Can any one help me to get the values of selected radio button which are place inside the listview control in asp.net using c#

i try this code

RadioButton rb1 = (RadioButton)ListView1.FindControl("RadioButton1");

if (rb1.Checked == true)

{

Label1.Text = rbl1;

}

but is shows me the following error

Object reference not set to an instance of an object.

Know the answer? Post it — somebody with the same question will find it here.

It is the same account you read, post and publish with — and you will come straight back to this page.

Hey.
It is showing error because rb1 is null and you are trying to find out it's checked value in if condition. You need to do a loop and need to findout radio button.
Thanks.

Hi, You are not able to fooud your radiobutton control inside listview. That is the reason you are getting object reference null. You need to loop through listview and find radio button. https://www.aspsnippets.com/Articles/ASPNet-GridView-Radio-Button-Single-Selection---Select-only-one-RadioButton-from-Column.aspx
