How to get the scrollheight in the gridview?

[Suneco]

Greetings!

I was curious about how to get the scrollheight in a gridview. Because if i click a row in the gridview when the gridview is scrolled down, my context menu appear almost at the bottem of the page. But if the grid isn`t scrolled, the context menu appears as it should be. So i`m searching for a way to maintain the contextmenu within the gridview. I think the scrollheight can help me with that.

If you know a solution for this, please reply! ( or a solution without the scrollheight).

Thanks in forward!

Hi Jeroen,

The ScrollHeight of RadGrid can be retrieved client-side with this Javascript expression:

var scrollHeight = gridObject.GridDataDiv.scrollHeight;

You may also need:

var scrollTopOffset = gridObject.GridDataDiv.scrollTop;

I am not really sure what the problem is in your scenario. Here is a demo, which works as expected if you enable RadGrid scrolling. You can compare with your implementation:

Hi,

I've tried the following function to set the scrollheight in the OnGridCreated-Event, but it dose not work:

            function SetGridH() {
 
                var oGrid = $find("<%= SOExplorer.ClientID %>");
                if (oGrid != null) {
                    var scrollArea = oGrid.GridDataDiv;
                    scrollArea.style.height = "250px";
                    oGrid.repaint();
                }
            }

Hi Detlef,

I tried your code in a test project and it worked as expected on my side. I am attaching the page for your reference. Can you tell what is different on your side?
