Can anyone help me on how can I do auto suggest on gridview when typing on textbox. Almost 1 week I seek for the solution. I already check my select statement, it connect to my database. And now I do not know why that coding is not function. Please somebody help me. This is my current code:

Make these changes within your code:
You are setting dataGridView1.Visible = false; at various places within your code, remove all of them for instance, just for the sake of testing, you can add them later based on your requirements.
Remove this part of query where not [recsts] = 'R' order by empno" because for now it is useless and I don't understand why you are using this, you can apply filters later and also select ... from m_employee instead of [dbo]... etc..
Instead of dataGridView1.SelectedRows[0].Cells[0].Value.ToString(); get data from selected row like this: textBoxName.Text = dataGridView1.Rows[e.RowIndex].Cells["name"].Value.ToString(); Because in future, if you increase/decrease the number of columns or re-arrange the order of getting data, it will not effect.
I've tested your code with these modifications and it works perfectly.

I am working on c# windows form where i have to show a trend for sql server data coming in on different date and time. There are two parameters one is DATESTR which is on X-axis and second is Values which is on Y-axis . Tooltip is only showing Y-axis values but unable to show X-axis Values. In chart, it is showing 0 as the value of x axis.
C# winform application: i added buttons in datagridview in every row for (update,delete). it works fine but when i search data in this gridview the buttons doesn't work on search results.
Here is my code.

We want to attach a combo box into a cell of data grid view. Now it works with mouse click. but for faster moving of form we need it to work using keyboard.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
void CreateGrid()
{
DataTable dt = new DataTable();
dt.Columns.Add("EmpName", typeof(string));//0
dt.Columns.Add("EmpID", typeof(int));//1
dt.Columns.Add("PhoneNo", typeof(string));//2
dt.Columns.Add("Address", typeof(string));//3
dt.Columns.Add("Email", typeof(string));//4
dataGridView1.DataSource = dt;
dataGridView1.Controls.Add(comboBox1); // Add System.Windows.Form.ComboBox in Datagridview
}
private void Form1_Load(object sender, EventArgs e)
{
CreateGrid();
fillRecords(1);
}
string SQL;
void fillRecords(int QueryNo)
{
SqlConnection con = new SqlConnection(#"Data Source=APPLE-PC\RNS;Initial Catalog=DemoDatabase;User ID=sa;Password=rns11");
con.Open();
if (QueryNo==1)
{
SQL = "Select EmpName,EmpID from EmployeeMaster";
}
else if (QueryNo==2)
{
SQL = "Select PhoneNo,Address from EmployeeMaster where EmpID=" + comboBox1.SelectedValue.ToString();
}
SqlDataAdapter da = new SqlDataAdapter(SQL, con);
DataTable dt = new DataTable();
da.Fill(dt);
con.Close();
if (QueryNo == 1)
{
comboBox1.DataSource = dt;
comboBox1.DisplayMember = "EmpName";
comboBox1.ValueMember = "EmpID";
}
else if (QueryNo == 2)
{
dataGridView1.CurrentRow.Cells[1].Value = comboBox1.SelectedValue.ToString();
dataGridView1.CurrentRow.Cells[0].Value = comboBox1.Text;
DataRow dr=dt.Rows[0];
dataGridView1.CurrentRow.Cells[2].Value = dr["PhoneNo"];
dataGridView1.CurrentRow.Cells[3].Value = dr["Address"];
}
}
private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
{
//Visible Location on Current Cell
if (dataGridView1.CurrentCell.ColumnIndex==0)
{
comboBox1.Visible = true;
comboBox1.Location = dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true).Location;
comboBox1.Size = dataGridView1.CurrentCell.Size;
}
}
private void dataGridView1_CellLeave(object sender, DataGridViewCellEventArgs e)
{
if (dataGridView1.CurrentCell.ColumnIndex == 0)
{
comboBox1.Visible = false;
}
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
if (comboBox1.SelectedValue.ToString()!="System.Data.DataRowView")
{
fillRecords(2);
}
}
}
this solution is given by Sinisa Hajnal.
It should work using keyboard, but usually need to press F2 first to enter edit mode. I can solve this by handling CellEnter event and opening edit mode for combobox and setting focus to it inside.
`
private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
{
if (dataGridView1.CurrentCell.ColumnIndex==0)
{
comboBox1.Visible = true;
comboBox1.Location = dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true).Location;
comboBox1.Size = dataGridView1.CurrentCell.Size;
comboBox1_SelectedIndexChanged(null, null);
comboBox1.Focus();//focus on Combobox
}
}

Here is the screenshot:
in above picture, when the form load, the date in combobox 1 is 9/22/2013.
in above picture, i just wanted to change the date in combobox 1 to 9/24/2013, but it change the date in combobox 2 too.
How to fix it? Thanks
It's because you use the same DataSource _datetime for both comboboxes:
comboBox1.DataSource = _dateTime;
comboBox2.DataSource = _dateTime.ToList();
However I think _dateTime may be not what you want to set as DateSource for both the comboboxes, if it's the case, just leave some comment.
I getting an several errors after i change the files name. From default form name (Form2.cs), (Form1.cs) etc to the System.cs, LoginPage.cs and while i change back to the default form name (Form2.cs), this is what happens, the errors appears. What should i do? Is there any solution that i can back this problem to the time before i changed the files name?

The error on "Form1.cs" is:
"Sell_System.Form1.cs" does not contain a definition for "Drawing"
Try to take a look at the designer class (designer.cs), maybe the designer class is still referencing the old file name?
