+## Description
+
+I want to prevent the tooltip of the [RadDateTimePicker](https://docs.telerik.com/devtools/wpf/controls/raddatetimepicker/overview) control from showing when its content is set to Error.
+
+## Solution
+
+To achieve this behavior, subscribe to the `ParseDateTimeValue` event of the RadDateTimePicker control. Check the `IsParsingSuccessful` property of the event arguments, and if it is false, set the `IsTooltipOpen` property of the control to false. Use the `Dispatcher.BeginInvoke` method to delay this logic.
+
+Follow these steps:
+
+1. Subscribe to the `ParseDateTimeValue` event of RadDateTimePicker.
+2. Implement the logic to check `IsParsingSuccessful` in the event handler.
+3. If `IsParsingSuccessful` is false, use `Dispatcher.BeginInvoke` to set `IsTooltipOpen` to false.
+
+Example implementation:
+
+```csharp
+    private void RadDateTimePicker_ParseDateTimeValue(object sender, ParseDateTimeEventArgs args)
+    {
+        if (!args.IsParsingSuccessful)
+        {
+            Dispatcher.BeginInvoke(new Action(() =>
+            {
+                this.dateTimePicker.IsTooltipOpen = false;
+            }));
+        }
+    }
+```
+
+Attach the event handler to your RadDateTimePicker instance:
+
+```csharp
+    this.dateTimePicker.ParseDateTimeValue += RadDateTimePicker_ParseDateTimeValue;
+```
+
+This approach prevents the tooltip from displaying when parsing the input fails.
