If you now rebuild the ComboBoxEx control and run the demo application (or just run the complete project in the companion code), you ll see that the SelectedIndex prop erty is correctly preserved between postbacks and that the ComboBoxEx control works as expected. You might have noticed that the RaisePostDataChangedEvent method of the IPostBackDataHandler interface is left empty. The purpose of this method will become clear in the next section. The ComboBoxEx control still lacks a SelectedIndexChanged event. You already know how to declare an event in a class: qr code reader c# .net VB .

PDF417 Barcode Encoder Class Library and Demo App Ver. 2.1. Now that you have a score value to display you need some code to write it on the screen so that the player can see it increasing. The best way to do this is to create a general-purpose method for drawing text. You can then use the method to draw text whenever you need to display a message. The method needs to be given the text to be displayed, the position of the text, and the color of the text. It uses a font resource that is loaded by LoadContent and draws using the spriteBatch that is set up by the game: Event SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) 3 net qr code reader open source Packages matching Tags:"QR" - NuGet Gallery

The next step is to raise the event when the SelectedIndex property changes. You might be tempted to do this from inside the Set block in the SelectedIndex property procedure or from the LoadPostData event if you detect that a new value is being assigned to the SelectedIndex property. However, as I explained in the Raising Events in the Page section earlier in this chapter, this technique can create subtle bugs because the client page can receive the event before all controls on the page have been completely updated after the postback. For example, the code in the event han dler might use the SelectedIndex property of another ComboBoxEx control and would get the wrong value if that control hadn t processed its own LoadPostData method yet. 28: DropDownList control, the onchange attribute causes the __doPostBack routine to run. This routine loads the control name into the __EVENTTARGET field, loads the second argument (a null string in this case) in the __EVENTARGUMENT field, and submits the form via code. When the request gets to the server, the ASP.NET infrastructure can check the value of the __EVENTTARGET field and, if the field isn t empty, ASP.NET can determine which control caused the postback. Of all the additional elements on the page the hidden fields, the JavaScript routine, and the attribute in the HTML tag you only have to care about the onchange attribute in the <select> tag. ASP.NET adds the hidden fields and the JavaScript routine automatically if it recognizes that one or more controls on the form rely on the AutoPostBack feature. The only necessary condition for this to happen is that you use the Page.GetPostBackEventReference method when you build the HTML attribute, as I ll explain in a moment. Let s start by correctly implementing the AutoPostBack property. This step is simple because this code does nothing but save and restore the value of the property from the ViewState collection: The AutoPostBack property Property AutoPostBack() As Boolean Get Dim objValue As Object = Me.ViewState( AutoPostBack ) If objValue Is Nothing Then Return False Else Return CBool(objValue) End If End Get Set(ByVal Value As Boolean) Me.ViewState( AutoPostBack ) = Value End Set End Property void drawText(string text, Color textColor, float x, float y) { int layer; Vector2 textVector = new Vector2(x, y); // Draw the shadow Color backColor = new Color(0, 0, 0, 20); for (layer = 0; layer < 10; layer++) { spriteBatch.DrawString(font, text, textVector, backColor); textVector.X++; textVector.Y++; } // Draw the solid part of the characters backColor = new Color(190, 190, 190); for (layer = 0; layer < 5; layer++) { spriteBatch.DrawString(font, text, textVector, backColor); textVector.X++; textVector.Y++; } // Draw the top of the characters spriteBatch.DrawString(font, text, textVector, textColor); } free qr code reader for .net QR Code Encoder and Decoder .
