结合从$ C $的LinqDataSource C-背后的GridView [英] Binding LinqDataSource from code-behind to Gridview

问题描述

我在.aspx页面上grdidview控制，我试图从code动态连接背后并绑定在GridView但不知何故，抛出了我一个错误...什么是错的这个code？任何帮助吗？

 的LinqDataSource LDS_POReport =新的LinqDataSource（）;
            LDS_POReport.ContextTypeName =DataContextDataContext;
            LDS_POReport.Selecting + =新的EventHandler＆LT; LinqDataSourceSelectEventArgs＆GT;（LinqDataSourcePO_Selecting）;
            this.gvReport.DataSource =LDS_POReport;
            //this.gvReport.DataBind（）;
 

更新：

后，我更新code到

  this.gvReport.DataSource = LDS_POReport;
 

它工作正常，但是当我尝试整理我得到这个错误：

GridView控件gvReport解雇事件排序
这是不处理的。

我补充这一点，但没有效果。

  LDS_POReport.AutoPage = TRUE;
 LDS_POReport.AutoSort = TRUE;
 

解决方案

我的猜测的，你的问题就在这里：

  this.gvReport.DataSource =LDS_POReport;
 

以上code线试图将一个字符串分配给需要某种数据源的一个属性。我假设你真的打算分配的LinqDataSource 对象本身：

  this.gvReport.DataSource = LDS_POReport;
 

i have a grdidview control on the .aspx page and i am trying to connect dynamically from code behind and bind the gridview but somehow it throwing me an error... what is wrong with this code? any help?

  LinqDataSource LDS_POReport = new LinqDataSource();
            LDS_POReport.ContextTypeName = "DataContextDataContext";
            LDS_POReport.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDataSourcePO_Selecting);
            this.gvReport.DataSource = "LDS_POReport";
            //this.gvReport.DataBind();

Update:

after i update the code to

 this.gvReport.DataSource = LDS_POReport;

it works fine but when i try to sort i get this error:

The GridView 'gvReport' fired event Sorting which wasn't handled.

i added this but no effect.

 LDS_POReport.AutoPage = true;
 LDS_POReport.AutoSort = true;

解决方案

I guess that your problem is here:

this.gvReport.DataSource = "LDS_POReport";

The above code line attempts to assign a string to a property that expects some sort of data source. I assume that you really intended to assign the LinqDataSource object itself:

this.gvReport.DataSource = LDS_POReport;
