hi,

just like james in this thread, I need to mark certain rows according to a condition.
every time the user opens and watch an idea, the row of the watched idea should be in lightblue.
that for itself works great.
My problem is, that when I click a row it gets lightblue, but then- when I click another row, the previous row change color to white.
How can I keep the condition working for alternating item style too?

that my code :

<telerik:RadGrid Skin="innovation" EnableEmbeddedSkins="false" ID="RadGrid1"

dir="rtl" HeaderStyle-ForeColor="White" AllowFilteringByColumn="True"

AllowSorting="True" AllowPaging="True" BorderColor="#74ABAE" BackColor="White"

BorderWidth="2px" runat="server" HeaderStyle-Font-Size="Small" ItemStyle-Font-Size="Small"

AlternatingItemStyle-Font-Size="Small" ItemStyle-BackColor="White" ItemStyle-ForeColor="Black"

PageSize="7" AutoGenerateColumns="False" PagerStyle-Font-Size="Small"

AlternatingItemStyle-ForeColor="Black"

Culture="Hebrew" GridLines="Vertical" Width="666px"

style="margin-right: 30px">

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Black">

</HeaderContextMenu>

<ItemStyle BackColor="White" Font-Size="Small" ForeColor="Black" />

<PagerStyle mode="NumericPages" ShowPagerText="false"></PagerStyle>

<ClientSettings>

<Selecting AllowRowSelect="true" />

<ClientEvents OnRowSelected="OpenIdea" />

<FilterMenu EnableImageSprites="False"></FilterMenu>

</telerik:RadGrid>

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

Try

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = CType(e.Item, GridDataItem)

Dim idea_code As Integer = CInt(item("IDEA_CODE").Text)

If (StoredProcedures.Is_Watched_Idea(idea_code, userID) = True) Then 'if the ideas was watched then

item.BackColor = Drawing.Color.LightBlue 'color the row

End If

….

End sub

by the way- I tried disable alternating row in client settings but all I got is a transparent back color for the alternative rows.

can anyone help with that?
kind regards, Dana

Hi ,
I still don't get it- I'm not sorting or changing anything, I simply click on an other row, and I want to keep the previous style for rows that are watched.
there's no postback or anything and I'm not
example:
if I load the grid and my first 3 rows are blue (meaning I watched these ideas before according to my condition) and than the next 3 are white, by clicking a blue row and then a white row, the blue row - as an alternate row- becomes white (and the white becomes blue because of the condition I added)
Is there a way to store my style for each row? or maybe there's an event I can use that I can rebind my grid after every row click so it'll check my condition everytime?
