我有一个GridView控件,其中包含一个包含数据绑定的RadioButtonList的列。 RBL正确绑定到其DataTable,但未在GridView中显示。在标记中添加ListItem确实显示,并且Label控件正在显示 - 我只是将这两个作为测试。有没有人看到我失踪的东西?
TIA提供任何帮助。 麦克
标记:
<asp:TemplateField HeaderText="Preset Text" HeaderStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:RadioButtonList ID="rblPresetText" runat="server" DataValueField="pKey" DataTextField="Contents" GroupName="PresetText" RepeatDirection="Vertical"></asp:RadioButtonList>
</ItemTemplate>
</asp:TemplateField>
代码隐藏:
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
GlobalVar.LoadData(Session("UserPKey"))
Header1.ConnectionStr = GlobalVar.ConnectString
Header1.HDLawFirm = GlobalVar.LawFirmDir
If Page.IsPostBack = False Then
FillNotesDataSet()
BindNotesGrid()
BindPresetTextRadioButtonList()
End If
End Sub
Protected Sub BindPresetTextRadioButtonList()
Dim DAL As New DataAccessLayer
Dim dtPresetText As New DataTable
Dim rblPresetText As New RadioButtonList
dtPresetText = DAL.GetTextPickerTextForUser(Session("ClientKey"), Session("UserPKey"))
rblPresetText.DataSource = dtPresetText
rblPresetText.DataBind()
End Sub

您在TemplateField中声明RadioButtonList,但不是为每行检索该控件,而是创建一个新填充的RadioButtonList。由于新控件未包含在任何容器或GridView中,因此它不会显示在页面上。
您可以在GridView的RowDataBound
事件处理程序中获取TemplateField的RadioButtonList,并将数据绑定到该控件:
protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
RadioButtonList rblPresetText = e.Row.FindControl("rblPresetText") as RadioButtonList;
// Bind the data to the RadioButtonList
...
}
}
