Coding Problem:

Converting a Asp.Net GridView that has controls back into a data table

Real World Problem:

Google did not have any really useful answers I could find and implement

Asp.Net GridView:

<asp:GridView ID="gvCompanies" runat="server" AutoGenerateColumns="False" AllowSorting="True" OnSorting="gridView_Sorting">
            <Columns>
            <asp:TemplateField HeaderText = "Comapny Id"><ItemTemplate><%# Eval("Company Id")%></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "New Company Id"><ItemTemplate><asp:TextBox ID="TextBox5" runat ="server"></asp:TextBox></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "Company Name"><ItemTemplate><asp:TextBox ID="TextBox6" runat ="server"></asp:TextBox></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "Branch Id"><ItemTemplate><asp:TextBox ID="TextBox7" runat ="server"></asp:TextBox></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "Location Id"><ItemTemplate><asp:TextBox ID="TextBox8" runat ="server"></asp:TextBox></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "Location Name"><ItemTemplate><asp:TextBox ID="TextBox9" runat ="server"></asp:TextBox></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "Prefix"><ItemTemplate><asp:TextBox ID="TextBox10" runat ="server" ></asp:TextBox></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "Sort"><ItemTemplate><asp:TextBox ID="TextBox11" runat ="server"></asp:TextBox></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "Cash In Transit"><ItemTemplate><asp:TextBox ID="TextBox12" runat ="server"></asp:TextBox></ItemTemplate></asp:TemplateField>

            <asp:TemplateField HeaderText = "Cash Sub Account"><ItemTemplate><asp:TextBox ID="TextBox15" runat ="server"></asp:TextBox></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "Payment Method"><ItemTemplate><asp:TextBox ID="TextBox16" runat ="server"></asp:TextBox></ItemTemplate></asp:TemplateField>
            <asp:TemplateField HeaderText = "AppDB"><ItemTemplate><%# Eval("AppDB")%></ItemTemplate></asp:TemplateField>
            </Columns>
            </asp:GridView

Answer 1

Solution:

1. gvCompanies is the GridView
2. dtCompanies was the original DataTable

3. Can add more if else for different control types

   protected DataTable ConvertToDataTable()
   {
       DataTable TempTable = new DataTable();
       TempTable = dtCompanies.Clone();
   
       foreach (GridViewRow row in gvCompanies.Rows)
       {
            DataRow TempRow = TempTable.NewRow();
   
            for (int i = 0; i < row.Cells.Count; i++)
            {
                if (row.Cells[i].Controls[0].GetType().Equals(typeof(DataBoundLiteralControl)))
                {
                    TempRow[i] = ((DataBoundLiteralControl)row.Cells[i].Controls[0] as DataBoundLiteralControl).Text;
                }
                else if (row.Cells[i].Controls[0].GetType().Equals(typeof(TextBox)))
                {
                    TempRow[i] = ((TextBox)row.Cells[i].Controls[0]).Text;
                }
            }
            TempTable.Rows.Add(TempRow);
       }
       return TempTable;
   }
