Hi there. I need some help please.

I add a unbound field to my grid to allow the user to enable/disable an option. I want to add a checkbox to the label and when the user checks/unchecks that checkbox I want to check or uncheck all the rows in the grid.

Can you please help me?

 In code I add the selecor field to the grid:

        Dim SelectorField As New UnboundField
        SelectorField.DataType = GetType(Boolean)
        SelectorField.Column = 0
        SelectorField.Settings.LabelWidth = 20
        SelectorField.Settings.CellWidth = 20
        SelectorField.Settings.AllowEdit = True
        pLayout.Fields.Add(SelectorField)

Thanks.

Did you want to know the best way to assign a checkbox to an unbound field or how to check/uncheck all the checkboxes in the grid when the user checks or unchecks one checkbox? Would this checkbox be in the header which would be a quick way to uncheck all the checkboxes in a column?

Thanks,

 Hi Curtis.

 So far I managed to add the unbound field to the grid and I raise an event when the checkbox on a row is checked and unchecked. I also have a property that allows the developer to check and uncheck rows in code.

Now all I need is to add another checkbox onto the screen that the user can use as a "quick" check all or uncheck all. The best place to add such a checkbox would be the in the LabelPresenter for the unbound checkbox field.

How do I define a LabelPresenterStyle that only contains an XamCheckBox? And how do I hook into the checked and unchecked events for that XamCheckBox?

Thank you very much :)

I have done this by overwriting the default control template for the Label Presenter. 

<Style TargetType="{igDP:LabelPresenter}">

   <Setter Property="Template">

      <Setter.Value>

        <ControlTemplate TargetType="{igDP:LabelPresenter}">

 <CheckBox Checked="CheckedHandler" Unchecked="UncheckedHandler" />

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>
