ListBox and CustomTabOffsets.Add - c#

I have created a listBox in a form and I'm trying to find a way to add things like name, phonenumber, city in rows but with each name, phonenumber and city i columns. After some searching I found the CustomTabOffsets.Add, but I don't get it how this work and I can't find any tutorial that explain how this work. Is there anyone here that can help me understand this? I guess there is better options for this, but listBoxs is a must in this task. Thanks!
In my UpdateGUI method I only have this to add a name to the listBox
lstSeats.Items.Add(inName);

You need to use ListView for this. Not ListBox
ListViewItem lvi = new ListViewItem();
lvi.SubItems.Add("SubItem");
listView1.Items.Add(lvi);

A bit too late, but - how to make more than 2 column's in ListBox using C#?
lstSeats.CustomTabOffsets.Add(12); // "The integers represent the number of quarters of the average character width for the font that is selected into the list box."
lstSeats.UseCustomTabOffsets = true;
lstSeats.Items.Add("a\tb); // tab character between the items
The custom tab offset integers are quarter of the average character width for the selected font https://support.microsoft.com/en-us/kb/318601

Winform - Not WPF - ListView Currency and Checkbox with C#

Does anyone know how to add a currency to a specific column in ListView, please?
It is easy with WPF but my project is Win form.
CheckBox
I used this code for checkbox, but it only shows checkbox in the first Column.
I want it on 5th Column
listView1.CheckBoxes = true;
Currency
I tried this but it is not good.
ListViewItem viewItem = new ListViewItem(new string[]
{
"£"+emailDetails.Total+".00"
});
ListView in WinForms is a very different animal than ListView in WPF.
For the currency: add a string property to your emailDetails class that formats the currency as desired. I would recommend you format the value once, when you set the Total amount, and then reuse the formatted value in the getter of the new property.
For the checkbox: the only way to have it in a different column than the first is to do custom drawing and draw the combobox yourself. It is more complicated, as you will need to perceive clicks to change the picture of the box, and store the status of every checkbox somewhere.

C# make combobox items remember datagridview.cell.value and datagridview.row of that cell

I have a Datagridview and 18 comboboxes.Each combobox represents a column of the Datagridview.
The point is: when I select a combobox item in the dropdownlist, I'd like the other comboboxes to select the corresponding item. I believe that to do that I have to make the comboboxes remember the row of the item.
At first I tried to make a specific class for it but I'm having some trouble.
Then thought that I could store the row information into the combobox by putting it into value property. But I'm still having troubles.
Keeping in mind that trouble won't ever completely leave me, someone has any tips?
Thank you all so much.
I would try this: use the SelectIndexChanged on the first combobox and get the line index, after that, change the others combobox index by setting them with the index you found. This is the dumbest approach, then you can improve it.

ObjectListView Set first displayed item

Is it possible to programmatically set the first displayed item in a BrightIdeasSoftware ObjectListView?
In other words I want to scroll down the list to make another item than the first in the list displayed at the top.
I cant't find any member that does so.
Found it:
objectListView1.TopItemIndex = n;

Get all Data from ListView and Compare String in C#

I have a ListView in which there are two Columns.
Actually, I want to Get Data From my second Column and then Compare this with my hard Coded message.
E.g At this time, there is a name of Person at first Number in ListView and In Behind Coding, if i have that Specific Name then Count increase and Show me Message that Person Searched.
In Simple words, I want to match the patterns.
It is noted that I am using ListView not GridTableView or Table.
And Sorry about my English, it is not well.
If you want to select the name from the selected row of the list view:
name = listView1.SelectedItems[0].SubItems[1].Text;
If you want to select all results from second column:
foreach( ListViewItem item in listView1.Items )
{
mess += item.SubItems[1].Text.ToString();
}

C# Combobox Displaying Blank Items

I'm coding a combobox in C# and for some reason the items in the drop down don't have text. When I have selected an item, it is shown in the combo box text field (the drop down list is always blank whenever I click the drop down button). The datasource seems bound properly because the proper values are being returned when I select items, and the size of the drop down list will change depending on how many items the datasource has. Everything looks fine except for the fact that it seems like my drop down is populated with a bunch of empty strings, which it clearly isn't since as soon as an item is selected the proper text will display.
This is the relevant code:
if (list.Count > 0)
{
cboCustomers.DisplayMember = "Name";
cboCustomers.DataSource = list;
cboCustomers.ValueMember = "ID";
cboCustomers.SelectedIndex = 0;
}
I have looked for an answer to this but can't find it anywhere...I'm sure it's something really simple, but I can't figure it out. The closest problem I found had an answer suggested to set the display member before the data source, which clearly didn't work.
The list is populated from a database query. This will run on keyUp, the idea is that the list is populated as the person is typing based on the info given. So if I wrote 'S' I'd get a combobox with a dropdown that had all the clients starting with 'S'.
Given you don't have any anomalies in your binding, you are probably being affected by DrawMode property of your ComboBox, which may be set to OwnerDrawFixed or OwnerDrawVariable. Set it to Normal and things should get better.
as soon as an item is selected the proper text will display.
A foreground color the same as the background color will produce the same results you are seeing.
