| KaxInputControlMaxLength Property |
Gets or sets the maximum number of characters allowed in the text box.
Namespace: Kettic.AspNet.Controls
Assembly: Kettic.AspNet.Controls (in Kettic.AspNet.Controls.dll) Version: 2014.4.1129.0 (2014.04.1129.0)
SyntaxProperty Value
Type: Int32The maximum number of characters allowed in the text box. The default is 0, which indicates that the property is not set.
Remarks
Use the MaxLength property to limit the number of characters that can be entered
in the KaxInput control. This property cannot be set by themes or style sheet
themes. For more information, see ThemeableAttribute and Introduction to ASP.NET
Themes.
ExamplesThe following code example demonstrates how to use the MaxLength property to limit the number of characters allowed in the KaxTextBox control to 3. This example has a KaxTextBox that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements.
