First: thank you very much for your help.

The easiest way would be to add a confirm message to your button click event handler on the client-side.  Basically cancel the button-click if !confirm("are you sure you want to delete this row").

That is just what I want. But: where is the "button click event handler"?  If I use only one button for all the grid, selecting a row before deleting, I can add that confirmation, but in this case the button is a button per row. This is, I change the Column.Type in the Grid.InitializeLayout event, so how can I add a button click event handler to that button (really: many buttons, one per row)?
For instance, I have:
Protected Sub UltraWebGrid1_InitializeLayout(ByVal sender As Object, ByVal e As Infragistics.WebUI.UltraWebGrid.LayoutEventArgs) Handles UltraWebGrid1.InitializeLayout 

You should be able to use the ClickCellButton client-side event

This event will be fired when the button is clicked on the client-side.  In the event handler, try this code-

function CellClick(gn,cid)
{
   if(!confirm("are you sure you want to delete..")) igtbl_cancelPostBack(gn);
}

That should prompt the user with a confirm box, and prevent the postback from occuring if the user clicks cancel.

Can u  supply an example of aspx code that declares or "tells" this event to occur?

I  am using a C# code behind page. I have the postback event handler set up. That works and postback occurs until I try to implement this js confirmation function. Now the js runs, but the postback never occurs, even if the user answers OK to the prompt. Here is what I tryed to do on the aspx page to get this to work:

 <ClientSideEvents ClickCellButtonHandler="CellClick()"> </ClientSideEvents>

Also, I do not understand how I could place the cellid in the function call, as every row has a different cellid at run time, doesnt it?

 Thanks

Jeff,

client-side event handlers should be defined as the function name only. In your case above, I think including parenthesis is what's messing up the event firing.  Set ClickCellButtonHandler="CellClick", and then define

function CellClick(gridname,cellid){
//insert code here
}

the grid will automatically call the CellClick function with the correct parameters (gridname and cellid).  Pretty much every WebGrid client-side event is fired with the first parameter being the grid's id and the second parameter will be the id of the contextual object.  So in a cell event, the second parameter is the cellid.  All parameters are listed in the client-side api docs.

Tony,

 I have several buttons on the grid one being a delete button.  How can I distinquish the correct button?  Is it the same name as the key?

Thanks in advance.

You can either use the grid's BeforeDeleteRow client-side event which will only fire when a row is being deleted (through a button click or the delete key press), of you should set an explicit click handler for your button - "<button onclick='deleterow(rowid)'>Delete</button>"
