Accessing a dynamic RadioButtonList array object

Question

0.00/5 (No votes)

See more:

I've created an array of RadioButtonList class, but apparently can't seem to access it or use the answer retrieved from it.

I always get the exception: Object reference not set to an instance of an object.

protected void Button5_Click(object sender, EventArgs e)
{


    RadioButtonList[] RBLPain = new RadioButtonList[2];





        RBLPain[0] = new RadioButtonList();


        RBLPain[0].Items.Add("Yes");

        RBLPain[0].Items.Add("No");

        Panel1.Controls.Add(RBLPain[0]);



            if (RBLPain[0].SelectedItem.Text == "Yes")
            {
               Response.Write(RBLPain[0].SelectedItem.Text);
            }


    }

Any help would be appreciated thanks :)

Solution 1

you can alter your code like this , add a judgment :

C#

ifRBLPain[0].SelectedItem != null)
{
  if (RBLPain[0].SelectedItem.Text == "Yes")
   {
       Response.Write(RBLPain[0].SelectedItem.Text);
   }
}

if you have a doubt else, let me know.

lad, this would obviously work since the condition never meets! the selected item will always be null, and hence the condition will be skipped through! what i want is to go inside the if condition

oh,i see.you can specify a option,like this :

RadioButtonList[] RBLPain = new RadioButtonList[2];
RBLPain[0] = new RadioButtonList();
RBLPain[0].Items.Add("Yes");
RBLPain[0].Items.Add("No");
RBLPain[0].Items[0].Selected = true;
Panel1.Controls.Add(RBLPain[0]);
if (RBLPain[0].SelectedItem.Text == "Yes")
{
Response.Write(RBLPain[0].SelectedItem.Text);
}
