I have auto generated columns on (I want that so the code can be generic, I don't want to specify table names and layout).
I am binding to 3 tables in a DataSet by an Id (PROPERTY_ID) , so there are three levels of nesting.

 

 

 

 

 

 

 

 

 

 

 

// start code snippet...

x_GRID.AutoGenerateColumns = true ; 

  

dd.Tables.Add(t); // PARENT TABLE 

dd.Tables.Add(t0); // CHILD TABLE A

  

dd.Tables.Add(t1); // CHILD (CHILD) TABLE B - This is a child of table A

  

dd.Relations.Add(new DataRelation("Prop_Params", dd.Tables[0].Columns["PROPERTY_ID"], dd.Tables[1].Columns["PROPERTY_ID"])); 

  

   

dd.Relations.Add(new DataRelation("Section_Params", dd.Tables[1].Columns["PROPERTY_ID"], dd.Tables[2].Columns["PROPERTY_ID"]));

  

x_GRID.ItemSource = dd;

  

// end code snippet...

  

A few questions - I am in the DataLoading event (see questions in comments below)

void wpfgv_DataLoading(object sender, Telerik.Windows.Controls.GridView.GridViewDataLoadingEventArgs e) 

{

   var dataControl = (GridViewDataControl)sender; 

  

// 1. ParentRow != null tells me that it is a child table,
// but I need to know which CHILD TableName it is

// So that I can do different things for child table A and child (child) table B
// (like hide a column that child table A has but child table B does not.  
// How do I get the TableName of what dataControl is referring to
// (I could not seem to find it in my debugging watches)???

   if (dataControl.ParentRow != null) 

   {

      dataControl.ShowGroupPanel = false ;

  

// 2. I "think" because I have AutoGenerateCols = true, datacontrol.Columns = null
// so this crashes if left uncommented...

// just trying to verify my thinking on why it is null. 
  

dataControl.Columns["PROPERTY_ID"].IsVisible = false;  // will crash

  

// 3. x_GRID is the name of my GridView Control.  

// While this works, it only hides the PROPERTY_ID of the
// PARENT table column called PROPERTY_ID 

// and does NOT hide child columns of the same name (which is exactly
// the opposite of what I want to do).

// Is there a way without setting x_GRID.AutoGenerateColumns = false
// and binding each column

// in code or xaml to hide just columns of the children???

  

    x_GRID.Columns["PROPERTY_ID"].IsVisible = false ;  

   }

}

 

Thanks,

Hot to programatically expand some item? I would like to do something like:
Items[0].Items[4].Expand()

I know there is a method called ExpandItemByPath but i cannot guess how to use it and documentation says absolutely nothing about it.

Thanks in advance for any help

Hi,

I'm trying to give my price charts a 'Bloomberg' like look, i.e. I want to fill the area beneath the data series with a LinearGradientBrush.

I tried several options:
a) setting the PaletteBrushes like this:
           

b) setting Appearance.Fill on the AreaSeriesDefinition like this:

c) finally by creating a new style for the SelfDrawingSeries object and setting the BackgroundStyle:

All three approaches produced a visible effect (wow!) but it appears as if only the start color is used to fill the area of the series.

Is there something I'm getting or doing wrong or is this a bug?

Thanks,
Thorsten

Hello
            I have a context menu in my gridview, and i need when user do right click on grid view column then i want to select that pertiular column, how can i do it in telerik grid view? What type of event i can capture to do this or is there any another way to do this?

I have spent a few hours trying to figure out how to find a combobox in myWPF Gridview cell. I need to find it after gridview row is bound. There are no examples out there. It needs to happen in code behind Can anybody help? This is really driving me nuts.

I have a list of items that are generated based on user selections and I would like to display them on a timebar. I did create a converter to convert from my item to a RadLinearSparkline, but I can not figure out how to attach this Observable collection to display on the RadTimeBar. Is it only possible in the code behind?

Hey all,

I am writing an installer. It has a list of commands to execute and I need to show the progress.  I have a quite complex application that I am really using, so I created a sample app.  At first I was using the regular .NET 4 WPF DataGrid, but the .NET 4 DataGrid just wan't behaving stable.  See my recent post on MSND: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/e4eeb10b-8b27-4b26-a435-baa0ae4ea47a/

Anyway, my company has licensed Telerik, I was told, so I thought I would try the Telerik GridView.

I replaced the DataGrid with the Telerik GridView but I can't really even get started because the SelectedItem is not changing when the bound value changes.  It is a readonly bound value and I have it set to mode=oneway.  While debugging the NotifyPropertyChanged("CurrentCommand") is properly called.  This is one part that was working fine with the DataGrid.

Here is my sample app: DataGridExecutionListWithTelerik.zip

My overall goal is to Execute each command.  I must also do the following:
1. Show a progress spinner (which isn't in my sample but is working in my actual app) on the current item.
2. There are so many commands, there is scrolling.  So when it reaches the commands not visible, the GridView should scroll (I am using ScrollIntoView).  Then I need current command inprogress to always be visible.  When finished the item should stay scrolled to the bottom.

I need the SelectedItem to change when it changes in my ViewModel so the event fires so the ScrollIntoView function can be called.
