I'm trying to display images from another server path using ImageGallery example below: (actually code with read from database loop)  anyway, if I put the images in the wwwroot folder path it works "~\images\" but when I point to a physical path it doesn't.

Protected Sub RadImageGallery1_NeedDataSource(sender As Object, e As Telerik.Web.UI.ImageGalleryNeedDataSourceEventArgs) Handles RadImageGallery1.NeedDataSource
TryCast(sender, RadImageGallery).DataSource = GetImageGalleryData()
End Sub

Private Function GetImageGalleryData() As DataTable
Dim table As New DataTable()
table.Columns.Add("Title", GetType(String))
table.Columns.Add("Description", GetType(String))
table.Columns.Add("ImageData", GetType(String))

table.Rows.Add("Image 1", "Description", "c:\images\Bale-0301201638060.jpg")
table.Rows.Add("Image 2", "Description", "c:\images\Bale-0301201638060.jpg")

Return table
End Function

Hi

Not necessarily a problem with the control, just asking if this problem has a solution.

I have a Radwindow that pops up modally and plays a YouTube video, trouble is when I close the window the content continues playing.

Can this be prevented?

Andy

I need to determine the row that a control is on the client side.

Anyone have an example that I can use?

Thanks

Dear All,

I am going mad with what looks to me as a silly thing; I get a "Selection out of range" Parameter name: value error on a page when I try to set the filter to a value that does not exist in the dropdown combo (see printscreen attached).

I am looking for a solution to avoid/catch this error. I cannot avoid people to filter for non-existing values so I need to catch this error and handle it properly but I don't know how... Can someone help ? The code of the page is as below:


And the code-behind:

Error occurs in Page_Load sub.

Hi Telerik Team
I am working on telerik asp.net scheduler.
When the resources(Left side in scheduler) is more than or equal to 65 it is giving error.
ERROR:
Specified argument was out of the range of valid values.
I already posted comment related to this in (http://feedback.telerik.com/Project/108/Feedback/Details/117889-specified-argument-was-out-of-the-range-of-valid-values) at 13 March 2015, 11:35.

Hi,
I have a RadEditor with StripFormattingOptions="AllExceptNewLines". Once the editor is loaded, if the user does a mouse-click followed by CTRL+V to paste html content, the html formatting is stripped successfully ONLY if there is a certain amount of time space between mouse-click and CTRL+V.
If the time gap is less, the following javascript exception is thrown and the formatting is not stripped.

Line: 2313
Error: 'parentNode' is null or not an object

We have users who do a quick Mouse+Click followed by CTRL+V and hence we see this bug quite often.
Please let me know if you have a workaround for this.
Any help is appreciated.

Thanks

When a certain combination of html is pasted into a RadEditor on our site, the webpage freezes and eventually we get the Long Running Script error.

The text I am test is nothing too strange:

For registration information Alicia Pierre Louis at <a href="mailto:asearles@misd.net">asearles@misd.net</a>.&nbsp; Join us for one more day of professional learning experience of bringing the Common Core Reading Standards to your K-2 classroom.&nbsp; We will take a look at the "brand new" MAISA Reading Units K-2. We will also include a half day session of leveled texts.

If I shorten it to the following, I don't get the error:

at <a href="mailto:asearles@misd.net">asearles@misd.net</a>.&nbsp; Join us for one more day of professional learning experience of bringing the Common Core Reading Standards to your K-2 classroom.&nbsp; We will take a look at the "brand new" MAISA Reading 

If I don't have both a mailto link and the double quotes, I don't get the error.

I was able to reproduce the problem in some sample code I found at http://www.telerik.com/forums/paste-plain-text-pop-up-causes-you-to-jump-to-the-top-of-the-page.

I'm using version 2014.3.1024.35.

So we have this RadGrid, it cannot be paged and appears unfiltered.  In some cases there are upwards of 1000 rows and in other cases upwards of 3000 rows.

In IE8 it causes the "Long running script, do you want to stop running scripts" message.

The only reason this grid is used here is because it is standard grid being used in the application, but it's use is minimal, some sorting and and a separate filter that retrieves the data again anyway.

So is there anything the grid may be doing that I can switch off to make it faster and less intensive?  I know nothing about Telerik controls or RadGrids?

The load on demand feature works well based on examples when using the standard combobox.items.add
How do we achieve the same when we are working with custom templates?

An example for Load on Demand with custom templates would be much appreciated.

Thank you.

I have a RadTreeView which has parent nodes which can be expanded to show its child nodes. These child nodes should then be able to be selected using checkboxes, but the parent nodes shouldn't. My issue is an accessibility one, as I wish to have the checkboxes associated with their text through a label, but the RadTreeView uses a <span> tag. The child nodes are populated when the parent node is expanded via the RadTreeView1_NodeExpand() method.

I believe the issue revolves around the parent/child situation as when creating a RadTreeView previously with no child nodes and a DataBind() I was able to declare a <NodeTemplate> which used checkboxes/labels, however this template does not seem to be used when adding the nodes via code behind using the Add() method with parents and children.

Is there a way I can add child nodes that adhere to a template I specify?

Here is my code, I have attached screenshots as well showing the association errors via WAVE.

No parent/children aspx:
<telerik:RadTreeView ID="RadTreeView1" runat="server" Skin="Skin_Telerik"
            CheckBoxes="false" MultipleSelect="true" SingleExpandPath="False"
            DataTextField="IDWithTitle" EnableEmbeddedSkins="false" DataFieldID="CategoryID"
            DataValueField="CategoryID" OnClientNodeClicked="ClientNodeClicked" Style="font-size:medium; white-space: normal;">
            <NodeTemplate>
                <asp:CheckBox runat="server" id="chkCategory" CssClass="rtChk" 
            Text='<%# String.Format("{0}: {1}", DataBinder.Eval(Container.DataItem, "CategoryID"), DataBinder.Eval(Container.DataItem, "Title")) %>' />
                <asp:HiddenField runat="server" ID="categoryID" Value='<%#DataBinder.Eval(Container.DataItem, "CategoryID")%>' />
            </NodeTemplate>
</telerik:RadTreeView>

No parent/children VB:
    RadTreeView1.DataSource = oList
    RadTreeView1.DataBind()


Parent/children aspx: 
<telerik:radtreeview id="RadTreeView1" AccessKey="M" TabIndex="1" runat="server" skin="Skin_Telerik" checkboxes="true"
                    multipleselect="true" singleexpandpath="False" datatextfield="Title" da enableembeddedskins="false"  
                    datafieldid="ID" datafieldparentid="ParentId" datavaluefield="ID" onclientnodeclicked="ClientNodeClicked" 
                    onnodeexpand="RadTreeView1_NodeExpand" Style="white-space: normal;" CheckChildNodes="true" Font-Size="Medium"/>

Parent/children VB:


Any help would be much appreciated!
