Rename a Directory

[Anthony]

Hi, I am getting an error when I try to rename a directory in the File Explorer. To reproduce this error I right-click the item in either the treeview or gridview, change the name, and either hit enter or click somewhere else on the screen to make the changes. When I hit enter the following error appears on my screen. This error only appears when I am renaming a directory, it doesn't happen when I am renaming a file.

System Error: System.ArgumentOutOfRangeException: Length cannot be less than zero. Parameter name: length at System.String.InternalSubStringWithChecks(Int32 startIndex, Int32 length, Boolean fAlwaysCopy) at Telerik.Web.UI.RadFileExplorer.RenameTreeNode(RadTreeNode node, String newName) at Telerik.Web.UI.RadFileExplorer.RadTreeView1_NodeEdit(Object sender, RadTreeNodeEditEventArgs e) at Telerik.Web.UI.RadTreeView.OnNodeEdit(RadTreeNodeEditEventArgs e) at Telerik.Web.UI.RadTreeView.RaisePostBackEvent(String eventArgument) at Telerik.Web.UI.RadTreeView.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.String.InternalSubStringWithChecks(Int32 startIndex, Int32 length, Boolean fAlwaysCopy) at Telerik.Web.UI.RadFileExplorer.RenameTreeNode(RadTreeNode node, String newName) at Telerik.Web.UI.RadFileExplorer.RadTreeView1_NodeEdit(Object sender, RadTreeNodeEditEventArgs e) at Telerik.Web.UI.RadTreeView.OnNodeEdit(RadTreeNodeEditEventArgs e) at Telerik.Web.UI.RadTreeView.RaisePostBackEvent(String eventArgument) at Telerik.Web.UI.RadTreeView.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Hi,

Which version of the RadControls are you using? Does this happen with the default content provider or a custom one? Try updating to the latest official build and if that doesn't help, send us some more information about your scenario - e.g. how is the file explorer configured, a screenshot of the control before you try to rename, etc.
