ASPxGridView.FocusedRowChanged Event

Fires when the row focus changes.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v24.1.dll

NuGet Package: DevExpress.Web

Declaration

public event EventHandler FocusedRowChanged

Event Data

The FocusedRowChanged event's data class is EventArgs.

Remarks

Set the ProcessFocusedRowChangedOnServer property to true to allow the control to fire the server-side FocusedRowChanged event.

The FocusedRowChanged event fires in the following cases:

If the ProcessFocusedRowChangedOnServer property is set to false, the control raises the client-side ASPxClientGridView.FocusedRowChanged event.

Example

In the example below, the control raises the FocusedRowChanged event to save and restore the focused row index on the server side.

<dx:ASPxGridView ID="gridView" runat="server" AutoGenerateColumns="False"
    OnDataBound="gridView_DataBound" OnFocusedRowChanged="gridView_FocusedRowChanged">
    <SettingsBehavior AllowFocusedRow="true" ProcessFocusedRowChangedOnServer="true" />
    <Columns>
        <%--...--%>
    </Columns>
</dx:ASPxGridView>
protected void gridView_FocusedRowChanged(object sender, EventArgs e) {
    ASPxGridView grid = sender as ASPxGridView;
    Response.Cookies[grid.ID]["FocudedIndex"] = grid.FocusedRowIndex.ToString();
    Response.Cookies[grid.ID].Expires = DateTime.Now.AddDays(1d);
}
protected void gridView_DataBound(object sender, EventArgs e) {
    ASPxGridView grid = sender as ASPxGridView;
    if(!IsPostBack)
    if (Request.Cookies[grid.ID] != null)
        grid.FocusedRowIndex = Convert.ToInt32(Request.Cookies[grid.ID]["FocudedIndex"]);
}
