I got 2 datagrid views, First datagrid 1st col or Index 0 & the Second datagrid 1st col or Index 0.
How can i loop through a specific col in the datagridviews and look for the string values,if it matches with the list then go to a function.
My approach is not working. How can i do this?
private void b_calculate_Click(object sender, EventArgs e)
{
List<string> value = new List<String>() { "AE0", "AT1", "AT2", "AT3"};
value = new List<string>(datagridview1.Columns[0].Index);
List<string> value2 = new List<String>() { "BE0", "BT1", "BT2", "BT3"};
value2 = new List<string>(datagridview2.Columns[0].Index);
//First Combination
if((value.ToString() == "AT1" || value.ToString() == "AE0" ||
value.ToString() == "AT2")
&&
(value2.ToString() == "BT1" || value2.ToString() == "BE0"))
{
gottoFunction1();
}
//Second Combination
if((value.ToString() == "AT1" || value.ToString() == "AT2" )
&&
(value2.ToString() == "BT1" || value2.ToString() == "BT2"))
{
gottoFunction2();
}
}
Here's a routine that iterates through all available rows in both DataGridViews and does the processing shown in your method:
private void b_calculate_Click(object sender, EventArgs e)
{
for (var i = 0; i < dataGridView1.RowCount; i++)
{
if (dataGridView2.RowCount <= i)
break;
var cellFromDG1 = dataGridView1.Rows[i].Cells[0];
var cellFromDG2 = dataGridView1.Rows[i].Cells[0];
if (cellFromDG1.Value == null || cellFromDG2.Value == null)
{
// this could be the empty row that allows you to
// enter a new record
continue;
}
var value = cellFromDG1.Value.ToString();
var value2 = cellFromDG2.Value.ToString();
if ((value == "AT1" || value == "AE0" || value == "AT2") &&
(value2 == "BT1" || value2 == "BE0"))
{
gottoFunction1();
}
if ((value == "AT1" || value == "AT2") &&
(value2 == "BT1" || value2 == "BT2"))
{
gottoFunction2();
}
}
}

I'm creating a BlackJack game in C#, everything (I'm pretty sure) works, before it gets to my Do-While loop(where everything in the actual game happens.) and when it does, it just either freezes or nothing happens at all. I noticed when I get rid of my Do-While loop the game doesn't freeze, so I'm guessing it's in an infinite loop or something, but I'm not sure what to do here.

I'm still sort of new at programming, and this is my first real project. Any help on how I can make my code better and or fix the problem would mean a million to me.
I am trying to make an If statement with two dataGridViews. in my application I have a button on my second form and two button cell dataGridViews on my first form. the application should run like this: the user clicks on a cell from the table and a text from a comboBox in form2 will be transferred to the clicked cell. for some reason I'm getting an error on my if statement in form2.
This is the error that I get:
An unhandled exception of type 'System.NullReferenceException' occurred in Top Shine.exe

Thanks for the help.
I am currently checking if comboboxes and numericupdowns are empty but i am doing it with If statement.
Can you tell me if there is any other faster way of doing it?
Here is current code
private void button1_Click(object sender, EventArgs e)
{
if(comboBox1.SelectedItem != null)
{
if(comboBox2.SelectedItem != null)
{
if(numericUpDown1.Value != 0)
{
if(numericUpDown2.Value != 0)
{
if(numericUpDown3.Value != 0)
{
if(numericUpDown4.Value != 0)
{
string domacin = "" + comboBox1.GetItemText(comboBox1.SelectedItem);
int D_kosevaPrvoPoluvreme = (int)numericUpDown1.Value;
int D_kosevaDrugoPoluvreme = (int)numericUpDown3.Value;
int D_ukupnoKoseva = D_kosevaDrugoPoluvreme + D_kosevaPrvoPoluvreme;
int D_primljenihKosevaPrvoPoluvreme = (int)numericUpDown2.Value;
int D_primljenihKosevaDrugoPoluvreme = (int)numericUpDown4.Value;
int D_ukupnoPrimljenihKoseva = D_primljenihKosevaDrugoPoluvreme + D_primljenihKosevaPrvoPoluvreme;
string gost = "" + comboBox2.GetItemText(comboBox2.SelectedItem);
int G_kosevaPrvoPoluvreme = (int)numericUpDown2.Value;
int G_kosevaDrugoPoluvreme = (int)numericUpDown4.Value;
int G_ukupnoKoseva = G_kosevaDrugoPoluvreme + G_kosevaPrvoPoluvreme;
int G_primljenihKosevaPrvoPoluvreme = (int)numericUpDown1.Value;
int G_primljenihKosevaDrugoPoluvreme = (int)numericUpDown3.Value;
int G_ukupnoPrimljenihKoseva = G_primljenihKosevaDrugoPoluvreme + G_primljenihKosevaPrvoPoluvreme;
int rezultat;
Functions.odrediPobednika(out rezultat, D_ukupnoKoseva, G_ukupnoKoseva);
//SqlConnection con = new SqlConnection(#"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=C:\Users\arist\Documents\VisualStudio2015\Projects\NBA\NBA\NBA.mdf;Integrated Security=True");
//SqlCommand cmd = new SqlCommand("", con);
}
}
}
}
}
}
}
I would use following fail-fast-validation approach with meaningful messages:
private void button1_Click(object sender, EventArgs e)
{
if (comboBox1.SelectedItem == null)
{
MessageBox.Show("Meaningful message, user should know what he has done wrong", "Invalid xyz");
return;
}
else if (comboBox2.SelectedItem == null)
{
MessageBox.Show("Meaningful message, user should know what he has done wrong", "Invalid xyz");
return;
}
else if (numericUpDown1.Value == 0)
{
MessageBox.Show("Meaningful message, user should know what he has done wrong", "Invalid xyz");
return;
}
else if (numericUpDown2.Value == 0)
{
MessageBox.Show("Meaningful message, user should know what he has done wrong", "Invalid xyz");
return;
}
else if (numericUpDown3.Value == 0)
{
MessageBox.Show("Meaningful message, user should know what he has done wrong", "Invalid xyz");
return;
}
// insert code
}
It's neither shorter nor more efficient, but it's easy to read, to debug and most important: the user knows what went wrong. You should also use meaningful control-names.
Of course you could also use one if and concat all conditions with &&, but i'd prefer my first approach for the reasons mentioned above.
bool valid = comboBox1.SelectedItem != null
&& comboBox2.SelectedItem != null
&& numericUpDown1.Value != 0
&& numericUpDown2.Value != 0
&& numericUpDown3.Value != 0
&& numericUpDown4.Value != 0;
if(valid){
//Code
}
The first thing that springs to mind is to use one if statement
if(comboBox1.SelectedItem != null && comboBox2.SelectedItem != null && numericUpDown1.Value != 0 && numericUpDown2.Value != 0 && numericUpDown3.Value != 0 && numericUpDown4.Value != 0)
{
//Code
}
This can also be put onto multiple lines for readability
if(comboBox1.SelectedItem != null &&
comboBox2.SelectedItem != null &&
numericUpDown1.Value != 0 &&
numericUpDown2.Value != 0 &&
numericUpDown3.Value != 0 &&
numericUpDown4.Value != 0)
{
//Code
}
There's not much to optimize there in reference to execution times etc. But the code could be made a bit neater, a start could be something like:
private void button1_Click(object sender, EventArgs e)
{
if(comboBox1.SelectedItem != null &&
comboBox2.SelectedItem != null &&
numericUpDown1.Value != 0 &&
numericUpDown2.Value != 0 &&
numericUpDown3.Value != 0 &&
numericUpDown4.Value != 0)
{
string domacin = comboBox1.GetItemText(comboBox1.SelectedItem);
int D_kosevaPrvoPoluvreme = (int)numericUpDown1.Value;
int D_kosevaDrugoPoluvreme = (int)numericUpDown3.Value;
int D_ukupnoKoseva = D_kosevaDrugoPoluvreme + D_kosevaPrvoPoluvreme;
int D_primljenihKosevaPrvoPoluvreme = (int)numericUpDown2.Value;
int D_primljenihKosevaDrugoPoluvreme = (int)numericUpDown4.Value;
int D_ukupnoPrimljenihKoseva = D_primljenihKosevaDrugoPoluvreme + D_primljenihKosevaPrvoPoluvreme;
string gost = comboBox2.GetItemText(comboBox2.SelectedItem);
int G_kosevaPrvoPoluvreme = (int)numericUpDown2.Value;
int G_kosevaDrugoPoluvreme = (int)numericUpDown4.Value;
int G_ukupnoKoseva = G_kosevaDrugoPoluvreme + G_kosevaPrvoPoluvreme;
int G_primljenihKosevaPrvoPoluvreme = (int)numericUpDown1.Value;
int G_primljenihKosevaDrugoPoluvreme = (int)numericUpDown3.Value;
int G_ukupnoPrimljenihKoseva = G_primljenihKosevaDrugoPoluvreme + G_primljenihKosevaPrvoPoluvreme;
int rezultat;
Functions.odrediPobednika(out rezultat, D_ukupnoKoseva, G_ukupnoKoseva);
//SqlConnection con = new SqlConnection(#"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=C:\Users\arist\Documents\VisualStudio2015\Projects\NBA\NBA\NBA.mdf;Integrated Security=True");
//SqlCommand cmd = new SqlCommand("", con);
}

I am working on a windows phone app, which is a dialer and I have few problems with the predictive text. Predictive text works fine but it's laggy and slow. My code is:
I've put a contact search function in the textbox's text changed event:
private void dialer_TextChanged(object sender, TextChangedEventArgs e)
{
try
{
MainPage.DialerText = dialer.Text;
contactSearch(MainPage.DialerText);
}
catch (Exception f)
{
MessageBox.Show(f.Message);
}
}
ContactSearch function code:
public void contactSearch(string str)
{
try
{
var digitMap = new Dictionary<int, string>() {
{ 1, "" },
{ 2, "[abcABC]" },
{ 3, "[defDEF]" },
{ 4, "[ghiGHI]" },
{ 5, "[jklJKL]" },
{ 6, "[mnoMNO]" },
{ 7, "[pqrsPQRS]" },
{ 8, "[tuvTUV]" },
{ 9, "[wxyzWXYZ]" },
{ 0, "" },
};
var enteredDigits = str;
var charsAsInts = enteredDigits.ToCharArray().Select(x => int.Parse(x.ToString()));
var regexBuilder = new StringBuilder();
foreach (var val in charsAsInts)
regexBuilder.Append(digitMap[val]);
var pattern = regexBuilder.ToString();
//append a ".*" to the end of the regex to make it "StartsWith", beginning for "EndsWith", or both for "Contains";
pattern = ".*" + pattern + ".*";
SearchListbox.ItemsSource = listobj.FindAll(x => x.PhoneNumbers.Contains(str) | Regex.IsMatch(x.FirstName, pattern));
}
catch (Exception e)
{
// MessageBox.Show(e.Message);
}
}
This code works fine but laggy and slow. I need to make it faster. Please suggest some improvements. Thank you.
These solutions can improve it:
1- Don't use Try catch for repeatedly functions:
This can slow down the performance easily, instead try using if else
2 - Use an asynchronous Task:
It's great for not blocking UI and avoids lag and crashes but use a low delay time for your task e.g 50ms;
3- Use other collection types:
As i can see in your code , your dictionary key is int started regularly from 1.
So why don't you use a array or list which are much faster with more items.
Like this:
string[] contacts = {"contact 1","contact 2","contact 3","contact 4"};
Or even a list:
List<string> contacts = new List<string>();
contacts.Add("contact 1");
contact.Add("contact 2");
Note that Changing collection type may increase performance only in huge amounts of data.

I am using Data Grid View.
I have a list of object lets say.
class abc{
public int i{get;set;}
public long b{get;set;}
}
//in Form Load
List<abc> objList = new List();
listpopulate(); // populate the list.
datgridvew.dtasource = objList;
I want to show "-" where Objabc.i value = 0
and want to show "Good" where Objabc.b = 1000
I tried cell default format but in vain.
Can you please help me out ?
You can use an event for that, like:
DataGridView.CellValueChanged Event
Or use DataGridView.CellFormatting Event like this:
private void DataGridView1_CellFormatting(object sender,
DataGridViewCellFormattingEventArgs e)
{
DataGridView dgv = (DataGridView)sender;
if (dgv.Columns[e.ColumnIndex].Name == "i" &&
e.RowIndex >= 0 &&
dgv["i", e.RowIndex].Value is int) &&
(((int)dgv["i", e.RowIndex].Value) == 0)
{
e.Value = "-";
e.FormattingApplied = true;
}
}

HEre you can do using Jquery on clientside
$(document).ready(function () {
$(".GRIDVIEWCLASSNAME").find("td").each(function () {
if ($(this).text() == "0")
{
$(this).html("-");
}
if ($(this).text() == "1000")
{
$(this).html("Good");
}
});
});
