如何在自己编写的控件中添加一个已有的控件??

[zyycode]

using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;

namespace WebControlLibrary1
{

public class WebCustomControl1 : System.Web.UI.WebControls.WebControl
{
private Button button = new Button();
protected override void Render(HtmlTextWriter output)
{
button.Text="MyButton";
output.Write("<asp:Button id=button runat=server Text=Button></asp:Button>");
output.Write("test");
}
}
}


这么做好象不行...

在ascx文件里加看看

当然不行。

据个简单的例子：

TableCell tableCell = 你的控件.Cells[0];
private Button button = new Button();
button .ID="它的ID"
tableCell.Contorl.add(button)
这样才能作为服务器端的控件用，多参考一下资料，以前有个分页的DataGrid是个很好的例子

用容器
然后
容器.Controls.Add(button)

[saucer]

try

using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;

namespace WebControlLibrary1
{

public class WebCustomControl1 : System.Web.UI.WebControls.WebControl
{
private Button button = new Button();

protected override void CreateChildControls()
{
button.Text="MyButton";
button.ID = "button";
Controls.Add(button);
}

}
}


or



using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;

namespace WebControlLibrary1
{

public class WebCustomControl1 : System.Web.UI.WebControls.WebControl
{
private Button button = new Button();

protected override void Render(HtmlTextWriter output)
{
//not easy to handle events
button.Text="MyButton";
button.ID = "button";
button.RenderControl(output);
}
}
}

我一般是在.ascx文件中加的
