Ordinarily, if I hide/show an element containing a RadGridView, when I show it the first time, it takes around a half second to initialize, but when I show it a second time it appears almost instantaneously.

Unless I put it in a Popup, as I discovered when trying to implement a ComboBox-like UserControl.  Then it initializes every time the Popup is displayed.  The RadGridView in this example is bound to a collection containing three strings, and it takes about a half second to display every time I click on the ToggleButton:


Is there something I can do to get around this?  I'd really like to avoid having to go back to using a ListView in my control.

Thanks,

Hello there,

another feature item I just came across is 'custom styles', as predefined styles (known from Word (font/size/color, indentation, bullet list (if applicable), margins etc), defined & stored/loaded in/from the doc upon saving/loading) which doesn't seem to be supported at the moment.

Is this feature planned?

All the best,

So i have points Data that have two members YValue and Axis Label.
i have multiple series. for each series i set the mapping as such

seriesmapping.SeriesDefinition = GetSeriesType(series.SeriesType);// right now all are line charts
            seriesmapping.CollectionIndex =index;
    ItemMapping itemMapping = new ItemMapping();
            itemMapping.DataPointMember = DataPointMember.YValue;
            itemMapping.FieldName = "YValue";
            return itemMapping;
    seriesmapping.ItemMappings.Add(ItemMapping);

Now for the labels i am taking the following approach. i tried keeping this binding for only the first series. then bind to every series
//ItemMapping itemMapping = new ItemMapping();
                //itemMapping.DataPointMember = DataPointMember.Label;// i tried both this and X category
                //itemMapping.FieldName = "AxisLabel";
                //seriesmapping.ItemMappings.Add(itemMapping);

with one series the labels work (i have other issues but they are mentioned in my last question). but adding multiple series and trying to bind the labels it does not work . what am i doing wrong.

Also. i dont want display certain points. these points i have as NAN. but you guys graph that and makes my graph look awful. is there anyway i can not display NAN.

I am use the RadChart in a CustomControl which used to work in the 2009 version of the control. Now that I have upgraded the controls to the 2010 Q3 SP1 version the control no longer works.

The problem is that - looking in snoop - the control has no visual tree. I have reduced the generic style to the following;

<Style TargetType="{x:Type asc:CustomControl1}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type asc:CustomControl1}">
                    <Grid>
                        
                        <Grid.Background>
                            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"  >
                                <GradientStop Color="#FFDCE7FD" Offset="1"/>
                                <GradientStop Color="#FF898AAC" Offset="0"/>
                            </LinearGradientBrush>
                        </Grid.Background>
                        
                        <telerik:RadChart x:Name="PART_AscChart" />

                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

    </Style>

The piece which I believe causes the problem is that the assemblies are loaded through a custom assembly loader at runtime, so I suspect that the generic style for RadChart is not being located.

Any ideas would be appreciated.

Thanks

Hi Geeks :)

I faced with the same issue, but my scenario is little bit different from the author of this post.

Steps to reproduce:

1. Click "add new item" in the grid.
2. Press "Escape" button (Once), to still have the item in the grid.
3. Click on the header of the column, the "add new item" control will appears.
4. Click on it ("add new item")

Result: The crash will appears.

In attachment you will find all the mentioned steps in graphical example.

Thx,
Julian Ust.

Hi,

Is it possible to have a grid that allows users to add new items (through programatically calling BeginInsert) whilst preventing the user from editing existing items?

Thanks

I'm using the Docking example you provided with RadControls_for_WPF40_2010_3_1314.

If I want to dock a panel in the SolutionExplorer pane the corresponding compass is shown outside of the main window and disappears if I move the mouse cursor toward it. See attached screen shot.

I think this is a bug. When will it be fixed?

I'm trying to get validation working with the RadMaskedTextBox, I have found a few posts and an old example in your online help http://www.telerik.com/help/wpf/radmaskedinput-features-validation.html

The current help for the RadMaskedTextBox doesn't even talk about validation.

What I would like to do is have the outline around the RadMaskedTextBox turn red when something is wrong the data entered into the textbox.

Could you please send me a small example of this ?

Is there an easy way to select current date and time using the control or I should make such button myself?
