When I move tasks around it ends up with an error. Especially when I move a task to an earlier point in time.

The problem is: Telerik (let's call it like that) updates automaticly, but a NULL-value is assigned to a random record in the Expanded column.

And the Gantt doesn't allow this value because its a bit so. 1 or 0

Help please.

Drop Down List Not Selecting

Here's the situation:

I am testing a form using Telerik Test Studio.

There are 3 drop downs (State, City, Building) and what you choose on the previous box decides what is in the next box. Before you choose what is in the drop down box number one, two and three are empty (no choices). When you choose a State, it gives you options for cities, then once you choose a city, the building drop down gets populated with options.

The problem is, when I am testing this with the drop downs, it chooses the state correctly, but it, for some reason, doesn't register that there is a state chosen, so the city drop down does not get populated. I slowed the process down while the test is running to try and see if it was something simple, but I saw myself that it DOES choose a state, so I tried to manually choose the city but there was nothing to populate the drop down options. But, if I choose the state myself, then the cities populate.

Thank you for your help.

Scheduler as SharePoint web part - validation

Hi, I have created a custom SharePoint 2010 web part using a scheduler with some custom attributes. Everything is working fine except for validation of the custom attributes on the advanced edit/insert form. There are two text boxes which should not be empty and save should not allow the advanced form to be saved back to the SP list.

I have the following code in the FormCreated event:

RadScheduler scheduler = (RadScheduler)sender;

CustomValidator validatorForAttributePhone = new CustomValidator();

validatorForAttributePhone.ValidationGroup = scheduler.ValidationGroup;

validatorForAttributePhone.ControlToValidate = "AttrPhone";

validatorForAttributePhone.ErrorMessage = "Cannot be blank!";

validatorForAttributePhone.ClientValidationFunction = "validationFunctionPhone";

(e.Container.FindControl("AttrPhone") as RadTextBox).Parent.Controls.Add(validatorForAttributePhone);

And the jsavascript function is

function validationFunctionPhone(source, arguments)

{

if (arguments.Value.length != 0)

{ arguments.IsValid = true; }

else {arguments.IsValid = false; }

}

All the validation seems to be created OK but this never fires when the 'Save' button is clicked on the advanced edit/insert form which means that the appointment can be saved when there is no text in the phone field on the form.

What am I missing?

Thanks,

Jonathan

Updating from RadDataForm using ObjectDataSource

I've been trying to update the data in my RadDataForm for a long time now but without success.

I am using an object called UtilisateurDetailViewModel (code below) and a class name UtilisateurDetailDataObject that takes care of doing the DB calls (CRUD) through a standard BLL-DAL etc.

I bind my data to my form using a double click that calls the select method on ym ObjectDataSource using parameters.

The problem I am facing is that watever I do, clicking my button with the CommandName="Update" in the EditItemTemplate doesn't do anything. I have tried tons of things to make it work but nothing.

Here is all my code, hoping it's only a little mistake or an option that's missing. I know it is a big chunk of code, but the UtilisateurDetailViewModel and RadDataForm have a lot of repitition that doesn't need reading since it's just several radtextboxed for the values.

1. My UtilisateurDetailViewModel object

01.namespace CCQ.GestionSEL.Intranet.ZJWEB013.ViewModel

02.{

03. public class UtilisateurDetailViewModel

04. {

05. private Utilisateur _utilisateur;

06. private Compte _compte;

09. {

10. if (us_net == null)

11. throw new ArgumentNullException("us_net");

12.

13. if (ut_net == null)

14. throw new ArgumentNullException("ut_net");

15.

16. _utilisateur = us_net;

17. _compte = ut_net;

18. }

19. public string Type

20. {

21. get { return _utilisateur.TyUtilNet.Trim(); }

22. set { _utilisateur.TyUtilNet = value; }

23. }

24. public string NumeroUtilisateur

25. {

26. get { return _utilisateur.IdentUtilNet.Trim() + "-" + _utilisateur.NoUsagerNet; }

27. set { _utilisateur.IdentUtilNet = value; }

28. }

29. public string NomPrenom

30. {

31. set { _utilisateur.NomPrenom = value; }

32. get { return _utilisateur.NomPrenom.Trim(); }

61. }

62. public string Statut

63. {

64. get { if (_compte.statut == 1) { return "Actif"; } else { return "Inactif"; } }

65. set { if (value == "Actif") { _compte.statut = 1; } else { _compte.statut = 0; }; }

66. }

67. public DateTime? DateStatut

68. {

69. get { if (_compte.statut == 1) { return _compte.DteCreer; } else { return _compte.DteInactif; } }

70. }

Raise Master Table View Add New Record Button in code behind

I'm hoping that someone can help me. I have a radgrid with a Add New Sales Opportunity button on the command bar at the top of the MasterTableView. When clicked the ItemCreated event is fired. I have a JavaScript alert that asks if the user wants to create another record after they have saved their first. I am using a HiddenField on the user control to send the response back to the server side. What I need to do is raise the ItemCreated event in the code behind to open a new add form if the user options to create a new record.

Here's a snippet of how my grid is created in the user control:

<telerik:RadGrid runat="server" ID="grdSalesOpportunity" CssClass="grdSalesOpportunityClass" AllowPaging="True" AllowCustomPaging="true"
AutoGenerateColumns="false" EnableLinqExpressions="false"
AllowSorting="true" GridLines="Both" OnNeedDataSource="grdSalesOpportunity_NeedDataSource" CommandItemStyle-CssClass="swrap"
OnItemDataBound="grdSalesOpportunity_ItemDataBound"
NonExportingColumns="EditCommandColumn,DeleteColumn,AddNotes" ShowAllExportButtons="false"
OnSortCommand="grdSalesOpportunity_SortCommand" OnPageSizeChanged="grdSalesOpportunity_PageSizeChanged"
OnUpdateCommand="grdSalesOpportunity_UpdateCommand" OnInsertCommand="grdSalesOpportunity_InsertCommand"
OnItemCommand="grdSalesOpportunity_ItemCommand" OnItemCreated="grdSalesOpportunity_ItemCreated" ShowExtraButtons="true">
<ClientSettings Scrolling-AllowScroll="true" Scrolling-UseStaticHeaders="true"></ClientSettings>
<GroupingSettings CaseSensitive="false" />
<ExportSettings ExportOnlyData="True" IgnorePaging="True" OpenInNewWindow="True"
Pdf-PageWidth="350mm" Pdf-PageHeight="210mm" Pdf-PageLeftMargin="20mm" Pdf-PageRightMargin="20mm">
</ExportSettings>

<MasterTableView CommandItemDisplay="Top" DataKeyNames="SOID" AllowFilteringByColumn="true"
ClientDataKeyNames="SOID">
<CommandItemSettings ShowAddNewRecordButton="true" AddNewRecordText="Add New Sales Opportunity"
ShowExportToCsvButton="true" ShowExportToExcelButton="true" ShowExportToPdfButton="true"
ShowExportToWordButton="false" />

Javascript: Unterminated String Constant

Hello,

I'm trying to get a working RadHtmlChart. But as soon as i'm using a LinQ-DataSource, i'm getting an Javascript-Exception "0x800a03f7: Unterminated String Constant" and the Chart is empty

Here's the Code of the .aspx:

<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="800px" Height="500px">

<PlotArea>

<Series>

<telerik:ColumnSeries DataFieldY="PriceVk">

</telerik:ColumnSeries>

</Series>

<XAxis DataLabelsField="Name"></XAxis>

</PlotArea>

</telerik:RadHtmlChart>

And this is the Code Behind:

protected void Page_Load(object sender, EventArgs e)

{

var context = new StuffrulerDataContext(this.Connection);

var data = context.StuffItems.Where(i => i.PriceVk > 0).Take(5).ToList();

this.RadHtmlChart1.DataSource = data;

// this.RadHtmlChart1.DataSource = GetData();

this.RadHtmlChart1.DataBind();

}

protected DataTable GetData()

{

DataTable tbl = new DataTable();

tbl.Columns.Add(new DataColumn("PriceVk", typeof(decimal)));

tbl.Columns.Add(new DataColumn("Name", typeof(string)));

tbl.Rows.Add(new object[] { 100, "First" });

tbl.Rows.Add(new object[] { 200, "Second" });

return tbl;

}

When I'm using GetData() as Source, it works fine.

RadGrid PageSize not visible

Hello,
I'm using Telerik RadGrid to present some objects to user. When the grid is filled thru NeedDataSource event, everything works fine. But I'm experimenting with asynchronous data loading and binding data to grid thru RadGrid.Datasource seems better for this.
My problem is that when I bind data this way - setting RadGrid.Datasource and calling RadGrid.DataBind(), than the DropDown list for choosing PageSize stops showing the selected pagesize. The dropdown list alone works fine, I can change to different number of items per page, but no matter what i do, the number is not visible.
Sorting and filtering of the data is done in WCF service, so I have set AllowCustomPaging to true and I set the VirtualItemCount just after setting the DataSource property (just before calling DataBind()).
The grid then looks like this:
