Hi,

Is there a way to hide a tab without removing it from the Pages collection? Can't find a property to do that.

Thanks!

Data binding Formatting the Cells

Hi,

I have a requirement where I have to compare dates which are in the binded data set to grid. The priority column has to be set to a value and format the cell color to red/orange/gree based on the value of Targetdt and warningdate which is available in the datasource binded to the grid.

I am doing the following.

void rGridViewTasks_ViewCellFormatting(object sender, CellFormattingEventArgs e)

        {

                if (e.CellElement.ColumnInfo.Name == "Priority")

{

//if ((DateTime)e.CellElement.RowInfo.Cells["TargetDt"].Value >= DateTime.Now )

//{

// e.CellElement.BackColor = Color.DarkRed;

// e.CellElement.Value = "1";

//}

//else if (((DateTime)e.CellElement.RowInfo.Cells["WarningDate"].Value >= DateTime.Now) &&

// ((DateTime)e.CellElement.RowInfo.Cells["TargetDt"].Value < DateTime.Now))

//{

// e.CellElement.BackColor = Color.DarkOrange;

// e.CellElement.Value = "2";

//}

//else

//{

// e.CellElement.BackColor = Color.DarkGreen;

// e.CellElement.Value = "3";

//}

}



}

the above WarningDate and TargetDt columns are not added as the columns in the grid, hence they are coming as null and giving a exception.

I checked the rowinfo databounditem and it is also null. Please advice.

regards,

Ribbon Bar BackStage View Exception

I am using Telerik Ribbon on my Application's Main Form. which I call from the Login Form within a Separate Thread (i.e. I start a thread, and within that thread, I load Main Form) using Application.Run(new frmMain()). On Main Form's Load Event, I am selecting a tab of Back Stage View dynamically. using following code

mainRibbon.BackstageControl.SelectedItem = bsvTabAccount;
mainRibbon.BackstageControl.ShowPopup(new System.Drawing.Point(0, 56), mainRibbon.RibbonBarElement);

My problem is, if I hit Enter key on back stage view, application throws exception which states,

System.NullReferenceException: Object reference not set to an instance of an object.
at Telerik.WinControls.UI.BackstageViewElement.ProcessKeyboardSelection(Keys keyCode)
at Telerik.WinControls.UI.RadRibbonBarBackstageView.OnKeyDown(KeyEventArgs e)
at System.Windows.Forms.Control.ProcessKeyEventArgs(Message& m)
at System.Windows.Forms.Control.ProcessKeyMessage(Message& m)
at System.Windows.Forms.Control.WndProc(Message& m)
at System.Windows.Forms.ScrollableControl.WndProc(Message& m)
at Telerik.WinControls.RadControl.WndProc(Message& m)
at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Note: Exception does not appear if I click any tab of back stage view before I press Enter key.

Any help would be highly appreciated.

combobox without dropdown.

Hi,

i have a datasource where there is a status column and it is a enumerator having just a status code, I have a requirement that it should show the status text in the grid, but the control should not be a dropdown, it is just a simple text field in the grid.

is this possible to implement something like a combo or lookup but not as a dropdown field?

Callbacks

Hi,

I have the following code, It encrypts the text into my access database but when I reopen the application I get encrypted text on the scheduler (it doesnt decrypt). Is there anything I am missing?

var summarySchedulerMapping = appointmentMappingInfo.FindBySchedulerProperty("Summary");
summarySchedulerMapping.ConvertToScheduler = new ConvertCallback(ConvertSummaryToScheduler);
summarySchedulerMapping.ConvertToDataSource = new ConvertCallback(ConvertSummaryToDataSource);

private object ConvertSummaryToScheduler(object item)
{
return Encryption.Decrypt((string)item);
}

private object ConvertSummaryToDataSource(object item)
{
return (object)Encryption.Encrypt((string)item);
}

Cheers

ResourceMappingInfo Color field

I'm binding to business objects for Appointments & Resources using EventMappingInfo and ResourceMappingInfo which is working ok, however I cannot see a way to add a Color property ResourceMappingInfo. I am grouping by resource in Timeline view. When the UI is displayed the resources all show up as a dark gray colour which is very hard to read. How can I set the colors of the resources?
