Hi Anuradha I hope you can obtain your orginal datatable from your XML file. Then you can pivot that datatable and bind it to the datagridview. I found a good exmple on the web. I modified it a bit and uploaded. Check it. And use it for your application. If you find this answer useful please tick ' Do you like this answer' checkbox.

Hi niki In my app i use an xml file to populate the data grid view. How do i apply the Pivot and unpivot concept to my need? I have here a piece of my method that populates the data grid view .. May be it helps u understand my query better . HEre in my datagrid view i have column headers for BaudRate and Physical MEdia . They must now appear as row headers in place of column headers public void PopulateGrid( DataSet dataSets String tableName) { InitializeComponent(); int countOfColumns = 0; DataGridViewColumn [] gridColumns = null ; this .dataSet = dataSets; bindingSource.DataSource = dataSets.Tables[tableName]; this .DataMember = CommunicationDescription ; countOfColumns = dataSet.Tables[tableName].Columns.Count - 1; gridColumns = new System.Windows.Forms. DataGridViewColumn [countOfColumns]; for ( int i = 0; i { String appendText = dataSet.Tables[tableName].Columns[i].Caption; switch (appendText) { case PhysicalMedia : { DataGridViewComboBoxColumn column; column = ( DataGridViewComboBoxColumn ) new System.Windows.Forms. DataGridViewComboBoxColumn (); column.Items.Add( Ethernet ); column.Items.Add( RS232 ); column.DataPropertyName = dataSet.Tables[tableName].Columns[i].Caption; column.HeaderText = dataSet.Tables[tableName].Columns[i].Caption; column.Name = appendText + DataGridViewColumn ; gridColumns[i] = column; } break ; case BaudRate : { DataGridViewComboBoxColumn column; column = new System.Windows.Forms. DataGridViewComboBoxColumn (); column.Items.Add( 4800 ); column.Items.Add( 9600 ); column.Items.Add( 19200 ); column.Items.Add( 57600 ); column.DataPropertyName = dataSet.Tables[tableName].Columns[i].Caption; column.HeaderText = dataSet.Tables[tableName].Columns[i].Caption; column.Name = appendText + DataGridViewColumn ; gridColumns[i] = column; } break ; }

Hi Anuradha You can do that using pivot table. Let's say for your datagridview you bind data from following query. 'Select * from Employee'. Now if you want to interchange your rows and columns of your datagridview you should write a query to get the pivot table of your previous query. Then you can directly bind it to your datagridview. It will show interchanged rows and columns. To get an idea of how to get a pivot table you can go to following link. It has exmples. Click here. If you have any problem please ask.
