DatagridView绑定DataTable的变态问题，别打我

    我在设计器里定好了DatagridView的表头，如何只取datatable里的数据和

DatagridView的列对应起来，而不是把整个datatable，包括列名都绑到其中。

------解决方案--------------------
通过设置DataPropertyName 属性来使列和数据源的列关联起来：

DataGridViewColumn.DataPropertyName 属性
获取或设置数据源属性的名称或与 DataGridViewColumn 绑定的数据库列的名称。

下面的代码示例演示如何选择各列将表示的属性。(MSDN)

private void EnumsAndComboBox_Load(object sender, System.EventArgs e)
{
// Populate the data source.
bindingSource1.Add(new Knight(Title.King, "Uther ", true));
bindingSource1.Add(new Knight(Title.King, "Arthur ", true));
bindingSource1.Add(new Knight(Title.Sir, "Mordred ", false));
bindingSource1.Add(new Knight(Title.Sir, "Gawain ", true));
bindingSource1.Add(new Knight(Title.Sir, "Galahad ", true));

// Initialize the DataGridView.
dataGridView1.AutoGenerateColumns = false;
dataGridView1.AutoSize = true;
dataGridView1.DataSource = bindingSource1;

dataGridView1.Columns.Add(CreateComboBoxWithEnums());

// Initialize and add a text box column.
DataGridViewColumn column = new DataGridViewTextBoxColumn();
column.DataPropertyName = "Name ";
column.Name = "Knight ";
dataGridView1.Columns.Add(column);

// Initialize and add a check box column.
column = new DataGridViewCheckBoxColumn();
column.DataPropertyName = "GoodGuy ";
column.Name = "Good ";
dataGridView1.Columns.Add(column);

// Initialize the form.
this.Controls.Add(dataGridView1);
this.AutoSize = true;
this.Text = "DataGridView object binding demo ";
}

DataGridViewComboBoxColumn CreateComboBoxWithEnums()
{
DataGridViewComboBoxColumn combo = new DataGridViewComboBoxColumn();
combo.DataSource = Enum.GetValues(typeof(Title));
combo.DataPropertyName = "Title ";
combo.Name = "Title ";
return combo;
}
#region "business object "
private class Knight
{
private string hisName;
private bool good;
private Title hisTitle;

public Knight(Title title, string name, bool good)
{
hisTitle = title;
hisName = name;
this.good = good;
}

public Knight()
{
hisTitle = Title.Sir;
hisName = " <enter name> ";
good = true;
}

public string Name
{
get
{
return hisName;
}

set
{
hisName = value;
}
}

public bool GoodGuy
{
get
{
return good;
}
set
{
good = value;
}
}

public Title Title
{
get
{
return hisTitle;
}
set
{
hisTitle = value;
}
}
}
#endregion



------解决方案--------------------
设置列的DataPropertyName 属性到你数据源的列名上就可以了
