一个数据网格中的勾选复选框未在另一个数据网格中勾选 [英] Tick checkbox in one datagrid isn't being tick in another datagrid

问题描述

您好

我最近遇到了数据网格问题，尤其是复选框

我的问题是我有2个表单，都带有datagrid，并且都有需要勾选的复选框。当我勾选主表单中的一个复选框时，另一个复选框不会勾选。 

我一直在测试这段代码，但没有运气。

 Private Sub btnWVValidate_Click（sender as Object，e As EventArgs）处理btnWVValidate.Click 
 For i As Integer = 0 To GVWVorders.Rows.Count（ ） -  1步+1 
 Dim check As Boolean = DGVWVorders.Rows（i）.Cells（3）.Value 
 Dim row As DataGridViewRow = DGVWVorders.Rows（i）
如果check = True然后
 for j As Integer = 0 to frmCustomerOrderStatus.DGVOrderDetails.Rows.Count（） -  1 Step +1 
 Dim check2 As Boolean = frmCustomerOrderStatus.DGVOrderDetails.Rows（j）.Cells（1）。值
如果frmCustomerOrderStatus.DGVOrderDetails.Rows（j）.Cells（1）.Value = True则
否则
 frmCustomerOrderStatus.DGVOrderDetails.Rows（j）.Cells（1）.Value = False 
结束如果

我一直在努力改变编码：

 Private Sub btnWVValidate_Click（sender as Object，e As EventArgs）处理btnWVValidate.Click 
 For i As Integer = 0 To DGVWVorders.Rows.Count（） -  1 Step +1 
 Dim check As Boolean = DGVWVorders.Rows（i）.Cells（3）.Value 
 Dim row As DataGridViewRow = DGVWVorders.Rows（i）
如果check = True则
对于j As Integer = 0到frmCustomerOrderStatus.DGVOrderDetails.Rows.Count（） -  1步+1 
 Dim check2 As Boolean = frmCustomerOrderStatus.DGVOrderDetails.Rows（j）.Cells（1）.Value 
如果check2 = True则
 frmCustomerOrderStatus.DGVOrderDetails.Rows（j）.Cells（1）= T rue 
 Else 
 frmCustomerOrderStatus.DGVOrderDetails.Rows（j）.Cells（1）= False 
 End if 
 Next 
 End if 
 Next 
结束次级
结束等级

然而，两者都

 frmCustomerOrderStatus.DGVOrderDetails。行（j）。细胞（1）=真
 

和

 frmCustomerOrderStatus.DGVOrderDetails。行（j）.Cells（1）= False 

出现错误，其值不接受布尔值。

是否存在我的结构方式出错了吗？

解决方案

Vin，

错误信息是什么？

您是否遗漏了声明中的.value，即：

   frmCustomerOrderStatus.DGVOrderDetails.Rows（j）.Cells（1）。 value
= True

BTW，如果你试图在第二个dgv中设置相同的复选框，那么这可能会更容易吗？

          DataGridView1.Rows（0）.Cells（0）.Value = DataGridView2.Rows（0）.Cells（0）.Value

Hello

I've been having an issue with datagrid lately, especially with check boxes

My issue is that I have 2 forms, both with datagrid, and both have checkboxes that need to be ticked. When I tick one checkbox in my main form, the other checkbox won't tick. 

I've been testing with this code but have no luck.

 Private Sub btnWVValidate_Click(sender As Object, e As EventArgs) Handles btnWVValidate.Click
            For i As Integer = 0 To GVWVorders.Rows.Count() - 1 Step +1
            Dim check As Boolean = DGVWVorders.Rows(i).Cells(3).Value
            Dim row As DataGridViewRow = DGVWVorders.Rows(i)
            If check = True Then
                For j As Integer = 0 To frmCustomerOrderStatus.DGVOrderDetails.Rows.Count() - 1 Step +1
                    Dim check2 As Boolean = frmCustomerOrderStatus.DGVOrderDetails.Rows(j).Cells(1).Value
                    If frmCustomerOrderStatus.DGVOrderDetails.Rows(j).Cells(1).Value = True Then
                    Else
                        frmCustomerOrderStatus.DGVOrderDetails.Rows(j).Cells(1).Value = False
                    End If
                Next
            End If
        Next
    End Sub
End Class

Please help, Vincent

EDIT

I've been trying for a bit and changed the coding around:

Private Sub btnWVValidate_Click(sender As Object, e As EventArgs) Handles btnWVValidate.Click
        For i As Integer = 0 To DGVWVorders.Rows.Count() - 1 Step +1
            Dim check As Boolean = DGVWVorders.Rows(i).Cells(3).Value
            Dim row As DataGridViewRow = DGVWVorders.Rows(i)
            If check = True Then
                For j As Integer = 0 To frmCustomerOrderStatus.DGVOrderDetails.Rows.Count() - 1 Step +1
                    Dim check2 As Boolean = frmCustomerOrderStatus.DGVOrderDetails.Rows(j).Cells(1).Value
                    If check2 = True Then
                        frmCustomerOrderStatus.DGVOrderDetails.Rows(j).Cells(1) = True
                    Else
                        frmCustomerOrderStatus.DGVOrderDetails.Rows(j).Cells(1) = False
                    End If
                Next
            End If
        Next
    End Sub
End Class

However, both 

 frmCustomerOrderStatus.DGVOrderDetails.Rows(j).Cells(1) = True

and

 frmCustomerOrderStatus.DGVOrderDetails.Rows(j).Cells(1) = False

come up with errors with the values not accepting the boolean.

Is there an error with the way I've structured it?

解决方案

Vin,

What is the error message?

Did you leave out the .value from your statement ie:

   frmCustomerOrderStatus.DGVOrderDetails.Rows(j).Cells(1).value = True

BTW, if you are trying to set the checkboxes the same in the second dgv then maybe this will be easier?

        DataGridView1.Rows(0).Cells(0).Value = DataGridView2.Rows(0).Cells(0).Value
