datagridview复选框计数器 [英] datagridview checkbox counter

问题描述

大家好！

我正在尝试计算datagridview中选中的复选框的数量，但计数器的返回值为0.
谁能给我一个线索，为什么会这样?

Hi all!

I''m trying to count the number of the checked checkboxes in the datagridview, but the counter return value is 0.
Can anyone give me a clue why that is so?

Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick

        Dim pcount As Integer = 0
        For Each row As DataGridViewRow In DataGridView1.Rows
            If row.Cells(0).Value = True Then
                pcount += 1
            End If
        Next
        Label2.Text = pcount
    End Sub

谢谢！

Thanks!

推荐答案

在执行事件之前，必须以表格加载的方式再次将网格重新绑定到数据集！使用DEBUGGER，看看是否是这种情况.

You must be re-binding the grid to dataset again in form load, before the event is executed! Use DEBUGGER and see if that''s the case.
