window.status messages for sort and hyperlink columns

[Michael Hetrick]

I would like to have a friendly status message onMouseOver of sort columns
in the datagrid. Instead of the standard "javascript:__doPostBack...", I
would like to have status bar show "Sort By [ColumnName]".

Likewise, I would like to be able to have status messages based on row for
the grid's HyperlinkColumn as in "View Details for [Item]".

How would I go about doing this? Thanks in advance...

Hello Michael,

If we want to manipulate controls in a DataGrid, we need to intercept the ItemCreated or ItemDataBound event of the
DataGrid, e.g.

DataGrid1.ItemCreated += new DataGridItemEventHandler(ItemCreatedHandler);

Now you get a call to your function (here: ItemCreatedHandler) for every item of the DataGrid. You have to filter for the item(s)
you want to add your javascript code to. For an example:

Private Sub MyDataGrid_ItemCreated _
(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) _
Handles MyDataGrid.ItemCreated
Dim dgItem As DataGridItem
dgItem = e.Item
If dgItem.ItemType = ListItemType.AlternatingItem _
Or dgItem.ItemType = ListItemType.Item Then
dgItem.Attributes.Add("onmouseover", _
"window.status='select article Xx';")
End If
End Sub

Hope this helps

Thanks! That got me off to a good start. I've switched to tooltips instead
of window.status. I have some questions about how to get the text in a
datagrid cell - specifically in the else if block below:

private void DataGrid1_ItemCreated(object sender,
System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Header)
{
//Text works because there is a link button in the header
((LinkButton)e.Item.Cells[1].Controls[0]).ToolTip = "Sort by " +
((LinkButton)e.Item.Cells[2].Controls[0]).Text;
}
else if ((e.Item.ItemType == ListItemType.AlternatingItem) ||
(e.Item.ItemType == ListItemType.Item))
{
//How do I find the text in a HyperLink column? I want the link
text to appear where I put the ??? below:
((HyperLink)e.Item.Cells[1].Controls[0]).ToolTip = "View Details for
" + ???;
}
}

In the if block, I can get the cell text from the link button's text
property, but the accessing the cell text from the HyperLink column just
isn't working. Thanks in advance.

Hello Michael,
