Action upon selecting a line in a grid

问题

I'd like to enable or disable a button upon selecting a line in a grid, here's what I tried for now :

    public virtual void ARRegister_RowSelected(PXCache sender, PXRowSelectedEventArgs e)
    {
        ARRegister row = e.Row as ARRegister;
        if (row == null) return;
        UnProcessLettering.SetEnabled(row.GetExtension<ARRegisterLeExt>().LettrageCD != null);
    }

And I've set the syncposition as true in my grid. But nothing changes when I select a row in which LettrageCD is not null or is null.

Edit : it seems my question is a duplicate : Is there any event triggered when highlighting a row? (didnt find it during my first search :( )

Instead of calling SetEnabled on the PXAction, use the StateColumn property on your button aspx declaration.

When you declare your button, you specify a Boolean DAC field that will enable/disable the button based on it's value. Note that the button needs the DependOnGrid property set to the ID of the grid to get the selected row:

<px:PXToolBarButton Text="Button A" DependOnGrid="grid" StateColumn="IsButtonVisible">

IsButtonVisible is a custom unbound Boolean DAC field:

#region IsButtonVisible
public abstract class isButtonVisible : IBqlField
{
}

protected bool? _IsButtonVisible;
[PXBool]
[PXUIField(DisplayName = "Is Button Visible", Enabled = false, Visible = false)] 
public virtual bool? IsButtonVisible
{
    get
    {
        return _IsButtonVisible;
    }
    set
    {
        _IsButtonVisible = value;
    }
}
#endregion

You can set the value of IsButtonVisible in the RowSelected event based on your business logic:

protected virtual void DAC_RowSelected(PXCache sender, PXRowSelectedEventArgs e)
{
    DAC row = e.Row as DAC;

    if (row != null)
    {
        bool yourCondition = ???;
        row.IsButtonVisible = yourCondition;
    }
}
