DateTimeColumn Null Exception

Hi I urgantly need some help
I have a RadGrid with myltiple Fields of which 2 is DateTimeColumns
I use the NeedDataSource to get data from a DataTable in the Database.
I need the EndDate Column to be able to Take nulls and Display Nulls When Returned from Database.
I can Insert Send Null Values To the Database When Inserting. But When I Need to Get The Null Date Back From The Database
I keep getting the Error: Specified cast is not valid. regarding the DateTime of EndDate.

This is my Form Code:

<telerik:RadGrid ID="rgParameters" runat="server"

AutoGenerateDeleteColumn="True" AutoGenerateEditColumn="True"

AlternatingItemStyle-BackColor="white" GridLines="None"

GroupingEnabled="False" Width="100%" Height="500px"

AutoGenerateColumns="False"

ondeletecommand="rgParameters_DeleteCommand"

oninsertcommand="rgParameters_InsertCommand"

onneeddatasource="rgParameters_NeedDataSource"

onupdatecommand="rgParameters_UpdateCommand"

oniteminserted="rgParameters_ItemInserted">

<AlternatingItemStyle BackColor="White" />

<MasterTableView Caption="Parameters"

CommandItemDisplay="TopAndBottom"

DataKeyNames="ScheduleParaID,StartDate,EndDate,WeekScheduled,WEPHScheduled"

ShowFooter="true">

<Columns>

<telerik:GridBoundColumn AllowFiltering="False" AllowSorting="False"

DataField="ScheduleParaID" HeaderText="ScheduleParaID"

ReadOnly="true" UniqueName="ScheduleParaID" Visible="False">

</telerik:GridBoundColumn>

<telerik:GridDateTimeColumn AllowFiltering="False" DataField="StartDate"

HeaderText="Start Date" UniqueName="StartDate" DataFormatString="{0:dd/MM/yyyy}">

</telerik:GridDateTimeColumn>

<telerik:GridDateTimeColumn AllowFiltering="False" DataField="EndDate"

HeaderText="End Date" UniqueName="EndDate" DataFormatString="{0:dd/MM/yyyy}" Reorderable="True">

</telerik:GridDateTimeColumn>

<telerik:GridNumericColumn AllowFiltering="False" DataField="WeekScheduled"

HeaderText="Trains Scheduled (Week Days)" UniqueName="WeekScheduled" AllowRounding="False">

</telerik:GridNumericColumn>

<telerik:GridNumericColumn AllowFiltering="False" DataField="WEPHScheduled"

HeaderText="Train Scheduled (WE and Public Holidays)" UniqueName="WEPHScheduled" AllowRounding="False">

</telerik:GridNumericColumn>

</Columns>

<EditFormSettings EditFormType="AutoGenerated"></EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

This is my Code Behind part one.

protected void rgParameters_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

TrainOperationParameters tparam = new TrainOperationParameters();

rgParameters.DataSource = tparam.Select();

tparam = null;

}

This is my Code Behind For My DataEntity

[DataObjectMethod(DataObjectMethodType.Select, true)]

public List<TrainOperationParameters> Select()

{

List<TrainOperationParameters> list = new List<TrainOperationParameters>();

DataTable dt;

try

{

dt = DataMethods.ReturnMultipleRowResultSet("[IM].[GetTrainOpParameters]", String.Empty);

if (dt.Rows.Count > 0)

{

foreach (DataRow dr in dt.Rows)

{

TrainOperationParameters param = new TrainOperationParameters();

param.ScheduleParaID = Convert.ToInt32(dr["TrainOpParaID"]);

param.StartDate = (DateTime)dr["StartDate"];

param.EndDate = ((DateTime)dr["EndDate"]);

param.WeekScheduled = Convert.ToInt32(dr["WeekScheduled"]);

param.WEPHScheduled = Convert.ToInt32(dr["WEPHScheduled"]);

list.Add(param);

}

catch (Exception)

{

throw;

}

finally

{

dt = null;

}

return list;

}

Any Advice on why I keep Getting the Error and how I might be able to Fix it.

telerik:GridDateTimeColumn

Hello,

I have a little problem with RadGrid and 2 columns of type GridDateTimeColumn.

Extract data from the database server and bind it to the RadGrid.

There are two GridDateTimeColumn columns. I set both to have PickerType="DateTimePicker" as property. Also set EditMode="InPlace" for the RadGrid.
I put this RadGrid in aspx page which uses MasterPage. When the page loaded and I put the RadGrid into edit mode the columns look like ( before.png). When I press on the horisontal scroll in the RadGrid these two columns change there position. Please see the attached photo ( after.png). It looks like these two columns have absolute position? Any ideas how to fix that?

If I change RadGrid's property EdidMode to "PopUp" and after that change I press on RadGris's vertical scroll this problem does not exists. But I have many columns so this edit mode does not works for me.

Thanks in advance.

No Data from OData

I've got a WCF Data Service which is correctly publishing data (checked in the browser), yet when I hook it up to a RadTreeView or a RadMenu, nothing is rendered in the Browser...

My markup looks like this (generated by smart tags):

<telerik:RadODataDataSource ID="RadODataSource1" runat="server">

<Transport>

<Read Url="http://localhost:8989/ODService.svc/" DataType="XML" />

</Transport>

<Schema>

<telerik:DataModel ModelID="Thing" Set="Things">

<telerik:DataModelField FieldName="Id" />

<telerik:DataModelField FieldName="Name" />

<telerik:DataModelField FieldName="Value" />

</telerik:DataModel>

</Schema>

</telerik:RadODataDataSource>

<telerik:RadTreeView ID="RadTreeView1" Runat="server" DataFieldID="Id" DataModelID="Thing" ODataDataSourceID="RadODataSource1"></telerik:RadTreeView>

The output in the browser when directed to http://localhost:8989/ODService.svc/Things looks like this:

      </m:properties>
    </content>
  </entry>
</feed>

and finally, the source from the rendered web page where the control should be, looks like this:

<div id="RadTreeView1" class="RadTreeView RadTreeView_Clear">

<input id="RadTreeView1_ClientState" name="RadTreeView1_ClientState" type="hidden" autocomplete="off" value="{"expandedNodes":[],"collapsedNodes":[],"logEntries":[],"selectedNodes":[],"checkedNodes":[],"scrollPosition":0}">

</div>

Is there something I'm doing wrong?

I can post up the code from the data classes or the context, but the fact that the service is outputting into the browser (as above) without problems, allowing me to correctly query it, would suggest that the problem isn't in the service itself.

RadDatepicker Disabling dates and changing disabled dates on postback

I need to be able to have a calendar which only allows the user to select a saturday if a 7 nights is chosen from a combo box on a form and to allow the user to just select a monday if an 4 nights is chosen from the combo box.

I am currently using the RadDatepicker and have set it up to add the disabled dates for the year to the special days. So if a 7 is selected the dt variable will be every day except a saturday.

RadCalendarDay holiday = new RadCalendarDay();

holiday.Date = dt;

holiday.IsSelectable = false;

holiday.IsDisabled = true;

CalendarPopup1.Calendar.SpecialDays.Add(holiday);

I don't seem to be able to get this to work. I am also trying to reset the calendar whenever the combo box value changes. But can't get this to work either.

public void ResetCalendar()

{

CalendarPopup1.Clear();

CalendarPopup1.Calendar.SpecialDays.Clear();

}

RADComboBox in Grid

Hi Forum,
I have a RADGrid with a RADComboBox column with EnableLoadOnDemand=true and ItemsRequest event defined.

<telerik:RadComboBox ID="cboLocalita"

EnableVirtualScrolling="true"

OnItemsRequested="cboLocalita_ItemsRequested"

ShowMoreResultsBox="true"

EnableLoadOnDemand="true"

DataTextField ="descrizione"

DataValueField ="idlocalita"

runat="server">

</telerik:RadComboBox>

Protected Sub cboLocalita_ItemsRequested(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs)

Dim context As New JLogTabelleDataContext

Dim allLocalita = From localita In context.localita _

Order By localita.descrizione _

Select localita

If Not [String].IsNullOrEmpty(e.Text) Then

allLocalita = From localita In context.localita _

Where localita.descrizione.StartsWith(e.Text) _

Order By localita.descrizione _

Select localita

End If

Dim Lstlocalita = allLocalita.Skip(e.NumberOfItems).Take(10)

CType(o, RadComboBox).DataSource = Lstlocalita

CType(o, RadComboBox).DataBind()

Dim endOffset As Integer = e.NumberOfItems + Lstlocalita.Count()

Dim totalCount As Integer = allLocalita.Count()

If endOffset = totalCount Then

e.EndOfItems = True

End If

e.Message = [String].Format("Rec <b>1</b>-<b>{0}</b> Tot <b>{1}</b>", endOffset, totalCount)

End Sub

The automatic CRUD operation enabled on the Grid doesn't work, so the value of RADComboBox never change after update of then EditForm and is setted to NULL when I perform a created operation.

If I bind the Combobox to a Datasource object by the property DataSourceID and I disable EnableLoadOnDemand without implement OnItemsRequest event , CRUD works fine. I have a lot of records to show in ComboBox therefore Loading data on demand is very important.
Thanks to all for any response.
Gaetano
