ContentPlaceHolder myContent = (ContentPlaceHolder)Page.PreviousPage.FindControl("BodyContent");

Still it returns null.

Can anyone help me in this? Thanks in advance.

Regards,

Jay

It represents the MasterPage at runtime which in nature is the user control. If you set the Trace="true" in the first page, the control hierarchy of the trace info will give you some ideas.

Hi Nigam,

In the Datagrid try with this Code.

//set the action to handle the contextmenu
function oncontextmenu(event)
{
event.cancelBubble = true;
event.returnValue = false;
this.action("contextmenu");
}
// assign the event handler to the cell template prototype
Active.Templates.Text.prototype.setEvent("oncontextmenu", oncontextmenu);

// create action handler for the right click context menu
grid.setAction("contextmenu", function(src){ showmenu(event,getMenuHeader()+menu);return false;});

I hope this will works.

Happy Coding Smile | :)

Hi,
Why dont you use ItemDataBound event ? You can validate each and every cell in there and that too without help of javascript.
I hope i got your point !

You could use the timer control in Anthem.net.

Anthem.NET[^] is a free, cross-browser AJAX toolkit for the ASP.NET development environment that works with both ASP.NET 1.1 and 2.0

You could also download the package from this direct link:
http://superb-west.dl.sourceforge.net/sourceforge/anthem-dot-net/anthem-1.3.1.zip[^]

Hope this solves your problem

hello thanx for replying me.

when i download the zip of anthem example then its not openning it into the dotnet 2003.

is it done by ajax in this example.
thanx

hi again;

The zip file is the whole anthem project,after you have unzipped the file you got to open it's .net 2003 solution or project file in .net and then compile the project. From there you end up with a .dll file which you should use in your own project.

You have to import the .dll file as reference and in your toolbox as Anthem Tab.
Now you could use the timer control and solve your problem.

Hope the guide would be helpfull

Store the words as text along with the sound data, so that you can search that.
