c# winform DataGridTextBoxColumn里加入CheckBox 问题???

楼主accpyy（小小鸟儿）2006-03-08 18:35:06 在 .NET技术 / C# 提问

GridColumnStylesCollection colStyle = datagrid名.TableStyles[0].GridColumnStyles;
//在第一列加入一个复选框
DataGridTextBoxColumn dgMaterial = (DataGridTextBoxColumn)colStyle[1];

ComboBox cb_Check;
cb_Check.Dock = DockStyle.Right;
cb_Check.BackColor = Control.DefaultBackColor;
cb_Check.Width = 25;
cb_Check.SelectedIndexChanged += new EventHandler(cb_Check_IndexChange);

dgMaterial.TextBox.Controls.Clear();
dgMaterial.TextBox.Controls.Add(cb_Check);

这样把控件加进去后，显示的不是控件而是true或false值，不知道大家遇到过同样的问题没有，请大家帮忙解决! 问题点数：100、回复次数：10Top

1、可以在表中加一个bool类型的字段
2、可以增加一个表，只有一行一列，bool类型的，然后和你现在的表联合查询就可以，

// code assumes you have a DataSet named myDataSet, a table named "EastCoastSales" and a DataGrid myDataGrid
//STEP 1: Create a DataTable style object and set properties if required.
DataGridTableStyle ts1 = new DataGridTableStyle();
//specify the table from dataset (required step)
ts1.MappingName = "EastCoastSales";
// Set other properties (optional step)
ts1.AlternatingBackColor = Color.LightBlue;
//STEP 2: Create a string column and add it to the tablestyle
DataGridColumnStyle TextCol = new DataGridTextBoxColumn();
TextCol.MappingName = "custName"; //from dataset table
TextCol.HeaderText = "Customer Name";
TextCol.Width = 250;
ts1.GridColumnStyles.Add(TextCol);
//STEP 3: Create an int column style and add it to the tablestyle
//this requires setting the format for the column through its property descriptor
PropertyDescriptorCollection pdc = this.BindingContext
[myDataSet, "EastCoastSales"].GetItemProperties();
//now created a formated column using the pdc
DataGridDigitsTextBoxColumn csIDInt =
new DataGridDigitsTextBoxColumn(pdc["CustID"], "i", true);
csIDInt.MappingName = "CustID";
csIDInt.HeaderText = "CustID";
csIDInt.Width = 100;
ts1.GridColumnStyles.Add(csIDInt);
//STEP 4: Add the checkbox
DataGridColumnStyle boolCol = new DataGridBoolColumn();
boolCol.MappingName = "Current";
boolCol.HeaderText = "Info Current";
//uncomment this line to get a two-state checkbox
//((DataGridBoolColumn)boolCol).AllowNull = false;
boolCol.Width = 150;
ts1.GridColumnStyles.Add(boolCol);
//STEP 5: Add the tablestyle to your datagrid's tablestlye collection
myDataGrid.TableStyles.Add(ts1);Top
