Menu item set disable client side

Hi guys,

I am talking about contextmenu. I am trying to make a MenuItem not visible.
Let's say a user right-click on a button, a ContextMenu appear and give him some choises.
I have a javascript code that will determine what options (MenuItem) will be available for him.
I have managed to enable/disable the menuitems following this library but I can't figure out how to make the MenuItem not visible (rather than disabled).

Thanks in advance.

Conditional Formatting of an ImageColumn

I have a grid which has a number of databound columns (all created in code)
I have carried out a number of conditional formatting operations for example

Private Sub radgrid_databound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)

'Is it a GridDataItem

If (TypeOf (e.Item) Is GridDataItem) Then

Dim dataBoundItem As GridDataItem = e.Item

If Left(dataBoundItem("ChangeFromPrevious").Text, 1) = "-" Then

dataBoundItem("ChangeFromPrevious").ForeColor = Color.Red

End If

End Sub

I have now added a gridimagecolumn to my table which I want to display an arrow image pointing up or down depending if my databound column "changeFromPrevious" is positive or negative.

I am hoping to simply change the imageURL of the gridImageColumn, but I am unclear how and from which event I should do this.
ie do I do this on the databound condition dataitem, if so how do I access the imagecolumn.imageurl
or
do I do this as each image in the GridImageColumn is created, if so how do get the databound item "changedfromPrevious" to apply conditions.
or is there a better approach?

Thanks

programmatically adding RadContextMenu

Hi
I wanna create a custom server control (from CompositeControl base) that has context menu by default
by something like this :

   protected override void CreateChildControls()
   {
   base.CreateChildControls();

   Panel pnl = new Panel();
   pnl.ID = "pnl";
   pnl.Width = Unit.Pixel(100);
   pnl.Height = Unit.Pixel(100);
   pnl.BackColor = System.Drawing.Color.Black;
   this.Controls.Add(pnl);

   RadContextMenu cntMenu = new RadContextMenu();
   cntMenu.ID = "cntM";
   RadMenuItem mItem = new RadMenuItem("Delete");
   cntMenu.Items.Add(mItem);
   ContextMenuElementTarget target = new ContextMenuElementTarget();
   target.ElementID = pnl.ClientID;
   this.Controls.Add(cntMenu);

   }

But it does not work
Is it possible to add ContextMenu dynamically ?
Have I done something wrong ?

Thank you very much for your feedbacks

Can not find reference to Telerik Control

Hello,

I have Telerik's WinForms controls installed, they work fine. Now want to use Telerik's AJAX controls, I could not find them so I've already tried to (re?)install them. But I still can't find them.

What is their name supposed to be in the "Add Reference" windows of Visual Web Developer Express ?
What should be their 'Assembly name' in the "Choose Toolbox Items" window ?

Thank you for you help.

When I supply data the row heights change as I add items.

The first item occupies the entire height availalbe.

The second add makes the two rows take 50%.

Three a third etc until I reach four or five. Then the size is constant.

What am I missing?

Possible to have custom scroll button size?

I have a custom skin, and cannot seem to get my custom arrows to show. I'd like bigger arrows for people browsing on touch devices. Is this possible? I tried amending the background-position values in the skin css, but to no avail. Currently, the images used seem to be coming from a fixed place in the sprite image, but not where I'm trying to point in the css.

NB: Even though this the RadTabStrip has ScrollChildren set to true, the tabs wrap in IE9 and Chrome, though never in Firefox (all Win7). Note that sometimes the tab strip becomes a single line strip as I remove and add tabs.

Any help would be welcome.

See an example at http://an.rsl.wustl.edu/radcontrolswebapp1/default.aspx

Here is part of my custom skin css (named "an12")

.RadTabStrip_an12 .rtsLI,

.RadTabStrip_an12 .rtsLink

{

color: #000;

font: 12px/26px "Segoe UI", Arial, sans-serif;

}

.RadTabStripLeft_an12 .rtsSeparator,

.RadTabStripRight_an12 .rtsSeparator

{

background: #828282;

}

/* <disabled tabs> */

.RadTabStrip_an12 .rtsDisabled

{

color: #aaa;

}

/* </disabled tabs> */

/* <scrolling arrows> */

.RadTabStrip_an12 .rtsNextArrow,

.RadTabStrip_an12 .rtsPrevArrow,

.RadTabStrip_an12 .rtsPrevArrowDisabled,

.RadTabStrip_an12 .rtsNextArrowDisabled

{

background-image: url('TabStrip/TabStripStates.png');

height:48px;

width:32px;

}

.RadTabStrip_an12 .RadTabStripTop_an12 .rtsNextArrow { background-position: 0 -288px; }

.RadTabStrip_an12 .RadTabStripTop_an12 .rtsPrevArrow { background-position: -32px -288px; }

.RadTabStrip_an12 .RadTabStripTop_an12 .rtsPrevArrowDisabled{ background-position: -64px -288px; }

.RadTabStrip_an12 .RadTabStripTop_an12 .rtsNextArrowDisabled{ background-position: -96px -288px; }

/* </scrolling arrows> */

Help with ajaxrequest

I have a control which is an html table of links. We turn off various rows in this table based on user permissions and/or the state of the data. Need help with getting the control to render after we use a RadWindow.

I think I'm pretty close. There are two links which are kind of the on-and-off for this function. Clicking whichever link is showing pops up a RadWindow; if the user hits the 'right' button, we want to make that link invisible and show its opposite number.

I've got the client-side handling of the RadWindow closing working, which kicks off an ajaxrequest as such:

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest('ShowRDDAssignmentRow');

I've got the handler in my code-behind properly looking at the parameter and setting each table row's visibility properly. I can't figure out how to configure the RadAjaxManagerProxy to recognize this request and tell the control it's been updated.

I've tried setting the AjaxControlID to the link, the Proxy, and even manually in code-behind to the Manager (this being a control, of course that's not local), but I can't get the table to re-draw. I've got a RadAjaxPanel enclosing my html table, and that panel is the updated control, so my markup is like this:

<telerik:RadAjaxLoadingPanel ID="loadingPanel" Skin="Default" runat="server" />

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManagerProxy">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="ajaxPanel" LoadingPanelID="loadingPanel" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

Seems as if I'm missing something obvious.

Thanks,

Scott
