Solution 1

For an ASP.Net button, OnClick refers to the server side event, the C# event. If you want to run JavaScript use the OnClientClick event. Note: Javascript will run first. If you return false, for example, you can prevent the button from posting back and running the C#.

Both OnClientClick and OnClick can be used.
