Topic: Strange problem with DropDownList

rob.dataccess premium asked 4 years ago


I know that you don't support ASP.NET officially but I found a strange issue with the "asp" component named DropDownList (is the equivalent of the ComboBox). The web application that I'm developing has a Master Page where there are all the reference to the MDB "core" and where I "designed" a navbar+sidebar menu. Now the issue: in one of the page I dropped a DropDownList component (asp, not MDB) that is loaded "code behind" from a SQL table. So...I found that if I reference href="css/mdb.min.css" (that is saved locally into folders) the DropDownList strangely becomes invisible, if I reference the cdn href="" (I think it's the free version) the DropDownList appears but the "sidebar" of the menu disappears. The same thing happens with CheckBoxes. Why this...thing? Is there a workaround? Thank you, regards.

Unfotunately I'm not able to paste the whole code of the page, if I press "CTRL+K" appears "enter code here" but after I copied the code only the title tag appears...

Hi Piotr,

if you paste the code below into an ASP page, when you "execute" the page the DropDownList is invisible.


If you change ONLY the reference to the MDB css

<link rel="stylesheet" href="css/mdb.min.css"/>


<link href="" rel="stylesheet" />

the DropDownList will be visible. If you need further info don't hesitate to contact me. Thank you,

Maybe you have some extra CSS what overwrite mdb.css? I can only add this problem to our list to do because we don't work with ASP.NET environment I can't even 'reproduce' this problem for that moment, with a basic environment it's working correctly. Have a nice day.

Hi Piotr,

no I don't have any other CSS that overwrite mdb.css.By the way, I found a way to "workaround" the problem but it would be nice if you will support ASP.NET in the future. Thanks for now, regards.

Do you have some example of that? We can't help if we can't see a problem especially when we don't support ASP.NET technology.
