- Q You create an ASP.NET server control to display date and time information. You want to enable other programmers who use your control to customize the style properties of a Label control named timeTKLabel. The timeTKLabel control displays the date and time. You create two custom property procedures to accomplish this goal. One procedure modified the BackColor property of the constituent controls. The other procedure modifies the ForeColor property of the constituent controls. In addition to these two custom property procedures, you want to allow users to apply one of two predefined styles. The predefines styles are created in the following function: public Style GetStyle(int styleType) { Style myStyle = new Style(); switch (styleType) { case 1: myStyle.ForeColor = System.Drawing.Color.White; myStyle.BackColor = System.Drawing.Color.Black; break; } return myStyle; } You want to write a public method that will apply these styles. You do not want to overwrite the ForeColor property and BackColor property if the Label control of these properties are already set by using the custom property procedures. Which code segment should you use for this method? A. public void PickStyle(int styleType) { Style myStyle = GetStyle(styleType); timeTKLabel.ApplyStyle(myStyle); } B. public void PickStyle(int styleType) { Style myStyle = GetStyle(styleType); timeTKLabel.MergeStyle(myStyle); } C. public void PickStyle(int styleType) { Style myStyle = GetStyle(styleType); timeTKLabel.ForeColor = myStyle.ForeColor; timeTKLabel.BackColor = myStyle.BackColor: } D. public void PickStyle(int styleType) { Style myStyle = GetStyle(styleType); timeTKLabel.CssClass = myStyle.CssClass; }
