Hi All-

The Bing! Maps accessible through the Telerik provider are VERY out of date and the OpenStreetsMap provider documentation does not illustrated how to perform the same functionality as is available for the Bing! provider.

How do we access up-to-date maps in Bing! or where can I find documenation on how to implement search and route functionality using OpenStreetMaps provider?

Thank you!

Recurrence Exception problem in custom EditAppointmentDialog

Hello,
I need a recurring functionality for my project. Also I have created a custom EditAppointmentDialog, as well as a custom Appointment class derived from Telerik.WinControls.UI.Appointment. I need one custom field for my appointment.

Everything works fine except two scenarios.

1. At first I create a recurrence appointment which generates a number of occurrences in the scheduler view. Then clicking on one of the occurrences in the scheduler I get a Message Box which allows me to select whether I would like to open this occurrence or the whole series. I select "Open this occurrence". After that LoadSettingsFromEvent() method is called. In that method I have the following code.

protected override void LoadSettingsFromEvent(Telerik.WinControls.UI.IEvent sourceEvent)

{

base.LoadSettingsFromEvent(sourceEvent);

var workSchedule = sourceEvent as WorkSchedule;

if (workSchedule != null && !string.IsNullOrEmpty(workSchedule.WorkScheduleType))

{

cbbxType.Text = workSchedule.WorkScheduleType;

}

}

The sourceEvent object could not be casted to WorkSchedule (a derived class from Telerik.WinControls.UI.Appointment which holds my custom field WorkScheduleType), however it is not null and is easily casted to Telerik.WinControls.UI.Appointment class. that's why I cannot read and set this WorkScheduleType field which I certainly need for this occurrence.

It happens only when a recurrence exception is generated. If it is a normal or recurring appointment everything works just fine.

2. I want the following scenario. I would like to create a recurring appointment (say each week on Mondays and Thursdays at 6 p.m. I would like to go to the gym). I create a recurring appointment which generates a number of occurrences in the scheduler view. Then I want to remove a single occurrence for the next week for Thursday (I have different plans for next Thursday). I click on that occurrence in the scheduler. After that I try to delete this occurrence. The view shows me that it is deleted, however when I recheck DB and then reopen scheduler nothing changes. However an exception in DB is created.

How may I properly implement the above mentioned process?

Editor Validated and Validating events

I noticed that my below code which associates event delegates with a cell textbox editor does not signal those events. Could you please assist ?

private void Grid_CellEditorInitialized(object sender, VirtualGridCellEditorInitializedEventArgs e)
{

            switch (column.Name)
            {
                case "Column1":

                        VirtualGridTextBoxEditor editor = (VirtualGridTextBoxEditor)e.Editor;
                        RadTextBoxElement elmnt = (RadTextBoxElement)editor.EditorElement;
                        elmnt.Tag = editor;
                        editor.Validated += Editor_Validated;
                        editor.Validating += Editor_Validating;

-----------------------------------

private void Editor_Validating(object sender, CancelEventArgs e)
{

                   // NOT TRIGGERED
        }
        private void Editor_Validated(object sender, EventArgs e)
        {

// NOT TRIGGERED
}

Treeview node visible or filter

I would like to hide/unhide nodes based on a bound data source item value. In my sample project, I can assign a full data source and a filtered data source from 'All Data Source' button click or 'Filtered Data Source' button click. But hide and unhide using the node visible property in radTreeView1_NodeFormatting event triggered from the 'Visible = Primary (Hide)' and 'All Visible Unhide' don't work. Also, the first click of 'Visible=Primary(Hide)' only formats the first 5 nodes. It seems once a node's visible property is false, you can not set it to true programmatically. I do not want to refresh or reload the tree view.

It would be really great if there was some way to filter tree view based on Tag versus Text property. Then I could simply populate the tag with true or false and filter.

Value cannot be null. Parameter name: value

Hi Team,

I'm facing this error "Value cannot be null. Parameter name: value" when i import the "docx" to richtextbox. I refer this Link for sample code. I can read below code for some file but some are not.

Here is sample Code

private void button1_Click(object sender, EventArgs e)

{

RadDocument document = new RadDocument();

IDocumentFormatProvider provider = new DocxFormatProvider();

OpenFileDialog openDialog = new OpenFileDialog();

openDialog.Filter = "Documents|*.docx";

openDialog.Multiselect = false;

DialogResult dialogResult = openDialog.ShowDialog();

if (dialogResult == System.Windows.Forms.DialogResult.OK)

{

using (Stream stream = openDialog.OpenFile())

{

document = provider.Import(stream);

radRichTextBox1.Document = document;

}

I do not know this is the file issue or not. I'm using V2011.3.11.1219 WinForms. I attached the file that can not read from code. You need to change the extension to docx.

Regards,

RichTextEditor

Screen Position of a cell

Hi Telerik,

In RadGridView, it was possible to use

cell.PointToScreen(cell.BoundingRectangle.Location)

to obtain the current screen position of a cell. What is the equivalent approach in RadVirtualGrid to obtain a cell's top/left from screen's point of view ?

Thank you,

Saj.

RadButton and Tooltips

Greetings Telerik,

I just tried to add a tooltip-text to a RadButton (image only), but i don't see any property for this. I assumed there's this possibility since there is a property named "ShowItemToolTips" (which is set to yes).

Is this a bug or doesn't it exist?

Many thanks,
Daniel

gridview group by column

Hi. First, thank you beforehand. I have a problem and I do not know how to do it. I have a gridview in which, through a query, I get results in a column of player names, and another column of teams. Each player can belong to a team, but there may be players who do not belong to any team. In my interface I have a button, which when I press it, should show me in my gridview a grouping in the first column of the players belonging to the same team. And those who do not have a team, do not group them into any group, that is, I put them for example down groups of teams formed by players.
Could you tell me how to do this ???

Example:
Name Team

J1 TeamA
J2 TeamB
J3 TeamC
J4 TeamA
J5 TeamB
J6
J7
J8 TeamC

Result in my GridView: Push Button

Name Team
+TeamA
J1 TeamA
J4 TeamA
+ TeamB
J2 TeamB
J5 TeamB
+ TeamC
J3 TeamC
J8 TeamC
J6
J7

Cell borders disappear for GridViewCommandColumn

Hi,

I have a GridViewCommandColumn with buttons that are not always visible (using e.CellElement.Visibility = ElementVisibility.Hidden). When they are not visible the border lines around the cell disappear (see image 1).

I tried to fix this using EnableCustomDrawing=True and subscribing to the CellPaint event and draw the border manually, but this does not seem to work. In fact the CellPaint event seem to happen BEFORE the buttons is drawn. I came to this conclusion by drawing a black border around all cells, and got the result in image 2.

How can I fix this missing border problem?
