DxGrid.IsRowFocused(Int32) Method

Identifies whether the row with the specified visible index is focused.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

public bool IsRowFocused(
    int visibleIndex
)

Parameters

Name	Type	Description
visibleIndex	Int32	The row’s visible index.

Returns

Type	Description
Boolean	true if the row is focused; otherwise, false.

Remarks

Use the IsRowFocused method to determine whether the row with the specified visible index is focused. You can use the IsDataItemFocused(Object) method to determine whether the row bound to the specified data item is focused.

Note

The Grid bound to an Instant Feedback Data Source or GridDevExtremeDataSource loads data asynchronously in small portions (instead of the entire dataset). Before you call the IsRowFocused method, call the WaitForRemoteSourceRowLoadAsync(Int32) method to ensure that the specified data row is loaded.

The following code snippet calls the IsRowFocused method in the CustomizeElement event handler to specify a custom background color for the focused row.

<DxGrid Data="@Data" PageSize="6"
        FocusedRowEnabled="true" CustomizeElement="Grid_CustomizeElement" >
    <Columns>
        <DxGridDataColumn FieldName="ContactName" />
        <DxGridDataColumn FieldName="CompanyName" />
        <DxGridDataColumn FieldName="City" />
        <DxGridDataColumn FieldName="Country" />
    </Columns>
</DxGrid>

@code {
    object Data { get; set; }
    void Grid_CustomizeElement(GridCustomizeElementEventArgs e) {
        if (e.ElementType == GridElementType.DataCell || e.ElementType == GridElementType.GroupCell) {
            if (e.Grid.IsRowFocused(e.VisibleIndex)) {
                e.Style = "background-color: red";
            }
        }
    }
    //...
}
