Protected Sub gvdVIEW_RowDataBound(
If e.Row().RowIndex -1 Then
Try
Dim lti As Literal
Dim inttotal As Integer = 0

lti = e.Row.FindControl(”total”)

Dim int As Integer = 0
For int = 1 To 5

If e.Row.Cells(int).Text “0″ Then
inttotal = inttotal + e.Row.Cells(int).Text
Else
e.Row.Cells(int).Text = String.Empty
End If

Next
lti.Text = inttotal

Catch ex As Exception

End Try
End If

Please fix loop index as per your coding.
It will work.

Hi,

In this article there are 2 approaches described by rana and Sumit. Thanks for nice codes.

There is an another approach for retrieving hidden cell data from a GridView. I have tested it for a column which is other then a key field and it works fine.

steps…

1. sample.aspx: Consider that you have following field at 4th cell (i.e., index=3) in your gridview, which is not set as invisible at design time..

…
…

2. sample.aspx.cs:

Add RowDataBound() event for your gridview.

protected void gridview_RowDataBound(object sender, GridViewEventArgs e)
{
…
…
e.Row.Cells[3].Visible = false;
// same for other cells – to set invisible
…
…
}

Note:- This will set the visibility during run time. So no need to use a css file to do the same task.

3. Retrieving data: Just call the data from the cell as follows:

…
…
txtTechPersonName.Text = gridview.Cells[3].Text;
…
…

It works fine for me, hope it will work for you too.

Hi All,
I have created the Grid view as following and i am able to get the value of that hidden filed. you can also use it.

Its my grid view code.
I have just specified the css class = “invisible” which is as following:

.invisible
{
width:0px;
display:none:
}

Now u can use the row index and the column index for that column and use the value of it.
