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:
http://weblogs.asp.net/scottgu/archive/2007/12/14/new-asp-net-dynamic-data-support.aspx
http://msdn.microsoft.com/en-us/magazine/gg535665.aspx
http://www.asp.net/web-forms/videos/aspnet-dynamic-data/getting-started-with-dynamic-data
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("<br/>");
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.
