Hi,

is it possible to show/hide the GridLines via condition? So if condition is true, then show horizontal Gridline, if not, then hide it?
Want to make it, because Merging is not as possible as in older Application (take a look at attachment).

Or is there any other solution to show grid as attachment with WPF RadGridView?

Best regards,

David

MEF and PRISM module Button loading

I have managed to set up a PRISM region within the radRibbonView.RadRibbonTab which then has radRibbonGroup's loaded in from the modules containing the buttons for that module. All good so far, however the modules donot load in the order which the radribbongroups need to appear in the tab.

I have tried using the radOrderedwrappanel in conjunction with the groupvariant priority as per snippit below to provide a solution with no luck. Is there a way of doing this or will I have to look into custom loading order of the modules?

I ahve also added a custom regionAdaptor which seems to be working fine to allow the radribbongroups to be loaded into the orderedwrappanel. However the ordering and sizing didnt work - it started wrapping after 3 ribbonGroups and it didnt order the groups correctly.

<telerik:RadRibbonGroup Header=" Order Search ">

<telerik:RadRibbonGroup.Variants>

<telerik:GroupVariant Priority="2" Variant="Large"/>

</telerik:RadRibbonGroup.Variants>

<telerik:RadOrderedWrapPanel>

<telerik:RadRibbonButton LargeImage="/Icons/48/Search.png" Size="Large" telerik:ScreenTip.Title="Order Search"/>

</telerik:RadOrderedWrapPanel>

</telerik:RadRibbonGroup>

I would like to know if it's possible to add new words to the existing spellchecker of Telerik?
Also, I would like to know if it possible to use an external spellchecker such a medical spellchecker with Telerik components?

Thank's

Drag and drop reorder rows

Hi there

For the past day I'm trying to implement drag and drop behavior in the same gridview. I used the demo example to implement this.
The events are fired when I click a row and drag, but the row isn't dropped.
When I debug the code, the DragDropPayloadManager.GetDataFromObject() method returns null in OnRowDragOver and OnDrop for the following lines:

--- OnRowDragOver

var details = DragDropPayloadManager.GetDataFromObject(e.Data, "DropDetails") as DropIndicationDetails;

--- OnDrop

var draggedItem = DragDropPayloadManager.GetDataFromObject(e.Data, "DraggedItem");

var details = DragDropPayloadManager.GetDataFromObject(e.Data, "DropDetails") as DropIndicationDetails;

Because of that, both events return nothing.

Am I missing something?

Thanks in advance
Lowie

Slow switching between tabs

Hi,

I've a RadTabControl with some RadTabItem and one of them contains a RadGridView with a lot of content (I bind an ObservableCollection).
When I switch from any tab to this one it always takes some time (a few seconds) so it seems that in some how the gridview is loaded again.

Since this list is static, are there a way to improve the performance?

Change TabItem - Binding Problem

Hi,

i use a RadTabControl with a AutoCompleteBox on it. Here i select a customer and fill the TabItem with data.
After changing the Tab the TabItem is empty? the AutoCompelteBox is empty, too!

The Main Problem is that i create each tab by code and in each tab a usercontrol is loaded. Now i select a customer
and display the data in the tabitem. When i change the tab the first one is empty again when i come back.

What is to do to hold the information in the TabItem?

THanks
Best Regards
Rene

put some mergefield readonly

Hi,
I want to "protect" mergefield inside my document, to prevent user to change the display of the field directly in the richtextbox(i use a specific editor to edit the value of my mergefield).

I tried to write a procedure to put or remove readonly on my mergefield, but I have some trouble to make it work :

private void SetMergeFieldReadOnly(MergeField field, RadRichTextBox richTextBox, bool isReadonly)

{

var fieldEnd = richTextBox.Document.EnumerateChildrenOfType<FieldRangeEnd>()

.FirstOrDefault(fs => (fs.FieldRangeStart.Field is MergeField)

&& (((MergeField)fs.FieldRangeStart.Field).PropertyPath == field.PropertyPath));

if (fieldEnd != null)

{

var fieldStart = fieldEnd.FieldRangeStart;

var posFieldStart = new DocumentPosition(richTextBox.Document);

var posFieldEnd = new DocumentPosition(richTextBox.Document);

posFieldStart.MoveToInline(fieldStart);

posFieldEnd.MoveToInline(fieldEnd);

if (isReadonly) // add readonlyrange

{

richTextBox.Document.Selection.Clear();

richTextBox.Document.Selection.SetSelectionStart(posFieldStart);

richTextBox.Document.Selection.AddSelectionEnd(posFieldEnd);

richTextBox.InsertReadOnlyRange();

}

else // remove readonlyrange

{

// 1st method - doesn't work.

//richTextBox.Document.Selection.Clear();

//richTextBox.Document.Selection.SetSelectionStart(posDebField);

//richTextBox.Document.Selection.AddSelectionEnd(posFinField);

//richTextBox.DeleteReadOnlyRange(); // <-- no error but the field is still readonly after that.

// 2nd method - works but not properly

var readOnlyRangeStarts = richTextBox.Document.EnumerateChildrenOfType<ReadOnlyRangeStart>();

var posDebReadOnly = new DocumentPosition(richTextBox.Document);

var posFinReadOnly = new DocumentPosition(richTextBox.Document);

foreach (var readOnlyRangeStart in readOnlyRangeStarts)

{

if (readOnlyRangeStart.End != null)

{

posDebReadOnly.MoveToInline(readOnlyRangeStart);

posFinReadOnly.MoveToInline(readOnlyRangeStart.End);

if ((posFinReadOnly >= posFieldStart) && (posDebReadOnly <= posFieldEnd))

{

richTextBox.DeleteReadOnlyRange(readOnlyRangeStart); // remove the protection on ALL the readonly range !!!

}

I wonder if there are not some easier way to do this ? (Or I might be doing something wrong ?)

At the moment, I can only set/unset readonly ALL the mergefield of the document. It works, but sadly it's really slow ...

Are they're some way to "lock" the fields without using some ReadOnlyRange ?

Thanks.

Unable to use UI(after unpin) which hosted in another app domain with RadDock

Hello Telerik team,

I’m having trouble with hosting an Addin UI in RadDock.

I wrote a demo to reproduce this issue. download demo here
You can see if you unpin the RadPane, you will no longer be able to focus the textbox. I’m wondering if this is a known issue and is there any workaround for this?

I have read this (http://www.telerik.com/community/forums/wpf/docking/wpf-frame-control-not-visible-in-floating-window.aspx) and this (http://www.telerik.com/community/forums/wpf/docking/radpane-not-displaying-webbrowser-content-while-floating.aspx) threads to make the UI display in RadPane. But when RadPane is in unpinned state, the UI inside it is not able to be used. When I click it, the RadPane automatically hides.

Edit Cells in pivot grid

Hello,
i want to display a matrix that holds a weighted graph, so for example:
Point A Point B Point C
Point A 10 1 15
Point B 15 8 8
Point C 5 10 1

The pivot control looks very nice and it is also possible to create categories and collapse them,
but how can i edit the cells?
It would be enough to double click on a cell and edit it in another window ...
thanks!
