急急急！在线等，Winform中DataGrid增加Checkbox选择列的问题（VS2003）

[insnowind]

我想在DataGrid中插入第一列作为选择列，这是我的代码，为什么显示不出来？
DataGridBoolColumn的MapingName属性是不是一定要，我这里只是作为选择标记，并不需要影射到某一列上，应该怎么做，看了很多文章都不行，高手救我！！！！

DataGridTableStyle ts = new DataGridTableStyle();

DataGridTextBoxColumn aColumnTextColumn;
DataGrid1.DataSource = dtGrid;
ts.MappingName = dtGrid.TableName;
int numCols = dtGrid.Columns.Count;
DataGrid1.CaptionText = "生产计划列表";

DataGridColumnStyle dcSelect = new DataGridBoolColumn();
dcSelect.HeaderText = "选择";
dcSelect.MappingName = "";
//dcSelect.Alignment = System.Windows.Forms.HorizontalAlignment.Center;
dcSelect.Width = 50;
//dcSelect.AllowNull = false;
ts.GridColumnStyles.Add(dcSelect);

How can I put a checkbox in a column of my DataGrid?

[insnowind]

myDb db1 = new myDb() ;
DataTable dtGrid = db1.ExecuteToDataTable(strSQL) ;

//=======================================
DataGridTableStyle ts = new DataGridTableStyle();

DataGridTextBoxColumn aColumnTextColumn;
DataGrid1.DataSource = dtGrid;
ts.MappingName = dtGrid.TableName;
int numCols = dtGrid.Columns.Count;
DataGrid1.CaptionText = "生产计划列表";

DataGridColumnStyle dcSelect = new DataGridBoolColumn();
dcSelect.HeaderText = "选择";
dcSelect.MappingName = "";//是不是这里的问题
dcSelect.Alignment = System.Windows.Forms.HorizontalAlignment.Center;
dcSelect.Width = 50;
dcSelect.AllowNull = false;
ts.GridColumnStyles.Add(dcSelect);

int loopFlag = 0;
while (loopFlag < numCols)
{
aColumnTextColumn = new DataGridTextBoxColumn();
switch (loopFlag)
{
case 0 :
aColumnTextColumn.HeaderText = "编号";
aColumnTextColumn.Width = 50;
break;
case 1 :
aColumnTextColumn.HeaderText = "市场名称";
aColumnTextColumn.Width = 200;
break;
case 2 :
aColumnTextColumn.HeaderText = "档位号码";
aColumnTextColumn.Width = 80;
break;
//其他的省略了
}
aColumnTextColumn.NullText = "";
aColumnTextColumn.ReadOnly = true;
aColumnTextColumn.Alignment=System.Windows.Forms.HorizontalAlignment.Center;
aColumnTextColumn.MappingName = dtGrid.Columns[loopFlag].ColumnName;
ts.GridColumnStyles.Add(aColumnTextColumn);
loopFlag++;
}

DataGrid1.TableStyles.Add(ts);

DataGrid1.TableStyles.Add(ts);

如果直接向DataGrid种进行插入，不设置Mapping是不行的。

替换做法，你创建一个临时列，用于显示Checkbox，而且这也不麻烦。

[insnowind]

myDb db1 = new myDb() ;
DataTable dtGrid = db1.ExecuteToDataTable(strSQL) ;

DataColumn checkCol = new DataColumn();
checkCol.ColumnName = "CheckState";
checkCol.DefaultValue = "0";
checkCol.AllowDBNull = false;

dtGrid.Columns.Add(checkCol);


//=======================================
DataGridTableStyle ts = new DataGridTableStyle();

DataGridTextBoxColumn aColumnTextColumn;
DataGrid1.DataSource = dtGrid;
ts.MappingName = dtGrid.TableName;
int numCols = dtGrid.Columns.Count;
DataGrid1.CaptionText = "生产计划列表";

DataGridColumnStyle dcSelect = new DataGridBoolColumn();
dcSelect.HeaderText = "选择";
dcSelect.MappingName = "CheckState";
dcSelect.Alignment = System.Windows.Forms.HorizontalAlignment.Center;
dcSelect.Width = 50;
((DataGridBoolColumn)dcSelect).AllowNull = false;
dcSelect.
ts.GridColumnStyles.Add(dcSelect);
===============================================================================
我这样做了之后，出来是出来了，为什么都是默认选中的灰色，而且点一下就会自动生成一个空的行，点一下多一个

[insnowind]

还是要靠自己整！

[insnowind]

主要是这几句：
DataGridColumnStyle dcSelect = new DataGridBoolColumn();
dcSelect.HeaderText = "选择";
dcSelect.MappingName = "";
//dcSelect.Alignment = System.Windows.Forms.HorizontalAlignment.Center;
dcSelect.Width = 50;
//dcSelect.AllowNull = false;
ts.GridColumnStyles.Add(dcSelect);

所有列定义完之后，还有这句：
DataGrid1.TableStyles.Add(ts);

所以应该是DataGridBoolColumn没有定义好，应该是怎么回事，谢谢！

[insnowind]

顶顶顶！

LZ这种插入方式更方便些:
private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if ((e.Item.ItemType == ListItemType.Item) ||
(e.Item.ItemType == ListItemType.AlternatingItem) ||
(e.Item.ItemType == ListItemType.SelectedItem) )
{
CheckBox cb ;
//加选择框
cb = new CheckBox();
e.Item.Cells[0].Controls.Add(cb);
}

[insnowind]

怎么没有这个事件呢？
ItemDataBound

小强说的不是winform

参考我以前做的嵌入datetimePicker
aColumnTextColumn.Width = 100;
DateTimePicker dtp = new DateTimePicker();
dtp.Dock= DockStyle.Fill;
dtp.Cursor= Cursors.Arrow;
dtp.ValueChanged+=new EventHandler(this.dtg_ValueChanged);//日期获取变化
aColumnTextColumn.TextBox.Controls.Add(dtp);

[insnowind]

aColumnTextColumn.Width = 100;
DateTimePicker dtp = new DateTimePicker();
dtp.Dock= DockStyle.Fill;
dtp.Cursor= Cursors.Arrow;
dtp.ValueChanged+=new EventHandler(this.dtg_ValueChanged);//日期获取变化
aColumnTextColumn.TextBox.Controls.Add(dtp);
=============================================================================
这样和那个有一点区别，这个是填充值，那个是这一列根本显示不出来，应该怎么做，请指教：）

[insnowind]

加点分！
