When I save a file, and attempt to save it again later after making changes it keeps asking for the file name even though I've already defined it (like it thinks I'm using Save As, rather than Save). How can I solve this issue??

Hi,

I try to add an InlineUIElement for TextBlock to RadRichTextBox. The code is,
// Set font type and size in TextBlock
string fontName = "Verdana";
int fontSize = 12;
System.Windows.Media.FontFamily fontFamily = new System.Windows.Media.FontFamily(fontName);
TextBlock tagBlock = new TextBlock
{
    Background = new SolidColorBrush(Colors.LightGoldenrodYellow),
    FontFamily = fontFamily,
    FontSize = fontSize,
    Text = tagConent
};
 
// Get the size of TextBlock
tagBlock.Measure(new System.Windows.Size(Double.PositiveInfinity, Double.PositiveInfinity));
System.Windows.Size size = new System.Windows.Size(tagBlock.DesiredSize.Width, tagBlock.DesiredSize.Height);
 
// Create an InlineUIContainer containing the TextBlock
Telerik.Windows.Documents.Model.InlineUIContainer tagContainer = new Telerik.Windows.Documents.Model.InlineUIContainer(tagBlock, size);
 
// Insert the InlineUIContainer into the caret position
radRichTextBox1.InsertInline(tagContainer);

It works basically fine except text in TextBlock align top compared to text outside block (See attached picture). This is very similar to one in http://stackoverflow.com/questions/5225268/wpf-how-to-align-text-in-inlineuicontainer-content-with-outer-text-in-richtextb. But I can not find inlineuicontainer.BaselineAlignment as suggested in the post for Telerik.Windows.Documents.Model.InlineUIContainer. I need help on this.

Thanks,

Hi,

I created RadMenu dynamically using HierarchicalDataTemplate using following code.

       <HierarchicalDataTemplate x:Key="MenuItemTemplate"
                                 ItemsSource="{Binding SubItems}">
            <TextBlock Text="{Binding Text}" />
        </HierarchicalDataTemplate>

        <telerik:RadMenu x:Name="radMenu" Height="22"
                          VerticalAlignment="Top"
                          Orientation="Horizontal"
                          ItemTemplate="{StaticResource MenuItemTemplate}" ItemClick="OnRadMenuItemClick" />
but in code behind of the OnRadMenuItemClick Event i am unable to find out name of the menu item that clicked.

		private void OnRadMenuItemClick(object sender, RadRoutedEventArgs e)
		{
			RadMenuItem item = e.OriginalSource as RadMenuItem;
 
			if (item != null)
			{
				switch (item.Name)
				{
		
				}
			}
		}

when i click on menu item .. item.Name allways comming as null.
can one please help me how to get the name of the menu item that clicked

but it is working for statically developed radmenu

Thanks

I am building a WPF app where I work and I want to use the RadPanorama for the Start Screen or "Launching Pad" for the App.  I understand, and have seen the numerous threads, that there is no RadPanorama for WPF. 

However, is there any reason I cannot embed one in a WindowsFormsHost? 

Seems to work after a VERY quick little test but I am wondering if anyone has any feedback on doing it this way?  Somethings are very 'messy' to get at with out the Design Time support.  Is there a way around that? 

Additionally, doesn't seem to be a ton of documentation for manipulating a RadPanorama in Code Only, am I missing it?

P.S. I appologize if this is not the correct Forum.  With the whole WPF, RadPanoram, WindowsFormHost gammit I wasn't sure.

Hello!
I'm writing an application with a radgridview bounded to a Linq EntityFramework query object and I have a problem in modifying cells content programmatically.

Once my grid is shown with bounded values I want to modify these values direclty in the gridview in editing mode, and this task works fine. Now I want to add a row to the grid with values taken from a function in the code behind. I have a series of value and I want to add them in a new row and show it in my gridview. Since I don't want to put them in database I can't save changes to my entity frameworks query object and then rebind to the gridview, but I simply want to add a row to the grid with my values, until the user want to definitely apply changes.

I tried making a dataset from my linq to entity query (same records as written in the gridview), and then Added new row to the dataset and binding it to the gridview. The last problem is to save changes in database, I should take values from the gridview back to a linq entity query and save changes. After creating a dataset from linq object I should now create a list (linq) from dataset...

To do this I set a new linq to entity query taking records from my dataset, but at this point my application rises error and I can not retrive data to save.

Does anybody faced a similar problem and can give me an example on how to procede? Any example? I search everywhere without finding a solution. In my application I don't use MVVM...

If necessary I can post my faulty code
