Hide a row in DataGridView
提问by user1532468
I am a new user to vb.net and need to hide a row when a user right clicks on a contextmenu and selects hide. I have googled this but have yet to find a way to do it.
我是 vb.net 的新用户，当用户右键单击上下文菜单并选择隐藏时，需要隐藏一行。我已经用谷歌搜索了这个，但还没有找到一种方法来做到这一点。
At the moment, when a user clicks on an entry in the grid, the value is entered into a text box which is fine. What I need to do is hide the entry the user right clicked on and hide the selection. As I am new I am finding it hard going to code this as I have just finished my first course which entailed the basics. Any help would be appreciated or if you need anymore code, then please ask.
目前，当用户单击网格中的条目时，该值会输入到文本框中，这很好。我需要做的是隐藏用户右键单击的条目并隐藏选择。由于我是新手，我发现很难编写代码，因为我刚刚完成了涉及基础知识的第一门课程。任何帮助将不胜感激，或者如果您需要更多代码，请询问。
Dim value As Object = UserDataGridView.Rows(e.RowIndex).Cells(0).Value
txtCustomerActive.Text = CType(value, String)
Private Sub HideToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles pnlContextMenuStrip1.ItemClicked
'Get the text of the item that was clicked on.
'Dim text As String = txtCustomerActive.Text
Try
'txtCustomerActive.Visible = False
pnlContextMenuStrip1.Visible = False
MessageBox.Show(txtCustomerActive.Text)
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub

You could use Rows.Item()to hide specific DataGridViewRow, like:
您可以使用Rows.Item()隐藏特定的DataGridViewRow，例如：
If (UserDataGridView.Rows.Count > 0) Then
For Each row As DataGridViewRow In UserDataGridView.SelectedRows
UserDataGridView.Rows.Item(row.Index).Visible = False
Next
End If
I am assuming you are using FullRowSelecthere.
我假设你在FullRowSelect这里使用。
If you are not using FullRowSelectyou could have this alternative code which could catch both Cellbeing Selected or Rowbeing Selected:
如果您不使用，FullRowSelect您可以使用此替代代码，它可以同时捕获Cell被选中或被Row选中：
If (UserDataGridView.SelectedRows.Count > 0) Then
For Each row As DataGridViewRow In UserDataGridView.SelectedRows
UserDataGridView.Rows.Item(row.Index).Visible = False
Next
ElseIf (UserDataGridView.SelectedCells.Count > 0) Then
For Each cell As DataGridViewTextBoxCell In UserDataGridView.SelectedCells
UserDataGridView.Rows.Item(cell.RowIndex).Visible = False
Next
End If
To Unhideeverything let's say from a Button Clickyou could have this:
对于Unhide一切，让我们说Button Click你可以拥有这个：
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
For Each row As DataGridViewRow In UserDataGridView.Rows
If (row.Visible = False) Then
UserDataGridView.Rows.Item(row.Index).Visible = True
End If
Next
End Sub

As far as I know, you can not make a server-side handler for right mouse click (as you did for HideToolStripMenuItem_Click, which works as part of .NET postback mechanism).
据我所知，您不能为鼠标右键单击创建服务器端处理程序（就像您为 HideToolStripMenuItem_Click 所做的那样，它是 .NET 回发机制的一部分）。
However, I believe that such feature could be done with some client-side javascript progamming.
但是，我相信可以通过一些客户端 javascript 编程来完成这样的功能。
Hope this helps!
希望这可以帮助！
