RadNotification notification = new RadNotification();

notification.LoadContentOn = Telerik.Web.UI.NotificationLoad.TimeInterval;

notification.CallbackUpdate +=_notification_CallbackUpdateOnTime;

protected void _notification_CallbackUpdateOnTime(object sender, RadNotificationEventArgs e)

{

if( <some condition>)

Dynamic resize of Gantt

Just curious if anyone has figured a way to dynamically resize the Gannt chart on the client side. I've tried resizing the entire div container but it looks like I'd have to do every container inside the main div. Is there an easier way?

Hide RadGrid Header Label When Inserting

Hello,

I am hoping that someone can help with a requirement I'm trying to accomplish. What I am trying to accomplish is when a new record is added I am wanting to hide the label and entry textbox based on the value of a dropdown. I have been able to successfully hide the textbox but I can't find a way to hide the label. From browsing the net and reading other forums I used the EditFormHeaderTextFormat property to set to empty and it does hide the label, but the issue now is setting the value in the code behind in the selectedindexchanged event back to a value. I have included sample code for what I have below. If anyone knows an alternate solution that would work please let me know.

Aspx

<telerik:GridTemplateColumn EditFormHeaderTextFormat="" DataField="CHIPReasonOther" DataType="System.String" FilterControlAltText="Filter Reason column" HeaderText="Define Other" SortExpression="ReasonOther" UniqueName="CHIPReasonOther">

<EditItemTemplate>

<telerik:RadTextBox ID="txtCHIPReasonOther" runat="server" Width="275px" MaxLength="50" Visible="false"></telerik:RadTextBox>

<asp:RequiredFieldValidator ID="rqdReasonOther" ControlToValidate="txtCHIPReasonOther" runat="server" ErrorMessage="Required" CssClass="validation" Enabled="false" Display="Dynamic"></asp:RequiredFieldValidator>

</EditItemTemplate>

<ItemTemplate>

<asp:Label ID="lblCHIPReasonOther" runat="server" Text='<%# Bind("CHIPReasonOther") %>' Enabled="True" Visible="true" />

</ItemTemplate>

</telerik:GridTemplateColumn>

Code behind

protected void rcbTempOOH_SelectedIndexChanged(object o, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

RadComboBox rcbSender = (RadComboBox)o;

GridEditFormItem item = rcbSender.NamingContainer as GridEditFormItem;

RadTextBox txtCHIPReasonOther = item.FindControl("txtCHIPReasonOther") as RadTextBox;

RequiredFieldValidator rqdReasonOther = item.FindControl("rqdReasonOther") as RequiredFieldValidator;

var selectedItem = e.Text;

selectedItem = Regex.Replace(selectedItem, @"\s+", "");

txtCHIPReasonOther.Text = string.Empty;

if (selectedItem == "Other")

{

txtCHIPReasonOther.Visible = true;

rqdReasonOther.Enabled = true;

}

else

{

txtCHIPReasonOther.Visible = false;

rqdReasonOther.Enabled = false;

}

RadScheduler rebind problem

Hello Telerik team,
I tried to found a solution how update RadScheduler after appoinment update but without success. For create/update appoinment I use iframe. On OnClientAppointmentInserting or OnClientAppointmentEditing I use jQuery plugin PrettyPhoto to open iframe.

function onAppointmentInserting(sender, eventArgs) {

eventArgs.set_cancel(true);

var targetSlot = eventArgs.get_targetSlot();

var categoryId = targetSlot.get_resource().get_key();

var day = eventArgs.get_startTime();

var date = '' + (1 + day.getMonth()) + '/' + day.getDate() + '/' + day.getFullYear();

jQuery.prettyPhoto.open('../PopUpAppoinmentInsert.aspx?categoryId=' + categoryId + '&start=' + date + '&end=' + date + '&iframe=true&width=700&height=500', 'Calendar item..');

jQuery('a.pp_close').css("display", "none");

function OnAppointmentEditing(sender, eventArgs) {

eventArgs.set_cancel(true);

var eventId = eventArgs.get_appointment().get_id()

jQuery.prettyPhoto.open('../PopUpAppoinmentInsert.aspx?eventId=' + eventId + '&iframe=true&width=700&height=500', 'Calendar item..');

jQuery('a.pp_close').css("display", "none"

);

}

After user click Save

protected void bSave_Click(object sender, EventArgs e)

{

try

{

CalendarCategory category = null;

CalendarEvent calendarEvent = null;

CalendarEventGovernor governor = new CalendarEventGovernor();

CalendarCategoryGovernor categoryGov = new CalendarCategoryGovernor();

//create entity

// ...

// then save

governor.Save(calendarEvent);

// after I write a javascript to close iframe and run my rebind method

ClientScriptsHelper.RegisterScript("window.parent.jQuery.prettyPhoto.close();window.parent.rebind(1);", true);

}

catch

{

}

How I rebind data from javascript

<telerik:RadAjaxManager ID="RadAjaxManager2" runat="server" OnAjaxRequest="RadAjaxManager2_AjaxRequest" DefaultLoadingPanelID="RadAjaxLoadingPanel2" >

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager2">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadScheduler1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

function rebind(schedule)

{

var ajax = $find('<%= RadAjaxManager2.ClientID%>');

ajax.ajaxRequest("ReBindRadScheduler" + schedule);

}

and server part

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

if (!IsPostBack)

{

cboCategory.DataSource = GetCategories();

cboCategory.DataBind();

cboCategory.Items[0].Selected = true;

cboCategory.Visible = false;

FillSchedule(RadScheduler1, 1);

FillSchedule(RadScheduler2, 2);

FillSchedule(RadScheduler3, 3);

FillSchedule(RadScheduler4, 4);

FillSchedule(RadScheduler5, 5);

}

protected void RadAjaxManager2_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

if (e.Argument == "ReBindRadScheduler1")

FillSchedule(RadScheduler1, 1);

//......

if (e.Argument == "ReBindRadScheduler5")

FillSchedule(RadScheduler5, 5);

}

private void FillSchedule(RadScheduler MainScheduler, int categoryId)

{

var defualtMinTime = TimeSpan.FromHours(6);

var defualtMaxTime = TimeSpan.FromHours(23);

MainScheduler.DayStartTime = defualtMinTime;

MainScheduler.WorkDayStartTime = MainScheduler.DayStartTime;

MainScheduler.DayEndTime = defualtMaxTime;

MainScheduler.WorkDayEndTime = MainScheduler.DayEndTime;

MainScheduler.Appointments.Clear();

MainScheduler.DataSource = null;

MainScheduler.DataBind();

var categories=GetCategoriesResources(categoryId);

MainScheduler.ResourceTypes.First().DataSource = categories;

//SchedulerToolTipManager.TargetControls.Clear();

CalendarEventGovernor governor = new CalendarEventGovernor();

MainScheduler.DataSource = governor.GetAllBy(categories.Select(x => x.Id).ToArray(), MainScheduler.SelectedDate, MainScheduler.SelectedDate.AddDays(MainScheduler.TimelineView.NumberOfSlots));

MainScheduler.DataBind();

MainScheduler.OnClientAppointmentInserting = "onAppointmentInserting";

MainScheduler.OnClientAppointmentEditing = "OnAppointmentEditing";

MainScheduler.OnClientAppointmentMoveEnd = "OnClientAppointmentMoveEnd";

MainScheduler.OnClientAppointmentMoveStart = "OnClientAppointmentMoveStart";

}

RadScheduler populated on Init but not rebind after insert/update. If I refresh page changes appear

Hello Again,

I am facing another issue. Again, there is a mix of controls. The problem is that c is null and an exception is thrown. I am using IE 10 to test by the way. Let me know if you require any additional information and I will post it.

Thanks,

Rad Grid - Group By - DropDownColumn text instead of value

GridGroupByExpression exp = GridGroupByExpression.Parse("group by " + name);

GridGroupByField field = new GridGroupByField();

field.FieldAlias = "Group";

field.FieldName = name;

exp.SelectFields.Add(field);

rg.MasterTableView.GroupByExpressions.Add(exp);

I have a rad grid that I am creating dynamicaly.
The grid has a drop down box control in it along with other fields such as text.

GridDropDownColumn gdc = new GridDropDownColumn();

gdc.Visible = visible;

gdc.DataField = uniqueName;

gdc.HeaderText = headerText;

gdc.ListTextField = "Value";

gdc.ListValueField = "ListValueId";

gdc.UniqueName = uniqueName;

gdc.DropDownControlType = GridDropDownColumnControlType.DropDownList;

When I group by the drop down column, I get it grouped by the value instead of the text.

Is there a way to specify which one?

I need value and text to be different so making them the same is not a solution.

Prevent wrapp

I am trying to prevent wrapping of too long columns to the second line.
I was able to do it by cutting size of the

Protected Sub AllGrids_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)

        Dim intMaxLength As Integer = 60

        Dim grd As RadGrid = CType(sender, RadGrid)

        If (TypeOf e.Item Is GridDataItem) Then

            Dim gridItem As GridDataItem = CType(e.Item, GridDataItem)

            gridItem("Description").ToolTip = gridItem("Description").Text

            If gridItem("Description").Text.Length > intMaxLength Then
                gridItem("Description").Text = gridItem("Description").Text.Substring(0, intMaxLength) + "..."
            End If

        End If

    End Sub

In addition i have to do some manipulation on export to export full size field.

There are gotta be a better way though, right?
