C# :: Add Datagridview Column To Listbox Using For Loop
Apr 18, 2014
I need to take a single column and all the rows in the column from a datagridview to a listbox using a for loop. My code is giving me no errors just not showing any data in the listbox.
private void frmProject6_Load(object sender, EventArgs e) {
// TODO: This line of code loads data into the 'enrollmentsDataSet.Enrollments' table. You can move, or remove it, as needed.
this.enrollmentsTableAdapter.Fill(this.enrollmentsDataSet.Enrollments);

Here is my code.
First, I added a checkbox column.
private void addCheckBoxColumn() {
DataGridViewCheckBoxColumn checkColumn = new DataGridViewCheckBoxColumn();
checkColumn.Name = "clmCheck";
checkColumn.HeaderText = "";
checkColumn.Width = 100;
checkColumn.ReadOnly = false;
dgv1.Columns.Add(checkC

I have looked into this and I've also read that I should be able to Config Each column Accordingly.
I'm Currently using this piece of code:
//Change the Headers on the DataGridView2//
dataGridView2.Columns["cashQTY"].HeaderText = "QTY";
dataGridView2.Columns["cashDescription"].HeaderText = "DESCRIPTION";
dataGridView2.Columns["cashSupplier"].HeaderText = "SUPPLIER";
[Code] ....
Currently it does not error, but it also does not Show the DateTime in the GridView when running either..

I have a datagridview with many columns. I want a context menu to show up when user right-clicks on the fifth column (column index = 4).
private void dgv_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e) {
if (e.Button == MouseButtons.Right) {
DataGridView.HitTestInfo hit = dgv.HitTest(e.X, e.Y);
if (hit.ColumnIndex == 4) {
contextMenuStrip1.Show(Cursor.Position);
}
}
}
The problem is, the hit.ColumnIndex value is either 0, -1 or 1, no matter where I click. So the condition never met and the context menu never shows up. Why the values 0, -1 or 1?

I have a lstYourHand that has two cards in it, I loop through the listbox to get the values of both cards. I take the string value of the listbox item (strCardVal) and use a switch to give it an integer value (intCardVal). For some reason, when I run the code, the message Box at the end gives me the value 0 as a result, it does not register me giving it a value in the switch statement. My code is below:
Int32 intCardVal = 0;
String strCardVal;
Int32 intLoopCounter1;
for (intLoopCounter1 = 0; intLoopCounter1 == 1; intLoopCounter1++) {
strCardVal = lstYourHand.SelectedItem.ToString();

I have a data grid view
ProductID|Name|Category|Description|quantity
1|Coat|men|black coat|5
2|Jacket|men|green jaacket|2
3|Pillow|Home|white|10
a user can edit quantity ie productID 1 has quantity 10, and ProductID 2 has quantity 3, it should update once clicked update button. however i must highlight both rows to do it so if i leave the selected cell on product id 3 it will upate only that row. is there a way to update the rows that have been changed when not highlighted.
for (int i = 0; i < dataGridView1.SelectedCells.Count; i++) {
int selectedrowindex = dataGridView1.SelectedCells[i].RowIndex;
DataGridViewRow selectedRow = dataGridView1.Rows[selectedrowindex];
string a = Convert.ToString(selectedRow.Cells["Quantity"].Value);
string b = Convert.ToString(selectedRow.Cells["ProductID"].Value);
//update to database.....
}

Okay so i have everything right accept transfering the selectedindex from listbox in form1 to listbox in form2. I am using the below string item to hold the selected line of the list box, with the intent of recalling and then adding it into the form2 listbox. I get a not implemented error and i can't figure out why. I know the information is moving with the variable item, it just doesn't get printed out to the new listbox.
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
string item = listBox1.SelectedItem.ToString();
Form2 form2 = new Form2();
form2.Show(item.ToString());

My main form I have the following code
[ImportingConstructor]
public MainForm([ImportMany] IEnumerable<AudioPlugin> content)
{
[Code].....
However, when I add to the listbox as shown above in my main form code the results all show on the same line. My understanding was that they should all be treated as separate because of foreach loop but apparently that is incorrect. I have seen mixed things online some showing that its required to use AddRange instead of Add, however, after literally hours of trying to make this work I am still coming up with nothing. I can't seem to get any code to work using the AddRange or am I finding any way to output each results on a separate line.

I have my ListBox working and I'm able to select the items I want to keep. I'm trying to now get the Invert of the current selection for the items to delete.
I tried using:
if (lstLinePatterns == null) return;
for (int i = 0; i < lstLinePatterns.Items.Count; i++)
lstLinePatterns.Items[i].Selected = !lstLinePatterns.Items[i].Selected;
But
.Selected
is giving me an object error.
Is there an easy way to just inverse current selection?
Current Code:
private void btnSelectNonRvt_Click(object sender, EventArgs e)
{
// Unselects any Items to Prevent Infinite Loop
lstLinePatterns.SelectedIndex = -1;
[Code]....

I need to clear a listbox from a class other than the form where it exists. Why this isn't working? I'm getting no error messages when I compile and I am seeing the Console.WriteLine text I also added in the same function. I can call this function from within my form and it behaves as expected. I tried setting the listbox to public despite the fact I wasn't getting protection level errors but that made no difference.
Just to clarify what I'm doing here... I have a form that includes a panel of user controls from another class. So there is a listbox on OtherClass and the listbox is in MyForm. Heres my code:
MyForm
public void ClearListBox() {
Console.WriteLine("echo");
listBox.Items.Clear();
} OtherClass
private void listBox_SelectedIndexChanged(object sender, EventArgs e) {
MyForm mf = new MyForm();
mf.ClearListBox();
}

I am working on a Windows From application on Visual Studio 2010 where i need to use two checkedlistbox that interacts one with the other one. Let say that the first checkedlistbox is for world regions (i.e.):
Asia
Africa
Europe
South America
And let say that the second checkedlistbox is for Countries (i.e.):
Spain
Italy
Romania
Monaco
(all of this belongs to Europe region)
What we need to do is that when the user check on any world region it automatically checks all the countries on that region in the second checkbox, and vice versa if the users check any country on the second checkedlistbox it automatically seconds the region on the first one.
I know that is possible in Java and we know how to do it, but i don't know if C# supports this and how to do it. I was looking on the class information in the microsoft website: [URL] .... but not a concrete example on how to do it.

I'm working on creating a windows form with a listbox, textbox, and 2 buttons (add,remove). I need a way of removing every string matching the contents of the textbox from the listbox. Here's what I have:
for (int i=0;i<listBox1.Items.Count;i++)
{
//...
listBox1.RemoveAt(i--)
}
Seems to work, but I need a way to show a error message once the user clicks 'remove' and no items in the listbox match.

I was working with a richTextBox on setting its font, color and size. I found examples and got that to work. It seems like a kludge to me just to get the size set.
So, now I need to do the same for a listBox. I got the font and color set but cannot get the font size set.
The error I am getting is on line 6 below: listBoxTopLevelChecklist.Font.Size = fontDialog.Font.Size;
VS 2013 Express tells me this property (font.size) is read-only. That was the same error I got on the richTextBox until I found way using the .SelectionFont structure, but the listBox doesn't support that. So, I'm stuck.
Line 8 on is working finr for the richEditBox.
DialogResult result = fontDialog.ShowDialog();
if (result == DialogResult.OK) {
listBoxTopLevelChecklist.Font = fontDialog.Font;
listBoxTopLevelChecklist.ForeColor = fontDialog.Color;
listBoxTopLevelChecklist.Font.Size = fontDialog.Font.Size;

I've changed the listbox foreground color to default application background color so I get: [URL] which is fine but when I select any element I get white background/foreground(or whatever it is): [URL]
How can I change this so I will have the same default color in the second case?
It is a windows store app
Xaml code(listbox is at the end):
<Page
x:Name="pageRoot"
x:Class="ExchangeRate2.MainPage"
DataContext="{Binding DefaultViewModel, RelativeSource={RelativeSource Self}}"

I'm making a simple airline reservation. I have two list boxes one has the section (A, B, C, etc) and the other rows (1, 2, 3, etc). I used two different arrays to put the values into the list box via form unload. The problem I can't seem to figure out is how can I update these seats and inform the user if a seat is taken or not. Lets say a customer takes A-1 (only seat taken). If I try to add someone else there it will inform me that seat is taken and to select another one. If all the seats are taken it'll tell me to put customer into the waiting list.
Also one more thing is that each row has 3 seats, so A-1, A-2, A-3 for example. If say A-1, A-2 are taken when I push a button show remain seats it should show A-3 only. I have a lot od struggle using arrays.

I have a C# WPF program that takes a SQL query and populates a column from an Oracle database into a listbox on the form. I would like to be able to compare all items populated in the listbox, and run a SQL query for each item, populating those values into a different listbox.
So far, I have this code:
string sql2 = "select unique apps.fnd_application_all_view.application_name, fnd_responsibility_vl.responsibility_name, fnd_form_functions_tl.user_function_name, fnd_form_functions.function_name, fnd_form_functions_tl.description, fnd_form_functions.type FROM fnd_compiled_menu_functions, fnd_form_functions, fnd_form_functions_tl, fnd_responsibility, fnd responsibility_vl, apps.fnd_application_all_view WHERE
[code]....
I would like to be able to basically take the "Responsibility_Name" value from the first listbox (lstResponsibilities), which is already populated, and use those values to in the "sql2" query to find the "Function_Name" and populate "Function_Name" in the second listbox (lstFunctions).

Startthread get called to launch to update list box.
a)is it the only way to pass string to the PostMessage?. my concern is that allocate using new in each iteration each time slows it down a bit.
b)does OnAddToListBox look memory leak free?.
c)What is the best way handle m_pThread at the end?. Any way to improve it?.
Code:
UINT CMyDlg::Dump(LPVOID lparam) {
HWND *pHndl = static_cast<HWND *>(lparam);
char buffer[200];
for (int i = 0; i < 100; i++) {
sprintf_s(buf,"user %d, data %s",i, "Connected");
