Hello,

I have a bound field set to visible="false". I have a custom command button, which posts back and I want to get the value of this field that is set to visible="false". Basically, this field is an ID field, and I don't want to show it in the gridview, but I want to be able to access the value. I have this code in the RowCommand event:


Protected Sub gvwTables_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs ) Handles gvwTables.RowCommand

If (e.CommandName = "Columns") Then

Dim intRow As Integer = CType(e.CommandArgument, Integer)

Dim objRow As GridViewRow = CType(sender, GridView).Rows(intRow)

If (Not IsNothing(objRow)) Then

Response.Write(objRow.Cells(2).Text)

End If

End If

End Sub

But I can't get the value through the Text property. I have the column set up as:


<asp:BoundField DataField="StructureID" HeaderText="Structure ID" Visible="False" DataFormatString="{0}" SortExpression="StructureID" />

Should I be able to access this field through the text property as such? Nothing gets returned but I know a value exists (tested the underlying stored procedure. If not, what do I need to do?

Thanks.

Brian

Hi Brian,

I ran a few tests and I am seeing the exact same thing. I was expecting that the column would be there, with its value in the cells. I don't know a way around this with your current setup.

However, can't you use the DataKeys collection for this? If the field is an ID, the DataKeys collection would make sense. Alternatively, you could bind the CommandArgument to the ID....

Brian,

I know you can use the following to retrieve the underlying data in the hidden field in the RowDataBound event:

System.Web.UI.DataBinder.Eval(e.Row.DataItem, "StructureID")

I have not tested it in the RowCommand event but I don't know why it would not work there also.
