Web Forms approach:
Note
For a full example, see the 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>
MVC approach:
Note
For a full example, see the Grid
@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()
