Dynamic Slider crazy

[Daniel Botero Correa]

Hi everybody,

I've a problem with a slider control, the problem is the next:

When i initialize the Slider control with the code below, it's good bound but when i do postback on my page, the slider change the positions and values' RadSliderItems, Example:

|  1  |  2  |  3  |  4  |  5  |  6  |  7  |  8  | -> item selected = 1 week.SelectedItem.Value  = 1

i do post back (Change value item 1 = 2, why? i don't know)

|  1  |  2  |  3  |  4  |  5  |  6  |  7  |  8  | -> item selected = 1 week.SelectedItem.Value = 2

i do post back (Change position all items and change value item 2, why? i don't know)

|  2  |  3  |  4  |  5  |  6  |  7  |  8  | 1 | -> item selected = 2 week.SelectedItem.Value = 3

So, i'm not never sure about values' items and the position change...

Thanks....

Code ASP:

<telerik:RadSlider ID="week" runat="server" AnimationDuration="400"
       Height="70px" ItemType="item" Width="350px" >
</telerik:RadSlider>

Code CS:

   protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            initialize_week();
        }
    }


    public void initialize_week()
    {
        for (int i = 7; i >= 0; i--)
        {
            String value =
                    DateTime.Now.AddDays((-7) * i).ToString();
            RadSliderItem item = new RadSliderItem(
                DateTimeTreatment.GetWeekNumber(
                    DateTime.Now.AddDays((-7) * i)).ToString(),value);


            week.Items.Add(item);
            week.DataBind();
        }
    }

Hello Daniel Botero Correa,
We are aware of this problem - it is actually a problem in the SelectedItem and SelectedItems properties. Until we fix the problem, you should use the following approach to get the value of the selected item, instead of SelectedItem.Value:

SelectedItemValue.Text = week.Items[week.Value].Value;

it's strange but that works.
