ASPxGridView.FocusedRowIndex Property
Specifies the index of the focused row.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v24.2.dll
NuGet Package: DevExpress.Web
Declaration
Property Value
| Type | Description |
|---|---|
| Int32 | The focused row index. |
Remarks
ASPxGridView identifies rows by their indices. The FocusedRowIndex property specifies the index of the focused row.
Set the AllowFocusedRow property to true to enable row focus. Change the FocusRowIndex property value to move focus to the corresponding row within the current page. When the row focus changes, the server-side ASPxGridView.FocusedRowChanged or the client-side ASPxClientGridView.FocusedRowChanged event fires (based on the ProcessFocusedRowChangedOnServer property value). If you navigate to another page, the row loses focus.
When row focus is disabled, the FocusedRowIndex property returns -1. To identify the row being edited, use the EditingRowVisibleIndex property.
Web Forms Example
The following example shows how to use the FocusedRowIndex property:
<dx:ASPxGridView ID="gridView" runat="server" AutoGenerateColumns="False" KeyFieldName="CategoryID"
OnDataBound="gridView_DataBound" OnFocusedRowChanged="gridView_FocusedRowChanged">
<SettingsBehavior AllowFocusedRow="true" ProcessFocusedRowChangedOnServer="true" />
<Columns>
<dx:GridViewDataTextColumn FieldName="CategoryID" ReadOnly="True" VisibleIndex="0">
<EditFormSettings Visible="False" />
</dx:GridViewDataTextColumn>
<dx:GridViewDataTextColumn FieldName="CategoryName" VisibleIndex="1" />
<dx:GridViewDataTextColumn FieldName="Description" VisibleIndex="2" />
</Columns>
</dx:ASPxGridView>
protected void gridView_FocusedRowChanged(object sender, EventArgs e) {
ASPxGridView grid = sender as ASPxGridView;
Response.Cookies[grid.ID]["FocusedIndex"] = 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]["FocusedIndex"]);
}
MVC Example
@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()
