我想通过单击列的标题对我的 GridView 进行排序。到目前为止,我声明了一个 SPDataSource
<SharePoint:SPDataSource
runat="server"
ID="SPdsInventarGrid"
DataSourceMode="List"
UseInternalName="true"
Scope="Recursive"
SelectCommand="<View><Query><Where><Or><Neq><FieldRef Name='EBS_x002e_CN_x002e_Inventar_x00210' /><Value Type='Text'>Open</Value></Neq><IsNull><FieldRef Name='EBS_x002e_CN_x002e_Inventar_x0028' /></IsNull></Or></Where></Query><ViewFields><FieldRef Name='Title'/><FieldRef Name='ID'/><FieldRef Name='EBS_x002e_CN_x002e_Inventar_x0028'/><FieldRef Name='EBS_x002e_CN_x002e_Inventar_x00210'/><FieldRef </ViewFields></View>">
<SelectParameters>
<asp:Parameter Name="ListName" DefaultValue="Inventar" />
</SelectParameters>
</SharePoint:SPDataSource>
然后我根据数据源创建了我的网格
<asp:GridView Visible="true" Width="100%"
ID="gvInventar"
AutoGenerateColumns="false" runat="server" CellPadding="2" AllowPaging="false" AllowSorting="true" OnSorted="gvInventar_Sorted" OnSorting="gvInventar_Sorting" GridLines="None" DataSourceID="SPdsInventarGrid" OnRowCommand="gvInventar_RowCommand">
<Columns>
<asp:CommandField ButtonType="Image" ShowEditButton="true" EditImageUrl="/_layouts/images/edit.gif" UpdateImageUrl="/_layouts/images/save.gif" CancelImageUrl="/_layouts/images/delete.gif" />
<asp:TemplateField HeaderText="ID">
<ItemTemplate>
<asp:Label Text='<%# Bind("ID") %>' runat="server" ID="lblIdProduct"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Title" >
<ItemTemplate>
<asp:Label Text='<%# Bind("Title") %>' runat="server" ID="lblTitleProduct" ></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Product" SortExpression="Product">
<ItemTemplate>
<asp:Label Text='<%# Bind("EBS_x002e_CN_x002e_Inventar_x0028") %>' runat="server" ID="lblProduct" "></asp:Label>
</ItemTemplate>
</Columns>
</asp:GridView>
现在,我有这个函数,我想将当前查询作为字符串获取并在之前添加<OrderBy>
(我的字段),<Query>
但是我收到一个错误,说 DataSource 已经被声明(这是真的,因为我想在 asp 中声明)
protected void gvInventar_Sorting(object sender, GridViewSortEventArgs e)
{
SPQuery q = new SPQuery();
q.Query = SPdsInventarGrid.SelectCommand;
switch (e.SortExpression)
{
case "Product":
if (e.SortDirection == SortDirection.Ascending)
{
gvInventar.DataSource = q.Query;
gvInventar.DataBind();
}
else
{
}
break;
}
}
即使它不以这种方式工作,我也不认为修改 Query 是解决方案。谁能帮我解决这个问题?
