Hi,

So you know the requirements now. To repeat: I have a read-only hierarchical WebGrid. 

I am sorry but I don't quite understand about your requirement now. I know what you want to achieve but it seems your scenario is too complex. Would you mind to send me a simple sample that replicates the issue that you said in this scenario?
It would be more easier if we can meet up the perception.
I am sorry if there are any missunderstanding parts.

Hello Madhavan,

Ok, I would discuss this issue with our developer teams.
However, I suggest you to use XHTML standard doctype and attribute for the best result.
If you use a tool such as xhtml w3c for xhtml validation, the page will fail.

You can also refer to the post in link below, to see that there is XHTML validation issue in SP2010.
Please let me know your response.

Hello Shawn,

I did not face the issue in tooltip at all. Would you mind to send me a simple sample of yours? 
FYI, I also tested with your snippet code.

Hello Madhavan,

For height issue, I believe, you can see the thread in this link.
I tested your sample. It can be also replicated without Sharepoint. The issue is under your xhtml attribute type.

 Please change it into

Hello Shawn,

Do you mean for each cell? Because we don't have EditType for row. We only have EditType for WebGrid Column in cell level.
You should not be able to do at row level. Besides, Row object does not have SetText() method.

In order to do this in No Edit type, you can use SetText(). Please see the code below.

function Button1_onclick() {
            var grid = ISGetObject("WebGrid1");
            grid.GetSelectedObject().ToRowObject().GetCells()[1].SetText("Hello World", true,true);
           
        }

The last parameter is ignore edit type parameter. You can return true or false.
