老师，您好！我将甘特图的时间单位从日改为上、中、下旬后，在编写DrawCell事件代码时，运行不对，烦请诊断一下，谢谢！
If DrawGannt Then
Dim r As Row = Tables(_Sys_lsb2+"_Table1").Rows(e.Row.Index,True)
Dim t2 As Table = Tables(_Sys_lsb2+"_Table2")
Dim xt As String = r("阶段码")
Dim dt1 As Date = r("计划开始")
Dim dt2 As Date = r("计划完成")
Dim str1 As String '开始列名
Dim ks As Integer '开始偏移量
ks=dt1.Day
If dt1.Day <=10 Then
str1 = "上旬"
ks=dt1.Day
ElseIf dt1.Day <=20 Then
str1 = "中旬"
ks=(dt1.Day - 10)
ElseIf dt1.Day >20 Then
str1 = "下旬"
ks=(dt1.Day - 20)
End If
str1=dt1.Year & "年" & dt1.Month & "月_" & str1
Dim ids As Integer= t2.cols(str1).Index
Dim str2 As String '完成列名
Dim ke As Integer '完成偏移量
ke=dt2.Day
If dt2.Day <=10 Then
str2 = "上旬"
ke=dt2.Day
ElseIf dt2.Day <=20 Then
str2 = "中旬"
ke=(dt2.Day - 10)
ElseIf dt2.Day >20 Then
str2 = "下旬"
ke=(dt2.Day - 20)
End If
str2=dt2.Year & "年" & dt2.Month & "月_" & str2
Dim ide As Integer= t2.cols(str2).Index
'********************确定画笔颜色和线条宽度
Dim colr As Brush '画笔颜色
Dim kw As Integer = 16 '线条宽度
If r.IsGroup '如果是分组行
If r.Level = 0 Then
colr = Brushes.Red
ElseIf r.level = 1 Then
colr = Brushes.DarkOliveGreen
ElseIf r.level = 2 Then
colr = Brushes.Sienna
End If
Else
If xt.length=4 Then
colr = Brushes.DarkOrchid
Else
colr = Brushes.YellowGreen
kw = 18
End If
End If
'*****************画甘特图
For Each dc As DataCol In DataTables(_Sys_lsb2+"_Table2").DataCols
Dim idx As Integer=t2.cols(dc.Name).Index
If idx>=ids AndAlso idx<=ide Then
e.StartDraw()
e.Graphics.FillRectangle(colr,e.x ,e.y + 8, e.Width, e.Height - kw)
e.EndDraw()
End If
Next
End If
涂红部分好像不起作业，画出来全是从头到尾的一条线，与起止时间没关联。
