Drag drop appointment and open dialog after drop

Hi,

I've been following this example which works great
:
http://www.telerik.com/help/winforms/scheduler-appointments-and-dialogs-drag-and-drop-from-another-control.html

What I would like to do is once I have dropped the appointment I would like the apppointment dialog box to open so I can enter some addtional data. I am also using the CustomEditAppointmentDialog example so I can use my own fields etc.

Is this possible, I've tried firing the _AppointmentEditDialogShowing event but can't pas the appointment details ie times etc it comes up with a invalid cast.

Thanks

Problem with init GridViewMultiComboBoxColumn

Hi,

I have problem with GridViewMultiComboBoxColumn. I using the latest version of telerik package (Q1 2012).

I have two objects:

public class Offer

{

public Guid Id { get; set; }

public string OfferNo { get; set; }

public Customer Client { get; set; }

public DateTime? DateFrom { get; set; }

public DateTime? DateTo { get; set; }

}

public class Customer

{

public Guid CustomerId { get; set; }

public string Name { get; set; }

public string ShortName { get; set; }

}

When i set GridViewMultiComboBoxColumn for "Client" property then I have exception: Converter can't convert.
If I dont't set ValuMember property, then is no exception, byt choose object in grid don't work.

public Form1()

{

InitializeComponent();

custs = GridData.GetCustomers(5);

IList offers = GridData.GetGridData(custs);

radGridView1.DataSource = offers;

SetColumns();

}

private void SetColumns()

{

radGridView1.Columns.Clear();

GridViewDataColumn column = null;

for (int i = 0; i < 4; i++)

{

switch (i)

{

case 0:

column = new GridViewTextBoxColumn("Offer no");

break;

case 2:

column = new GridViewDateTimeColumn("Date from");

break;

case 3:

column = new GridViewDateTimeColumn("Date to");

break;

case 1:

column = new GridViewMultiComboBoxColumn("Client");

((GridViewMultiComboBoxColumn)column).FieldName = "Client";

((GridViewMultiComboBoxColumn)column).DataSource = custs;

((GridViewMultiComboBoxColumn)column).DisplayMember = "Name";

((GridViewMultiComboBoxColumn)column).ValueMember = "CustomerId";

break;

}

column.Width = 150;

column.IsVisible = true;

column.ReadOnly = false;

radGridView1.Columns.Add(column);

}

What am I doing wrong?

Best Regards

Databinding SelectedItem/SelectedValue in a DropDownList

Hi guys,

How can i databind the selecteditem/selectedvalue in a Dropdownlist allready bounded to a table.

Table looks like this:
int ID, string Name;

The DropDownlist is binded to a table of values (datasource). The DisplayMember is set to a "Name" and ValueMember is set to "ID".
I want to use the ValueMember in another kind of binding.

So i tried to do like this. radDropDownList1.DataBindings.Add("Value", MyDataObject, "TextID");

But then i found out that the raddropDownList1 do not contain the Property Value, but it have a SelectedValue.

So i tried to do like this. radDropDownList1.DataBindings.Add("SelectedValue", MyDataObject, "TextID");
But this did not work as expected.

So how do i do it?

Regards
Svein Thomas

GridViewMultiComboBoxColumn / GridViewComboBoxColumn FilterMode

Hi All,

I'm using Q3 2001 SP1 and I'm trying to allow users to have an AutoComplete functionality with a GridViewComboBoxColumn element in my GridView.

Documentation here:

http://www.telerik.com/help/winforms/gridview-columns-gridviewmulticomboboxcolumn.html
(at the bottom of the page)

And the API reference here:

http://www.telerik.com/help/winforms/p_telerik_wincontrols_ui_gridviewcomboboxcolumn_filteringmode.html

Suggests that the FilterMode/FilteringMode property should be able filter based on the DisplayMember or ValueMember of the GridViewMultiComboBoxColumn or GridViewComboBoxColumn Control. The only properties I can find with "filter" in the name are:

AllowFiltering
AllowFilteringProperty
Filter
FilterDescriptor
PropertyFilter

Has the property been removed? or do I have to access this property another way?

Thanks
