How To Create a DataSet from Multiple Selected Rows in a DataGrid

This article describes how to create a DataSet from multiple selected rows in a DataGrid object.


I searched and searched the Internet for an easy way to take the rows that my users selected in a DataGrid and insert them into a DataSet or some other form of container that I could then make use of in my code. More specifically, when the user would sort and select multiple rows.

While I did find articles that helped, I came up short of the vision of creating an actual DataSet. One of these articles was off of The Code Project Web site published by Chad Z. Hower aka Kudzu called "Obtaining Current DataTable Row for a DataGrid". This was helpful if my users only selected one row but did not achieve the multi-row requirement.

I am not sure how advanced or basic this really is. All I know is that my searches kept coming up short. Since I am an avid user of code that I find on the Internet, I felt it was my moral obligation to give something back and that this was my chance to do so.


public static DataRow GetCurrentDataRow(DataGrid aGrid)

// Gets Currently Selected Row in a Datagrid.
CurrencyManager xCM = 
    (CurrencyManager)aGrid.BindingContext[aGrid.DataSource, aGrid.DataMember];
DataRowView xDRV = (DataRowView)xCM.Current;
return xDRV.Row;

public static ArrayList GetSelectedRowsArray(DataGrid aGrid)

//Returns an ArrayList containing the indexes of selected rows in a DataGrid 
   ArrayList al = new ArrayList(); 
   CurrencyManager cm = 
        (CurrencyManager)aGrid.BindingContext[aGrid.DataSource, aGrid.DataMember]; 
   DataView dv = (DataView)cm.List; 
   for(int i = 0; i < dv.Count; ++i) 
   return al; 

GetSelectedRowsDataSet(DataGrid aGrid)

//Returns a DataSet containing information for selected rows of a DataGrid.
   //DataSet and DataTable objects used in creating the new DataSet. 
   DataSet ds = new DataSet(); 
   DataTable table = new DataTable(); 
      //Use the CurrencyManager to create a data view so that you can 
      //use this to create the table schema. 
      CurrencyManager cm = 
        (CurrencyManager)aGrid.BindingContext[aGrid.DataSource, aGrid.DataMember]; 
      DataView dv = (DataView)cm.List; 
      //Add columns from dataview to table 
      foreach(DataColumn col in dv.Table.Columns) 

      //Using the GetSelectedRowsArray function loop through each of the selected 
      //row indexes setting the CurrentRowIndex property of your grid. Then import 
      //the current row using the GetCurrentDataRow function. 
      foreach(int i in GetSelectedRowsArray(aGrid)) 
         aGrid.CurrentRowIndex = i; 
      //Add your new table to the DataSet and return it. 
      return ds; 
   catch (System.Exception se) 
      //Error has occurred 
      throw se; 

Anyway, I hope this is helpful. Any ideas on how to improve would be helpful. Thanks and happy coding.

Thanks a million for this and it works absolutely fine. I had not heard of the currencymanager and was searching for this. I know we should be using the datagridview now (since VS2005?) but I am also using tablestyles in my grids so this one is perfect. Now to read up on the currencymanager or maybe work out how the datagridview works.....
