DATEDIFFDAY(Today(),GetDate(QuoteExpireDate)) QuoteExpireDate is the column in the database. What am i doing wrong?

Images in Dropdown from Resourcefile

Hi,
I keep getting the Error Cannnot convert type 'object' to 'System.Drawing.Image' on the line

element.Image = global::TelerikEditor.Properties.Resources.ResourceManager.GetObject(currCountry)

How would I change this?

private void LoadFlags( Telerik.WinControls.UI.RadDropDownList myDLL, Array Cntrys)

{

myDLL.Items.Clear();

foreach (string currCountry in Cntrys)

{

RadListDataItem element = new RadListDataItem();

element.Text = currCountry;

element.Image = global::TelerikEditor.Properties.Resources.ResourceManager.GetObject(currCountry);

element.TextImageRelation = System.Windows.Forms.TextImageRelation.ImageBeforeText;

myDLL.Items.Add(element);

}

Recurrence data is null

My issues are 2 fold... first, I've created a Custom appointment dialog by implementing the EditAppointmentDialog. My recurrence button is turned on and I can use that interface to set the recurrence properties. When I try to save the data during the ApplySettingsToEvent() event, all of my Recurrence propertes in the targetEvent (RecurrencRule, RecurrenceId) are null. But, in the UI on the radScheduler the recurring appointments show correctly. How do I retrieve my recurrence information so that I may persist this data?

My second issue is that I also have a custom appointment object that enherits from Telerik.WinControls.UI.Appointment. In my radScheduler1_AppointmentEditDialogShowing() event I receive an error of "Unable to cast object type of 'Telerik.WinControls.UI.Appointment' to type 'CoachDashboard.CustomAppointment'". My CustomAppointment class inherits from Telerik.WinControls.UI.Appointment. Why would I get this error? The only difference is that this appointment is a recurring appointment now. It works fine when I don't set any recurrence.

[Solved] Cell padding doesn't work with WrapText

Hello,

I would like to have my gridview cell contents wrap. When I set the column WrapText = true there is no padding around the cells and the text hits the border.

I tried setting the cell padding using the CellFormatting event but then the WrapText doesn't happen and the cell uses ellipse.

Can I have both?

Thanks,
Beth

This does not work

void radGridView_CellFormatting(object sender, CellFormattingEventArgs e)

{

e.CellElement.Padding = new Padding(3, 3, 5, 3);

if (e.ColumnIndex != 0)

{

e.Column.WrapText = true;

}

[Solved] GridviewMaskboxColumn Maxlength

Hi everyone,
I am using radGrid to exibit information of people! one of the fields is Mobile that is thought to be Numeric and limited digits. So I am using GridviewMaskboxColumn by following code :

GridViewMaskBoxColumn mobileColumn = new GridViewMaskBoxColumn();
mobileColumn.HeaderText = "Mobile#";
mobileColumn.MaxLength = 10;
mobileColumn.FieldName = "MobileNo";
mobileColumn.MaskType = MaskType.Numeric;
mobileColumn.Mask = "G";
grid.Columns.RemoveAt(10);
grid.MasterTemplate.Columns.Insert(10, mobileColumn);

Everything's fine but The Maxlength doesn't work! I mean when you want to edit MobileNo, you can enter digits more than 10!
Any ideas?!

Thanks

PropertyGrid Date en-GB Culture

Hi,

I am using a RadPropertyGrid and have set the SelectedObject to be an object with a DateTime property. I would like this DateTime property to be displayed using en-GB culture (formatted as dd/MM/yyyy) but I cannot find a way to change this from the default MM/dd/yyyy.

I assume that I'm missing something fairly obvious! Any help would be much appreciated.

Thanks,

Chris.

[Solved] RadListBox Drag Drop and Scroll Bars

I am implementing drag and drop operations between 2 radlistboxes based on the demo with the DragDropManager...
The implementation works fine but i run into a problem when there are more items in the list than the visible area...
specifically getting the upperbound of the visualitem
source code from demo is...

int UpperBound = visualReplacedItem.Bounds.Height * this.targetListBox.Items.IndexOf(this.replacedItem);

the problem is the second part (index of) could return a large number when a list contains 200 items causing the feedback form to draw off the visible area...

is there a visualitems index or something i can reference instead to keep the feedback form in the visible area of the RadListBox?

My feel is that even the demo would not work properly if the lists contained enough items to cause scrolling...

[Solved] Printing a RadCalendar

What would be the best way to print a RadCalendar? Ideally, I could throw a read-only version of the calendar I created on a report.

The function of my current sub-project is to print out an on-call schedule each month (to be passed around to various departments, etc.). The entry form allows the user to double click a day in the calendar and add an assignment ... and that form looks good. Now I go to print it, and I can't find anything on RadCalendar that allows for printing or easy export to PDF/DOC/image, and I go to Reporting and there is nothing that is easily time-based.

I could create a report kludge of generic textboxes for each possible permutation of the calendar, then do the computations to figure out which box goes in which, then fill it out, but ... geez. Surely there is a built-in way to do this that I'm missing.

Thoughts?

Combining SelfReference and Relation

Hello,
I am trying to do SelfReference and adding relation together in the grid.
I have 2 collection: ProjectTemplate and ProjectTask. Each of these 2 contains selfreference 2 each other and they also have relation between them.Checkout code snipet below.
Note: "ProjectContract" is datacontract containing these 2 collection.
"ProjectContract.TemplateContracts" is ProjectTemplate Collection and"ProjectContract.TaskContracts" is ProjectTask Collection.

radGridView1.MasterTemplate.DataSource = ProjectContract.TemplateContracts;

radGridView1.MasterTemplate.Templates.Add(new GridViewTemplate() { DataSource = ProjectContract.TaskContracts });

radGridView1.Relations.AddSelfReference(radGridView1.MasterTemplate, "ProjectTemplateId", "ParentProjectTemplateId");

radGridView1.Relations.AddSelfReference(radGridView1.MasterTemplate.Templates[0], "ProjectTaskId", "ParentProjectTaskId");

var relation = new GridViewRelation(radGridView1.MasterTemplate, radGridView1.MasterTemplate.Templates[0])

{

RelationName = "TemplateTask"

};

relation.ParentColumnNames.Add("ProjectTemplateId");

relation.ChildColumnNames.Add("ParentProjectTemplateId");

radGridView1.Relations.Add(relation);

I am getting somewhat desirable result. I am getting self hierarchy of ProjectTemplate and relation of template and task. But i am unable to get self hierarchy of Project Task.
Please checkout image attached below for more clarification.

Thanks,

RadMultiColumnCombobox automatically select the first item

Hello!
I have a problem with RadMultiColumnCombobox.
I'm using Telerik Control Q2 2011 and VS 2010.
I have a form like the below code:

            Form f1 = new Form();
            RadDock rd1 = new RadDock();
            rd1.Dock = DockStyle.Fill;
            DocumentWindow dw1 = new DocumentWindow();
            rd1.AddDocument(dw1);
            DocumentWindow dw2 = new DocumentWindow();
            rd1.AddDocument(dw2);
            RadMultiColumnComboBox cbx1 = new RadMultiColumnComboBox();
            dw1.Controls.Add(cbx1);
            cbx1.DataSource = GetAllCountries(); (I get list items in the database)
            f1.Controls.Add(rd1);
            f1.Show();

When I select one item in cbx1 and do a drag-drop action in dw1, cbx1 will always automatically select the first item.
If anyone has a suggestion, please let me know.

Thanks!
