# Data Errors

Learn about the ErrorProvider component in C1Input controls.

## Content



WinForms data sources such as ADO.NET and C1DataObjects contain provisions for detecting logical errors in data, by the data source itself or by the programmer, setting the **RowError** property or calling the **SetColumnError** method (**SetFieldError** in C1DataObjects). You can show logical row and column errors in **C1Input** using System.Windows.Form.ErrorProvider component.

To show logical column errors, use the ErrorProvider component with **C1Input** controls as you would use it with any other controls.

To show row error in [C1DbNavigator](/componentone/api/win/online-input/dotnet-framework-api/C1.Win.C1Input.4.8/C1.Win.C1Input.C1DbNavigator.html) control, set the [ErrorProvider](/componentone/api/win/online-input/dotnet-framework-api/C1.Win.C1Input.4.8/C1.Win.C1Input.C1DbNavigator.ErrorProvider.html) property to an ErrorProvider component. Then C1DbNavigator will display error icon with RowError ToolTip text when there is an error in current row.
