Required field validation for GridEditorColumn

[Clive Hoggar]

Hi guys

I am staring at this but cannot see anything wrong. But it does not trigger validation when there is no text entered in the editor on Update. What am I missing?

Thanks

<telerik:GridHTMLEditorColumn DataField="BodyText" HeaderText="BodyText" SortExpression="BodyText" UniqueName="BodyText" ColumnEditorID="MyColumnEditor1">
 </telerik:GridHTMLEditorColumn>

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)
        If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then
            Dim item As GridEditableItem = CType(e.Item, GridEditableItem)
            Dim editor As GridTextBoxColumnEditor = CType(item.EditManager.GetColumnEditor("BodyText"), GridTextBoxColumnEditor)
            Dim cell As TableCell = CType(editor.TextBoxControl.Parent, TableCell)
            Dim validator As RequiredFieldValidator = New RequiredFieldValidator
            editor.TextBoxControl.ID = "MyColumnEditor1"
            validator.ControlToValidate = editor.TextBoxControl.ID
            validator.ErrorMessage = "Please enter some text!"
            cell.Controls.Add(validator)
        End If
    End Sub

Hi,

Please try the following code snippet to give validation for GridHTMLEditorColumn.

VB:

Protected Sub RadGrid1_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs)
    If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then
        Dim item As GridEditableItem = DirectCast(e.Item, GridEditableItem)
        Dim editor As GridHTMLEditorColumnEditor = DirectCast(item.EditManager.GetColumnEditor("BodyText"), GridHTMLEditorColumnEditor)
        Dim cell As TableCell = DirectCast(editor.Editor.Parent, TableCell)
        Dim validator As New RequiredFieldValidator()
        editor.Editor.ID = "MyColumnEditor1"
        validator.ControlToValidate = editor.Editor.ID
        validator.ErrorMessage = "Please enter some text!"
        cell.Controls.Add(validator)
    End If
End Sub

Thanks,
Shinu.

Hi

Thanks for quick reply

I did try this code, and there were no design time or run time errors, but it did not trigger the validation for the GridEditor Column.
In the same grid there are declarative validators for a text box and a combo box, which do fire as expected, so all seems to be OK ajax-wise.

I guess could revert to a template column and a radcombobox, but it seemed more elegant to use the special column provided.
Has anyone got the validation working for this column type?

Thanks

Clive

Hi Clive,

The purpose of the GridHTMLEditorColumn is to display HTML and not to validate controls. When editing the content of this column you are editing the HTML in the field. If you want to put controls in a column I suggest that you use GridTemplateColumn instead. By doing so you would be able to validate the controls inside.
