我可以通过webService调用获取gridview的渲染html吗？

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？

谢谢

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web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();
