wpf command parameter from other object

You can do this by setting the ElementName in the binding. Here's an example:

<TextBox x:Name="textBox"/>
<Button Content="Button" 
        Command="{Binding ButtonCommand}" 
        CommandParameter="{Binding ElementName=textBox, Path=Text}"/>

The following XAML should work to pass the Text from the TextBox as Parameter to your command.

<TextBlock x:Name="searchBox" />

<Button Command="{Binding MyButtonInViewModel}" 
        CommandParameter="{Binding Text, ElementName=searchBox}"/>
