Hide/Show Checkbox in treeview

[Shirya]

Hello,
I would like to know if it is possible to show checkboxes only on one level of the treeview.
For example:
what should i do if I  want to show a checkbox ONLY for the movies category (Sci-Fi, comedy,horror)
    Sci-Fi
         [ ] Movie-Sci-Fi #1
                 Actor #1
                 Actor #2
         [ ] Movie -Sci-Fi #2
               ...
               ...
    Comedy
          [ ] Movie-Comedy #1
                 ...
          [ ] Movie-Comedy #2
                 ....
    Horror
          [ ] Movie-Horror #1

i try to change the ShowCheckBox property of each nodes
    myNode.ShowCheckBox = True
    myNode.ShowCheckBox = false
but doesNt work
thanx

Hi Shirya,

Thank you for writing. The answer to your question is yes, however it is done rather awkwardly. It can be done by setting the CheckBoxes properties of the TreeView to true. When you do that, every node in the Tree view will have a checkbox. After this you have to recursively set the ShowCheckBox property to false, for all nodes that do not require a check box.

I hope this idea will be useful. Please write back if you have other questions.

Hello,

I set the ShowCheckBox property to false, but the node still shows a CheckBox, what is wrong?

RadControl Version 8.1.0.0

Hello Daniel,

Thank you for your question. This can only happen if you set ShowCheckBox property of the node to false before you set the CheckBoxes property of RadTreeView to true, at least as far as we know. Please provide more details if this is not your case. I am looking forward to your reply.

I now solved it:

RadTreeNode myNode = new RadTreeNode("DESCRIPTION");

myTreeView.Nodes.Add(myNode);

myNode.ShowCheckBox = false;

Just to clarify this - it seems that the ShowCheckBox property of a TreeNode is only honoured AFTER it has been added to the TreeView's nodes collection.

This seems like a bug to me...

Hi Grant Drury-Green,

This is not a bug but the natural order of the normal .NET property settings. If you set the ShowCheckBox property of a node before you add it to the tree view, when you add it, the tree view will overwrite the setting that is already there. For historical reasons ShowCheckBox is a normal property and not a RadProperty; if it was a RadProperty it would respect certain priority rules.

Write again if you need assistance with any other issues.

All the best,

Do you have ShowCheckBox analog for Core version? There is no such property

Hi Dima,

The following example shows this: Creating tree nodes with checkboxes | ASP.NET MVC TreeView Demo.

Please note that this is the WinForms forum and if you have any further question please post them here: UI for ASP.NET Core Forums - Telerik Community.

I hope this will be useful.
