link data grid edit button

[John M]

Hello,

In Visual studio .NET 2003,

On datagrid object :
How can I link the button element : edit, to do a some client events (such
as message box,
and do another event just after that to the server (do some manipulation on
the database).

If I cannot - how can I do that anyway in some tricky way ?

Thanks :)

Create a web control library named as MyControlLibrary and following code...
And use this control in anywhere... Feel free to built on something on

Hi John,

You can use buttonObject.Attributes.Add method add client-
side javascript method. Following code snippet shows how
to add client-side message box code:

Suppose you have EditCommandColumn as the first column of
the datagrid. In datagrid_ItemDataBound event:

if (e.Item.ItemType == ListItemType.Item ||
e.Item.ItemType == ListItemType.AlternatingItem )
{
LinkButton editBtn = (LinkButton)e.Item.Cells
[0].Controls[0];
editBtn.Attributes.Add("Onclick","alert('Edit
Message');");
}

Good,

I have tried the following vb code,
but (I have three columns, one is the "edit").
cn.controls.count is always 0
(I have tried to change e.item.cell(0), e.item.cell(1), e.item.cell(2) )

So I didn't manage running the code.

Thanks :)

Dim editBtn As LinkButton
Dim cn As Control
Dim c As TableCell
If e.Item.ItemType = ListItemType.Item Or ListItemType.AlternatingItem Then
c = e.Item.Cells(0)
cn = c
editBtn = cn.Controls(0)
editBtn.Attributes.Add("Onclick", "Alert('Edit Message')")
End If

Hi John,

I suppose index = 2 should work. Anyway, try foolowing code:

Dim editBtn As LinkButton
If e.Item.ItemType = ListItemType.Item OrElse ListItemType.AlternatingItem
Then
editBtn = CType(e.Item.Cells(2).Controls(0), LinkButton)
editBtn.Attributes.Add("Onclick", "Alert('Edit Message')")
End If

I did as your advise.

Still,
controls.count is 0,
so the code run of exception outofrange.
(Maybe not "controls", but something else).

Thanks :)

[John M]

Ignore the last,

I found it (itemIndex = -1, and that's why controls.count = 0),
so I add in the code :
If e.Item.ItemIndex <> -1 Then ...

Another thing is that I see that the page is refreshing (page_load event
occurs),
but the command editBtn.Attributes.Add("Onclick", "Alert('Edit Message')")
is not doing anything.
(There is no message box).
Why ?

Thanks :)

did you mean : new web user control ?

Thank you Elton W.
Thank you Yunus Emre.

I combine your both replies :
The line I correct is :
editBtn.Attributes.Add("onclick", String.Format("alert(""abc"")"))

(Adding string.format ...)

(The another thing is that page need to reload on every click)

But now Everything works fine ...
Thanks :)

[Elton W]

itemIndex = -1 means ListItemType.Header.

So you have to use

If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType =
ListItemType.Item = ListItemType.AlternatingItem Then

rather than

If e.Item.ItemType = ListItemType.Item OrElse ListItemType.AlternatingItem
Then

That condition will bypass Header, Footer, Separator, Pager items.
