"Must create DependencySource on same Thread as the DependencyObject" When Create GridView
10,389
As the error says Dependency Property and its corresponding binding have to be created on same thread
. It can't be set on different threads. Put the creation of grid on UI dispatcher too. Since your ListView View
DP is created on UI thread, hence its source property i.e. GridView
should also be on UI thread.
Application.Current.Dispatcher.Invoke((Action)(delegate
{
GridView grid = new GridView();
grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileName"]);
grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileType"]);
grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileDataModified"]);
grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileSize"]);
ListViewOp.View = grid
}));

I have a problem with thread.When I want set a GridView into a ListView as View in another thread.It display a message which said:
Must create DependencySource on same Thread as the DependencyObject.
// Create grid view GridView grid = new GridView(); // Add column // Name grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileName"]); // Type grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileType"]); // Data Modified grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileDataModified"]); // Size grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileSize"]); // Edit view Application.Current.Dispatcher.Invoke(new Action(() => ListViewOp.View = grid));
What am I doing?
