I am getting following script error when I tried to navigate to a tab in RadTabStrip.

Microsoft JScript runtime error: Unable to get value of the property 'apply': object is null or undefined

Checkboxes

Hopefully there is a solution out there for our issue.

We have a treeview that can have child nodes, is displayed in a relation way (parent, child etc). However, we do not want the checking of a child node to automatically check the parent node(s).

The treeview is a hierarchical representation of geographical areas and we want to be able to select "Chicago" without automatically selecting "Illinois" and "USA".

Does anyone know if there is a way to achieve this?

Thanks,

Greg

Detach EditForm from Parent

Hi,

I implemented a copy command which takes the current row and creates a copy which is then edited. But I don't want that the edit form is displayed below the item I used as source. I want it to be displayed at the top (like the insert form).
How can I achieve this in the ItemDataBound event? I "Just" want to remove the ParentItem from the GridEditFormItem.

Thanks for your help!
