How to display employee information in form2 by specifying emp id in form1?

This is my form1 which I designed. When I type emp id in form1's textbox and click on the search button it shows form2.
In this second form I need to carry all the details corresponding to emp id and should display details into corresponding textboxes.
I have created emp table in SQL Server...I would like to pull the employee details from the database based on emp id. This is my code:
form1:
private void btnsearch_Click(object sender, EventArgs e)
{
Form2 f2 = new Form2(tbempid.Text);
f2.Show();
SqlConnection con = new SqlConnection("Data Source=RAJIM-PC;Initial Catalog=Practicing;User ID=sa;Password=RajiSha");
try
{
con.Open();
SqlCommand com = new SqlCommand("SELECT eid,emp_name,mobile_no FROM emp WHERE ID='" + tbempid.Text.Trim() + "'", con);
com.CommandType = CommandType.Text;
DataTable dtb = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(com);
da.Fill(dtb);
if (dtb.Rows.Count > 0)
{
Form2.txtempid.Text= dtb.Rows[0]["eid"].ToString();
Form2.txtempname.Text = dtb.Rows[0]["emp_name"].ToString();
Form2.txtmbno.Text= dtb.Rows[0]["mobile_no"].ToString();
}
FormCollection fc = System.Windows.Forms.Application.OpenForms;
foreach (Form f in fc)
{
if (f.Name == "Form2")
{
f.Update();
}
}
}
catch (SqlException sql)
{
System.Windows.Forms.MessageBox.Show(sql.Message);
}
finally
{
if (con.State == ConnectionState.Open)
{
con.Close();
con.Dispose();
}
}
}
form2:
public partial class Form2 : Form
{
public static string txtempid;
public static string txtempname;
public static string txtmbno;
public Form2(string strtxtbox)
{
InitializeComponent();
tbempid.Text = strtxtbox;
}
}

Looks like your doing all the work for filling out Form2 in Form1, I would suggest moving the code into Form2 and calling it from the Form2's constructor. Not only will this make more sense, but means you will only hit your database once to get the results.
Alternatively, you could pass Form2 your data table from Form1 and use the values in Form2's constructor. Again, saving a second query going to the database.

You can take constructor of form 2 as shown below :-
public Form2(string txtempid, string txtempname, string txtmbno)
{
InitializeComponent();
txtempid.Text = txtempid;
txtempname.Text = txtempname;
txtmbno.Text = txtmbno;
}
and in form 1 :-
var form2 = new Form2(dtb.Rows[0]["eid"].ToString(), dtb.Rows[0]["emp_name"].ToString(), dtb.Rows[0]["mobile_no"].ToString());

You should change Form2 to f2 here:
Form2.txtempid.Text= dtb.Rows[0]["eid"].ToString();
Form2.txtempname.Text = dtb.Rows[0]["emp_name"].ToString();
Form2.txtmbno.Text= dtb.Rows[0]["mobile_no"].ToString();
So it becomes:
f2.txtempid.Text= dtb.Rows[0]["eid"].ToString();
f2.txtempname.Text = dtb.Rows[0]["emp_name"].ToString();
f2.txtmbno.Text= dtb.Rows[0]["mobile_no"].ToString();
Update 1
You are trying to assign those fields to the string variables. However, what you should do is to assign them to relevant textbox controls like this:
Assume you have 3 textboxes named tbempid, tbempname, tbmbno on Form2
f2.tbempid.Text= dtb.Rows[0]["eid"].ToString();
f2.tbempname.Text = dtb.Rows[0]["emp_name"].ToString();
f2.tbmbno.Text= dtb.Rows[0]["mobile_no"].ToString();
Update 2
Due to the protection level, you need to add a function in Form2:
public void SetTextBoxes(string strempid, string strempname, string strmbno)
{
tbempid.Text = strempid;
tbempname.Text = strempname;
tbmbno.Text = strmbno;
}
And change the 3 lines to:
f2.SetTextBoxes(dtb.Rows[0]["eid"].ToString(), dtb.Rows[0]["emp_name"].ToString(), dtb.Rows[0]["mobile_no"].ToString());

The following is a very quick example that I've thrown together of what I suggested above. It does not follow best practice for purposes of simplicity. The areas to concentrate on below is the EmployeeModel class, Form1 and Form2 source.
The idea here is utilize the EmployeeModel class as a container that both forms have access to.
Form 1 acquires the employee information. (Keep in mind, the model class can contain any information you like. It does not have to be reserved for just properties. If you prefer, you can keep a reference to a dataset here.)
Form 2 has a reference to this EmployeeModel class. When the button click event is fired on form1, a new EmployeeModel class object is created and initialized with the relevant information that would be displayed in form2. It is then passed as an object reference using Form2's overloaded constructor.
On the Onload event of Form2, the label.Text properties are initialized with what is contained in the EmployeeModel that was passed as a reference.
This is a very basic implementation and in most real world applications where expandability and maintainability are also factors to consider, a MVP or MVVM WinForms architectural framework is typically used.

Moving Frameless Windows Form via Mouse Drag

I'm new to C# and I've attempted many of the solutions here on StackExchange and I've had no luck in trying to set up a control or the entire form for that matter to left click and drag the entire window. I'm working with a frameless window in visual studio 12. The closest I've come to moving the window is moving a single control with the pastebin component(last response) from this-
How do I make mousedrag inside Panel move form window?
I could only get the panel itself to move with that component.
I've tried most of the approaches but I seem get lost where I am to customize it to my own needs. I've tried WndProc override but it didn't do anything when I attempted to move the form window.
I have two panels I want to be able to drag the window with DragPanel and DragPanel2.
Here is my most recent failed approach trying to use the whole form.

How can I set the panels to left click drag the window?
I've tried all of the methods at the post above and the WndProc method here:
Drag borderless windows form by mouse

If you follow the answer in the link you've posted, it is using the mousemove event, whereas judging by the code you've posted, you're using the mousedown event. The mouse down event is only called once when you press a mouse button, it is not called again if you move the mouse while you keep pressing the button. Whereas the mousemove event is called whenever your pointer moves. So your best bet would be to change your mousedown event with the mousemove event i.e.
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
ReleaseCapture();
SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 0);
}
}
if that doesn't work, you can do something like this in the mousemove event, first create a Point 'prevpoint' and an offset point in the form.
Point prevpoint=new Point(0,0);
Point offset=new Point(0,0);
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
offset.X=e.X-prevpoint.X;
offset.Y=e.Y-prevpoint.Y;
prevpoint.X=e.X;
prevpoint.Y=e.Y;
this.Location = new Point(this.Location.X + offset.X, this.Location.Y + offset.Y);
}
}
I have not tested the above code but that will hopefully give you the basic idea.

First of all you have to create an instance of Form2.
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
private Form2 form2;
public Form1()
{
InitializeComponent();
form2 = new Form2();
}
private void button1_Click(object sender, EventArgs e)
{
String value1 = File.ReadAllText(textBox1.Text);
foreach (string line in value1.Split('\n'))
{
form2.listBox1.Items.Add(line);
}
}
}
}
Your specific error is because of listBox1 is being private. Change it to public and you can access it.
public System.Windows.Forms.ListBox listBox1;
Also since you already have:
using System.Windows.Forms;
You can write
public ListBox listBox1;

You create a new form in your project. Then in that form's code you change the constructor to take a string argument that is the report path.
The code you then use to show that form is:
//CrystalReportForm is your new form.
CrystalReportForm form = new CrystalReportForm(path);
form.Show(); //or form.ShowDialog();

Event:
private void dataGridView1_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
{
string path = dataGridView1.SelectedRows[0].Cells["ReportPath"].Value.ToString();
Form3 form = new Form3(path);
//ReportDocument crystal = new ReportDocument();
//crystal.Load(dataGridView1.SelectedRows[0].Cells["ReportPath"].Value.ToString());
//pass = crystal;
form.Show();
}

How to get event for ComboBox inside of Gridview

How to get event for ComboBox inside of Gridview using C# Windows Application... Anyone Tell me the solution of this problem.....
Thanks in Advance...

check this http://www.eggheadcafe.com/community/aspnet/2/10098379/gridview.aspx

I think you are looking at the wrong place. For value change event, you should use your class's property changed event that is bound to that specific column in the GridView. Because, when you change value in the ComboBoxColumn, it will in turn update the value in the object that is bound to that row.
Example:
Designer generated code
`partial class Form1
{
///
/// Required designer variable.
///
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.dataGridView1 = new System.Windows.Forms.DataGridView();
this.Column1 = new System.Windows.Forms.DataGridViewComboBoxColumn();
this.Column2 = new System.Windows.Forms.DataGridViewTextBoxColumn();
((System.ComponentModel.ISupportInitialize)(this.dataGridView1)).BeginInit();
this.SuspendLayout();
//
// dataGridView1
//
this.dataGridView1.AllowUserToAddRows = false;
this.dataGridView1.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
this.dataGridView1.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
this.Column1,
this.Column2});
this.dataGridView1.Dock = System.Windows.Forms.DockStyle.Fill;
this.dataGridView1.Location = new System.Drawing.Point(0, 0);
this.dataGridView1.Name = "dataGridView1";
this.dataGridView1.RowTemplate.Height = 24;
this.dataGridView1.Size = new System.Drawing.Size(282, 255);
this.dataGridView1.TabIndex = 0;
//
// Column1
//
this.Column1.DataPropertyName = "Value1";
this.Column1.HeaderText = "Column1";
this.Column1.Name = "Column1";
//
// Column2
//
this.Column2.DataPropertyName = "Value2";
this.Column2.HeaderText = "Column2";
this.Column2.Name = "Column2";
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(8F, 16F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(282, 255);
this.Controls.Add(this.dataGridView1);
this.Name = "Form1";
this.Text = "Form1";
this.Load += new System.EventHandler(this.Form1_Load);

this.ResumeLayout(false);

Code Behind
`public partial class Form1 : Form

}
private void Form1_Load(object sender, EventArgs e)

// Column1 is
Column1.DataPropertyName = "Value1";
Column1.Items.AddRange(Enumerable.Range(1, 10).Select(i => i.ToString()).ToArray());
Column2.DataPropertyName = "Value2";
dataGridView1.DataError += new DataGridViewDataErrorEventHandler(dataGridView1_DataError);
dataGridView1.DataSource = (from obj in Enumerable.Range(1, 20)
select new Model() { Value1 = obj, Value2 = ("Value2 #" + obj.ToString()) }).ToList();
}
void dataGridView1_DataError(object sender, DataGridViewDataErrorEventArgs e)
