Thanks for your reply. We got solution for all the problems except the problem of fields / controls disappearing which we guess occurs when we use splitter control and tabs in same page, however we are not sure. Here is detailed explanation of problem:
We have page Test.aspx in which we are using splitter control and two Rad panes. In one of the Rad panes, we have link buttons and in another Rad pane(Right one) we are using RadTabs as shown in screenshot (FieldDisAppearing-I.JPG). Our problem is that some of the controls in right Rad pane get disappeared suddenly after loading of page. E.g. fields like Reopen date, Report Due date which are visible initially, get disappeared within seconds after the page is loaded.
I have attached screenshots of my page. In first screen shot (FieldDisAppearing-I), you can see all controls are visible (screen shot was taken just before the page was loaded) and in second one (FieldDisAppearing-II), controls like Reopen date, Report Due date got disappeared when the page was loading was complete. I have also attached Html code of this page.
Can you please suggest us some solution on this?
