Custom Toolbar for Detail Grids

[kieran]

Hi.

I am trying to have a set of controls at the foot of every detail grid. These controls are not paging controls or edit controls, but I am using a Pager Template to place them where I want them. The result is something like this:

Outer Row
   Inner Row
   Inner Row
   Inner Row
      [list box] [button]
Outer Row
   Inner Row
   Inner Row
      [list box] [button]

My problem is that the contents of the list box should be different for each inner grid and I don't know how to get at the control or it's construction to do that.

Is there a way to do this? Or am I looking in entirely the wrong direction?

Thanks.

OK. I see now I should be using a CommandItem template.

I still have a problem though. Aswers elsewhere indicate that I should be setting the state of my control (in this case populating my list box) in the OnPreInit handler. I set this on the detail table, but it never seems to fire.

My real problem is that the contents of the list box depends on a value in the current outer row.

Any suggestions?

I worked it out.

In a method bound to the OnItemCreated event of the master table, I query for the data key value and select based on that.

        if (e.Item is GridCommandItem)
        {
            GridItem commandItem = e.Item as GridCommandItem;
            DropDownList events = (DropDownList) commandItem.FindControl("MyDropDownList");

            IRepository rep = RemoteServer.GetRepository();
            string id = commandItem.OwnerTableView.DataKeyValues[0]["ID"].ToString();
            events.DataSource = rep.GetScheduledEventsFor(id);
            events.DataTextField = "Date";
            events.DataValueField = "ID";
         }

I don't know what one would do if the value you wanted wasn't a key column.
