Hello Sathiya,

The forum thread below contains the workaround which can be used until the issue is fixed: 

In general, the following code should be added/loaded somewhere after the script manager of the page, ideally near the closing </form> tag.

            Telerik.Web.UI.RadFileExplorer.prototype.set_currentDirectory = function (value, addToStack)
                //add to back/forward stack
                if ((null != this._actionsManager) &&
                    (value != this.get_currentDirectory()) &&
                    (false != addToStack)
                    this._updateBackForward(value); // Is true

                var currentDirectoryInputElement = this._getCurrentDirectoryElement();
                if (currentDirectoryInputElement) currentDirectoryInputElement.value = value;
                var tree = this.get_tree();
                var node = tree.findNodeByValue(value);
                if (node)

                    //we cannot use tree's scrollIntoView due to the tree/splitter declarations

                var textboxID = this.get_addressBox();
                if (textboxID)
                    var textbox = $get(textboxID);
                    if (textbox)
                        textbox.value = value;

                //update toolbar

Hello Telerik Team,

Do we have any update on this issue? Can this be prioritized?

Our end customers are dealing with long list of files daily and this scrolling issue is frustrating them.

If this is gonna take time, kindly provide a workaround atleast.
