Hi

I am currently evaluating your GridView control and I would like to know if it supports lookup columns when data bound.

Just to clarify I want to, for example, bind a grid to the Northwind orders table and have the EmployeeID column show the LastName from the Employees table rather than the EmployeeID.

Regards, Carl Gilbert

Listbox extremly slow loading

I list by business objects in a listbox. It find it extremly slow to load.
Here is my code:

                    Dim lngTick As Long = Environment.TickCount  

                    lbxPromotionProduct.BeginUpdate()  

                    Dim prods As ProductROCollection = ProductROCollection.GetProductsRO(_identity.CompanyId)  

                    Debug.WriteLine("Time to Load collection" & vbTab & Environment.TickCount - lngTick)  

                    lngTick = Environment.TickCount  

                    If prods.Count > 0 Then 

                        If optPromotionProductListByName.Checked Then 

                            prods.SortStable("productName", System.ComponentModel.ListSortDirection.Ascending)  

                        Else 

                            prods.SortStable("productRef", System.ComponentModel.ListSortDirection.Ascending)  

                        End If 

                    End If 

                    Debug.WriteLine("Time to SortStable" & vbTab & Environment.TickCount - lngTick)  

                    lngTick = Environment.TickCount  

                    With lbxPromotionProduct  

                        .DataSource = Nothing 

                        .DisplayMember = "productRefName" 

                        .ValueMember = "productRef" 

                        .DataSource = prods  

                        Debug.WriteLine("Time to DataSource" & vbTab & Environment.TickCount - lngTick)  

                        lngTick = Environment.TickCount  

                        If .SelectedIndex > -1 Then .SetSelected(.SelectedIndex, False)  

                        Debug.WriteLine("Time to Selected" & vbTab & Environment.TickCount - lngTick)  

                        lngTick = Environment.TickCount  

                    End With 

                    lbxPromotionProduct.EndUpdate()  

                    Debug.WriteLine("Time to EndUpdate" & vbTab & Environment.TickCount - lngTick)

and the output is:

Time to Load collection 501  

Time to SortStable  110  

Time to DataSource  6820  

Time to Selected    0  

Time to EndUpdate   2213

We are only talking about 584 records so it's not a huge amont of data.

Any advice?

Event Handler on dynamic RadButtonElements

Hi,

I'm dynamically populating a RadPanelBar with a series of GroupElements and RadButtonElements. I'd like to know how I can add an onClick handler to each generated RadButtonElement so that I can get the dyncamically generated buttons to perform some function.

I've done similar code with Menu Items which allow an OnClick eventHandler as a parameter when you add items to the Menu;

ReportMenu.MenuItems(f).MenuItems(g).Add("Report X"), New System.EventHandler(AddressOf openReport_Click)) 

Any ideas how I can get this all happening?

Cheers,
Karin

how to add arrow in the radButtonElement

Hi ,

I am using RadPanelBar and I have 2 RadButtonElement inside RadpanelBarGroupElement. I need to have an arrow pointer ( pointing to the right ) of the button whenever the user moves its mouse over it. This will help user to know which form is chosen on the right from these RadButtonElement.
As an example:
Please see any menu items that has arrow buttons on it when it contains submenus.
I want the arrow to appear on the RadButtonelement only when its selected and the respective details are shown on the right side of the form.

Any help on this is appreciated.

Thanks
barkha

Not able to apply the theme in PanelBar

Hi All,

I have a radPanelBar control in my form and by default it has blue color on it group elements and while on the content layout. Also when mouse moves the group button item elements, they highlight as yellow.

I created theme using RadPanel Tasks bar and "Open Theme Builder" to create a new theme and then saved the xml file at the Resources folder and set the compile option to the Embedded Resource.

After this I ran the application but didn't see any chane in the colors of the control.

Can someone please tell me where I am wrong?

Is there any way to send you the sample application that I am trying?

Thanks
barkha

Pinning an auto hidden DockPanel

I have a DockingManger that has two DockPanels setup at design time.
One of the DockPanels I want to allow auto hiding and pinning, the other not. This works just fine, but I also do not want to allow other potential DockPanels to be docked to this DockingManger. To do so I set the AllowDocking property on the DockingManger to false.

Unfortunately a side effect of doing so prevents an auto hidden DockPanel from being re-pinned.

Is there a way around this?

restore controlls into docking manager

hi,

i wanted to restore all elements into my docking manaer, i could not use this solution as i do not know how many panells i will have and what kind of usercontorlls they will host , i do not want to make if/then for each control deserialization so I wrot this code, which uses aditional xml file to store data about controls stored in panels, and than it uses reflection to reinitilize it

private void SaveLayout()

{

dockingManager1.SaveXML(fileName);

XmlDocument doc = new XmlDocument();

XmlElement root = doc.CreateElement("SerializedControlCollection");

doc.AppendChild(root);

//go through the sites

foreach (IDockingSite site in dockingManager1.DockingSites)

{

//now get panels

foreach (DockPanel pan in site.ManagedDockables)

{

//check if there is anything in panel

if (pan.Controls.Count > 0)

{

//get first child of panel, this one is interesting for me

UserControl userControl = pan.Controls[0] as UserControl;

//check if this is user control

if (userControl != null)

{

XmlElement contElement = doc.CreateElement("Control");

XmlAttribute att = doc.CreateAttribute("DockableGuid");

contElement.Attributes.Append(att);

att.InnerText = pan.ID.ToString();

contElement.InnerText = userControl.GetType().FullName;

root.AppendChild(contElement);

}

doc.Save(controlFile);

}

private void RestoreLayout()

{

if (File.Exists(fileName))

{

dockingManager1.LoadXML(fileName);

}

XmlDataDocument controlInfo = new XmlDataDocument();

controlInfo.Load(controlFile);

//create hashtable to make it easier later

Dictionary<string, string> idToTypeMap=new Dictionary<string, string>();

foreach (XmlElement el in controlInfo.FirstChild.ChildNodes)

{

string guid = el.GetAttribute("DockableGuid");

idToTypeMap[guid] = el.InnerText;

}

//restore contorls inside

foreach (IDockingSite site in dockingManager1.DockingSites)

{

//now get panels

foreach (DockPanel pan in site.ManagedDockables)

{

if(idToTypeMap.ContainsKey(pan.ID.ToString()))

{

string typeName = idToTypeMap[pan.ID.ToString()];

Type t = this.GetType().Assembly.GetType(typeName);

Control con = (Control) Activator.CreateInstance(t);

pan.Controls.Add(con);

}

remove dockable panel & save

I have a problem with removing dockable elements from panel, i registred a eventhandler and I call
//pan.DockingSite.Remove(pan);
dckingManager1.PrimarySite.Remove(pan);

//dockingManager1.RemoveDocument(pan);

and than I call SaveLayout, but after loading panel is still there, if i however add a new dockable and save it it will persist .
in examples it is only possible to remove all nodes or add new nodes, so i can not see how (and if this can be implemented)

what i have to do to remove panel and save layout without thid panel ?
thanks
