How to write Gridview data to XML file in .NET


One my colleague asked me yesterday , how we could save the Grid View Data to XML File, just i think come to this point and share with you.

Just Read data from the Grid View to DataSet, then we need write that dataset ti XML file.


DataSet ds = new DataSet("TestDataset");
DataTable dt = new DataTable("TestDataTable");
dt.Columns.Add("Id", System.Type.GetType("System.String"));
//Add any number columns here
for (int count = 0; count < GridView1.Rows.Count; count++)
DataRow dr = dt.NewRow();
dr[0] = GridView1.Rows[count].Cells[0].Text;
//you can add values to all columns in datatable


Dim ds As New DataSet("TestDataset")
Dim dt As New DataTable("TestDataTable")
dt.Columns.Add("Id", System.Type.[GetType]("System.String"))
'Add any number columns here
For count As Integer = 0 To GridView1.Rows.Count - 1
Dim dr As DataRow = dt.NewRow()
dr(0) = GridView1.Rows(count).Cells(0).Text
'you can add values to all columns in datatable

That's it

Thank you

Hi Guys,

Following code support to search types file with in the Directory including sub directories also.

public class FileSearch
ArrayList _extensions;
bool _recursive;
public ArrayList SearchExtensions
get { return _extensions; }
public bool Recursive
get { return _recursive; }
set { _recursive = value; }
public FileSearch()
_extensions = ArrayList.Synchronized(new ArrayList());
_recursive = true;
public FileInfo[] Search(string path)
DirectoryInfo root = new DirectoryInfo(path);
ArrayList subFiles = new ArrayList();
foreach (FileInfo file in root.GetFiles())
if (_extensions.Contains(file.Extension))
if (_recursive)
foreach (DirectoryInfo directory in root.GetDirectories())
return (FileInfo[])subFiles.ToArray(typeof(FileInfo));

How to Use:

FileSearch fileser = new FileSearch();
fileser.Recursive = true;
FileInfo[] dirRar = fileser.Search("D:\\test");
