How to retrieve the adynamically created textboxes and Checkboxes

Question

I am using System.Windows.Forms
I need to to dynamically create textbox and checkbox on clicking Add button.
Depending upon how many checkboxes are checked,the texboxes should be deleted (When Delete button is Pressed).
What I have done is I have dynamically created Textbox and checkboxes and stored in an array of control.
But at the time of deleting ,When i am iterating through the array ,Its not deleting the corresponding texbox(for which the checkbox is checked)
Here goes my code
public Control[] arrayOfControl()
{
for (int i = 0; i < 10; i++)
{
arr[i] = new Control();
}
return arr;
}
//For dynamically creation of textbox and checkbox
private void btnAdd_Click(object sender, EventArgs e)
{
newtxt = new TextBox();
newchkbox = new CheckBox();

newchkbox.Name = "chk" + i.ToString();
newtxt.Name = "txt" + i.ToString();
arr[i].Controls.Add(newchkbox);
arr[i].Controls.Add(newtxt);
newchkbox.Location = new System.Drawing.Point(230, 72 + Position);
newtxt.Location = new System.Drawing.Point(27, 72 + Position);
newtxt.Size = new System.Drawing.Size(187, 20);
this.btnAdd.Location = new System.Drawing.Point(27, 109 + Position);
this.btnRem.Location = new System.Drawing.Point(113, 109 + Position);
groupBox1.Controls.Add(newtxt);
groupBox1.Controls.Add(newchkbox);
Position += 30;
i++;

}

//For delete
private void btnRem_Click(object sender, EventArgs e)
{
for (int j = 0; j < i; j++)
{
if (arr[j].Contains(newchkbox))
{
if (newchkbox.Checked == true)
{
groupBox1.Controls.Remove(this.newtxt);

}
}

}}
But the remove button is not working,I am not able to delete the particular textboxes from which checkboxes are checked..How to achieve that?

Likely this is happening because you are iterrating the array from the front to the back in your delete try doing it in the reverse order as removing items in your current solution may cause you to miss entries. With your current solution I believe you will miss any checkboxes that are checked when they follow another checked checkbox. For instance say you have this array: arr[0].checked = false arr[1].checked = false arr[2].checked = true arr[3].checked = true arr[4].checked = false In this scenario with your current code what happens is that you remove arr[2] and move to arr[3] but arr[3] is really what originally was arr[4] because you removed an entry.
