[Solved] Load image in cell when loading any database

Hi,

I have an app that loads any database and presents the data for the tables in a GridView. I do not define columns in the XAML since I load any database. I'd like to be able to determine when a column from the database contains images and display the images in the grid. Can you tell me how to do this? I see examples in the forms and KB but they all seem to create the columns in XAML since they know the database schema ahead of time.

Thanks,

Gord

Commit button binding

Hello! I'm working with the DataForm and I have what I would guess is a simple question. I'm using a DataForm to edit a single item and I'd like to bind the Commit button to an ICommand on my ViewModel. How do I go about doing that?

Selecting first tab

Is there any easy way to ensure at least one Tab is selected? My tabs are dynamic, and hide and show themselves based on stuff. I want the first tab to be selected, if no tabs are selected... preferably without lots of work =/

ListBox drag-drop behavior

I just posted a new solution for implementing drag-drop between ListBox and other controls, and in case you are using WPF - other applications. You can find more information and a sample application here:

Selected Timeslot

How do i find the selected timeslot or the clicked timeslot in the new radscheduleview control. I saw that i would be able to invoke the dialog and cancel it from showing and I get Occurence details there. However, there doesn't seem to be a straightforward way to get the selected timeslot. Could you please guide me in how I could get the selected slot.

Thanks

[Solved] How to style the group items.

Hi,

I need to style a few bits from the grid that only appear when the grid is grouped by a column. I am attaching an image with the parts that I need to change:

1. The square of Header that appears at the top (I need to change the colour to match the rest of the grid's header)
2. The background of the blank rows and columns that appear when the grid is grouped.
3. The grey squares beneath the expander (also need to change the background).

I tried following your instructions detailed here:

http://www.telerik.com/help/wpf/radgridview-styles-and-templates-styling-the-group-panel.html

But in Blend 4 I cannot generate the template (Edit Copy is disabled). I am also attaching a picture of this problem. Do I need to do something to enable this for the grid? It works fine with RadComboBox, for example.

How should I proceed?

P.S. I notice now I cannot add attachments to this post. Here are two links to the images:

Speed Chart with ControlTemplate

I have a chart with one basic line series with 3500 points. I am using data binding and set the ItemsSource to my list of objects. I have turned off the labels, pointmarks and tooltips but It still takes up to 15 seconds to render. I have read that I can remove some things using a control template and that this would speed it up. I dont know how to do this. Does anyone have an example?
Thanks
