ASPX Page:
<asp:ListView ID="lvSubjects" runat="server" >
<LayoutTemplate>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
<asp:CheckBox ID="cbRegularSubjects" Text=<%# Eval("SubjectName") %> runat="server" />
</ItemTemplate>
<AlternatingItemTemplate>
<asp:CheckBox ID="cbRegularSubjects" Text=<%# Eval("SubjectName") %> runat="server" />
</AlternatingItemTemplate>
</asp:ListView>
代码隐藏:
For Each ctrl As Control In Page.Controls
If TypeOf ctrl Is CheckBox AndAlso CType(ctrl, CheckBox).Checked Then
'**Here I want to get the text of the check box and insert into the DB**
End If
Next
我哪里出错了??我没有收到任何错误...但是这段代码对我不起作用。
For i As Integer = 0 To lvSubjects.Items.Count - 1
Dim coll As ControlCollection = lvSubjects.Items(i).Controls
For Each c As Control In coll
If TypeOf c Is CheckBox Then
Dim box As CheckBox = CType(c, CheckBox)
If box.Checked Then
MsgBox(box.Text)
End If
End If
Next c
Next i
您只在Page.Controls中搜索,而您的复选框在页面控件层次结构中更深。
foreach (ListViewItem row in listView.Rows)
{
if (row.ItemType == ListViewItemType.DataItem)
{
CheckBox chk = row.FindControl("Checkboxid");
if (chk.Checked)
{
//Write code to store this checkbox value to database here
}
}
}
请使用正确的控件名称更改 VB 中的代码
