How to: Supply Custom Error Icon for Editor
The following example shows how to supply a custom error icon via the DXErrorProvider.GetErrorIcon event. In this event, a custom icon (
) is provided when the error type is set to ErrorType.User1.
The result is illustrated below:
using DevExpress.XtraEditors.DXErrorProvider;
DXErrorProvider.GetErrorIcon += new GetErrorIconEventHandler(DXErrorProvider_GetErrorIcon);
// Associate an error of the User1 error type with a buttonEdit1 control.
dxErrorProvider1.SetError(buttonEdit1, "Error", ErrorType.User1);
//...
Image icon = Image.FromFile(@"C:\arrow.png");
// Provide an error icon for the User1 error type.
void DXErrorProvider_GetErrorIcon(GetErrorIconEventArgs e) {
if (e.ErrorType == ErrorType.User1) {
e.ErrorIcon = icon;
}
}
