如何在 Telerik C# 的 OnItemCreated 事件中获取列的值

Question

我有 Telerik 网格，我想在 OnItemCreated 事件中获取 GridBoundColumn 的值

这是我的代码

<telerik:RadGrid OnNeedDataSource="RGrid_NeedDataSource"  AutoGenerateColumns="false" OnItemCommand="RadGrid1_ItemCommand" OnItemDataBound="rad_RowDataBound" OnItemCreated="RadGrid1_ItemCreated" ID="radgrid" runat="server" AllowPaging="true" PagerStyle-AlwaysVisible="true" >
    <MasterTableView SkinID="SunSet">
     <Columns>
....
 <telerik:GridBoundColumn  FilterControlWidth="60" DataField="Status" HeaderText="Status" UniqueName="Status" HeaderStyle-Width="250px"></telerik:GridBoundColumn>
...
</AllColisgTags>

在我的 C# 代码中

 protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {

//Here I want to get the value of Status in string I have trid find controls 
e.Item.FindControl("Status");//Did not work
}
}

Answer 1

请尝试以下代码 sn-p。

ASPX

<telerik:GridBoundColumn  FilterControlWidth="60" DataField="Status" HeaderText="Status" UniqueName="Status" HeaderStyle-Width="250px"></telerik:GridBoundColumn>

ASPX.CS

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
 if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            string iss = item["Status"].Text; // Status is column Uniquename
        }
}

注意：我们无法在 ItemCreated 事件中获取/访问任何列/行的值。您必须使用 ItemDataBound 或 prerender 事件。

试试这个

<telerik:GridTemplateColumn  FilterControlWidth="60" DataField="Status" HeaderText="Status" UniqueName="Status" HeaderStyle-Width="250px">
 <asp:Label ID="Status" Text='<%# Bind("Status") %>' runat="server"></asp:Label>
</telerik:GridTemplateColumn>

C#

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
 if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            Label lbl = (Label)item["TemplateColumn"].FindControl("Status");
            string iss = lbl.Text;

        }
}
