Hi
I have a simple masterpage setup going. With a default "form1" form in the masterpage and a "hdnProvinceHTML" HTML hidden input control in one of the content pages.
The same content page has a block of JavaScript that needs to access the value of the hidden control.
alert(form1.hdnProvinceHTML.value) tells me that the controls are undefined.
If I look at the source of the running page I see that .Net has changed the names of my controls, and calling
alert(document.aspnetForm.ctl00$mainContentPlaceHolder$hdnProvinceHTML.value);
works.
Is there a way around this? What are the odds that .Net will always asign those names to the controls? And why is this happening in the first place?
Thanks a lot for any help...

Those names represent the control in the hierarchy of controls. Meaning the controls inside which your control is present. The odds that the name will be the same depending on the control mostly. It is not good practice to hardcode the names into the javascript. What you could do is register a call to the javascript function from codebehind.
You can get the full name of the control that will be registered in the page, by calling controlname.ClientID. So you could register in your codebehind something like
RegisterClientScriptBlock("genericname","alert(" + hdnProvinceHTML.ClientID +");")

Thanks, I'll certainly give it a try...
But ofcourse I have been yanked from that project to "quickly have a look at and fix a bug" in another project, so I don't know when I'll get around to it... grrr

Well, the idea is that you can get the ID that is generated in the browser by calling the controlname.ClientID method. From there you can call a javascript function passing the name as a parameter, and get a javascript refernce for the control with getElementById('clientsidename') that return the object. You can perform any operations on it from that point on.
Good luck with bugfixing.

Hi all,
I have installed VS.net 1.1 on a machine running Windows XP. Whenever I create a new web application it always throw error - Access to the path "c:\windows\microsoft.net\framework\v1.1.4322\Temporary ASP.NET Files\webapplication2\37f71cbe\939c5907" is denied.
I have also excluded "c:\windows\microsoft.net\framework\v1.1.4322\Temporary ASP.NET Files" folder from indexing services but same problem continues. When I go in folder "c:\windows\microsoft.net\framework\v1.1.4322\Temporary ASP.NET Files" there is no other folder or file except Bind Logs which is also empty.
Waiting for your valuable ideas.
Thanks
God help those who help others

Hi,
I have a dategrid were i have a link button for delete.
In the item data bound i am adding an onclick atribute for the link button to popup the msgbox. In Item command I am writing the logic for delete..
the columns in the grid are dynamically created from the codebehind and not in the design part...
My problem is when I click the delete link I am geting the msgbox..If I click ok the page is not posted back to the server and the row is also not deleted...
in Item data bound the code is :
((LinkButton)e.Item.Cells[9].Controls[0]).Attributes.Add("onclick","javascript:return ConfirmDelete();");
the javascript added in the .aspx part is :
function ConfirmDelete()
{
if(confirm('Do You Want to Delete?'))
{
return true;
}
return false;
}

The code seems to correct to me. I think the page should get postback.

Hi Members,
I got one requirements from my client.
We have functionality to send the mail from various formats.
My client gave the various structure of email content. So we can use this structure to send the mail from those templates and some of value from SQL Server DB Tables.
So I like to send the mail message from XML Document Message, so that client can change the message content at times as it requires.
So how can I precede the Email Template using XML in ASP.NET 2.0 using C#.
Can you any one helps me with sample code?
With Regards

Hi guys,
can anyone help me with this,
I need to browse the folders ,the sub folders of a directory on a machine and find all the pdf files.
Thanx
|
|
|
|

This works in C#, should work in ASP.NET in the machine also.
using System.IO;<br />
<br />
FileInfo[] FI = new DirectoryInfo(strDir).GetFiles("*.pdf", SearchOption.AllDirectories);
This will search in the sub dirs also.
good-luck.
NaNg.

Hi,
you can use the DirectoryInfo and FileInfo classes for this. Use for each statements to iterate through Files collection of DirectoryInfo class and also apply the same logic for each directory under the main directory.
This would definetly do the trick ( i think )

1. I'm looking for a way to detect from where the surfer is from.
I know google has such a thing and they can tell me from what country, region and even city I live in.
I know that in C# it something with colture.
How can I do it in ASP.NET?
2. I have an ASP.NET page, that opens a new ASP.NET page with a js cmd (window.open()).
How can I refresh the first page, when the second one closes? do I need to use a different cmd?

You can easily get the IP of the "surfer". From this IP you can get the location of the client.
Try reading the link below. Here are some tips.

here my problem is i need to display records of next,previous.if i click previous it should show upto first record like that.
using datagrid and repeater or anything else

You need to store the data in the dataset and just have to navigate the recordset according to the navigation button clicks.

Dim ds As New DataSet
Dim cmddtr As SqlDataAdapter
Dim cmdselect As SqlCommand
//opening connection
cmddtr = New SqlDataAdapter("select * from Division where Divi_id=7", dbconn)
cmddtr.Fill(ds, "Division")
DG.DataSource = ds
DG.DataMember = "Division"
DG.DataBind()
dbconn.Close()
This will work for a all the records to be display,but my need is ,when i click on buttonnext,it should show one by one record in the datagrid.no need of at a time all the records display,but each time when i click next it should go for the next record.likewise previous.

If you want to use a datagrid then you can go for paging and there you can set the page size to 1. That way you will get the one record per page and then navigation links.

i have this code placed on itemcommand of the datagrid..
<br />
If (e.Row.RowType <> DataControlRowType.Pager And e.Row.RowType <> DataControlRowType.Header) Then<br />
msClientCode = e.Row.Cells(1).Text<br />
msClientName = e.Row.Cells(2).Text<br />
msClientType = e.Row.Cells(3).Text<br />
End If<br />
how do i convert it to a gridview?
what should i use rowcommand or rowbound?
the code simply gets the selected item then puts the values of the fields into the variables..
anyone knew how to?
thanks..
