Re: C#: How to retrieve text from dgView cell and displayit in the button? - C# Discussion Boards

Hmmm, have you tried Code Project.

I hear some good things about them.

Seriously, look in the Article Archives and there is just about all you need.

create an event for the gridview like so;

private void dgv_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{

//runs when the mouse is clicked over a cell
if (e.RowIndex > -1 && e.ColumnIndex > -1)
{
if (e.Button == MouseButtons.Left)
{
//single-click left mouse button
if (dgv.SelectionMode != DataGridViewSelectionMode.CellSelect)
{
dgv.SelectionMode = DataGridViewSelectionMode.CellSelect;

int row = dgv.CurrentCell.RowIndex;
int col = dgv.CurrentCell.ColumnIndex;

}
}
textbox.text=dgv.Rows[row].Cells[col].Value.ToString();
}
Remeber to Create the same event in the Form.Designer.cs file for the Datagridview.
Hope this Helps

Hi Enobong Adahada

thanks for replying to my message, I have managed to work around my code refering to the question I posted yesterday
but for some reason its not getting the cell value number to display it in the button.
If you dont mind please you can have a look my question (under the View Unanswered Question) provided with sample of code
and tell me if I missing something....

Thanks in advance

kind regards

roni

Can you post the code u are using so i can
see if there are logic bugs.

Here is the code...

I have two forms on my project (Form1 & Form2).

-In Form1 I have two Buttons (Starter & Main). Both these buttons on click event, they call database sql-query and genereate into form the records as Buttons.
-In Form2 I have a Button (Starter) and DataGridView. Also this button on click event calls database sql-query and generates records in DatagridView. DataGridView has four columns:

(Note: On columns [0] and [1] data are genereated from database, the columns [2] and [3] are template columns genereated at run-time also filled with data at run-time)

Now in Form2 when I double_click inside the Cell under the Qty In Stock column, a dialog-box pops up and allows me to enter the number in to that particular cell. Lets say Row-1: like so...

FoodName     FoodType     Qty In Stock     Status
-----------------------------------------------------------
Soup         Starter      10               Allways On Stock

Based on this: How can I take the value of that cell = 10 and dispalyit on the bottom-right corner of the Button (in this case button Soup). This is what the Soup Button should look like (in Form1): (Note: The Button called Soup is generated from database...)

##############
#   Soup     #
#         10 #
##############

Here is the code of dataGridView1_CellClick event (in Form2)...

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex == 2)
            {
                // Value is given in case the cell is empty
                string cellContent = "0";
                if (this.dataGridView1[e.ColumnIndex, e.RowIndex].Value != null)
                {
                    cellContent = this.dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString();
                }
                
                using (InputBox ib = new InputBox("Enter new stock amount:", this.dataGridView1[0, e.RowIndex].Value.ToString(), cellContent))
                {
                    if (ib.ShowDialog() == DialogResult.OK)
                    {
                        this.dataGridView1[e.ColumnIndex, e.RowIndex].Value = ib.Result;
                        cellContent = ib.Result;
                    }
                }
            }
        }

This is the code of InputBox dialog where it allows me to enter quantity in to the Cell of dataGridView1...

public partial class InputBox : Form
    {
        public InputBox(string text, string caption, string defaultValue)
        {
            //
            // The InitializeComponent() call is required for Windows Forms designer support.
            //
            InitializeComponent();

            this.Text = caption;  //.Clone().ToString();


            Size size;
            using (Graphics g = this.CreateGraphics())
            {
                Rectangle screen = Screen.PrimaryScreen.WorkingArea;
                SizeF sizeF = g.MeasureString(text, lblPrompt.Font, screen.Width - 20);
                size = sizeF.ToSize();
                size.Width += 4;
            }

            if (size.Width < 310)
            {
                size.Width = 310;
            }
            Size clientSize = this.ClientSize;
            clientSize.Width += size.Width - lblPrompt.Width;
            clientSize.Height += size.Height - lblPrompt.Height;
            this.ClientSize = clientSize;
            lblPrompt.Text = text;
            txtResult.Text = defaultValue;
            this.DialogResult = DialogResult.Cancel;
        }

        void CancelButtonClick(object sender, System.EventArgs e)
        {
            result = null;
            this.Close();
        }

        void AcceptButtonClick(object sender, System.EventArgs e)
        {
            this.DialogResult = DialogResult.OK;
            result = txtResult.Text;
            this.Close();
        }

        string result;

        public string Result
        {
            get
            {
                return result;
            }
        }

        private void btnSeven_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnSeven.Text + "7";
        }

        private void btnTwo_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnTwo.Text + "2";
        }

        private void btnOne_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnOne.Text + "1";
        }

        private void btnSix_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnSix.Text + "6";
        }

        private void btnFive_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnFive.Text + "5";
        }

        private void btnFour_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnFour.Text + "4";
        }

        private void btnNine_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnNine.Text + "9";
        }

        private void btnEight_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnEight.Text + "8";
        }

        private void btnThree_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnThree.Text + "3";
        }

        private void btnZero_Click(object sender, EventArgs e)
        {
            txtResult.Text += btnZero.Text + "0";
        }

        private void btnClear_Click(object sender, EventArgs e)
        {
            txtResult.Clear();
            txtResult.Focus();
        }
    }

This is the code how to create Buttons on Form1, and then take the database records and asign values to these buttons...

private void FoodAddButtons(DataTable table)
        {
            int xpos = 5;
            int ypos = 5;
            int space = 2;
            VistaButtonTest.VistaButton newButton = null;
            DtposMenuBS.Sort = "FoodPrice";
            try
            {
                foreach (DataRowView dr in DtposMenuBS.List)
                {
                    newButton = new VistaButtonTest.VistaButton();
                    newButton.ButtonText = dr["FoodName"].ToString();
                    newButton.AutoEllipsis = true;
                    newButton.Width = 152;
                    newButton.Height = 70;
                    newButton.CornerRadius = 4;
                    newButton.Font = new System.Drawing.Font("Arial Narrow", 15.00F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
                    newButton.BaseColor = System.Drawing.Color.FromArgb(((int)(((byte)(128)))), ((int)(((byte)(128)))), ((int)(((byte)(255)))));
                    newButton.ForeColor = System.Drawing.Color.Black;
                    newButton.HighlightColor = System.Drawing.Color.DarkGray;
                    newButton.GlowColor = System.Drawing.Color.DimGray;
                    if (xpos + newButton.Width > this.FoodMenuPanel.ClientSize.Width)
                    {
                        ypos += newButton.Height + space;
                        xpos = 5;
                    }
                    newButton.Location = new Point(xpos, ypos);
                    xpos += newButton.Width + space;
                    newButton.Click += ItemSelection1;
                    this.FoodMenuPanel.Controls.Add(newButton);
                }
            }
            finally
            {
                DtposMenuBS.Sort = "";
            }
        }

Reason for my vote of 1: Why cut and paste that lot? Why did you not just give a link to your Q&A question? Now, you have two places with the same info, that potentially could duplicate work if anyone does answer. D'Oh! | :doh:

Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

LAPEC wrote:

There could be a number of reasons for that:
1) No body knew the answer.
2) No body could be bothered to work out what the question was, because of the large lump of code they didn't want to bother with.
3) You didn't seem to have shown much effort in working on your problem yourself.
4) Some combination of the above.

You have to remember: not everybody looks at Q&A; nobody here gets paid for this; most of us have jobs which do pay and expect a certain amount of work from us.

You aren't helping yourself by taking a whining, petulant tone in your "bump" message...

Similar to this[^]?

That way you'd have an unusable drive that consumes power. How about disabling the entire drive?

I are Troll Suspicious | :suss:

I want to use code to open and close it, i don't want users to open it using the eject button.

And if your application hangs, user will have to restart the computer to open cd/dvd drive?

Don't forget to rate answer, that helped you. It will allow other people find their answers faster.

Or push a paper clip into the tiny hole!

The users do not need to use the cd/dvd drives during a certain period in my office,
I want a code to disabled the Eject button to keep them out, at this this time.
is there a such a code in c#, i found some in vb.
Thank for you response.

Users either have access, or they don't. You're looking for a "Child Safety Lock" for your employees? Smile | :)

I are Troll Suspicious | :suss:

Yes
can you help?

CD/DVD-Rom lockout? Why? What would prevent them from using a USB flash drive (or some other USB device) and using external files anyway? (I assume that is what you are trying to prevent.)

If you have the VB code, it should be fairly easy to translate...

...by someone who knows both VB and C#...

...me, not being one of those people.

Not a code example, but you can disable CDROM/Remoable Driver/etc. in Windows' Group Policy (at least in Windows 7)

Superglue.

Use a screwdriver to remove it.

Disconnect the wires.

As you see, lots of options available Smile | :)
