推荐答案

看起来你正在尝试分配一个选中或未选中的单选按钮。< br $> b $ b

Looks like you are trying to assign a Radio Button checked or not-checked.

//To set the text of the Radiobutton
StatusRadioButtonList.Text = "Selected value";

//Tot set checked or not
StatusRadioButtonList.Checked = true;

//If you are trying to check and set more than 1 Radio button
//All the radio button should of same group
if (rdoStatusRadioButtonListA.Text.ToString().Equals("One"))
        {
            rdoStatusRadioButtonListA.Checked = true;
        }
else  {
            rdoStatusRadioButtonListA.Checked = false;
            rdoStatusRadioButtonListB.Checked = true;
     }

如果这个答案没有解决您的问题，请告诉我。我将提供更详细的信息。

Let me know if this answer doesn't solve your problem. I will provide in much detail.

如果您从数据库中检索Active或Inactive值，您可以使用以下代码，

If you retrieving the Active or Inactive value from database you can use following code,

if(dr["RegionStatus"].ToString()=="Active")
{
   StatusRadioButtonList.Items[0].Selected=true;
   StatusRadioButtonList.Items[1].Selected=false;
}
else if(dr["RegionStatus"].ToString()=="Inactive")
{
   StatusRadioButtonList.Items[0].Selected=false;
   StatusRadioButtonList.Items[1].Selected=true;
}
