Questions on UI for WinForms Forum

Hi,
I'm trying to implement F11 feature - full screen in my application.

It works like a charm for standard .NET Form, but for RadForm I have some inaccuracy.
Win7 x64 - on the top of the screen I see part of title bar which should be normally hidden by calling "targetForm.FormBorderStyle = FormBorderStyle.None;".
WinXP - on the top I still can see like 2px space from title bar, but more important is that it doesn't cover Windows taskbar in the bottom of the screen.

The Code is simple:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using Telerik.WinControls;

using Telerik.WinControls.UI;

namespace RadControlsWinFormsApp1

{

public partial class RadForm1 : RadForm

{

public FormState fs = new FormState();

public RadForm1()

{

InitializeComponent();

}

private void radButton1_Click(object sender, EventArgs e)

{

fs.Maximize(this);

}

private void radButton2_Click(object sender, EventArgs e)

{

fs.Restore(this);

}

/// <summary>

/// Selected Win AI Function Calls

/// </summary>

public class WinApi

{

[System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint = "GetSystemMetrics")]

public static extern int GetSystemMetrics(int which);

[System.Runtime.InteropServices.DllImport("user32.dll")]

public static extern void

SetWindowPos(IntPtr hwnd, IntPtr hwndInsertAfter,

int X, int Y, int width, int height, uint flags);

public static void SetWinFullScreen(IntPtr hwnd)

{

SetWindowPos(hwnd, IntPtr.Zero, 0, 0, GetSystemMetrics(0), GetSystemMetrics(1), 64);

}

/// <summary>

/// Class used to preserve / restore state of the form

/// </summary>

public class FormState

{

private FormWindowState winState;

private FormBorderStyle brdStyle;

private bool topMost;

private Rectangle bounds;

public bool IsMaximized = false;

public void Maximize(RadForm targetForm)

{

if (!IsMaximized)

{

IsMaximized = true;

Save(targetForm);

targetForm.WindowState = FormWindowState.Maximized;

targetForm.FormBorderStyle = FormBorderStyle.None;

targetForm.TopMost = true;

WinApi.SetWinFullScreen(targetForm.Handle);

}

public void Save(RadForm targetForm)

{

winState = targetForm.WindowState;

brdStyle = targetForm.FormBorderStyle;

topMost = targetForm.TopMost;

bounds = targetForm.Bounds;

}

public void Restore(RadForm targetForm)

{

targetForm.WindowState = winState;

targetForm.FormBorderStyle = brdStyle;

targetForm.TopMost = topMost;

targetForm.Bounds = bounds;

IsMaximized = false;

}

When you replace RadForm by Form everything is all right on both OS :-(

Any idea, any help?
Thanks Zbyněk

Help filtering rows

Hi,

I would like to filter my Radgridview and then iterate thru filtered rows. Can't be more simple... I use Winform Q3-2010

I have no problem to apply the filter. The RadGridView display only filtered rows. It is OK
But when I want to iterate in them, I read all the rows !!!

Here my code

Dim serveursource As String = "SRV-13-1;SRV-59-2"

Dim f As Integer

Dim words As String() = serveursource.Split(New Char() {";"c})

Dim strRowFilter As String

Dim filter As New FilterDescriptor()

filter.PropertyName = "Dest_Serveur"

filter.[Operator] = FilterOperator.IsEqualTo

filter.IsFilterEditor = True

RadGridView1.EnableFiltering = True

' Use For Each loop over words and display them

Dim word As String

For Each word In words

If word <> "" Then

filter.Value = word

Me.RadGridView1.FilterDescriptors.Add(filter)

f = 0

For Each rowInfo As GridViewRowInfo In RadGridView1.Rows

f += 1

Next

MsgBox(word & "Nb of rows:" & Me.RadGridView1.Rows.Count.ToString & ">>" & f.ToString)

End If

Next

What is wrong ?

Thanks

Hide titlebar and themes

Hello,
I'm trying to create a dialog form without title bar and use theme ("Windows8"). Shaped form for some reason uses another window background color, and applying theme doesn't change it. I tried to derive my form from RadForm and hide TitleBar with:

this.FormElement.TitleBar.Visibility = ElementVisibility.Collapsed;

Title bar is hidden. But when I apply "Windows8" theme to my application, my dialog has different border, where TitleBar should be. Also bottom border becomes 1px height, and when TitleBar is visible it is same as left and right borders.

How to accomplish desired look from the attached file?

Thank you.

TitleBar

SelectedRows is nothing

Hello,

We are using Rad Controls Professional Q2 2013. We have a radgridview on a radform that is returning the incorrect selectedrows information.

When the user selects a single row and clicks 'OK', the radgridview.selectedrows property returns a value of nothing. When the user selects multiple rows and clicks 'OK', the selectedrows property returns all selected rows except the the last selected row.

The selectionMode is set to FullRowSelect, and multiSelect is set to True.

When we changed the selectionMode to CellSelect and interrogated the radgridview.selectedcells property, the results were correct. This workaround, however, is not suitable for other radgridviews in our project.

Please advise if there is a fix for this problem.

Many thanks,
Jane

Loading Data Animation

Hello,

is there a simple way to show a "Loading Data" animation when asynchroniously fetching data?
In our application we create a RadTabPage with detailed information about a previously double clicked GridViewItem. This RadTabPage contains an empty RadGridView bound to a properly typed DataBindingsource. Until the data was successfully fetched from our database -- which can be time consuming -- the end user only sees this empty grid.

To communicate to the user that some data will appear, it would be great to overlay the grid with a spinner animation or some textual hint.

We would prefer a generic approach which only affects the GridView itself so that it can be wrapped into an extension method or extended class.

Kind regards,
Andreas Haeusler
