[英]How to add a checkbox in my checkbox column using datagridview windowsform in VB.Net
Private Sub Recipients_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
mycom.Connection = cn
mycom.CommandText = <SQL> SELECT Idno,Name,YearSec,Course,Organization FROM tbl_students </SQL>.Value
Dim myadap As New MySqlDataAdapter(mycom)

我在我的复选框列的标题中创建一个复选框时遇到问题,该复选框应该是复选框,以便我可以检查数据gridview中存在的所有行。 任何答案都会有很大帮助。 谢谢
像这样尝试
DataGridViewCheckBoxColumn c1;
CheckBox ckBox;
grdRecipients.DataSource = mydt
ckBox = new CheckBox();
//Get the column header cell bounds
Rectangle rect =
this.dataGridView1.GetCellDisplayRectangle(0, -1, true);
ckBox.Size = new Size(18, 18);
//Change the location of the CheckBox to make it stay on the header
ckBox.Location = rect.Location;
ckBox.CheckedChanged += new EventHandler(ckBox_CheckedChanged);
//Add the CheckBox into the DataGridView
this.dataGridView1.Controls.Add(ckBox);
下面的方法用于选中取消选中所有复选框
void ckBox_CheckedChanged(object sender, EventArgs e)
{
for (int j = 0; j < this.dataGridView1.RowCount; j++)
{
this.dataGridView1[0, j].Value = this.ckBox.Checked;
}
this.dataGridView1.EndEdit();
}
