I'm trying to do something similar to Richard Slate's Row Details Grid, only instead of trying to use a "details" column, I'd like to be able to format the "Details" space with info more like the RadControls example "Custom Views". Is this possible? Basically formatted like the Custom View example, but shown under the row like the Details Grid example.

delete record at child view on grid view

Hi I am a new user of telerik,

I am currentlying using the grid view extension make by Richard http://www.telerik.com/forums/details-view-under-row-in-gridview

I have a radbutton which will delete a row of data after pressed. I have no issue with deleting a row of data in the master view. I just cannot get my head around with deleting a row of data in the child view. Secondly, I want a check box to appear next to each row both in master and child view. After each check box is checked and the delete button is pressed I would like the checked row to be delete. My data is loaded directly from a local Microsoft sql server

Drop Down Button Width

This is for a tablet and I'm sizing things for fat fingers or that wand. What property do I reference in order to make the drop down button wider (DropDownList)?

(I'm open to a suggestion for a better approach - like a different control - for a touch screen where the user may need to select from a small list of choices.)

Thank you,

Gary

Filtering has slowed down...

Hi Telerik

We have been using RadGridView for ages. Some of our customers have approx 100.000 rows of customers displayed in the grid. We have always gotten good remarks because of the fast filtering in the grids (isLike filtering on Textboxcolumns), however, as of lately it has gotten much slower, even though we have not made changes in code.

Have you made any changes in grid, that could cause it to slow down?

Should it not be lightning fast with 100.000 rows?

I have tried implementing a delayed filtering, so that if the user types "Test" fast, it will only filter once. However, it is giving me a lot of headache - have you seen any examples of people accomplishing this?

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..

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..
