我如何可以动态地改变我的WPF GridView中列的顺序？ [英] How can I dynamically change the order of my GridView columns in WPF?

问题描述

我有两个单选按钮。 如果我点击第一个单选按钮我想列的顺序是：

• ASSETNAME
• 资产
• 组
• 类型名
• Iprisklevel

如果我点击第二个单选按钮，我想列的顺序是：

• 组
• ASSETNAME
• 资产
• 类型名
• Iprisklevel

下面是我的XAML的示例：

 ＆LT; ASP：GridView控件ID =dgAssets=服务器的AutoGenerateColumns =FALSEAllowPaging =真
            DataKeyNames =IDAllowSorting =真OnPageIndexChanging =dgAssets_PageIndexChanging
            宽度=100％OnRowCommand =dgAssets_RowCommandOnRowDataBound =dgAssets_RowDataBound
            OnSorting =dgAssets_Sorting＆GT;
            ＆LT;列＆GT;

                ＆LT; ASP：的TemplateField可见=假＆GT;
                    ＆LT;的ItemTemplate＆GT;
                        ＆所述;％＃的DataBinder.Eval（的Container.DataItem，ID）％＆GT;
                    ＆LT; / ItemTemplate中＆GT;
                ＆LT; / ASP：的TemplateField＆GT;
                ＆LT; ASP：的TemplateField SORTEX pression =ASSETNAME＆GT;
                    ＆LT;的ItemTemplate＆GT;
                        ＆LT;％＃的DataBinder.Eval（的Container.DataItem，ASSETNAME）％＆GT;
                    ＆LT; / ItemTemplate中＆GT;
                ＆LT; / ASP：的TemplateField＆GT;
                ＆LT; ASP：的TemplateField SORTEX pression =资产＆GT;
                    ＆LT;的ItemTemplate＆GT;
                        ＆LT;％＃的DataBinder.Eval（的Container.DataItem，资产）％＆GT;
                    ＆LT; / ItemTemplate中＆GT;
                ＆LT; / ASP：的TemplateField＆GT;
                ＆LT; ASP：的TemplateField SORTEX pression =组＆GT;
                    ＆LT;的ItemTemplate＆GT;
                        ＆LT;％＃的DataBinder.Eval（的Container.DataItem，组）％＆GT;
                    ＆LT; / ItemTemplate中＆GT;
                ＆LT; / ASP：的TemplateField＆GT;
                ＆LT; ASP：的TemplateField SORTEX pression =类型名称＆GT;
                    ＆LT;的ItemTemplate＆GT;
                        ＆LT;％＃的DataBinder.Eval（的Container.DataItem，类型名称）％＆GT;
                    ＆LT; / ItemTemplate中＆GT;
                ＆LT; / ASP：的TemplateField＆GT;
                ＆LT; ASP：的TemplateField SORTEX pression =IPRISKLEVEL＆GT;
                    ＆LT;的ItemTemplate＆GT;
                        ＆LT;％＃的DataBinder.Eval（的Container.DataItem，IPRISKLEVEL）％＆GT;
                    ＆LT; / ItemTemplate中＆GT;
                ＆LT; / ASP：的TemplateField＆GT;

            ＆LT; /列＆GT;
        ＆LT; / ASP：GridView控件＆GT;
 

解决方案

而不是增加在设计模式中的列，它可能是一个想法，动态地使用C＃code添加它们。这将允许你命令他们任何你喜欢的方式。

$ C $下动态地添加列：

  DataTable的DT = yourDataTable;
的foreach（COL的DataColumn在dt.Columns）
{
    绑定列bfield =新的绑定列（）;
    bfield.DataField = col.ColumnName;
    bfield.HeaderText = col.ColumnName;
    dgAssets.Columns.Add（bfield）;
}
 

I have two radiobuttons. If I click the first radiobutton I want the column's order to be:

• AssetName
• Asset
• Groups
• TypeName
• Iprisklevel

If I click the second radio button I want the column's order to be:

• Groups
• AssetName
• Asset
• TypeName
• Iprisklevel

Here is a sample of my XAML:

<asp:GridView ID="dgAssets" runat="server" AutoGenerateColumns="False" AllowPaging="True"
            DataKeyNames="ID" AllowSorting="True" OnPageIndexChanging="dgAssets_PageIndexChanging"
            Width="100%" OnRowCommand="dgAssets_RowCommand" OnRowDataBound="dgAssets_RowDataBound"
            OnSorting="dgAssets_Sorting">
            <Columns>

                <asp:TemplateField Visible="False">
                    <ItemTemplate>
                        <%# DataBinder.Eval(Container.DataItem, "ID")%>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField SortExpression="ASSETNAME">
                    <ItemTemplate>
                        <%# DataBinder.Eval(Container.DataItem, "ASSETNAME")%>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField SortExpression="ASSET">
                    <ItemTemplate>
                        <%# DataBinder.Eval(Container.DataItem, "ASSET")%>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField SortExpression="GROUPS">
                    <ItemTemplate>
                        <%# DataBinder.Eval(Container.DataItem, "GROUPS")%>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField SortExpression="TYPENAME">
                    <ItemTemplate>
                        <%# DataBinder.Eval(Container.DataItem, "TYPENAME")%>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField SortExpression="IPRISKLEVEL">
                    <ItemTemplate>
                        <%# DataBinder.Eval(Container.DataItem, "IPRISKLEVEL")%>
                    </ItemTemplate>
                </asp:TemplateField>

            </Columns>
        </asp:GridView>

解决方案

Instead of adding the columns in design mode, it might be an idea to add them dynamically using C# code. Which will allow you to order them any way you like.

Code for dynamically adding columns:

DataTable dt = yourDataTable;
foreach (DataColumn col in dt.Columns)
{
    BoundField bfield = new BoundField();
    bfield.DataField = col.ColumnName;
    bfield.HeaderText = col.ColumnName;
    dgAssets.Columns.Add(bfield);
}
