# Handling Errors

## Content

**C1Input** supports handling data validation and formatting errors in data‑entry applications.
WinForms data sources such as **[ADO.NET](http://ADO.NET "http://ADO.NET")** and **C1DataObjects** detect logical data errors and report them through the **RowError** property or the **SetColumnError** method. These errors can be displayed in **C1Input** controls by using the **System.Windows.Forms.ErrorProvider** component.
The **ErrorProvider** component integrates with **C1Input** controls in the same manner as with standard WinForms controls.
