我試圖通過優化分頁實現排序,但是當我嘗試排序時,沒有任何反應。排序標題的設計更改,就是這樣。Gridview排序不起作用
的GridView:
<div align="center">
<asp:ObjectDataSource ID="odsSupplier" runat="server" SelectMethod="GetSuppliers"
TypeName="Supplier" EnablePaging="True" MaximumRowsParameterName="PageSize" SelectCountMethod="GetRowsCount" StartRowIndexParameterName="StartRow" SortParameterName="sortBy">
</asp:ObjectDataSource>
<asp:GridView ID="supplierGridView" runat="server" AllowSorting="True"
CellPadding="4" DataSourceID="odsSupplier"
ForeColor="#333333" GridLines="None" AllowPaging="True" PageSize="15"
Width="300px">
<Columns>
<asp:ButtonField ButtonType="button" CommandName="Ed" HeaderText="Edit"
Text="Edit">
<ControlStyle Width="75px" />
<HeaderStyle HorizontalAlign="Center" Width="75px" />
<ItemStyle Width="75px" HorizontalAlign="Center" />
</asp:ButtonField>
<asp:ButtonField ButtonType="button" CommandName="Del" HeaderText="Delete"
Text="Delete">
<ControlStyle Width="75px" />
<HeaderStyle HorizontalAlign="Center" Width="75px" />
<ItemStyle Width="75px" HorizontalAlign="Center" />
</asp:ButtonField>
</Columns>
<EditRowStyle BackColor="#999999" />
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<PagerSettings Mode="NumericFirstLast" />
<PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
<RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
<SortedAscendingCellStyle BackColor="#E9E7E2" />
<SortedAscendingHeaderStyle BackColor="#506C8C" />
<SortedDescendingCellStyle BackColor="#FFFDF8" />
<SortedDescendingHeaderStyle BackColor="#6F8DAE" />
<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
</asp:GridView>
</div>
供應者類
public DataView GetSuppliers(int StartRow, int PageSize)
{
return GetData(StartRow, PageSize, "EquipmentSupplierID");
}
public DataView GetSuppliers(int StartRow, int PageSize, string sortBy)
{
return GetData(StartRow, PageSize, sortBy);
}
public DataView GetSuppliers(string sortBy)
{
return GetData(int.MaxValue, 0, sortBy);
}
private DataView GetData(int StartRow, int PageSize, string sortBy)
{
dbconn db = new dbconn();
return db.getSupplierData(StartRow, PageSize, sortBy).DefaultView;
}
public int GetRowsCount()
{
dbconn db = new dbconn();
return db.getSupplierCount();
}
dbconn類
public int getSupplierCount()
{
open();
setQuery("SELECT COUNT(*) AS Count FROM equipmentsupplier");
MySqlDataReader msdr = executeReader();
msdr.Read();
int count = int.Parse(msdr["Count"].ToString());
close();
return count;
}
public DataTable getSupplierData(int StartRow, int PageSize, string sortBy)
{
open();
setQuery("SELECT * from equipmentsupplier ORDER BY ?SORT LIMIT ?StartRow, ?Total;");
setParameter("StartRow", StartRow);
setParameter("Total", PageSize);
setParameter("SORT", sortBy);
DataTable dt = new DataTable();
dt.Load(executeReader());
return dt;
}
當我梳理它,但它只是沒有顯示上的查詢返回正確的數據我網格視圖。
您是否在GridView之外使用UpdatePanel? – 2013-02-24 10:35:48
nope,我沒有使用更新面板。當我點擊標題時,該列突出顯示,但gridview上顯示的數據未被排序 – user2103743 2013-03-25 02:26:27
