Hi All

I am trying to generated the dynamic labels depending on the checked checkboxes which are dynamically created.

My .Net frame is 3.5
Here is code for dynamic checkboxes

C#

System.Windows.Forms.CheckBox[] checkBox = new System.Windows.Forms.CheckBox[bran_count];

            for (int i = 0; i < bran_count; ++i)
            {
                checkBox[i] = new CheckBox();
                checkBox[i].Name = "radio" + Convert.ToString(i);
                checkBox[i].Text = ds2.Tables[0].Rows[i][2].ToString();
                
                checkBox[i].Location = new System.Drawing.Point(125 * i, 15);
                groupBox1.Controls.Add(checkBox[i]);
                checkBox[i].CheckStateChanged += new System.EventHandler(CheckBoxCheckedChanged);
                
            }
        }
        private void CheckBoxCheckedChanged(object sender, EventArgs e)
        {
            //MessageBox.Show();
        }

Any guidance is welcome, if possible give some code snippet.
Regards

Just to clarify ... are you wanting to do something in CheckBoxCheckedChanged but need to know which checkBox[i] has just been clicked?

}
}

Solution 2

This will fire regardless of which checkbox is clicked but shows you how to work out which one it was

C#

private void CheckBoxCheckedChanged(object sender, EventArgs e)
{
    CheckBox c = (CheckBox)sender;
    MessageBox.Show(c.Name);
}

... and will only fire for the checkbox that was just checked
