    In this blog we are going to illustrate how to transfer the GridView data to DataTable.

    To transfer GridView to DataTable:

    We add button in .aspx page where the GridView display the data. By clicking this button user transfer the GridView data to DataTable.

    Code for .aspx page:

    
     <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
      <Columns>
          <asp:BoundField DataField="EmpId" HeaderText="EmpId" ItemStyle-Width="30" />
          <asp:BoundField DataField="EmpName" HeaderText="EmpName" ItemStyle-Width="150" />
          <asp:BoundField DataField="EmpAddress" HeaderText="EmpAddress" ItemStyle-Width="150" />
      </Columns>
     </asp:GridView>
     <br />
     <br />
      <asp:Button runat="server" ID="btn" OnClick="TransferDataToDataTable" Text="Transfer to Datatable" />

     

    Add the following Namespaces:

    using System.Data;
    using System.Configuration;
    using System.Data.SqlClient;

     

    Binding the GridView

    In page Load , GridView will display the data of employees table inside the Employee_system_database

     protected void Page_Load(object sender, EventArgs e)
     {
     if (!this.IsPostBack)
      {
        string ConnectString = ConfigurationManager.ConnectionStrings["ConnectString"].ConnectionString;
        using (SqlConnection con = new SqlConnection(ConnectString))
         {
          using (SqlCommand cmd = new SqlCommand("SELECT EmpId, EmpName, EmpAddress FROM Employees"))
                 {
              cmd.Connection = con;
        using (SqlDataAdapter sd = new SqlDataAdapter(cmd))
        {
        DataTable dt = new DataTable();
        sd.Fill(dt);
        Gridview.DataSource = dt;
        Gridview.DataBind();
        }
       }
       }
      }
     } 
    
    
       

     

     Transfer the data from GridView to DataTable in ASP.Net

    When a user clicked the “Transfer to Datatable “ button then data display in gridview will transferred into the datatable.

    protected void TransferDataToDataTable(object sender, EventArgs e)
     {
      DataTable EmployeeDataTable = new DataTable("Employees");
        foreach (TableCell cell in Gridview.HeaderRow.Cells)
       {
      EmployeeDataTable.Columns.Add(cell.Text);
       }
          foreach (GridViewRow row in Gridview.Rows)
        {
            EmployeeDataTable.Rows.Add();
       for (int i = 0; i < row.Cells.Count; i++)
        {
       EmployeeDataTable.Rows[row.RowIndex][i] = row.Cells[i].Text;
        }
        }
      }
