HtmlImage.Height Property
Gets or sets the height of the image.
[Visual Basic] Public Property Height As Integer [C#] public int Height {get; set;} [C++] public: __property int get_Height(); public: __property void set_Height(int); [JScript] public function get Height() : int; public function set Height(int);
Property Value
The height of the image.
Remarks
The Height and Width properties can be used two ways. You can use the Height and Width properties to send image size specifications to the browser. This displays the Web page faster because the browser does not need to recalculate the positions of elements on the page when the image loads.
You can also use the Height and Width properties to scale the image. When using values different from the physical size of the image, the image is resized accordingly. However, this method for scaling the image is not recommended because it takes longer for the page to display. Instead, physically resize the image to the size you need.
By default, the Height property is expressed in pixels, but it can also be expressed as a percentage of the size of the window.
Example
[Visual Basic, C#, JScript] The following example demonstrates how to use the Height property to programmatically modify the height of the displayed image.
[Visual Basic] <%@ Page Language="VB" AutoEventWireup="True" %> <html> <head> <script language="VB" runat="server"> Sub Button_Click1(sender As Object, e As EventArgs) Image1.Height = 500 Image1.Width = 1000 End Sub 'Button_Click1 Sub Button_Click2(sender As Object, e As EventArgs) Image1.Height = 226 Image1.Width = 500 End Sub 'Button_Click2 </script> </head> <body> <form runat="server"> <h3>HtmlImage Example</h3> <img id ="Image1" Src="image1.jpg" Width="500" Height="226" Alt="Image 1" Border="5" Align="center" runat=server/> <br><br> <button id="Button1" OnServerClick="Button_Click1" runat="server"> Zoom Image </button> <button id="Button2" OnServerClick="Button_Click2" runat="server"> Normal Size </button> </form> </body> </html> [C#] <%@ Page Language="C#" AutoEventWireup="True" %> <html> <head> <script language="C#" runat="server"> void Button_Click1(object sender, EventArgs e) { Image1.Height=500; Image1.Width=1000; } void Button_Click2(object sender, EventArgs e) { Image1.Height=226; Image1.Width=500; } </script> </head> <body> <form runat="server"> <h3>HtmlImage Example</h3> <img id ="Image1" Src="image1.jpg" Width="500" Height="226" Alt="Image 1" Border="5" Align="center" runat=server/> <br><br> <button id="Button1" OnServerClick="Button_Click1" runat="server"> Zoom Image </button> <button id="Button2" OnServerClick="Button_Click2" runat="server"> Normal Size </button> </form> </body> </html> [JScript] <%@ Page Language="JScript" AutoEventWireup="True" %> <html> <head> <script language="JSCRIPT" runat="server"> function Button_Click1(sender : Object, e : EventArgs){ Image1.Height = 500 Image1.Width = 1000 } function Button_Click2(sender : Object, e : EventArgs){ Image1.Height = 226 Image1.Width = 500 } </script> </head> <body> <form runat="server"> <h3>HtmlImage Example</h3> <img id ="Image1" Src="image1.jpg" Width="500" Height="226" Alt="Image 1" Border="5" Align="center" runat=server/> <br><br> <button id="Button1" OnServerClick="Button_Click1" runat="server"> Zoom Image </button> <button id="Button2" OnServerClick="Button_Click2" runat="server"> Normal Size </button> </form> </body> </html>
