[Solved] Separate legends for multi pie-chart series?

Hi there,

Can somebody please advise re the following two questions on the RadChart control:

1. If I create one (Pie) radChart, then add two series to it, I get two separate pie charts - great.
However, the two legends for these separate charts are "mixed", that is, they appear in one block. Is it possible to have a separate legend for each pie chart/series?
The legends are created using the following line:
radChart1.Series[0].Appearance.LegendDisplayMode = Telerik.Charting.ChartSeriesLegendDisplayMode.ItemLabels;

2. What setting controls the colour of the number associated with the item, that is, the number appearing beside the pie chart slices showing the data for that segment? Is is taken from one of the background or border colours, or can it be controlled invididually?

Thanks a lot - excellent product by the way,

Charles

Radlistbox get and set selected items

Hi,

I need to select/deselect items from one listbox to another.
For that I am using two radlistboxes, both are having same items. Both listbox's selectionmode="Multiple".

When user selects items in first list, I need to select them in second listbox through Javascript.
For that, I tried some code, but it works for single item only.

    
                       var ctl1= $find('<%= lstTestcategory2.Clientid %>'); 
        
                          var ctl= $find('<%= lstTestcategory.Clientid %>'); 
        
                for(var i = 0; i<= ctl.get_items().get_count()-1; i++)   
        
                {  
        
                      var item1 = ctl.get_items().getItem(i);    
        
                       alert(item1.get_text());  
        
                      alert(item1.get_selected()); 
        
                         check = 1;  
        
                  for(var i = 0; i<= ctl1.get_items().get_count()-1; i++)   
        
                    {  
        
                  //     alert('in');  
        
                            var item = ctl1.get_items().getItem(i);       
        
                            if(item.get_text() == e.get_item().get_text())  
        
                            {  
        
                       //    alert('in1');   
        
                                item.set_selected(true); 
        
                                check = 1;  
        
                            }  
        
                           else 
        
                           { 
        
                              item.set_selected(false); 
        
                            } 
        
                    }

At present I am using it on "OnClientSelectedIndexChanging" event.

What should I do to work it for multiple items too?

Editing behaviour like ASP.NET Grid

I am very impressed with using RadGridView in ASP.NET that when I click "edit" button on the Grid record, a templateform is shown and users can input and save data.

But how this kind of features handled in Telerik WinForm GridView? Or in WinForm GridView only provides Grid presentation or editing on the grid record?

My requiement:
1. click "add" or "edit" buttons, show a editing form (because need to process many fields, using a form format is better)
2. click "ok" or "cancel" buttons back to the grid and grid may need to be refreshed.

Benson.

Blank Row on databound combobox

How can I have my combobox display nothing when my form loads? Currently when it loads it shows an item from the table it is bound too. I want the combobox to be blank/empty then the user can select what to pick. Currently there is only 1 item in the combobox. Does that have any effect? I tried to edit the combo and add a blank item but it is in the drop down but not selected.

Thank You

Wrap Text In Column....HOW?!

All I want to do is have a paragraph of text in a cell wrap. Why is this so hard with your grid control. Never before have I had so much trouble. I see the properties and options there (wordwrap, colwidth, rowheight, etc. etc. etc.). No matter what I do, nothing wraps.

sort 2 columns in radgridview

i have a rad gridview and i want to set the sorting of it by 2 columns.

What i mean is when i sort one column, the result will also depend to the other column..

example:

Column 1 | Column 2 | Column 3
1                    1                ABC
1                    1               ADE
2                    1                ZZS

When i sort column 3, column 1 will also be sorted
Column 1 | Column 2 | Column 3
2                    1                ZZS
1                    1               ADE
1                    1                ABC

Is that possible?

this is for winforms in C#.net

Many Thanks
