bindinglist and modification

[Guillaume]

Hello,

I put a bindingList (loaded with database content) in my grid's DataSource.

Oon RowValidated, I want to save the added/modified Data item to the database.

Is there a safe way to know if RowValidated is after an Add, or an Edit ?

Thanks,

[Jack]

Hello Guillaume JAY,

You have two options to solve this issue:

1. You can check whether the Row property of the event argument is GridViewNewRowInfo. In this case you are validating a new row

2. You should get the DataBoundItem property of the row and check the RowState property. However, this will only work when the underlying data source is DataTable.

void radGridView1_RowValidating(object sender, RowValidatingEventArgs e)
{
    DataRowView dataRowView = e.Row.DataBoundItem as DataRowView;
    if (dataRowView != null)
    {
        bool addedRow = dataRowView.Row.RowState == DataRowState.Added;
    }
}

In addition, you can use the Tag property of GridViewRowInfo to save custom information. I hope this helps.

Best wishes,
