How do i create a checkall/uncheckall checkboxes button for my datagridview that has a checkbox column

推荐答案

如果确实存在单独的解决方案1的简单替代方法表单上的按钮而不是列标题...



假设按钮名为ButtonSelect，其中带有复选框的列名为CheckBoxColumn。



将按钮的文本初始化为全选，例如

A simple alternative to Solution 1 if there is indeed a separate button on your form rather than the column header ...

Assume the button is named "ButtonSelect" and the column with the checkbox in it is named "CheckBoxColumn".

Have the text of the button initialised to "Select All" e.g.

ButtonSelect.Text = "Select All"

然后添加以下代码

Private Sub ButtonSelect_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonSelect.Click

    Dim newValue As Boolean
    Dim newText As String

    If ButtonSelect.Text = "Select All" Then
        newText = "Unselect All"
        newValue = True
    Else
        newText = "Select All"
        newValue = False
    End If

    For Each dr As DataGridViewRow In DataGridView1.Rows
        dr.Cells("CheckBoxColumn").Value = newValue
        ButtonSelect.Text = newText
    Next
End Sub

如果发生这种情况，请道歉在解决方案1的视频链接中 - 我只是无法让自己观看整个事情。

Apologies if this is what happens in the video link from solution 1 - I just couldn't bring myself to watch the whole thing.
