Telerik RadPageview Right-to-Left Layout Arrow Keys - telerik

Question

I have a RadPageview in Strip Mode and I want my program to had support a right-to-left language. When I changing the Right-to-Left Property to true it works fine. but when I run my program and use Arrow Keys (Left or Right) it doesn't work correctly. Left key goes to Right and Right key goes to Left. How can I fix it?

Telerik answered my question:

the possible solution that I can suggest is to create a custom RadPageViewStripElement and override its IsNextKey and IsPreviousKey methods on a way to reverse the previous/next navigation as follows:
public class CustomPageView : RadPageView
{
public override string ThemeClassName
{
get
{
return typeof(RadPageView).FullName;
}
}
protected override RadPageViewElement CreateUI()
{
switch (this.ViewMode)
{
case PageViewMode.Strip:
return new CustomRadPageViewStripElement();
default:
return base.CreateUI();
}
}
}
public class CustomRadPageViewStripElement : RadPageViewStripElement
{
public CustomRadPageViewStripElement()
{
}
protected override Type ThemeEffectiveType
{
get
{
return typeof(RadPageViewStripElement);
}
}
protected override bool IsNextKey(Keys key)
{
if (this.RightToLeft)
{
if (key == Keys.Left)
{
return true;
}
else
{
return false;
}
}
return base.IsNextKey(key);
}
protected override bool IsPreviousKey(Keys key)
{
if (this.RightToLeft)
{
if (key == Keys.Right)
{
return true;
}
else
{
return false;
}
}
return base.IsPreviousKey(key);
}
}

I fix it programmatically by using ProcessCmdKey of form.
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == (Keys.Right))
{
int x = radPageView1.Pages.IndexOf(this.radPageView1.SelectedPage) - 1;
if (x < 0)
x = radPageView1.Pages.Count() - 1;
else if (x >= radPageView1.Pages.Count())
x = 0;
radPageView1.SelectedPage = radPageView1.Pages[x];
return true;
}
else if(keyData == Keys.Left)
{
int x = radPageView1.Pages.IndexOf(this.radPageView1.SelectedPage) + 1;
if (x <= 0)
x = radPageView1.Pages.Count() - 1;
else if (x >= radPageView1.Pages.Count())
x = 0;
radPageView1.SelectedPage = radPageView1.Pages[x];
return true;
}
return base.ProcessCmdKey(ref msg, keyData);
}
