hi

i am trying to develop with telerik,and i find this issue

example

there is some data in the gridview like 

id   name   birthday

1    lee    1984-01-01

2    chiang  2000-05-03

3    tom    1986-03-03

      jim    1996-12-01

i resort by name column then i get the table below

id   name   birthday
2    chiang  2000-05-03
      jim    1996-12-01
1    lee    1984-01-01
3    tom    1986-03-03

int index = -1;

foreach(gridviewrowinfo row in rows)

{

  if(row.cells["name"]=="lee")

    {index=row.index;}  //here we can get the index = 2

}

if(index>-1)

{

  rows[index].cells["birthday"]="1999-03-05";

}

then we get the table below:

id   name   birthday
2    chiang  2000-05-03
      jim    1996-12-01
1    lee    1984-01-01
3    tom    1999-03-05

have anyone get the mind that i mean?

when after the foreach we get a index after resorted and when we use rows[index] then the gridview point to the line before it is resorted!

so does it a bug?when will you fix it?

I am trying to style the gridview and I am running into an error which I can not figure out.

I have a 'templating' xaml and added and GridViewRow to it. Then in Blend i used RMB -> template -> Edit a copy.

which results in the following

If I now run my application it looks the same as before, In the grid a add a row that has validation errors. If I hover over the error indicator, I get an error saying it is missing 'xform'.

So I edited a part

Before:

After:

I no longer get the error in my application but the error tooltip is also not show. So there seems to be a problem with copying the template but I can not really figure out where it is.

Hi All

I have a WPF RadComboBox within a RadDataForm as per below - however whenever I press "insert" on my keyboard the data on the form disappears.   

I have tried to handle the "Insert" keypress in the keydown and keyup events but to no avail, it doesn't drop in there - I need to be prevent the form data from disappearing when the insert key is pressed.

Is there a way to disable a certain key from being pressed?

Please help ASAP.

Hi,

I'm attempting to find a way to only merge adjacent cells in specific columns. For example if I have a RadGridView with a few columns and I want to Merge similar values that are adjacent to each other in Column[0] how would I do this?

I understand that the RadGridView.Merge* properties don't cover this specific use case but is there an event I could handle that would let me implement this type of functionality? It would need to be something where I can compare cells within a column and set whether they are merged or not.

Or maybe a method I could override?

I've attached a mockup in Excel of the type of merging that I'm looking to accomplish in RadGridView.

Hi,

I am working on RadTreeListView which comes with default sorting on Control Column. I have a requirement to disable the default on RadTreeListView and enable the custom sorting on RadTreeListView. I had used the CollectionViewSource and also subscribed to OnSorting event handle and able to sort the binded item source. But view is not getting refreshed.

Using Comparer to sort the items in the itemsource and MVVM pattern.

Even thought binded item source is sorted as expected, the UI is not getting refreshed with expected sorted view. The control is getting sorted using the default control sorting mechanism.

Thanks,

Hi
   I have a small program that i've written to test a web site.  The program automatically logs into the website, changes the date, selects radiobuttons and refreshes the screen.  The problem is that I've encountered an autocomplete  RadComboBox  that I can identify, set focus and change the value.  However, it cannot get the event to fire once the "value" has been changed.
I have tried to fire an event with invokemember / setattribute - onchange, mouseup, mousedown, ontextchange, click, onclick, select item, submit etc to to no avail.

How do I get this RadComboBox to recognize a change programatically?

<code>

vb.net 2010
.....

For Each element As HtmlElement In m_document.GetElementsByTagName("input") 'input

If element.Name = RadComboBox Then

     Debug.Print("RadComboBoxt found")

     element.Focus()

      element.InvokeMember("click")

      element.SetAttribute("value", "00138SUPP")

    .........

</code>

Thanks!!!!!

Hello,

I am using RadDateTimePicker (Version 2016.1.328.45) in my WPF application. The requirement is such that I need to select all text inside the DateTimePicker when the user clicks inside it. For this purpose, I am using the GotFocus event, inside which I am getting the TextBox inside the DateTimePicker by the method FindChildByType<TextBox>() and then calling SelectAll() on this TextBox.

This doesn't work. Any suggestions or workarounds on how to achieve this?

Thanks.

I have a simple RadCartesianChart set up with binding. What I'm seeing is what appears to be yaxis labels, but these labels aren't related to the data itself. I have no idea where these extraneous numbers are coming from.

This is the xaml:

                    <telerik:RadCartesianChart x:Name="WeibullChart3" HorizontalAlignment="Left" VerticalAlignment="Top">
                        <telerik:RadCartesianChart.HorizontalAxis>
                            <telerik:DateTimeContinuousAxis LabelFitMode="Rotate" LabelFormat="yyyy/MM/dd" LabelInterval="2"/>
                        </telerik:RadCartesianChart.HorizontalAxis>
                        <telerik:RadCartesianChart.VerticalAxis>
                            <telerik:LinearAxis ToolTip="Duane Curve" LabelFitMode="Rotate" VerticalContentAlignment="Top" HorizontalContentAlignment="Left" />
                        </telerik:RadCartesianChart.VerticalAxis>
                        <!--<telerik:RadCartesianChart.Grid>
                            <telerik:CartesianChartGrid StripLinesVisibility="None" MajorLinesVisibility="XY" BorderThickness="1,0,1,1">
                                <telerik:CartesianChartGrid.YStripeBrushes>
                                    <SolidColorBrush Color="Black" />
                                    <SolidColorBrush Color="Black" />
                                </telerik:CartesianChartGrid.YStripeBrushes>
                                <telerik:CartesianChartGrid.XStripeBrushes>
                                    <SolidColorBrush Color="Black" />
                                    <SolidColorBrush Color="Black" />
                                </telerik:CartesianChartGrid.XStripeBrushes>
                            </telerik:CartesianChartGrid>
                        </telerik:RadCartesianChart.Grid>-->
                        <telerik:RadCartesianChart.Grid>
                            <telerik:CartesianChartGrid MajorLinesVisibility="XY"/>
                        </telerik:RadCartesianChart.Grid>
                        <telerik:LineSeries x:Name="Duane1" CategoryBinding="XVal" ValueBinding="YVal" ItemsSource="{Binding Document.WeibullDuanePlot}">
                        <telerik:LineSeries.PointTemplate>
                                <DataTemplate>
                                    <Ellipse Width="2" Height="2" Fill="Black" Opacity="0" />
                                </DataTemplate>
                        </telerik:LineSeries.PointTemplate>
                        </telerik:LineSeries>
                        <telerik:LineSeries x:Name="Duane2" CategoryBinding="XVal" ValueBinding="YVal" ItemsSource="{Binding Document.WeibullAggregatePlot}">
                           <telerik:LineSeries.PointTemplate>
                                <DataTemplate>
                                    <Ellipse Width="2" Height="2" Fill="Black" Opacity="0" />
                                </DataTemplate>
                           </telerik:LineSeries.PointTemplate>
                        </telerik:LineSeries>
                        <telerik:RadCartesianChart.Behaviors>
                            <telerik:ChartPanAndZoomBehavior ZoomMode="Both" PanMode="Both"/>
                            <chartView:ChartTooltipBehavior />
                        </telerik:RadCartesianChart.Behaviors>
                    </telerik:RadCartesianChart>
                    <telerik:RadLegend Items="{Binding LegendItems, ElementName=WeibullChart3}" Height="30">
                        <telerik:RadLegend.ItemsPanel>
                            <ItemsPanelTemplate>
                                <telerik:RadWrapPanel Orientation="Horizontal" ItemWidth="120" HorizontalAlignment="Center"/>
                            </ItemsPanelTemplate>
                        </telerik:RadLegend.ItemsPanel>
                    </telerik:RadLegend>
                </StackPanel>
            </telerik:RadTabItem>

This is the C# code:

            (WeibullChart3.HorizontalAxis as DateTimeContinuousAxis).Maximum = maxX;
            (WeibullChart3.HorizontalAxis as DateTimeContinuousAxis).Minimum = minX;
            (WeibullChart3.HorizontalAxis as DateTimeContinuousAxis).Title = "Date";

            (WeibullChart3.VerticalAxis as LinearAxis).Maximum = maxY;
            (WeibullChart3.VerticalAxis as LinearAxis).Minimum = minY;
            //(WeibullChart3.VerticalAxis as LinearAxis).Title = type.ToString();

            Plot_Title3.Text = type.ToString() + " Duane curve";

I have simple xml bound to RadListBox using XmlDataProvider. Xml is simple and it looks like this:

Provider is set like this:

And RadListBox looks like this:

While DisplayMemberPath works as intended and list box display captions, when I select item selected value is always null. Am I missing something or this is the bug in RadListBox control?
