優化GridView

Question

基本上，我需要幫助提高一個完整的gridviews頁面的性能，以減少C＃的數量和移動儘可能多的GridView設置到ASP代碼（而不是數據本身，這是在運行時綁定，需要留在C＃）。

我對GridView控件比較陌生，需要幫助將設置移動到GridView中，因爲此代碼所在的頁面將有大約8或9個表格。

這裏是我的ASP代碼：

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

而我的C＃代碼：

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(); 

在此先感謝。

<asp:GridView

      </Columns> 
      <PagerStyle HorizontalAlign="Left" /> 
      <PagerSettings Position="TopAndBottom" Mode="Numeric" /> 
     </asp:GridView> 

這只是一個簡單的演示gridview數據綁定。 然而，我的頭文字是從資源文件加載，你可以自己設置，像串「AAA」，「BBB」，「CCC」

在後端，你的代碼可能是這樣的：

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