asp.net with vb.net

推荐答案

如果在单击列标题时问题需要知道列的索引和名称，则使用Window Form的答案(VB.Net)将通过符合事件签名的方法来处理ColumnHeaderMouseClick事件(请参见示例).

例如.假设DataGridView控制项是DataGridView1
私有子HeaderClick(按对象发送ByByVal，按System.Windows.Forms.DataGridViewCellMouseEventArgs处理ByVal e)处理DataGridView1.ColumnHeaderMouseClick
昏暗的col_index = e.ColumnIndex
昏暗的col_name = DataGridView1.Columns(col_index).Name
MessageBox.Show(String.Format("Index = {0}，Name = {1}"，col_index，
col_name))
结束Sub

If the question need to know the index and name of a column when its column header was clicked, then the answer for Window Form (VB.Net) is to handle the event ColumnHeaderMouseClick by a method which conform the event signature (seen the example).

Eg. Suppose that the DataGridView contol is DataGridView1
Private Sub HeaderClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick
Dim col_index = e.ColumnIndex
Dim col_name = DataGridView1.Columns(col_index).Name
MessageBox.Show(String.Format("Index={0}, Name={1}", col_index,
col_name))
End Sub
