[RESOLVED] Dynamic FormView

Hello,

Is it possible to add a dynamic formview to a placeholder, with edititemtemplate, insertitemtemplate, and itemtemplate's created dynamically? and I wanted to load the data into that form view from a datatable, if possible? If so does anyone have a simple
example. I've been searching the web and haven't found anything good, everythign that i have found, has been extremely complicated and not what i was looking for.

Any help is very much appreciated.

Please have a look at ASP.NET Dynamic Data Website feature:

Thank you very much for your links, but that is alot more advanced than i expected, i'm looking for something a little bit simpler.

I am trying to figure it out,  and have came up with the following code:

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class test3 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        DataTable table = GetTable();
        FormView frm = new FormView();
        frm.ID = "FormView1";
        frm.DataSource = table;
        frm.DataBind();
        DynamicControlsHolder1.Controls.Add(frm);
    }

    static DataTable GetTable()
    {
        //
        // Here we create a DataTable with four columns.
        //
        DataTable table = new DataTable();
        table.Columns.Add("Dosage", typeof(int));
        table.Columns.Add("Drug", typeof(string));
        table.Columns.Add("Patient", typeof(string));
        table.Columns.Add("Date", typeof(DateTime));

        //
        // Here we add five DataRows.
        //
        table.Rows.Add(25, "Indocin", "David", DateTime.Now);
        table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);
        table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);
        table.Rows.Add(21, "Combivent", "Janet", DateTime.Now);
        table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);
        return table;
    }


}

But for some reason, it doesn't dislpay anything. Can someone please help me with this?

Hi,

From what I understand you are having difficulty with generating FormView dynamically. According to your code, I find you have not created
ItemTemplate for FormView, that’s why your FormView not shown.

I have created a sample, please try to refer to the following code:

using System;

using System.Collections.Generic;

using System.Data;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

 

namespace DynamicFormViewWeb

{

    public sealed class GenerTemplate : ITemplate

    {

        void ITemplate.InstantiateIn(Control container)

        {

            Label DosageLabel = new Label();

            DosageLabel.ID = "Dosage";

            DosageLabel.DataBinding += new EventHandler(DosageLabel_DataBinding);

             LiteralControl lineBreak = new LiteralControl("
");

             Label DrugLabel = new Label();

             DrugLabel.ID = "Drug";

             DrugLabel.DataBinding += new EventHandler(DrugLabel_DataBinding);

             Label PatientLabel = new Label();

             PatientLabel.ID = "Patient";

             PatientLabel.DataBinding += new EventHandler(PatientLabel_DataBinding);

             Label DateLabel = new Label();

             DateLabel.ID = "Date";

             DateLabel.DataBinding += new EventHandler(DateLabel_DataBinding);

             //System.Web.UI.WebControls.LinkButton myBtn = new LinkButton();

             //myBtn.Text = "dd";

             //myBtn.ID = "Edit";

             //myBtn.CommandName = "Edit";

             container.Controls.Add(DosageLabel);

             container.Controls.Add(lineBreak);

             container.Controls.Add(DrugLabel);

             container.Controls.Add(lineBreak);

             container.Controls.Add(PatientLabel);

             container.Controls.Add(lineBreak);

             container.Controls.Add(DateLabel);

             //container.Controls.Add(myBtn);

         }

        private void DosageLabel_DataBinding(Object sender, EventArgs e)

        {

            Label DosageLabelControl = (Label)sender;

            FormView formViewContainer = (FormView)DosageLabelControl.NamingContainer;

            DataRowView rowView = (DataRowView)formViewContainer.DataItem;

            DosageLabelControl.Text = rowView["Dosage"].ToString();

        }

        private void DrugLabel_DataBinding(Object sender, EventArgs e)

        {

            Label DrugLabelControl = (Label)sender;

            FormView formViewContainer = (FormView)DrugLabelControl.NamingContainer;

            DataRowView rowView = (DataRowView)formViewContainer.DataItem;

            DrugLabelControl.Text = rowView["Drug"].ToString();

        }

        private void PatientLabel_DataBinding(Object sender, EventArgs e)

        {

            Label PatientLabelControl = (Label)sender;

            FormView formViewContainer = (FormView)PatientLabelControl.NamingContainer;

            DataRowView rowView = (DataRowView)formViewContainer.DataItem;

            PatientLabelControl.Text = rowView["Patient"].ToString();

        }

        private void DateLabel_DataBinding(Object sender, EventArgs e)

        {

            Label DateLabelControl = (Label)sender;

            FormView formViewContainer = (FormView)DateLabelControl.NamingContainer;

            DataRowView rowView = (DataRowView)formViewContainer.DataItem;

            DateLabelControl.Text = rowView["Date"].ToString();

        }

    }

    public partial class WebForm1 : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

            DataTable table = GetTable();

            FormView frm = new FormView();

            frm.ID = "FormView2";

            frm.ItemTemplate = new GenerTemplate();

            frm.DataSource = table;

            frm.DataBind();

            form1.Controls.Add(frm);

        }

 

        static DataTable GetTable()

        {

            //

            // Here we create a DataTable with four columns.

            //

            DataTable table = new DataTable();

            table.Columns.Add("Dosage", typeof(int));

            table.Columns.Add("Drug", typeof(string));

            table.Columns.Add("Patient", typeof(string));

            table.Columns.Add("Date", typeof(DateTime));

 

            //

            // Here we add five DataRows.

            //

            table.Rows.Add(25, "Indocin", "David", DateTime.Now);

            table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);

            table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);

            table.Rows.Add(21, "Combivent", "Janet", DateTime.Now);

            table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);

            return table;

        }

    }

}

Hope it can help you, if you have any question, please let me know.
