解决方案

发布这么多代码并没有给我任何帮助，但正如你在问题中提出的那样，试试这个：

C＃： 

  protected   void  RadioButton_CheckedChanged（对象发​​件人，EventArgs e）
 {
 myTxt.Enabled =  true ; 
}



或使用jQuery：

（ ＃radioButton）。change（ function （）{


（ #myTxtBox）。removeAttr（ disabled）;
}） ;

解决方案

Posting this much code didn't get me anything, but as you have asked in your question, try this:
C#:

protected void RadioButton_CheckedChanged(object sender, EventArgs e)
{
    myTxt.Enabled = true;
}


or using jQuery:


("#radioButton").change(function() {

("#myTxtBox").removeAttr("disabled");
});
