Adding Menu Item Images from Embedded Resources

I'm building menus in code. I need to be able to set the menu item image, but the only way I see to do this is by providing a URL string.

The problem is that the images are embedded resources, not separate files on the file system. So I would like to be able to do something like...

Assembly assembly = Assembly.GetExecutingAssembly();

Stream imageStream = assembly.GetManifestResourceStream(ResourceName);

menuItem.ImageUrl(or other property) = new Bitmap(imageStream);

Obviously that won't work. Is there a way to do this by providing the image data directly rather than a URL to a file?

Bar Chart has additional Entries

I'm using the bar chart. My current dataset has 8 entries in it, dates in the range of Sept 2nd through Oct 2nd. When I display the chart I expect there to only be 8 sets of bars. Instead it is showing every date in between. I don't want that.

Menu inside noscript tag

Hi,

I have implemented a two level radmenu on our website and trying to render a secondary menu in case javascript is disabled on client's browser. I want this second menu to appear under the main menu only if javascript is disabled on the browser, so I am rendering this second radmenu inside <noscript> tag. It works fine as expected when javscript is disabled, and also works fine (menu doesn't appear) if javasript is enabled.
However, I get a javascript error (obviously when it's enabled) :
Error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.
Parameter name: element
By looking at the Call Stack of the browser's developers tool, I think it is due to the following script that gets rendered automatically by telerik on the page (I have trimmed down the syntax)

Sys.Application.add_init(function() {
$create(Telerik.Web.UI.RadMenu, {"_childListElementCssClass":null,"_enableItemImagesPreloading":true,"_flow":0,"_skin...;
});

It is definitely something to do with radmenu inside <noscript> tag, as if I render it without this tag, and with javascript enabled on browser, everything works fine.

I am using IE 8 with compatibility mode turned on.

Thanks in advance

Multiline Chart Title

Hello Telerik,

So is there any way to split large chart title in multiple lines using telerik HTML charts?

[Solved] Cascading comboboxes in RADGRID edit form

Hello everyone,

Can some one please help in solving this issue, I have a radgrid and using automatic updating/deleting/inserting and also using "edit form" provided by the grid. I have 2 comboboxes in my editform that i would like them to be related to each other. One combobox is the country the other is "state/province" depending if ur in Canada or the US. So if u select the country then the other combobox gets filled with appropriate values. I have looked every where and can't find a solution.

Thanks in advance for any help.

Reda.

Change Image in Anchor on _ItemDataBound

I have a grid and one of the cells is set as such

<rad:GridTemplateColumn AllowFiltering="False" UniqueName="EditLink" Groupable="false">

<ItemTemplate>

<a href="EditClient.aspx?ClientID=<%# Eval("ClientID")%>">

<img alt="Edit Client" border="0" src="" title="Edit Client" />

</a>

</ItemTemplate>

<HeaderStyle Width="20px" />

</rad:GridTemplateColumn>

What I am trying to do is set the image source based on a value in the grid at run time.

I assume ItemDataBound is the way to go but how do I get down to the image of the anchor in the item template

[Solved] shorten display name?

After selecting a file for upload, is it possible to shorten the displayed filename?

So if a user selects veryveryverylongfilename.pdf, can I display

veryveryverylong... [x remove]

but still save it as veryveryverylongfilename.pdf. I have a limited space where I have placed the control and if the filename is too long my formatting gets thrown off.

thnx

Rad Grid with dynamic columns

Hi,

I have a requirement like the first column list out the features and the other columns lists out the user selected products and there by user can compare the features against opted products. Since the product columns are dynamic, I have confusion on how to implement. What is the best approach ?

Thanks,

Ajax communication between a user control and a RadGrid

Hello,

I have a Radgrid bound to a data source:
<radG:RadGrid ID="grdOthers" runat="server" DataSourceID="odsOthers"...>
..and a user control which contains a complex popup for adding a new record to the data source
<ucAutreActivite:AutreActivite ID="PopupAutreActivite"...>
In the user control the button which does the job:
<asp:ImageButton ID="btnValiderPopupAjouterActivite"...>

I also manually set in the user control the Ajax context between the button and the parent grid (which is a property of the user control), and it seems that it appears well in the View Source code:
window["RadAjaxManagerPlanningGrid"] = new RadAjaxManager(...{InitControlID : "PopupAutreActivite_btnValiderPopupAjouterActivite",UpdatedControls : [{ControlID:"PopupAutreActivite_AjouterActivitePopup",PanelID:""},{ControlID:"grdOthers",PanelID:""}]}...)

The problem is although that, after pressing the button which inserts a new value (and this works OK), the grid is not refreshed.
Am I missing something?

Thank you

RadButton OnClick event won't fire

Ok, so I have a RadButton on a page and in the code-behind all that happens is a simple change of the selected view of a RadMultiPage. The problem is that the code never executes. I have no idea what is going on and can't figure out why the button won't work. I have another page that does the same thing and the button works fine, but on this page nothing happens. I click the button and it just goes back to the top of the page like you would see for an <a href="#"></a> tag. Any ideas?
