how to set checkboxes in datagrid in windows mobile 6 using c #?

dataset 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;

Here is the code from and Eric Hartwell's old blog (pulled into SO using a return path 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 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 }

To improve the appearance of the user interface, not a large cross

 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); } } }
