WPF-Multiple Views on ObservableCollection
I have a viewmodel containing two CollectionViews defined.
One I am using for na开发者_JS百科vigation and data entry/edit. Another I want to use for filtering purpose and show the filteration in some Listview on the form.
I don't want the main view(used for DataEntry purpose) to get affected while I applying filteration on observablecollection.
Thanks in Advance!
As long as you're using separate collection views, changing one won't affect the other. That is the point of collection views - they're independent views on the same collection.
ok, Got it! and went ahead with the same idea. But when I did so, I get Error = "The calling thread cannot access this object because a different thread owns it.". Hence my filteration doesn't work.. Following is the code-
public ICollectionView Clients { get; set; } //Used for Data-navigation/modification
public ListCollectionView CodeView { get; set; } // to be used for filteration purpose on form.
string searchText = String.Empty;
public string CompanyCodeSearch
{
get { return searchText; }
set
{
try
{
searchText = value;
OnPropertyChanged("CompanyCodeSearch");
CodeView.Filter = new Predicate<object>(cmFilterData);
}
catch (Exception ex)
{
}
}
}
private bool cmFilterData(object item)
{
bool _filteredData = false;
try
{
var value = (item as cntClient);
if (value == null || value.CompanyCode == null)
return false;
_filteredData = value.CompanyCode.StartsWith(this.CompanyCodeSearch);
return _filteredData;
}
catch (Exception ex)
{
return false;
}
}
