Binding Array string to a textblock

Aslesh

Hi, Can we bind array of strings to a Textbloxk?

Brian Griggs

Yes. Do you want the text to be just one item in the array, or all of them seperated by a comma or something?

Aslesh

If you have the answer for both of them that will be gr8 or else either of the one is fine

Brian Griggs

For a single item you can specify the index in the binding (StrArray would be the string array in your data class):

Text="{Binding Path=StrArray[0]}"

The trick to get all the values in a string seperated by commas is to use a value converter - something like this:

public class StrArrayConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
string[] strArr = value as string[];
if (strArr != null)
{
StringBuilder sb = new StringBuilder();
foreach (string s in strArr)
{
sb.Append(s);
sb.Append(", ");
}
return sb.ToString();
}

    return null;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
    return null;
}

}
