ASPxGridViewBehaviorSettings.AllowFocusedRow Property

Specifies whether row focus is enabled.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

[DefaultValue(false)]
public bool AllowFocusedRow { get; set; }

VB.NET

<DefaultValue(False)>
Public Property AllowFocusedRow As Boolean

Property Value

Type	Default	Description
Boolean	false	true to enable row focus; otherwise, false.

Property Paths

You can access this nested property as listed below:

Object Type	Path to AllowFocusedRow
ASPxGridView	.SettingsBehavior .AllowFocusedRow
GridViewProperties	.SettingsBehavior .AllowFocusedRow

Remarks

Set the AllowFocusRow property to true to enable row focus. When focus changes, the control raises the server ASPxGridView.FocusedRowChanged or the client ASPxClientGridView.FocusedRowChanged event (based on the ProcessFocusedRowChangedOnServer property value) and sets the FocusedRowIndex property to the index of the focused row.

The control can focus only one row at a time within the current page. If you navigate to another page, the row loses focus. To select multiple rows within different pages, use row selection.

When row focus is disabled, the control behaves as follows:

• The FocusedRowIndex property returns -1.
• The FocusedRowChanged event does not fire.
• Focused row style settings are not in effect.

To identify the row being edited, use the EditingRowVisibleIndex property.

Limitations

• When cell merge is enabled, ASPxGridView does not support row focus.

• For the ASPxGridLookup control, the AllowFocusedRow property is always set to true.

Web Forms Example

The examples below show how to use the AllowFocusedRow property.

ASPX

<dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False"
    ClientInstanceName="grid" KeyFieldName="CategoryID">
    <SettingsBehavior AllowFocusedRow="true" />
    <SettingsDetail ShowDetailRow="True" AllowOnlyOneMasterRowExpanded="true" />
    <ClientSideEvents DetailRowExpanding="OnDetailRowExpanding" />
    <Columns>
        <%--...--%>
    </Columns>
    <Templates>
        <DetailRow>
            <dx:ASPxGridView ID="ASPxGridView2" runat="server" KeyFieldName="ProductID"
                AutoGenerateColumns="False">
                <Columns>
                    <%--...--%>
                </Columns>
            </dx:ASPxGridView>
        </DetailRow>
    </Templates>
</dx:ASPxGridView>

JS

function OnDetailRowExpanding(s, e) {
    grid.SetFocusedRowIndex(e.visibleIndex);
}

MVC Example

Razor

@Html.DevExpress().GridView(settings => {
    settings.Name = "GridView";
    settings.CallbackRouteValues = new { Controller = "Home", Action = "GridViewPartial" };
    settings.SettingsPager.PageSize = 5;

    settings.KeyFieldName = "EmployeeID";
    settings.Columns.Add("LastName");
    settings.Columns.Add("FirstName");
    settings.Columns.Add("City");
    settings.Columns.Add("Country");

    settings.PreRender = (s, e) => {
        var sender = (MVCxGridView)s;
        // Set the zero-based index of the focused row. 
        sender.FocusedRowIndex = 6;
    };
    // Enable row focus. 
    settings.SettingsBehavior.AllowFocusedRow = true;
}).Bind(Model).GetHtml()
