MultiColumn combo dropdown width

[Daniel]

Hi,

where can I adjust width of dropdown box if MultiColumnComboBox? I've tried MultiColumnComboBoxElement  and EditorControl  with DropDownWidth, but it appears as if it had no effect on width of dropdown.

Are you planning to extend help for MultiColumn combo? I hope you do.

Best regards,
Daniel

Hello Daniel,

I did not manage to reproduce the issue you have described. When I set the DropDownWidth of the MultiColumnComboBoxElement to a specific value, the drop-down portion is resized according to that value. I am attaching a very simple project to demonstrate the correct behavior.

If your scenario is different than mine, please open a new support ticket and send me a sample project which shows the wrong behavior. This will allow me to address any potential issue further and to give you more accurate assistance.

As to the documentation, we have plans to further develop it for RadMultiColumnComboBox in the next couple of months. Your feedback will be of great help if you share with us what help topic would you like to see there.

I am looking forward to your response.
 

Kind regards,

Thanks for the project Nikolay. When you set it explicitly in code, it works just fine. What is problem is design time functionality. Most of critical properties of MultiColumnComboBox which are set in design time don't save their values (i.e. generated designer code) and thus are lost. Example of such property is mentioned MultiColumnComboBoxElement.DropDownWidth . Generally speaking, if you set anything within MultiColumnComboBoxElement or EditorControl of combo, it doesn't save in designer code.

This together with faulty PropertyBuilder makes Q2 SP1 MultiColumnComboBox pretty much useless unless you are supposed to code every single property by hand. I urge you to fix it asap, I was waiting for SP1 with extensive use of multi column combo and if it keeps being this problematic, I have big problems very soon.

Thanks for your understanding and time.

Best regards,
Daniel

We apologize for this, Daniel. At the moment all properties that are exposed through the EditorControl (which is a RadGridView) are not serializable in design time. One of them, obviously is DropDownWidth. Our intent is to make them serializable, but we will need to fine-tune the PropertyBuilder first (the ProperyBuilder by the way is directly exposed from the RadGridView as well). This task is with highest priority and we will have results in the next couple of days.
