I have almost rounded all my controls but not the RadTabStrips as well as the corner of each of the tab header.
Also the background color is not changed. On the RadGridView I cannot change the column headers background color. Managed to change the border, the shape and other details, but not the background color.

Attached is a screen capture where can be seen in red the RadTabStrip with light gray background. In orange the RadGridView with gray column headers and in blue the small tab header with blue color and not round corners.

Thanks in advance for your help

DropDownListItem with image and text

Hello dear Telerik team.
I am using RadDropDownList to let the user choose from four options. Those options are absolutely static, so I create four dropDownItems hardcoded. Each option has its text and image. I can define each item by a lode like :

var radListDataItem1 = new RadListDataItem();
radListDataItem1.Image = Properties.Resources.SomeImage;
radListDataItem1.Text = "Sometext";
radListDataItem1.Value = someValue;

var source = new BindingList<RadListDataItem>();

source.Add(radListDataItem1);

cmbTriggerType.DataSource = source; //cmbTriggerType is my RadDropDownList

//same for three more items

cmbTriggerType.SelectedIndex = 0;

And now here comes the question! :)
What should I do to cause your control to render each DataItem with both text and image visible?
Thanks in advance.
Artem

RadDateTimePicker won't update when used in a hosted item in RadCommandBar

I have a RadDateTimePicker being used inside a hosted item on a RadCommandBar. It shows up fine, and is operational, but if I set the value on the RadDateTimePicker at runtime, it doesn't update. The value property of the RadDateTimePicker does get updated, just not visually on the form. Is there a workaround for this?

I'm using 2011.3.11.1229 of the Telerik controls for WinForms.

Here is the code I'm using to create the RadDateTimePickers and assign them to the hosted item:

        Dim raddatetimepicker_from As Telerik.WinControls.UI.RadDateTimePickerElement
      Dim raddatetimepicker_thru As Telerik.WinControls.UI.RadDateTimePickerElement

'Create RadDataimePickers
        raddatetimepicker_from = New Telerik.WinControls.UI.RadDateTimePickerElement
        raddatetimepicker_thru = New Telerik.WinControls.UI.RadDateTimePickerElement
        raddatetimepicker_thru.MaxDate = DateTime.Today

        'Format RadDateTimePickers and insert into host
        Dim SizeDTP As New System.Drawing.Size
        SizeDTP.Height = 0
        SizeDTP.Width = 95

        raddatetimepicker_from.MinSize = SizeDTP
        raddatetimepicker_thru.MinSize = SizeDTP

        raddatetimepicker_from.Format = DateTimePickerFormat.Short
        raddatetimepicker_thru.Format = DateTimePickerFormat.Short

        'Assign to hosted item on command bar
        cbhi_from_date.HostedItem = raddatetimepicker_from
        cbhi_thru_date.HostedItem = raddatetimepicker_thru

Here is the code I am using to assign the value, which doesn't cause the RadDateTimePicker to visually update:

        raddatetimepicker_from.Value = DateTime.Now.AddDays(DaysBack * -1)

Any help would be great, don't want to have to fallback to the standard DateTimePicker because I don't believe I can host that in a RadCommandBar. Maybe there is some sort of a "refresh" function I should be using, but I haven't needed to do this in the past when the RadDateTimePicker is just on a regular form instead of inside a hosted item.

BackgroundImage/-color ignored?

In my RadListView the BackgroundImage (and the Backgroundcolor as well) are ignored.
ViewType is IconsView, but this doesn't matter because it is not shown in all ViewTypes.
Is this a bug or what?

Binding an enum in a datatable

I have bound a BindingList holding my business objects to a GridView which displays fine. Then I reset the grid and I converted the list to a DataTable and bind it to a gridview. The business objects have an enum property for which the appropriate string name is displayed when the objects are bound, however only the integer value of the enum is displayed when the datatable is bound. I use the same predefined group of GridViewDataColumns for both scenarios. The extension method generates a datacolumn with the datatype of my enum. What should I do to get the enum string name to display when the datatable is bound? I just want the string in a textbox, this grid is strictly read only.

List<WorkItem> _workitems = new List<WorkItem>();

List<GridViewDataColumn> _workitemColumns = new List<GridViewDataColumn>();

_workitemColumns.Add(new GridViewTextBoxColumn() { DataField = "InstanceID", HeaderText = "Instance ID" });

_workitemColumns.Add(new GridViewTextBoxColumn() { DataField = "StorageObjectID", HeaderText = "Object ID" });

_workitemColumns.Add(new GridViewTextBoxColumn() { DataField = "Document.BatchID", HeaderText = "Batch ID" });

_workitemColumns.Add(new GridViewTextBoxColumn() { DataField = "ReferenceTypeName", HeaderText = "Document Type" });

_workitemColumns.Add(new GridViewDateTimeColumn() { DataField = "CreateDate", HeaderText = "Create Date", ExcelExportType = DisplayFormatType.Custom, ExcelExportFormatString = "MM/dd/yyyy hh:mm:ss" });

_workitemColumns.Add(new GridViewTextBoxColumn() { DataField = "Title", HeaderText = "Title" });

_workitemColumns.Add(new GridViewTextBoxColumn() { DataField = "OwningUser", HeaderText = "Assigned User" });

_workitemColumns.Add(new GridViewTextBoxColumn() { DataField = "Status", HeaderText = "Status"});

#region this works

foreach (GridViewDataColumn curCol in this._workitemColumns)

{

this.workItemsGridView1.Columns.Add(curCol);

}

BindingList<WorkItem> bindingWorkitems = new BindingList<WorkItem>(this._workitems);

BindingSource dbBindSource = new BindingSource();

dbBindSource.DataSource = bindingWorkitems;

this.workItemsGridView1.DataSource = dbBindSource;

#endregion

#region does not work

DataTable workitemsDT = this._workitems.ToDataTable();

foreach (GridViewDataColumn curCol in this._workitemColumns)

{

this.workItemsGridView1.Columns.Add(curCol);

}

foreach(GridViewDataColumn curCol in this._layerColumns[this._selectedLayer])

{

this.workItemsGridView1.Columns.Add(curCol);

}

this.workItemsGridView1.DataSource = workitemsDT;

#endregion

public static DataTable ToDataTable<T>(this List<T> items)

{

var tb = new DataTable(typeof(T).Name);

PropertyInfo[] props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);

foreach (var prop in props)

{

if (prop.PropertyType.IsGenericType && prop.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>))

{

tb.Columns.Add(prop.Name, prop.PropertyType.GetGenericArguments()[0]);

}

else

tb.Columns.Add(prop.Name, prop.PropertyType);

}

foreach (var item in items)

{

var values = new object[props.Length];

for (var i = 0; i < props.Length; i++)

{

values[i] = props[i].GetValue(item, null);

}

tb.Rows.Add(values);

}

return tb;

}

RadMessageBox Problem in RTL mode

Hi,

When using RadMessageBox in RTL mode the last word is always printed in a new line, such that only the upper half of the word is visible (making it impossible to read).

BTW - do you have any plans on releasing a right-to-left Ribbon?

Thanks,
Roy
