Observable Collection IndexOf() VS2012 Bug?

Hi,

Firstly I must point out that this is to do with vs2010 and 2012 rather than a telerik product.

I have the following code:

private void treeMenuItemEditProduct_Click(object sender, RadRoutedEventArgs e)

{

if (this.treeProducts.SelectedItem != null)

{

RadTreeViewItem treeViewItem = (RadTreeViewItem)treeProducts.SelectedItem;

Products selectedProduct = treeViewItem.Tag as Products;

EditProductsWindow editProductWindow = new EditProductsWindow(selectedProduct);

editProductWindow.Owner = Window.GetWindow(this);

editProductWindow.IsRestricted = true;

editProductWindow.WindowStartupLocation = WindowStartupLocation.CenterOwner;

editProductWindow.ShowDialog();

//Check if the closing window achieved or failed its task

if (editProductWindow.DialogResult == true)

{

//Get collection Index of selected product

int index = TAS2Database.DBTimers.GetProducts.EnabledProducts.IndexOf(selectedProduct);

//Remove Selected Product from List

TAS2Database.DBTimers.GetProducts.EnabledProducts.Remove(selectedProduct);

//Add new Product to Products List

TAS2Database.DBTimers.GetProducts.EnabledProducts.Insert(index, editProductWindow.newProduct);

//Amend TreeViewItem

treeViewItem.Tag = editProductWindow.newProduct;

treeViewItem.Header = editProductWindow.newProduct.Name.ToString();

treeViewItem.ToolTip = editProductWindow.newProduct.ID.ToString();

}

else

{

RadWindow.Alert("Please select a product to edit.");

}

When I execute the following line of code for a second time in VS2012 I get a return value of -1, where as in VS2010 in works fine every time.

//Get collection Index of selected product

int index = TAS2Database.DBTimers.GetProducts.EnabledProducts.IndexOf(selectedProduct);

When I say a second time, I mean that I execute the "click" function once and all works well, but when the click executes a second time, then I keep on getting a return value of -1. As I previously mentioned, this problem does not exist when using VS2010.

Does anyone have any ideas of why this may be?

Thank you very much for your time taken to read this and I look forward to any responses that you may have.

Rob

Embedding RadGridView in 2nd column

Hi there,

can arbitrary controls, in my case RadGridView Controls, be embbeded in a cell?

I need a control, where the first column represents a hierarchie and the second colum contains a list of items for each hierarchie-level.

The nested / grouped RadGridView looks similiar, however I need the group to be in another column. Like this:

hierarchy | items

==============================

root |

------------------------------

> child | -------------

| |item 1 | 1 |

| |item 2 | 2 |

| -------------

------------------------------

Thanks for any hints!

Cheers,

Jan

[Solved] RadDatePicker throws Exception

Hi.

I've been using Telerik controls for a while, and with the latest release, RadDatePicker throws a NullReferenceException after opening the dropdown of the control, configured with DateSelectionMode= "Month".

This happens on Telerik RadControls for WPF 2013.1.220.40

Could you fix this problem?

XAML Code:

<telerik:RadDatePicker Name="MonthRDP" Grid.Column="1" DateSelectionMode="Month" />

StackTrace:

[Solved] Culture problem after upgrade to 2012 Q3

I'm setting current culture during application startup:

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB");

Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-GB");

Then on Grid I have following column

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=StartDate}" Header="Start Date" DataFormatString="d" IsSortable="True" />

On version 2012 Q2, Grid displayed this column in en-GB format, but after update it uses en-US. All other controls (like date picker) are displaying date correctly. Only grid has problem.

[Solved] Localization problem with columns of type double (decimal separator)

Hi,

When I have a GridViewDataColumn of type "double", it is displayed with a "." as decimal separator, disregarding the localization settings (where in my case "," is the decimal separator). On the other hand, the filtering of the colum does look at the localization.
So the users sees for instance 1.51 in the column, but has to type 1,5 in the filter textbox, or otherwise a error is generated (which is very confusing to the user). Or maybe I am missing something here ?

Kind regards,

Martin

Telerik Reporting and Docking

I am not sure if this is reporting issue or docking issue. (I did not see a forum for WPF Reporting)

I have an issue using the Telerik reporting Q3 2012 (SP1) Specifically the Telerik.ReportViewer.Wpf.dll (version 6.2.13.123)

I create a WPF application
On the MainWindow.xaml, I add RadDocking as follows:
<Grid>
   <telerik:RadDocking>
     <telerik:RadSplitContaier>
       <telerik:RadPaneGroup>
      <telerik:RadPane>
           <tr:ReportViewer />
        </telerik:RadPane>
       </telerik:RadPaneGroup>
     </telerik:RadSplitContaier>
   </telerik:RadDocking>
</Grid>

When I run this, the main window opens fine. Now drag the window and dock it somewhere in the main window.
The result is an exception (NullReferenceException) the stack trace mentions the ReportViewerModel.SetReportSourceEffective (ReportViewerModel.cs line 983)

Note: This seems to be an issue with the SP 1 dll because this example code runs fine when using the Telerik reporting Q3 2012 dlls (i.e Telerik.ReportViewer.Wpf.dll version 6.2.12.1017)

Help?

Styiling of pie chart

Hi,

We have a situation where we need to style the RadPieChart so that it appears as shown in the attached mockup. As you can see, the selected slice of the Pie Chart has a 3D-like appearance whereas the remaining slices appear in 2D, and this is where we got stuck and didn’t know how to style something like that. Is there any way to modify the control template of the “selected slice”? But then, how do we display other selected slices to have such an edge when they are selected?

Screenshot of the pie chart is attached please check

thanks in advance,
Srinivas.

For example: If i search for a City: New York by entering "New York" in a RichTextbox and then do another search for "Los Angeles" and then while doing a search for the third time, I should get the previous 2 options as well.

Please let me know

Thanks

Basic PaletteManager Solution

Is there a basic PaletteManager solution available that demonstrates the changing styles process like in the Executive Dashboard project?

I've spent days trying to recreated it from the downloaded sample solution. But honestly there is too much going in the files to figure it out.

Any help would be appreciated.

Simple table filters (FROM and TO)

Hi everyone,

I would like to ask you what is the simplest way to have column filters only for number and datetime values where I would set only FROM and TO value to filter rows?

I hope you understand what I mean.

Thank you for your replies.
