c1:C1DataGrid 的标题上的筛选问题

登录

c1:C1DataGrid 的标题上的筛选，我试了试，只有纯数字的能筛选成功，列里有字母的就没办法筛选了？是我哪设置的问题吗？

前台代码
<c1:C1DataGrid x:Name="MyGrid" AutoGenerateColumns="False"
                        HorizontalAlignment="Stretch"
                        VerticalAlignment="Stretch"
                        CanUserFreezeColumns="None"
                        IsReadOnly="True"
                        RowHeight="25"
                        AlternatingRowBackground="White"
                        ScrollMode="Deferred"
                        GridLinesVisibility="All"
                        SelectionMode="MultiRange"
                        ColumnHeaderClickAction="Select"

                        >
            <c1:C1RowIndexHeaderBehavior.RowIndexHeaderBehavior>
                  <c1:C1RowIndexHeaderBehavior InitialIndex="1"/>
            </c1:C1RowIndexHeaderBehavior.RowIndexHeaderBehavior>
            <c1:C1DataGrid.Columns>
                  <c1

ataGridTextColumn Binding="{Binding Path=ID}" Width="60" FilterMemberPath="ID" SortMemberPath="ID" Header="ID" />
<c1

ataGridTextColumn Binding="{Binding OrderNo}" Width="105" FilterMemberPath="订单号" SortMemberPath="订单号" Header="订单号" />
<c1

<c1

<c1

<c1

ataGridTextColumn Binding="{Binding Frequency_Name}" Width="77" FilterMemberPath="检验过程" SortMemberPath="检验过程" Header="检验过程" />
<c1

ataGridTextColumn Binding="{Binding SemiProduct_SerNo}" Width="90" FilterMemberPath="订单唯一码" SortMemberPath="订单唯一码" Header="订单唯一码" />
<c1

ataGridTextColumn Binding="{Binding prdPerson}" Width="70" FilterMemberPath="工号" SortMemberPath="工号" Header="工号" />
<c1

ataGridTextColumn Binding="{Binding PersonName}" Width="100" FilterMemberPath="检验人" SortMemberPath="检验人" Header="检验人" />
<c1

ataGridTextColumn Binding="{Binding Note}" Width="100"  FilterMemberPath="备注" SortMemberPath="备注" Header="备注"  />
                  <c1:DataGridTextColumn Binding="{Binding Recorddate}" Width="100"  FilterMemberPath="检验时间" SortMemberPath="检验时间" Header="检验时间"  />
                  <c1:DataGridTextColumn Binding="{Binding ProcessName}" Width="100"  FilterMemberPath="工序" SortMemberPath="工序" Header="工序"  />
                  <c1:DataGridTextColumn Binding="{Binding ObjectID}" Width="100"  FilterMemberPath="料号" SortMemberPath="料号" Header="料号"  />
            </c1:C1DataGrid.Columns>
         </c1:C1DataGrid>

后台代码
TestDal dal = new TestDal();
         DataTable dt = dal.GetCheck_RecordsetMain_Pad(tb_Serno.Text, tb_PersonID.Text,(DateTime) StartDate.DateTime, (DateTime)EndDate.DateTime);
         MyGrid.ItemsSource = dt.DefaultView;

c1:C1DataGrid 标题点击能排序，是哪个属性设置的，例子上，都能排序，但是好像又没有设置。
比如下面这个例子

<c1:C1DataGrid x:Name="grid" Grid.Row="1"
                        AutoGeneratingColumn="grid_AutoGeneratingColumn"
                        CanUserAddRows="False"
                        RowHeight="30"
                        IsReadOnly="true">
         <c1:C1FullTextSearchBehavior.FullTextSearchBehavior>
            <c1:C1FullTextSearchBehavior/>
         </c1:C1FullTextSearchBehavior.FullTextSearchBehavior>
      </c1:C1DataGrid>

CanUserSort ，设置成true了，但是还不能排序，还少什么吗
<c1:C1DataGrid x:Name="MyGrid" AutoGenerateColumns="False"
                        HorizontalAlignment="Stretch"
                        VerticalAlignment="Stretch"
                        CanUserFreezeColumns="None"
                        IsReadOnly="True"
                        RowHeight="25"
                        AlternatingRowBackground="White"
                        ScrollMode="Deferred"
                        GridLinesVisibility="All"
                        SelectionMode="MultiRange"
                        ColumnHeaderClickAction="Select"
                        CanUserSort="True"
                        >
            <c1:C1DataGrid.TopRows>
                  <c1

ataGridFilterRow />
            </c1:C1DataGrid.TopRows>
