Can CheckBox be set as "ReadOnly"?

[Ben Hayat]

Is it possible to set the CheckBox (Check State property) as readonly, so the user can not change it?
I would like to use this checkbox to tell the user if this node is a "Private" or "Public" by using the checkbox. However, the program will read certain data from database to determine that and not the user. So at runtime I like to set that but the user can not change it.
If not, how else can I show some sort of indicator that the item is private or public?
Thanks!

Hi Ben Hayat,

You can edit the default style of the RadTreeViewItem and apply it to particular items.
You can modify the CheckBox to be Disabled for or to exclude it from the template.
The described approach is realized in the attached solution, so please give it a try and let me know if it satisfies you.

Thank you Petar for the reply and test program. I'll look through it. Meanwhile, for my case I'm trying to figure out if there is a better solution than using disabled checkbox.

Hi Ben Hayat,

Actually, it appears that there is an easier way to achieve the desired effect. you can explicitly set the OptionType to None like so:

<telerik:RadTreeView Name="treeView"
                                 Width="150"
                                 HorizontalAlignment="Left"
                                 IsOptionElementsEnabled="True"
                                 ItemsOptionListType="CheckList">
                <telerik:RadTreeViewItem Header="Sport" OptionType="None" />
                <telerik:RadTreeViewItem Header="EnterTainment" />
            </telerik:RadTreeView>

Please let us know if this approach helps you.

Hi Petar;

I'm not sure the OptionType=None, would help me. At runtime I do want to set the Item to "Checked" or "Unchecked", except I don't want the user to be able to change it. Are you saying with OptionType=none I can do that?

Thanks!

Hello Ben Hayat,

Setting the OptionType of some particular RadTreeViewItem doesn't restrict you to change its IsChecked property. You can examine this in the attached solution.
However, you can elaborate more on your scenario; how will the data be loaded, how will the user change the CheckState ( IsChecked  of the items, how you bind your tree and etc. This way we could provide you with the best approach for your situation. A runnable sample would also be highly appreciated. Thank you for your cooperation.

Kind regards,
