Adding CheckBox to the Group header

I need to add Checkbox to group header.
i was able to do so, altering the code from
http://www.telerik.com/community/forums/winforms/gridview/adding-controls-to-the-group-header.aspx
just needed to inherit from GridGroupContentCellElement class.
but, the checkbox is appearing on the right most side and also i cannot attach to its check state toggle event.

Thank you in advance for your help

the code for the inerited class is

public class CustomGroupHeaderCell : GridGroupContentCellElement

{

public event EventHandler MeCheckChanged;

private RadCheckBoxElement checkbox;

public CustomGroupHeaderCell(GridViewColumn column, GridRowElement row)

: base(column, row)

{ }

protected override void CreateChildElements()

{

base.CreateChildElements();

checkbox = new RadCheckBoxElement();

checkbox.MinSize = new System.Drawing.Size(5, 5);

checkbox.ToggleStateChanged += new StateChangedEventHandler(checkbox_ToggleStateChanged);

Children.Insert(0,checkbox);

ApplyThemeToElement(checkbox, "Bruder");

}

private void checkbox_ToggleStateChanged(object sender, StateChangedEventArgs args)

{

if (MeCheckChanged != null)

MeCheckChanged(this, null);

}

protected override System.Drawing.SizeF ArrangeOverride(System.Drawing.SizeF finalSize)

{

SizeF size = base.ArrangeOverride(finalSize);

RectangleF rect = GetClientRectangle(finalSize);

if (this.checkbox != null)

this.checkbox.Arrange(new RectangleF(rect.Right - this.checkbox.DesiredSize.Width - 5,

rect.Top + (rect.Height - this.checkbox.DesiredSize.Height) / 2,

this.checkbox.DesiredSize.Width,

this.checkbox.DesiredSize.Height));

return size;

}

private void ApplyThemeToElement(RadItem item, string themeName)

{

try

{

if (item.ElementTree == null) return;

DefaultStyleBuilder builder = ThemeResolutionService.GetStyleSheetBuilder(

(RadControl)item.ElementTree.Control,

item.GetThemeEffectiveType().FullName,

string.Empty, themeName) as DefaultStyleBuilder;

if (builder != null)

item.Style = builder.Style;

}

catch (Exception ex)

{ }

}

Reuse a conditional formattings between gridviews

Dear members,

i have 3 grids on 3 forms, but just one gridview is directly visible for the end user, because the other forms are on seperate monitors away from the pc users view.

What i want is, that a condtional rules that is defined for the main grid will be copied to the both others.

Is this supported and if not can i bind for example the rowbackcolor to a my.settings.value?

i have used

Dim obj = New ConditionalFormattingObject("MyCondition", ConditionTypes.Startswtih, "1 -", "", True)
obj.CellForeColor = Color.Red
obj.RowBackColor = my.settings.fcDIV1
Me.RadGridView1.Columns("Name").ConditionalFormattingObjectList.Add(obj)

but i have gotten a null reference exception.

Kind regards

Martin

Progressbar with gradient

Hello,

is there a way to have the RadProgressbarElement show a gradient that only uses part of the defined color range depending on the actual progress (eg. at 50% only BackColor1->BackColor2, at 75% BackColor1->BackColor3, at 100% BackColor1->BackColor4)?

Kind regards,

Andreas

[Solved] CreateCell event cellelement is always null

Hi, this is my first post. I'm using RadGridView and I want some cells have different colour if a condition is fulfilled or some cells disabled if the same condition or another is fulfilled. I am handling CreateCell event but the problem is e.cellelement is always nothing and I get exception. I'm using RadControls for Windows 2010 Q2 SP2 trial.
I'm using Visual Studio 2008 (.NET 3.5 Framework, VB. NET) and I'm new using telerik rad controls.
Am I doing something wrong? Is this event the best for doing what I try to get? Thanks for the answers.

Gridview row index after filtering

Hi guys.

Got some problems with the radgridview. I have a radgridview with some filters. If user filters the data i need to get row index for some updates. But for me row index is always -1 after filtering. Without filtering code works well.

private void grdDetay_CellEndEdit(object sender, GridViewCellEventArgs e)
{

  var listId = 0;
var dtyid = 0;

GridViewRowInfo row = this.grdDetay.CurrentRow;
int rowIndex = row.Index;
listId = Convert.ToInt32(grdDetay.ChildRows[rowIndex].Cells[0].Value);
dtyid = Convert.ToInt32(grdDetay.ChildRows[rowIndex].Cells[1].Value);

}

RadPageView met Task could not find LC.exe SdkToolsPath

HI

I have met a big problem.

I have new a TelerikWinFormsApp1 and the build process is normal.

but after drag/drop a RadPageView into Form1 the build process throw the error :

SeverityProjectCodeDescriptionFileLine
ErrorTelerikWinFormsApp1
Task could not find "LC.exe" using the SdkToolsPath "" or the registry key
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\NETFXSDK\4.6\WinSDK-NetFx40Tools-x86".
Make sure the SdkToolsPath is set and the tool exists in the correct processor specific
location under the SdkToolsPath and that the Microsoft Windows SDK is installed

Just a simple Telerik control drag/drop...
I need to install the Windows 10 SDK ?
(https://dev.windows.com/en-us/downloads/windows-10-sdk)
If need, Why ???

*Registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\NETFXSDK\
is not exists in my windows registry.
*My C:\Program Files\Microsoft SDKs\Windows\ have no 'v10.0A' folder.
*If drag/drop the radButton1, the build process is normal.

Environment:
Windows 7
Visual Studio 2015 Enterprise
Telerik DevCraft 2015 Q2

Best regards

Chris

BackColorChanged event gets fired when the control is inside a RadPageView

I don't understand why but if you place a RadTextBox or a RadTextBoxControl with a BackColorChanged event setup inside a RadPageView the BackColorChanged event is raised before the Form_Load method when you start the app without changing the BackColor of the RadTextBox. If you move the control outside the RadPageView the BackColorChanged event does not get raised which is the expected behavior.

I wonder if this is a known issue?

Any idea how to prevent the BackColorChanged event to get raised when the control is inside a RadPageView?
