The name 'GetData(cmd)' does not exist in the current context - c#

I have this error "The name 'GetData' does not exist in the current context". I had tried to declare the getdata() function but it still got error.
public partial class v2_kradescription : System.Web.UI.Page

my c# code behind already has

How to use Entity Framework to upload data?

I have this web written in C# , that provides a table for user with these data ( ID , FROM , TITLE , MESSAGE ) Table name on database is MessagesTable
My question is how can I use Entity Framework to upload data on the table , I used to do it using ConnectionStrings.
public partial class UsersEF : System.Web.UI.Page
{
static string ConnStr = ConfigurationManager.ConnectionStrings["dbconnection"].ConnectionString;
int SelectedID = 0;

cmd.Parameters.Add(new SqlParameter("#id",SqlDbType.Int)).Value=SelectedID;

}
else {

};
}

}

You can update it this way using EF -
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
SelectedID = int.Parse(e.NewValues["Id"].ToString());
// retrieve from db
var messages = this.context.MessagesTable.FirstOrDefault(x=>x.id == SelectedID);
// update values
messages.From = int.Parse(e.NewValues["From"].ToString());
messages.To= int.Parse(e.NewValues["To"].ToString());
messages.Title = int.Parse(e.NewValues["Title"].ToString());
messages.Message= int.Parse(e.NewValues["Message"].ToString());
//Save changes into db
this.context.MessagesTable.Update(messages);
this.context.SaveChanges();
}

Unable to update record in textbox in C#

How to Put two DataValueFields?

How do I bind a product name, then get a product id and price in the label result? The three attributes are from the same table in DB.
Code:
public partial class CreateOrder : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false) bindListBox();
}
}
private void bindListBox()
{
ddlProduct.DataSource = getReader();
ddlProduct.DataTextField = "productName";
ddlProduct.DataValueField = "IDANDPRICE";
ddlProduct.DataBind();
}
private SqlDataReader getReader()
{
//get connection string from web.config
string strConnectionString =
ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
SqlConnection myConnect = new SqlConnection(strConnectionString);
string strCommandText = "SELECT productName, productID,productPrice,(productID + '-' + productPrice) AS IDANDPRICE from Product";
SqlCommand cmd = new SqlCommand(strCommandText, myConnect);
myConnect.Open();
SqlDataReader reader = cmd.ExecuteReader(CommandBehavior.CloseConnection);
return reader;
}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
Label1.Text = "";
Label1.Text += "productName:" + ddlProduct.SelectedItem.Text + "<br/>";
Label2.Text = "";
Label2.Text += "IDANDPRICE:" + ddlProduct.SelectedItem.ToString() ;
}

I find the following errors:
1- cast number filed to nvarchar in sql query
2- set AutoPostBack property of listbox to true
3- use ddlProduct.SelectedItem.Value for label2
I create a page and use your code and apply above suggestion, the following code work perfectly.
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false) bindListBox();
}
private void bindListBox()
{
ddlProduct.DataSource = getReader();
ddlProduct.DataTextField = "name";
ddlProduct.DataValueField = "IdAndName";
ddlProduct.DataBind();
}
private SqlDataReader getReader()
{
//get connection string from web.config
string strConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
SqlConnection myConnect = new SqlConnection(strConnectionString);
string strCommandText = "SELECT Id,Name,CAST( id as nvarchar(10) )+'-'+Name as IdAndName FROM Product";
SqlCommand cmd = new SqlCommand(strCommandText, myConnect);
myConnect.Open();
SqlDataReader reader = cmd.ExecuteReader(CommandBehavior.CloseConnection);
return reader;
}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
Label1.Text = "";
Label1.Text += "productName:" + ddlProduct.SelectedItem.Text + "<br/>";
Label2.Text = "";
Label2.Text += "IDANDPRICE:" + ddlProduct.SelectedItem.Value;
}
}

Asp Dropdownlist does not return selected value. (Dropdownlist is Databound)

I have created a dropdownlist, which loads its data from a table column. Now I want to select the value of dropdownlist on Index_change_event.
protected void Page_Load(object sender, EventArgs e)
{
string username = Session["username"].ToString();
SqlConnection con = new SqlConnection("Data Source=DLINK\\SQLEXPRESS;User ID=sa;Password=logmein;Initial Catalog=AndroidAppDB");
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
con.Open();
string query = "select Fence_Name from Fence where Username='" + username + "'";
SqlCommand command = new SqlCommand(query, con);
DropDownList1.DataSource = command.ExecuteReader();
DropDownList1.DataValueField = "Fence_Name";
DropDownList1.DataTextField = "Fence_Name";
DropDownList1.DataBind();
con.Close();
//arr = Session["arr"].ToString();
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
if (!IsPostBack)
{
Label2.Text = DropDownList1.SelectedItem.Value;
}
}

Remove if (!IsPostBack) from DropDownList1_SelectedIndexChanged event and if (!IsPostBack) should be on Page_Load event.
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
Label2.Text = DropDownList1.SelectedItem.Value;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string username = Session["username"].ToString();
SqlConnection con = new SqlConnection("Data Source=DLINK\\SQLEXPRESS;User ID=sa;Password=logmein;Initial Catalog=AndroidAppDB");
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
con.Open();
string query = "select Fence_Name from Fence where Username='" + username + "'";
SqlCommand command = new SqlCommand(query, con);
DropDownList1.DataSource = command.ExecuteReader();
DropDownList1.DataValueField = "Fence_Name";
DropDownList1.DataTextField = "Fence_Name";
DropDownList1.DataBind();
con.Close();
}
}

You are only checking !IsPostBack. As the event is firing from a postback this will never be run. Also, be careful that you are not re-binding the datasource and therefore changing the selected value on page_load.

facing an error with registration btn

When I fill the registration form and click on the button to move to user panel it does not move to the user panel, it freezes on the registration. In the user panel code behind it shows this message:

The problem might be your Session["UsrNme"] is null
if (Session["UsrNme"] != null)
{
USRNMElbl.Text = Session["UsrNme"].ToString();
}
else
{
return;
