Hello,

I have a sparkline in a time bar, and I am looking to match the x values of the sparkline with the times of the timebar.  Currently, the first item in the sparkline is always shown at the start of the timebar, no matter if the times match or not.  Is there a way I can do this?

Thanks,
Eric

Whenever I type into a MaskedTextInput the words have a space.   Whenever the box loses focuses the spaces are truncated and the resultant combined single phrase is left in the box.  Once that box gains the focus again the phrase is broken out into its separate words again.  Is there a to prevent this from happening and have it not truncate the spaces whenever the boxes don't have focus?

Also, I can't seem to get the boxes character limit past 20 some odd characters.  Is there a way to increase that limit?

Thanks for any help.

Hello,

i created any GridViewComboBoxColumns on code behind with:


        private void MyGridView_AutoGeneratingColumn(object sender, Telerik.Windows.Controls.GridViewAutoGeneratingColumnEventArgs e)
        {
            DirInfoPropertyDescriptor propertyDecriptor = e.ItemPropertyInfo.Descriptor as DirInfoPropertyDescriptor;
            GridViewDataColumn datacolumn = e.Column as GridViewDataColumn;
            if (datacolumn != null)
            {
                IList<FieldDropDownItem> dropdownItems = DirInfo.FieldsDropdownItemsCache[propertyDecriptor.Name];
                if(dropdownItems.Count != 0)
                {
                    GridViewComboBoxColumn comboColumn = new GridViewComboBoxColumn();
                    comboColumn.Header = datacolumn.Header;
                    comboColumn.DataMemberBinding = datacolumn.DataMemberBinding;
                    comboColumn.SelectedValueMemberPath = "Id";
                    comboColumn.DisplayMemberPath = "Description";
                    comboColumn.SortMemberPath = "Description";
                    comboColumn.ItemsSource = dropdownItems;
                    (sender as RadGridView).Columns.Add(comboColumn);
                    e.Cancel = true;
                }                    
            }           
        }

It works nice: i can see and edit my dropdown values, but i cant sort.
After sorting my grid is empty, see screenshot

I am upgrading from Q3 2011 to Q2 2012 and ran into a problem with the numeric input.  I cannot enter a negative value into my textboxes.  It doesn't throw an error - it just ignores the negative sign.  I have tried the number pad and the regular keyboard and I have tried entering the negative first and entering it last.  Nothing seems to work.
See below for an example of one of the text boxes.  I checked the value in the validator and it is positive there so it isn't the validator changing the value.

<telerik:GridViewDataColumn DataMemberBinding="{Binding Units}" DataFormatString="{}{0:f2}" IsFilterable="False" Width="80"
                                            IsReadOnlyBinding="{Binding HideUnits}">
                    <telerik:GridViewDataColumn.Header>
                        <TextBlock Text="Units" TextWrapping="Wrap" />
                    </telerik:GridViewDataColumn.Header>
                    <telerik:GridViewDataColumn.CellEditTemplate>
                        <DataTemplate>                                                      
                            <telerikInput:RadMaskedNumericInput x:Name="txtUnits" Mask="#9.2"
                                                                SpinMode="None" IsClearButtonVisible="False" SelectionOnFocus="SelectAll"
                                                                KeyboardNavigation.TabNavigation="Local" TextMode="PlainText"                                                               
                                                                Validation.ErrorTemplate="{StaticResource TextBoxErrorTemplate}" 
                                                                 >
                                <telerikInput:RadMaskedNumericInput.Value>
                                    <Binding Path="Units" Mode="TwoWay" UpdateSourceTrigger="LostFocus">
                                        <Binding.ValidationRules>
                                            <imKASHelper:DoubleValidationRule Min="-100000000.00" Max="100000000.00" />
                                        </Binding.ValidationRules>
                                    </Binding>
                                </telerikInput:RadMaskedNumericInput.Value>
                            </telerikInput:RadMaskedNumericInput>
 
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellEditTemplate>
                </telerik:GridViewDataColumn>

My boss just showed this to me, though it's been in the application for a while.  If a user double clicks on the divider between columns in the column header on this one RadGridView control in my app, the following exception is thrown:

2012-07-18 09:11:18,106 [1] FATAL CarSystem.App [(null)] -  Invalid value!

                     SelectionUnit="FullRow"
                     ScrollViewer.CanContentScroll="True"
                     ScrollViewer.HorizontalScrollBarVisibility="Auto"
                     ScrollViewer.VerticalScrollBarVisibility="Auto"
                     ToolTip="Matching Hot List Entries">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Plate,        Mode=OneWay}"
                                    Header="Plate"
                                    Width="1.5*" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding LocaleCode, Mode=OneWay}"
                                    Header="State"
                                    Width="75" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding ListName,   Mode=OneWay}"
                                    Header="Hot List"
                                    Width="150" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding AlarmClass, Mode=OneWay}"
                                    Header="Alarm Class"
                                    Width="175" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Notes,     Mode=OneWay}"
                                    Header="Notes"
                                    Width="1*" />
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

With some experimenting, I've found that the exception is thrown only if you click on those columns that contain "*" in their Widths.  if you set it to Auto or a fixed value, it doesn't happen.

Hi,

I have a code similar to this:

        RadWindow.Confirm("Are you sure?", AddressOf OnClosed)
MessageBox ("Hi World")        

The alert or message always show it....regardless of response, in fact is an immediate action.

Is there a way that predefined windows you can wait for confirmation or selection by the user?

Something like Windows Desktop. NET:

If (message) = vbYes Then
MessageBox ("Hi World")     
End If

In advance, thank you all.

Hi,

When the QuickAccessToolbar of the RadRibbonView has many items added to it, not all items are visible or accessible.  Is there a way to cause the QuickAccessToolbar to grow in size (i.e. double in size)?  Or is there a way to automatically add items that are not visible to overflow?

Thanks,
Trang

Hi,  Is there a way to set the DataFormDataField so that the TextBox has a MaxWidth, and the Label width stretches to cover the rest of the width of the DataField?

I'm trying to create a form where the responses will all be numeric (so the TextBox doesn't need to stretch to Infinity), but the length of the label varies wildly (ergo, does need to stretch).  The labels on my DataFormDataFields are being cut off to allow the TextBox (plus spacing) to have more room.  If I increase the width of the DataField, this increases the amount of space between the TextBox and the Label. 

I've played with the Width of the DataField, the Min, Max & Width of the DataField.Label, the Width of TextBoxes, all to no joy.  Similar results messing with HorizontalAlignment, HorizontalContentAlignment, and even ZIndex (I thought I could bring the label above the text box).

Thanks for any ideas, I'm at the stage where I'm about to start coding a Label + TextBox in a Stackpanel solution for each of my datafields, and I'd _really_ prefer not to.  

Also (coz I think it's relevant but I'm not sure), I don't have Expression Blend.

cheers

Alex

Hi,

pCarousel.BringDataItemIntoView(pCarousel.Items[0]);

to have the first page ont top. The 2nd page in my carousel sill white (empty) until I scroll the 2nd page ouside the carousel view and bring it back into th carousel view, at this time I can see the 2nd page content.

Thank's
