How to show the new appointment dialog (advanced) when double-clicking rather than the simple inline new appointment dialog?

Hi.

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

Highlighting a sentence

Hi,

I've been playing around now for several hours with the question: What would be the best way to highlight a sentence? Keep in mind some sentences end with "?" or "..." By clicking on a button I would like the next sentence to be highlighted. Has anyone worked on this?

Here's a code I have been working with. However, it only highlights the last word of a sentence, but not the last entire sentence.

private void radButtonElement1_Click(object sender, EventArgs e)

{

this.radRichTextBox1.ChangeTextHighlightColor(System.Drawing.Color.White);

this.radRichTextBox1.Document.Selection.Clear();

this.radRichTextBox1.Document.Selection.AddSelectionStart(myNewSentenceStartPos);

myEndPos.MoveToCurrentWordEnd();

do

{

string word = myStartPos.GetCurrentSpanBox().Text;

if (word.Contains("."))

{

DocumentPosition wordEndPosition = new DocumentPosition(myStartPos);

wordEndPosition.MoveToCurrentWordEnd();

this.radRichTextBox1.Document.Selection.Clear();

this.radRichTextBox1.Document.Selection.AddSelectionStart(myNewSentenceStartPos);

this.radRichTextBox1.Document.Selection.AddSelectionEnd(wordEndPosition);

this.radRichTextBox1.ChangeTextHighlightColor(System.Drawing.Color.Aqua);

myStartPos = myEndPos;

myNewSentenceStartPos = myEndPos;

break;

}

else { }

}

while (myStartPos.MoveToNextWordStart());

}

How can I set the start of the selection to myNewSentenceStartPos ?

Thank you,
Karl

Gridview summary row conditional sum

I am still using a trial version of GridView to get an idea how powerful the control is. So, far everything is going good except I have no idea how to handle following situation.
The data is as follow

stock1 B 15
stock1 S 45
stock1 B 67
stock1 S 2

Where S-Sell and B-Buy. While grouping on column 1 (stock1) I need to display the position in stock1. But to do that while summing up the result the sell qty should be considered negative. How can I customize this sum operation?
