Could not create and fill the business object of type 'STI.InventoryBO'. [/quote]<br> <br> I setup everything correctly, i think, not sure why I'm getting this error.<br> <br> Any ideas?Wed, 26 Jul 2006 15:03:06 GMTStarkMikehttp://forum.strataframe.net/FindPost1957.aspxThat's what we're here for! ;)Wed, 26 Jul 2006 15:03:06 GMTTrent L. Taylorhttp://forum.strataframe.net/FindPost1955.aspxThaks for the tip! I can ALWAYS use those!Wed, 26 Jul 2006 15:01:14 GMTStarkMikehttp://forum.strataframe.net/FindPost1953.aspxIt has to do with strong-typing.&nbsp; Your method has a parameter defined as a System.Int32.&nbsp; Any controls "Text" property is defined as a System.String.&nbsp; By passing just the Control.Text, you are passing a string typed value and the method expects integer.&nbsp; When you added the CInt(), it converted the text to Integer as the method was expecting.&nbsp; .NET is a strong-typed development environment.&nbsp; You cannot rely on automatic data conversions like other languages such as Visual FoxPro.&nbsp; This is actually a VERY good thing.&nbsp; You learn about type conversions either a compile time or very quickly when an app is run.&nbsp; So most of the "Data Type Mistmatch" error from the old days are gone.<P>Just FYI, I would not use CInt().&nbsp; It is very slow and is an obselete method.&nbsp; You should do most of your type conversions like this:</P><P>CType(Control.Text, System.Integer)Wed, 26 Jul 2006 14:59:26 GMTTrent L. Taylorhttp://forum.strataframe.net/FindPost1952.aspxI did that. I fixed it. Not sure why this works. I'm sure you can explain it to me. :P<br> <br> This is what I had when it wasnt working...<br> [code]e.Parameters(0).Value = Me.txtPOID.Text[/code]<br> <br> I changed it to this and it worked.<br> [code]e.Parameters(0).Value = Cint(Me.txtPOID.Text)[/code]<br> <br> Can you enlighten me as to why that conversion made a difference?<br>Wed, 26 Jul 2006 14:55:14 GMTStarkMikehttp://forum.strataframe.net/FindPost1951.aspxDoes the method you selected require parameters?&nbsp; If so you need to set those parameters in the ListPopulating event of the list.&nbsp; There will be an event argument like this:</P><P>e.Parameters(0).Value = 1<BR>e.Parameters(1).Value = "Second Parm"Wed, 26 Jul 2006 14:51:49 GMTTrent L.
