DataBinding + DataTable as DataSource - very strange behaviour

[ElCachubrey]

Hi all There is a subtle bug what i can't resolve. Please help. snippet 1 this.bindingSource.DataSource = this.dataTable; this.bindingSource.DataSource = null; this.bindingSource.Dispose(); /* Fill method read data by using data reader for this table. When this table contains many records (about 150000) this operation (Fill) consume about 1 minute. */ this.dataTable.Fill(); snippet 2 /* this.bindingSource.DataSource = this.dataTable; this.bindingSource.DataSource = null; this.bindingSource.Dispose(); */ Now i comment all code above, and supposingly this don't have any matter as such as i just return all to initiali state. BUT Now this operation (Fill) consume about 30 seconds. */ this.dataTable.Fill(); Any idea please. 30 more seconds very critical for me. THANK.

Hi Guys I think 30 sec is enough time. but not desired. So i think if we are put a thread to do the file operatoion and give high leve thread.may be this help to you reduce the time consume. thanks
