Hi,
i have a datagrid that has delete link,what i want to do is when the user click on the delete he gets a message to ask him if he is sure that he wants to delete this row from the table,is this possible?

Yes it is possible.Add event for the delete button using [controlname].attributes.add("onClick","javascript:alert('Do you want to delete')").

Well Santhi, it should be confirm insted of alert. alert will have only one option "OK". The user cannot make a decision. The decision box is confirm

Regards
Ganesh

yes but the button is defined as follows:
<asp:ButtonColumn Text="Delete" HeaderText="Delete" CommandName="Delete" >

and there is no attribute called onclick ,so where shall i add this code?

Hi Noor ,
    Ganesh is right..YOu should use Confirm instead of Alert.
For adding attributes to the control in datagrid,you have to create ItemCommand event handler for datagrid.Check out the link below..The link has more explanation

Noor,

I think it should be the ItemDataBound or ItemCreated insted of the ItemCommand event.

ItemCommand will only help you if you want to handle things on the postback.

ItemDataBound is where you can add attributes for the client side to controls that will show up for each row in the datagrid.

Well that was silly... Sometimes the "Submit Reply" button is just too close to this reply textbox. Accidently submitted before I finished my reply.

In the ItemDataBound handler for the datagrid, you can drill down to the individual controls in each item (e.Item, which is the grid row). You'll know the column number of your buttun column so you can directly access that delete button:

e.Item.Cells(x).Controls(0)

Convert that to a Button object, then you can add an attribute for onClick to it:

CType(e.Item.Cells(x).Controls(0), Button).Attributes("onClick") = ...

Put your confirm javascript in there, and you'll get a confirmation prompt for each delete button in the grid.

Note that you need to test e.Item.ItemType for AlternateItem or Item because that handler gets called for all items including the header, footer and pager and those won't have the delete button.

I wrote it in the delete_mydatagrid function as follows:
dim delete as =CType(e.Item.Cells(0).Controls(0), Button).Attributes("onClick") = "javascript:alert('Do you want to delete')"

but gave me an error saying(type expected)
is this the right place and right syntax for the command?

You need to put the onClick assignment in the ItemDataBound handler for the grid. This puts the confirm script into the onclick of the delete button for every row. If you do this in the delete handler itself, you'll defeat the purpose altogether because you'll have already arrived back at server-side code where you'll delete the record without prompting the user for delete confirmation.
