All Day Events in Timeline View

Hi,

Is there a way to display an 'all day' row in the timeline view, similar to week view. Our timeline view is showing a day per column and we like the use of the all day row to place notes relevant for the whole days, on the top. Do you have other suggestions for displaying multi-day notes?

Thanks,
Wen

Load on Demand - Missing value for parameter

In this project we have a rotator that should load items as needed, so we created a web service to do just that. In your example, you use a WCF web-service. After trying that unsuccessfully we switched over and tried creating an asmx web service. We are getting the following error:

RadRotator items request failed:
Exception = Invalid web service call, missing value for parameter: 'index'.

Any assistance in getting past this would be great!

Here is the code for the rotator:

<telerik:RadRotator ID="ItemRotator" runat="server" Width="100%" Height="500px" CssClass="horizontalRotator"

ScrollDuration="500" FrameDuration="1" ItemHeight="200" ItemWidth="230" RotatorType="ButtonsOver"

WrapFrames="false" >

<WebServiceSettings Path="~/Services/Assessment.asmx" Method="LoadAssessmentItemThumbnails"/>

</telerik:RadRotator>

And the web service:

using System;

using System.Collections.Generic;

using System.Web.Services;

using Telerik.Web.UI;

using Thinkgate.Base.Classes;

namespace Thinkgate.Services

{

/// <summary>

/// Summary description for Assessment1

/// </summary>

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

[System.ComponentModel.ToolboxItem(false)]

// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.

[System.Web.Script.Services.ScriptService]

public class Assessment1 : System.Web.Services.WebService

{

[WebMethod(true)]

[System.Web.Script.Services.ScriptMethod]

public RadRotatorItemData[] LoadAssessmentItemThumbnails(int index = 0, string argument = "")

{

List<RadRotatorItemData> result = new List<RadRotatorItemData>();

List<AssessmentItem> itemList = AssessmentItem.GetIncrementedAssessmentItemsByGradeSubjectCourse("01", "Mathematics", "Mathematics", index, index + 10);

foreach (AssessmentItem item in itemList)

{

var rotatorItemData = new RadRotatorItemData();

rotatorItemData.Html = @"<div style='position: relative; background-color: green'>"

+ @"<input style='position: absolute; top: 0px' type='checkbox'/>"

+ @"<img style='position: absolute; top: 0px; left: 30px;' "

+ @"src='/Thumbnails/thumb_item_" + item.ID + ".png' "

+ @"alt='Item Thumbnail' onerror='onImgError(this);' onLoad='setDefaultImage(this);' /></div>";

result.Add(rotatorItemData);

}

return result.ToArray();

}

If we need to switch back to an svc web service please help us to set this up in the web.config as that was also an issue.

In addition, can the html be loaded into rad docks on item data bound?

Thanks in advance,
Steven

RadGrid and LinqToSQL

I am using MS Visual Studio 2010 in a 3.5 environment.
I am using Microsoft Vista (32 bit)
The database is currently located on an SQL 2005 server.
I am using RadGrid & tools, version 2012.1.411.35
I am using both Chrome (18.0.1025.168) and Internet Explorer (8.0.7600.16385)
I am programming in VB.net

I'll preface this with the fact that I don't really know anything about LinqToSql. I am trying to follow instructions online, but most always assume the reader knows more than I do.

I have an SQL database of 215,000 records that I loaded in a RadGrid with an ASP SqlDataSource. This was slow to load, filter, sort, and go to the next or previous page.

I came across the article Grid / 300 000 Rows with LINQ and tried to implement this and eventually I did. The data loads and I can do everything I did in the original setup. It is still slow except for filtering which is pretty quick. Nothing works fast like the demo on the page I linked above.

Also, the code sets the TotalRowCount to 300000, so even if it's filtered to 10 items, there are still loads of pages to page through which is odd.

I also attempted to apply the solutions located here Grid / Custom Paging, but again, it assumes the reader knows more than I do. It also uses demo files and whatnot, so I've been unable to get it working for me.

Basically, I want to speed this up. I'd like to get the LinqToSQL working properly.

The HTML for my page is:

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

If Not Cache("MyData") Is Nothing AndAlso Not e.Result Is Nothing Then

Cache("MyData") = e.Result

End If

End Sub

Protected Sub LinqDataSource1_Selecting(sender As Object, e As System.Web.UI.WebControls.LinqDataSourceSelectEventArgs) Handles LinqDataSource1.Selecting

e.Arguments.TotalRowCount = 300000

If Not Cache("MyData") Is Nothing Then

e.Result = Cache("MyData")

End If

End Sub

Protected Sub RadAjaxManager1_AjaxSettingCreating(sender As Object, e As Telerik.Web.UI.AjaxSettingCreatingEventArgs) Handles RadAjaxManager1.AjaxSettingCreating

If Not e.Updated Is RadGrid1 Then

e.UpdatePanel.RenderMode = UpdatePanelRenderMode.Inline

End If

End Sub

End Class

Thank you for your assistance,

Rick

PS - Please have patience. You may need to step me through some of the stuff that may be simple to you. :)

OnRowDrop e.HtmlElement=="undefined" instead of "" (Empty)

Hi everybody,

Iam starting this thread cause I couldnt find any answer to my problem in Google or this forum or somewhere else.
description:
I have got 3 Grids on my Page and want to drag a Item from Grid A and drop it on Grid B:
Grid A: source of drag
Grid B: target of drop
Grid C: test target of drop

My Grid C is an empty Grid without any special settings. Grid A is my source where I have some contact items listed. Grid B is wrapped into a telerik:RadAjaxPanel.
If I drag an item from Grid A and drop it on Grid C the eventargs in the codebehind in OnRowDrop looks like this:

? e

{Telerik.Web.UI.GridDragDropEventArgs}

base {System.EventArgs}: {Telerik.Web.UI.GridDragDropEventArgs}

DestDataItem: {Telerik.Web.UI.GridDataItem}

DestinationGrid: {DotNetNuke.Web.UI.WebControls.DnnGrid}

DestinationTableView: {Telerik.Web.UI.GridTableView}

DraggedItems: Count = 1

DropPosition: Above

HtmlElement: ""

If I drag an item from Grid A and drop it on Grid B the eventargs looking like:

? e

{Telerik.Web.UI.GridDragDropEventArgs}

base {System.EventArgs}: {Telerik.Web.UI.GridDragDropEventArgs}

DestDataItem: null

DestinationGrid: null

DestinationTableView: null

DraggedItems: Count = 1

DropPosition: Above

HtmlElement: "undefined"

This is only caused by the telerik:RadAjaxPanel if I remove the ajaxpanel it will work like in the first drag drop.
I alrdy read documentations here on telerik.com and looked into demos but couldnt find any answer to my problem.
I thought something about using the OnDragging method on client side to determine if the destination is wrapped by a telerik:RadAjaxPanel and react on this. For example setting the eventarg properties and filling it with the correct data on client side. (But this is just a guess I couldnt get it working)

It would be awesome if someone could help me with this problem.

best regards, noone.

Shared Calendar Selected Date value in Updated event of RadGrid

Hi,

I am using a Rad Shared Calendar in edit item template of a Rad Grid. I have implemented the solution exactly like you have shown it in your demo, with the same textbox and javascript. It is showing the correct selected value, but in Updated event of RadGrid it is always giving the me old value of textbox. Can you tell me how to get the new selected value in code behind from the text box?
