优化GridView

Question

基本上，我需要帮助提高一个完整的gridviews页面的性能，以减少C＃的数量和移动尽可能多的GridView设置到ASP代码（而不是数据本身，这是在运行时绑定，需要留在C＃）。

我对GridView控件比较陌生，需要帮助将设置移动到GridView中，因为此代码所在的页面将有大约8或9个表格。

这里是我的ASP代码：

<asp:GridView runat="server" ID="tblBasicProcessingTime" 
    Caption="Basic Processing Stats" ShowHeader="False"> 
</asp:GridView> 

而我的C＃代码：

var longestTime = ReportData.OrderByDescending(x => x.TimeSpentProcessing).FirstOrDefault(); 
var averageTime = ReportData.Average(x => x.TimeSpentProcessing); 
var shortestTime = ReportData.OrderBy(x => x.TimeSpentProcessing).FirstOrDefault(); 

var table = new DataTable(); 

const string col1Name = "Header"; 
const string col2Name = "Data"; 

table.Columns.Add(col1Name); 
table.Columns.Add(col2Name); 

var row1 = table.NewRow(); 
row1[col1Name] = "Longest Processing Time"; 
row1[col2Name] = longestTime.TimeSpentProcessing; 
table.Rows.Add(row1); 

var row2 = table.NewRow(); 
row2[col1Name] = "Average Processing Time"; 
row2[col2Name] = averageTime; 
table.Rows.Add(row2); 

var row3 = table.NewRow(); 
row3[col1Name] = "Shortest Processing Time"; 
row3[col2Name] = shortestTime.TimeSpentProcessing; 
table.Rows.Add(row3); 

tblBasicProcessingTime.DataSource = table; 
tblBasicProcessingTime.DataBind(); 

在此先感谢。

这只是一个简单的演示gridview数据绑定。 然而，我的头文字是从资源文件加载，你可以自己设置，像串“AAA”，“BBB”，“CCC”

在后端，你的代码可能是这样的：

DataTable dt = SqlHelper.ExcuteDataSet("select * from InStoreHistory"); 
gvList.DataSource = dt; 
gvList.DataBind();
