Dynamic Creation of Controls

Output:

Firstly add a panel control ,a textbox and a button to design page .when we enter a number in textbox at run time ,the same number controls are created at runtime.

Source Code:

protected void btninsert_Click(object sender, EventArgs e)
{
int count =Convert.ToInt32(TextBox1.Text);
Panel1.Controls.Clear();
Table tb = new Table();
tb.GridLines = GridLines.Both;
for (int i = 0; i < count; i++)
{

TableCell c1 = new TableCell();
TableRow rw = new TableRow();
TextBox tx = new TextBox();
c1.Controls.Add(tx);
rw.Cells.Add(c1);
tb.Rows.Add(rw);
}
Panel1.Controls.Add(tb);
}

Paging Advantage of Datalist Control in asp.net with c#

HTML Coding :

Server Side Coding: c#

SqlConnection scn = new SqlConnection("Data Source=.;Initial Catalog=iptv_database;Integrated Security=True");
int Start;
protected void Page_Load(object sender, EventArgs e)
{

if (!Page.IsPostBack)
{
ViewState["Start"] = 0;
BindData();
}
}
void BindData()
{

SqlDataAdapter da = new SqlDataAdapter("select * from addprogram", scn);
DataSet ds= new DataSet();
Start = (int)ViewState["Start"];
ViewState["Size"] = 2;
da.Fill(ds,Start,(int)ViewState["Size"], "addprogram");
DataList1.DataSource = ds;
DataList1.DataBind();

}
protected void lnkPrevious_Click(object sender, EventArgs e)
{
Start = (int)ViewState["Start"] - (int)ViewState["Size"];
ViewState["Start"] = Start;
if (Start <= 0)
{
ViewState["Start"] = 0;
}
BindData();
}
protected void lnkNext_Click(object sender, EventArgs e)
{
int count = DataList1.Items.Count;
Start = (int)ViewState["Start"] + (int)ViewState["Size"];
ViewState["Start"] = Start;
if (count <(int)ViewState["Size"])
{
ViewState["Start"] = (int)ViewState["Start"] + (int)ViewState["Size"];
Start = (int)ViewState["Start"];

Creating Controls at Runtime

TextBox txt1 = new TextBox();
TextBox txt2 = new TextBox();
txt1.Text = "This is the textbox inside the placeholder";
txt2.Text = "This is the textbox inside the panel";
txt1.Style["width"] = "250px";
txt2.Style["width"] = "250px";
PlaceHolder1.Controls.Add(txt1);
Panel1.Controls.Add(txt2);

RSS Feeds in asp.net with c#

A simple Program to view xml in Datagrid

using System.Xml;

XmlTextReader reader = new XmlTextReader("http://msdn.microsoft.com/rss.xml");

// creates a new instance of DataSet

DataSet ds = new DataSet();

// Reads the xml into the dataset

ds.ReadXml(reader);

// Assigns the data table to the datagrid

myDataGrid.DataSource = ds.Tables[2];

// Binds the datagrid

myDataGrid.DataBind();
