Update GridView of ASP.net Project

No error message at all, it just doesn't update the grid row

Here is my update command as can be seen in the above Sqldatasource:

UpdateCommand="UPDATE dbo.deploymentInfo
SET 
DeploymentSiteRoot = @DeploymentSiteRoot,
dbservername = dbservername,
MSAccessServiceAccount = @MSAccessServiceAccount,
MSExcelServiceAccount = @MSExcelServiceAccount,
MSPPointServiceAccount = @MSPPointServiceAccount,
MSVisioServiceAccount = @MSVisioServiceAccount,
MSWordServiceAccount = @MSWordServiceAccount,
MSRootWebServiceAccount = @MSRootWebServiceAccount,
TimeofCreation = @TimeofCreation,
UpdateTime = GETDATE()
WHERE
DeploymentId = @DeploymentId">

Select allOpen in new window

Yes, the user is an admin and has update permissions.  I am using SQL Server 2008 R2 and Visual Studio 2010

Here is the code that I do have...

<asp:SqlDataSource ID="sqldataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:FileLibraryConnection %>" 
    DeleteCommand="spDeleteDeploymentInfoById" DeleteCommandType="StoredProcedure" 
    InsertCommand="spInsertDeploymentInfo" InsertCommandType="StoredProcedure" 
    SelectCommand="spGetAllDeploymentInfo" SelectCommandType="StoredProcedure"

Negative, I'm still where I left off.  The update query works but for some reason, the parameters are not matching up the text box field names to the sql parameters.  I ran an example and as opposed to having @dbservername, I typed in 'test'.  'test' was inserted into that field and the data was updated just fine.  So, how do I get it so that my update query reads the gridview textboxes like it is supposed to?

I'll still give points or effort, but the answer is what I stated above.

My answer was the overall correct answer.  All other explanations were good explanations and keypoints for other users, but I was the only one to find the correct resolution.
