Hello,
I'm working on an app for my internship and I have to make a save / load the content when we open and close the application and we click on the button "save" and "load".
I watch many times your example and I do a lot of research on google and the forum but I don't know and I have no idea how to do the GetPageContent() method.

I know this method is specific but I would like you to send me an example in C # so I can get an idea of method to follow to implement this method.

Thank you very much in advance

Hello,

I was wondering, is it possible to add a new document to the document host but don't immediately make that new document active/visible? To clarify, the behavior I'm looking for is like in Chrome, when you middle-click a link, it opens the link in a new tab, but doesn't switch to it, it just opens it in the background.

What I'm trying to do is allow users to quickly open multiple tabs. This is tough to do when you have to keep switching back to the original tab that triggers the new tabs.

Thanks,

Joel

Normally the pivot element has a parent and child (on expanding) and the parent is usually some kind of aggregation of all its children. I have a requirement where-in the parent should not  be an aggregation and its independent of children. Say parent has some 5000 value, upon expanding the value need not be a sum, it can be more than 5000.

 

Is this possible with Pivots or do I have to use any other controls?

My Challenge:

I am trying to capture the selected row in a RadGridView which I would like to store in the database when the user exits the screen. When the user re-enters the screen I would like to programmatically select the row previously stored.

I set up a proof of concept using 2 Test buttons and a GridView:

Test 1 Button:
 - Get the selected row
 - Cast the selected row object to a string (which would be stored in the database)
 - Cast the string back to an object (simulate return from the database)
 - Add object to a list of objects
 - Clear selected items in the grid

Test 2 Button:
 - Execute the Select method on the GridView with the list of selected objects as an argument
 - Check the GridView SelectedItems count

Problem:
The select method executes but nothing happens. What am I missing? 

Sample Code:

private object rowObject = new object();
private List<object> rowList = new List<object>(); 

private void test1_Click(object sender, System.Windows.RoutedEventArgs e)
{
  if (ProjectListingGridView.SelectedItems.Count > 0)
  {
      var item = ProjectListingGridView.SelectedItem.ToString();

      if (item != null)
      {
        var rowObject = (object)item;
        rowList.Clear();
        rowList.Add(rowObject);
        }

      this.ProjectListingGridView.SelectedItems.Clear();
  }
}

private void test2_Click(object sender, System.Windows.RoutedEventArgs e)
{
  var selectList = rowList;

  try
  {
       ProjectListingGridView.Select(selectList);
  }
  catch (Exception)
  {
      throw;
  }
    var cnt = ProjectListingGridView.SelectedItems.Count;
}

The demo(GridView.WPF.Commands)  is what we want. But when I write code , I find the command is bind to "telerikGrid:RadGridViewCommands.BeginInsert" , which is compiled into Telerik.Windows.Controls.dll. It is not a custom command in viewmodel. So how can I add my custom logic (such as save to database) to these command?

your demo :
<StackPanel Orientation="Horizontal"
                    HorizontalAlignment="Center"
                    Margin="0,5,0,0">
            <telerik:RadButton Width="150"
                               Content="Delete selected rows"
                               Margin="0,0,5,0"
                               Command="telerikGrid:RadGridViewCommands.Delete"
                               CommandTarget="{Binding ElementName=RadGridView1}" />
            <telerik:RadButton Width="150"
                               Content="Add new row"
                               Margin="0,0,5,0"
                               Command="telerikGrid:RadGridViewCommands.BeginInsert"
                               CommandTarget="{Binding ElementName=RadGridView1}" />
            <telerik:RadButton Width="150"
                               Content="Save insert/edit"
                               Margin="0,0,5,0"
                               Command="telerikGrid:RadGridViewCommands.CommitEdit"
                               CommandTarget="{Binding ElementName=RadGridView1}" />
            <telerik:RadButton Width="150"
                               Content="Cancel insert/edit"
                               Command="telerikGrid:RadGridViewCommands.CancelRowEdit"
                               CommandTarget="{Binding ElementName=RadGridView1}" />
        </StackPanel>

Hello,

I'm missing a way to display a label for a GridLineAnnotation in a polar chart. What is the intended way to achieve this?
I would have created my own annotation type, but the necessary methods are all internal, so overriding is not possible.
Is there a reason why these are not declared as protected internal? (This would be helpful anyway, as I also also need
other annotation types which are not possible at the moment...)

Is there a way to set minimum/maximum width of RadPane. When I try to do that, that the RadPanes don't fill the complete space (see attached image). Also when I resize the window I want to be able to set RadPane's widths.

Other solution I have seen is that set the Realtive size of the RadPanes in a RadPaneGroup. However I have some windows, I want them to be of FixWidth/FixHeight, and with Resizing, I don't want them to change.

If you have an example, that illustrates different resizing options do let me know.

Hi,

Is the All day area going to be implemented in the RadScheduleView? We really need this feature because it's available in the old RadScheduler which we are porting our code from.

Best regards,

I have RadChart that populated with real time data.

This is my RadChart configuration:

My chart is populated with real time data via timer, this is my timer tick event:

Please see my attach screenshot:

1. How can i remove value label ?

2. How can i remove the upper and the lower 2 stripes that i have on my chart ?

3. As you can see my chart series line is fill only half of my chart and this is how it is all the time and in additional after adding few points into my chart my application is stuck and become more slow, why this is happening and how can i fix it ?
