Scrolling problem

[Alexander]

I made a simple example:

public class TestData       {           public static IEnumerable<TestData> Generate(int count)           {               var rnd = new Random();                 for (int i = 0; i < count; ++i)               {                   yield return new TestData()                   {                       SomeDtmProperty = DateTime.Now,                       SomeFltProperty = (float)rnd.Next() / (float)rnd.Next(),                       SomeIntProperty = rnd.Next(),                       SomeStrProperty = new string((char)((rnd.Next() % ((int)'z' - (int)'a')) + (int)'a'), rnd.Next() % 20 + 10)                   };               }           }             public string SomeStrProperty { get; set; }           public int SomeIntProperty { get; set; }           public DateTime SomeDtmProperty { get; set; }           public float SomeFltProperty { get; set; }       }  public partial class Window1 : Window

{

ObservableCollection<TestData> m_TestDataCollection = null;

public Window1()

{

InitializeComponent();

InitData();

gvTest.ItemsSource = m_TestDataCollection;

}

void InitData()

{

m_TestDataCollection = new ObservableCollection<TestData>(TestData.Generate(100));

m_TestDataCollection.Add(

new TestData()

{

SomeStrProperty = "The last row"

});

}

}

<Window x:Class="WpfApplication6.Window1"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="Window1" Height="300" Width="500">

<Grid>

<telerik:RadGridView x:Name="gvTest"/>

</Grid>

</Window>

Steps to reproduse:

1) Run this code

2) Scroll the grid down using right scrollbar

3) last row (marked "The last row") is half-visible (or invisible at all), despite of right scrollbar is bottom down (if you can't reproduce please set some another value in generate method)

4) Now scroll using mouse wheel. Everything is OK.

PS. I use Q3 without SP1 (will migration to SP1 fix this?)

Hi Alexander,

I tested with the Q3 assemblies (no SP) and was able to reproduce your problem. With the SP assemblies I was unable to reproduce it, even using several different values in the Generate method, so the upgrade to SP will fix the problem.

All the best,

Hi !

I have the scrolling issue with the latest internal build (2012.3.1210)
attaching my screenschots (1 - before expand details, where scrolling works fine, 2 - after expanding details at the very bottom record). to reproduce it you need to create GridView with details template and expand some of them. Then scroll down and view the very bottom of the grid. Latest records are not visible and i unable to scroll down to view them.

Have attached the example in the different ticket, but the source code is the same.
