Question

how to put 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);

Here's some code from and old blog by Eric Hartwell (pulled into SO using 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
}

For better checkbox UI look and feel, rather than big 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);
}
}
}
