Winform實現在Datagridview列首右鍵彈出隱藏列菜單

在Winform中右鍵彈出Datagridview顯示列菜單已經有很多人做了,參看下面連結.

但當你的有很多很多列或你對你的列名們不是太熟悉就有些麻煩了,把要顯示的列勾選出來是一件很頭疼的事.

下面提出直接隱藏當前列的辦法,以拋磚引玉.

首先在FORM中添加一個Datagridview,一個ContextMenuStrip,給ContextMenuStrip加一個顯示名為(隱藏)的ToolStripMenuItem

代碼很簡單,加了個變數TempColIndex儲存當前列的索引,我就不做注釋了.

 

Public Class Form1
Dim TempColIndex As Int16 = -2
Private Sub DataGridView1_CellMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.CellMouseDown
If e.Button = Windows.Forms.MouseButtons.Right Then
If e.RowIndex < 0 Then
                TempColIndex = e.ColumnIndex
                ContextMenuStrip1.Show(MousePosition.X, MousePosition.Y)

End If
End If

End Sub

Private Sub 隱藏ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles 隱藏ToolStripMenuItem.Click
If TempColIndex >= 0 Then
            DataGridView1.Columns(TempColIndex).Visible = False
End If
End Sub
End Class

 

public class Form1 
{ 
    Int16 TempColIndex = -1; 

private void DataGridView1_CellMouseDown(object sender, System.Windows.Forms.DataGridViewCellMouseEventArgs e) 
    { 
if (e.Button == Windows.Forms.MouseButtons.Right) { 
if (e.RowIndex < 0) { 
                TempColIndex = e.ColumnIndex; 

                ContextMenuStrip1.Show(MousePosition.X, MousePosition.Y); 
            } 

        } 
    } 

private void  隱藏ToolStripMenuItem_Click(System.Object sender, System.EventArgs e) 
    { 
if (TempColIndex >= 0) { 
            DataGridView1.Columns(TempColIndex).Visible = false; 
        } 
    } 
}
