Hi,

I have a simple RadGridView with some setting but this grid is not editable. 

This gridview is filled thanks to a dataset product from a sql database.....

Through code behind I have the folloginw code:

        Dim currentDataRow As DataRow = Me.MyDataGrid.SelectedItem
        If currentDataRow IsNot Nothing Then
            currentDataRow.Item("STATUS") = status
        End If

This code works fine....so far, so good....but what is the right event in RadGridView to capture the time when the value of the cell is modified?

Thanks

Is there a way to programmically remove the focus on a radgridview or one of the rows.


I have tried using the Focusable property which functionally works but it leaves the row still highlighted.

I have a couple of grids in panels where the visibiliy is toggled. They have keyboard commands and when I go to a new panel its possible to active commands on the invisible grid.

Thanks in advance

Currently the "Members DropDown" is a list of available members, which can serve as a filter criteria.

In our application, we provide the users, hundreds of members that they can filter. So, it would be nice to categorize the dropdown and show members under the categories, or even better, use a different UI control instead of a dropdown.

How flexible is this feature supported in your API? 

Hi,
I have a PanelBar that is templated by a HierarchicalDataTemplate.  The PanelBar also includes a ContextMenu, and when I select "Rename" in the ContextMenu I would like the selected List Item to switch to an ItemEditTemplate.  However, the HierarchicalDataTemplate doesn't provide that option and putting an ItemEditTemplate in the PanelBar doesn't seem to do anything when I switch the item IsInEditMode = true.  What do I have to do to switch to my EditItemListTemplate?  Thank you for your help!!

Edit: I am developing in .Net 3.5 C#, using Telerik WPF 2011.03.1219.0.

I am building multi-axes line graphs using the RADCartesianChart control.
If I fill in the control using XAML, I get PanZoomBars as expected.  See sample XAML below

<telerik:CartesianChartGrid MajorLinesVisibility="XY"  />
</telerik:RadCartesianChart.Grid>


</telerik:RadCartesianChart>
</Grid>
</UserControl>
If I attempt the same thing in code, then the graphs appear correctly, but the PanZoomBars are missing! 
Code extract from a user control code behind file showing how I am filling in the control is shown below  (NOTE chart is a RadCartesianChart control specified in XAML of the UserControl).  

private void UpdateFromCollection()
{
if ((XAxes != null) && XAxes.Any() && (YAxes != null) && YAxes.Any())
{
var xAxis = XAxes.First();
this.Chart.HorizontalAxis = new LinearAxis
                            {Name = xAxis.Name, Title = string.Format("{0} ({1})", xAxis.Name, xAxis.Units)};


this.Chart.Behaviors.Clear();
var panAndZoomBehavior = new ChartPanAndZoomBehavior();
panAndZoomBehavior.ZoomMode = ChartPanZoomMode.Both;
panAndZoomBehavior.PanMode = ChartPanZoomMode.Both;
this.Chart.Behaviors.Add(panAndZoomBehavior);


var trackBallBehaviour = new ChartTrackBallBehavior();
trackBallBehaviour.ShowIntersectionPoints = true;
trackBallBehaviour.ShowTrackInfo = false;
this.Chart.Behaviors.Add(trackBallBehaviour);


this.Chart.Series.Clear();
bool firstYAxis = true;
foreach (var yAxis in YAxes)
{
var scatterLineSeries = new ScatterLineSeries {DisplayName = yAxis.Name};
scatterLineSeries.Stroke = new SolidColorBrush(yAxis.Colour);

for (var i = 0; i < xAxis.Data.Count; i++)
{
var sp = new ScatterDataPoint { XValue = xAxis.Data[i], YValue = yAxis.Data[i] };
scatterLineSeries.DataPoints.Add(sp);
}
if (firstYAxis)
{
this.Chart.VerticalAxis = new LinearAxis() { Name = yAxis.Name, Title = string.Format("{0} ({1})", yAxis.Name, yAxis.Units) };
firstYAxis = false;
}
else
{
scatterLineSeries.VerticalAxis = new LinearAxis() { Name = yAxis.Name, Title = string.Format("{0} ({1})", yAxis.Name, yAxis.Units) };
}
this.Chart.Series.Add(scatterLineSeries);
}
}
}


Is there something else I have to specify in order to get the PanZoomBars included?

Hi all,

I am using a custom min/max value for my x-axis (mainly to simulate the live data feel by scrolling the x-axis on every data update). However, it seems that when I run for the graph for a long period of time, the data points that should be out of the graph display range are being displayed on the edge of the graph instead of being omitted completely. Attached is a screenshot of the issue. 

I read somewhere else that this is a known issue. If so, are there any workarounds for omitting the data that won't fit in the current x-axis?

Furthermore, I also tried the workaround of having two separate data sets (one for storing all past values and another for holding the actual displayed data, which is a subset of the previous). However, when I change the ItemsSource from one to the other, the graph displays some strange behavior (erratic line drawings, etc.), which is why I am hoping to find a workaround without having to switch my data source.

Thanks,
Jin

Hi,
Is it possible to get the X and Y values of the point, where user right clicked on the Stacked Area to open the context Menu?
Or any nearby DataPoint  X,Y Values.

Please Reply as soon as possible.

Thanks in Advance.

Hello,

I am looking for some sample code for raddiagramcontrols loading asynchronously using a background worker. Please share if you have any

Hello,

I need to hide minimize and maximize buttons in my radwindow.
I used your example on http://www.telerik.com/community/forums/wpf/window/window-style-and-template.aspx and modified ControlTemplate to hide the buttons, its works fine.
But I use a Style Manager in my Application
            StyleManager.ApplicationTheme = new Expression_DarkTheme();

After adding the ControlTemplate I can't style Radwindow header anymore.
Can you please help me ?

i need 2 clarification

1.
