I didn't try anything because I don't know how to do it.

Thank youu.

What if the table binded to the gridview is empty ?? it will be no rows in the gridview so how will the loop will work ?

wooow, it is working now, can you please write it as a soultion so I can accept it.

yes, the problem is that the for loop checks only the first row, it doesn't go through the all rows.

I added what code I have tried

It doesn't work 'System.Windows.Forms.MonthCalendar' does not contain a definition for 'SelectedValue' and no extension method 'SelectedValue' accepting a first argument of type 'System.Windows.Forms.MonthCalendar' could be found (are you missing a using directive or an assembly reference?)

I changed and the error remained

Actually I found the solution now, thank you for your effort

but my question is different from what you all said, I know how to create a textfille and how to write inside it, I want only to know how to choose the name of this file as the input username from the user, why it gives me error in username variable

It give me error in this line string fileName = Username+ ".txt"; for the username

It is required to do it in this way, it is only for practise

where is the if statement ??? how can I check if it matches the textfile or not

dataGridView1.Rows.Add()


Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound.

<pre lang="c#">dataGridView1.Rows.Add();</pre>

any suggestion for the new problem ??? when I add the new row it open a form that contain only this row, how can make this row be added under the all rows ??

this doesn't work, the windows still appear.

No I doesn't

My code is work correctly I am only want to stop displaying the "Enter Parameter Value"

I copy this code and used it exactly but it also show the "Enter Parameter Value"

thaaaaaaaanks alooot, that is work, but the problem now when I add the new row it open a form that contain only this row, how can make this row be added under the all rows ??

DataRow obj = ds.Tables[0].NewRow();
obj[0] = textBox1.Text;
obj[1] = textBox2.Text;
obj[2] = textBox4.Text;
obj[3] = dateTimePicker1.Value;
ds.Tables[0].Rows.Add(obj);
ds.Tables[0].AcceptChanges();


I use this code, now it doesn't give me any error, the form of datagridview is shown but the row doesn't be added and nothing changed in the DGV

There are 4 columns, the DataGridView is filled by DataSet.
How can I define them.

Yes I have rows because the DataGridView is filled by DataSet.
there are 4 columns

exactly same the picture

I have no idea about grouping I am just followed the steps from the source you posted it.

private void Form1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'stockDataSet.Table1' table. You can move, or remove it, as needed.
this.table1TableAdapter.Fill(this.stockDataSet.Table1);
sort("Code");

}
private void sort(string value)
{
DataView dv = new DataView();
dv = new DataView(stockDataSet.Tables[0]);
dv.Sort = value;
dataGridView1.DataSource = dv;
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
sort(comboBox1.SelectedItem.ToString());


}



This code work for me

((DataTable)dataGridView1.DataSource).DefaultView.Sort = "Name";
((DataTable)dataGridView1.DataSource).DefaultView.Sort = "Date";
((DataTable)dataGridView1.DataSource).DefaultView.Sort = "Size";


this one doesn't work..

I didn't write any code for showing all the rows, only I wrote this code for Showing the rows between range of two dates selected from the datetimepickers, so what should I do if I want to display all the rows again after applying this filter ??



private void pictureBox10_Click(object sender, EventArgs e)
{
string From = Convert.ToDateTime(dateTimePicker1.Value).ToString("yyyy-MM-dd HH:mm:ss.ff");
string To = Convert.ToDateTime(dateTimePicker2.Value).ToString("yyyy-MM-dd HH:mm:ss.ff");
table1BindingSource.Filter = string.Format("([{0}] >= #{1}# AND [{0}] <= #{2}#)", "Date", From, To);

}

ReportDocument report = new ReportDocument();
report.Database.Tables[0].LogOnInfo.ConnectionInfo.ServerName = @".\SQLEXPRESS";

report.Database.Tables[0].LogOnInfo.ConnectionInfo.DatabaseName = "Stock";
report.Database.Tables[0].LogOnInfo.ConnectionInfo.IntegratedSecurity = true;
CrystalDecisions.Shared.TableLogOnInfo tLogonInfo = new CrystalDecisions.Shared.TableLogOnInfo();
tLogonInfo.ConnectionInfo = report.Database.Tables[0].LogOnInfo.ConnectionInfo;
report.Database.Tables[0].ApplyLogOnInfo(tLogonInfo);



I tried this one but it give me error, Invalid report file path ( for the line of servername)

private void button1_Click(object sender, EventArgs e)
{

ReportDocument report = new ReportDocument();
TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
Tables CrTables;
report.DataSourceConnections[0].IntegratedSecurity = true;
report.DataSourceConnections[0].SetConnection(@".\SQLEXPRESS", "Stock", true);
report.Load("CrystalReport1.rpt");

//CrTables = report.Database.Tables;
//crystalReportViewer1.ReportSource = report;
}


this one also didn't work, the report still ask for username and password,

I am a beginner in these things .. I don't know how to apply what you said

where should I go to reset the password!!
can you explain the steps for me please !!

where should I write this code report.DataSourceConnections[0].SetConnection(@".\SQLEXPRESS", "Stock", true);

I try the code like this and the problem is same :/

private void button1_Click(object sender, EventArgs e)
{
CrystalReport1 Report = new CrystalReport1();
Report.DataSourceConnections[0].SetConnection(@".\SQLEXPRESS", "Stock", true);
private void button1_Click(object sender, EventArgs e)
{
CrystalReport1 Report = new CrystalReport1();
Report.DataSourceConnections[0].SetConnection(@".\SQLEXPRESS", "Stock", true);
//Report.DataSourceConnections[0].IntegratedSecurity = true;
ConnectionInfo crConnectionInfo = new ConnectionInfo();
crConnectionInfo.UserID = "reem";
crConnectionInfo.Password = "123";
ConnectionInfo crConnectionInfo = new ConnectionInfo();
crConnectionInfo.UserID = "reem";
crConnectionInfo.Password = "123";
}

administrator of What !!! I created the local database in visual Studio.

I don't have username and password for the database, I am using Windows Authentication. What should I do to know the username and password !!

I don't have a username and password for the database, I just wrote anything to be saved as username and password because i don't know from where i can get it, for the servername and databasename yes I am sure of it. for the datasource, i use a crystal report wizard and I use a Dataset in it.
