Dear All,

In my application i want to add validation in insert and Update for some fields. Please let me know how to add validations in the grid. Also I have found the following code in the internet which is not working for me.
<telerik:GridBoundColumn DataField="ShipName" HeaderText="ShipName" UniqueName="ShipName">
    <ColumnValidationSettings EnableRequiredFieldValidation="true" EnableModelErrorMessageValidation="true">
        <RequiredFieldValidator ForeColor="Red" ErrorMessage="This field is required"></RequiredFieldValidator>
        <ModelErrorMessage BackColor="Red" />
    </ColumnValidationSettings>
</telerik:GridBoundColumn>


In the above code snippet i am getting an error that the ColumnValidationSettings is not supported. Please help me.

Hi Shubhadeep,

You are getting such an error because your version of telerik doesn't support ColumnValidationSettings , please upgrade to the latest version, or try setting the validation from server side. Please go through this documentation on Validation .You can set ServerSide validation in ItemCreated event of the RadGrid as shown below.

C#:
if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem item = e.Item as GridEditableItem;
        GridTextBoxColumnEditor editor = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor("ColumnUniqueName");
        TableCell cell = (TableCell)editor.TextBoxControl.Parent;
 
        RequiredFieldValidator validator = new RequiredFieldValidator();
        editor.TextBoxControl.ID = "ID_for_validation";
        validator.ControlToValidate = editor.TextBoxControl.ID;
        validator.ErrorMessage = "*";
        cell.Controls.Add(validator);
    }


Have a look and let me know if any concern.

Thanks,
Princy
