Question

是否有一个简单的调用webService方法重新绑定asp.Net GridView控件并返回其呈现的html，以便我可以刷新页面上包含gridview的区域？

我可以使用jQuery.Load但是在服务器端如何获取特定控件的渲染块？

Answer 1

您可以使用Gridview.RenderControl（）方法。

 System.IO.StringWriter stringWrite = new System.IO.StringWriter();    
 System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);    
 GridView2.RenderControl(htmlWrite);

public override void VerifyRenderingInServerForm(Control control)
    {
       // Confirms that an HtmlForm control is rendered for the
       // specified ASP.NET server control at run time.
       // No code required here.
    }

你可以在网络方法中做这样的事情。

        GridView gv = new GridView();
        gv.AutoGenerateColumns = true;
        //Your Logic to fill dataset/datatable
        DataTable dt=new DataTable();
        dt.Columns.Add(new DataColumn("Index"));
        dt.Columns.Add(new DataColumn("Name"));
        for(int i=0;i<10;i++)
        {
            DataRow row=dt.NewRow();
            row["Index"]=i;
            row["Name"]="dummyData"+i.ToString();
            dt.Rows.Add(row);
        }
        //bind the gridview
        gv.DataSource = dt;
        gv.DataBind();
        //get the rendered HTML
        StringBuilder sb = new StringBuilder();
        StringWriter writer=new StringWriter(sb);
        HtmlTextWriter txt = new HtmlTextWriter(writer);
        gv.RenderControl(txt);
        return sb.ToString();

我可以通过webService调用获取gridview的渲染html吗？
