HOw can I handle Dynamically generated Controls - asp.net

Question

In the following image the table displayed is generated dynamically on click of “Create Table” button.
I have added textboxes, fileupload, Buttons dynamically to the table.
I want to upload files from fileupload control on click of “Upload” button in the Table, but I have no idea how to handle those Dynamically generated Controls.
Code of “Create Table” button goes like this :
protected void Button1_Click(object sender, EventArgs e)
{
//Button1.Visible = false;
//Creat the Table and Add it to the Page
Table table = new Table();
table.Caption = "Table1";
table.BackColor = System.Drawing.Color.BurlyWood;
Page.Form.Controls.Add(table);
for (int i = 0; i < 3; i++)
{
TableRow row = new TableRow();
row.BorderStyle = BorderStyle.Ridge;
for (int j = 0; j <= 10; j++)
{
TableCell cell = new TableCell();
cell.BorderWidth = 5;
cell.BorderStyle = BorderStyle.Ridge;
cell.BorderColor = System.Drawing.Color.Azure;
for (j = 0; j <= 0; j++)
{
Label lbl = new Label();
lbl.ID = "lblCCRow" + i + "Col" + j;
lbl.Text = "CC NO. " + i + " ";
lbl.Width = 100;
// Add the control to the TableCell
cell.Controls.Add(lbl);
}
for (j = 1; j <= 1; j++)
{
Label lbl = new Label();
lbl.ID = "lblRow" + i + "Col" + j;
lbl.Width = 100;
lbl.Text = Convert.ToString(DateTime.Now.Day) + "/" + Convert.ToString(DateTime.Now.Month) + "/" + Convert.ToString(DateTime.Now.Year);
// Add the control to the TableCell
cell.Controls.Add(lbl);
}
for (j = 2; j <= 7; j++)
{
TextBox tb = new TextBox();
tb.Width = 100;
tb.ID = "txtBoxRow" + i + "Col" + j;
tb.Text = "";
// Add the control to the TableCell
cell.Controls.Add(tb);
}
for (j = 8; j <= 8; j++)
{
FileUpload fileUp = new FileUpload();
fileUp.ID = "flupRow" + i + "Col" + j;
fileUp.Width = 220;
cell.Controls.Add(fileUp);
}
for (j = 9; j <= 9; j++)
{
Button btnUpld = new Button();
btnUpld.Width = 100;
btnUpld.ID = "btnUpRow" + i + "Col" + j;
btnUpld.Text = "Upload";
cell.Controls.Add(btnUpld);
}
for (j = 10; j <= 10; j++)
{
Label lbl = new Label();
lbl.ID = "lblRow" + i + "Col" + j;
lbl.Text = "[ Status ]";
lbl.Width = 100;
// Add the control to the TableCell
cell.Controls.Add(lbl);
}
row.Cells.Add(cell);
}
// Add the TableRow to the Table
table.Rows.Add(row);
}
//table.Rows.Add(row);
}

Answer 1

Attach event handeler btnUpld runtime.
Button btnUpld = new Button();
btnUpld.Width = 100;
btnUpld.ID = "btnUpRow" + i + "Col" + j;
btnUpld.Text = "Upload";
btnUpld.Click += new EventHandler(btnUpld_Click);
cell.Controls.Add(btnUpld);
//code behind
private void btnUpld_Click(object sender, System.EventArgs e)
{
// Add upload functionality here
}

Answer 2

btnUpload.Click +=new EventHandler(btnUpload_Click);
add an event handler after adding the control dynamically to the form, using the above code and then add create a function that handles this event using the following code
protected void btnEdit_Click(object sender, EventArgs e)
{
}
