GridViewColumn.AdaptivePriority Property

Gets or sets the priority of column hiding in adaptive mode.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v20.2.dll

Declaration

[DefaultValue(0)]
public int AdaptivePriority { get; set; }
<DefaultValue(0)>
Public Property AdaptivePriority As Integer

Property Value

Type Default Description
Int32

0

An Int32 value specifying the column priority.

Remarks

When the ASPxGridViewAdaptivitySettings.AdaptivityMode property is set to HideDataCells, the ASPxGridView control can automatically resize or hide grid columns once cell text becomes truncated. Use the AdaptivePriority property to control the order of column hiding.

The bigger the value of the AdaptivePriority property is, the earlier the column will be hidden. If columns have the same priority, the hiding order is determined by the WebColumnBase.VisibleIndex property.

The hidden column data can be displayed by clicking the show adaptive detail button.

Example

The following example illustrates how to use the AdaptivePriority property.

Web Forms approach:

NOTE

For a full example, see the ASPxGridView - Customization Dialog demo.

<dx:ASPxGridView ID="Grid" runat="server" DataSourceID="ProductsDataSource" 
    EnableRowsCache="false" Width="100%">
    <Columns>
        <dx:GridViewDataTextColumn FieldName="ProductName">
            <Settings AutoFilterCondition="Contains" />
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataComboBoxColumn FieldName="CategoryID" Caption="Category Name" SortIndex="0" SortOrder="Ascending" AdaptivePriority="1">
            <PropertiesComboBox DataSourceID="CategoriesDataSource" ValueField="CategoryID" TextField="CategoryName" ValueType="System.Int32" />
            <Settings AllowHeaderFilter="True" AllowAutoFilter="False" SortMode="DisplayText" />
            <SettingsHeaderFilter Mode="CheckedList" />
        </dx:GridViewDataComboBoxColumn>
        ...
    </Columns>
</dx:ASPxGridView>

MVC approach:

NOTE

For a full example, see the GridView - Customization Dialog demo.

@Html.DevExpress().GridView(settings => {
    settings.Name = "GridView";
    settings.SettingsCustomizationDialog.Enabled = true;
    ...
    settings.Columns.Add(c => {
        c.FieldName = "ProductName";
        c.Settings.AutoFilterCondition = AutoFilterCondition.Contains;
    });
    settings.Columns.Add(c => {
        c.FieldName = "CategoryID";
        c.Caption = "Category Name";
        c.SortIndex = 0;
        c.SortOrder = DevExpress.Data.ColumnSortOrder.Ascending;
        c.AdaptivePriority = 1;
        c.Settings.AllowHeaderFilter = DefaultBoolean.True;
        c.Settings.AllowAutoFilter = DefaultBoolean.False;
        c.Settings.SortMode = DevExpress.XtraGrid.ColumnSortMode.DisplayText;
        c.SettingsHeaderFilter.Mode = GridHeaderFilterMode.CheckedList;
        c.EditorProperties().ComboBox(cb => {
            cb.DataSource = NorthwindDataProvider.GetCategories();
            cb.TextField = "CategoryName";
            cb.ValueField = "CategoryID";
            cb.ValueType = typeof(int);
        });
    });
}).Bind(Model).GetHtml()
