Hello,
I have a gridview control bound to a objectdatasource.
The primary key column is on the grid but made visible = false.
Because the column is invisible I cant get to the cell value when the user
presses
the edit button on the grid.
Code

Sub CustomersGridView_RowEditing(ByVal sender As Object, ByVal e As
GridViewEditEventArgs)


        String bedpID = CustomersGridView.Rows(e.NewEditIndex).Cells(1).Text
end sub

I have set up the  grdBedpDetails.DataKeyNames property
but this is only useful in the selectedindex event not the RowEditing event

CustomersGridView.Rows(e.NewEditIndex).Cells(1).Text return a empty string
because the column is invisible.

Thanks

any help Bump...

Hi,

Thank you for posting here!

I notice that you have posted the same question in our
dotnet.languages.csharp newsgroup, which I have already responded. So
please check my answer there and if you need any further assistance on this
particular issue, please reply to me in that thread so I can follow up with
you in time.

For your convenience, I have included my reply as follows:

--------------------
You have two options to get the hidden columns' values depending on whether
or not the columns belong to the DataKeyNames property of GridView.

1) If the hidden columns are included in DataKeyNames:

int id = (int) grdBedpDetails.DataKeys[e.NewEditIndex].Values[0];

2) If the hidden columns are not included in DataKeyNames:

Since hidden columns are not rendered to the client, you need to hide the
columns using CSS rule instead of setting its property Visible="false".
Below are the detailed steps:

a) Create a CSS rule in html header:

    <style type="text/css">
    .hidden { display: none; }
    </style>

b) Hide a column by applying CSS class to its header and item:

    <asp:BoundField DataField="ID" HeaderStyle-CssClass="hidden"
ItemStyle-CssClass="hidden" />

c) Then you can get the ID column text by:

    String bedpID = grdBedpDetails.Rows[e.NewEditIndex].Cells[1].Text;

----------

Thank you and have a nice day!
