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.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
I am trying to keep appending a list of values to lookaheadRunInfo.gerrits until I get a new lookaheadRunInfo.ECJobLink in the while loop,I tried to create a variable “ECJoblink_previous” to capture the previous ECJoblink and create a new list only when they are different and keep appending until ECJoblink_previous changes,I tried as below but its not working,what am I missing?
try
{
Console.WriteLine("Connecting to MySQL...");
conn.Open();
string sql = #"some query";
var ECJoblink_previous ="";
MySqlCommand cmd = new MySqlCommand(sql, conn);
MySqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
//Console.WriteLine(rdr[0] + " -- " + rdr[1]);
//Console.ReadLine();
lookaheadRunInfo.ECJobLink = rdr.GetString(0);
if (ECJoblink_previous == lookaheadRunInfo.ECJobLink)
{
//Keep appending the list of gerrits until we get a new lookaheadRunInfo.ECJobLink
var gerritList = new List<String>();
lookaheadRunInfo.gerrits = gerritList.Add(rdr.GetString(2));
}
ECJoblink_previous = lookaheadRunInfo.ECJobLink;
lookaheadRunInfo.UserSubmitted = rdr.GetString(2);
lookaheadRunInfo.SubmittedTime = rdr.GetString(3).ToString();
lookaheadRunInfo.RunStatus = "null";
lookaheadRunInfo.ElapsedTime = (DateTime.UtcNow - rdr.GetDateTime(3)).ToString();
lookaheadRunsInfo.Add(lookaheadRunInfo);
}
rdr.Close();
}
var lookaheadRunsInfo = new List<LookaheadRunInfo>();
LookAheadRunInfo lookaheadRunInfo;
var i = 0;
var ecJoblink_previous = string.Empty;
while (rdr.Read())
{
if (rdr.GetString(0) != ecJoblink_previous)
{
ecJoblink_previous = rdr.GetString(0);
if (i > 0)
{
lookaheadRunsInfo.Add(lookaheadRunInfo);
}
// Create a new lookaheadRunInfo
lookaheadRunInfo = new lookaheadRunInfo

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>();

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;

I'm trying to populate a generic collection but having problems. I'm trying to populate myBookings, which is supposed to store a List. The methods below should fill myBookings with the correct List but for some reason when I count the result (int c), I'm getting a return of 0. Can anyone see what I'm doing wrong?
// .cs
public partial class _Default : System.Web.UI.Page

Just a guess, but try this:

Thanks for the help in advance!
Put the declarations for the Panel and all the controls that go onto each panel inside your while loop. You're basically re-adding your once instance of Panel ("panelz") over and over again. What you want to do is create a new panel for each row, inside your while loop, along with new instances of each control that sits on the panel.
