Hi,

I am having trouble binding a class with 2 members to a RadGridView. The first member contains a dictionary to set the column header text and the second to fill the grid.

here is my sample project

cs

public Content()

{

// Get the labels from database

ContextSource.Labels = DictionaryFromDatabase();

// Get grid data from database

ContextSource.DataSrc = DataTableFromDatabase();

Listing.DataContext = ContextSource;

}

public class ContextSource

{

public DataTable DataSrc { get; set; }

public Dictionary<string, string> Labels { get; set; }

public ContextSource()

{

DataSrc = new DataTable();

Labels = new Dictionary<string, string>;

}

xaml

<telerik:RadGridView Margin="0"

AreRowDetailsFrozen="True"

AutoGenerateColumns="False"

CanUserFreezeColumns="False"

IsReadOnly="True"

ItemsSource="{Binding}"

SelectionMode="Single"

ShowInsertRow="False"

x:Name="Listing">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="{Binding Labels.[str_label0]}" DataMemberBinding="{Binding Path=DataSrc.[columnname0]}"/>

<telerik:GridViewDataColumn Header="{Binding Labels.[str_label1]}" DataMemberBinding="{Binding Path=DataSrc.[columnname1]}"/>

<telerik:GridViewDataColumn Header="{Binding Labels.[str_label2]}" DataMemberBinding="{Binding Path=DataSrc.[columnname2]}"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

When I set Listing.DataContext = ContextSource, it will only fill the header text property. The grid is not populated.

If I direct the Listing.DataContent directly to ContextSource.DataSrc then the grid is populated, but the headers are not set.

Listing.DataContext = ContextSource.DataSrc;

Any idea what I am doing wrong?

Kind regards,
Dennis

Multilevel list doesn't work correctly

Hi,

I use the last (Q3 2012) version of WPF controls. And I noticed that it can't get multilevel list (1.-1.1-1.1.1. for example) as it would be expected. The indent buttons behavior also doesn't work properly.

I would appreciate your advice or comments.

TabStripPlacement along side vertical align

Hi There,

I'm finding myself a bit stumped as to how to set the position of the tabs on the tab control if the placement is set to go along the left or right as per the attached image.

what it does right now is place the tabs from the bottom going up, but i would prefer to have them go from the top down...

is there a way to set this??

Thanks,
Nemanja

MergeField, CustomField update problem.

Hi,

The scenerio we are working on:

User A opens a template (docx) with RadRichTextBox.
Template has two MergeFields, "Subject" and "Signed".
User A updates the document and "Subject" MergeField is set to "User A's Subject".
Then User A saves the document as Docx and sends it to User B.
User B signs the document and "Signed" MergeField should be set to "Yes", but "Subject" MergeField shouldn't be updated.

The problem is, when User B opens the document, application does not have the User A's MergeFieldSource. So when application merge fields, it updates both "Subject" and "Signed" MergeFields.

I've tried couple of solutions, one with RadRichTextBox.MergeFieldToStringConverting event and one with inheriting MergeField.

In RadRichTextBox.MergeFieldToStringConverting solution, MergeFieldToStringConvertingEventArgs doesn't have the old/original value (before merging). If it was, I could pass the old value to the "Subject" MergeField when User B updates the document.

In CustomField implementation, I could have find a solution, if there were a functionality like; when protected override DocumentFragment GetResultFragment() method returns null, corresponding MergeField does not updates it's own value. But there is no such a functionality.

One another solution could be, enumerating the MergeFields in the document and update only the required ones. (This is possible in Office Word API). But I couldn't find a way to achieve the is with RadRichTextBox.

I've added a sample solution demonstrating the scenerio. (Using Telerik version 2012.3.1017.45)

Regards.

MaskedInput Password + Binding

Hi,

Is here someone who developed a MaskedInput Type= "Password" + Binding?

Thanks

OLAP Data Mistake - measures in wrong columns randomly

Hi all,
I've tried PivotGrid control on OLAP to a my local cube on Analysis Service and I noticed that data was in wrong columns (randomly).
So I've tried the WPF demo on OLAP and same problem on data.
In attach you can find mistakes to reproduce it on the example.
I think that this is a bug (I know that this control is still beta...) and I've also noticed this mistake in silverlight control too.

Regards,
Davide

WYSIWYG printing multiple pages

I have 2 scenarios where I want to WYSIWYG print a usercontrol. In one scenario I have a RadGridView that can span multiple pages in both X and Y directions. In the second scenario I have a RadTreeView that can span multiple pages in Y. I want to print the content of the grid and the treeview, without scrollbars. If possible I would like to provide the user with print preview functionality, and I want to include page numbers.
Does anyone know how to do this?
