textbox textchange event to click the checkbox in datagridview

I have a textbox and a datagridview with checkbox. The excel import into datagridview. I add the checkbox into datagridview. I want to input the number into textbox and this number will match the column in datagridview.
please help me!
private void TextBox2_TextChanged(object sender, EventArgs e)
{
}
private void TextBox2_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
if(e.KeyCode==Keys.Enter)
{
button4.Focus();
Button4_Click(sender,e);
textBox2.Focus();
}
}
private void Button4_Click(object sender, EventArgs e)
{
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (row.Cells[3].Value.ToString() == textBox2.Text)
{
row.Cells[0].Value = ((CheckBox)dataGridView1.Controls.Find("DataGridViewCheckBoxCell", true)[0]).Checked;
}
}
}
private void Form9_Load(object sender, EventArgs e)
{
TextBox textBox = new TextBox();
textBox.TextChanged += new EventHandler(TextBox2_TextChanged);
}

Set this property when setting up your DataGridView
dataGridView1.Columns[0].ValueType = typeof(CheckState);
And then in your Event Handler set the cell using this
if (row.Cells[3].Value.ToString() == textBox2.Text)
{
row.Cells[0].Value = CheckState.Checked;
}

C# Handling two buttons within the DataGridView

I'm currently developing a C# project that displays the users' orders.
Now, being that I am new to this I'm asking you to assist me on how I could possibly access the two buttons from within the DataGridView and give them separate functions.
Where I've got at code wise:
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (vHisOrd_BtnDelivered.Selected)
{
}
else if (vOrdHis_Btn.Selected)
{
}
}
DataGridView Image:

You can add DataGridViewButtonColumn to the datagridview and use the cellcontentclick event
Use e.ColumnIndex to determine what code to execute
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
DataGridView dgv = (DataGridView)sender;
if (dgv.Columns[e.ColumnIndex] is DataGridViewButtonColumn &&
e.RowIndex >= 0)
{
//TODO - Button Clicked - Execute Code Here
}
}

use ColumnIndex inteads of row name
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
DataGridView dgv = (DataGridView)sender;
//use index in your gridView
if (dgv.Columns[e.ColumnIndex] == 2)
{
//vHisOrd_BtnDelivered
}
else if (dgv.Columns[e.ColumnIndex] == 3)
{
//vOrdHis_Btn
}
}

Change of the edited cell in a datagridview cell

I have a DataGridView with cells containing strings. If a cell content is changed, I want to change the background of this cell. What event is the best for doing this?
I first tried the CellValueChanged event, but this is even called by clicking this cell without editing the content.
Here is my function code:
private void GVCrs_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
this.GVCrs.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor = Color.Orange;
}

You can try CellBeginEdit and CellEndEdit events,
string beforeValue = "";
private void dataGridView1_CellBeginEdit(object sender, DataGridViewCellCancelEventArgs e)
{
beforeValue = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
}
private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString() != beforeValue)
{
dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor = Color.Red;
beforeValue = "";
}
}
Result;
Hope helps,

How to know a specific checkbox inside datagridview is checked or not?

i had a gridview which has 2 columns , one is textbox column and other is checkbox column, how to know which checkbox is checked .
As shown in image ,suppose any of the checkbox is checked , i want to display that the corresponding text box value to that checkbox.
can anyone help me?i tried the below code , but problem which i am facing is that , the values is getting displayed once i clicked to next checkbox then the previously checked checkbox values is getting displayed..
dataGridView1.CellValueChanged += new DataGridViewCellEventHandler(dataGridView1_CellValueChanged);
void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
object tempObj = dataGridView1.Rows[e.RowIndex].Cells[1].Value;
dataGridView1_CurrentCellDirtyStateChanged(sender, e);
if (((e.ColumnIndex) == 1) && ((bool)dataGridView1.Rows[e.RowIndex].Cells[1].Value))
{
MessageBox.Show(dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString());
}
}

private void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
if (dataGridView1.IsCurrentCellDirty)
{
dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
}
}
private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
if (((e.ColumnIndex) == 1) && ((bool)dataGridView1.Rows[e.RowIndex].Cells[1].Value))
{
MessageBox.Show(dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString());
}
}
these below links helped me to understand the concept of cellvalue_changed and cell_content_click..
http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.cellvaluechanged.aspx
and by the help of these links i finally got the solution to my problem

it is as simple as this
//replace the row number and column name with your own
if ((bool)dataGridView1.Rows[0].Cells["Column1"].Value)
{
//do your work
}

private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
if (e.RowIndex > -1 && e.ColumnIndex > -1)
label1.Text = dataGridView1.Rows[e.RowIndex].Cells["Col1"].Value.ToString();
}

private void dataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex == *someIndex*)
{
DataGridViewCheckBoxCell cell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex] as DataGridViewCheckBoxCell;
if (cell != null)
{
if (cell.EditingCellValueChanged)
{
//CheckBox has been clicked
}
//here how to get the checkBoxCell value
var cellChecked = cell.EditingCellFormattedValue;
}
}
}

Selecting a row of DataGridView programmatically

In my form application, there is a (buttonNEW) that selects NewIndexRow of DataGridView and I want to change index of datagridview with this button.
private void buttonNew_Click(object sender, EventArgs e)
{
if (dataGridView.CurrentRow.Index!=dataGridView.NewRowIndex)
{
dataGridView.ClearSelection();
dataGridView.Rows[dataGridView.NewRowIndex].Selected = true;
label1.Text = dataGridView.CurrentRow.Index.ToString();
}
}
But after clicking the button the index of DataGridView does not change.
What is the problem?

This should work :-
int numofRows = dataGridView.rows.count;
dataGridView.CurrentCell = dataGridView.Rows[numofRows - 1].Cells[0];
Or I think you could also do this :-
dataGridView.CurrentCell = dataGridView.Rows[dataGridView.NewRowIndex].Cells[0];

Try with Linc:
private void buttonNew_Click(object sender, EventArgs e)
{
dataGridView.Rows.OfType<DataGridViewRow>().Last().Selected = true;
}
