代码背后的SqlDataSource复选框

Question

I'm populating an ASP.NET checkbox from a SqlDataSource added on the .aspx page, and then I need to access it in code behind, but I'm running into an issue in which my method is happening before the checkbox is populated and so it is giving me an item count of zero.

How do I make sure the checkbox is populated by the SqlDataSource before I access it with code?

Answer 1

If the text label for the checkbox is getting populated, then a simple fix would be to put

if(!(chkBox.Text == "" || chkBox.Text == null))
{
     // Your function call, or actual function code.
}

before the offending code is run in your code behind. This code prevents the if statement from being true if the label isn't populated yet.
