Whenever the DropDownTree is placed near other expanding controls such as standard date pickers, it causes those controls to appear behind the DropDownTree. I have attempted various solutions including using inline style, setting z-index for .RadDropDownTree_Default, increasing the z-index for other controls significantly greater than 100000, and applying styles through jQuery. However, regardless of what I tried, the expanded controls still end up positioned behind the input area of RadDropDownTree.
Is there a way to set lower z-index values for RadDropDownTree to prevent it from overlapping with other expanding controls?
