C# – WPF ListView GridViewColumn Double Click

clistviewxaml

I have a WPF ListView that opens a certain window when double clicked on a certain item inside the list view, but I have a problem. When I double click the GridViewColumn, that also opens up a certain window.
Is there a way to detect if the sender is a gridviewColumn or a listView item?
Thanks

I assume you're handling the MouseDoubleClick event of the ListView ? Instead, you should handle that event on the ListViewItem, not the ListView itself. You can do that easily by setting the event handler in the ListView's ItemContainerStyle :

...
<ListView ...>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}">
            <EventSetter Event="MouseDoubleClick" Handler="YourHandler" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>
...

Wpf – ListBox vs. ListView – how to choose for data binding

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

C# – Case insensitive ‘Contains(string)’

You could use the String.IndexOf Method and pass StringComparison.OrdinalIgnoreCase as the type of search to use:

string title = "STRING";
bool contains = title.IndexOf("string", StringComparison.OrdinalIgnoreCase) >= 0;

Even better is defining a new extension method for string:

public static class StringExtensions
{
    public static bool Contains(this string source, string toCheck, StringComparison comp)
    {
        return source?.IndexOf(toCheck, comp) >= 0;
    }
}

Note, that null propagation ?. is available since C# 6.0 (VS 2015), for older versions use

if (source == null) return false;
return source.IndexOf(toCheck, comp) >= 0;

USAGE:

string title = "STRING";
bool contains = title.Contains("string", StringComparison.OrdinalIgnoreCase);
