Question

我有一个填充了数据的gridview，并且基于Chekbox选择我想在editform上隐藏一个字段。任何人都可以请指导，最好隐藏客户端或服务器端代码的列？，请找到以下代码供您参考（下面是devexpress Grid中的4列（4个字段），当我们选中复选框时然后应该隐藏其中一列（下拉列表）。）。

<dx:GridViewDataTextColumn FieldName="Name" VisibleIndex="1"  Caption="Name">
</dx:GridViewDataTextColumn>
<dx:GridViewDataTextColumn FieldName="Email" VisibleIndex="2"  Caption="Email">
 </dx:GridViewDataTextColumn>
<dx:GridViewDataCheckColumn FieldName="IsGraduate" VisibleIndex="3" Caption="Is Graduate ">
</dx:GridViewDataCheckColumn>
<dx:GridViewDataComboBoxColumn Caption="Degree" FieldName="Degree" 
 ShowInCustomizationForm="True" VisibleIndex="4">
<PropertiesComboBox DataSourceID="DegreeDataSource" TextField="Degree"  ValueField="Id">
</PropertiesComboBox>
</dx:GridViewDataComboBoxColumn>

Answer 1

您是否尝试对必要的列使用EditFormSetting可见性？请看下面的例子

        <dx:GridViewDataComboBoxColumn FieldName="color" Caption="#" VisibleIndex="2" ReadOnly="True"
            Width="25px">
            <HeaderStyle HorizontalAlign="Center" />
            <PropertiesComboBox DataSourceID="ColoredStatusSource" TextField="name" ValueField="id"
                EnableSynchronization="False" IncrementalFilteringMode="Contains" ValueType="System.Int32">
            </PropertiesComboBox>
            <EditFormSettings Visible="False" />
        </dx:GridViewDataComboBoxColumn>

如果使用客户端事件隐藏列以防止回调，那会更好。使用以下代码作为指南：

    Protected Sub dgView_001_CellEditorInitialize(sender As Object, e As DevExpress.Web.ASPxGridView.ASPxGridViewEditorEventArgs) Handles dgView_001.CellEditorInitialize

    If e.Column.FieldName = "IsGraduate" Then

        Dim chk As DevExpress.Web.ASPxEditors.ASPxCheckBox = New DevExpress.Web.ASPxEditors.ASPxCheckBox()

        chk = TryCast(e.Editor, DevExpress.Web.ASPxEditors.ASPxCheckBox)

        chk.ClientInstanceName = "chkIsGraduate"

        chk.ClientSideEvents.CheckedChanged = "function(s, e){ //if checked = true, hide column you want to hide }"

   ElseIf e.Column.FieldName = "Degree" Then

        Dim cmb As DevExpress.Web.ASPxEditors.ASPxComboBox = New DevExpress.Web.ASPxEditors.ASPxComboBox()

        cmb = TryCast(e.Editor, DevExpress.Web.ASPxEditors.ASPxComboBox)

        cmb.ClientInstanceName = "cmbDegree"

   End If

   End Sub

请注意，您还应该将一个客户端实例名称分配给要隐藏的列，以便您在javascript中访问它。希望这可以帮助！：）
