Question

cách đặt hộp kiểm trong DataGrid trong Windows Mobile 6 bằng cách sử dụng C#?

tập dữ liệu dsAgent = table; DataTable dataTable = dsAgent.Tables [0];

  DataGridTableStyle tableStyle = new DataGridTableStyle(); 

      tableStyle.MappingName = dataTable.TableName; 

      GridColumnStylesCollection columnStyles = tableStyle.GridColumnStyles; 

      DataGridTextBoxColumn columnStyle = new DataGridTextBoxColumn(); 
      columnStyle.MappingName = "FirstName"; 
      columnStyle.HeaderText = "Name"; 
      columnStyle.Width = 80; 
      columnStyles.Add(columnStyle); 

      //columnStyle = new DataGridTextBoxColumn(); 
      //columnStyle.MappingName = "EmailAddress"; 
      //columnStyle.HeaderText = "EmailID"; 
      //columnStyle.Width = 150; 
      //columnStyles.Add(columnStyle); 

      columnStyle = new DataGridTextBoxColumn(); 
      columnStyle.MappingName = "WorkPhone"; 
      columnStyle.HeaderText = "PhoneNo"; 
      columnStyle.Width = 150; 
      columnStyles.Add(columnStyle); 


      GridTableStylesCollection tableStyles = DataGrid.TableStyles; 
      tableStyles.Add(tableStyle); 


      DataGrid.PreferredRowHeight = 16; 
      DataGrid.RowHeadersVisible = false; 
      DataGrid.DataSource = dataTable;

Dưới đây là một số mã từ và blog cũ của Eric Hartwell (kéo vào SO sử dụng the wayback machine):

private void SetupTableStyles() 
    { 
     Color alternatingColor = SystemColors.ControlDark; 
     DataTable vehicle = dataSource.Tables[1]; 

     // ID Column 
     DataGridCustomTextBoxColumn dataGridCustomColumn0 = new DataGridCustomTextBoxColumn(); 
     dataGridCustomColumn0.Owner = this.dataGrid1; 
     dataGridCustomColumn0.Format = "0##"; 
     dataGridCustomColumn0.FormatInfo = null; 
     dataGridCustomColumn0.HeaderText = vehicle.Columns[0].ColumnName; 
     dataGridCustomColumn0.MappingName = vehicle.Columns[0].ColumnName; 
     dataGridCustomColumn0.Width = dataGrid1.Width * 10/100; // 10% of grid size 
     dataGridCustomColumn0.AlternatingBackColor = alternatingColor; 
     dataGridCustomColumn0.ReadOnly = true; 
     dataGridTableStyle1.GridColumnStyles.Add(dataGridCustomColumn0); 

     // Make column 
     DataGridCustomTextBoxColumn dataGridCustomColumn1 = new DataGridCustomTextBoxColumn(); 
     dataGridCustomColumn1.Owner = this.dataGrid1; 
     dataGridCustomColumn1.HeaderText = vehicle.Columns[1].ColumnName; 
     dataGridCustomColumn1.MappingName = vehicle.Columns[1].ColumnName; 
     dataGridCustomColumn1.NullText = "-Probably Ford-"; 
     dataGridCustomColumn1.Width = dataGrid1.Width * 40/100;  // 40% of grid size 
     dataGridCustomColumn1.Alignment = HorizontalAlignment.Right; 
     dataGridCustomColumn1.AlternatingBackColor = alternatingColor; 
     dataGridTableStyle1.GridColumnStyles.Add(dataGridCustomColumn1); 

     // Mileage column 
     DataGridCustomUpDownColumn dataGridCustomColumn2 = new DataGridCustomUpDownColumn(); 
     dataGridCustomColumn2.Owner = this.dataGrid1; 
     dataGridCustomColumn2.HeaderText = vehicle.Columns[2].ColumnName; 
     dataGridCustomColumn2.MappingName = vehicle.Columns[2].ColumnName; 
     dataGridCustomColumn2.NullText = "-Unknown-"; 
     dataGridCustomColumn2.Width = dataGrid1.Width * 20/100;  // 20% of grid size 
     dataGridCustomColumn2.Alignment = HorizontalAlignment.Left; 
     dataGridCustomColumn2.AlternatingBackColor = alternatingColor; 
     dataGridTableStyle1.GridColumnStyles.Add(dataGridCustomColumn2); 

     // Availability column 
     DataGridCustomCheckBoxColumn dataGridCustomColumn3 = new DataGridCustomCheckBoxColumn(); 
     dataGridCustomColumn3.Owner = this.dataGrid1; 
     dataGridCustomColumn3.HeaderText = vehicle.Columns[3].ColumnName; 
     dataGridCustomColumn3.MappingName = vehicle.Columns[3].ColumnName; 
     dataGridCustomColumn3.NullText = "-Unknown-"; 
     dataGridCustomColumn3.Width = dataGrid1.Width * 10/100;  // 10% of grid size 
     dataGridCustomColumn3.Alignment = HorizontalAlignment.Left; 
     dataGridCustomColumn3.AlternatingBackColor = alternatingColor; 
     dataGridTableStyle1.GridColumnStyles.Add(dataGridCustomColumn3); 

     // Fuel Level column 
     DataGridCustomComboBoxColumn dataGridCustomColumn4 = new DataGridCustomComboBoxColumn(); 
     dataGridCustomColumn4.Owner = this.dataGrid1; 
     dataGridCustomColumn4.HeaderText = vehicle.Columns[4].ColumnName; 
     dataGridCustomColumn4.MappingName = vehicle.Columns[4].ColumnName; 
     dataGridCustomColumn4.NullText = "-Unknown-"; 
     dataGridCustomColumn4.Width = dataGrid1.Width * 30/100;  // 30% of grid size 
     dataGridCustomColumn4.Alignment = HorizontalAlignment.Left; 
     dataGridCustomColumn4.AlternatingBackColor = alternatingColor; 
     dataGridTableStyle1.GridColumnStyles.Add(dataGridCustomColumn4); 

     // Last Used column 
     DataGridCustomDateTimePickerColumn dataGridCustomColumn5 = new DataGridCustomDateTimePickerColumn(); 
     dataGridCustomColumn5.Owner = this.dataGrid1; 
     dataGridCustomColumn5.HeaderText = vehicle.Columns[5].ColumnName; 
     dataGridCustomColumn5.MappingName = vehicle.Columns[5].ColumnName; 
     dataGridCustomColumn5.NullText = "-Unknown-"; 
     dataGridCustomColumn5.Width = dataGrid1.Width * 30/100;  // 30% of grid size 
     dataGridCustomColumn5.Alignment = HorizontalAlignment.Left; 
     dataGridCustomColumn5.AlternatingBackColor = alternatingColor; 
     dataGridTableStyle1.GridColumnStyles.Add(dataGridCustomColumn5); 

     // Grid, mapping 
     dataGridTableStyle1.MappingName = vehicle.TableName;      // Setup table mapping name 
     dataGrid1.DataSource = vehicle;         

     // Setup grid's data source 
     ComboBox cb = (ComboBox)dataGridCustomColumn4.HostedControl; 
     DataTable fuel = dataSource.Tables[0];             // Set up data source 
     cb.DataSource = fuel;            

     // For combo box column 
     cb.DisplayMember = fuel.Columns[0].ColumnName; 
     cb.ValueMember = fuel.Columns[0].ColumnName; 

     dataGrid1.CurrentRowIndex = 50;               // Move to the middle of the table 
    }

Đối với tốt hơn hộp kiểm UI cái nhìn và cảm nhận, chứ không phải là lớn chéo

private void DrawCheckBox(Graphics g, Rectangle bounds, CheckState state) 
     { 
      int size; 
      int boxTop; 

      size = bounds.Size.Height < bounds.Size.Width ? bounds.Size.Height : bounds.Size.Width; 
      size = size > ((int)g.DpiX/7) ? ((int)g.DpiX/7) : size; 

      boxTop = bounds.Y + (bounds.Height - size)/2; 
      size = 12; // 13, so I made it 12 
      boxTop = boxTop - 1; 
      using (Pen p = new Pen(this.Owner.ForeColor)) 
      { 
       g.DrawRectangle(p, bounds.X, boxTop, size, size); 
      } 

      if (state != CheckState.Unchecked) 
      { 
       using (Pen p = new Pen(state == CheckState.Indeterminate ? SystemColors.GrayText : SystemColors.ControlText)) 
       { 
        p.Width = 2; 
        int offset = 2; 
        int edgeOffset = 2; 
        g.DrawLine(p, bounds.X + offset, boxTop + offset + 2, bounds.X + (size/2) - edgeOffset, boxTop + (size/2) + edgeOffset); 
        g.DrawLine(p, bounds.X + (size/2) - edgeOffset, boxTop + (size/2) + edgeOffset, bounds.X + size - offset, boxTop + offset); 
       } 
      } 
     }
