推荐答案

add LinkBut​​ton 与 RowCommand 如下所示

add LinkButton with RowCommand like below

<asp:gridview autogeneratecolumns="false" runat="server" id="grdCustomPagging" onrowcommand="grdCustomPagging_RowCommand" >
   <columns>
     <asp:linkbutton runat="server" id="lnkView" commandargument='<%#Eval("DealId") %>'>
         CommandName="VIEW">View Deal</asp:linkbutton>
 </columns>
</asp:gridview>

in RowCommand 事件你可以加载下面的图形

in RowCommand event you can load the graph like below

protected void grdCustomPagging_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "VIEW")
    {
        LinkButton lnkView = (LinkButton)e.CommandSource;
        string dealId = lnkView.CommandArgument;
        // do something with CommandArgument value like loading graph 
    }
}

嗨Subhash，我建议你学习基础知识在ASP.NET中使用GridView控件。以下链接可能会对您有所帮助：

在ASP.NET Gridview中插入，更新，删除，作为SQL Server的DataSource，MS Access（mdb / accdb），XML和Framework为2.0 / 3.0 / 3.5 / 4.0（VS 2005/2008/2010） [ ^ ]

Hi Subhash, I would suggest you to learn basics of working with GridView control in ASP.NET. The following links might be helpful:

GridView all in one[^]

Insert, Update, Delete in ASP.NET Gridview, DataSource as SQL Server, MS Access (mdb/accdb), XML and Framework as 2.0 / 3.0 / 3.5 / 4.0 (VS 2005/2008/2010)[^]

有不同的方法可以做到这一点。首先，您可以使用 System.Drawing 动态生成某个位图中的图形。您可以将结果保存到文件中，或者在某个带有适当标题的ASP.NET页面中生成苍蝇的内容（例如image / png）。

另一种方法是生成基于HTML5 Canvas显示图形的Javascript： http：// en。 wikipedia.org/wiki/HTML5_canvas [ ^ ]。



您将能够找到几个可用的用于生成Canvas图形和不同类型的动画和交互行为的框架。请看我过去的回答：如何制作一个asp.net中的绘图区域 [ ^ ]。

There are different ways to do it. First, you can generate the graph in some bitmap on the fly, using System.Drawing. You can save result in a file or generate just the content of the fly in some ASP.NET page with appropriate header (such as "image/png").

Another approach could be generating Javascript showing graphics based on HTML5 Canvas: http://en.wikipedia.org/wiki/HTML5_canvas[^].

You will be able to find several available frameworks for generation of Canvas graphics and different kinds of animation and interactive behavior. Please see my past answer: how to make a drawing area in asp.net[^].
