ASPxClientGridView.SetFocusedRowIndex(visibleIndex) Method

Moves focus to the specified row.

Declaration

SetFocusedRowIndex(
    visibleIndex: number
): void

Parameters

Name	Type	Description
visibleIndex	number	The row index.

Remarks

Set the AllowFocusedRow property to true to enable row focus.

Call the SetFocusedRowIndex(visibleiIndex) method to focus 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.
