Question

首先，我创建了一个动态表，并添加了一些文本框。

        Dim tblRows As Integer = nos
        Dim tblCols As Integer = 2
        ''# Create a Table and set its properties 
        Dim tbl As Table = New Table()
        ''# Add the table to the placeholder control
        PlaceHolder1.Controls.Add(tbl)
        ''# Now iterate through the table and add your controls 
        For i As Integer = 0 To tblRows - 1
            Dim tr As TableRow = New TableRow()
            For j As Integer = 0 To tblCols - 1
                Dim tc As TableCell = New TableCell()
                Dim lbl As Label = New Label()
                lbl.Text = "Student Name"

                If j = 0 Then

                    tc.Controls.Add(lbl)
                    ''# Add the TableCell to the TableRow
                    tr.Cells.Add(tc)

                Else

                    Dim txtBox As TextBox = New TextBox()
                    ''#txtBox.AutoPostBack = True
                    txtBox.ID = "aa" + i.ToString()
                    ''#txtBox.ID = "TextBoxID" + (i + 1).ToString()
                    ''#txtBox(i) = New TextBox
                    ''# Add the control to the TableCell
                    tc.Controls.Add(txtBox)
                    ''# Add the TableCell to the TableRow
                    tr.Cells.Add(tc)

                End If

            Next j
            ''# Add the TableRow to the Table
            tbl.Rows.Add(tr)
        Next i
        Dim btn As Button = New Button()
        btn.Text = "SUBMIT"
        PlaceHolder1.Controls.Add(btn)

现在点击按钮我需要检索在各种文本框中输入的值并将其插入数据库。任何人都可以帮助我吗？

尝试查看此页面：Insert TextBoxes into a Repeater dynamically and retrieve their value

很快，您可以在Page_Load方法上动态添加控件，并在Button1_Click方法中获取值。要按ID查找控件，可以使用FindControl方法。

检索动态控件的值
