ASPxGridView.FocusedRowChanged Event

Fires after the focused row has been changed.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v19.2.dll

Declaration

C#

public event EventHandler FocusedRowChanged

VB.NET

Public Event FocusedRowChanged As EventHandler

Event Data

The FocusedRowChanged event's data class is EventArgs.

Remarks

The FocusedRowChanged event is raised when an end-user moves focus from one row to another or after the ASPxGridView.FocusedRowIndex property’s value has been changed in code.

If the ASPxGridViewBehaviorSettings.ProcessFocusedRowChangedOnServer property is set to false, the ASPxClientGridView.FocusedRowChanged event is handled on the client side without a callback to the server. Setting this property to true indicates that the final processing of the event should be performed on the server side, and so a round trip to the server is required. During such a round trip, the corresponding server-side FocusedRowChanged event is fired, which if handled, allows any desired server-side action to be performed.

Concept

Focused Row

Example

ASPX

<dx:ASPxGridView ID="gv" runat="server" AutoGenerateColumns="False" DataSourceID="ads"

    <SettingsBehavior AllowFocusedRow="true" ProcessFocusedRowChangedOnServer="true" />
    <Columns>
    ...
    </Columns>
    <Templates>
        <FooterRow>
            <dx:ASPxLabel ID="lbl" runat="server" Text="">
            </dx:ASPxLabel>
        </FooterRow>
    </Templates>
</dx:ASPxGridView>

protected void gv_FocusedRowChanged(object sender, EventArgs e) {
    ASPxGridView grid = sender as ASPxGridView;
    if(grid.FocusedRowIndex > -1){
        ASPxLabel label = grid.FindFooterRowTemplateControl("lbl") as ASPxLabel;
        label.Text = grid.GetRowValues(grid.FocusedRowIndex, "CategoryName").ToString();
