Tulpep Notification Scrollbar

I have a C# application with a Tulpep/Notification-Popup-Window. I need to use the feature of scrollbar. however it wont show when I have a-lot of details to scroll in Notification-Popup. let say if I have 5 items in Notification-Popup the scroll will not visible and when exceeds of 5 it will show the scrollbar"
public void notifyCriticalItems()
{
string critical = "";
con.conDB.Open();
cmd = new MySqlCommand("Select count(*) from vwcriticalitems", con.conDB);
string count = cmd.ExecuteScalar().ToString();
con.conDB.Close();
int i = 0;
con.conDB.Open();
cmd = new MySqlCommand("Select * from vwcriticalitems", con.conDB);
dr = cmd.ExecuteReader();
while (dr.Read())
{
i++;
critical += i + ". " + dr["pdesc"].ToString() + Environment.NewLine;
}
dr.Close();
con.conDB.Close();
PopupNotifier popup = new PopupNotifier();
popup.Image = Properties.Resources.icons8_brake_warning_25px_1;
popup.ContentFont = new System.Drawing.Font("Tahoma", 8F);
popup.Size = new Size(400, 100);
popup.ShowGrip = false;
popup.HeaderHeight = 20;
popup.TitlePadding = new Padding(3);
popup.ContentPadding = new Padding(3);
popup.ImagePadding = new Padding(8);
popup.AnimationDuration = 1000;
popup.AnimationInterval = 1;
popup.HeaderColor = Color.FromArgb(252, 164, 2);
popup.Scroll = true;
popup.ShowCloseButton = false;
popup.TitleText = "CRITICAL ITEM(S)";
popup.ContentText = critical;
popup.Popup();
}

Please consider removing this line:
popup.Size = new Size(400, 100);
This will allow the popup to expand based on your content

Data insert into Excel file

Here this is my code, and tried lot, if i solve one error, another one will occur, here what is the problem to my code? i am going correct or not?
friends am new to this code field, so help me
thanks in advance friends

Ok, here's an example of how to create a connection, call a stored procedure and fill a dataset, which ultimately is what I think you're trying to achieve. You'll obviously need to tweak it for your data but hopefully this will get you on your way:
stringConnectionString = ("Data Source=192.161.0.0;Initial Catalog=kkh_final;Persist Security Info=True;User ID=xx;Password=yyyyyyy");
DataSet objDataSet = new DataSet();
using (SqlConnection connection = new SqlConnection(stringConnectionString))
{
SqlCommand cmd = new SqlCommand("dbo.MyProcedure", connection);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter pdParam = new SqlParameter("#YourParam", SqlDbType.VarChar);
pdParam.Value = pd;
cmd.Parameters.Add(pdParam);
SqlDataAdapter da = new SqlDataAdapter(cmd);
try
{
da.Fill(objDataSet);
}
catch (Exception ex)
{
string error = ex.Message;
}
}

Acces dynamically created controls from other method C#

As you can see, I have already tried to access the Textbox by a FindControl(), But this didn't work. I want the Textbox that has the same last value as the clicked TextBox, I'm trying to do this by cutting the string and paste that in a variable.
Please help.

First of all you are searching for TextBoxes with different names than you create them with (tbAantal... vs. tbaantal...). Together with a recursive Find method that would work.
Neither is that good practice nor is it fast.
Better
Rather than searching for controls by name each time you create them you should implement something that directly let's you retrieve the controls (via some identifier or similar, in your case: via productid).
For example:
Declare a Dictionary<int, TextBox> textBoxes as a local variable. In your loop, add textBoxes.Add(productid, tbAantal); right after your definition of tbAantal.
In btnBestel_Click you can then use this mapping to retrieve the correct TextBox via textBoxes[productid].
I am aware that you don't really have the productid defined in that context.
Instead of using btnname.Remove(0, 6), you should use the Buttons's Tag property and store the productid as extra metadata:
Back in your loop add btnBestel.Tag = productid; at the appropriate position. In btnBestel_Click you can then write textBoxes[(int)button.Tag].
Overall code in that case
Dictionary<int, TextBox> textBoxes = new Dictionary<int,TextBox>();
private void assortiment_Load(object sender, EventArgs e)
{
string lastorder = "Select MAX(idorders) From orders";
string query = "Select * From Product";
var cmd = new MySqlCommand(lastorder, connection);

I am not sure you are giving valid control name for search. For checking you should apply break point on the line, to see if you are getting valid control name.
For searching your required control by name you should look into each parent control recursively. FindControl method can be used for the purpose.
Change this:
Control tbAantalControl = FindControl("tbAantal" + btnname.Remove(0, 6));
With this:
Control tbAantalControl = FindControl(this.Controls, "tbAantal" + btnname.Remove(0, 6));
Method that recursive find your required:
private Control FindControl(Control.ControlCollection controlCollection, string name)
{
foreach (Control control in controlCollection)
{
if (control.Name.ToLower() == name.ToLower())
{
return control;
}
if (control.Controls.Count > 0)
{
Control result = FindControl(control.Controls, name);
if (result != null)
{
return result;
}
}
}
return null;
}

Is there any reason why you can't just make tbAantal a form level variable and then reference that in the btnBestel_Click method?
var tbAantal = null;
private void assortiment_Load(object sender, EventArgs e)
{
string lastorder = "Select MAX(idorders) From orders";
string query = "Select * From Product";
var cmd = new MySqlCommand(lastorder, connection);

var da = new MySqlDataAdapter(cmd2);
var ds = new DataSet();
da.Fill(ds, "Image");
int count = ds.Tables["Image"].Rows.Count;
var y = 3;
for (int i = 0; i < count; i++)
{
var data = (Byte[])(ds.Tables["Image"].Rows[i]["Image"]);
var stream = new MemoryStream(data);

};

};
//other
productid = Convert.ToInt32((ds.Tables["Image"].Rows[i]["idproduct"]).ToString());
//Textbox: Aantal
tbAantal = new TextBox { Size = new Size(107, 20), Name = "tbaantal" + productid};
//label productid
var lblproductid = new Label();
lblproductid.Text = productid.ToString();
//Button: Bestellen
var btnBestel = new Button();
btnBestel.Name = "bestel" + productid;
btnBestel.Text = "Bestellen";
btnBestel.Anchor = AnchorStyles.Right;
btnBestel.Click += btnBestel_Click;
//Voeg controls toe
this.panel.Controls.Add(pbList);
this.Controls.Add(tblPanelList);
tblPanelList.Controls.Add(naam);
tblPanelList.Controls.Add(omschrijving);

gMapControl1.Position = new PointLatLng(float.Parse(Latitude), float.Parse(Longitude));
GMarkerGoogle marker = new GMarkerGoogle(gMapControl1.Position, GMarkerGoogleType.pink);
markersOverlay.Markers.Add(marker);
gMapControl1.Overlays.Add(markersOverlay);
marker.ToolTip = new GMapRoundedToolTip(marker);
marker.ToolTipText = myReader("ClientName");

Looks like your missing this. I have implemented something similar with no issue. I have some working code you can take a look at if this doesnt help.
marker.ToolTipMode = MarkerTooltipMode.Always;
