Hi Ruslan,

I am not completely clear on what control you are referring to, but I will assume you mean the RadComboBox. If yes, then you are trying to solve a problem where the content is longer than the box and you want it to scroll? After reading my answer, you can check out this link to learn more on controlling the appearance of the RadComboBox

I've created an example of a ComboBox (at the end of this post) for you that demonstrates the ability to indiviually control each dropdown list items. Look through it and see the Comments I've placed for you. Copy and paste this code into your project to see what I've done for you. Notice in the third item, I have explicitly set it to show a scrollbar when the content becomes larger than the width. I think this is what you are looking for.

If this isn't what you were looking for or if you are talking about a different control, let me know. If you provide your code, I will be able to help you find a solution.

Good Luck,
Lancelot

Thanks, I needed to make the same decision but for RadDropDownButton, I attached a screenshot, which is drawn too long, issues a drop-down element of the tree, and we should limit it like that.

Hi Ruslan,

After playing with your idea for a while, I think it would be better for you to use a RadComboBox and set a maximum height for the ComboBoxItem. That way you can still have the same appearance but when the user expands the year, it would stay withing the maximum height of the Item, but offer them a vertical scroll bar. I've written an example below for you.

The ComboBox hold the treeview, for which you can bind your data to (I'm sorry I cant translate the text in the image but they look like dates). So the user can drop down the box to get to the RadTreeView. When they expand the RadTreeView, the scrollBar will appear to right if the list is too long for your maximum height. When the user makes the selection inside the TreeView, the comboBox will collapse automatically.

Good luck,
Lancelot

Ruslan,

I looked at your code and I added in two important properties, these properties are the one I was telling you about in my other reply. I've attached a screenshot of what you need to do. Let me know if this doesnt work. If it does work, please mark this post as "Answer" for other people to find who have the same problem as you.

Good Luck!
