Filtering Datetime column

I have a grid that has several Date Time columns. The value in these columns is dependent towards the time and not so much the date. When I go into the filter and enter a date and a time the filter does not accept this value and clears the field when I tab out or click somewhere else. However if I only enter a date and no time it will accept that filter. How do I get the filter to accept the time value as well?

Cancel zoom, retrieving start and end date from selection zoom

Hello,

I want to implement some functionnalities using chartview. Let me explain :
- i have a chartview with one horizontal axis as DateTimeContinousAxis and some vertical axis
- i want to implement the zoom, it's ok, following code that i'm using :

<telerik:RadCartesianChart x:Name="chartVariables" ... Zoom="{Binding Zoom, Mode=TwoWay}"

PanOffset="{Binding PanOffset, Mode=TwoWay}" >

<telerik:RadCartesianChart.Behaviors>

<telerik:ChartPanAndZoomBehavior ZoomMode="Both" PanMode="None" />

</telerik:RadCartesianChart.Behaviors>

</telerik:RadCartesianChart>

- Using a toggle button, on check, i want to make a selection like zoom on the chart, get start date and end date and cancel the zoom
but some problems occurs:
- The end date that i'm retrieving is wrong but the start date is ok

To do that i implemented the PanOffsetChanged event and i wrote the following code :

private void chartVariables_PanOffsetChanged(object sender, ChartPanOffsetChangedEventArgs e)

{

if ((bool)this.btnInvalidate.IsChecked)

{

DateTimeContinuousAxis axis = chartVariables.HorizontalAxis as DateTimeContinuousAxis;

DateTime startDate = axis.ActualVisibleRange.Minimum; // value is ok

DateTime endDate = axis.ActualVisibleRange.Maximum; // wrong

tbLog.Text = "From : " + startDate.ToString() + " - To : " + endDate.ToString();

chartVariables.Zoom = oldZoom; // cancel the zoom

}

Anybody can help me?
Thanks in advance
Regards

Styles Issue in Prism

Hi,

I have an application in which we are using the RadTabControl with prism framework, and also we are doing a switching of themes in our application. We are switching between 3 Telerik themes (Office 2013, Visual Studio 2013 and Windows 8).

I face the following issues:
The tab headers do not come correctly, if i try to set it with the RadTabControl ItemTemplate property, but my theme switching works fine.
The tab headers come correctly, if i try to set it with the RadTabItem HeaderTemplate property, but my theme switching thereafter doesn't work correctly.
Also, can you please explain the difference between the RadTabControl's ItemTemplate property and the RadTabItem's HeaderTemplate property. My tab header comes fine when set the RadTabItem HeaderTemplate property, but not with the RadTabControl ItemTemplate property. The tabs have a TabItemStyle in the resource dictionaries- using which we inserted a close button into each tab.

I am also attaching a sample image showing the theme issue I am facing.

Please guide me as to how I can do both, i.e., show the tab header as i require (An image, a text and a close button) and also work correctly when toggling between themes.

Thanks.

Keyboard focus multiple RadPanes

I have a RadPaneGroup that hosts multiple RadPanes, Each RadPane contains a User Control, Each UserControl is very simple just some text boxes, I am having problem with keeping the key board focus when user switches between RadPanes.

- After starting the application, there are 2+ radpanes
- Click on a text box in first rad pane
- Switch to the next Rad Pane
- go back to the first rad pane
- I would expect that the key board focus is on the last text box that i clicked
- The focus is no on any control on the first rad pane

Thanks

[Solved] Import Table from RadSpreadsheet

Is it possible to import a Table from RadSpreadsheet like MS Word form MS Excel?

Until now it seems to me, that I only can import it as Plaintext. So the backgroundcolor, etc. goes lost.

Thanks in advance.

expand event?

Hello, thank you for your last help. I still have a last question to my evaluation related to the gantt control.
Is there a possibility to get the tree-column expanded event in code behind? The goal is to load huge data on demand when
e.g. summary task is expanding on table side. For us this is a very important feature and basically neccessary.
Are there any plans or possibilitys to resolve this issue for our requirements?

Best Regards ... Robert

Select Items from selected row

I am using telerik:RadGridView along with telerik:RadContextMenu.ContextMenu to generate a right click menu inside my application. I need to be able to grab the servername and session id from the selected row in order to pass to the Disconnect and Logoff functions. However I ma having difficulty grabbing the data I need.

Here is the XAML for the component

<telerik:RadGridView x:Name="UserSessionGrid" IsReadOnly="True" FontWeight="Bold" AutoGeneratingColumn="UserSessionGrid_AutoGeneratingColumn" CanUserResizeColumns="False" CanUserDeleteRows="False" CanUserResizeRows="False" ClipboardCopyMode="All" Copied="UserSessionGrid_Copied" >

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu Opened="RadContextMenu_Opened" ItemClick="RadContextMenu_ItemClick">

<telerik:RadContextMenu.Items>

<telerik:RadMenuItem Header="Copy" />

<telerik:RadMenuItem Header="Disconnect" />

<telerik:RadMenuItem Header="Logoff" />

</telerik:RadContextMenu.Items>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

</telerik:RadGridView>

Here is the relevant code that handles the Right Click

/// <summary>

/// Handles the ItemClick event of the RadContextMenu control.

/// </summary>

/// <param name="sender">The source of the event.</param>

/// <param name="e">The <see cref="Telerik.Windows.RadRoutedEventArgs"/> instance containing the event data.</param>

private void RadContextMenu_ItemClick(object sender, Telerik.Windows.RadRoutedEventArgs e)

{

RadContextMenu menu = (RadContextMenu)sender;

RadMenuItem clickedItem = e.OriginalSource as RadMenuItem;

GridViewRow row = menu.GetClickedElement<GridViewRow>();

GridViewCell cell = menu.GetClickedElement<GridViewCell>();

GridViewRowItem rowitem = menu.GetClickedElement<GridViewRowItem>();

if (clickedItem != null && row != null)

{

string header = Convert.ToString(clickedItem.Header);

switch (header)

{

case "Copy":

Clipboard.SetText(cell.Value.ToString());

break;

case "Disconnect":

// Grab Server Name Column and Session ID Column Data

break;

case "Logoff":

// Grab Server Name Column and Session ID Column Data

break;

default:

break;

}

/// <summary>

/// Handles the Opened event of the RadContextMenu control.

/// </summary>

/// <param name="sender">The source of the event.</param>

/// <param name="e">The <see cref="RoutedEventArgs"/> instance containing the event data.</param>

private void RadContextMenu_Opened(object sender, RoutedEventArgs e)

{

RadContextMenu menu = (RadContextMenu)sender;

GridViewRow row = menu.GetClickedElement<GridViewRow>();

if (row != null)

{

row.IsSelected = row.IsCurrent = true;

GridViewCell cell = menu.GetClickedElement<GridViewCell>();

if (cell != null)

{

cell.IsCurrent = true;

}

else

{

menu.IsOpen = false;

}

Here is my session class

class Session

{

public String Server { get; set; }

public String Domain { get; set; }

public String User { get; set; }

public int sID { get; set; }

public ConnectionState State { get; set; }

public IPAddress IP { get; set; }

public String Workstation { get; set; }

public DateTime? Connect { get; set; }

public DateTime? Login { get; set; }

public TimeSpan Idle { get; set; }

/// <summary>

/// Initializes a new instance of the <see cref="Session"/> class.

/// </summary>

/// <param name="server">The server.</param>

/// <param name="domain">The domain.</param>

/// <param name="user">The user.</param>

/// <param name="session">The session.</param>

/// <param name="state">The state.</param>

/// <param name="ip">The ip.</param>

/// <param name="workstation">The workstation.</param>

/// <param name="connect">The connect.</param>

/// <param name="login">The login.</param>

/// <param name="idle">The idle.</param>

public Session (string server, string domain, string user, int session, ConnectionState state, IPAddress ip, string workstation, DateTime? connect, DateTime? login, TimeSpan idle)

{

this.Server = server.ToUpper();

this.Domain = domain.ToUpper();

this.User = user;

this.sID = session;

this.State = state;

this.IP = ip;

this.Workstation = workstation.ToUpper();

this.Connect = connect;

this.Login = login;

this.Idle = idle;

}

Which is populated by using the following code

/// <summary>

/// Handles the DoWork event of the worker control.

/// </summary>

/// <param name="sender">The source of the event.</param>

/// <param name="e">The <see cref="DoWorkEventArgs"/> instance containing the event data.</param>

private void worker_DoWork(object sender, DoWorkEventArgs e)

{

App.Current.Dispatcher.Invoke((Action)delegate

{

UserSessionGrid.IsBusy = true;

});

ITerminalServicesManager manager = new TerminalServicesManager();

foreach (var ServerName in ServerList)

{

using (ITerminalServer server = manager.GetRemoteServer(ServerName))

{

try

{

server.Open();

foreach (ITerminalServicesSession session in server.GetSessions())

{

items.Add(new

Session(server.ServerName, session.DomainName, session.UserName, session.SessionId, session.ConnectionState, session.ClientIPAddress, session.WindowStationName, session.ConnectTime,session.LoginTime, session.IdleTime));

//worker.ReportProgress(session.SessionId);

}

server.Close();

}

catch (Win32Exception) { }

catch (SystemException) { }

catch (Exception) { }

}
