Calculating a range of User Inputed values (Unspecified amount) in a textbox created grid

In this assignment I have to create a spreadsheet like excel without importing a library. Now So far I created a grid of 26x26 textboxes (USING CODE), created the indexed rows and alphabet indexed columns. (All of this using a class named Cellfields as a template)
Gave the names (A1,A2,A3 etc) to each cell. and created a formula bar up top.
then I created an if statement that if what the user writes.SubString(0) == to "=" (Meaning the start of a formula),
it will then go to a switch to read the other input the user entered, meaning if user enters =Sum(A1:A3) it will calculate the sum of cells A1,A2,A3.
Now since the calculated cells required are unspecified, I am unable to find a solution to how to calculate a range of values online, as all you can find online are how to import libraries.
I Did try a few things but were immediately removed. I am trying to create a method for it however, have been staring at laptop for the past 3 days.

So you already have a matrix of 26x26 Textboxes, I assume they would be arranged in a Grid, say the name of your Grid is "gridCells".
Now, Users will click on a Cell (actually textbox) and then go to the Formula Bar and type a formula. So On GotFocus of the textboxes, let the textbox remain "Selected", in the sense keep the reference at form level also may be Highlight the Border to show that this is the currently selected cell. This will help you know which Textbox to apply the formula.
Now, when someone types "=Sum(A1:A3)" in the Formula Bar, you would parse the formula, identify it is a "Sum" operation and find out the names of the Textboxes A1, A2 & A3.
From your post looks like you are done this far. Now write a function as below (Not bothering about performance etc. right now).
private String GetValueOfCell(String cellName)
{
foreach (var control in gridCells.Children.OfType<TextBox>())
if (control.Name.Equals(cellName))
return control.Text;
return "";
}
Call this function for all 3 Textboxes, like this:
String value = GetValueOfCell("A1");
And if the value is not empty and can be parsed as int/double, keep doing the Sum and finally store the value in the Text property of our highlighted Textbox.
Hint: You might also want to Save the Formula on the highlighted textbox, because this value goes into the Text property you can use the Tag property to hold the formula.

I need a multi-column control that only displays one column in c#

In my project I need a control that allows me to enter 2 columns.
First column is an Id Number
Second column is some Text.
Example...
row 1 Id = 1 Text = Day Shift
row 2 Id = 2 Text = Night Shift
But I only want to display the Text Values and then have the user select either Day Shift or Night Shift.
The program can then just lookup the corresponding value (1 or 2) for whatever text they chose.
- In Microsoft Access I would just have used a ComboBox and hidden the first column.
I cannot find anything in Visual Studio 2017 to put on my Windows Form that easily does this.
I want to set it all up at design time and the closest I have come so far is by using a LISTVIEW control using a display type of LIST (I don't want column headers either.
It seems to do what I want except that it always wants me to leave a blank space below my lines of text - presumably for a horizontal scrollbar even though I set it to False in the properties and it does not actually display a scroll bar.
If I resize the ListView control to just be big enough for my two rows of text it tries to display the 2nd row next to the 1st row and still leaves a blank space below the rows.
See the below images, assuming I uploaded them properly, I am totally new to asking questions here.
Is there a way I can achieve this - should I be using a different control?
The closest I came to what I need is the top image

Thanks and I hope it all makes sense.
In reply to Harry I added the below...
After adding the ListView control to my form I then clicked on the little arrow selector (in the top right of the ListView control).to bring up the collections list popup box.
It is there I set the view to be ‘List’ so I don’t have to have column header, then I clicked on EDIT ITEMS to get another pop-up screen…Click the [Add] button to add items in the rows.
Then I changed the Text to ‘Day Shift’ for the first member (and ‘Night Shift’ for the second member).
To add values in the rows for the 2nd column I then clicked the SUBITEMS (collection) box in properties to get the next popup…
I then clicked the Add button and created a new Text item (value 1)
and repeated this for the Night Shift member but gave it a value of 2.
These values are to be the actual ID values (in the 2nd column).
Note…
I did create column Headers but setting the View to List means I don’t get them displayed (and don’t want them displayed).
but I did notice that changing the View to List also removes the second column (Id) from the ListView display.
As I don’t need the Id values (1 & 2) displayed I am not going to worry about what happened to them disappearing in the display. All I did, though, was just changed the View from Details to List.
Sorry If I’m misunderstanding you but at this point there is no actual code I am creating, no doubt Visual Studio 2017 does that itself but I am not looking at that. Is that what you needed to see?
Hope this makes better sense though, I did try and include images but the system will not let me do that until my reputation points are higher, sorry.
Thanks

c# add objects to table rows dynamiclly

I am trying to do something like this but I don't know how:
I have a table in c# which I increase and decrease during runtime.
Each row contains data, that is being parsed from an object.
I want to get an access to the object that the line is parsing, some a pseudo of it would be:
if (table.row.object == selectedObject)
I can't do it from the row number or something because the rows are being removed and inserted, each time with different objects.
any ideas, please?
EDIT: I am using TableLayoutPanel to work with a table, and this is how I add rows and removes them:
I am adding rows to the table dynamically, I have set of buttons and when I click one it deletes all old rows from the table and adds new rows that are related to this button.
This is the way I add new rows:
tlp.RowCount++;
tlp.RowStyles.Add(new RowStyle(SizeType.AutoSize));
tlp.Controls.Add(new Label() { ... }, cellIDX, rowIDX);
// adding more columns //
and to remove old rows I loop through all rows from bottom to top, removes all related controls of the current cell, then I remove style and row num like so:
tlp.RowStyle.RemoveAt(rowNum);
tlp.RowCount--;
thank you
you can also see a previous question I had related to this subject:
C# change table row color when mouse hover

You can try having a new column in the table (call it original_row_no) and set the row values into that, before you start your insertion/deletion process. That way you can reference the row directly (this is in response to your final line which says "I can't do it from the row number or something because the rows are being removed and inserted, each time with different objects."
A better way is to have a unique id in the table and run your references against that.
It is much more easier to help if you show the code you are trying.

How do I set the content of a label to a database table cell in WPF?

I have built a program in WPF using Visual Basic that allows users to select from a series of items. The list of items may change as I add more items or remove older ones. Originally, I would just add and remove these items in the project code, and rebuild the executable.
Over time, however, the list of items grew and became tedious and impractical to maintain in the code. It occurred to me that it would be easier to store the items in a database table which the program can read, and the list can just be updated by adding and removing items from this database.
I have the database built, and I've added it as a Data Source. I have the data connection set up and everything is ready to go.
What I need to know is how to set the Content property of a label to a cell from a table in the database. I want to do this in the codebehind, not in markup (XAML).
My guess is that I will need to set up a sort of query with a for loop to find the cell I want.
The name of the database is ItemsDB. It contains a table called ItemsTable, and the fields in the table have a unique ID (key) with an AutoNumber data type. The column containing the data I want is named ItemLabel.
So, to sum it all up, I want a label to show the content from a single cell in the database, specified in the codebehind. Either C# or VB is fine.
EDIT
I guess I should've mentioned that the labels themselves actually function as buttons, and I don't really want to display a ListView if I don't have to. I know it's not helpful to not have any code posted, but I don't even know where to start, so there's no code to post.

Took a while longer than I expected, hope this is still useful. So, what you want to do is iterate through a collection and create a new Label for each row.
You will need a container for the Labels, I used WrapPanel, but you can use any Panel you want. I'm replacing your Data Source with a simple DataTable, you'll get the point from this:
foreach (DataRow row in YourItemsTable.Rows)
{
Label newLabel = new Label();
newLabel.Content = row["ItemLabel"].ToString();
// If you need some events, attach the handlers here
yourParentContainerPanel.Children.Add(newLabel);
}
This should be all you need.

How to generate freeform rdlc reports with one page per row

Given a data set containing multiple rows, from within a .NET console application I need to generate a report on a single page for each row, sending those pages directly to the printer.
I am attempting to use Microsoft Report for this by attaching it to a data set and placing TextBoxes where I wish. Generating the report and sending it to the printer are not a problem. Unfortunately, the data only seems to be available in aggregates -- First, Sum, Last, Max, etc. I cannot latch the text box to a bare field.
Some poking around here and other sites seems to address this, but only when the data is presented in a table. One post even said without elaboration, "My mistake was using Text Boxes"
Am I using the wrong tool for what I am attempting to accomplish?

I ran into the same problem and managed to solve it. The solution seems a little convoluted to me so don't quote me on the "right" way to do this, but here is what I did:
Make sure you have a Dataset defined for your report.
Add a "Table" control to the report. This seems to be needed in order to iterate the rows in your Dataset.
Delete the header row and two of the default columns from the table so that you are left with a single row with a single column.
Expand the table to the width of your layout and make it as tall as you will need for your "free form" layout.
By default, there is a TextBox inside the table cell. Right-click the empty table cell and choose "delete" to remove that TextBox.
Drag a "Rectangle" control into the empty table cell. It seems to automatically "dock" to the width/height of the table cell.
Now you should be able to drag the fields from your DataSet (TextBoxes, etc) into the Rectangle to produce the desired layout.
Note that I am in the early stages of using this approach so I'm not sure if I am going to hit any walls... but for a basic report that uses TextBoxes and a page break after each "row" it seems to be working ok.

Or you try to use a list.
In the list you can arange textboxes (and other controls) as you want and they will be filled for each record in the recordset.
This work for me. :-)
