Namespace: DevExpress.XtraVerticalGrid

Assembly: DevExpress.XtraVerticalGrid.v24.2.dll

Declaration

C#

public virtual void SetRowError(
    RowProperties props,
    string errorText
)

VB.NET

Public Overridable Sub SetRowError(
    props As RowProperties,
    errorText As String
)

Parameters

Name	Type	Description
props	RowProperties	A RowProperties object that identifies the target cell.
errorText	String	The error description. An empty string to clear the previously assigned error.

Remarks

Use the SetRowError method to assign errors to records or individual cells. This can be useful if you handle the VGridControlBase.ValidateRecord event to perform input validation and want to indicate input errors within cells.

The control shows an error icon when you assign an error to a cell. A user can hover over the icon to see a hint that displays the error description.

Set the errorText parameter to an empty string to clear the previously assigned error.

A call to the SetRowError method has no effect if no record is currently focused (the vertical grid’s VGridControlBase.FocusedRecord property’s value is -1).

See the following topic for information on how to handle errors at the data source level: Error Notification Support for Data Sources. The technique described in this topic allows you to set errors for any record, not only for the focused record.
