Need help on setting column attributes dyamically

[Alessandro]

Hi I am binding the grid to a list of arbitrary objects. For isntance, the object might be Person

class Person
{
  bool: Selected {get; set;}
  string FirstName {get; set;}
  string LastName {get; set;}
...
}

I have auto column generation enabled so I'm not using any templates.

I want all columns to be read-only except for the first which will be used to determine whether a row is selected or no (I have multiselect enabled).

Do you have any suggestions on how to accomplish this? Perhaps set the binding mode to TwoWay and then loop through the columns making them readonly perhaps?

Hello Xavier,

 You can access auto-generated columns (and set various columns properties) using AutoGeneratingColumn event.

Best wishes,

Vlad - Wow! That was fast. Thanks!

Before I do use that approach, allow me to ask this.  Is there a way to determine the selected item (or items) when using the MVVM approach? I'm binding to an ObservableCollection.

One way to store the selected value in the View-Model, is to make a reference object in the View-Model and use the Selection Change Event from the View to change the View-Model's reference object.

public View()
{
    InitializeComponent();
    this.GridView.SelectionChanged += new EventHandler<SelectionChangeEventArgs>(GridView_SelectionChanged);
}
void GridView_SelectionChanged(object sender, SelectionChangeEventArgs e)
{
    ((MyViewModel)this.DataContext).currentSelectedValue = ......
}

When I have a question about accessing the the V from the VM, I generally go back and see what I'm really trying to do.  Alternatively you can make a Command, but to be honest, I haven't done that yet.
