Radgrid Polymorphism, Griditem, GridDataItem

I've been using event handlers to do some custom formatting, or calculations within grids for a while. I will usually write something like so, that accesses the TableCells by UniqueName:

void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {
            GridDataItem item = e.Item as GridDataItem;
            if (item != null)
            {
                Do some work
                ....
                        item["ColName"].text = ...;
                .....

            }
           GridFooterItem item = e.Item as GridFooterItem;
            if (item != null)
            {
                Do the same work
                ....
                        item["ColName"].text = ...;
                .....

            }
        }
To prevent code duplication, is there anyway i can use a base class or interface member to reference the TableCells by name?

Set Radiobuttonlist value on insert

I have tried the links to setting values for bound items in a edit/insert form template but cannot get it to work. I have a radiobuttonlist in my custom edit form and when I try to insert a new record I get the

'RadioButtonList1' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
error.

This radiobuttionlist is bound to a sql data field called "publishgroup" to get its selected value however I have tried and tried to set the selected value on insert but cannot get it set. Can you provide a code sample to find the control and set the value when I go into insert mode.

Thanks

finding controls in radtoolbar items

I have a combox inside a itemtemplate for a RadToolBarButton. Once I have buried the control in the itemTemplate, I can no longer access it in code behind. Is that correct? So the only way I can access the control is to do something similar to:

RadComboBox cmbPresets = (RadComboBox)rtbMenuAdmin.FindItemByText("Preset").FindControl("cmbPresets");

Thanks!

Event Calendar?

Has anyone worked the Calendar into a Event Calendar that a website owner can input event info into, via Scheduler perhaps, and that the site viewer can click on to view event information? I don't find any demos of the Calendar that is being used in this way.

Persist treeview state with static nav links

Hello,
I'm attempting to use a radTreeView for navigation in a Master page. Each link navigates to a content page. The items are static in the html code, not loaded at runtime. I can't seem to save the state between pages. I'm using the code below, I didn't paste in the entire tree. Can someone point me in the right direction.

    
            telerik:RadTreeView ID="RadTreeView1" Runat="server"   
        
                                EnableAjaxSkinRendering="False" ShowLineImages="False"   
        
                                SingleExpandPath="True"  EnableEmbeddedSkins="False" 
        
                                Skin="MySkin" OnClientNodeClicked="ClientNodeClicked" OnNodeExpand="RadTreeView1_NodeExpand"   
        
                        onnodecollapse="RadTreeView1_NodeCollapse">

    
            protected void Page_Load(object sender, EventArgs e)  
        
                {  
        
                    if (!Page.IsPostBack && String.IsNullOrEmpty((string)Session["myTreeView"]))  
        
                    {  
        
                        Session["myTreeView"] = RadTreeView1.GetXml();  
        
                    }  
        
                    else if (!String.IsNullOrEmpty((string)Session["myTreeView"]) && (!IsPostBack))  
        
                    {  
        
                        string treeViewState = (string)Session["myTreeView"];  
        
                        RadTreeView1.LoadXmlString(treeViewState);    
        
                    }  
        
                }  
        
            protected void RadTreeView1_NodeExpand(object sender, RadTreeNodeEventArgs e)  
        
                {  
        
                    Session["myTreeView"] = RadTreeView1.GetXml();  
        
                }

I am using node templates with links if it makes a difference.

    
            <telerik:RadTreeNode runat="server"   
        
                                        HoveredImageUrl="~/images/plus.jpg"    
        
                                        ImageUrl="~/images/node-image.gif" Width="165px" > 
        
                                         <NodeTemplate> 
        
                                              <a href="ContactUs.aspx">Contact Us</a> 
        
                                            </NodeTemplate> 
        
                                    </telerik:RadTreeNode>

RadMenu Items Shifted

I am building an ASP.NET website with various Telerik controls using .NET 3.5 and Telerik RadControls_for_ASP.NET_AJAX_2010_1_309_dev.msi. When I expand the detail records for a row in a RadGrid, I am seeing some odd behavior with the RadMenu...in particular, the menu items shift to the right slightly:

Menus OK

Menus after viewing details in RadGrid

In my masterpage I have a RadMenu that is common to all pages:

    
                                    <telerik:RadMenu ID="RadMenu1" runat="server" Skin="Office2007" Width="100%">

[Solved] Control Paging look in header/footer

Hi,

I'm trying to customize the look of the pager. I know I can create a pager template and set up custom look at feel with that. The problem is that when you set the paging position to Top And Bottom it is exactly the same. We are looking to have the top with some custom look/feel and the bottom to have a different look/feel. I have not created the custom paging yet. One solution would be for me to find a way to detect if the controls are in the header/footer pager and set visibility based on that. Is this possible, or can I get a code snippet of how this can be done? I attached a file to give an example of how we are planning to do our custom paging in the header and footer. We have paging in the footer and we have setting the page size information in the header.

    
            <telerik:RadGrid AutoGenerateColumns="false" ID="rgPermissions" DataSourceID="odsUserPermissionsTypes" 
        
                        AllowFilteringByColumn="True" AllowSorting="True" ShowStatusBar="true"   
        
                        AllowPaging="True" runat="server" GridLines="None"   
        
                        onitemdatabound="rgPermissions_ItemDataBound" > 
        
                        <PagerStyle Mode="NextPrevAndNumeric" Position="TopAndBottom" /> 
        
                        <GroupingSettings CaseSensitive="false" /> 
        
                        <MasterTableView AutoGenerateColumns="false" AllowFilteringByColumn="True" ShowFooter="True" TableLayout="Auto">  
        
                            <Columns>
