Datagrid sütun başlık metnimi nasıl değiştirebilirim ve güncellenmiş üstbilgiyi excel'de nasıl yazdırabilirim? i sqlite tabloda başlığını değiştirmek istemiyorum

Question

, ben sadece datagrid'e üzerinde değiştirmek istiyorum ve daha sonra excel dosyasında yazdırmak istediğiniz .... İşte benim XAML kodu

 <DataGrid.Columns> 
      <DataGridTextColumn Header="A" Width="100" Binding="{Binding A}"/> 

      <DataGridTextColumn Header="B" Width="100" Binding="{Binding B}"/> 
      <DataGridTextColumn Header="rr" Width="100" Binding="{Binding C}"/> 
      <DataGridTextColumn Header="D" Width="100" Binding="{Binding D}"/> 
      <DataGridTextColumn Header="E" Width="100" Binding="{Binding E}"/> 
      <DataGridTextColumn Header="F" Width="100" Binding="{Binding F}"/> 
      <DataGridTextColumn Header="G" Width="100" Binding="{Binding G}"/> 
      <DataGridTextColumn Header="H" Width="100" Binding="{Binding H}"/> 
      <DataGridTextColumn Header="I" Width="100" Binding="{Binding I}"/> 
      <DataGridTextColumn Header="J" Width="100" Binding="{Binding J}"/> 
      <DataGridTextColumn Header="K" Width="100" Binding="{Binding K}"/> 
      <DataGridTextColumn Header="L" Width="100" Binding="{Binding L}"/> 
      <DataGridTextColumn Header="M" Width="100" Binding="{Binding M}"/> 
      <DataGridTextColumn Header="N" Width="100" Binding="{Binding N}"/> 
      <DataGridTextColumn Header="O" Width="100" Binding="{Binding O}"/> 
      <DataGridTextColumn Header="P" Width="100" Binding="{Binding P}"/> 
      <DataGridTextColumn Header="Q" Width="100" Binding="{Binding Q}"/> 
      <DataGridTextColumn Header="R" Width="100" Binding="{Binding R}"/> 
      <DataGridTextColumn Header="S" Width="100" Binding="{Binding S}"/> 
      <DataGridTextColumn Header="T" Width="100" Binding="{Binding T}"/> 
      <DataGridTextColumn Header="U" Width="100" Binding="{Binding U}"/> 
      <DataGridTextColumn Header="V" Width="100" Binding="{Binding V}"/> 
      <DataGridTextColumn Header="W" Width="100" Binding="{Binding W}"/> 
      <DataGridTextColumn Header="X" Width="100" Binding="{Binding X}"/> 
      <DataGridTextColumn Header="Y" Width="100" Binding="{Binding Y}"/> 
      <DataGridTextColumn Header="Z" Width="100" Binding="{Binding Z}"/> 

     </DataGrid.Columns> 

ve ben istiyorum dataTabl için veri kılavuzunu dönüştürün cs dosyasında

Answer 1

private void Heder_A_Update_Click(object sender, RoutedEventArgs e) 
    { 
     var newHederText = MyTextBox.Text; 

     var temp = new DataTemplate(); 
     temp.VisualTree = new FrameworkElementFactory(typeof(TextBlock)); 
     temp.VisualTree.SetValue(TextBlock.TextProperty, newHederText); 
     dataGrid.Columns[0].HeaderTemplate = temp; 
    } 

Edit

1- metin kutusu ve düğmesini kullanarak değiştirmek e

public static DataTable GridToDataTable(DataGrid dataGrid) 
{ 
    DataView dView = (DataView)dataGrid.ItemsSource) 
    DataTable table= dView.Table.Clone(); 
    foreach (DataRowView dv in dView) 
     dt.ImportRow(dView .Row); 
    return table; 
} 

veya

var table= ((DataView)dataGrid.ItemsSource).ToTable(); 

2- Datatable vermek için uzatma yöntemi oluşturmak

public static void ExportToExcel(this DataTable dataTable, string excelFilePath = null) 
     { 
      try 
      { 
       int columnsCount; 

       if (dataTable == null || (columnsCount = dataTable.Columns.Count) == 0) 
        throw new Exception("ExportToExcel: Null or empty input table!\n"); 

       // load excel, and create a new workbook 
       var excel = new Microsoft.Office.Interop.Excel.Application(); 
       excel.Workbooks.Add(); 

       // single worksheet 
       Microsoft.Office.Interop.Excel._Worksheet worksheet = excel.ActiveSheet; 

       var header = new object[columnsCount]; 

       // column headings    
       for (int i = 0; i < columnsCount; i++) 
        header[i] = dataTable.Columns[i].ColumnName; 

       Microsoft.Office.Interop.Excel.Range headerRange = worksheet.Range[(Microsoft.Office.Interop.Excel.Range)(worksheet.Cells[1, 1]), (Microsoft.Office.Interop.Excel.Range)(worksheet.Cells[1, columnsCount])]; 
       headerRange.Value = header; 
       headerRange.Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.LightSkyBlue); 
       headerRange.Font.Bold = true; 

       // DataCells 
       int rowsCount = dataTable.Rows.Count; 
       var cells = new object[rowsCount, columnsCount]; 

       for (int j = 0; j < rowsCount; j++) 
        for (int i = 0; i < columnsCount; i++) 
         cells[j, i] = dataTable.Rows[j][i]; 

       worksheet.Range[(Microsoft.Office.Interop.Excel.Range)(worksheet.Cells[2, 1]), (Microsoft.Office.Interop.Excel.Range)(worksheet.Cells[rowsCount + 1, columnsCount])].Value = cells; 

       try 
       { 
        worksheet.SaveAs(excelFilePath); 
        excel.Quit(); 
       } 
       catch (Exception ex) 
       { 
        throw new Exception("ExportToExcel: Excel file could not be saved! Check filepath.\n" 
         + ex.Message); 
       } 
      } 
      catch (Exception ex) 
      { 
       throw new Exception("ExportToExcel: \n" + ex.Message); 
      } 
     } 

3- calling the method : 

geçmek için aşağıdaki işlevi kullanılarak 10

string filename = @"c:\temp\export.xlsx"; // 
table.ExportToExcel(filename); 

veya

GridToDataTable(datagrid).ExportToExcel(filename); 

Kontrol başlıkları sorun yoksa, aksi takdirde A" gibi Başlığını değiştirmek istediğiniz excel

başlığını

int index=1; 
foreach (var colName in dataGrid.Columns.Select(cs => cs.Header).ToList()) 
{ 
     excel.Cells[1, index] = colName.ToStrihng(); 
     index++; 
}
