Define Validation rules for SfDataGrid

Hi forum,

I would like to set validation rules for the entire data grid or a column.
Is there an example for this?

Hi Thomas, 
Thanks for using Syncfusion product. 
You can able to validate the data in a column by using DataAnnotation attributes by setting SfDataGrid.GridValidationMode or GridColumn.GridValidationMode property to InEdit or InView. 
Please refer the below code example, 
<syncfusion:SfDataGrid x:Name="grid" 
                       ItemsSource="{Binding UserDetails}"> 
[Range(10000, 30000, ErrorMessage = "The “Salary” field can range from 10000 through 30000.")] 
public int Salary 
    get { return salary; } 
    set { salary = value; OnPropertyChanged("Salary"); } 
You can also validate the cells and rows using CurrentCellValidating and RowValidating events in SfDataGrid. You can refer the below UG and KB links for your further details,

Hi Thomas,  
Thanks for your update. 
We have analyzed your query , We regret to inform you that currently we don’t have a support for “Applying validation rules in SfDataGrid”. We have already logged this requirement as feature request in our database. We don’t have any immediate plans to implement this feature. At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest.  We will implement this feature in any of our upcoming release. We will let you know when this feature is implemented. We appreciate your patience until then  
Please login to view the feedback further,  
Also as mentioned in our previous update, You can use custom validation using CurrentCellValidating and RowValidating events or you can use built in validation using IDataErrorInfo/InNotifyDataErrorInfo instead of ValidationRule.  
Please refer the below UG link for IDataErrorInfo.

I got it to work with the INotifyDataErrorInfo.
Thanks for your help.
