Namespace: DevExpress.Blazor
Assembly: DevExpress.Blazor.v24.1.dll
NuGet Package: DevExpress.Blazor

public bool IsEditingRow(
int visibleIndex
)
Parameters
Name | Type | Description |

visibleIndex | Int32 | The row’s visible index. |
Returns
Type | Description |
---|---|
Boolean |

Remarks
Call the IsEditing() method to check whether the Grid is in edit mode. The IsEditingRow
method allows you to identify whether the specified row is being edited. The IsEditingNewRow() method returns whether a new or existing row is in edit mode.
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 IsEditingRow
method, call the WaitForRemoteSourceRowLoadAsync(Int32) method to ensure that the specified data row is loaded.
