I have tried Your code, but it still does not work....listview freezes , but i have a question that the cross thread exception can be overcome by "Control.CheckForIllegalCrossThreadCalls=false " which given by windows form control ....is the problem comes only for cross thread exception ?

you can use
dataGrid1.Items.RemoveAt(dataGrid1.SelectedIndex);

or you can use
var dg = dataGrid1.CurrentItem as DataRowView;
string deleteFilePath = dg[0].ToString();

After inserting, you must call bindgrid() method in button1_click().

After insert or delete operation you can perform select query , so that whatever changes have done in database, may show in User Interface also

i have already try to check for the duplicate entry before inserting , code was
listView1.FindItemWithText(string)

but it falls , thats why i need a function which behaves like Distinct() method [in List Control ] ?

Is there any method of that kind?

in windows 7 the above code does not working. The hosts file does not allow to modify itself.......Please provide another solution. This may be working in windows xp but only for internet explorer..

thanks for your suggestion but i want to use different loop . because i have two threads . by first thread one listview will add items(even no.) and by second thread another listview will add items(square of those even no.). and i want to run these two process parallely . What i have to do ?

In the application when the user will run the program i will check some information ( like Mac address) , and kept it inside the file , and make it non editable because for second time i have to check user authentication from the data of that text file . it is important to my application . if the file is editable then user can easily edit the file and my application will not work properly

string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string filepath = path + "\\myfile.xyz";

File.WriteAllText(filepath, "Hi..");

i have done this code......
here in desktop the file can be easily opened by notepad

the point is clear to me but one more question i have that if i want to make the file non editable then what i have to do ?

but if the file is opened by notepad then it easily opens , how can i prevent it

one more question is how could you divide two columns and give them to their particular tasks without written any back end code means in datagrid , two columns (one is File Name and another is Directory Name) contain values of File and Directory_Path respectively but where you assign that Name_Column could contains only name of file and Directory_Column could contains only Directory_path ?
Please Explain ?

actually i am new in WPF ,can not implement such type of codes.
i want to show all temporary files in one datagrid .

my code is

FileInfo[] files = new DirectoryInfo(System.IO.Path.GetTempPath()).GetFiles();
foreach (FileInfo fi in files)
{
if (fi != null)
{
//here i want to add files(as rows ) in datagrid
}
}

which code is needed to bind rows in datagrid dynamically ? please help..

here i can not apply data binding approach. Please provide another solution ....

Thank You...

can i see this EnableRowVirtualization property on the properties window of Datagridview

Thanks for suggestion ....

Thank you..

Yeah yes work....
but can you explain why it does not work if it starts from first(1st) position

But my question is if it does not check the condition then how you set the value of i.
at first you have to fulfill the condition then you can go inside of the loop other wise it still shows
Convert.ToBoolean(dataGridView1.Rows[i].Cells[1].Value) = null

My Project is Windows Desktop Application based.....Please provide another code.

Yes its done ....
Thanks a lot........
Thank You Very much once again.....

Actually I want to delete empty folders. That's why here i try to check any folder contains any file or not. and if it contains empty file then the folder will be deleted. and my code is
string Spath2=Spath +@"\"+fj;
// Spath is a directory path and fj is the name of my textfile
if (Spath2.Length== 0) //Here it shows Length=27
{
Directory.Delete ( Spath, true);
}
but my textfile does not contain any data,thats why it shows 0 byte when i check it manually by mouse click .but in my code it shows 27 bytes when i Debug it. Why it shows Length is 27?
