Another option is that you can create the handler for the Deleting event of the ObjectDataSource control, in the handler you can set the Id or whatever property of the BO object stored in the e.InputParameters collection, this object is then passed to the Delete method as the parameter.

hmmmm.....not a very good thing for a !..Web Guru..! to say...
You'll probably find that they're all pretty complex - in order to appeal to as wide an audience as possible, they must contain as many features as possible - meaning that they complicate quickly and tend to have fairly steep learning curves....
AJAX isn't difficult - why not try creating your own controls and components derived from the standard ones?

I have created a table on my page dynamically and in each cell I want to create a hyperlink that is invisible to the user but one 'clicked' will allow me to program the event in my code behind page which is vb.net? I cannot access the html code of the hyperlink as it is created on the fly.
From what I understand does the hyperlink not have an onclick event that can be responded to?
I am trying to mimic an excel spreadsheet with my table and want the user to click in a cell and have the background change to black to make the cell look selected.
I have this: (this is just part of it)
MyTable.Rows(i + 1).Cells(k + 1).BackColor = System.Drawing.Color.Black
Dim strHello As String
strHello = "Edit"
Dim e_link As HyperLink = New HyperLink
MyTable.Rows(i + 1).Cells(k + 1).Controls.Add(e_link)
If IsPostBack Then
MyTable.Rows(i + 1).Cells(k + 1).HorizontalAlign = HorizontalAlign.Center
e_link.ForeColor() = System.Drawing.Color.Black
e_link.Text = strHello
AddHandler e_link.Click, AddressOf e_link_Click
with this event handler placed lower
Private Sub e_link_Click(ByVal sender As Object, ByVal e As EventArgs)
Response.Write("You clicked Me!")
End Sub
Thanks

It would probably be simpler to achieve this using client side scripting. The problem will be that a) no OnClick event, and b) even if you do manage to catch SOMETHING, it'll need a postback to update the cell colour.
If you were to do it on the client side, you can assign an onclick handler to each element, then use a simple style.background='#xxxxxx' kinda thing to change the cell's background color.

I want to test the condition of whether or not the cell was clicked in and if it is presently a white background then change it to black to signify that it was selected.
How can I write that in vb.net? If the buttonlink does not yet exist untilt he page loads how can I access it from client script? Sorry if I appear stupid - I just may be. . . . . but hopefully just new to it all.
I have this so far:
If e_link.OnClick = True Then
if (e_link.ForeColor() = System.Drawing.Color.Black)then
e_link.ForeColor() = System.Drawing.Color.White
End If
End if
I have an error on this line: e_link.OnClick can you test this at all?
Thx, tammy

Ok I have switched out my hyperlink for a linkbutton as such:
Dim e_link As LinkButton = New LinkButton
MyTable.Rows(i + 1).Cells(k + 1).Controls.Add(e_link)
Now how do I actually test if the button was clicked? I am not sure how to handle events in vb.net as much as c#.
I have this line:
AddHandler e_link.Click, AddressOf e_link_Click
With this sub below:
Private Sub e_link_Click(ByVal sender As Object, ByVal e As EventArgs)
Response.Write("You clicked Me!")
End Sub
How to I actually call the event based on whether the link is clicked? Sorry if this sounds very simple - I am new to all of this.
I want to check that the cell(linkbutton) was clicked and if so perform my event.
Something like :
if e_link.click = true then . . . . .

Well, what you're doing with the event handler sounds good to me. I'm also a C# programmer starting to dabble in VB, so I'm not 100% sure. All I would suggest you add is a CommandName and CommandArgument. That way, when you get the handler method, you can pull out the CommandArgument which will have whatever pertinent information you wanted to be attached to that link. For instance, you could be the index of the cell in there.

As far as I can tell there's no click event associated to the Hyperlink webcontrol. There is a ServerClick event for the HtmlAnchor control however, that will qualify for what you're trying to do.
Personally I'd try to work with the Attributes collection of the HyperLink or the Style collection of the table cell.
Hope this helps,
Patt

Hi,
In a DataGrid I have placed a comandField select button. This field sometimes shows a text value and should sometimes show the select button instead (Depending on the business rule).
How can I make the select button to appear?
I basically want to put the code where the question mark is to show the button instead of the text.
i.e.
in grid_RowDataBound event
If (e.Row.RowType = DataControlRowType.DataRow) Then
If Not (e.Row.DataItem("c_start_date").ToString() Is Nothing) Then
e.Row.Cells(9).Text = e.Row.DataItem("c_clinic_code").ToString() 'Change ur text here
Else
'show the accept(select) button as there is no start date...
??????????????????????
End If
End If
Thanks

You can do it in the simple way that using the Label and Button controls in the TemplateField of the GridView control. Depending on the c_start_date field value, you can display the text using the Label control and set the button invisible, otherwise make the label hidden using the Visible property. You can either set the Visible property in the RowDataBound event handler or use the data binding expression. In addition, you can also add dynamic button in this case.

It's not the permissions in IIS that is the problem, but the file permissions.
The user account running the ASP.NET code (usually ASPNET or IIS_WPG) has to have write permission to the file or the folder.
