Hello vertisit,

Thank you for posting in our community.

I followed the steps that you suggested but I was unable to reproduce the issue that you are describing. What I noticed in the code snippet with the aspx declaration of the WebDropDown is that the Visible property is set to false. In this scenario the WebDropDown is not going to be visible on the page. Otherwise, when this property is set to true the control is visible on the page and selected values are correctly displayed in the WebDropDown`s input.

I am attaching the sample project that I used to test this for your reference. Please run this sample on your computer; whether or not this works correctly on your side may help indicate the nature of this issue.

If this project is not an accurate demonstration of what you are trying to achieve please feel free to modify it and send it back to me or send a small isolated sample of your own where the issue is reproducible.

Additionally, since you are using version 12.2.20122.1007 of NetAdvantage, which is the RTM version of the product what I can suggest is downloading the latest service release available for your version, which is 12.2.10122.2257. This could be achieved by following these steps:

1) Go to http://es.infragistics.com and log with your account

2) Select "Account". This will open the "My keys and downloads" page.

3) Select your product from the product list.

4) Select "Service releases" tab.

There you will find the latest service release available for download.

I hope you find my information helpful.

Please let me know if you need any further assistance with this matter.
