问题描述
首先，我在页面加载时禁用了文本框，单击单选按钮后我要启用它，并且必须将单选按钮的单击值存储在数据库中.
first i have disabled textbox on page load, after clicking on radiobutton i want enable it and have to store clicked value of radio button in database
推荐答案
禁用文本不是ispostback中的框，并在raidobutton中启用它，请检查更改事件，因为您必须将radiobutton的autopostback设置为true，我建议您将其放置在updatepanel中....
disable text box in not ispostback and enable it in raidobutton check change event for that u have to set autopostback true of radiobutton and i suggest u to put it in updatepanel....
public partial class RadioButton : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Enabled = false;
}
protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
TextBox1.Enabled = true;
TextBox1.Text = "I Am Male";
string value = RadioButton1.Text;
SqlConnection sqlconn = new SqlConnection("server=.\\sqlexpress;database=practice;integrated security=true;");
SqlCommand sqlcomm = new SqlCommand("insert into insertvalue(radiobtnvalue) values(@a)", sqlconn);
sqlconn.Open();
sqlcomm.Parameters.Add("@a", SqlDbType.VarChar, 10).Value = value.ToString();
sqlcomm.ExecuteNonQuery();
sqlconn.Close();
Response.Write("Value Saved");
}
}
