Remarks

When an end user types text in the filter row‘s cell or when the ASPxGridView.AutoFilterByColumn method is called, a filter condition is created based upon the value entered. This filter is then applied to the ASPxGridView. The comparison operator used in this filter condition is determined by the column’s AutoFilterCondition property.

If the AutoFilterCondition property is set to Default, the column’s comparison operator type is controlled by the ASPxGridView’s ASPxGridViewSettings.AutoFilterCondition property.

Example

The following example illustrates how to use the AutoFilterCondition property.

ASPX

<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>

Razor

@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);
        });
    });
