User-1305878657 posted

Hi Team,

I am creating textboxes dynamically from the code behind C#.but problem is that in one save button i have to access these textboxes value for save into database.

   DataTable dt = new DataTable();

   dt = ObjUserFn.FnGetMIS_MasterSap_DATA("select (select elementname from QCElement where ElementID=qel.ElementID) TestResult,'' ElementValue,qel.MatrlID from QCElementLookup qel where qel.MatrlID='" + cboMatrlName.Value.ToString() + "'");

            if (dt.Rows.Count > 0)
            {
                Panel2.Controls.Clear();
                //Adding in tablular format
                int rowCount = dt.Rows.Count;
                int columnCount = Convert.ToInt32("1");
                Table table = new Table();
                table.ID = "table1";
                for (int i = 0; i < rowCount; i++)
                {
                    TableRow row = new TableRow();
                    for (int j = 0; j < columnCount; j++)
                    {
                        TableCell cell1 = new TableCell();
                        TableCell cell2 = new TableCell();
                        TextBox TxtBoxU = new TextBox();
                        Label lblU = new Label();
                       TxtBoxU.ID = "txt" + dt.Rows[i][0].ToString();
                        lblU.Text = dt.Rows[i][0].ToString();
                        cell1.Controls.Add(lblU);
                        cell2.Controls.Add(TxtBoxU);
                        row.Cells.Add(cell1);
                        row.Cells.Add(cell2);
                    }
                    table.Rows.Add(row);
                }
                Panel2.Controls.Add(table);
            }

Hi mohan,

How to access these textboxes value in save button click.......

When the Get Button is clicked, a loop is executed over all the TextBoxes present inside the Panel control.

HTML Markup

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

</asp:Panel>

<asp:Button ID="btnGet" runat="server" Text="Get Values" OnClick="GetTextBoxValues" />

Getting values of dynamically created TextBoxes

protected void GetTextBoxValues(object sender, EventArgs e)
{
    string value = "";
    foreach (TextBox textBox in pnlTextBoxes.Controls.OfType<TextBox>())
    {
        value += textBox.Text + "\\n";
    }
}

Thank u for reply i already tried this earlier but then also i not getting those textboxes values then i put this post.....

        string value = "";
        foreach (TextBox textBox in Panel2.Controls.OfType<TextBox>())
        {
            value += textBox.Text + "\\n";
        }

Basically this part is not working in foreach loop Panel2.Controls.OfType<TextBox>()

Hi mohan,

Based on your code, you should add

Panel2.Controls.Add(TxtBoxU);

Hi mohan,

i am finally adding table into panel not each control

Take a look at the following sample.

protected void Page_Load(object sender, EventArgs e)
{           
    BindData();
}

protected void btnGet_Click(object sender, EventArgs e)
{
    string value = "";
    foreach (TextBox textBox in Panel2.Controls.OfType<TextBox>())
    {
        value += textBox.Text + "\\n";
    }
}

private void BindData()
        {
            Panel2.Controls.Clear();
            DataTable dt = new DataTable();

            dt.Columns.AddRange(new DataColumn[3] { new DataColumn("TestResult", typeof(string)),

                            new DataColumn("ElementValue", typeof(string)),

                            new DataColumn("MatrlID",typeof(string)) });

            dt.Rows.Add("1", "TestA", "A");
            dt.Rows.Add("2", "TestB", "B");
            dt.Rows.Add("3", "TestB", "C");
            dt.Rows.Add("4", "TestB", "D");

            if (dt.Rows.Count > 0)
            {
                Panel2.Controls.Clear();
                //Adding in tablular format
                int rowCount = dt.Rows.Count;
                int columnCount = Convert.ToInt32("1");
                Table table = new Table();
                table.ID = "table1";


                List<TextBox> t = new List<TextBox>();
                for (int i = 0; i < rowCount; i++)
                {

                    TableCell cell1 = new TableCell();
                    TableCell cell2 = new TableCell();
                    TextBox TxtBoxU = new TextBox();
                    Label lblU = new Label();
                    TxtBoxU.ID = "txt" + dt.Rows[i][0].ToString();
                    lblU.Text = dt.Rows[i][0].ToString();
                    cell1.Controls.Add(lblU);
                    cell2.Controls.Add(TxtBoxU);


                    Literal lt = new Literal();
                    lt.Text = "<br />";

                    Panel2.Controls.Add(lblU);
                    Panel2.Controls.Add(TxtBoxU);
                    Panel2.Controls.Add(lt);
                }

            }
        }

    <form id="form1" runat="server">
    <div>
        <asp:Panel ID="Panel2" runat="server"></asp:Panel>
        <asp:Button ID="btnGet" runat="server" Text="Button" OnClick="btnGet_Click" />
