Question

我需要在Gridview中添加Sub-Total和Total。在为子总计和总行添加代码之后，在网格的最终数据行上，＆＃34;编辑＆＃34;按钮没有长期发生它的事件。其余的网格编辑事件都会触发。我有几个不同的＆＃34;子部分和＃34;

到目前为止我发现了什么：

Sub-Total行的数量与不触发Edit事件的行数相同。（IE如果有2个子总计行，那么最后两个编辑按钮不再触发事件，仅导致回发删除小计总行。如果有3个则编辑不起作用，等等等））< / p>

如果没有Sub-Total行，Edit事件将按预期工作。

以下是我用来构建网格和Sub-Total / Total行的代码：

Row_DataBound：

Protected Sub gvFTEMedProc_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvFTEMedProc.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
        If DataBinder.Eval(e.Row.DataItem, "F_Med_Proced") <> "FTE Health Room Visit" Then
            If medicationCount <= 9 Then
                medicationCount += 1
                medicationProcedureType = "Medication"
            Else
                medicationCount += 1
                medicationProcedureType = "Procedures"
            End If
            Dim dblMedProcCount As Double = Convert.ToDouble(DataBinder.Eval(e.Row.DataItem, "F_Med_Proced_Num"))
            dblMedProcTotal += dblMedProcCount
            grandTotalMedProc += dblMedProcCount
        End If
    End If
    If e.Row.RowType = DataControlRowType.Footer Then
        e.Row.Cells(0).ColumnSpan = 2
        e.Row.Cells(0).Text = "Total (minus Health Room Visits):"
        e.Row.Cells(1).ColumnSpan = 2
        e.Row.Cells(1).Text = grandTotalMedProc.ToString("n0")
        e.Row.Cells(0).HorizontalAlign = HorizontalAlign.Right
        e.Row.Cells(1).HorizontalAlign = HorizontalAlign.Center
        e.Row.Cells(2).Visible = False
        e.Row.Cells(3).Visible = False
        e.Row.Font.Bold = True
        medicationProcedureType = String.Empty
        medicationCount = 0
    End If
End Sub

Row_Created：

Protected Sub gvFTEMedProc_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvFTEMedProc.RowCreated
    Dim IsSubTotalRowNeeded As Boolean = False

    If (medicationProcedureType <> String.Empty) AndAlso (DataBinder.Eval(e.Row.DataItem, "F_Med_Proced") IsNot Nothing) Then
        If medicationCount = 9 Then 'DataBinder.Eval(e.Row.DataItem, "School_Type").ToString() Then
            IsSubTotalRowNeeded = True
        End If
    End If

    If (medicationProcedureType <> String.Empty) AndAlso (DataBinder.Eval(e.Row.DataItem, "F_Med_Proced") Is Nothing) Then
        IsSubTotalRowNeeded = True
        intSubTotalIndex = 0
    End If
    If medicationProcedureType = "Procedures" Then
        Dim rowIndex = e.Row.RowIndex
    End If
    'The Issue is happening when I add this IF Statement.
    If IsSubTotalRowNeeded Then
        Dim gvtest As GridView = DirectCast(sender, GridView)

        'Create a Row
        Dim SubTotalRow As New GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Insert)

        'Adding Total Cell
        Dim HeaderCell As New TableCell()
        HeaderCell.Text = medicationProcedureType + " Sub Total:"
        HeaderCell.ColumnSpan = 2
        HeaderCell.HorizontalAlign = HorizontalAlign.Right
        HeaderCell.CssClass = "SubTotalRowStyle"
        SubTotalRow.Cells.Add(HeaderCell)

        'Adding Medication Column
        HeaderCell = New TableCell()
        HeaderCell.Text = String.Format("{0:N0}", dblMedProcTotal)
        HeaderCell.ColumnSpan = 2
        HeaderCell.HorizontalAlign = HorizontalAlign.Center
        HeaderCell.CssClass = "SubTotalRowStyle"
        SubTotalRow.Cells.Add(HeaderCell)

        'Adding the Row at the RowIndex position in the Grid
        gvtest.Controls(0).Controls.AddAt(e.Row.RowIndex + intSubTotalIndex, SubTotalRow)
        intSubTotalIndex += 1

        dblMedProcTotal = 0
    End If
End Sub

解决方案是将数据绑定添加到Page_Load中。（但是，在我的情况下，每个page_load都需要“if not page.ispostback（）”）

在我的情况下，我只是在从下拉菜单中选择时绑定数据。因此，当在回发上加载页面时，它不会重新绑定网格的Edit列（奇怪的是，只有网格的最后1-3行不会绑定，前10-12行将正常绑定）

在我的Change Event函数中，我处理了选择是否有效，如果进行了有效选择，则调用数据绑定函数。通过将更改事件功能添加到Page_Load，问题得以解决。现在，编辑按钮和网格在每个page_load上都可以正常运行，回传与否。

GridView编辑的最后一行失败
