Need to Find CheckBox Controls in asp:Table

Asked by CJSantora in Programming for ASP.NET, C# Programming Language, Microsoft Visual C#.Net

Tags:

Hi Experts, we have an application taht uses a asp:Table as a object to hold Checkboxes, which are created dynamically at runtime. So the user is populating a database and the records are used to create the checkboxes and build a form. this all works well so far.

However upon submitting the form, I need to reference the check boxes to see which are selected. And I am having difficulty with this. I cannot seem to find the checkboxes. I am attaching some of the code and would appreciate any help that can be offered.

Thank you in advanceStart Free Trial

Building of checkboxes:
int cnt = 0;
            foreach (DataRowView dr in dv)
            {
 
                if ((cnt % 3) == 0)
                {
                    row = new TableRow();
                    cell = new TableCell();
                    cell.ID = "Cell" + cnt.ToString();
                    cell.CssClass = "style2";
 
                    CheckBox chk = new CheckBox();
                    chk.ID = "chk" + dr["Name"].ToString().Replace(" ", "");
                    chk.Text = dr["Name"].ToString();
                    cell.Controls.Add(chk);
 
                    row.Cells.Add(cell);
                }
                else
                {
                    cell = new TableCell();
                    cell.ID = "Cell" + cnt.ToString();
 
                    CheckBox chk = new CheckBox();
                    chk.ID = "chk" + dr["Name"].ToString().Replace(" ", "");
                    chk.Text = dr["Name"].ToString();
                    cell.Controls.Add(chk);
 
                    row.Cells.Add(cell);
                }
 
                if ((cnt % 3) == 0)
                    tblCategories.Rows.Add(row);
 
                cnt++;
            }
 
Trying to find checkboxes: // this is the Problem
 
            foreach (TableRow row in tblParentCategories.Rows)
            {
                Control ctl = new Control();
                ctl = (Control)row.FindControl();
                if (ctl.GetType() == typeof(CheckBox))
                    if (chk.Checked == true)
                    {
                        chk.Text = (ctl as CheckBox).Text;
                        CategoryName = chk.Text;
                    }
            }
