Cant get templatecolumn to show the text of the selected item of a radcombobox in an edititemtemplate

I cant get the item template to reflect the text of the selected item in the radcombobox that is in the edititemtemplate of my programmatically created gridtemplatecolumn

Code for creating the template column:

01.Dim tempDB As New SqlDataSource

02.Dim templateColumnName As String = col.Caption

03.Dim templateColumn As New GridTemplateColumn()

04.

05.templateColumn.DataField = col.Caption

06.templateColumn.ItemTemplate = New LCDisp(templateColumnName, ddQuery, DiConnectionString)

07.templateColumn.EditItemTemplate = New DDEdit(templateColumnName, ddQuery, DiConnectionString)

08.templateColumn.HeaderText = templateColumnName

09.

10.templateColumn.UniqueName = col.Caption

11.

12.grdReport.Columns.Add(templateColumn)

Code for LCDisp template:

01.Private Class LCDisp

02. Implements ITemplate

03. Protected lblCont As Label

04. Private colname As String

05. Private DSQuery As String

06. Private DiConnectionString As String

07.

08. Public Sub New(ByVal cName As String, ByVal query As String, ByVal connString As String)

09. colname = cName

10. DSQuery = query

11. DiConnectionString = connString

12. End Sub

13.

14. Public Sub InstantiateIn(container As UI.Control) Implements ITemplate.InstantiateIn

15. lblCont = New Label

16. lblCont.ID = "lControl" + colname

17. AddHandler lblCont.DataBinding, AddressOf litCont_DataBinding

18. container.Controls.Add(lblCont)

19. End Sub

20.

21. Sub litCont_DataBinding(ByVal sender As Object, ByVal e As EventArgs)

22. Dim l As Label = DirectCast(sender, Label)

23. Dim container As GridDataItem = DirectCast(l.NamingContainer, GridDataItem)

24. l.Text = (DirectCast(container.DataItem, DataRowView))(colname).ToString()

25. End Sub

26.End Class

Code for DDEdit:

01.Private Class DDEdit

02. Implements ITemplate

03. Protected DropDown As RadComboBox

04. Private colname As String

05. Private DSQuery As String

06. Private DiConnectionString As String

07. Private MyContainerDataItem As GridDataItem

08.

09. Public Sub New(ByVal cName As String, ByVal query As String, ByVal connString As String)

10. colname = cName

11. DSQuery = query

12. DiConnectionString = connString

13. End Sub

14.

15. Public Sub InstantiateIn(container As UI.Control) Implements ITemplate.InstantiateIn

16. DropDown = New RadComboBox

17.

18. Dim dv2 As New DataView

19. Dim oQuery As New cWjCoQuery

20.

21. oQuery.Load(DSQuery, ConfigurationManager.ConnectionStrings(DiConnectionString).ConnectionString)

22.

23. Dim tempDB As New SqlDataSource

24. tempDB.ID = colname + "DB"

25.

26. tempDB.SelectCommand = oQuery.SQLQuery

27. tempDB.ConnectionString = ConfigurationManager.ConnectionStrings(DiConnectionString).ConnectionString

28.

29. dv2 = tempDB.Select(DataSourceSelectArguments.Empty)

30. DropDown.DataSource = tempDB

31. If dv2.Table.Columns.Count > 1 Then

32. DropDown.DataTextField = dv2.Table.Columns.Item(0).Caption

33. DropDown.DataValueField = dv2.Table.Columns.Item(1).Caption

34. Else

35. DropDown.DataTextField = dv2.Table.Columns.Item(0).Caption

36. DropDown.DataValueField = dv2.Table.Columns.Item(0).Caption

37. End If

38.

39. DropDown.DataBind()

40.

41. MyContainerDataItem = TryCast(container.Parent, GridDataItem)

42. If MyContainerDataItem Is Nothing Then

43. MyContainerDataItem = TryCast(container.Parent.Parent, GridDataItem)

44. End If

45. If MyContainerDataItem IsNot Nothing Then

46. Dim tmpSelVal = MyContainerDataItem.GetDataKeyValue(colname).ToString

47. If Trim(tmpSelVal) <> "" Then

48. DropDown.SelectedIndex = DropDown.FindItemIndexByValue(CInt(tmpSelVal))

49. End If

50. End If

51.

52. container.Controls.Add(DropDown)

53. End Sub

54.End Class

Updating RadDiagram Data Sources

If RadClientDataSource is used for both the symbol and connection bound data sources, will the data sources, if they are to a SQL Server database, be updated when changes are made on the diagram; e.g. symbol title changed, new symbol or connection added, etc.?

If not, is there another approach or a relatively easy workaround to do this?

Thanks,

Donald

Showing image preview or thumbnail

Is there any way to show a preview or thumbnail of an image uploaded through CloudUpload?

My issue is that I'm letting users upload files to S3, but until a postback has occurred, I can't set them to be publicly viewable by any sort of thumbnail/preview by the user.

First item in a RadComboBox is always consider as selected and include in an insert

Hi to all!

I have an issue with a RadComboBox during an insert.

Context:

I've made an ASP.Net app for my company to visualize dependencies between our apps by using a RadGrid for raw data and D3.JS for graphic visualization. The logic is easy: FromApp (id) is link to ToApp (id) and you have a comment field too. To do a new insertion I use the "Add new record" button from the grid, in the EditTemplate I've put one FromAppRadComboBox where you can select one app, a ToAppRadComboBox with checkboxes where you can select all the apps link to the one selected befor and a Textbox for comments. For having a record per link, I've made a CustomInsertion function called during the OnInsertCommand of the grid.

Problem:

Regardless the amount of app I check in the ToAppRCB, it will always inserts the first item in addition to the others. I manage to fix this by using a default item, but once the insertion is done, when the app want to refresh then display the grid, it breaks, because of a convertion problem (maybe because of Entity Framework).

RadScheduler uses wrong date/time for ends of days

Having done a lot of work with RadScheduler over the last couple of weeks, I have discovered that it has a serious bug in how it determines the end of day.

Conventionally, a day starts at 00:00:00 and runs through to 23:59:59. Adding one more second moves to the start of the next day.

If you are looking at the week view and you set SelectedDate to 26Dec2016 00:00:00 (I use this notation here to avoid confusion, it is of course, a DateTime value), VisibleRangeStart is correctly set to 26Dec2016 00:00:00. VisibleRangeEnd is set to 2Jan2017 00:00:00. This is wrong! VisibleRangeEnd should be 1Jan2017 23:59:59 ie the week starting 26Dec runs from 26Dec to 1Jan, NOT 2Jan !

Unfortunately, it appears that RadScheduler has been entirely coded on the principal that the day runs from 00:00:00 to 00:00:00.values which is fundamentally wrong. This causes all kinds of problems and errors proliferating when trying to do anything with the scheduler because you end up having to code to correct for the error. Drag/Drop is similarly affected.

I should clarify that visually, the scheduler appears fine, but it transacts in the background with wrong data!

Does Telerik have any plans to correct this error ?

Tootipifying a client-side bound grid

I have often tootipified server-side bound grids. But now I would like to do so with a client-side bound grid. Is this possible?

When done server-side, I alter the tootip manager's targetcontrols collection in the grid's ItemDatabound event. Client-side I have access to the RowDataBound event which appears to be analogous, but I'm not sure how I would modify the tooltip manager's targetcontrols collection through client-side code.

RadAutoCompleteBox works on localhost but not when published.

I have a project with RadAutoCompleteBox and every thing works fine on my localhost, but when I upload it the page doesn't crash but the drop down doesn't appear at all but yet it works fine on my computer.

I have the RadAutoCompleteBox binded to a web service.

When I go to the web service page online I get the following error.

Cannot serialize member Telerik.Web.UI.AutoCompleteBoxData.Context of type System.Collections.Generic.Dictionary`2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], because it implements IDictionary.

Here is my code in the web service.

using ClassLibrary;

public class StaffWebService : System.Web.Services.WebService

string AcademicYear { get; set; }

[WebMethod(EnableSession = true)]

public AutoCompleteBoxData GetStaffNames(object context)

{

//Orignal code

//QueryData = context["Text"].ToString();

//var AcademicYear = Session["AcademicYear"];

//Testing code

string QueryData = ((IDictionary<string, object>)context)["Text"].ToString();

var AcademicYear = Session["AcademicYear"];

using (SqlConnection cn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["Connect"].ConnectionString))

{

cn.Open();

using (SqlCommand cm = cn.CreateCommand())

{

cm.CommandText = "sql stuff";

cm.Parameters.AddWithValue("@QueryData", QueryData);

cm.Parameters.AddWithValue("@AcademicPeriod", AcademicYear);

using (SqlDataAdapter objAdpt = new SqlDataAdapter())

{

objAdpt.SelectCommand = cm;

using (DataTable dt = new DataTable())

{

objAdpt.Fill(dt);

dt.DefaultView.Sort = "Name";

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

AutoCompleteBoxData dropDownData = new AutoCompleteBoxData();

result = new List<AutoCompleteBoxItemData>();

for (int i = 0; i < dt.Rows.Count; i++)

{

AutoCompleteBoxItemData itemData = new AutoCompleteBoxItemData();

itemData.Text = dt.Rows[i]["Name"].ToString();

itemData.Value = dt.Rows[i]["WINDOWS_USER_ID"].ToString();

result.Add(itemData);

}

dropDownData.Items = result.ToArray();

return dropDownData;

}

}//end of class

}//end of namespace

RadButton SingleClickText aligns dots left instead of right

Hi!

I encountered a weird phenomenon when using the SingleClick feature of the RadButton

<div class="footer" dir="rtl">

<telerik:RadButton RenderMode="Lightweight" runat="server" ID="buttonSave" Text="Speichern" SingleClick="true" SingleClickText="Speichere .." CausesValidation="False" OnClick="buttonSaveClicked" />

<telerik:RadButton RenderMode="Lightweight" runat="server" ID="buttonCancel" Text="Abbrechen" SingleClick="true" SingleClickText="Abbrechen .." CausesValidation="False" OnClick="buttonCancelClicked" />

</div>

When I click one of the buttons the displayed text is changing for the time of the PostBack, but the text shown is: ".. Speichere" and ".. Abbrechen" instead of the dots being after the string. When I set the SingleClickText to have letters after the dots it's shown correctly. The amount of dots don't change anything, neither do spaces between the dots and the normal text or after the dots.

In addition to that JS-Console says "no element found" when the button is clicked.

Is that a bug or am I missing something important?

Thanks already

Greetings Felix

How to load a RadScheduler in 24-Hours Mode

I would like my RadScheduler to appear in the 24 hours mode (that can be achieved with aTelerik.Web.UI.SchedulerNavigationCommand.SwitchFullTime command) -- But I don't want to do this as a result of any navigation, I just want to set it either in the ASPX declaration or on the server-side during initialization.

How do I do this?
