Hi
I have an event for the onrow databound
When I try and find one of the controls using
HyperLink hyp5 = ((HyperLink)e.Row.FindControl("hl"));
it shows an object reference error.
However when I use:
for (int x = 0; x < GridView4.Rows.Count; x++)
{
GridViewRow row = GridView4.Rows[x];
HyperLink hyp = ((HyperLink)row.FindControl("hl"));
it works. The problem is, it is slowing my app down by using the second method. How can I find the control using the first method?
thnaks.

I believe that a GridView row can be accessed only by using GridViewRow. For eg:
foreach (GridViewRow gvr in GridView1.Rows)
{
CheckBox cb = (CheckBox)gvr.FindControl("chkbox1");
if (cb.Checked)
{
string Username = gvr.Cells[1].Text;
}
}. This will work. But if you didn't use a GridViewRow object, you will not get the cell text of a particular row. Hope this helps.
Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

Thanks for replying, however I have another question now:
If I have an event using onrowdatebound, how can I access the current datakey for the row?
Ive tried
for (int x = 0; x < GridView4.Rows.Count; x++)
{
string ref2 = GridView4.DataKeys[x].Values[1].ToString();
but is there a way to get it using e.row?
The reason is I dont want to have to run a loop in my rowdatabound event.
thanks

Hi
I want to Add/update nodes in xml file using javascript.....

hi
yes it's possible.
i tell you that if you use asp.net it's better to use it's features for manipulating XML docs.
using this function you can load a xml file in your HTML document.
//javascript function code for loading XML doc
function loadXMLDoc(dname)
{
var xmlDoc
// code for IE
if (window.ActiveXObject)
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM")
}
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation && document.implementation.createDocument)
{
xmlDoc=document.implementation.createDocument("","",null)
}
else
{
alert('Your browser cannot handle this script'+'<br>Reason: Your browser does not support XML document')
}
xmlDoc.async=false
try
{
xmlDoc.load(dname)
}
catch(err)
{
alert("When loading XML document one error occured\nError: "+err)
return(null)
}
return(xmlDoc)
}
after loading XML doc you can use XML DOM for manipulating.
for more information about XML DOM visit http://www.w3schools.com/dom/default.asp
bye.

hi
using javascript code you can manipulate XML doc in client computer not server computer
if you want to manipulate XML doc on server computer you must use a server side programing
javascript is a client-side programing language.
do you use ASP.NET?
I don't know where is your XML doc? in Client computer or server computer.
plz answer this question.

I have an intranet web based applicaion(ASP.NET 2.0) for HR and employees called TRS.
There is a single sign on,i.e. your email id windows id and TRS id are made same at the time of creation.
The users cliclks on a link and the foloowing method is done to sign him in:
1.I Pick up his windows id
2.Check for the same ID in TRS Database as ID's are same.
3.If found log him in and show the default welcome screen.
This worked fine as long as the application was on intranet.
But now IT has provided Aventail VPN log in from where users access their email i.e. Outlook webmail and TRS also.
The problem lies here,
When you authenticate and enter the VPN session you can access all other application and Outlook.
When TRS is clicked a dialog box opens for user name and password in which you have to provide your windows user name id and password for your company.
Then if the credentails are correct you are shown the welcome page.
<b>The problem is that the dialog box is not required.</b>
Can anyone guide me as to how to do this i.e pick the user name from which the user logged inside VPN
Outlook opens directly once you enter the VPN session.
In the same way the site should get opened once authenticated to VPN and another dialog box for user name and password should not come.
Thanks in advance.
The authentication I currently use is windows authentication.
The code to fetch user name is:
Dim usernames() As String
userName = Request.ServerVariables("AUTH_USER")
The web config file is :
<authentication mode="Windows"/>
<identity impersonate="false"/>
<authorization>
<deny users="?"/>
</authorization>

Use this in the Code behind
ClientScript.RegisterClientScriptInclude("ScriptFile", ResolveClientUrl("~/JScript.js"));

Save a variable in view state and increment it on every time user clicks login button. Check in on page load and thats it.
Another way around is to keep a hidden field and store value in it.
Yet another way is to make a variable in a class and increment that.

That's not dirty way.

Client side values will be cleared when user closes the browser. So user can enter the login details again in a new browser window.
Keep a column in database which can be used to indicate the number of tries. When login fails, increment this number. If it is more than the allowed number, say user that your account is blocked.

Hi coders,
I am using .NET 3.5 framework. I'm working on a file upload project. What I want to do is give the user the ability to enter a directory name, check to see if it already exists and if not create the folder and upload the files their.
What namespaces should I be using? Am I correct in presuming the directory that will house these "user-created directories" will need to have write permissions assigned to it?
Thanks for any help in advance.

If(!Directory.Exists(path))
Directory.Create(path)

No. The directory that you create will by default get the same permissions as the parent folder. If you have permission to create the folder, you already have write permission.
Despite everything, the person most likely to be fooling you next is yourself.

It will be tough to maintain your application's file system if you have many directories created by users. I'd suggest keeping uploaded files in same location, and use URL rewriting which will give a feeling that the files are in specified directory.
