ltrlDays.Text = (DateTime.Now - Convert.ToDateTime(ActualActionDate)).Days.ToString();

Thanks

Hi ramco

To fix the error and avoid the null reference exception, you should check if ActualActionDate has a value before performing the calculation. Here's an updated version of your code:
```
DateTime? ActualActionDate;

if (ActualActionDate.HasValue)
{
    ltrlDays.Text = (DateTime.Now - ActualActionDate.Value).Days.ToString();
}
else
{
    ltrlDays.Text = "ActualActionDate is null";
}
```

Assign a valid DateTime value to the ActualActionDate variable before using it in the calculation. Make sure to replace (...) with the code that assigns a valid DateTime value to ActualActionDate. Then, we check if ActualActionDate is not null (ActualActionDate != null), and if it's not null, we calculate the difference in days between the current date and ActualActionDate using the .Value property.
```
DateTime? ActualActionDate = ...; // Assign a valid DateTime value to ActualActionDate

if (ActualActionDate != null)
{
    int daysDifference = (DateTime.Now - ActualActionDate.Value).Days;
    ltrlDays.Text = daysDifference.ToString();
}
```
