动态绑定的记录窗口，我用      “任务设置”表      “记录窗口”列     动态设置记录窗口要显示的列及高度，当“记录窗口”列为空时就显示全部列，高度也为1，可总是出错，请老师帮助

Dim dt1 As Table = Tables(e.Form.name & "_table1")
Dim dr0 As DataRow = DataTables("任务设置").find("任务标题 = \'" & e.link.text & "\'")
dt1.DataSource = DataTables(e.link.name)   \'动态绑定表

\'记录窗口
Dim rgd As WinForm.RecordGrid = e.Form.Controls("RecordGrid1")   \'记录窗口
\'rgd.Table = dt1   ‘放在这里出错
If dr0.IsNull("记录窗口") = False Then
    Dim sz() As String = dr0("记录窗口").split("|")
    \'得到要显示的列
    Dim xt2 As String
    For i As Integer = 0 To sz.Length -1
        If i Mod 2 = 0 Then
            xt2 = xt2 & "|" & sz(i)
        End If
    Next
    xt2 = xt2.Trim("|")
    rgd.Columns = xt2   \'批量设置要显示的列
    \'遍历要显示的高度
    For i As Integer = 0 To sz.Length -1
        If i Mod 2 = 0 Then
            dt1.Cols(sz(i)).RecordRowHeight = Val(sz(i+1)) \'显示高度
        End If
    Next
End If
rgd.Table = dt1   ’放在这里也出错
rgd.Build() \'重新生成记录窗口

 谢谢！根据老师的指点，我重新改动了一下，OK

Dim dt1 As Table = Tables(e.Form.name & "_table1")
Dim dr0 As DataRow = DataTables("任务设置").find("任务标题 = \'" & e.link.text & "\'")
dt1.DataSource = DataTables(e.link.name)   \'动态绑定表

    rgd.Table = dt1
    Dim xt2 As String
    If dr0.IsNull("记录窗口") Then   \'如果不是空值,部分显示,如果为空,显示全部列
        For Each dc As DataCol In dt1.DataTable.DataCols
            xt2 = xt2 & "|" & dc.name
        Next
        xt2 = xt2.Trim("|")
        rgd.Columns = xt2   \'批量设置要显示的列
    Else
        Dim sz() As String = dr0("记录窗口").split("|")
        \'得到要显示的列
        For i As Integer = 0 To sz.Length -1
            If i Mod 2 = 0 Then
                xt2 = xt2 & "|" & sz(i)
            End If
        Next
        xt2 = xt2.Trim("|")
        rgd.Columns = xt2   \'批量设置要显示的列
        \'遍历要显示的高度
        For i As Integer = 0 To sz.Length -1
            If i Mod 2 = 0 Then
                dt1.Cols(sz(i)).RecordRowHeight = Val(sz(i+1)) \'显示高度
            End If
        Next
    End If
