DxGrid.IsRowFocused(Int32) Method
Identifies whether the row with the specified visible index is focused.
Namespace: DevExpress.Blazor
Assembly: DevExpress.Blazor.v24.1.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 |
|
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";
}
}
}
//...
