你可以使用一個隱藏字段來存儲ID:
<ItemTemplate>
<asp:HiddenField
runat="server"
ID="ID"
Value='<%# Eval("ID") %>'
/>
<asp:LinkButton
runat="server"
OnClick="LabelClick"
Text="click me"
/>
</ItemTemplate>
然後:
protected void LabelClick(object sender, EventArgs e)
{
var hiddenField = (HiddenField)((Control)sender).FindControl("ID");
var id = hiddenField.Value;
// Do something with the id
}
UPDATE:
全部工作示例:
<%@ Page Language="C#" %>
<script type="text/c#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
grid.DataSource = Enumerable.Range(1, 10).Select(x => new
{
ID = x
});
grid.DataBind();
}
}
protected void LabelClick(object sender, EventArgs e)
{
var hiddenField = (HiddenField)((Control)sender).FindControl("ID");
result.Text = string.Format("selected id: {0}", hiddenField.Value);
}
</script>

我得到這個錯誤「對象引用。 – jpavlov
來自此代碼: – jpavlov
第29行://使用SelectedRow屬性獲取當前選定的行。 第30行:GridViewRow row = gv2.SelectedRow; 第31行:string controlId =((LinkButton)row.FindControl(「ID」))。 第32行:lblshow.Text = controlId; – jpavlov
