Error occuring when following RadGrid SelectedRowStyle Demo

Hi: I am attempting to follow the example exactly as listed on: http://demos.telerik.com/aspnet-ajax/grid/examples/styles/selectedrowstyle/defaultcs.aspx

I have a RadGrid with the default theme. For testing I changed it to Web20 to match the example exactly. I want to set the selected row style to have no background image but a background color of dark grey.

My markup looks like:

    
             <telerik:RadMenu runat="server" ID="NotificationRadMenu" Skin="Sitefinity"  EnableShadows="true" DefaultGroupSettings-OffsetX="-210">  
        
                        <Items> 
        
                            <telerik:RadMenuItem Visible="false" Value="label" Enabled="false"></telerik:RadMenuItem> 
        
                            <telerik:RadMenuItem Value="TemplateHeader">  
        
                                <ItemTemplate> 
        
                                    <asp:Label ID='AlertNoticeNumber' CssClass='AlertNoticeNumber' runat="server" Text="Label" Visible="false"></asp:Label> 
        
                                </ItemTemplate> 
        
                                <Items>                          
        
                                    <telerik:RadMenuItem CssClass="AlertMenuItem" Value="TemplateColumn">  
        
                                        <ItemTemplate> 
        
                                        <div class="AlertMenuItemContainer">  
        
                                        <Telerik:RadGrid RegisterWithScriptManager="true" ID="StudentCheckListRadGrid" AutoGenerateColumns="false" runat="server" AllowSorting="true" 
        
                                          AllowPaging="false" ShowHeader="false" PageSize="10" Width="100%" BorderWidth="0" ItemStyle-BackColor="#E8E8E8" AlternatingItemStyle-BackColor="White" 
        
                                          ClientSettings-EnableRowHoverStyle="false" OnSelectedIndexChanged="StudentCheckListRadGrid_SelectedIndexChanged" 
        
                                          ClientSettings-EnablePostBackOnRowClick="true" ClientSettings-Selecting-AllowRowSelect="true" Skin="Web20">   
        
                                            <MasterTableView AllowMultiColumnSorting="true" AutoGenerateColumns="false" ForeColor="#4B4B4B" Font-Names="Tahoma,Arial,Verdana" Font-Size="11px">  
        
                                            <Columns> 
        
                                                <Telerik:GridBoundColumn DataField="TaskNameCheckList" HeaderText="TaskNameCheckList"></Telerik:GridBoundColumn> 
        
                                                <Telerik:GridBoundColumn Visible="false" DataField="TaskAssociatedUserControlCheckList" HeaderText="TaskAssociatedUserControlCheckList"></Telerik:GridBoundColumn> 
        
                                            </Columns> 
        
                                            </MasterTableView>    
        
                                            </telerik:RadGrid>

I then created a Css entry

    
            tr.SelectedRow_Web20 td  
        
            {  
        
                 background-color: red;  
        
                 background-image: none;  
        
                 padding-right: 17px;  
        
            }

The row style DOES NOT CHANGE when selected. I also noticed that when I use the <SelectedItemStyle BackColor="red" /> it works okay, but when I tried <SelectedItemStyle CssClass="RedClass" /> it does not import the styles. This method would work okay if it would allow me to remove the background image. Thanks!

RadGrid Resizing Issue

Hey Telerik Team,

I'm having an issue with my RadGrid.

Details:
I had created a reporting page with a RadGrid on it, the report contains between 130 - 180 auto generated columns.
I have Allow scrolling enabled so that the grid wouldn't resize to be 20 pages long. This all worked fine. I then had to move the code to a new page using a master page template file. Now when the grid populates it resizes waaaaaaay bigger than my page size. I still get the horizontal scroll bar but it's about the size of the grid minus one column. Any ideas of why the grid is resizing so crazy now?

Here is my code:

EDIT :: CODE EDITED OUT

Any ideas are greatly appreciated.

Read grid values in edit mode

Hello everybody!

            <RowIndicatorColumn> 
        
            <HeaderStyle Width="20px"></HeaderStyle> 
        
            </RowIndicatorColumn> 
        
            <ExpandCollapseColumn> 
        
            <HeaderStyle Width="20px"></HeaderStyle> 
        
            </ExpandCollapseColumn> 
        
            <Columns> 
        
                <telerik:GridBoundColumn DataField="PurchaseRecommendationLineID" UniqueName="PurchaseRecommendationLineID" Visible="false"/> 
        
                <telerik:GridTemplateColumn UniqueName="Product" DataField="Product"  HeaderText="Tuote" > 
        
                    <EditItemTemplate> 
        
                        <asp:TextBox ID="Text" runat="server"  Text='<%#Bind("Product") %> '/> 
        
                    </EditItemTemplate> 
        
                </telerik:GridTemplateColumn> 
        
                <telerik:GridBoundColumn DataField="Unit" UniqueName="Unit" HeaderText="Yksikkö"/> 
        
                    <telerik:GridNumericColumn DataField="Quantity"  UniqueName="Quantity" HeaderText="Määrä" HeaderStyle-Width="50px" NumericType="Number"/> 
        
                 <telerik:GridBoundColumn DataField="Info" UniqueName="Info" HeaderText="Info"/> 
        
            </Columns>

I hope some can help me. I have all the grid items in Edit mode. Edit mode is done like this;

    
            protected void ProposalGrid_PreRender(object sender, EventArgs e) 
        
                    { 
        
                        if (!IsPostBack || forceEditable) 
        
                        { 
        
                            forceEditable = false; 
        
                            foreach (GridItem item in ProposalGrid.MasterTableView.Items) 
        
                            { 
        
                                if (item is GridEditableItem) 
        
                                { 
        
                                    GridEditableItem editableItem = item as GridDataItem; 
        
                                    editableItem.Edit = true; 
        
                                } 
        
                            } 
        
                        } 
        
                        ProposalGrid.Rebind(); 
        
                    }

I read Values from grid like this:

    
             private void CollectRowInformation(int headerid) 
        
                    { 
        
                     foreach (GridDataItem item in ProposalGrid.MasterTableView.Items)  
        
                        { 
        
                            RowObject ro = new RowObject(); 
        
                            ro.Rowdata.Add("Unit", item["Unit"].Text); 
        
                            ro.Rowdata.Add("Info", item["Info"].Text); 
        
                            ro.Rowdata.Add("Quantity", item["Quantity"].Text); 
        
                            ProsalService.Persist(ro); 
        
                        } 
        
            }

If I change some values in grid, and try to read it.I get always old value. I give you exsample.If Item orginal information is like this:
Unit:kg
Info:Plah
Quantity:4
And I change item information to
Unit:kg
Info:Plah2
Quantity:5555

If I put break point in CollectRowInformation and check values,It always show orginal values.How Can i read new values from grid.

Data Versioning Via Table and RadGrid

Requirements
RadControls version	RadControls for ASP.NET AJAX 2010.1 519
.NET version	2.x
Visual Studio version	2005/8
programming language	VB.NET
browser support	all browsers supported by RadControls

PROJECT DESCRIPTION
I am storing different versions of an Excel file in a SQL Server table. Each row in the file is a row in the table. Different versions are differentiated by a VersionNumber column. This code allows the user to view different versions of the file in a RadGrid. Steps:

First you will need a table defined that includes a column for the version. You will need a way to increment the version as you insert new rows to the table. I use stored procedures to insert and select from the tables.
Then:
1. Have a radgrid defined to hold the data
2. Create a drop down and link buttons to select either a given version or the current version

    
            <asp:DropDownList ID="ddlVersion" runat="server" Width="250px"> 
        
            </asp:DropDownList> 
        
            <asp:LinkButton ID="lbViewVersion" Text="View selected Version" runat="server"> 
        
            </asp:LinkButton> 
        
            <br /> 
        
            <asp:LinkButton ID="lbViewCurrentVer" Text="View current Version" runat="server"> 
        
            </asp:LinkButton>

3. Create a method to pull the data based on the ddl and link button selections

    
                Protected Sub GetInventoryData(ByVal displayType As String) 
        
                    ' set your data access here 
        
                ' ... 
        
                    Dim inventoryData As DataSet 
        
                    Try 
        
                        ' If different version is selected get the version from the drop down and pass it into a stored procedure 
        
                        If displayType = "diffVersion" Then 
        
                            Dim inParams As New NameValueCollection 
        
                            Dim version As Int16 
        
                            version = ddlVersion.SelectedValue 
        
                            With inParams 
        
                                .Add("@versionNum", version) 
        
                            End With 
        
                            inventoryData = <your data call to the stored procedure, passing in the version as input param> 
        
                        Else 
        
                    ' I go to a different table and procedure if it's current version so I need an else without input params 
        
                            inventoryData = <your data call to the stored procedure> 
        
                        End If 
        
                        rgridInventory.DataSource = inventoryData 
        
                        rgridInventory.DataBind() 
        
                    Catch ex As Exception 
        
                        ' your error catching protocol 
        
                    Finally 
        
                    End Try 
        
                End Sub

4. Call the method -- passing in whether you want the current or earlier version. The example below gets a different version

    
            ' pulls in different version 
        
            GetInventoryData("diffVersion")
