Telerik Wincontrols Flickering

I am new to Telerik thing and working on an application using Telerik WinForm controls. I am adding user controls dynamically into a panel based on options selected in the main tree. One such user control constitutes a detailed form having lots of fields.

below is the way I am displaying the user control in a panel:

loEntityForm =

new EntityForm(_OwnerID); // User control to be added dynamically

pnlResourceRight.Controls.Clear(); // Clearing existing user controls if any

pnlResourceRight.Controls.Add(loEntityForm);

loEntityForm.Dock =

DockStyle.Fill;

Now this loEntityForm flickers a lot before being properly rendered.

I have used already used one possible slolution in the contructor

i.e

InitializeComponent();

SetStyle(

ControlStyles.UserPaint, true);

SetStyle(

ControlStyles.AllPaintingInWmPaint, true);

SetStyle(

ControlStyles.DoubleBuffer, true);

SetStyle(

ControlStyles.ResizeRedraw);

but it doesn't solve my problem. Please suggest.

Installation problems

Hello,

I'm installed the trial version on one machine successfully. So far its great, and my company will be purchasing the software after we confirm it meets our needs. However, when trying to install the software on another machine I get the following error message:

"The installer has insufficient privileges to access this directory: C:\ProgramData\..\RadControls for WinForms Q2 2010 SP2."

Tried running it as both a standard user and administrator. Tried logging in as administrator. Nothing works.

The system is Windows 7 Professional, 64-bit. I know how to change the permissions so the install will proceed, the problem is the error message does not display the full path. Can you tell me what it is so I can create the directories manually and apply the permissions needed?

[Solved] Filter problem when updated to Q2

I have a telerik grid and wrote a function to allow searching all the Grid text columns, by specifying the filter type and input, the function changes all the text columns filter expressions.

It used to work very well on Q1, in Q2 everything changed.

Function is the following, I need to know how to set filter expressions programmatically in the right way in Q2.

private void SetFilter(GridKnownFunction filterFnType, string searchInput)

{

FilterExpression filter;

string input = searchInput.Trim();

if (!string.IsNullOrEmpty(input))

{

foreach (GridViewDataColumn column in this._GridTextColumns)

{

filter = new FilterExpression(FilterExpression.BinaryOperation.OR, filterFnType, "@FilterEditor1");

filter.Parameters.Add("@FilterEditor1", input);

column.FilterDescriptor = filter;

}

else

{

this.grid_Data.MasterTemplate.FilterDescriptors.Clear();

}

[Solved] Problem with passing value to custom GridDataCellElement.

Hi

I created my custom cell and column:

Cell:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Telerik.WinControls.UI;

using System.Windows.Forms;

using System.Drawing;

using System.Diagnostics;

namespace GridViewUnboundMode

{

public class EditableCheckBoxCellElement : GridDataCellElement

{

private RadCheckBoxElement _chk;

private RadTextBoxElement _txtBox;

private RadLabelElement _lbl;

public EditableCheckBoxCellElement(GridViewColumn column, GridRowElement row)

: base(column, row)

{

}

protected override void CreateChildElements()

{

base.CreateChildElements();

_chk = new RadCheckBoxElement();

_chk.Margin = new Padding(0, 2, 0, 0);

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

_chk.Text = string.Empty;

_chk.ToggleState = Telerik.WinControls.Enumerations.ToggleState.Off;

_chk.ToggleStateChanged += new StateChangedEventHandler(_chk_ToggleStateChanged);

_txtBox = new RadTextBoxElement();

_txtBox.Margin = new Padding(0, 2, 0, 0);

_txtBox.MinSize = new Size(10, 20);

_txtBox.Text = "sss";

_lbl = new RadLabelElement();

_lbl.Text = "Not assigned";

_lbl.Margin = new Padding(0, 4, 0, 0);

_lbl.MinSize = new Size(1, 20);

_lbl.TextWrap = false;

_lbl.Font = new Font(_lbl.Font.Name, _lbl.Font.Size, FontStyle.Italic);

_lbl.ForeColor = Color.Gray;

this.Children.Add(_chk);

this.Children.Add(_lbl);

}

void _chk_ToggleStateChanged(object sender, StateChangedEventArgs args)

{

if (_chk.ToggleState == Telerik.WinControls.Enumerations.ToggleState.On)

{

if (this.Children.Contains(_lbl))

{ this.Children.Remove(_lbl); }

this.Children.Add(_txtBox);

}

else if (_chk.ToggleState == Telerik.WinControls.Enumerations.ToggleState.Off)

{

if (this.Children.Contains(_txtBox))

{ this.Children.Remove(_txtBox); }

this.Children.Add(_lbl);

}

protected override SizeF ArrangeOverride(SizeF finalSize)

{

if (this.Children.Count == 2)

{

this.Children[0].Arrange(new RectangleF(0, 0, 20, 20));

this.Children[1].Arrange(new RectangleF(21, 0, finalSize.Width - 28, 20));

if (this.Children[1] == _lbl)

{ _lbl.MinSize = new Size(Convert.ToInt32(finalSize.Width - 28), 20); }

}

return finalSize;

}

public override object Value

{

get

{

return _txtBox.Text;

}

set

{

_txtBox.Text = value.ToString();

}

public bool IsChecked

{

get

{

return _chk.ToggleState == Telerik.WinControls.Enumerations.ToggleState.On;

}

set

{

if (value)

{ _chk.ToggleState = Telerik.WinControls.Enumerations.ToggleState.On; }

else

{ _chk.ToggleState = Telerik.WinControls.Enumerations.ToggleState.Off; }

}

Column:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Telerik.WinControls.UI;

namespace GridViewUnboundMode

{

public class EditableCheckBoxColumn : GridViewDataColumn

{

public EditableCheckBoxColumn(): base()

{

}

public override Type GetCellType(GridViewRowInfo row)

{

if (row is GridViewDataRowInfo)

{

return typeof(EditableCheckBoxCellElement);

}

return base.GetCellType(row);

}

When I create new row I do something like this:

private void btnAddNewRows_Click(object sender, EventArgs e)

{

GridViewRowInfo rowInfo = this.radGridView1.Rows.AddNew();

int columnIndex = 0;

int rowIndex = rowInfo.Index;

foreach (GridViewCellInfo cellInfo in rowInfo.Cells)

{

cellInfo.Value = string.Format("{0}-{1}", columnIndex, rowIndex);

columnIndex++;

}

The problem is that in this loop when I set GridViewCellInfo.Value to some value, property EditableCheckBoxCellElement.Value is not set to this value.

I also don`t know how to get access to EditableCheckBoxCellElement because I need to control property EditableCheckBoxCellElement.IsChecked.

How can I control values for controls that are inside my EditableCheckBoxCellElement?

Data binding is not an option in my case.

Regards
