Hello Telerik team,
my name is Steve,
I’m new to your UI for WinForm controls, and to your forum.
I’m currently the
controls for my company, and got 3 (long) questions I like to ask
you.
So far me and my
colleges like what I could find out about using the Controls. The UI
Winform demo program made also a very positive impression to my
supervisor.
We are likely to get
a license, but requested to find a solution to my questions first.
Question 1:
I like to know why
there is a rad control replacement for the Winform Form class, but
no
replacement for the Winform Usercontrol Class. Can I use normal
Usercontrol classes
for making user controls, and still have full
Telerik UI support? Or is something replacing
the Winform
usercontrols and I just havent found it yet?
Question 2:
In Winforms I have
the problem that Trackbar Sliders can not be used as soon the Touch
Gestures are enabled.
I saw that I do not
have this problem when I do the same only using Telerik UI controls.
My question here is:
Is the problem that exists in WinForms, known to Telerik, and Telerik
found a solution to the Slider problem? Or is it just something weird
that only happens on my PC?
To understand best
what my slider problem is I made this demo application:
https://www.dropbox.com/s/pdxhza8hh5ximek/Touch_Example.zip?dl=0
The test program has
2 forms, one enables gestures following Mircosoft’s example code
for Windows Touch (source Windows 7 SDK example projects). The other
form does not
enable the gestures. Both forms have a trackbar slider
in it.
On the form where
gestures are on, its impossible to move the slider button via touch.
On the form that
does not enable gestures, it is possible without any kind of
problems.
Question 3:
I want to create a
image list control that supports touch panning left and rigth.
The control holds
for example 30 images, only 5 of them are seen. To see the remaing 25
images the user would pan left or right to move forward or backward
in the image list.
I create this kind
of control by using the ListView control and its LargeImageList
component.
I made a example
project that shows it:
https://www.dropbox.com/s/agx2e3ck4pb2x2e/Picture_Slider_with_Touch_demo.zip?dl=0
I tried to recreate
the control by using Teleriks Rad ListView control. So far I managed
it to
load and display my images in the list. What I fail to do are 2
things:
1. The controls
lists the images in a vertical list (pan up and down to move in it).
I haven’t found a way to make the list horizontal (so I can pan
left and right).
2. The list
automatical creates several rows by itself. I have not figured out
how to
force the control to just display a single row of images.
I uploaded what I
made got so far as well under this link:
https://www.dropbox.com/s/qo86k6vr99okgz2/Telerik_Listview_Test.zip?dl=0
To successfully
replicate the image list as in my Picture Slider demo I have this
questions:
1. Is the Rad
ListView control the right control to make a image slider list? Or do
you
suggest to use a different control to display a image gallery in
a win form.
2. To populate the
list I have to load all images to memory at start. This approach
anyhow
can become very memory consuming, if I have to load many
pictures. Does any Telerik UI
Control support a better approach,
where I have not to load all images at start?
All 3 example
projects are C# .NET 3.5 created in Visual Studio 2010. Zipped as a
Archive
and uploaded to my dropbox, so I can share a download link
with you.
I thank for any kind
of answer in advance. And I’m sorry for the length of my questions.
English is not my
native language.
Thank you for your time in advance and kind regards
~Steve
