Hi,

I'm newbie in RadGrid.  I'm trying to implement the "Resizing grid with scrolling when data is less than scroll height" by following the RadControls document.
My version is Q2 2008.

The following taken from document :
<script type="text/javascript">
 
function GridCreated(sender, args)
 {
    var scrollArea = sender.GridDataDiv;
    var dataHeight = sender.get_masterTableView().get_element().clientHeight;
    if(dataHeight
< 350)
    {
       scrollArea.style.
height = dataHeight + 17 + "px";
    }
 }


However, it stopped at
 
scrollArea.style.height = dataHeight + 17 + "px";
with error" Object expected".

It seems
scrollArea.style.height expects an object as input rather than a string.

Please advise,
Wilson

Hi,

Actually, the problem is occurred if I injected the script block in code-behind.

Dim script as string = "function GridCreated(sender, args)" + vbCrLf + _
                                "{" + vbCrLf + _
                                    "var scrollArea = sender.GridDataDiv;" + vbCrLf + _
                                    " alert(scrollArea.style.height);" + vbCrLf + _
                                    "var dataHeight = sender.get_masterTableView().get_element().clientHeight;" + vbCrLf + _
                                    " alert(dataHeight);" + vbCrLf + _
                                    "If (dataHeight < " + sScrollHeight + ")" + vbCrLf + _
                                    "{" + vbCrLf + _
                                        "scrollArea.style.height=dataHeight + 17 + ""px""; " + vbCrLf + _
                                    " }" + vbCrLf + _
                                    "}"

 ScriptManager.RegisterClientScriptBlock(Me, GetType(Page), "GridCreated", script, True)


As I cannot hardcode it in aspx page,  would u please advise any possible way to implement it.

Thanks,
Wilson

Hi,

I figured out the problem.  It was caused by copy and paste action.
VS changed "if" to "If" automatically.

Cheers,
Wilson
