DataGrid - Weird Update Command Problem

BW
Hello,

I am attempting to to take edited values from a datagrid control and update
the underlying database. Problem is that some of the edited values don quite
seem to make it to my update sub. My code is shown below. The values that
are not appearing are Cell(4) - sCompletion and Cell(5) - sNote. The other
values show up just fine.

What am I missing here?

Bernard

Dim iLogID As String = Convert.ToStrin g(e.Item.Cells( 0).Text)

Dim sEntry As String = CType(e.Item.Ce lls(2).Controls (0), TextBox).Text

Dim sResp As String = CType(e.Item.Ce lls(3).Controls (1),
DropDownList).S electedItem.Val ue

Dim sCompletion As String = CType(e.Item.Ce lls(4).Controls (0), TextBox).Text
'Now.Date.ToStr ing

Dim sNote As String = CType(e.Item.Ce lls(5).Controls (0), TextBox).Text

If sNote = "" Then sNote = "*"

'Fill a string builder just to check values passed by DataGrid

Dim sb = New StringBuilder

sb.Append("LogI tem = " & iLogID)

sb.Append("; EntryDate: " & sEntry)

sb.Append("; Responsible: " & sResp)

sb.Append("; Completion Date: " & sCompletion)

sb.Append("; Note: " & sNote)

Label1.Text = sb.ToString

Found it thanks to Scott Mitchell's book: "Asp.Net Data Web Controls Kick
Start."

Needed to assign OnEdi/Cancel/Update/Delete commands for the grid. Also
added postback check in page load event. If the page is posted back, fill
the grid. If not, do the update.

If Not IsPostBack() Then
FillGrid()
End If

Thanks Scott!
PS - Great Book!

Hi, I almost have my nested datagrid working properly. I created a datagrid on a user control and dropped that onto another datagrid. At first, I noticed when I was stepping through the code, that the update linkbutton actually goes to the edit command instead of the update command (which I'm pretty sure would be a bug). Anyway, I took out the editcommmand column and replaced it with a regular template column. Within the...

I'm having major problems with Datagrid and the update command. Basically when I enter into edit mode in my data grid then set a new value, the update command is not picking up the new value. So, if the original value is 10, and I change it to 20 the txtFieldName.Text field still thinks it has the old value of 10 in it. Anyone any ideas why!!!

Helo All, If some one has faced a similar issue.. My datagrid Update command is not getting fired in fact it seems that the no event fires on clicking the update link. Although the cancel and the Edit Commmand are getting fired properly. The One difference I have seen is that in the task bar ..on hovering on the link the javascript for the update link seems different. I dont know if it makes sense..

In the past, I have filled a datagrid with data from an Access database table using a data adapter and dataset, where I used the OleDbCommandBuilder to have the program create the insert, delete and update commands automatically for the dataadapter. I think those database tables had no more than 10 or 12 fields. Then to save the changes in the datagrid to the database, I simply evoked the dataadapter update command. No problems. ...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
