Question

Noobie，问题，我不记得了！

我创建了一个可视化的webpart，它创建了一个用户控件，我在htnml视图中添加了一个转发器，现在我需要将它绑定到数据，但是我似乎无法在代码隐藏中找到转发器控件。

<table id="engagementletterReport" class="display" border="0">
     <thead>
         <tr>
             <th>JobCode</th>
             <th>JobName</th>
          </tr>
     </thead>
     <tbody>
         <asp:Repeater runat="server" ID="repeater">
             <ItemTemplate>
                 <tr>
                     <td>
                         <%# DataBinder.Eval(Container.DataItem, "JobCode") %>
                     </td>
                     <td>
                         <%# DataBinder.Eval(Container.DataItem, "JobName") %>
                     </td>
                 </tr>
             </ItemTemplate>
         </asp:Repeater>
     </tbody>
 </table>

我的网站

public class EngagementLetterWebPart : WebPart
    {
        // Visual Studio might automatically update this path when you change the Visual Web Part project item.
        private const string _ascxPath = @"~/_CONTROLTEMPLATES/15/xx.SP.xx.WebParts.WebParts/EngagementLetterWebPart/EngagementLetterWebPartUserControl.ascx";

        protected override void CreateChildControls()
        {
            Control control = Page.LoadControl(_ascxPath);
            Controls.Add(control);
        }

        protected override void OnLoad(EventArgs e)
        {
            BindData();
        }

        private void BindData()
        {
            //here, how??
            repeater.DataSource = JobContext.GetEngagementLetterReport(SPContext.Current.Site, true, 500, 1);
            repeater.DataBind();
        }
    }

您可以使用以下步骤绑定转发器

1.Declare一个公共变量

Control innerControl;

2.更改createchildcontrols函数，如下所示

protected override void CreateChildControls()
{
        innerControl = Page.LoadControl(_ascxPath);
        Controls.Add(innerControl);
}

3.更改BindData功能如下

private void BindData()
{
    if (innerControl != null)
    {
        //here, how??
        Repeater repeater = innerControl.FindControl("repeater") as Repeater;
        if (repeater != null)
        {
            repeater.DataSource = JobContext.GetEngagementLetterReport(SPContext.Current.Site, true, 500, 1);
            repeater.DataBind();
        }
    }
}

如何在webpart内的usercontrol中引用转发器
