I am trying to bind a document library list to SPGridview.
I saw an example found at this site: http://nishantrana.wordpress.com/2009/03/23/using-spgridview-to-bound-to-list-data-in-sharepoint/ 

But I get an error and a warning:
Error      1      The name 'grdPropertyValues' does not exist in the current context      C:\Users\sogunroI\Documents\Visual Studio 2008\Projects\HotLineWP\HotLineWP\hotline\HotLineIncoming.ascx.cs      32      40      HotLineWP

Warning      2      Type of 'HotLineDocs.HotLineIncoming.SPGridView1' is not CLS-compliant      C:\Users\sogunroI\Documents\Visual Studio 2008\Projects\HotLineWP\HotLineWP\hotline\HotLineIncoming.ascx.designer.cs      23      71      HotLineWP


Please help. Thanks!

SharePointGirl,

The code you gave, "SPGridView grdPropertyValues;" fixed the error but now I get a warning.
I should have given more details.  
The code you see above is a user control that will be in a web part.

I get the following warning now:
Warning      3      Field 'HotLineDocs.HotLineIncoming.grdPropertyValues' is never assigned to, and will always have its default value null      C:\Users\sogunroI\Documents\Visual Studio 2008\Projects\HotLineWP\HotLineWP\hotline\HotLineIncoming.ascx.cs      24      20      HotLineWP


The webpart code is below.
I tried to add the following in my "CreateChildControls()" but it does not recognize grdPropertyValues

grdPropertyValues = new SPGridView();
     Controls.Add(grdPropertyValues);

Any ideas?

Also, if this could have been done better, please enlighten me.  This is my first attempt at this.
Thanks for any help you can provide.
