如何在cellclick上选择行，并在列标题上单击列？

您好我想通过点击列选择列，并通过点击单元格来选择行。

这段代码不能完成这项工作。

Private Sub datagridview2_ColumnHeaderMouseClick（sender As Object，e As DataGridViewCellMouseEventArgs）处理datagridview2.ColumnHeaderMouseClick datagridview2.Columns（e.ColumnIndex ）.Selected = True End Sub

这些gridview选项是我在代码

For Each c As DataGridViewColumn in datagridview2.Columns c.SortMode = DataGridViewColumnSortMode.NotSortable c.Selected = False Next datagridview2.SelectionMode = DataGridViewSelectionMode.FullRowSelect

我希望有人能帮忙。干杯b101

编辑：好的列和行选择工作fia标题点击。现在需要通过点击单元格来选择一个单元格。 以下代码有效，但有2次点击。第一次点击取消选择行或列，第二次点击选择单元格

Private Sub datagridview2_CellMouseClick（sender As Object，e As DataGridViewCellMouseEventArgs ）处理datagridview2.CellMouseClick datagridview2.SelectionMode = DataGridViewSelectionMode.CellSelect End Sub

如果我尝试通过e.columnindex e.rowindex 选择单元格点击事件中的卖出，它会引发异常情况。索引是完全愚蠢的像-1或一些相似的索引，但不存在。

编辑2：此代码不起作用

Private Sub datagridview2_CellMouseClick（sender As Object，e As DataGridViewCellMouseEventArgs）处理datagridview2.CellMouseClick datagridview2.SelectionMode = DataGridViewSelectionMode。 CellSelect datagridview2.Rows（e.RowIndex）.Cells（e.ColumnIndex）.Selected = True End Sub Private Sub datagridview2_ColumnHeaderMouseClick（sender As Object，e As DataGridViewCellMouseEventArgs）处理datagridview2.ColumnHeaderMouseClick datagridview2.SelectionMode = DataGridViewSelectionMode.ColumnHeaderSelect datagridview2.Columns （e.ColumnIndex）.Selected = True End Sub Private Sub datagridview2_RowHeaderMouseClick（sender As Object，e As DataGridViewCellMouseEventArgs）处理datagridview2.RowHeaderMouseClick datagridview2.SelectionMode = DataGridViewSelectionMode.FullRowSelect datagridview2.Rows（e.RowIndex）.Selected = True End Sub

当点击标题时，它会跳转到cellmouseclick事件中。

解决方案

Private Sub DataGridView1_ColumnHeaderMouseClick（sender As Object，e As DataGridViewCellMouseEventArgs）处理DataGridView1.ColumnHeaderMouseClick DataGridView1.SelectionMode = DataGridViewSelectionMode.ColumnHeaderSelect DataGridView1.Columns（e.ColumnIndex）.Selected = True End Sub Private Sub DataGridView1_RowHeaderMouseClick（sender As Object，e As DataGridViewCellMouseEventArgs）处理DataGridView1.RowHeaderMouseClick 如果e.ColumnIndex = -1并且DataGridView1.SelectionMode<> DataGridViewSelectionMode.RowHeaderSelect和DataGridView1.Rows（e.RowIndex）.Selected = False Then DataGridView1.SelectionMode = DataGridViewSelectionMode.RowHeaderSelect DataGridView1.Rows（e.RowIndex）.Selected = True End If End Sub Private Sub DataGridView1_CellClick（sender As Object，e As DataGridViewCellEventArgs）处理DataGridView1.CellClick 如果e.RowIndex> -1和DataGridView1.SelectionMode<> DataGridViewSelectionMode.CellSelect Then DataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect DataGridView1.CurrentCell.Selected = True End If End Sub

Hello I want to select the column via columnheader click, and also select the row via cell click.

This code doesnt do the job.

Private Sub datagridview2_ColumnHeaderMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles datagridview2.ColumnHeaderMouseClick datagridview2.Columns(e.ColumnIndex).Selected = True End Sub

these gridview options I made in the code

For Each c As DataGridViewColumn In datagridview2.Columns c.SortMode = DataGridViewColumnSortMode.NotSortable c.Selected = False Next datagridview2.SelectionMode = DataGridViewSelectionMode.FullRowSelect

I hope someone can help out. Cheers b101

Edit: well column and row select works fia header click. Now it is needed to select one single cell by cell click. The following code works, but with 2 clicks. the first click unselects row or column and the second click selects the single cell

Private Sub datagridview2_CellMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles datagridview2.CellMouseClick datagridview2.SelectionMode = DataGridViewSelectionMode.CellSelect End Sub

If I try to select the sell in the cell click event via e.columnindex e.rowindex it throws a outofrangeexception. the indexes are totally stupid like -1 or some simililar index wich doesnt exist.

Edit 2: This code doesnt work

Private Sub datagridview2_CellMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles datagridview2.CellMouseClick datagridview2.SelectionMode = DataGridViewSelectionMode.CellSelect datagridview2.Rows(e.RowIndex).Cells(e.ColumnIndex).Selected = True End Sub Private Sub datagridview2_ColumnHeaderMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles datagridview2.ColumnHeaderMouseClick datagridview2.SelectionMode = DataGridViewSelectionMode.ColumnHeaderSelect datagridview2.Columns(e.ColumnIndex).Selected = True End Sub Private Sub datagridview2_RowHeaderMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles datagridview2.RowHeaderMouseClick datagridview2.SelectionMode = DataGridViewSelectionMode.FullRowSelect datagridview2.Rows(e.RowIndex).Selected = True End Sub

When click on headers itjumps into cellmouseclick event

Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick DataGridView1.SelectionMode = DataGridViewSelectionMode.ColumnHeaderSelect DataGridView1.Columns(e.ColumnIndex).Selected = True End Sub Private Sub DataGridView1_RowHeaderMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles DataGridView1.RowHeaderMouseClick If e.ColumnIndex = -1 And DataGridView1.SelectionMode <> DataGridViewSelectionMode.RowHeaderSelect And DataGridView1.Rows(e.RowIndex).Selected = False Then DataGridView1.SelectionMode = DataGridViewSelectionMode.RowHeaderSelect DataGridView1.Rows(e.RowIndex).Selected = True End If End Sub Private Sub DataGridView1_CellClick(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellClick If e.RowIndex > -1 And DataGridView1.SelectionMode <> DataGridViewSelectionMode.CellSelect Then DataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect DataGridView1.CurrentCell.Selected = True End If End Sub
