I want to fill my textboxes that these textboxes are in a one user control;
in my user control i have a tablelayout and in this tablelayout i put my textboxes ;
when i trace it ,ctr can find the tablelayout in usercontrol but i don't know how can i access to textboxes that exist in tablelayout?

this is my code:

foreach (Control ctr in mycomponent.Controls)
{
if (ctr is TextBox) // This is correct statement for checking if Object is specific type
{
TextBox tb = ctr as TextBox; // This line cast Object to TextBox
tb.Text = "salam"; //dataSet1.DataTable1[nCount].Text1;
nCount++;
}
}

As Groub box, Panel or Table Layout, it is a Countainer. It can hold Other Controls.

foreach (Control ctr in mycomponent.Controls)
{
   if (ctr is TableLayoutPanel) // This is correct statement for checking if Object is specific type
   {
      TableLayoutPanel tp = ctr as TableLayoutPanel;
      foreach (Control ctrtp in tp.Controls)
      {
         if (ctrtp is TextBox)
         {
            TextBox tb = ctr as TextBox; // This line cast Object to TextBox
            tb.Text = "salam"; //dataSet1.DataTable1[nCount].Text1;
         }
      }
   }
}

Use SqlDataReader [^]to bind textboxes with value from table.

If you do not want to type for each control you can get all controls from Form

foreach (Control ctr in this.Controls)
{
if (ctr is TextBox)
{
// To do
TextBox tb = ctr as TextBox;
}
}

Edit: Corrected Code

Is it possible for you that how can i bind each textboxes to each cells of datatable after i write this foreach?

How do you access your data?
Are you using DataSet or do you create a reader through code?

Those 80 cells, are in Single Row?

I have 7 datatable that these datatables are the result of 7 select from database;
The total culumns of these datatables are 80.

I will suggest you to set column alias name same as textboxes names and bind each TextBox (by looping) with value from correspoding coumn name.

Control have a Name property

farokhian wrote:

Look at example at my other reply, you go through all Controls on form, not only TextBoxs

how can i access the cells of each datatable to set each textbox?
Depends. Are you using DataSet?
