Hi, I'm using a RadDataFilter to filter data on a RaGridView.
For datetime columns I've noticed some problems.
First, in the control the date is displayed in english format (see first attached image). When I try to change the value a datetimepicker appears and in this case the date is in italian format (according to my pc settings).
Second, I've noticed when the radDataFilter.Expression is generated the date is in english format, including time, and it is inside a couple of #, i.e the expression generated is like:
[myDate] >= #11/20/2023 14:55:07#
I would like to have only the date without time, is it possible?
And how can manage this expression to generate the SQL expression, cause the # is not accepted.
Thank you in advance for any help.

Hello, Giovanni,
Thank you for the provided pictures.
If you want to customize the text while the detetimepicker is not in edit mode, you can use the DataFilter.NodeFormatting event and change the text of the value element according to your needs. Additional information how to handle this event is available here: Formatting Nodes - RadDataFilter - Telerik UI for WinForms
Please refer to the following code snippet which sets new format to the value element:
private void DataFilter_NodeFormatting(object sender, TreeNodeFormattingEventArgs e)
{
DataFilterCriteriaElement criteriaNode = e.NodeElement as DataFilterCriteriaElement;
if (criteriaNode != null)
{
DataFilterCriteriaNode node = criteriaNode.Data as DataFilterCriteriaNode;
criteriaNode.ValueElement.Text = ((DateTime?)node.DescriptorValue).Value.ToString("dd/MM/yyyy");
}
}
As to your second and third questions, they have already been answered in the other thread that you have opened. Please see my reply there.
