How to dynamically Create huge grid of editable textboxes at runtime..Help..

• Ljungstedt

  So instead of puting my TSV file data into a 1 dimensional array I should put into a 2 dimensional arrary . That way when I bind my data grid to my arrary it will work b/c data grids are like 2D. Ill try out that code as soon as I get a chance. If not later today, I can do it at work tommorow.

  You guys are great, I'm learning alot from here.

  hi,

  yes you can write it back to textfile or you can write it to xml file which will be easier because you will write less code like mydataset.readxml("myflile.xml") but in the text form you have to provide a pattern for that

  the best way to do with your data is to put a datasource in your form and to make it between your datagridview and your datatable it will update the values itself for you because reaching to a particular cell in datagridview is a little bit silly you have to get it by its coordinate like column number and row number something like this

  this.MyDataGridView.Rows[0].Cells[0].Selected = false;

  so add a dataset , and binding source to you form designer

  after the creation of your table add it to your dataset

  mydataset.tables.add(mytable)

  relate you datasource to the database

  mybindingsource.datasource = mydataset

  mybindingsource.datamemeber = "mytablename"

  binding your datagridview to your datasource

  mydatagridview.datasource = mybidingsource

  now every change you gonna made is saved back to your table b4 you exist your program chose the way you want to save it xml of text

  That code works beautifully shakalama. It looks more professional too. I like to sort feature. I was able to load my TSV file into the datagrid.

  I'm just worried about one thing. The data that will be stored in this datagrid comes from a TSV file. But I wanted to be able to update the data from another source if needed.

  It seemed pretty easy if I had a textbox grid because, every textbox had its own name so I can easily update any paticular textbox field in the grid. How can I do this with the datagrid

  say if I wanted to update a field in this location row 5, column 7 or row 8, column 9. Can this be done, I would think the sort feature would change these locations each time I sorted it, so should I disable the sort feature to achieve this

  Thanks again....

  Hi!

  Why not use DataGridView and dynamically construct columns

  My application calls for many textboxes due to the interface.  How do i get textboxes to point to a specific database value.  I am using vb2005.

  hi,

  i guess the best thing to do is to use the datagridview instead of creating all those textbox something like that

  public partial class Form1 : Form

  {

  public Form1()

  {

  InitializeComponent();

  }

  private void Form1_Load(object sender, EventArgs e)

  {

  string [,] mystring = new string[2,2];

  mystring[0,0] = "haitham";

  mystring[0,1] = "nabil";

  mystring[1,0] = "ehab";

  mystring[1,1] = "lotfy";

  //creat a table to store the values in it

  DataTable name = new DataTable("name");

  name.Columns.Add("personal");

  name.Columns.Add("parents");

  for (int row = 0; row < mystring.GetLength(1); row++)

  {

  //looping through my array geting hte value storeing it

  //into my table

  DataRow dr = name.NewRow();

  dr["personal"] = mystring[row,0];

  dr["parents"] = mystring[row, 1];

  name.Rows.Add(dr);

  }

  //binding my data to datagridview

  dataGridView1.DataSource = name;

  dataGridView1.ReadOnly = true;

  }

  if you are insist to use the textboxs you can use this but you have to make sure of your form height property

  //general variables

  private string[] myname ={ "haitham", "nabile", "Mohamed", "salem", "ismael", "khatab", "ali", "ibrahim"};

  private Point textboxlocation = new Point(10, 10);

   

  private void Form2_Load(object sender, EventArgs e)

  {

  for (int i = 0 ; i < myname.Length; i++)

  {

  TextBox mytextbox = new TextBox() ;

  mytextbox.Name = "txtbx" + i;

  mytextbox.Text = myname [ i ];

  mytextbox.Location = new Point(textboxlocation.X , textboxlocation.Y);

  textboxlocation.Y += +mytextbox.Height + 5;

  Controls.Add(mytextbox);

  }

  hope that helps

  I agree with Sergey, your life would be much easier if you used a DataGrid... if you absolutely must use TextBoxes though... in code, create an array of TextBoxes and populate it not unlike this...

              for (int x = 0; x < DesiredNumberOfTextBoxes; x++)
              {
                  textBoxes[x] = new TextBox();
                  textBoxes[x].Location = //Set desired location
                  textBoxes[x].Size = //Set desired size
                  Controls.Add(textBoxes[x]); //Add TextBox to parent container
              }

  Only a bit bigger and probably using a two dimensional array and more advanced math for positioning.

  But if you can - don't use so many text boxes. They all will require underlying Windows EDIT control, they all eat a lot of system resources! And up/down navigation will not work natively...

  Why didn't I think of that.. maybe its because I've never used one before......learn something everything. Ill give it a shot....as long as the end user will be able to edit the values inside the datagrid...this should work perfectly.

  Thanks alot for your help. Im new to this forum and I'm rather surprised at how fast I got an answer. Appreciate it.

  no , this was a part from something i was doing here and my example was 2 D array you can make it 1D, but i wasn't able to bind it to the datagrid directly(regardless 1D or 2D) so i created a table from it first then i bound the table tomy datagridview

  if you are aray is 1D thats fine go with it , its its 2 or three you can do it depending on how many column you want to see in your datagridview

  hope that helps
