Indenting Child Items from Parent in Self Referencing Grid

Hi,

I have used the below code to make the parent and child gird (self reference) column with as same.

this.binder = new ColumnWidthBinder(this.RadGridView1);

if (

dataControl.ParentOfType<RadGridView>() != null)
{
for(int i = 0; i < dataControl.Columns.Count; i++)
{
this.binder.RegisterColumn(dataControl.Columns[i], i);
}
}

all the column widths of parent and child coming correctly. the self reference hierarchy is also find but its like all left aligned. If I want to maintain the width as same and also the child items should indent from the parent (tree view hierarchy), what I have to do?

Any help appreciated?

Thanks,
Ramasamy

When cell is in edit mode, auto move focus to next cell using arrow keys

Hi Telerik team,

I have a requirement in which focus should move to next cell using arrow keys.

When cell is in edit mode, use arrow key to move right. After reaching to the extreme right, focus should move to next cell on further pressing right arrow key.

Please let me know the work around. If possible, a sample would be helpful.

Thanks
Bala

not properly saving the word formats using _telerikReportViewerModel.SelectedRenderingExtension prperty

hi Team,

we are using telerik reporting for generating reports and saving the reports in different formats such as ms-word, excel, cvs etc.,
one scenario is failing for us when user saves a file name as filename.x (x be any character). for example when he select a report and exports it as word and in the save dialog box if he gives the name as 'report.1' it is not saving as word format and user unable to open this. please let me know how to handle this. following is the code snippet :

private void CbSelectionChanged(object sender, SelectionChangedEventArgs e)

{

if (e.AddedItems.Count == 1)

{

var selection = e.Audited[0] as ExtensionInfo;

if (selection != null )

_telerikReportViewerModel.SelectedRenderingExtension = selection;

//clear selection

((ComboBox) sender).SelectedItem = null;

}

Exception Encountered in Samples

Hey Guys,

I seem to be having a lot of trouble getting the Persistence Framework to work at all. No matter whether I try to use IsolatedStorage or a stream, I get the following exception when I try to load the persisted data:

"Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"

Has anyone see this before, or know what I might possible be missing?

Thanks,
Mark

Updates to ObservableCollection not handled

We are databinding the ItemsSource property of the RadPivotMap to a property in our viewmodel of type ObservableCollection<>
If we set this property to a new value, the propertychanged event is triggered and the pivotmap is updated.
However adding/deleting items to/from the ObservableCollection does not trigger an update of the pivotmap.

This seems like a bug in the pivotmap-control as everything works correctly if we bind another control to the same collection.

Pre-defined Set of XCategory Labels in DataBound Line Chart

My data is structured such that I have 10 categories that I always want to display on the X axis, regardless of whether there are actually points in the bound collection for each of those 10 categories. Is it possible to define a collection of categories that I want displayed on the X axis prior to binding to an actual data source? Then, once the data source is bound, a line can be drawn between the YValues of the points in the categories that are actually present in the chart?

As a simplified example, say I have categories A, B, C, D, and E. My data has values B=10, D=15, E=12. I want to display a chart where all 5 categories are listed along the X axis with a line drawn between the B->D->E values. Is this even possible in a data bound scenario?

RadDocking inside RadTabControl

Hi,



With Q2 2011, it is not possible to drag RadDocking panes, when the raddocking is placed inside 

a radtabcontrol. See code below. I think that this is a known issue.

When do you expect to solve this issue?

In the meanwhile, is there a workaround?



Thanks,

Thomas

Possible bug in Radchart legend?

Hi all,

I have found a strange behaviour in the radchart legend and I'd like to know whether it is due to something I am missing or to a bug.

The scenario is pretty simple. I have a Radchart plotting several line series. Each series's parametrization (color, axis ranges, and so on) is stored in a settings class. As the user edits the series settings, the settings class is updated and changes are propagated to the chart (not via binding but using normal procedural code). The problem comes when the user changes the series color. I then use the following piece of code to change the color in the chart series:

obSerie.TelerikSeriesMapping.SeriesDefinition.Appearance.Stroke = new SolidColorBrush(obSerie.SerieColor);

This works great and the chart series changes its color accordingly. However, the small square in the legend associated to that serie does not update itself and keeps the color previous to the change.

Am I supposed to make any other updates in the control or is this a bug?
