Dim drCode7 As DataSet = LogData.StermQ3(properdate)

dgAvailable2.DataSource = drCode7.Tables(0).DefaultView
dgAvailable2.DataBind()

End If

dd1.DataSource = LogData.StermQ3(datelistquery).Tables(0).DefaultView
dd1.DataBind()
dd1.Items.Insert(0, new listitem("Any location", "%"))

And the error CommandText has not been initialized keeps showing up on the IIS event viewer log

I can't replicate the problem myself but I know it is happening can anyone suggest anything

The error says it happens with this line dd1.DataSource = LogData.StermQ3(datelistquery).Tables(0).DefaultView

Thanks

I think you are in a situation where none of the following conditions are met:

Session("TenHolStDateHP1") = "%"
Session("TenHolStDateHP1") = ""
Session("holidayduration") = "3/4" 
Session("holidayduration") = "14"
Session("holidayduration") = "7" 

Since you don't initialize datelistquery to anything and you end in an else if it seems possible that you are not assigning a query to this string and could pass an empty string to your StermQ3 function.

You may want to add an else statement to the end of your chain of if/else if statements as a catchall. What you would set datelistquery to in the else statement depends on what you are doing.
