Default value when editing

[Anders]

Hello
I am trying to autofill two of the many textboxes in my Radgrid. I want the first textbox to have the username of the logged on user and the other textbox should have current date and time.
With the help of another post I have managed this when creating a new record, but not when editing an existing record.
To be clear, if I edit an existing post I want the textboxes to have new values, current datetime and looged on user.
Here is my code:

Protected Sub RadGrid1_ItemCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

        If (e.CommandName = RadGrid.InitInsertCommandName) Then

            e.Canceled = True
            Dim loggedInUser = User.Identity.Name.ToString()
            Dim myDate As Date = Now()

            Dim defaultValue As System.Collections.Specialized.ListDictionary = New System.Collections.Specialized.ListDictionary()
            defaultValue("LastUpdated") = myDate.ToString()
            defaultValue("LastUpdatedBy") = loggedInUser.ToString()

            e.Item.OwnerTableView.InsertItem(defaultValue)
            End If
    End Sub

Thanks.

Hi Anders,

When you a have a BoundColumn in edit, it will automatically bind the textbox in edit to the corresponding value of that row. You can update this row on UpdateCommand and store to db.

ASPX:

<telerik:GridBoundColumn DataField="LastUpdatedBy" HeaderText="LastUpdatedBy" UniqueName="LastUpdatedBy">
</telerik:GridBoundColumn>

VB:

Protected Sub RadGrid1_UpdateCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.UpdateCommand
  If TypeOf e.Item Is GridEditableItem Then
    Dim editItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)
      'Access the column in editmode and get the entered text
    Dim txtUser As TextBox = DirectCast(editItem("LastUpdatedBy").Controls(0), TextBox)
    Dim user As String = txtUser.Text
      'Code to save to DB
  End If
End Sub

Thanks,
Princy

Hi Princy and thank you for respondning.

I still dont understand how to set LastUpdatedBy with my new value, what do I write after 'Code to save to DB?

Since these two fields is to be set dynamic I'm thinking of making them not visible. Will that be a problem?

Hi Anders,

I'm not clear about your requirement. If you donot want to show a column in view you can set its Display as false, and in edit mode if you want to set a default value you can try the following code snippet.

VB:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound
    If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
        Dim edit As GridEditableItem = DirectCast(e.Item, GridEditableItem)
        Dim txtLastUpdatedBy As TextBox = DirectCast(edit("LastUpdatedBy").Controls(0), TextBox)
        txtLastUpdatedBy.Text = "Some Value"
    End If
End Sub

In case if you donot want to show it in editmode, then set its ReadOnly property as true and in UpdateCommand you can assign the value and do the Update operation.
If this doesn't help, please provide your full code snippet.

Thanks,
Princy

That is exactly what I wanted.
Thank you.
