Hi Mark,
The simplest way would be to check for null (or Nothing in VB), like this:
ListItem testItem =
drpPropertyType.Items.FindByValue(parameterProperty_Type_ID.Value.ToString());
if(testItem == null) {
// do it to it
}
Cheers,
Peter

All,
I am using the following C# code to find and select an item in a DDL based on
an output param from a sproc:
drpPropertyType.Items.FindByValue(parameterProperty_Type_ID.Value.ToString()).Selected
= true;
But I see that some values may not be present in my DDL that matches the value
in my output param and it generates an error:
System.NullReferenceException: Object reference not set to an instance of an
object.
When I change the param value to match a value that exists in my DDL, the error
goes away.
How can I check for the existing of the variable "parameterProperty_Type_ID" in
my DDL before I try to select it?
Thanks,
Mark
