I can retrieve the value from gridview but i cann't if the value is
invisible in gridview. If i read the value that is hidden i got the
value null. I don't know why. if someone know, please let me know.

my code is as follow

protected void GridView3_RowUpdating(object sender,
GridViewUpdateEventArgs e)
{
int a = GridView3.EditIndex;

Control ctl = GridView3.Rows[a].Controls[0];
string value =
((System.Web.UI.WebControls.TextBox)(ctl.Controls[1])).Text;

Control ctl1 = GridView3.Rows[a].Controls[1];
string value1 =
((System.Web.UI.WebControls.TextBox)(ctl1.Controls [1])).Text;

Control ctl2 = GridView3.Rows[a].Controls[3];
string value2 =
((System.Web.UI.WebControls.TextBox)(ctl2.Controls [1])).Text;


}

i got value and value1 but didn't get value2 because i make it invisible
in gridview. i want to have this. please help me.

Thanks a lot!

Server controls with Visible=false don't get rendered to client and don't
come back in postbacks. That's why you can't retrieve them. Leave
Visible=true and hide the control with a css rule display:none.

Rather than 'hiding' your values using formatting, use the zero-based
dataview datakeynames properties. Set the applicable columns in your
datakeynames then retreave their values using the following, probably in the
dataview's selectedindexchanged event:
Me.gridview1.SelectedDataKey.Item(0).ToString

Fantastic, Eliyahu. Of all the solutions to this problem, I think this is
the best.

Eliyahn -- I have a SQL Sever table that includes Client Data -- I created
an AJAXenabled Web Site with a TextBoxSSN, a SQLDataSource, and an
ASPxGridView (from DevExpress). In my Select Query, I've included a WHERE
Clause (WHERE (SSN = @SSN) and the following Parameter: SSN =
TextBoxSSN.Text

SSN is a PrimaryKey in my SQL Server table. I have set Visible option for
the SSN field to FALSE (to comply with HIPPA guidelines), but when I do
this, I'm not able to UPDATE or DELETE records. How can I ADD, UPDATE,
DELETE records in the SQL Server table without showing the SSN field?

I read your post about setting Visible=True, and hidding the control with a
css rule display none -- where do I create this css rule?

Thanks in advance for your (or anyone else's) assistance on this.

Here's my SELECT Statement

SELECT SSN, MaskedSSN, LAST_NAME, FIRST_NAME, MI, DOB, STREET_1, CITY_1,
STATE_1, ZIP_1, ACTIVE_ADDR, STREET_2, CITY_2, STATE_2, ZIP_2, PHONE_1,
PHONE_2, MOBILE_PHONE, EMAIL_1, EMAIL_2
FROM tblClient WHERE (SSN = @SSN)
