DxPivotTable.WaitForDataLoadAsync() Method
Returns a task that completes when pending asynchronous data load operations are completed.
Namespace: DevExpress.Blazor.PivotTable
Assembly: DevExpress.Blazor.PivotTable.v26.1.dll
Declaration
public Task WaitForDataLoadAsync()Returns
| Type | Description |
|---|---|
| Task | A task that completes when pending asynchronous data load operations are completed. |
Remarks
When bound to a Server Mode data source, the Pivot Table component loads data asynchronously in small portions instead of loading the entire dataset. To ensure correct data operations, call WaitForDataLoadAsync before methods that read or modify Pivot Table data (GetFields) or change the component state (for example, CollapseAllColumns, LoadLayout, SetFilterCriteria):
<!-- ... -->
@code {
IPivotTable PivotTable { get; set; }
// ...
async Task ChangeSortOrder() {
PivotTable.BeginUpdate();
await PivotTable.WaitForDataLoadAsync();
PivotTable.GetFields().First().ChangeSortOrder();
PivotTable.EndUpdate();
}
}
You do not need to use this method when you bind the Pivot Table to an in-memory collection (list or array).
