another case that CellValidating is not fired

Hello,

Today, we found that if we changed the value of a cell in a grid first, then use mouse to click on the empty data area of that grid. The CellValidating event won't get fired. Currently, we found 3 cases that CellValidating event won't fire:

1. press ESC when editing

(sometimes the data loaded from db contains error. we need to check it even when user is aborting editing by press ESC)

2. click on the scroll bar when editing

3. cllick on the empty data area when editing

We need fixes to these very very quickly. Do you have any info when will these get fixed. Our customers continued to complain about these bugs and nothing we can do with this situation.

Thanks in advance.

ngen fails on WinForms build 1203

Hello,

since we have major performance problems with WinForms (esp. RibbonBar takes more than 10 seconds to load),
we tried to improve performance by precompiling the control with ngen.
This failed with the following message (Windows 7 x64):

Any idea, that is causing this error ?

Radgridview with CheckBox - CheckAll and UnCheckAll

Hi,

We are using Radgridview with CheckBox and also we have added the CheckAll and UnCheckAll button. We have finished this CheckAll and UnCheckAll functionalities using looping with grid.rows.count, but when we are filter the row it shows the total rows count and also getting the exception like 'Index 145 is either negative or above rows count.'. Refer the below code and kindly let me know how we have to solve this issue.

CheckAll:

for

(int i = 0; i < radGrid.Rows.Count; i++)

{

radGrid.Rows[i].Cells[

"-"].Value = Boolean.TrueString;

item = radGrid.Rows[i].DataBoundItem;

if (!this.selectedRows.Contains(item))

this.selectedRows.Add(item);

}

UnCheckAll:

this

.selectedRows.Clear();

for (int i = 0; i < radGrid.Rows.Count; i++)

{

radGrid.Rows[i].Cells[

"-"].Value = Boolean.FalseString;

}

[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?
