ErrorText Property (InputComponent)

In This Topic

Gets or sets an error description string with optional HTML tags.

Syntax

Visual Basic
C#

'Declaration
 
Public Overridable Property ErrorText As String

public virtual string ErrorText {get; set;}

Remarks

Setting this property to a non-empty string causes the component to be highlighted. The message is displayed as a tooltip when the user moves the mouse over the component.

Setting this property to an empty string removes the higlight and restores the original tooltip text (ToolTipText).

Example

The example below uses the Validating event to set the error property on an InputNumericBox when the value entered is not an even number.

private void inputNumericBox1_Validating(object sender, CancelEventArgs e)
{
    if (inputNumericBox1.Value % 2 != 0)
    {
        inputNumericBox1.ErrorText = 
            "Please enter an <b>even</b> number!";
        e.Cancel = true;
    }
    else
    {
        inputNumericBox1.ErrorText = string.Empty;
    }
}
