Asked On May 25, 2016 04:28 PM UTC

Hello,

I have a combodropdown with a treeviewadv in it as the popupcontrol. Everything works fine except the dropdown height of the combodropdown is way too tall and I don't know how to change it. I can change the dropdownwidth of the combodropdown with a public property. How do I change the dropdownheight?

Thanks,
Adam

Also is there a way to make the textfield of the combodropdown read only while still allowing the user to dropdown and edit the popupcontrol?

Hi Adam, 
 
Thank you for contacting Syncfusion support. 
 
The reported requirement can be achieved by increasing the height of the custom control which is added as drop down in ComboDropdown. Please refer to the below code snippet. 
 
Code Example : C# 
//To increase the height of TreeViewAdv 
 
this.treeViewAdv1.Height = 400; 
 
 
We have prepared  a sample and video for your reference which can be downloaded from the below location.

Thanks Keerthana. That works for the dropdown height.

What about the text field in the combodropdown? Can I make that readonly? The user shouldn't be able to edit it.

Thanks,
Adam
