Winform: Right-click at the beginning of the Datagridview column to bring up the hidden column menu

In Winform, right-click the displayed menu of the Datagridview. Many people have done this. See the following link.

However, when you have many columns or you are not familiar with your column names, it is a headache to check the columns to be displayed.

The following describes how to directly hide the current column.

First, add a dview and ContextMenuStrip to the FORM, and add a ToolStripMenuItem with the display name (hidden) to ContextMenuStrip.

The code is very simple. I added the variable TempColIndex to store the index of the current column, so I will not comment on it.

 

 Public Class Form1
Dim TempColIndex As Int16 =-2
Private Sub maid (ByVal sender As Object, ByVal e As System. Windows. Forms. Maid) Handles maid
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 hide ToolStripMenuItem_Click (ByVal sender As System. Object, ByVal e As System. EventArgs) Handles hide 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 maid (object sender, System. Windows. Forms. Maid e)
{
If (e. Button = Windows. Forms. MouseButtons. Right ){
If (e. RowIndex <0 ){
TempColIndex = e. ColumnIndex;

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

}
}

Private void hide ToolStripMenuItem_Click (System. Object sender, System. EventArgs e)
{
If (TempColIndex> = 0 ){
DataGridView1.Columns (TempColIndex). Visible = false;
}
}
}
