Hi,

I have created new class inheriting RadButtonElement and using this class on my Ribbonbar QuickAccessToolBar instead of RadButtonElement. When the mouse pointer comes to over button, background of the image does not change. Whereas, it does when i use RadButtonElement. Is it a bug, or i need to handle some events?

Thanks,

Baris

public class MyRadButtonElement:Telerik.WinControls.UI.RadButtonElement

{

private String _blabla;

public MyRadButtonElement(String blabla)

: base()

{

_blabla = blabla;

}

protected override Type ThemeEffectiveType

{

get

{

return typeof(Telerik.WinControls.UI.RadButtonElement);

}

Setting the background color of a cell

I found this link which shows some sample code on how to set the background color of a cell. The selectionmode is FulLRowSelect. I have some code in an event handler for CellFormatting that does this:

if (someConditionIsTrue)

{

	e.CellElement.BackColor = Color.Red;

	return;

}



e.CellElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local);

when certain conditions are met. At first I didn't think it was working, but I noticed when I moved my mouse over a row that should have a cell with a red background, suddenly the background switched to red. As soon as I move my mouse off that row it switches back to it's default color. That's not the behavior I'd like - it should be red regardless of whether the mouse is over that row or not.

What am I missing?

I want to show the new appointment Dialog (advanced) (see pictures attached) rather than the “inline” 3 option ( Save, Cancel, Options) dialog, when you DoubleClick on the RadSchduler to create a new appointment.

Your help will be appreciated.

Thank you

Multiple Cells Selection

I was searching through the samples, but I cannot find a sample code that will enable the user to perform multi cells selection. The user needs to be able to select multiple cell from the same row or other rows. Each selected cells will have different background and foreground color.

Thank you,
Hendra

Collapsing child rows automatically

Greetings,

How could I get the radgridview to display collapsed child rows set. In other words we have a radgridview with rows and child rows but how could we get the child rows collapsed for all initially until the user decides which one to expand.

Thanks and best regards,

G

reordering rows with bound data

When I attempt to enable row reordering with a gridview bound to a DataTable rather than manually adding rows like in the demo application, nothing happens.

Is it possible to make reordering or drag/drop work when bound to a DataTable?

Style for Disabled Button with Image

The default style does not gray out the image on a button that is disabled.

But there are other themes that do gray out the image (such as Desert, Breeze).

I'm making a copy of the default style and making small adjustments. How can I make my custom theme use a gray image for a button that is disabled?

Update From a GridViewDetailElement

Hello,
I was hoping to have the ability to Update my RadGrid from a GidViewDetailElement that was implemented as a User Control. When a user clicks on a row in the RadGrid, a separate UserControl is displayed to show the Details of that Row. I want to have the ability for the User to change a value in one of the fields shown in the Details vVew which will ujpdate the row in the base RadGrid. The code was implemented just like your example of "Custom Views" only that i wrapped the Details view as a User Control in a RadHostItem. I'm able to view the data just fine in the User Control, its just not apparent to me how to now pass updates from this UserControl now back to my RadGrid with this GridViewDetailElement implementation or if its even possible. Appreciate anyone who can help on this. Thanks - Doug

i Have included the main pieces of code in how this was implemented.
Here is the code in my MainForm.c file that defines the detailView GridViewDetailElement for my RadGrid rgDetails.

private void InitializeGridControl()

{

this.rgDetails.TableElement.SetValue(DockLayoutPanel.DockProperty, Telerik.WinControls.Layouts.Dock.Top);

this.rgDetails.TableElement.Margin = new Padding(10, 0, 10, 10);

this.detailView = new GridViewDetailElement();

this.rgDetails.GridViewElement.Panel.Children.Insert(1, this.detailView);

this.detailView.SetValue(DockLayoutPanel.DockProperty, Telerik.WinControls.Layouts.Dock.Bottom);

this.detailView.Margin = new Padding(10, 0, 10, 2);

}

Here is the Class that Defines the GridViewDetailElement (just the relevant code).

public class GridViewDetailElement : GridVisualElement, IGridView

{

private RadGridViewElement gridElement;

private GridViewInfo viewInfo;

public DetailElement detailPanel;

#region Fields

private RadHostItem hostDetailView;

#endregion

#region Initialization

protected override void InitializeFields()

{

base.InitializeFields();

this.UseNewLayoutSystem = true;

this.Padding = new System.Windows.Forms.Padding(10);

this.StretchHorizontally = true;

this.MinSize = new Size(0, 250);

this.MaxSize = new Size(0, 250);

this.DrawFill = true;

this.Class = "RowFill";

this.detailPanel = new DetailElement();

}

protected override void CreateChildElements()

{

base.CreateChildElements();

hostDetailView = new RadHostItem(detailPanel);

this.Children.Add(hostDetailView);

}

public void Initialize(RadGridViewElement gridElement, GridViewInfo viewInfo)

{

this.gridElement = gridElement;

this.viewInfo = viewInfo;

this.gridElement.GridControl.CurrentRowChanged += new CurrentRowChangedEventHandler(GridControl_CurrentRowChanged);

}

public void Detach()

{

this.gridElement.GridControl.CurrentRowChanged -= new CurrentRowChangedEventHandler(GridControl_CurrentRowChanged);

this.gridElement = null;

this.viewInfo = null;

}

public void UpdateView()

{

GridViewDataRowInfo dataRow = this.GridViewElement.GridControl.CurrentRow as GridViewDataRowInfo;

if (dataRow != null)

{

detailPanel.UpdateUCView(dataRow);

}

public RadGridViewElement GridViewElement

{

get { return this.gridElement; }

}

public GridViewInfo ViewInfo

{

get { return this.viewInfo; }

}

#endregion

#region Event Handlers

private void GridControl_CurrentRowChanged(object sender, CurrentRowChangedEventArgs e)

{

this.UpdateView();

}

#endregion

...

}

And Here is my UserControl Code (relevant code only)

public partial class DetailElement : UserControl

{

        public DetailElement()

{

            InitializeComponent();

}

        public void UpdateUCView(GridViewDataRowInfo dataRow)

{

            string statusView;

            if (dataRow != null)

{

                statusView = GetSafeString(dataRow.Cells["State"].Value.ToString());

                switch (statusView)

{

                    case "Running":

                        picBoxStatus.Image = Properties.Resources.start24;

                        break;

                    case "Paused":

                        picBoxStatus.Image = Properties.Resources.pause24;

                        break;

                    case "Stopped":

                        picBoxStatus.Image = Properties.Resources.stop_red24;

                        break;

                    default:

                        picBoxStatus.Image = Properties.Resources.warning16;

                        break;

}

                this.rTxtServiceOwner.Text = GetSafeString(dataRow.Cells["StartName"].Value.ToString());

                this.rTxtServiceType.Text = GetSafeString(dataRow.Cells["ServiceType"].Value.ToString());

                ....

}

private void rChkTrackService_Click(object sender, EventArgs e)

{

        // How Do I pass an update from this CheckBox back to my main Grid ???????????????

}

}

Thanks Doug
