Question

Windows窗体上未选中已选中的单选按钮。

我已经用一个消息框对其进行了测试，并且其书面内容已选中...

您可以要求更多代码/信息。 语言是法语。

新图片：根据我的sql数据库，控制台输出正确。

// LOAD RADIOBUTTON
                SQLCommand.CommandText = ChargementRadiobuttonCommandText;
                reader = SQLCommand.ExecuteReader();

Answer 1

您是否尝试过以下代码？

this.Update();

要么

this.Refresh();

使用Form类中的某些方法执行此操作以更新您的表单。

我已解决此问题： reponseGroupBox[iterationQuestion].Controls.OfType<RadioButton>()似乎更有效。

foreach (string ReponseRadioButton in ReponsesRadioButton)
                {
                    foreach (RadioButton radioButtonActuel in reponseGroupBox[iterationQuestion].Controls.OfType<RadioButton>()) // Pour chaque RadioButton du reponseGroupBox associé à questionActuel
                    {
                            if (radioButtonActuel.Text == "En accord" && ReponseRadioButton == "En accord")
                            {
                                radioButtonActuel.Checked = true;
                            }

                            if (radioButtonActuel.Text == "En desaccord" && ReponseRadioButton == "En desaccord")
                            {
                                radioButtonActuel.Checked = true;
                            }

                            if (radioButtonActuel.Text == "Non applicable" && ReponseRadioButton == "Non applicable")
                            {
                                radioButtonActuel.Checked = true;
                            }
                    }
                    iterationQuestion++;
                }
