It is not very clear, to me, what is you really ask. When you say "...I am unable to see the entered string in Xdata list...", do you mean you actually did a debugging run, examined the value in the variable "length" and saw its value is empty/null? Assume that is the case, then it is obviously the UI you created do not have a value assigned to the said text box.
Since you commented out the CommandMethod attribute, it is not clear how this code (the method LinCom()) runs or is called, from where. Also, if the ucWPF is only the UI class (as your comment indicates), then does the said text box in the WPF design (xaml file) has its "Text" property set to a value?
Shouldn't you need to show the UI to user so that user can enter a valid value into the said textbox, BEFORE you use the textbox' value for creating XData (or for whatever purpose)?
Other critiques:
1. It would be better to get user to get selections from Editor before starting a Transaction. That is, only start a Transaction when the selection result's status is PromptStatus.OK;
2. You do not create a single ResultBuffer as the XData and assign it to multiple selected entities. You should:
foreach (var selected in ss)
{
ResultBuffer rb=.....
ent.XData=rb;
}

I have used a palette "ps", in which I have placed the WPF "ucWPF". But the string "lentry" (which was length in the previous code) doesn't seem to get updated. The WPF is visible to the user as soon as the command "KPAL" is entered. Here is how the UI looks:
