Hello Markus,

Thank you for the feedback. Please do not hesitate to let me know if you have any further questions on this matter.

... I don't understand the world anymore :(

An absolutely standard behavior does not work. I am quite disappointed.

I added my super new Idea.

Regards

Markus

Hello Marcus,

After working on the functionality that you are trying to achieve and doing some research, the ability to set the width of the dropdown of the XamComboEditor between the minimum and maximum values automatically has been determined to be a new product idea. You can suggest new Product Ideas for future versions (or vote for existing ones) at http://ideas.infragistics.com.

Steps to create your idea:

1.            Log into the Infragistics Product Ideas site at http://ideas.infragistics.com (creating a new login if needed).

2.            Navigate to the product / platform channel of your choice (e.g. WPF, Windows Forms, ASP.NET, HTML5 / Ignite UI, iOS / NucliOS, etc.)

3.            Add your product idea and be sure to be specific and provide as much detail as possible. Explain the context in which a feature would be used, why it is needed, why it can’t be accomplished today, and who would benefit from it. You can even add screenshots to build a stronger case. Remember that for your suggestion to be successful, you need other members of the community to vote for it. Be convincing!

The benefits of submitting the product idea yourself include:

-              Direct communication with our product management team regarding your product idea.

-              Notifications whenever new information regarding your idea becomes available.

Additional benefits of the Product Idea system include:

-              Ability to vote on your favorite product ideas to let us know which ones are the most important to you.  You will have ten votes for this and can change which ideas you are voting for at any time.

-              Allow you to shape the future of our products by requesting new controls and products altogether.

-              You and other developers can discuss existing product ideas with members of our Product Management team.

The product ideas site allows you to track the progress of your ideas at any time, see how many votes it got, read comments from other developers in the community, and see if someone from the product team has additional questions for you.

Thank you for contacting Infragistics.

Thanks for your example. There is no exception more.
But now there is the following problem (please see the modified sample):

Scenario 1:
- starting the app, there are no items assigned, when opening the combobox -> ok
- After this I fill the itemsource and open the combobox again -> not ok: width and hight are incorrect

Scenario 2:
- starting the app again and "fill the itemsource", when opening the combobox -> ok
- clearing the itemsource and open combobox again -> expected behvior ok
- filling the itemsource again and open combobox again -> not ok: width and hight are incorrect

I tried several variants, what event should handle the width ... but I couldn't find any solution for a standard optimal behavior.
The optimal behavior would be that the width and height would be set automatically between Min/Max-Sizes depending on the items.
I used devexpress before, and I had to do nothing to get this normal behavior.
Also I tried the default ComboBox -> it's simple working

Thanks for any help,

Markus
