Get information out of customfields in an appointment

I have add a couple of extra fields in a CustomEditAppointmentDialog.

When i select an appointment in the scheduler I want to put the information out of one of the extra

fields in a textbox on my form.



I can reach all the information in the standard fields from Appointment class. But i can't reach the

information of the extra fields created in the CustomAppointment class.



Can someone help me out how i can reach that information?




    private void radScheduler1_AppointmentSelected(object sender, SchedulerAppointmentEventArgs e)
    {
        if (e.Appointment.Description != null)
        {
            labelCalendarCustomerNo.Text = e.Appointment.CustNo; //this does not work
            labelCalendarCustomerName.Text = e.Appointment.Location; //this works
            labelCalendarEnd.Text = e.Appointment.End.ToString(); //this works


            labelCalendarStart.Text = e.Appointment.Start.ToString(); //this works


        }
    }
}





public class CustomAppointment : Appointment

{

public CustomAppointment()

: base()

{

}

private string custNo = String.Empty;

public string CustNo

{

get

{

return this.custNo;

}

set

{

if (this.custNo != value)

Unbound Custom Cell

My need seems fairly straightforward, but after poring through help text, forum postings, example apps, and making many trials, I still can't make the whole picture work--I'm missing a couple of key pieces.

.NET C# Winforms, Telerik 2013.1.321.20

The RadGrid is unbound. The data is populated (so far) through creating a new row with "GridViewRowInfo row = Grid.Rows.NewRow(), and then iterating through the cells of the row and setting the value of the GridViewCellInfo.

I need multiple columns of a custom cell type. Each cell contains a multicolumn combo box bound to a datatable (the same for all cells), a text box or label to display a value, and a button. The combo box should display all the time (as would an individual one on the form), not just when the cell is selected. I need to catch the combo box change, and handle it, potentially through methods on the parent form. The label is display only. The button needs to open a dialog form with access to the info from the cell, and again I need to reach back to the parent form. I need to be able to change the formatting on cell initialization, for the selected cell, and when the data changes. And that's it. No new rows after initialization, no sorting, no filtering, no reordering columns.

I can create the elements in CreateChildElements on the cell, and I can arrange them in ArrangeOverride on the cell. I can do some formatting in the Grid_CellFormatting event.

So these seem to be my stuck places:

o I don't seem to be able to inherit my column from GridViewMultiColumnComboBoxColumn, because I need the combo box to show all the time, not just when the cell is in edit mode. AND because I cannot find a cell element for the Multi Column Combo parallel to GridComboBoxCellElement. I can bind and set up the combo box in Grid_CellBeginEdit, but in that case it only shows when it is in edit mode. So what is my best way to get the combo box set up for the cells? (Bind the datatable, set DisplayMember, and ValueMember, set up the MultiColumn grid dropdown, set an event handler.)

o I need to pass at least three values to the cell--the selected value for the combo box, the value to display in the label, and an ID. I believe I can pass all of these to the cell in a small object or tuple in the Value or Tag,. But how do I get them to populate the objects at the right time? I think I'm having some major misunderstanding between the logical cell and the visual cell. I need to store these values in the logical cell and populate the visual cell at the right time--but how exactly, because what I've tried has made everything confused, and the values changed on all the combo boxes at once.

o What is my best way to handle the SelectedIndexChanged or SelectedValueChanged event on the combo box and the Click event on the button, with access to (ideally) methods on the parent form and values from the cell? (I might be able to pass an object reference to the form or an object on the form in the tag, if there is no direct access to methods and properties of the parent form.)

o What is my best way to handle cell formatting, including formatting the controls within the cell (e.g., combobox backcolor) on initialization, on value changed, and on current? So far I haven't seen how to get to the child controls on the Grid_CellFormatting.

Any help will be greatly appreciated.

Having trouble with this ribbonbar..

Hi everyone,

This is my first time working with the ribbon bar. I created a ribbon form and then added a tab and then a group. It looks fine in the default theme. When i change the theme to one on the right side of the image it looks like the bottom part of the group is cut off. Is this right? Also, why does the title text look like it does?

Thanks for your help!

Editor Control with AutoComplete support for "contains" logic

Hi,

Do you offer a control that is ideally TextBox -based that has AutoComplete functionality, much like "out-of-box" TextBox, but with additional support for "contains" logic, in addition to "starting with" logic?

For example, when typing in "p", both "Pear" and "Apple" would be suggested, as both contain "p".

Or optionally, it could be a ComboBox - based control, but allowing free-form entry by user without having to add entered value to Items collection.

Is my current understanding correct that you guys currently don't have this as TextBox-based, according to: http://www.telerik.com/community/forums/winforms/editors/intellisense-autocomplete-in-textbox-like-in-outlook.aspx ? And that your TextBox only shows one suggestion, even though there could be multiple options for autocomplete?

Thanks!

Telerik.WinControls.UI.DataGroup.Header

Hi,

I have a grid with groupings by customer ID. When I iterate in code through the data groups, the header property is returning the value but the first character is truncated off.

the Text on the group header band shows "Customer ID: 1235" but when i check the group.header value, its returning "235". Every group that has a number does this. the string headers seem to work ok.

Pass Datatable Object to Cell C#

Hi,

I tried to display some charts in a Grid like the attached picture, so I need to pass the data to the cell and I used following code:

Random r = new Random ();

GridServer.Rows.Add ("1");

for (int i= 1; i <= 16; i++)

{

DataTable table = new DataTable ();

table.Columns.Add ("DateTime", typeof (DateTime));

table.Columns.Add ("Value", typeof (double));

table.Rows.Add (DateTime.Now, r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (30), r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (60), r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (90), r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (120), r.Next (100));

table.Rows.Add (DateTime.Now.AddSeconds (150), r.Next (100));

GridServer.Rows[0].Cells[i].Value = table;

}

Basing on the definition, the type of GridServer.Rows[0].Cells[i].Value is object

public class GridViewCellInfo : IEquatable<GridViewCellInfo>

{

// Summary:

// Gets or sets the value.

public object Value { get; set; }

//

}

So the GridServer.Rows[0].Cells[i].Value should get the reference of my DataTable, but the actually value of Value is a empty string.

Is this a bug or anything wrong in my code?

Thanks

Charles

Problems in printing grid with multiline field

I have a gridView in a winform. I have set one of the column "Note" to:
wraptext= true
multiline= true

This is my print button:

private void BtnPrint(object sender, EventArgs e)

{

GridPrintStyle style = new GridPrintStyle();

style.FitWidthMode = PrintFitWidthMode.FitPageWidth;

style.PrintHeaderOnEachPage = true;

this.radGridView1.PrintStyle = style;

this.radGridView1.PrintPreview();

}

despite the above, the result I get, see picture attached, is not the expected one.The multilines field doesn't shows properly the content. Part of the text is out of the visible box.
I have tried with several printers but the problem is always the same.
What I can do to solve this problem?
