Maintain State after postback

[rikb53]

i can highlight a dataGrid row thru javascript or in the code behind with the OnItemDataBound Event of the grid.
and yes it highlights, and then goes away on Postback. anyway to make it stick until say an event of maybe a button Click is fired.

Public Sub dtgCustomers_ItemDataBound(ByVal sender As Object, ByVal e As DataGridItemEventArgs)
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
e.Item.Attributes.Add("onclick", "this.style.backgroundColor='Yellow'")
End If
End Sub

this works, then goes away on postback
anyideas how to maintain this state????
thanks

I sure wish we had more .NET guys around here. Ryan was our resident guru, but he doesn't come around much anymore.

darn, i know there's got to be a way either by session state or Caching - but i hate to use a Cach when data will be going in and out

i found my answer. its a limitation of the datagrid
A row is selected only if the user clicks the column button associated with the Select command.
There is an architectural issue behind this limitation.
To process the selection event on the server, you need an interactive element on the page that, when clicked, posts back to the server.”

A selected row can have a custom style that you specify by using the SelectedItemStyle property;
Only one row in the DataGrid control can be selected at any time. Multiple selection is not supported.(aka - ListBox)
A row is selected only if the user clicks the column button associated with the Select command And you can get the info for all the cells (e.Item.Cells(0).text = e.Item.Cells(1).text etc)
Each select column must be created using the ButtonColumn class with the CommandName property set to select.
The user can select the row by clicking any of these columns and choose any color which will remain after post-back

Have you tried enabling ViewState?

Also, on post backs, the page_load event is triggered every time a server request occurs. Try using

If Not Page.IsPostBack Then

'some code

End If

This will allow you to keep function calls from being triggered in the event that the page is posted back to the server.
