Hi -

My goal is to have a selection of one ComboBox populate a Selection in another ComboBox.
Example... Box 1 selection is Food, Box 2 selection would then have a collection of Food Items like cheese, bread or soda.

Here is my code:

    
                    RadPanelItem ProjectSearchItem = (RadPanelItem)RadPanelBar1.FindItemByValue("ProjectSearch");  
        
                    RadComboBox projectGroupRadComboBox = (RadComboBox)ProjectSearchItem.FindControl("projectGroupRadComboBox");  
        
                    IQueryable allProjectGroup = ProjectGroup.GetAllBindings();  
        
                    projectGroupRadComboBox.DataSource = allProjectGroup;  
        
                    projectGroupRadComboBox.DataValueField = "ID";  
        
                    projectGroupRadComboBox.DataTextField = "Name";  
        
                    projectGroupRadComboBox.DataBind();  
        
                    projectGroupRadComboBox.Filter = RadComboBoxFilter.Contains;  
        
                    if (projectGroupRadComboBox.SelectedValue != null && projectGroupRadComboBox.SelectedValue.Length > 0)  
        
                    {  
        
                      projectGroup = ProjectGroup.Get(Convert.ToInt32(projectGroupRadComboBox.SelectedValue));  
        
                      RadComboBox projectNameRadComboBox = (RadComboBox)ProjectSearchItem.FindControl("projectNameRadComboBox");  
        
                      IQueryable allProjectName = Project.GetAllBindings(projectGroup.DataModel.ID);  
        
                      projectNameRadComboBox.DataSource = allProjectName;  
        
                      projectNameRadComboBox.DataValueField = "ID";  
        
                      projectNameRadComboBox.DataTextField = "Name";  
        
                      projectNameRadComboBox.DataBind();  
        
                      projectNameRadComboBox.Filter = RadComboBoxFilter.Contains;  
        
                    }  
        
                    else 
        
                    {  
        
                      RadComboBox projectNameRadComboBox = (RadComboBox)ProjectSearchItem.FindControl("projectNameRadComboBox");  
        
                      IQueryable allProjectName = Project.GetAllBindings(null);  
        
                      projectNameRadComboBox.DataSource = allProjectName;  
        
                      projectNameRadComboBox.DataValueField = "ID";  
        
                      projectNameRadComboBox.DataTextField = "Name";  
        
                      projectNameRadComboBox.DataBind();  
        
                      projectNameRadComboBox.Filter = RadComboBoxFilter.Contains;  
        
                    }

The if statement and next line contain my problem.

I am used to using .SelectedValue with DDLs to select the Value, but with ComboBoxes it is not working. What do I use in place of .SelectedValue, or is it more complicated than that? I have read other posts pertaining to this and don't know which direction to take.

Thanks!!

Simulating 'filter' call from asp:button

I'm using Visual Studio 2005 with the latest Telerik RadGrid component. We have disabled the AutoPostBack on the filter field and used JavaScript to intercept and stop the filter call made by the filter menu click. However we can find no way to then have a button on the page that then simulates the same call. Our attempts just won't work because the postback loses the filter details and when interrogating the grid filter values in the code-behind the select filter item is 'No Filter'.

Scenario:

1. Enter various filter values in columns and select the filter type from menu.

2. Click button that's posts back this detail and allows us to construct SQL to query on all column values.

We have tried a variety of options none of which seems to work (in VS2005 at least), can anyone point us in the right direction? Preferably with a detailed code example? You're help would be greatly appreciated!

Binding to objects

Hi,

I am working on an application generator and I need to code generic "browse" pages that automatically populate a grid with all instances of a given type. Everything in my application is object driven so I use an ObjectDataSource.

Problem : I need to bind some columns to property types that are not on the bindable type list... When the type is not bindable I just need to display the result of the ToSTring() method.

How can I do that ??

Thanks in advance,
Laurent.

How do we adjust the Splitter Tab text size?

http://demos.telerik.com/aspnet-ajax/splitter/examples/sp_tabview/defaultcs.aspx

We don't appear to have control of the text size nor the text fore color inside the Splitter Tabs. Is it because it's formatted inside of a skin? Can we access the text formatting options for the Splitter Tabs elsewhere?

We've tried many seemingly logical methods, all to no avail.

Thanks for any help you can offer because the text is too small for our particular application.

DataBinding event handler not called for control in Template column

Hi,

I have a custom control type that implements ITemplate and is added to a GridTemplateColumn. I have added an event handler to the literal control that is part of the custom control.

    
                    public void InstantiateIn(System.Web.UI.Control container) 
        
                    { 
        
                        System.Web.UI.LiteralControl c = new System.Web.UI.LiteralControl(); 
        
                        c.DataBinding += new EventHandler(Button_DataBinding);

The first time the page loads, the event handler gets called. However, on Postback the event handler is not called.

Any ideas?

Thanks,
Dewang

Problems with DockPositionChanged

The setup we have is this: we have a DockZone filled with collapsed docks that the user drags out to one of three main dockZones on the page. When the dock is dropped into the new zone we are firing the DockPositionChanged event. This event flushes out the dock with all of the controls that it needs and loads the usercontrol into the dock. What we are seeing is whenever any event is triggered, the usercontrol inside the dock does an asynpostback or the expandCollapse event is fired so to is the DockPositionChanged event. Also we would really want the master list per say of docks to be repopulated with a fresh copy of the dock that was just dragged out and placed into one of the three zones.

CODE:

This is the master page that has the RadDockLayout

                    <asp:UpdatePanel ID="upl_Content" runat="server" UpdateMode="Conditional" >         
               <ContentTemplate>         
                  <telerik:RadDockLayout ID="RadDockLayout_Content" runat="server" onloaddocklayout="LoadDockLayout" onsavedocklayout="SaveDockLayout">           
                     <asp:ContentPlaceHolder ID="ContentPlaceHolderContent" runat="server"></asp:ContentPlaceHolder>         
                  </telerik:RadDockLayout>          
               </ContentTemplate>           
            <Triggers>         
            </Triggers>         
            </asp:UpdatePanel>         

Next we build the dockzone with all the available docks

                    protected void Page_Init(object sender, EventArgs e)         
            {         
                GetWidgets();         
            }         
                     

                            private void GetWidgets()         
                    // POPULATE WIDGET SELECTION ZONE         
                    {         
                        if (WidgetList.Controls.Count == 0)         
                        {         
                            ArrayList _wigetArray = new ArrayList();         
                            _wigetArray.Add("~/Prototype/Modules/CriticalPrinters/CriticalPrinters.ascx");         
                            _wigetArray.Add("~/Prototype/Modules/CriticalPrinters/CriticalPrinters.ascx");         
                            _wigetArray.Add("~/Prototype/Modules/SMIncidentAge/Services/SMIncidentAge.ascx");         
                            _wigetArray.Add("~/Prototype/Modules/Weather/WeatherControl.ascx");         
                     
                            int i = 0;         
                            foreach (String widgetURL in _wigetArray)         
                            {         
                                NCSBlackRadDock dock = new NCSBlackRadDock();         
                                dock.widgetIcon.ImageUrl = "~/Prototype/Modules/HttpWebRequest/Images/Config.png";         
                                dock.WidgetTitle.Text = string.Format("RadDock{0}", i);         
                                dock.Tag = widgetURL;         
                                dock.ID = string.Format("RadDock{0}", i);         
                                dock.UniqueName = Guid.NewGuid().ToString();         
                                dock.Text = dock.ID.ToString();         
                                dock.statusPanel.Visible = false;         
                                dock.widgetPanel.Visible = false;         
                                dock.EnableViewState = false;         
                                dock.Commands.Remove(dock.CloseCommand);         
                                dock.Commands.Remove(dock.ExpandCommand);         
                                dock.Commands.Remove(dock.SettingsCommand);         
                     
                     
                                dock.DockPositionChanged += new DockPositionChangedEventHandler(RadDock_DockPositionChanged);         
                                dock.AutoPostBack = true;         
                                dock.Collapsed = true;         
                     
                                WidgetList.Controls.Add(dock);         
                                i++;         
                            }         
                        }         
                    }         

Then finally the RadDock_DockPositionChanged

                            protected void RadDock_DockPositionChanged(object sender, DockPositionChangedEventArgs e)         
                    {         
                                 
                        Site1 pm = (Site1)Page.Master.Master;         
                        NCSBlackRadDock dock = (NCSBlackRadDock)sender;         
                     
                        if (dock.DockZoneID != e.DockZoneID)         
                        {         
                            try         
                            {         
                                dock.DockZoneID = e.DockZoneID;         
                                dock.Collapsed = false;         
                                dock.statusPanel.Visible = true;         
                                dock.widgetPanel.Visible = true;         
                                DockCloseCommand _CloseCommand = new DockCloseCommand();         
                                DockExpandCollapseCommand _ExpandCommand = new DockExpandCollapseCommand();         
                                dock.Commands.Add(_CloseCommand);         
                                dock.Commands.Add(_ExpandCommand);         
                                dock.Commands.Remove(dock.PreviewCommand);

                            catch { }

Images always go at the top of the content placeholder

We've found when we use the image manager to add an image into the content placeholder in the middle of other text, the image is always inserted at the top of the HTML, and you have to drag it down manually to the correct place. Is this standard behaviour - is there any way to get the images to insert at the cursor position rather than right at the top?

Image preview different in browsers

Hi,

In FF and IE there is a major difference when double clicking on an image.

Please refer to the attached preview screenshots. I prefer the FF way.
