Is it possible to 'preview edit' or enable one-click editing?

I'm currently evaluating the GridView control for a project and am trying to determine if it supports a feature I would like to have. I've searched for this and found nothing, but I'm not sure if there's a common name for the feature I'm unaware of.

What I would like is the ability to show the editor template for a cell on a certain trigger, but without the row/cell entering edit mode; it'd be a sort of 'preview edit' mode. Then, when the control gains focus it would enter 'true' edit mode.

This might make more sense in context. Say I have a column displaying dates, and the editor I want to use is a standard .NET DatePicker. To edit this value I would like it to work like this: when I mouse-over a cell in that column, the editor template appears for that cell. Then, I can click into the editor textbox or click on the button that launches the popup; either of these would enter edit mode. This would allow me to edit the value with one fewer click than I'm currently able to.

Is this supported and I'm missing it, or is it possible to write myself, or just completely unsupported? Thanks.

How to dynamically databind the Header of a RadPane?

Hi telerik,

I'd like to write code that dynamically binds the Header to different properties on the DataContext depending on a bool.
I've found below code, but 'Header' is not the object to use in code - can you help me?

Thanks,

Anders, Denmark

 
 
 
Binding myBinding = _isPropertyEditor ? new Binding("DisplayNameEditor") : new Binding("DisplayNamePropertyEditor"); 
 
myBinding.Source = DataContext;
Header.
 
SetBinding(TextBlock.TextProperty, myBinding);

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
