I'm sorry that this is the second time I have to create a new thread on an already opened question that I posted a few days ago, but this is the second time I cannot follow the link from the email response to my question. Yesterday I had to start another thread also, and now I can follow the second followup on it. I get an internal error and also do not see the post when I search for it. tti

Before I post the prior stuff for it, I am getting the same error using the sample code that Shinu gave me as I did before. There error I am getting is A control is already associated with the element and it seems like it does not have anything to do with the grid. The resonse I got from Shinu was:

First you need to make sure that the tooltip is coming correctly when hover the link, try the folowing trick to test whether it is appearing correctly. place the aliasGrid inside one panel, put one label also to test whether the arg values are coming passing correctly.

I don't know how to tell if it is appearing correctly...all i know is I am getting the same error as before and the code that is throwing the error is:

]);

if (e) throw e;

if (typeof(element.control) != 'undefined') throw Error.invalidOperation(Sys.Res.controlAlreadyDefined);

Sys.UI.Control.initializeBase(

this);

this._element = element;

element.control =

this;

My code looks like this:

    
                    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)  
        
                    {  
        
                        Label Label1 = (Label)e.Item.FindControl("Label1");  
        
                        //Add the Label id to the tooltip manager    
        
                        try 
        
                        {  
        
                            System.Data.DataRowView currentRow = (System.Data.DataRowView)e.Item.DataItem;

                    }  
        
                    protected void updateToolTip(string elementID, UpdatePanel panel)

Here is some history from the response to the thread I recieved in the email:

    
            From: Laura  
        
            Date: 11/27/2008 4:08:30 PM  
        
            I wrote a question to the forum the other day about using a tooltip for a template column and displaying the detail items in a grid in a tooltip for a specific column. What I want to do is this: I have a grid of providers and a template column which is primary provider alias. I have another table called provider_aliases which is all the aliases for each provider. I want to hover over the primary alias and show a tooltip of all provider_aliases. I got a great answer here telling me to use the tooltipmananger and on the ajaxrequest to load the alias grid into the tooltip and tried to implement it and I am 90% there. The forum post is gone and I still need a little help, so I am reposting it by copying parts from the email I recieved when I got the answer. I don't know why I cant access the original post.  
        
            Shinu helped me greatly with this answer:  
        
            From: Shinu  
        
            Date: 11/26/2008 5:18:38 AM  
        
            Hi Laura,  
        
            I have one suggestion for doing this instead of adding the tooltip inside the template column with the "aliasGrid ",  
        
            place the aliasGrid outside the RadGrid1 and use the tooltip manager as explained in the demo  to show the related alias's  on hover the label.  
        
            Radgrid1 with Label in the tempplate column.  
        
            ..........

Here is the last reply I got from Shinu:

place the aliasGrid inside one panel, put one label also to test whether the arg values are coming passing correctly.

I don't this they are being passed correctly. What should I do next?
