Show only the current row

In this application we are running around the warehouse and picking items for an order. The user gets to select any row in the gridview of items either by clicking that row or entering a search field and the program will find a row from that..

What I want to do is this:

1. When a row is selected, show only that row and show a panel where the user takes an action.

2. When the user completes the action for that row, restore the gridview to showing all of the rows and make that panel disappear.

How I think of this is:

A split container with two panels (and 0 for the splitter width). One panel contains the gridview. The other panel contains the controls for the user to execute the action for the selected gridview row.
When a row is selected, that panel and gridview will decrease their size to contain only the header row and the selected row. The other panel will expand into the vacated space in the split container. Reverse this when the action for that row is completed. (That other panel won't be visible.)
When the row is selected, no scrolling, no touching, nothing. It's there to show you what you have selected to work on. That's all.

I'm doing fine with collapsing the panels in the split container. I'd like help with

Either setting the current row as the first visible row or making the current row the only visible row (other suggestions are welcome).
Hiding the scroll bar and other things to keep the user out of the gridview when a row has been selected.
Calculating the height to set the gridview so that it is tall enough to show the header and one row (I think I've been there before).

Thank you.

CommandBarDropDownButton items show up in a wrong position

Hi Telerik Team,

i begin to developing a telerik UI by using c#. i added a CommandBarDropDownButton for language selection (English & Arabic). When i set currentculture as arabic and RightToLeft to Yes, CommandBarDropDownButton items, are onthe right side of screen, show up shifted position, in a wrong position. i attached the screenshots for clarifying problem.

Here is my code:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Globalization;

using System.Threading;

using System.Windows.Forms;

using Telerik.WinControls;

using Telerik.WinControls.UI;

namespace TelerikWinFormsApp2

{

public partial class Form1 : RadForm

{

private static RightToLeft right2Left = RightToLeft.No;

private readonly object _locker = new object();

public static CultureInfo CurrentCulture { get; set; }

private RightToLeft Right2Left

{

get { return right2Left; }

set {

if (!(right2Left == value))

{

lock(_locker){

right2Left = value;

CultureChangeFunc();

}

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

InitializeToolbar();

}

private void InitializeToolbar()

{

bseLayout.Grip.Visibility = ElementVisibility.Collapsed;

bseActions1.Grip.Visibility = ElementVisibility.Collapsed;

bseLanguage.Grip.Visibility = ElementVisibility.Collapsed;

bseLanguage.DesiredLocation = new PointF(10000, 0);

this.commandBarDropDownButton2.Image = Image.FromFile("icons\\32x32\\icon_list.png");

this.commandBarDropDownButton3.Image = Image.FromFile("icons\\32x32\\icon_settings.png");

this.commandBarDropDownButton4.Image = Image.FromFile("icons\\32x32\\icon_lang.png");

this.commandBarButton7.Image = Image.FromFile("icons\\32x32\\icon_info.png");

this.commandBarButton4.Image = Image.FromFile("icons\\32x32\\icon_help.png");

}

private void rmiLanguage_Click(object sender, EventArgs e)

{

var selectedItem = (RadMenuItem)sender;

if (selectedItem.Tag == null)

return;

try

{

if (selectedItem.Tag.Equals("rmiEnglish"))

{

CurrentCulture = new CultureInfo("en-US");

Right2Left = RightToLeft.No;

}

else if (selectedItem.Tag.Equals("rmiArabic"))

{

CurrentCulture = new CultureInfo("ar-SA");

Right2Left = RightToLeft.Yes;

}

else

{

return;

}

catch (Exception ex)

{

MessageBox.Show("Change Language Error : "+ ex.Message.ToString());

}

private void CultureChangeFunc()

{

try

{

Thread.CurrentThread.CurrentCulture = CurrentCulture;

Thread.CurrentThread.CurrentUICulture = CurrentCulture;

RightToLeft = Thread.CurrentThread.CurrentCulture.TextInfo.IsRightToLeft ? RightToLeft.Yes : RightToLeft.No;

}

catch (Exception ex)

{

MessageBox.Show("Change Language Error : ", ex.Message.ToString());

}

Best Regards..

[Solved] Filter with DropDown

Hi,

I would like to add a Dropdown in one of my Filtercells. Every entry in the Column should be displayed in this dropdown so the user can choose just elements which are already in the column of the grid. Is there a property to achieve this behaviour or do I have to create a Customcontrol to handle this?

Could you please send me a simple example how to solve this task?

Sincerely,

Dominik Zöbl

RadControl.Font Override

here is the scenario..

I am trying to create some wrapper classes for controls that display text such as labels, etc. What I am seeing is that I am copy and pasting the same font override function for each control.

Is there a recommended way of overriding the RadControl.Font and utilize that? The problem, is the wrapper class can only have a single base class.. MyRadLabel : RadLabel

any pointers would be nice. I hope I am just missing something small that I am not thinking of..

RadLabel <html><color=xxxx>

I'm not using themes in my project yet but I would like this to work as if I were. I'm setting up some RadLabels to contain both the name of the piece of information and the value of it. I.E. RadLabel1.Text = string.Format("<html><color=Navy>Item Number: <color=Black>{0}", theItemNumber);

How can I get the color name for the text at the top of the RadForm (or any control's forecolor that is used to display text)?

Also, where I'm setting the color back to the default for the label, is Black the default or is there some place to find that color as well?

Thank you,

Gary

[Solved] Reseting Image to nothing implementation

Hello,

I'm using Q1 2017 radcontrols for winforms (vb.net).

I have a radporama with a radtile, and a radpropertygrid, with the radtile as selectedobject.

When i set an image to the radtile using the radpropertygrid, everything works fine. But i dont know how to reset the image to nothing. If i select the image in the radpropertygrid, and the press "delete" on my keyboard, nothing happens.

I need a solution without clicking on the square and reset.

Could you help me?

Thanks in advance.

Best regards.
