This tutorial will show you how to create data table without SQL server in ASP.NET 2.0 and C#. This is very useful for storing temporary data.
Add a GridView control, two lable controls, three textbox controls and button control in the page
Create datatable structure.
private DataTable CreateDataTable()
{
DataTable myDataTable = new DataTable();
DataColumn myDataColumn;
myDataColumn = new DataColumn();
myDataColumn.DataType = Type.GetType("System.String");
myDataColumn.ColumnName = "id";
myDataTable.Columns.Add(myDataColumn);
myDataColumn = new DataColumn();
myDataColumn.DataType = Type.GetType("System.String");
myDataColumn.ColumnName = "username";
myDataTable.Columns.Add(myDataColumn);
myDataColumn = new DataColumn();
myDataColumn.DataType = Type.GetType("System.String");
myDataColumn.ColumnName = "firstname";
myDataTable.Columns.Add(myDataColumn);
myDataColumn = new DataColumn();
myDataColumn.DataType = Type.GetType("System.String");
myDataColumn.ColumnName = "lastname";
myDataTable.Columns.Add(myDataColumn);
return myDataTable;
}

Yes, it is possible to find a good web host. Sometimes it takes a while. After trying several, we went with Server Intellect and have been very happy. They are the most professional, customer service friendly and technically knowledgeable host we've found so far.
Insert data into datatable.
private void AddDataToTable(string username,string firstname,string lastname,DataTable myTable)
{
DataRow row;
row = myTable.NewRow();
row["id"] = Guid.NewGuid().ToString();
row["username"] = username;
row["firstname"] = firstname;
row["lastname"] = lastname;
myTable.Rows.Add(row);
}

If you're ever in the market for some great Windows web hosting, try Server Intellect. We have been very pleased with their services and most importantly, technical support.
Add data to datatable which we have created
protected void btnAdd_Click(object sender, EventArgs e)
{
if (txtUserName.Text.Trim() == "")
{
this.lblTips.Text = "You must fill a username.";
return;
}
else
{
AddDataToTable(this.txtUserName.Text.Trim(), this.txtFirstName.Text.Trim(), this.txtLastName.Text.Trim(), (DataTable)Session["myDatatable"]);
this.GridView1.DataSource = ((DataTable)Session["myDatatable"]).DefaultView;
this.GridView1.DataBind();
this.txtFirstName.Text = "";
this.txtLastName.Text = "";
this.txtUserName.Text = "";
this.lblTips.Text = "";
} |
We migrated our web sites to Server Intellect over one weekend and the setup was so smooth that we were up and running right away. They assisted us with everything we needed to do for all of our applications. With Server Intellect's help, we were able to avoid any headaches!
Be noted "Session["myDatatable"] = myDt;" is important to ensure we can add new data continually until the page be closed.
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
myDt = new DataTable();
myDt = CreateDataTable();
Session["myDatatable"] = myDt;
this.GridView1.DataSource = ((DataTable)Session["myDatatable"]).DefaultView;
this.GridView1.DataBind();
