Get Grid Sort Column and Direction

I am currently working on a grid that is using the virtual scrolling, and I need to be able to determine, on post back, what the sort column and direction are. What properties of the radgrid can I use to get the current sort column and direction? I need to be able to access these values on post backs other than ones that fire the: RadGrid1_SortCommand event.

Something like:
if(IsPostBack)
{
string sSortColumn = RadGrid1.SortColumnName;
}

how do you return the column name?

Scrolling radbox clears selection

Hi, I have a strange behaviour in a scrolled radgrid, using server-side selection.

Markup:

    
            <telerik:RadGrid ID="rgCT" runat="server" Width="345" OnNeedDataSource="rgCT_NeedDataSource"

                            <EditItemStyle BackColor="#F7BD02" ForeColor="Black" /> 
        
                            <MasterTableView TableLayout="Fixed" CommandItemDisplay="None" DataKeyNames="CT_ID"> 
        
                                <Columns> 
        
                                    <telerik:GridTemplateColumn UniqueName="Selection" HeaderStyle-Width="10%"> 
        
                                        <ItemTemplate> 
        
                                            <asp:CheckBox ID="CheckBox1" OnCheckedChanged="ToggleRowSelection" AutoPostBack="True" 
        
                                                runat="server"></asp:CheckBox> 
        
                                        </ItemTemplate> 
        
                                    </telerik:GridTemplateColumn> 
        
                                    <telerik:GridBoundColumn UniqueName="CT_ID" DataField="CT_ID" Visible="false" /> 
        
                                    <telerik:GridBoundColumn UniqueName="CT_NAME" DataField="CT_NAME" HeaderText="CT" HeaderStyle-Width="89%"/> 
        
                                </Columns> 
        
                            </MasterTableView> 
        
                            <ClientSettings> 
        
                                <Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="True" 
        
                                           ScrollHeight="200px"  /> 
        
                            </ClientSettings> 
        
                        </telerik:RadGrid>

Code-behind:

    
                    protected void ToggleRowSelection(object sender, EventArgs e) 
        
                    { 
        
                        ((sender as CheckBox).Parent.Parent as GridItem).Selected = (sender as CheckBox).Checked; 
        
                    }

When I touch the vertical scrollbar (even if I don't really "scroll") the selection get cleared.
I see this in the onclick of a button, checking the SelectedIndexes.Count property of the Grid.
When I don't touch the scrollbar all selections are preserved, when I touch it the SelectedIndexes.Count is 0.

Any clue?

Thanks in advance for your help.

Filter Headings - 3 part Question

I have figured out how to hide the filter textbox for a column by doing the following:

    
            If TypeOf e.Item Is GridFilteringItem Then 
        
                        Dim filteringItem As GridFilteringItem = CType(e.Item, GridFilteringItem) 
        
                        'set dimensions for the filter textbox 
        
                        Dim box As TextBox = CType(filteringItem("CheckBoxTemplateColumn").Controls(0), TextBox) 
        
                        box.Visible = False

But...

1. how do I hide the filter icon that is next to each text box?

2. how can I add my own custom text in place of it if I want to?

3. how can I hide the filter options I do not want? for instance on a numeric column named "points" I only want "GreaterThan" and GreaterThanEqualTo".

Thanks!

[Solved] How to change ScriptDescriptors order?

Hi,

I create a web server control which contains a radGrid and radAjaxManager, in the same time I add some client capabilities to this web server control reference ASP.NET AJAX tutorials: Adding Client Capabilities to a Web Server Control
I add two client properties:

    
            protected virtual IEnumerable<ScriptDescriptor> GetScriptDescriptors() 
        
                    { 
        
                        ScriptControlDescriptor descriptor = new ScriptControlDescriptor("Unigestion.Web.UI.HTMLGrid", this.ClientID); 
        
                        descriptor.AddProperty("gridClientID", this._radGrid.ClientID); 
        
                        descriptor.AddProperty("ajaxManagerClientID", this._radAjaxManager.ClientID); 
        
                        return new ScriptDescriptor[] { descriptor }; 
        
                    }

And in the control's client script, I will get RadGrid and RadAjaxManager object:

    
            Unigestion.Web.UI.HTMLGrid.prototype = { 
        
                initialize: function() { 
        
                    this.$grid = $find(this.gridClientID); 
        
                    this.$ajax = $find(this.ajaxManagerClientID); 
        
                } 
        
            }

But when open this page, the client object's $grid and $ajax is null, I checked the page's source find that my control's descriptor js codes is before the radGrid and radAjaxManager:

    
            <script type="text/javascript"> 
        
            //<![CDATA[ 
        
            Sys.Application.initialize(); 
        
            Sys.Application.add_init(function() { 
        
                $create(Unigestion.Web.UI.HTMLGrid, {"ajaxManagerClientID":"AjaxManager","gridClientID":"innergrid"}, null, null, $get("radGrid")); 
        
            }); 
        
            Sys.Application.add_init(function() {

Prevent a default selection

What is the best way to ensure that there is no default selection in my combo box? I can clear it client side with:

    
                        var combo = $find("<%= RadComboBox1.ClientID %>");  
        
                        combo.clearSelection();

but I'd prefer to be able to clear it server side or even better just tell it not to select anything by default in the first place. I've tried the server side .ClearSelection() but I can't seem to get it to work. No matter where I call it (onload, after databind, etc) the first item in the list is still selected.
