Actually i'm creating web template using and c#.
in my user control page i have to create the table dynamically. i just read the data from XML file then retrieve the name and number of columns and rows of each table. while i'm creating the table i assign the name and id to each cell. because i have one row including some textbox for adding the data to database. but after i have created the table i can not access to the textbox cells based on id to get their data and insert it to database. my dynamic table code is:

public void CreateAddDynamicTable()
    XmlDocument xDocRead = new XmlDocument();
    string xModuleName = hid_ChooseModule.Value;
    XmlNode xColCounter = xDocRead.SelectSingleNode("ModuleTemp/" + xModuleName + "/List");
    int colCount = xColCounter.ChildNodes.Count;

    int nonPkCounter = 0;
    string[] nonPrimaryKey = new string[100];
    string[] nonPkNewDataTemp = new string[100];

    for (int i = 1; i <= colCount; i++)
        if (xDocRead.SelectSingleNode("ModuleTemp/" + xModuleName + "/Add/TableColumn" + i).Attributes.GetNamedItem("IsPrimaryKey").Value == "N")
            nonPrimaryKey[nonPkCounter] = xDocRead.SelectSingleNode("ModuleTemp/" + xModuleName + "/Add/TableColumn" + i).Attributes.GetNamedItem("Name").Value;


    // Fetch the number of Rows and Columns for the table 
    // using the properties
    int tblRows = nonPkCounter;
    int tblCols = 2;

    // Create a Table and set its properties 
    Table tbl = new Table();
    // Add the table to the placeholder control
    // Now iterate through the table and add your controls 
    for (int i = 0; i < tblRows; i++)
        TableRow tr = new TableRow();
        for (int j = 0; j < tblCols; j++)
            TableCell tc = new TableCell();
            Label td_Add_Header = new Label();
            TextBox td_Add = new TextBox();

            if (j == 0)
                td_Add_Header.Text = nonPrimaryKey[i];
                td_Add_Header.ID = "lb" + (i + 1) + "_header_AddModule";

                // Add the control to the TableCell
                tc.CssClass = "td_Header_AddModule";
                td_Add.Text = "";
                td_Add.ID = "tb" + (i + 1) + "_AddModule";
                // Add the control to the TableCell
                tc.CssClass = "td_Tb_AddModule";

            // Add the TableCell to the TableRow
        // Add the TableRow to the Table

my user control page which is contain a PlaceHolder is as below:

<asp:Panel ID="pn_Uc_TModule" runat="server">

<asp:Table runat="server" ID="table_Uc_TModule" CssClass="table_Uc_TModule" Width="100%">
 <asp:TableRow runat="server" VerticalAlign="Top" Height="50px">
                <asp:TableCell runat="server">
                    <asp:Button runat="server" Text="" CssClass="btn_Add_Active" OnClick="btn_AddNew_Click" />
                    <asp:Button ID="btn_Cancel_NewItem" runat="server" Text="" CssClass="btn_Cancel_New" OnClick="btn_Cancel_AddNew" Visible="false" />

                    <asp:Table runat="server" ID="table_Uc_AddModule" Visible="false">
                        <asp:TableRow runat="server">
                            <asp:TableCell runat="server" >

                                <asp:PlaceHolder ID="ph_Uc_AddModule" runat="server">

                        <asp:TableRow ID="TableRow1" runat="server">
                            <asp:TableCell runat="server" CssClass="td_Tb_AddModule" HorizontalAlign="Center">
                                <asp:Button ID="btn_Insert" runat="server" OnClick="Uc_AddModule_ItemInsert" Text="" CssClass="btn_Add" />
                                <asp:Button ID="btn_Cancel" runat="server" OnClick="Uc_AddModule_Clear" Text="" CssClass="btn_Clear" />


i'm using below method in my insert function at the code behind to access the data inserted at the textbox:

for (int i = 1; i <= nonPkCounter; i++)
        TextBox textBox = (ph_Uc_AddModule.FindControl("tb" + i + "_AddModule")) as TextBox;
        nonPkNewDataTemp[i] = textBox.Text;

i have tried pn_Uc_TModule.FindControl("tb" + i + "_AddModule") and also This.ph_Uc_AddModule.FindControl("tb" + i + "_AddModule") but still con not get the texbox data to insert it to database. could you please guide me how to get it done.
appreciate your consideration.

You should have to create public properties in User control.

For instance,

public String Name
  get{ return txtName.Text;}
  set { txtName=value;}

thanks for the reply.
