如何在gridview中的Template字段中应用排序 [英] How to apply sorting in Template field in gridview

问题描述

<asp:GridView ID="gridEdit" runat="server" AutoGenerateColumns="False" AllowPaging="true"AllowSorting="true" PageSize="5" OnPageIndexChanging="gridEdit_PageIndexChanging"OnRowDataBound="gridEdit_RowDataBound" Width="100%" CssClass="grid" OnSorting="gridEditSortOnSort">
 <Columns>
<asp:TemplateField SortExpression="DateViewedByAudience" ItemStyle-Width="20%">
<HeaderTemplate>
      <asp:Label ID="lblHeaderDateViewedByAudience" runat="server" Text=""></asp:Label>
</HeaderTemplate>
      <ItemTemplate>
                <asp:Label ID="lblDateViewedByAudience" runat="server"</asp:Label>
      </ItemTemplate>
</asp:TemplateField>

<PagerSettings FirstPageText="First" LastPageText="Last" Mode="NumericFirstLast"/>
</asp:GridView>

有人可以帮我在lblDateViewedByAudience字段中进行排序。

在数据绑定字段中它很容易但是通过模板字段我只是不能这样做。

排序选项不在网格中

提前谢谢

1. 使用模板字段手动输出GRIDVIEW [ ^ ]。

1. SORTING GRIDVIEW MANUALLY WITH TEMPLATEFIELDS[^].

<asp:TemplateField>
            <HeaderTemplate>
                <asp:LinkButton ID="LinkButtonEmpName" runat="server" Text="Employee Name" CommandName="Sort" CommandArgument="Employees">
                </asp:LinkButton>
            </HeaderTemplate>
            <ItemTemplate>
                <asp:Label ID="LabelEmployee" runat="server" Text='<%# Bind("Employees") %>'/>
            </ItemTemplate>
            <FooterTemplate>
                <asp:TextBox ID="TextBoxEmployee" runat="server"/>
            </FooterTemplate>
</asp:TemplateField >

2. 排序gridView通过适当的列，即TemplateField [ ^ ]

2. Sort gridView by proper column which is TemplateField[^]

<asp:TemplateField SortExpression="Status">
    <HeaderTemplate>
        <asp:LinkButton ID="lnkSort" runat="server" Text="Status" CommandName="Sort" CommandArgument="Status" />
    </HeaderTemplate>
</asp:TemplateField>

protected void grd_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName.Equals("Sort"))
    {
        FilterExpression = e.CommandArgument.ToString() + " LIKE '%" + txtCaseNumber.Text + "%'";
        BindGridView();
    }
}

3. 使用自定义模板字段排序Gridview [ ^ ]。

3. Gridview sorting with custom template fields[^].

<asp:TemplateField HeaderText="Category" SortExpression="Category">
   <ItemTemplate>A value</ItemTemplate>
</asp:TemplateField>

谢谢......

问题是排序不是因为您的标题模板在网格视图上触发，您使用标签。你必须使用 LinkBut​​ton修改它

Problem is sorting is not fired on the grid view because your header template, you are using a Label. you have to modified that using LinkButton

<asp:gridview id="gridEdit" runat="server" autogeneratecolumns="False" allowpaging="true" allowsorting="true" pagesize="5" onpageindexchanging="gridEdit_PageIndexChanging" onrowdatabound="gridEdit_RowDataBound" width="100%" cssclass="grid" onsorting="gridEditSortOnSort" xmlns:asp="#unknown">
 <columns>
<asp:templatefield sortexpression="DateViewedByAudience" itemstyle-width="20%">
<HeaderTemplate>
	<asp:linkbutton id="lblHeaderDateViewedByAudience" runat="server" text="" commandname="Sort" commandargument="DateViewedByAudience">      
</HeaderTemplate>
      <itemtemplate>
                <asp:label id="lblDateViewedByAudience" runat="server"></asp:label>
      </itemtemplate>
</asp:linkbutton></asp:templatefield>
 
<pagersettings firstpagetext="First" lastpagetext="Last" mode="NumericFirstLast" />
</columns></asp:gridview>
