Access Textfield Name Using Variable (Dynamically)

I'm currently working on an Windows Phone 7 App

I have at least 9 Textfields with the name "TEXTFIELD_ID_1" , "TEXTFIELD_ID_2" etc... There will be more.

I want to access every of these fields with a loop:

if (currentpage == 1)
{
    for (int i = 1; i<10; i++)
    {
        string[] beitrag = result.Split(new string[] { "<split_inner>" }, StringSplitOptions.None);

        profile_img_1.Source = (ImageSource)new ImageSourceConverter().ConvertFromString("EXAMPLE.jpg);               
    }
}

As you can see I access Image one using the direct way (1). How can I use my variable "i" to access the image / textfield ?

Thx

If names are regular like that then just use:

string name = "TEXTFIELD_ID_" + i;
this.Controls[name].Text = "bla bla bla...";

The key point is the ControlCollection. this refers to your Form.You can access a Form Control with it's name or index.

Edit: In WP7 you must have a container like a Grid. For example if you have a grid control named LayoutRoot, you can access your elements with Children property.If you want loop through your TextBoxes you can use OfType extension method:

var elements = LayoutRoot.Children;

foreach (var element in elements.OfType<TextBox>())
{
     var currentTextBox = element as TextBox;
     ...
}

You can use FindControl method in your loop:

if (currentpage == 1)
{
    for(int i = 1; i<10; i++)
    {
        string[] beitrag = result.Split(new string[] { "<split_inner>" }, StringSplitOptions.None);
        Control imgControl = FindControl(string.Format("profile_img_{0}", i));
        imgControl.Source = (ImageSource)new ImageSourceConverter()
                                 .ConvertFromString("EXAMPLE.jpg);
    }
}
