Problem deleting selectedRecords

[Pierre Smith]

Hi There I hope someone can help me

For some reason when I select lets say 10 items in my grid. And I then delete those records by using  

_grid.Table.SelectedRecords.DeleteAll();

then the first 8 records would delete correctly but the last 2 selected records would jump down a few rows to some other records and delete those records 

Can anyone help please

Hi Pierre, 

 

Thanks for using Syncfusion products. 

 

We had analyzed your query. We suspect that you are using BindingList datasource. If you are using BindingList datasource in your application, ListChangedEventHandler must be triggered with ListChangedType as ItemDeleted in RemoveAt() method of IBindingList. Please make use of the below code, 

 

Code example 

public event System.ComponentModel.ListChangedEventHandler ListChanged; 

 

public void RemoveAt(int index) 

{ 

    list.RemoveAt(index); 

    RaiseListChanged(ListChangedType.ItemDeleted, index); 

} 

 

void RaiseListChanged(ListChangedType type, int index) 

{ 

    if (ListChanged != null) 

        ListChanged(this, new ListChangedEventArgs(type, index)); 

}

Note 

If you are using any other datasource, can you please provide the simple sample. So that we can provide solution at the earliest. 

 

Please let us know if we misunderstood anything.
