Gets or sets the name of a data field (or an xml element’s attribute) which provides group texts.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v21.1.dll


public override string TextField { get; set; }

Property Value

Type Default Description


A string value that specifies the name of the required data source field.


The TextField property is in effect if the NavBarGroupDataFields control is bound to a data source (via the ASPxDataWebControlBase.DataSourceID or ASPxDataWebControlBase.DataSource property).

Use the TextField property to specify the bound data source’s data field (or an xml element’s attribute) which stores navbar group texts. The TextField property maps the NavBarGroup.Text properties of NavBarGroup objects to the specified data field’s values.

You can format the obtained texts by using the NavBarGroupDataFields.TextFormatString property.

If the TextField property of a data bound NavBarGroupDataFields control is not defined, the control can automatically obtain group texts from a data field whose name is “Text” (which is equal to the NavBarGroup.Text property’s name). You can also handle the ASPxNavBar.GroupDataBound event to manipulate a group’s settings as required.


In the code sample below, the ASPxNavBar control is bound to an XML file using a standard XmlDataSource component. The item/group NavigateUrlField and TextField properties are used to specify the names of data item attributes from which the corresponding item/group settings should be obtained. The ItemDataBound and GroupDataBound events are handled to add corresponding images to items and groups respectively.

The image below shows the result.


protected void ASPxNavBar1_ItemDataBound(object source, DevExpress.Web.NavBarItemEventArgs e) {
     System.Xml.XmlNode dataItem = ((e.Item.DataItem as IHierarchyData).Item as System.Xml.XmlNode);
     switch (dataItem.Name) {
          case "ctor":
               e.Item.Image.Url = "Images/ctor.gif";
          case "property":
               e.Item.Image.Url = "Images/property.gif";
          case "method":
               e.Item.Image.Url = "Images/method.gif";
          case "event":
               e.Item.Image.Url = "Images/event.gif";

protected void ASPxNavBar1_GroupDataBound(object source, DevExpress.Web.NavBarGroupEventArgs e) {
     e.Group.HeaderImage.Url = "Images/class.gif";
