How do I enumerate the controls on a form and take action when I have found the one I want?

Question

What I want to do is this :-

for (int i = 0; i < Grid1.Children.Count; i++)
     {
     if (current control's name is 'imageX')
            {
             do something
             i = Grid1.Children.Count;
            }
    }

but I am unable to work out how to accomplish this.

Hi,
Here you are checking for the name of the control.In this case you should add a name to the control when you are adding to the grid.

 <Grid Name="Grid1">
        <Button Name="Button1" Height="35" VerticalAlignment="Top" Margin="0,0,65,0" />
        <CheckBox Height="16" Margin="53,86,105,0" Name="checkBox1" VerticalAlignment="Top">CheckBox</CheckBox>
        <ComboBox Height="23" Margin="59,0,99,74" Name="comboBox1" VerticalAlignment="Bottom" />
    </Grid>

Here i have added some elements to the grid.

 foreach (FrameworkElement  objelement in Grid1.Children)
            {
                if (objelement.Name == "comboBox1")
                {
                    MessageBox.Show("Combo Found");  
                }
            }

Actually in this case what are you trying to do?

Hope it helps
