ASPxGridView.FocusedRowChanged Event

Fires when the row focus changes.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

public event EventHandler FocusedRowChanged

VB.NET

Public Event FocusedRowChanged As EventHandler

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:

• A user moves row focus.
• You change the FocusedRowIndex property value.
• You call the SetFocusedRowIndex(visibleIndex) method.

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.

ASPX

<dx:ASPxGridView ID="gridView" runat="server" AutoGenerateColumns="False"
    OnDataBound="gridView_DataBound" OnFocusedRowChanged="gridView_FocusedRowChanged">
    <SettingsBehavior AllowFocusedRow="true" ProcessFocusedRowChangedOnServer="true" />
    <Columns>
        <%--...--%>
    </Columns>
</dx:ASPxGridView>

C#

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"]);
}

VB

Protected Sub gridView_FocusedRowChanged(ByVal sender As Object, ByVal e As EventArgs)
    Dim grid As ASPxGridView = TryCast(sender, ASPxGridView)
    Response.Cookies(grid.ID)("FocudedIndex") = grid.FocusedRowIndex.ToString()
    Response.Cookies(grid.ID).Expires = DateTime.Now.AddDays(1R)
End Sub
Protected Sub gridView_DataBound(ByVal sender As Object, ByVal e As EventArgs)
    Dim grid As ASPxGridView = TryCast(sender, ASPxGridView)
    If (Not IsPostBack) Then
    If Request.Cookies(grid.ID) IsNot Nothing Then
        grid.FocusedRowIndex = Convert.ToInt32(Request.Cookies(grid.ID)("FocudedIndex"))
    End If
    End If
End Sub
