Hello,

I have a <DIV> in my Datagrid which produces scrollbars
when it is populated. When I click the Edit button in the
edit comand column I need to be able to maintain the
scroll position. According to MSDN, setting
SmartNavigation="True" in the @Page directive will achieve
this but unfortunately it does not, does anybody know how
to do this? I have found an article explaining how to do
this with c# (by creating a Inet Explorer behaviour) but I
am using vb and want to keep it as simple as possible if I
can?

Cheers

Rob

I think this will do what you want. it is very simple to use. download
it to yu bin directory.
put
<%@ Register TagPrefix="cc1" Namespace="StrengthControls.Scrolling"
Assembly="StrengthControls.Scrolling" %>

at the top of your aspx, and

<cc1:SmartScroller id="SmartScroller1" runat="server" />

somwhere in the <body> of your document.

Smartnavigation = evil imho, only "works" on ie browser, and seems to
create more hassles than its worth. set to "false"!

Hi Rob, not sure smartnav works well with grids, i doubt itll keep
position within DIV, it only keeps scroll position on the main scroll
bar.

Anyway , we did the following to keep edit position on the edit
selected with a DIV:

add the follwing to the main class variables of the form:
private int itemCount = 0;

In the ItemDataBound event of your grid add the following code to add
a number bookmark to each row in the grid that is created:
//************ItemDataBound**************************
// placing a bookmark against the first column
LiteralControl anchor = new LiteralControl();
anchor.Text = "<a name=\"" + itemCount.ToString() + "\">";
itemCount ++;
e.Item.Cells[0].Controls.Add(anchor);
//************ItemDataBound**************************

Then in the EditCommand event method add the following code to get the
browser to jump to the item when the page reloads:
//*************EditCommand **************************
System.Text.StringBuilder jScript = new System.Text.StringBuilder();
jScript.Append("<script language=\"JavaScript\">");
jScript.Append("location.href=\"#");
jScript.Append(e.Item.ItemIndex.ToString());
jScript.Append("\";");
jScript.Append("</script>");

this.RegisterClientScriptBlock("Bookmark", jScript.ToString());
//************EditCommand *************************

You may then want to add the above edit commmand code into any method
that ou want to retain position, e.g. UpdateCommand and CancelCommand.
We put the above code into a function and passed in the ItemIndex from
whatever event function was called (SelectCommand, EditCommmand,
UpdateCOmmand, CancelCommand

Hope that helps.
