I was implementing a treeview in a combobox nearly identical with the demo here:
http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/treeviewcombobox/defaultcs.aspx?product=treeview

The implementation is .NET in an update panel running in Chrome. I found that the the tree view nodes would display corrrectly and would collapse as expected. Once collapsed they would not re-expand. I examine the <UL> tags in the Chrome developer tool and discovered that the nodes had "display: none" style tags that were inserted on collapse but not removed on expand.

I found, via trial and error, that adding a expandanimation-type="None" attribute to the RadTreeView resolves the problem. Actually, I slapped my head on finding that as we have seen that same behavior in our other RadTreeView uses and I had forgotten. It's a nasty little problem.

The demo has ExpandAnimation-Type="None" CollapseAnimation-Type="None" on the container RadComboBox, but NOT on the RadTreeView and yet it works. Mine would only work when the expandanimation-type was also on the RadTreeView.

Your demo, by the way, works fine in Chrome as it. So clearly there is some odd combination of JS and .NET on my page that makes this happen. I point this out only as a possible help to someone else who might be tempted to punch a monitor as I was. This little flaw is not in the forum as far as I was able find. Thanks.

Multi Characters AutoCompleteSeparator in RadComboBox

Multi Characters AutoCompleteSeparator in RadComboBox:
---------------------------------------------------------------------------
I need to have 2 characters as the "AutoCompleteSeparator in RadComboBox". I know that you can use [AutoCompleteSeparator=";|" to have multiple 1 character [; and |] separators. But I need to have [AutoCompleteSeparator=" " 2 white spaces acting as 1 separator.
For example:
My Item1 My Item2 My Item3
[please note that between My Item1 and My Item2 there are 2 whites spaces which I want to use as a separator so that I can get the following:]
My Item1
My Item2
My Item3
Is it possible?

Display issue when client resize.

Hi all,

Here it is :

I use JavaScript to resize on client side a "div" element which contain a RadGrid, and another one which contain a RadChart.
Here is my JS function :

function ToggleDiv(Flag)

{

if (Flag == "first")

{

document.getElementById('gridZonesLosses').style.display = 'block';

document.getElementById('chartZonesLosses').style.display = 'none';

document.getElementById('gridZonesLosses').style.width = "100%";

}

else

{

document.getElementById('chartZonesLosses').style.display = 'block';

document.getElementById('gridZonesLosses').style.width = "17%";

document.getElementById('gridZonesLosses').style.cssFloat = "left";

document.getElementById('gridZonesLosses').style.display = 'block';

document.getElementById('chartZonesLosses').style.width = "82%";

}

It show and hide perfectly my components, and do the resize.
But when it perform it, there is some issues with FireFox 13.0. The horizontal scrollbar is not adapted to the new radgrid size, except if i refresh the page by cliking on a button or just execute an AJAX request. Please find in attachment 2 printscreen of the issue and the way it appears.

Any solution ?

Javascript Error- Unable to get value of the property 'indexOf'

Hi,
I am trying to implement the Radscheduler using "External edit in raddock" as in http://demos.telerik.com/aspnet-ajax/scheduler/examples/raddock/defaultcs.aspx
I am getting a javascript error as "Microsoft JScript runtime error: Unable to get value of the property 'indexOf': object is null or undefined" while clicking on a time slot and selecting 'new appointment'.
I have already put this issue in the forum before also,but couldn't get it resolved.Even though this is a duplication in the thread,thought of starting it as a new thread as earlier thread was continuation of different thread with a different subjetct.So if someone has faced same issue before,they could help me out in this.

The only change I have made from the demo is that ,I have changed session datasource with sql datasource.Please find my markup for the same.
Also I have recorded a video showing the error in the link http://www.screencast.com/t/z8EbrNHnBDH

Image inside radgrid doesn't refresh after rebind

Hi,

I have a rad grid with a template column that contains image:

<telerik:GridTemplateColumn

HeaderText="Status" HeaderStyle-Width="50px" ItemStyle-Width="16px"

UniqueName="SensorConnectionStatus" AllowFiltering="false">

<asp:Image ID="StatusImage" runat="server" Width="16px" Height="16px"/>

</ItemTemplate>

</telerik:GridTemplateColumn>

In the databound column I have the following code:

        if (e.Item is GridDataItem)
        {
            GridDataItem myGridItem = (GridDataItem)e.Item;
            bool IsOnlineSensor = IsOnline(DataBinder.Eval(e.Item.DataItem, "SensorConnectionStatusCode"));

Image image = (Image)myGridItem["SensorConnectionStatus"].FindControl("StatusImage");

            if (IsOnlineSensor)
            {
                image.ImageUrl = "~/Images/Design/a.png";
                image.ToolTip = "Online";
            }
            else
            {
                image.ImageUrl = "~/Images/Design/b.png";
                image.ToolTip = "Offline";
            }
        }

I have a refresh button that calls the client side function that should rebind the grid:

function RebindCxSensorsGrid() {

var masterTable = $find("<%= gvSensors.ClientID %>").get_masterTableView();

masterTable.rebind();

}

The problem is that I have an online sensor with the image a.png, but after I press the refresh button it should change to offline and display b.png in the grid.
I put a breakpoint and I see that the data is correct, but the image didn't change...

Do you have any idea what am I doing wrong?
If I load the page again, the icon changes.

Thanks.

Rotator and WrapFrames with Buttons

Consider the example on http://demos.telerik.com/aspnet-ajax/rotator/examples/default/defaultcs.aspx and change the RotatorType to Buttons and the Width to 1000px.
Is there any solution how to have a smoother moving when clicking on the rotator buttons?

When WrapFrames is disabled, the rotation seems to look good, but we indeed need the WrapFrames functionality set to true.

Thanks in advance

GridBinaryImageColumn - no hair left!

Hello,

I am really struggling on this. A quick solution would be great before I go crazy, thanks.

I have a problem trying to get images working in RadGrid. I am using an existing SQL table (SQL 2005 Developer) which has product images stored as column type image. These display fine in Winforms radgrid controls. Under asp.net though I keep getting errors about invalid parameters.

The exception is shown

Parameter is not valid.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
