I am trying to create a Validation in a reusable fashion.

Purpose: Make the validation control reusable.

Error Provider should associate with control passed dynamically and can be set or cleared at run time.

When user press OnClick event then all the controls gets validated with their own Error Providers.

public bool IsFieldEmpty(ref TextBox txtControl, Boolean SetErrorProvider,string msgToShowOnError)
{
    ErrorProvider EP = new ErrorProvider();
    if (txtControl.Text == string.Empty)
    {
        if(SetErrorProvider==true)
            EP.SetError(txtControl, msgToShowOnError);
        return true;
    }
    else
    {
        if(SetErrorProvider==true)
            EP.Clear();
        return false;
    }
}

Issue:

Every time the function is called new errorprovider object gets created which i dont want. Every control should not have more than 1 error provider and i should be able to search it just like as done in asp.net to search for some control on a Page.

How can I do this
