Printing grid in loop issue grid data does not refresh

Hi, I have a loop where I am filling the grid and immediatelly print the grid. All printed documents have the same grid values of the last loaded records to the grid DataSource. Is there something I can do to properly print the grid with correct cell values from actual records?

foreach (var run in _runsToPrint)

{

FillReportedAnalytesGrid();

PrintPreview.PrintGrid(rgvReportedAnalytes, run);

}

private void FillReportedAnalytesGrid()

{

var records = provider.GetReportedResults();

rgvReportedAnalytes.DataSource = null;

rgvReportedAnalytes.DataSource = records;

rgvReportedAnalytes.BestFitColumns(BestFitColumnMode.AllCells);

rgvReportedAnalytes.Refresh();

}

public static void PrintGrid(RadGridView view, string run)

{

var document = new RadPrintDocument();

view.Print(false, document);

}

[Solved] How to Prevent focus CommandBarDropDownList

Hi,

I'm creating a usercontrol wich contains a RadCommandbar and an editor (richtext).

The commandbar contains two CommandBarDropDownList and standards radbutton.

I'm trying to prevent dropdownlists from gaining focus when I press tab, but neither can focus on dropdownlists nor tabstop on commandbar working.

Focus is still in my first CommandBarDropDownList.

I even tried https://docs.telerik.com/devtools/winforms/controls/commandbar/how-to/prevent-the-control-from-gaining-focus.

To explain exactly what's suppose to happen, when tab key is pressed the user control should gain focus, the commandbar should be skipped and the editor become the active control (kind of).

Thanks a lot for helping me.

Cf: my userControl

[Solved] Replace DropDown tabs with the system context menu

How to replace DropDown (New tab, Close tab, Close other ...) with the system context menu ( new ContextMenu();).
I got to delete the menu like this:

RadTabbedFormControl.ContextMenuOpening += (obj, arg) => {

arg.ContextMenu.Items.Clear();

};

And to make a new menu, I tried to do it using MouseDown:

e.Tab.Item.MouseDown += (obj, args) => {

if(args.Button == MouseButtons.Right)

{

ContextMenu testMenu= new ContextMenu();

testMenu.MenuItems.Add("Test");

testMenu.Show(e.Tab, new Point(args.Location.X + 5, args.Location.Y - 35));

}

};

But there was a problem with the error (Unable to display ContextMenu in invisible control) when clicking on an inactive tab.

Can you tell me another way?

Manually trigger item validation

Hi, I'm using below code to validate items in the data entry. This event triggers whenever the items lose focus.

dataEntry.ItemValidated += (s, e) =>

{

ContactEntries employee = dataEntry.CurrentObject as ContactEntries;

if (e.Label.Text == "Contact person:")

{

if (employee.contactPerson.Length < 10)

{

Console.WriteLine("validated");

e.ErrorProvider.SetError(s as Control, "Field is required");

if (!dataEntry.ValidationPanel.PanelContainer.Controls.ContainsKey("Contact person:"))

{

RadLabel label = new RadLabel();

label.Name = "contactPerson";

label.Text = "<html><size=10><b><color= Red>Contact person: </b><color= Black>First Name should be between 2 and 15 chars long.";

label.Dock = DockStyle.Top;

label.AutoSize = false;

label.BackColor = Color.Transparent;

dataEntry.ValidationPanel.PanelContainer.Controls.Add(label);

}

else

{

e.ErrorProvider.Clear();

dataEntry.ValidationPanel.PanelContainer.Controls.RemoveByKey("contactPerson");

}

};

On the first page of the data entry, the items contains predefined values, but the data entry is also connection with a binding navigator, allowing users to add a new page. How can I validate these two pages in case the user does not click each item that will trigger the validation?

Is there some way I can trigger the ItemValidated event manually?

Thanks in advance!
