VB.NET - 隐藏datagridview的左上角单元格 [英] VB.NET - Hide the top left corner cell of a datagridview

问题描述

我有一个3行2列的datagridview。我的行和列都有标题。

问题是我在datagridview的左上角有一个空单元格。我认为这是我的rowheaders的列标题或类似的东西。我没有成功隐藏这个细胞，这有可能吗？

谢谢

示例：

 隐藏此单元| colHead1 | colHead2 | 
 -------------------------------------- 
 firstname | x | y | 
姓氏| x1 | y1 | 
 society | x2 | y2 | 
  

编辑：
我试着设置属性 dtgv.TopLeftHeaderCell.Visible 为False，但它是ReadOnly。

解决方案

取消我的评论。您可以 完成此操作 - 手动。例如，在一个平淡/未修改的 DataGridView 中的 DataGridView.CellPainting 事件处理程序中，您可以像这样匹配背景：

 如果e.RowIndex< 0还有e.ColumnIndex< 0然后
使用笔刷作为新的SolidBrush（Me.dataGridView1.BackgroundColor）
 e.Graphics.FillRectangle（brush，e.CellBounds）
结束使用
 
 e。 Handled = True 
 End If

我想要显示表格的背景

如果你的意思是你想要设置 DataGridView 背景到Form的背景，这两个（C＃）答案用户

I have a datagridview with 3 rows and 2 columns. My rows and columns have headers.

The problem is that i have an empty cell on the top left corner of my datagridview. I think it is the column header of my rowheaders or something like that. I don't success to hide this cell, is it possible ?

Thank you

Example :

hide this cell  | colHead1| colHead2 |
--------------------------------------
firstname       | x       | y        |
lastname        | x1      | y1       |
society         | x2      | y2       |

EDIT : I tried to set the property dtgv.TopLeftHeaderCell.Visible to False, but it is ReadOnly.

解决方案

I rescind my comment. You can accomplish this - manually. For example, in your DataGridView.CellPainting event handler in a bland/unmodified DataGridView, you can match the background like so:

If e.RowIndex < 0 AndAlso e.ColumnIndex < 0 Then
    Using brush As New SolidBrush(Me.dataGridView1.BackgroundColor)
        e.Graphics.FillRectangle(brush, e.CellBounds)
    End Using

    e.Handled = True
End If

i would like to show the background of the form

If you meant you want to set the DataGridView background to the Form's background these two (C#) answers by users Deumber and letsdance demonstrate the general setup to crop the correct portion of the Form's image into the DataGridView. Using their methods (without calling SetCellsTransparent()) coupled with the following change to your DataGridView.CellPainting event handler should work:

If e.RowIndex < 0 AndAlso e.ColumnIndex < 0 Then
    e.Graphics.FillRectangle(Brushes.Transparent, e.CellBounds)  
    e.Handled = True
End If
