copied!<p>I have a DataGrid that I fill with a DataView (using DataContext). I have tried to do that in a separate thread but the UI still freezes. I want to prevent the UI from freezing when populating the DataGrid.</p> <p>Here is the code I made so far:</p> <pre><code>private void btnOK_Click(object sender, RoutedEventArgs e) { GetFieldsBLL getFieldsBLL = new GetFieldsBLL(); DataView dv = getFieldsBLL.GetWholeView(ViewName); Task task = new Task(() => ucDataExtracViewControl.PopulateGrid(dv)); task.Start(); } public void PopulateGrid(DataView dv) { dgView.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(delegate{ dgView.Columns.Clear(); dgView.AutoGenerateColumns = false; foreach (DataColumn column in dv.Table.Columns) { var gridColumn = new DataGridTextColumn() { Header = column.ColumnName, Binding = new Binding("[" + column.ColumnName + "]") }; dgView.Columns.Add(gridColumn); } dgView.DataContext = dv; DataView = dv; })); } </code></pre> <p>Thanks in advance!</p> <p>Edit: The reason why I recreate the columns is because some of the column names have a dot in their name. For instance “Job No.” doesn’t yield any data when using binding.
