ASP.NET UpdateCommand replace E_UID with U_UID - sql

I know this is simply a SQL question but I can't remember in ASP.NET how to make this work, keep getting UID column not there error.
want to get the value of UsersDataTbl.UID and UPDATE EnrollmentsTbl.UID

Why isn't my GridView updating?

I'm trying to update the 'question' field when I hit the 'update' button for a specific row. I am able to change the text when I hit the 'edit' button, but when I hit the 'update' button it reverts back to its original value. Nothing is changed in the database either.
Here is my markup:
<div class="divGrid" style="margin: 0 auto; width: 70%;">
<asp:GridView ID="QuestionsGridView" CssClass="gridView" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" Width="100%" CellPadding="4" ForeColor="#333333">

And the table:
SQLServer Table
EDIT:
After looking, in my EditItemTemplate, I bind the question to the textbox. Is it possible that after I click the update button that the original question is databound to the textbox again before it tries to update? If this is the case, how would I get around that?

After looking further into it, I realized I had forgotten the apparently very important "DataKeyNames" attribute in my GridView tag. I feel really dumb. Here is the new working code.

How to find average of two gridviews in sql vb.net

I have two GridView1 and GridView2 which give a numerical values I want to create another Gridview3 or functionality that can generate the average of both the values of the existing Gridview1 & GridView2 i.e. GridView3=(GridView1+GridView2)/2
How should I write the SQL statement for it.
This is my GridView code in aspx
<asp:GridView ID="GridView7" runat="server" AutoGenerateColumns="False" BackColor="LightGoldenrodYellow" BorderColor="Tan" BorderWidth="1px" CellPadding="2" DataSourceID="SqlDataSource9" ForeColor="Black" GridLines="None">
<AlternatingRowStyle BackColor="PaleGoldenrod" />
<Columns>
<asp:BoundField DataField="mean_POLQA_score" HeaderText="mean_POLQA_score" ReadOnly="True" SortExpression="mean_POLQA_score" />
</Columns>
<FooterStyle BackColor="Tan" />
<HeaderStyle BackColor="Tan" Font-Bold="True" />
<PagerStyle BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" />
<SortedAscendingCellStyle BackColor="#FAFAE7" />
<SortedAscendingHeaderStyle BackColor="#DAC09E" />
<SortedDescendingCellStyle BackColor="#E1DB9C" />
<SortedDescendingHeaderStyle BackColor="#C2A47B" />
</asp:GridView>
The SQL queries are as follows
SELECT ROUND(AVG(POLQA_Score),3) AS mean_POLQA_score FROM VQTPOLQA WHERE VQT_Timestamp BETWEEN ? AND ? AND VQuad_PhoneID =?
SELECT ROUND(AVG(POLQA_Score),3) AS mean_POLQA_score1 FROM VQTPOLQA WHERE VQT_Timestamp BETWEEN ? AND ? AND VQuad_PhoneID =?

No value given for one or more required parameters. System.Data.OleDb.OleDbException:

After editing the SQL DATA source that is attached to the particular GridView we can modify the ? content to be Control TextBox and DropDown by using the ideal SQL query this solves the issue.

Updating SQL database using gridview/templatefield

Anybody know how to get a Templatefield column of text-boxes to feed data typed into them back into a sql database using the SqlDataSource already being used in the gridview the templatefield is in and a buttonfield using an update function? I was just wondering if anybody has any idea how to get this to work because I haven't been able to find any way of doing this.
Please let me know if any of you need any more information to help you solve this dilemma.
I am able to get the information to feed back into the SQL server if i enable edit and change the information in the textbox as well as another column's field in the same row, but it won't update if I only change the information in the textbox whether in edit mode or just clicking the update button.

So, changing the property of the SQLdatabase from CompareAllValues to OverwriteChanges fixed this issue. It is now allowing the changes to be written back to the sql database by just changing the textbox in the row/column that needed to be updated without having to change anything else.
