[Solved] people picker / contact selector

In a current project we need a people picker (validator - against AD preferably), like the one eg. Sharepoint but can't seem to find one anywhere. Does Telerik provide something like it or does anyone else know of such control/dialog?

Is there anyway I can disable theming?

As I've reported before, the initial load time of my MDI Application is unacceptable. I searched around and found out that most of the initialization occurs in relation to themes. Is there a way I can disable themes for the entire application?

Thanks

[Solved] Performance issue with custom cells.

Hi!

I have to use custom cell to display data but I have problem with performance.

I have 500 rows and when I use my custom cell scrolling is very slow, not fluent.

I made simple test and checked that even if I add only one child control to custom cell, scrolling performance goes down significantly.

Is there any way to improve performance in this kind of scenario?

This is my source code:

public class CustomCell : GridDataCellElement

{

private RadCheckBoxElement _chk;

public CustomCell(GridViewColumn column, GridRowElement row) : base(column, row)

{

}

protected override void CreateChildElements()

{

base.CreateChildElements();

_chk = new RadCheckBoxElement();

_chk.Margin = new Padding(2, 2, 2, 2);

_chk.MinSize = new Size(20, 20);

_chk.Text = string.Empty;

_chk.ToggleState = ToggleState.Off;

this.Children.Add(_chk);

}

protected override Type ThemeEffectiveType

{ get { return typeof(GridDataCellElement); } }

}

namespace PerformanceIssue

{

public partial class Form1 : Form

{

List<MySample> _list;

public Form1()

{

InitializeComponent();

_list = this.GenerateList();

}

private void btnPopulateUnbound_Click(object sender, EventArgs e)

{

GridViewDataColumn col = null;

GridViewRowInfo row = null;

for (int index = 1; index <= 10; index++)

{

col = new CustomColumn();

radGridViewUnbound.Columns.Add(col);

col.Width = 100;

}

foreach (MySample item in _list)

{

row = radGridViewUnbound.Rows.AddNew();

row.Cells[0].Value = item.Property1;

row.Cells[1].Value = item.Property2;

row.Cells[2].Value = item.Property3;

row.Cells[3].Value = item.Property4;

row.Cells[4].Value = item.Property5;

row.Cells[5].Value = item.Property6;

row.Cells[6].Value = item.Property7;

row.Cells[7].Value = item.Property8;

row.Cells[8].Value = item.Property9;

row.Cells[9].Value = item.Property10;

}

radGridViewUnbound.MultiSelect = true;

}

private List<MySample> GenerateList()

{

List<MySample> list = new List<MySample>();

MySample item = null;

for (int index = 0; index < 500; index++)

{

item = new MySample()

{

Property1 = string.Format("Row: {0}, Col: {1}", index, 1),

Property2 = string.Format("Row: {0}, Col: {1}", index, 2),

Property3 = string.Format("Row: {0}, Col: {1}", index, 3),

Property4 = string.Format("Row: {0}, Col: {1}", index, 4),

Property5 = string.Format("Row: {0}, Col: {1}", index, 5),

Property6 = string.Format("Row: {0}, Col: {1}", index, 6),

Property7 = string.Format("Row: {0}, Col: {1}", index, 7),

Property8 = string.Format("Row: {0}, Col: {1}", index, 8),

Property9 = string.Format("Row: {0}, Col: {1}", index, 9),

Property10 = string.Format("Row: {0}, Col: {1}", index, 10)

};

list.Add(item);

}

return list;

}

Regards

Change colors in disabled mode

Hi,

I have a WinForms application that works in 2 modes : Consultation and Modification. When my form is in Consultation mode, I need to set the Enabled property of the MultiColumn ComboBox to false. However, the look of the ComboBox must be the same (White Back COlor with Black text color).

The problem is when I set the property enabled to false, I can't change the properties. The control always has grayish colors (text and border).

How can I set the proper colors to my disabled MultiColumn Combo box?

Thanks in advance
