To have multiple groups of radio buttons that should not affect each other, it is necessary to group them as a GroupBox or Panel.
In Visual Studio, open your toolbox, scroll down to “Containers” and choose your box / panel. All radio buttons in this box / panel will now be interconnected.
This loop function will clear all TextBoxes in your Form, wherever they are placed.
Comes in handy when creating a “Clear fields” button
private void button1_Click(object sender, EventArgs e)
private void RecursiveClearTextBoxes(Control.ControlCollection cc)
foreach (Control ctrl in cc)
TextBox tb = ctrl as TextBox;
if (tb != null)
I suddenly got this error in my ASP.NET Web Forms project in Visual Studio. Even after creating a new Web Form without content, I was thrown this error. The solution was very simple. All you have to do is rebuild your project.
