Question

基本上我需要帮助提高满足gridviews的页面的性能，以减少C＃的数量，并将尽可能多的GridView设置移动到ASP代码中（而不是数据本身，在运行时绑定并需要保留在C＃中）。

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包含大约8或9个表。

这是我的ASP代码：

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

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();

提前致谢。

                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderStyle-Width="10%" HeaderText="<%$ Resources: CommonResources, lbl_InstoreHistPartNo.Text %>" SortExpression="PartCode">

                            <asp:Label ID="lbl_InstoreHistPartName" runat="server" Text='<%#Eval("PartName")%>'/>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderStyle-Width="10%" HeaderText="<%$ Resources: CommonResources, lbl_InstoreHistInQuality.Text %>" SortExpression="Quality">

                    <ItemTemplate>
                            <asp:Label ID="lbl_InstoreHistInQuality" runat="server" Text='<%#Eval("Quality")%>'/>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderStyle-Width="10%" HeaderText="<%$ Resources: CommonResources, lbl_InstoreHistInUsercode.Text %>" SortExpression="UserCode">
                    <ItemTemplate>
                        <asp:Label ID="lbl_InstoreHistInUsercode" runat="server" Text='<%#Eval("UserCode")%>'/>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderStyle-Width="15%" HeaderText="<%$ Resources: CommonResources, lbl_InstoreHistInTime.Text %>" SortExpression="InStoreDate">
                </asp:TemplateField>
            </Columns>
            <PagerStyle HorizontalAlign="Left"   />
            <PagerSettings Position="TopAndBottom" Mode="Numeric" />
        </asp:GridView>

这只是gridview数据绑定的简单演示。但是，我的标题文本是从资源文件加载的，你可以自己设置，比如字符串“aaa”，“bbb”，“ccc”

在后端，您的代码可能是这样的：

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