Hi,

Let say I have few items in my radcombobox

Item2 ---> Selected
Item3

New Input value: Item 3
On Submit -- Must select Item 3..
But Item2 remain selected

foreach

(RadComboBoxItem item in rdCboStaff.Items)

{

if (newvalue == item.Value)

item.Selected =

true;

}

What is missing here?

Thanks

Change radGrid columns header

I'd like to programmatically change the radgrid column header (depending on user culture). In my database I have the translation of words to use for each column uniquename.
To do the translation I use the radgrid_columncreated event.

    
                protected void RadGridTraduzione_ColumnCreated(object sender, GridColumnCreatedEventArgs e)  
        
                {  
        
                    string c = e.Column.UniqueName;  
        
                    GridColumn boundColumn = e.Column as GridColumn;   
        
                    if (boundColumn.UniqueName == "Maschera")  
        
                    {  
        
                        switch (((SessionInformation)Session["sessionData"]).IdCultura)  
        
                        {  
        
                            case 1:  
        
                                //boundColumn.HeaderText = ...;  
        
                                break;  
        
                            case 2:  
        
                                //boundColumn.HeaderText = ...;  
        
                                break;  
        
                            case 3:  
        
                                break;  
        
                            case 4:  
        
                                break;  
        
                        }  
        
                    }  
        
                }

I have the problem that e.Column.UniqueName is "ExpandColumn" for all my bound data columns, how can I access the .aspx specified UniqueName?

[Solved] RadListBox CheckBox in ItemTemplate does not maintain state on postback

Hello,

I have a RadListBox which has a number of CheckBoxes and other controls in an ItemTemplate. Since migrating from 2009 Q3 to 2010 Q1, I've realized that the state of the CheckBoxes is no longer being maintained on PostBack.

Initially I created a small separate project to try and isolate the problem, but realised when I switch back to 2009 Q3, then the state is being maintained as expected.

Is this a known issue? Is there a work around?

Thanks,

David

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!
