Dear all,

I am trying to set several splitters to retrieve a look and feel similar to windows explorer.
I want one thin area at the top.
Underneath, I want an area on the left separated from the right by a Splitter bar.

First Problem: scroll bars

The code below almost work but I get both horizontal and vertical scroll bars while I would expect none.
I am trying to use 100% everywhere as I want to use the entire screen.
Any idea how to get rid of them?

Second Problem: useless javascript

You may have noticed that the javascript is useless (I inherited it from one of the samples).
But if I remove it, the entire page becomes wonky as if the first splitter had a width of 50% and the second a height of 0.
Does that make sense?

Many thanks

Hum... Don't rush! One at a time, please!

I have removed the javascript problem hence I am only looking at having a RadSplitter containing a Header and another RadSplitter

I have spotted a few articles mentioning the HeightOffset attribute but I still don't seem to get it right.
I want both RadSplitters to use 100% height of their respective areas

Am I asking too much of Telerik?
Come on... You can do it!

For the record...
I have just discovered that my problem seems to be RadPane2 rather than the splitter...

I am able to hide(remove?) the problem by disallowing scroll bars on RadPane2 and the HeightOffset on RadSplitter2 appears useless in this case

Although I don't understand it all yet, this will solve my problem.

Thanks Eric. You're a star!

Hello Eric,

Straight to your questions:

I built up a test demo based on the code provided in your initial post. However, I was not able to reproduce the unnecessary scrollbars and when I removed the script, nothing changed.
The HeightOffset property is used when you want to have an additional element outside the splitter but I did not see such in your code. Note, also, that by default when you have a RadSplitter nested in a RadPane, the splitter automatically resizes itself to occupy 100% of the RadPane and that is why it did not respect your setting. If you want to turn off this, you should set ResizeWithParentPane=false for the splitter and set the HeightOffset property along with Width, Height set to 100%.
Indeed, when you use a RadSplitter nested in a RadPane you should set the Scrolling of the parent pane to be None. This should be done because otherwise you will get double scrollbars if the content is too big - the first scrollbar will be generated by the splitter and the second one - by the RadPane.

In case you need further assistance, please open a new support ticket and send me a sample, fully runnable reproduction demo along with screenshots of the actual and the desired layout. Once I have a better understanding on your exact goal I will do my best to help.
