添加標題VB.net/asp.net gridview？

Question

我知道這個問題已經回答了，在C＃中我一直試圖轉換並讓它工作，但是沒有成功嗎？

如果你幫忙，我將不勝感激

這是來自那個問題的圖像，我想做類似的事情。

這里是ASP.NET GridView第二個標題行的鏈接， 以跨越主標題行

Dim d As Date = Date.Today
        d = d.AddDays(-1)
        Label1.Text = d

        'connects to datawarehouse
        saocmd1.Connection = conn1
        conn1.Open()

        Dim ds As New DataSet

        'selects sql query
        'saocmd1.CommandText = MYQUERY"
        saoda1.Fill(saods1, "salesasoftable")

        Dim row As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal)

        Dim left As TableCell = New TableHeaderCell()
        left.ColumnSpan = 3
        row.Cells.Add(left)

        Dim totals As TableCell = New TableHeaderCell()
        totals.ColumnSpan = gridview1.Columns.Count - 3
        totals.Text = "Totals"
        row.Cells.Add(totals)

我的錯誤

Line 57:        If t IsNot Nothing Then

答案

Dim row As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal)

'spanned cell that will span the columns I don't want to give the additional header 
Dim left As TableCell = New TableHeaderCell()
left.ColumnSpan = 6
row.Cells.Add(left)

'spanned cell that will span the columns i want to give the additional header
Dim totals As TableCell = New TableHeaderCell()
totals.ColumnSpan = myGridView.Columns.Count - 3
totals.Text = "Additional Header"
row.Cells.Add(totals)

'Add the new row to the gridview as the master header row
'A table is the only Control (index[0]) in a GridView
DirectCast(myGridView.Controls(0), Table).Rows.AddAt(0, row)

從您的問題來看，您似乎無法將c＃轉換為vb.net。 這里有2個可以提供幫助的在線轉換器。

或者有形軟件有一個可以轉換整個項目的轉換器，但請注意它不是免費的。

最簡單的方法是在RowCreated事件上處理此問題。 您將測試正在處理的RowType，如果它是標題，則您：

1. 清除有問題的行單元格。
2. 將第一個單元格的Rowspan調整為2（對於您的圖像：數量已發貨）。
3. 緊接着刪除行單元格（對於您的圖像：總銷售額）。
4. 創建一個新表，使其看起來像您想要的那樣，如圖所示。
5. 將新表插入所需的行單元格。
