Select and Edit don't work in GridView.

I have a Gridview on an ASP.Net page with several other GVs.  The others work fine, but one of them has suddenly decided that it doesn't want to let me select or edit a row.  This GV is like a "detail" of the selected row of the GV above it, but that's not important.  The one above it works fine.  I select a row and then this one gets populated with the associated data which may be several rows.  But, when I click Select or Edit, nothing happens.  If I click Delete, the row is deleted.

What could I be missing?

I thought that perhaps this SELECT query in SqlDataSource3 was causing a problem (I don't know):
SELECT   keyJobTitleID,
         JobTitle,
         ISNULL(cbWeekdays,'False')                AS cbWeekdays,
         ISNULL(cbSaturdays,'False')               AS cbSaturdays,
         ISNULL(cbSundays,'False')                 AS cbSundays,
         ddlBackgroundCheck,
         JobDescription,
         ddlStartTime,
         ddlEndTime,
         ISNULL(cbMonday,'False')                  AS cbMonday,
         ISNULL(cbTuesday,'False')                 AS cbTuesday,

         ISNULL(cbCollegeDegree,'False')           AS cbCollegeDegree,

         ISNULL(cbMSWord,'False')                  AS cbMSWord,
         ISNULL(cbMSExcel,'False')                 AS cbMSExcel,
         ISNULL(cbMSPowerPoint,'False')            AS cbMSPowerPoint,

         radPotentialEmployment,
         radInterviewCandidate,
         txtRequestedSkills
FROM     JobTitles
WHERE    (keyWorksiteID = @keyWorksiteID)
ORDER BY keyJobTitleID

So I tried changing it to:
SELECT *
FROM     JobTitles
WHERE    (keyWorksiteID = @keyWorksiteID)
ORDER BY keyJobTitleID

Of course that didn't make any difference.  It had been working just fine before.

"But, when I click Select or Edit, nothing happens"
If you got those buttons, the problem should not be with the gridview itself... or maybe with one of your edit template??? Do you use ajax or something?
I suspect you get an error when you hit those buttons. (check at the lower left of IE)
You could alsy try to remove those columns one by one until it work.

Yeah, the error says "RadioButtonList has a SelectedValue which is invalid because it does not exist in the list of items."  That RadioButtonList is in a TemplateField of the GridView:

                  <asp:TemplateField HeaderText="Interview Candidate" SortExpression="radInterviewCandidate">
                        <EditItemTemplate>
                              <asp:RadioButtonList ID="radInterviewCandidate" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow" SelectedValue='<%# Bind("radInterviewCandidate") %>'>
                      <asp:ListItem>Yes</asp:ListItem>
                      <asp:ListItem>No</asp:ListItem>
                      <asp:ListItem>Call me to discuss</asp:ListItem>
                              </asp:RadioButtonList>
                        </EditItemTemplate>
                        <ItemTemplate>
                              <asp:Label ID="radInterviewCandidate" runat="server" Text='<%# Eval("radInterviewCandidate") %>'></asp:Label>
                        </ItemTemplate>
                  </asp:TemplateField>


I'm Googling for solutions to this problem but I'm finding all sorts of things and I can't make heads or tails of half of them.

One suggested adding a hidden ListItem:
                              <asp:ListItem Value="" Text="" style="display:none" />

That didn't solve my problem.  On some rows I do not get the error and on some I do.  I've tried looking in the database for clues but can not find a pattern.  I have 6 records that I can edit without the error and 4 that give me the error and no edit.  Both sets are a mix of selected items.  ?

David RobitailleAnalyst ProgrammerCommented:
ok, that should be easy to fix.
what is the content of : "radInterviewCandidate" it mutch match the conetnt of the value of the list item, specialy the one that gives error (SelectedValue='<%# Bind("radInterviewCandidate") try to find in within the options... )
ex
   <asp:ListItem Value="Yes" Text="Yes" />  
<asp:ListItem Value="No" Text="No"  />

  <asp:ListItem Value="Call" Text="Call me to discuss" />

Veeam Task Manager for Hyper-V

Task Manager for Hyper-V provides critical information that allows you to monitor Hyper-V performance by displaying real-time views of CPU and memory at the individual VM-level, so you can quickly identify which VMs are using host resources.

Okay, I changed all the values in the database for "radInterviewCandidate" to "No" just to get past that.  That worked and revealed the same issue with a DropDown box that contains values like this with dashes:
<asp:ListItem Value="Office - Data Entry" Text="Office - Data Entry" />
<asp:ListItem Value="Office - Receptionist" Text="Office - Receptionist" />
<asp:ListItem Value="Office - Customer Service" Text="Office - Customer Service" />
<asp:ListItem Value="Office - Multi-functional Admin" Text="Office - Multi-functional Admin" />
<asp:ListItem Value="Warehouse" Text="Warehouse" />

I copied the values from the code page into the database and notice that the dashes were different.  They became longer in the database field than the original values in the database field.

I can now edit all the rows in my GridView, but I'm still getting the error on page about an Invalid value in the SelectedValue.

David RobitailleAnalyst ProgrammerCommented:
To be able to Bind the SelectedValue, what is in the value property of the ListItem must be equal to the content of the database field, period.
If you whant to go futher, you could use "code" to translate a value to a text : ex  1 ="Office - Data Entry". Put those in a  table and link them, DropDownLists could be binded to a table (using another datasource). It a part of database normalization process.

Yeah, I copied the values from the ListItems to the database so that there was a DB field populated with each of the ListItems, including the "Select One..." item, yet I'm still getting the error.  I think I'll remove the dashes completely to eliminate that issue.  ...

David RobitailleAnalyst ProgrammerCommented:
ok, should work,i will wait for news on that.

megninAuthor Commented:
Those d@mn dashes!  That seems to have been the problem.  One of the Items had two dashes, "Office - Multi-functional Admin" and I missed the second dash the first time through.  
It all seems to be working okay now.  

Is there a comprehensive turorial on GridViews that includes all the pitfalls, "gotchas" and quirks to wach out for?  I use them so much and I ALWAYS have problems.
