Is there a list of system colors or css or template or cheat sheet that lists what the fill colors are for a given (Vista) series pallet?

I have two charts on the same page and on one of them I need to set the fill color programmatically. I figured this out and it works great. However, I need the colors to be similar to the other chart using the Office2007 skin and the Vista pallet colors for the series.

I would really like to get the list of main and secondary colors for each item in the "Vista" pallet. Is this available?

Thanks,
Craig

Delay loading the DetailGrid

Hello Telerik Team,

We have updated our Telerik controls to 2011.3.1115.40 from 2008.3.1314.20 this week. Until last week the RadGrids and DetailGrids(1 or 2 secs) were loading quick. But now, it takes quite a while for the DetailGrids(8 to 10 secs) to load.
We are using Webservices to load the Data to the grids. What could be the possible reason for the delay. Are there any techniques to improve the speed.
Also I have gone through your links as suggested in this link : http://www.telerik.com/community/forums/aspnet-ajax/grid/radgrid-and-performance-intended-usage.aspx , but could not find any solution.

We are currently using .Net Framework 4.0 and AjaxToolkit : 3.0.20820.16598

I tried to upgrade the AjaxToolkit to 4.1.51116.0 after I installed the new Telerik controls, but one of my pages throws a javascript error saying " Microsoft JScript runtime error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll."

I have tried giving both ScriptManager & ToolkitScriptManager , but none of them solved my problem.

It will be really great if someone could help me regarding this.

Thankyou,
Swetha

custom validation

How do I use a customValidator With RadGrdi to validate ALL of the editable fields in a grid when in-line editing is used. In such a case, I don't set ControlToValidate in the CustomValidator, so in my ServerValidate Event, I don't know how to obtain the values being updated. The example shown in

http://www.telerik.com/help/aspnet-ajax/grid-validation.html

only pertains to validating a single field.

Private Sub custVal_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles custVal.ServerValidate

args.IsValid = ValidatedConfiguration()

End Sub

Private Sub ValidatedConfiguration()

' How do I access the updated values here?

End Function

Header Context Menu on RadGrid

I am trying to use the header context menu of the radgrid. My requirements ask me to only show certain 'main' columns and hide certain 'additional' columns in the grid, when it is first loaded. Users should then be able to click on the header context menu and pick whichever additional columns they wish to see. This also means that users should only see the 'additional' columns, for selecting and unselecting, in the Header context menu. Is this possible? If so, how?

Thanks!

BackColor property not working

I'm reading the appointments form a datatable. Here is my code:

List<MyClass> myObjects = (from e in myEntities.Mytable where
e.DateFrom >= schedulerInfo.ViewStart &&
e.DateTo <= schedulerInfo.ViewEnd
select e).ToList();

List<Appointment> appointments = new List<Appointment>(myObjects.Count);
foreach (MyClass e in myObjects) {
Appointment a = new Appointment();
a.ID = e.ID;
a.Subject = e.Description;
a.Start = e.DateFrom;
a.End = e.DateTo;
a.BackColor = System.Drawing.Color.Yellow;
appointments.Add(a);

and when I run it, it isn't yellow!

ResolveRootDirectoryAsTree is calling multiple times and files are not populating in ImageDailog list

Using Telerik version 2011.3.1115.35, facing a problem when using DBContentProvider.cs, thats is
RadEditor1.ImageManager.ContentProviderTypeName = typeof(DBContentProvider).AssemblyQualifiedName;

On debug found that ResolveRootDirectoryAsTree is calling multiple times and files are not populating in ImageDailog list for ViewPaths = "Root", however returnValue contains the list of retreived files already uploaded.
Note:in old version same code working for IE8 in compatibility mode.

public override DirectoryItem ResolveRootDirectoryAsTree(string path)
{
      DirectoryItem returnValue =
                    new DirectoryItem(GetName(path), GetDirectoryPath(path), string.Empty, string.Empty, fullPermissions, GetChildFiles(path),
                    GetChildDirectories(path));

      return returnValue;
}

Why ImageDialog not showing the files and upload button also remains disabled

Should I Put a RadAjaxManager inside a RadWindow

Hi,

This is more of a theoretical question as I plan a page. Here is the situation:

I want a host page containing several Telerik controls, include RadAjaxManager.
RadWindows will be launched from this page via button clicks and context menus.
I like to launch my RadWindows via client side.

Now here is the gig: Some of my windows themselves have some content that should be ajaxified within the window itself. For example, if this was a stand alone page, I would add a RadAjaxManager to the page to control the interaction between controls. In this context, I do not care about updating controls on the host page -- just controls contained on the RadWindow itself.

However, this being a page launched as a RadWindow (essentially an iFrame, I believe) I'm concerned with the best practice to do this. Does it make sense to have a RadAjaxManager on the host page, and a second RadAjaxManager on the iFrame itself. Will they fight? I've noticed some posts where it says to have the RadWindow update itself via the RadAjaxManager on the host page, but that seems a little disconcerting in that I won't have a lot of control of the update order on the RadWindow.

So, what's the best practice here?

Thanks so much!!!!

Jim

Setting Title and TitleIcon in OnCallbackUpdate?

Hi,

I'm displaying a RadNotification control from within an async postback. The markup for the RadNotification looks like this:

<telerik:RadNotification ID="AddToCartNotification" runat="server" Animation="Fade" AutoCloseDelay="5000" ContentIcon="" Height="100px" Opacity="80" Position="Center" Skin="Forest" Width="300px" EnableRoundedCorners="True" EnableShadow="True" LoadContentOn="EveryShow" oncallbackupdate="AddToCartNotification_CallbackUpdate" Title="Add to Cart Result" />

My code behind looks like this:

protected void OnVideoRepeaterItemCommand(object source, RepeaterCommandEventArgs e)

{

switch (e.CommandName)

{

case "AddToCart":

{

AddItemToCart((string)e.CommandArgument);

break;

}

private void AddItemToCart(string productSku)

{

ShoppingCartUtilities.AddToCartResult result = ShoppingCartUtilities.AddItemToCart(productSku, 1, 1);

string caption = "";

string msg = "";

string icon = "";

if (result == ShoppingCartUtilities.AddToCartResult.ItemAddSucceeded)

{

icon = "info";

caption = "Item Added";

msg = "Item successfully added to cart";

}

else if (result == ShoppingCartUtilities.AddToCartResult.ItemAddFailedMaxItemCountReached)

{

icon = "warning";

caption = "Maximum Count for Item Reached";

msg = "Only one copy of this video can be added to your cart";

}

else

{

icon = "deny";

caption = "Unable to Add Item to Cart";

msg = "Add to cart failed. Sorry for the inconvenience";

}

string value = string.Format("{0}|{1}|{2}", icon, caption, msg);

AddToCartNotification.Value = value;

AddToCartNotification.Show();

}

protected void AddToCartNotification_CallbackUpdate(object sender, Telerik.Web.UI.RadNotificationEventArgs e)

{

RadNotification notification = sender as RadNotification;

if(notification == null)

return;

string[] vals = notification.Value.Split('|');

if (vals == null || vals.Length < 3)

return;

AddToCartNotification.TitleIcon = vals[0];

AddToCartNotification.Title = vals[1];

//AddToCartNotification.ContentIcon = vals[0];

AddToCartNotification.Text = vals[2];

}

I'm able to set the Text property but not able to set the Title and TitleIcon properties. Am I missing something or is this not possible?

Thanks -- Steve
