c# - how to disable default selection in dropdownlist in asp.net -

I want to disable default selection in the dropdown list in asp.net and also on the selection of particular data fields Displayed in the txtbox below. The dropdown below should be filled with system related data such as c: drive, d ... etc while dynamically running.

You can then add "--select--" to the dropdown list by editing item first. And set the appenddatabounditems to true. In this case you will select the first place instead of the first drive by default ... OK then use this function and call this function on the databed event of the dropdown list. Duplicate Items (Dropdown List DDL) to remove Zero {for (ii = 0; i

and call this function in the dropdownlist_databound () event.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you!
