Hi 

I am trying to create an Off-line Image Map creator using Radmap, Empty provider (Bing maps would be great but not posible) and kml sources intended for Telerik Reports. 
Using RenderTargetBitmap I tried to generate an image of the control, even if it's just showed for an instant, the problem is that tiles or shapes don't load and get a gray empty image (Only showing scale bar and map controls).
Is there any way to get the tiles or shapes loaded before that?

Any idea is appreciated.

When I set the MaxHeight property of a GridViewRow to 22, for example, and one of the cells contains longer text with multiple line breaks the text in other cells is no longer visible.

When I remove the MaxHeight property of the GridViewRow the row height is automatically adjusted to fit the height of the cell containing the longer thext with multiple breaks and the text in other cells reapperas but it is vertically centered.

I tried applying a cell style to other cells with VerticalContentAlignment set to Top but the text in other cells still remained hidden.

Also, even though I've set the TextWrapping to NoWrap and TextTrimming to WordEllipsis for the column containing the longer text with line breaks the text in that cell is displayed in two rows.

Is there any way to prevent text in other cells from disappearing when the MaxHeight is set to lower than what one of the cells content height is? If not, I'd say that this is a bug...

UPDATE: Using the cell style with VerticalContentAlignment set to Top actually works but than you have to keep adjusting the padding... is there a better solution?

Here is the attached image of how ugly that looks:

Hello,
  I just added the DiagramNavigationPane to a window that had an existing diagram.  I have set the Diagram property via binding as you showed in the online documentation.  I have noticed when I expand the pane there is no value for my zoom size, the autofit button is disabled and all I see in the thumbnail is a small red dot.  Are there other properties tied to the diagram itself that would affect the navigationpane?

I am using VS 2012 and 4.5 framework to create WPF XBAP project, and WPF RadControls. Problem I have is Page/Window/UserControl doesn't show telerik WPF rad controls. It is not a problem with System.Windows.Controls.

I used 2012.3.1029.40 version for the screenshots. but it is same with Q3 release binaries too.

What I am doing wrong here? Or Is something wrong with my environment or VS 2012? Please help, it is wasting my time a lot. :(

Hi,

I am using version 2012.3

I have a grid view which is autogenerating columns from a datatable. The reason I am using the RadGridView is so that the user can filter and/or sort with a minimum of hassle.

As part of the program, the user can delete rows from the table at any time. They can also add them back at a later date.

I have the add/remove working fine, basically using table.Rows.Remove(row) this triggers the AutoGeneratingColumn event for each column as the table basically reloads.

Where I am having trouble is when the user sorts or filters the data before removing a column. If the grid is sorted and you remove a column, the output shows "A first chance exception of type 'System.ArgumentException' occurred in System.Data.dll" and the entire grid becomes blank. It does not come back if you try adding the row back.

If the user has added a filter to the grid and removes a row, it looks like it worked. The data showing is whatever you had filtered already, minus that row. The problem is that it says that there is no filter, so you cannot remove the previous filter.

How do I change the data that the grid is bound to and have the sorting/filtering update at the same time?

Thank you,

Eli

Hello,

I have been using the RadGridView for a project and I am having an issue with custom templating and styling.  I have set up custom styles for the RadGridView, GridViewRows, and a few other controls.

The problem I am having is that my GridViewRow style is not being applied to the "Click here to add new row" row, nor the editable row that appears when you click it.

To further compound everyone's confusion, when I create a basic custom style and apply it to the "NewRowStyle" property, it messes up the way the normal rows as well as the headers of the grid display.


Am I missing a step on applying custom templates and styles?

Thank you.



(For further information, I am using the latest Q3 trial release for WPF.  Development is in Visual Studio 2010).

Hi,

I know that the default WPF combobox has the same behavior - but maybe RadCombobox can do it better.
What I want is a ComboBox where the user can select a single item from the dropdown.
This works so far - but when hovering an item with the mouse the user gets lost because the Selected Item is no longer highlighted.

Although I could create such a combobox with a togglebutton and a listbox in a popup I would prefer to use RadComboBox.

Is there a way to achieve this (easily)?

Thanks
Manfred

Hello Telerik team,

I have set the following properties in the gridview excel copy related functionalities.

 

 

My requirement:

I have field in the grid that can be nullable. The CellEditTemple of the field has a dropdown.




Now when I try to paste a non-empty value onto the grid cell I can see that the PastingCellClipboardContent event gets fired.

But when I try to copy a empty cell from the excel and paste onto the grid cell the PastingCellClipboardContent even is not fired.

I wanted to set selected item of the dropdown in this case to null, but the PastingCellClipboardContent doesn;t seem to fire when the cell copied is empty.

I even tried to set the ClipboardPasteMode property to "OverwriteWithEmptyValues" but even this did not seem to help me.

If possible, could you please help me with my requirement.


Many thanks!

Mausami

Hi guys,

I would like to display my RadGridView row details outside of the RadGridView (working with RadControls for WPF Q3 2012
).
I found some samples implementing the DetailsPresenter + DetailsProvider pointing to the RadGridview's RowDetailsProvider.
I tryed to implement it working with my RadGridView's RowDetailsTemplateSelector but the rowdetail still display inside the Grid, below the selected row. 

I tried another solution, setting the DetailsPresenter's "ContentTemplateSelector" instead of the RadGridView's RowDetailsTemplateSelector. In that particular case, the External DetailsPresenter does not bind to Selected Row Data: nothing is displayed in the details.

Any idea how I'm supposed to implement that?
Thanx' for your help.
