根据组合框值启用或禁用文本框 [英] Enable or disable textbox based on combobox value

问题描述

if (comboBox2.SelectedItem.ToString() == "Yes")
{
    textBox1.IsEnabled = false;
    textBox1.Text = "Good Health";
}
else
{
    textBox1.IsEnabled = true;
}

i试过这个并且还使用了comboBox2.selectedvalue.equals（是 ）但结果仍然相同。

i have tried this and also used comboBox2.selectedvalue.equals("Yes") but the result is still the same.

推荐答案

这里试试这个：

Here try this:

if (comboBox2.SelectedItem.ToString() == "Yes")
{
    textBox1.Enabled = false;
    textBox1.Text = "Good Health";
}
else
{
    textBox1.Enabled = true;
}

试试这样，

Try like this,

if (comboBox2.SelectedItem.ToString() == "Yes")
{
    textBox1.IsEnabled  Enabled = false;
    textBox1.Text = "Good Health";
}
else
{
    textBox1.IsEnabled  Enabled  = true;
}
