Dynamic Controls and EventHandlers

[stimp80]

I'm working on a Windows Form Application in Visual Studio 2010.

I have a Database that I am using to pull data to dynamically create checkboxes inside a loop. In between each of these, I'm creating a child loop to create more checkboxes from a sorted DataSet. At the end of each of the internal loops, I'm creating a TextBox and a Button to bring up a new form which requires 2 parameters. It needs to get a current value of a variable set on the parent loop, and the current text of the TextBox.

This is the code for the loops:

int count = (int)CategoryTableAdapter.ScalarQuery();
            int c = 1; // textbox name increment
            int x = 1; //  category checkbox name increment
            int y = 50; // point
            int z = 50; // point
            int tabCount = 1;
            //
            // New Loop to Create New CheckBox for each Category
            //
            for (int i = 0; i < count; i++)
            {
                string categoryName = 
                Convert.ToString(this._projectmanager_dbDataSet.category.Rows[i]["name"]);
                Int64 categoryId = 
                Convert.ToInt64(this._projectmanager_dbDataSet.category.Rows[i]["id"]);
                CheckBox checkBox1 = new System.Windows.Forms.CheckBox();
                this.panel2.Controls.Add(checkBox1);
                checkBox1.AutoSize = true;
                checkBox1.Location = new System.Drawing.Point(y,z);
                checkBox1.Name = "categoryCheckBox" + x;
                x++;
                checkBox1.Size = new System.Drawing.Size(80, 17);
                checkBox1.TabIndex = tabCount;
                checkBox1.Text = categoryName;
                checkBox1.UseVisualStyleBackColor = true;
                z = (z + 20);
                tabCount++;
                if (checkBox1.Checked == true)
                {
                    int count2 = (int)ActivityTableAdapter.ScalarQuery(categoryId);
                    y = (y + 30);
                    // Create sorted DataTable from activity with correct Catery ID
                    DataTable sortedActivityDataTable = 
                    _projectmanager_dbDataSet.activity.Clone();
                    string strExpr = ("category_id == " + categoryId);
                    string strSort = "name ASC";
                    DataRow[] results = 
                    _projectmanager_dbDataSet.activity.Select(strExpr, strSort);
                    foreach (DataRow dr in results)
                    sortedActivityDataTable.ImportRow(dr);
                    DataRow[] foundrows = 
                    _projectmanager_dbDataSet.activity.Select(strExpr, strSort);
                    // Loop to create Activity CheckBoxes for each Activity for a Category
                    for (int e = 0; e < count2; e++)
                    {
                        string activityName = sortedActivityDataTable.Rows[e]["name"].ToString();
                        string activityIdA = sortedActivityDataTable.Rows[e]["id"].ToString();
                        Int64 activityId = Convert.ToInt64(activityIdA);
                        CheckBox checkbox1 = new System.Windows.Forms.CheckBox();
                        this.panel2.Controls.Add(checkbox1);
                        checkbox1.AutoSize = true;
                        checkbox1.Location = new System.Drawing.Point(y, z);
                        checkbox1.Name = "activityCheckBox" + d;
                        d++;
                        checkbox1.Size = new System.Drawing.Size(80, 17);
                        checkbox1.TabIndex = tabCount;
                        checkbox1.Text = activityName;
                        checkBox1.UseVisualStyleBackColor = true;
                        z = (z + 20);
                        tabCount++;
                    }
                    y = (y - 30);
                    //
                    //Creat A TextBox to add a New activity During Each category
                    //
                    TextBox newActivityTextBox = new System.Windows.Forms.TextBox();
                    newActivityTextBox.Location = new System.Drawing.Point(y, z);
                    newActivityTextBox.Name = ("newActivityTextBox" + i);
                    c++;
                    newActivityTextBox.RightToLeft = System.Windows.Forms.RightToLeft.No;
                    newActivityTextBox.Size = new System.Drawing.Size(250, 20);
                    newActivityTextBox.TabIndex = tabCount;
                    newActivityTextBox.Text = "<New Category>";
                    this.panel2.Controls.Add(newActivityTextBox);
                    tabCount++;
                    //
                    // New Activity Button
                    //
                    Button newActivityButton = new System.Windows.Forms.Button();
                    panel2.Controls.Add(newActivityButton);
                    newActivityButton.Location = new System.Drawing.Point((y + 275), (z - 1));
                    newActivityButton.Name = ("newActivityButton" + i);
                    newActivityButton.Size = new System.Drawing.Size(75, 23);
                    newActivityButton.TabIndex = 8;
                    newActivityButton.Text = "Add Activity";
                    newActivityButton.UseVisualStyleBackColor = true;
                    newActivityButton.Click += new System.EventHandler(newActivityButton_Click);
                    z = (z + 20);
                }
            }

And here is the basic code for the eventhandler:

public void newActivityButton_Click(object sender, EventArgs e)
        {
            this.categoryTableAdapter.Fill(this._projectmanager_dbDataSet.category);
            NewActivityForm1 frm = new NewActivityForm1(newActivityTextBox.Text, categoryId);
            frm.Show();
        }

This however, doesn't even recognize the the newActivityTextBox or the variable "CategoryId" (created on line 12). What I need to accomplish is to not only have it recognize these values, but pull the correct values for them at the time that the dynamic controls are created.
