Shared sliders

Hi,

I need to put circa 20 sliders onto one page - a survey. I'd prefer to somehow use one shared slider - similar to with the calendar popup code. Is there an easy way to do this? Same goes for the slider items - worst case I suppose that I can add them from the server code but would prefer that I could use a shared calendar.

Any help much appreciated.

Cheers,

Jon

Problem to make disappear GridTempleColumn but ONLY for some lines

I have a complex problem:

I have in my Grid a GridTemplatecolumn which displays the text " rapport " but this text must be visible only for some lines

The condition to enable or disable the visibility is within the second if

protected void GridDisplayOldRDV_ItemDataBound(object sender, GridItemEventArgs e)

{

HiddenField HiddenFieldIdParticipant = e.Item.FindControl("HiddenFieldIdParticipant") as HiddenField;

Utilisateur utilisateur = (Utilisateur)Session["utilisateur"];

if (HiddenFieldIdParticipant != null)

{

if (utilisateur.idUtilisateur.ToString() != HiddenFieldIdParticipant.Value.ToString())

{

GridDisplayOldRDV.MasterTableView.GetColumn("Debriefing").Visible = false;

}

Right now , my problem is with this line :

GridDisplayOldRDV.MasterTableView.GetColumn("Debriefing").Visible = false;

The column disappears everytime...

I hope i'm clear enough

Thanks in advance for your help

Backspace button - radwindow

Hi,
I want to disable bacskapce (going to previous page) in radwindows.
So I added js code:

function getKey(keyStroke) {

var t = window.event.srcElement.type;

var keyCode = (document.layers) ? keyStroke.which : event.keyCode;

var keyString = String.fromCharCode(keyCode).toLowerCase();

var leftArrowKey = 37;

var backSpaceKey = 8;

var escKey = 27;

if (t && (t == 'text' || t == 'textarea' || t == 'file')) {

//do not cancel the event

} else {

if ((window.event.altKey && window.event.keyCode == leftArrowKey) || (keyCode == escKey) || (keyCode == backSpaceKey)) {

alert(keyCode);

return false;

}

}



<body onkeydown="getKey()">...

but it doesn't work (alert is showing, but "false"doesn't stop going to previous page). Is any specific approach in radwindows to achieve the target?
Thanks.

Value databinding issues

Hi,

When using the slider I am noticing some odd behaviour. I have a set of criteria 1-5 and in the database I store which one of them was chosen. Now If I use the code as below with the database value of 1, the second entry in the list is selected, setting the value in the database to 0 (which in practice it should never be) causes the first item to be selected. It's almost as if the slider is treating the value as a 0 based array index.... Any ideas? Code follows:

<telerik:RadSlider ID="uxOQC_1" runat="server" DbValue='<%# Bind("OQC_1") %>' MinimumValue="1" MaximumValue="5" ItemType="Item" TrackPosition="Center">

<Items>

<telerik:RadSliderItem Text="Strongly disagree" Value="1" ToolTip="Strongly disagree" runat="server"></telerik:RadSliderItem>

<telerik:RadSliderItem Text="Disagree" Value="2" ToolTip="Disagree" runat="server"></telerik:RadSliderItem>

<telerik:RadSliderItem Text="Neither agree nor disagree" Value="3" ToolTip="Neither agree nor disagree" runat="server"></telerik:RadSliderItem>

<telerik:RadSliderItem Text="Agree" Value="4" ToolTip="Agree" runat="server"></telerik:RadSliderItem>

<telerik:RadSliderItem Text="Strongly agree" Value="5" ToolTip="Strongly agree" runat="server"></telerik:RadSliderItem>

</Items>

</telerik:RadSlider>

Strange side-effect when a RadCombo box is placed in div tag that uses the float: left; style

Recently I had the need to put a RadComboBox on a page to display a drop down and noticed something quirky which made me have to rethink my layout to work around this odd issue.

If I place a RadComboBox as follows, everything works normal:

<div>

<telerik:RadComboBox ID="ComboBox" runat="server">

... items

</telerik:RadComboBox>

</div>

But the second I add "float: left;" as a css style as so then the RadComboBox behaves a little differently:

<div style="float: left;">

<telerik:RadComboBox ID="ComboBox" runat="server">

... items

</telerik:RadComboBox>

</div>

What normally happens is you are able to highlight and/or click anywhere on the combobox and your items will drop down so you can select something. With float: left; enabled in the div tag all of a sudden I can no longer drop down the combobox if I highlight and click on the image area of the combobox. That is the little down-arrow icon. I can highlight/click in the text area, but the area off to the right displaying the arrow icon becomes useless.

The only solution I have found to work is to avoid this scenario and rethink the layout.

Is anyone else able to replicate this quirk? I am using ver: 2010.3.1109.40

Thanks!

Telerik RadGrid Display Issue

Hi,

We are using latest version of Telerik.Web.UI.dll (2011.2.1011.40) in our project and currently i am facing an issue related to Telerik RadGrid display!

During the initial load, grid displays as expected but after a post back (i.e. click of Edit button in grid which displays another panel in same page and click of Cancel button in the displayed panel) the grid displays without any Skin/Theme. Attached is the screen shot for reference.

In another screen, this problem occurs during initial load of the grid.

Please let me know if i am missing out anything and help me resolve this unique issue.

Thanks,
Krishna Samaga B.

RenderControl() issues

Hello guys,
I have a web control that holds RadDockLayout control as a property:

public class DockZonesContainer : Control

{

    private Telerik.Web.UI.RadDockLayout _layout;

In my control I am trying to dynamically create DocZone and add it to the RadDockLayout control.
when I'm trying to load my page I get this error:

Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

on this source code:

public override void RenderControl(HtmlTextWriter writer)

_layout.RenderControl(writer);

}

BTW
when I try to add a simple asp label. I got no errors.

Please advise.
Thanks
