I have the following problem and need help with a solution. The behaviour is sampled by the online demo for the radcombobox so I will not supply a sample here.
Steps to reproduce:
1. Navigate to ComboBox/Features demo (http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/checkboxes/defaultcs.aspx
2. Open the dropdown and click the "Check All" option so that all items are checked.
3. Click the "Get Checked Items"
This is the initial state of my ComboBox in my solution. Now I want to just remove all checks and select one of them.
4. I open the Combobox and click on the "Check All" option to remove all selections.
Well, nothing happens.You will have to click twice on "Check All" to remove them all. My users are frustrated!
I understand that this must be by design, but for me the most logical thing would be if "Check All" works as a toggle button. If all checked, remove, if no checked, check all.
Anyone have a solution/workaround to get my "Check All" to work as a toggle button from click one?
