Session Lost after refresh Page

i have this sets of code with setsession and getsession in it
protected void btnCall_Click(Object sender, EventArgs e)
{
if (isCallComplete())
{
Collection<Greeting> collGreeting = sessionHelper.GetSession("CurrentGreetingData") as Collection<Greeting>;
if (collGreeting.Count > 0)
{
Collection<CounterbySA> collCounterBySA = new ServiceFacade(User).SelectByFieldName<CounterbySA>("SAID", 106);//CurrentApplicationUser.id
if (collCounterBySA.Count > 0)
{
Counter counter = new ServiceFacade(User).SelectById<Counter>(collCounterBySA[0].CounterID);
Greeting greeting = collGreeting[0];
BoardQueue boardQueue = new BoardQueue();
boardQueue.BranchID = CurrentApplicationUser.BranchID;
boardQueue.CounterID = counter.ID;
boardQueue.SAID = 106; //CurrentApplicationUser.ID
boardQueue.PlatNumber = greeting.PlatNumber;
boardQueue.Status = (int)CallCustomerStatus.Open;
ResultStatus rs = new ServiceFacade(User).InsertBoardQueue(boardQueue);
voiceCall(string.Format("{0}di{1}", greeting.PlatNumber, counter.Name));
MessageBox.Show(string.Format("{0} Silahkan ke {1}", greeting.PlatNumber, counter.Name));
btnCall.Enabled = false;
btnReCall.Enabled = true;
btnComplete.Enabled = true;
sessionHelper.SetSession("CurrentCallData", boardQueue);
sessionHelper.SetSession("CurrentGreetingTemp", greeting);
}
else
{
MessageBox.Show("SA ini Belom terdaftar di Loket, Silahkan ke manu AssignSA untuk mendaftarkan/menempatkan SA ke Loket");
}
}
else
{
MessageBox.Show("Tidak Ada Customer Untuk Di panggil");
}
}
else if (isCurrentUser())
{
MessageBox.Show("sedang memanggil customer, click panggil ulang apabila customer belum datang");
btnCall.Enabled = true;
btnReCall.Enabled = true;
btnComplete.Enabled = true;
}
else
{
MessageBox.Show("SA lain sedang memanggil Customer, harap menunggu");
}
so if i click button call it will set the 2 session
and this where i get the session
protected void btnReCall_Click(Object sender, EventArgs e)
{
BoardQueue boardQueue = sessionHelper.GetSession("CurrentCallData") as BoardQueue;
if (boardQueue != null)
{
Counter counter = new ServiceFacade(User).SelectById<Counter>(boardQueue.CounterID);
voiceCall(string.Format("{0}di{1}", boardQueue.PlatNumber, counter.Name));
MessageBox.Show(string.Format("{0} Silahkan ke {1}", boardQueue.PlatNumber, counter.Name));
btnNext.Enabled = true;
}
else
{
MessageBox.Show("Harap Memanggil Customer terlebih Dahulu");
}
}
Before the page is refresh it works fine. but after the page refresh the session is gone.
i have done some research about this topic but i couldn't get the answer
Here are the get and set method for the session
public void SetSession(string sKey, object sValue)
{
HttpContext.Current.Session[sKey] = sValue;
AddSession(sKey, true);
}
public object GetSession(string sKey)
{
return ((object)(HttpContext.Current.Session[sKey]));
}

Assigning checkbox a value from gridview

I am selecting a row from Gridview, working good except for checkbox, like I am assigning value of checkbox retreived from gridview to checkbox that is placed on web form but it isn't represented by checkbox on form, it shows empty checkbox in every case
if (gridviewDesignations.SelectedRow.Cells[5].Text == " ")
{
chkIsHead.Text = gridviewDesignations.SelectedRow.Cells[5].Text;
}
in short, checkbox is not picking value from gridview
Update:
tried this too:
CheckBox chkIsHead = (CheckBox) gridviewDesignations.SelectedRow.Cells[5].Controls[0];
if (chkIsHead.Checked == false)
{
chkIsHead.Checked = false;
}
else
{
chkIsHead.Checked = true;
}
Update:
my full code:
public partial class frmDesignations : System.Web.UI.Page
{
AccessibleVariables accessVariables = new AccessibleVariables(); //Used to access global variables
public void Clear(params TextBox[] txtBoxes)
{
foreach (TextBox txtbx in txtBoxes)
{

}
}

ddlDepartments.DataTextField = "DepName";
ddlDepartments.DataSource = ds.Tables[0];
// ddlDepartments.SelectedIndex = -1;
ddlDepartments.DataBind();

I believe the following is what you need to do:
Then select EditProgrammatically.
I'm not sure if yoou'll need to manually put data into the grid though but that won't be too hard. Examples can be seen here : http://msdn.microsoft.com/en-us/library/system.data.datatable(v=vs.110).aspx
PS : You can set the DataSource in the grid view to the DataTable.

clear each thing after doing achieving a specific task

i am working on an software in which i want to clear each thing after doing achieving a specific task, like clearing all the fields, list view etc etc and i've to write the a lot of things to be cleared off, like the code of my new button is:
private void btnNew_Click(object sender, EventArgs e)
{
txtProductCode1.ReadOnly = false;
txtInvoiceNo.ReadOnly = false;
cmbCustoemerType.Enabled = false;
cmbCustomerName.Enabled = false;
button1.Enabled = true;
txtProductCode1.Text = null;
txtWageName.Text = null;
txtWageCost.Text = null;
btnFirst.Visible = false;
btnPrevious.Visible = false;
btnNext.Visible = false;
btnLast.Visible = false;
cmbProductName.Enabled = true;
txtQty.ReadOnly = false;
txtPercant.ReadOnly = false;
txtDiscount.ReadOnly = false;
cmbCustoemerType.Enabled = true;
cmbCustomerName.Enabled = true;
button5.Enabled = true;
btnDelete.Enabled = true;
dtp1.Enabled = true;
btnSave.Text = "&Save";
cmbCustoemerType.Text = null;
cmbCustomerName.Text = null;
txtInvoiceNo.Clear();
txtDiscount.Clear();
txtGrandTotal.Clear();
txtProductName.Clear();
txtSalePrice.Clear();
txtQty.Clear();
txtTotal.Clear();
txtExtraWages.Text = null;
lvExtraWages.Items.Clear();
lvTransaction.Items.Clear();
lblCount.Text = null;
lblNetTotal.Text = null;
txtPercant.Text = null;
txtInvoiceNo.Text = invoice.ToString();
}
is there any way to get rid of writing the code again n again, like i need to enable one thing which i've disabled here on another button so i have to write reverse code of this to achieve the task and it's really annoying! is there any other way to do this?
EDIT:
tried following code:
private void btnNew_Click(object sender, EventArgs e)
{
//using setboxdefault function
SetTextBoxDefaults();
cmbCustoemerType.Text = null;
cmbCustomerName.Text = null;
cmbCustoemerType.Enabled = false;
cmbCustomerName.Enabled = false;
cmbProductName.Enabled = true;
cmbCustoemerType.Enabled = true;
cmbCustomerName.Enabled = true;
button5.Enabled = true;
btnDelete.Enabled = true;
button1.Enabled = true;
btnFirst.Visible = false;
btnPrevious.Visible = false;
btnNext.Visible = false;
btnLast.Visible = false;
btnSave.Text = "&Save";
lvExtraWages.Items.Clear();
lvTransaction.Items.Clear();
lblCount.Text = null;
lblNetTotal.Text = null;
dtp1.Enabled = true;
txtInvoiceNo.Text = invoice.ToString();
}
private void SetTextBoxDefaults()
{
var textBoxes = GetControls(this, typeof(TextBox));
foreach (var textBox in textBoxes)
{
TextBox.Clear();
}
}
public IEnumerable<Control> GetControls(Control control, Type type)
{
var controls = control.Controls.Cast<Control>();
return controls.SelectMany(ctrl => GetControls(ctrl, type)).Concat(controls).Where(c => c.GetType() == type);
}
but it's giving error on TextBox.Clear(); , error is Error 4
An object reference is required for the non-static field, method, or property 'System.Windows.Forms.TextBoxBase.Clear()'
Please let me know where i am mistaking..!!

As Tim has suggested, you can iterate though the controls and set each one accordingly..
public IEnumerable<Control> GetControls(Control control,Type type)
{
var controls = control.Controls.Cast<Control>();
return controls.SelectMany(ctrl => GetControls(ctrl,type)).Concat(controls).Where(c => c.GetType() == type);
}
private void btnNew_Click(object sender, EventArgs e)
{
SetComboBoxDefaults();
SetTextBoxDefaults();
SetButtonDefaults();
}
private void SetComboBoxDefaults()
{
var comboBoxes = GetControls(this, typeof(ComboBox));
foreach (var comboBox in comboBoxes)
{
((ComboBox)comboBox).Enabled = false;
((ComboBox)comboBox).Text = null;
}
}
private void SetTextBoxDefaults()
{
var textBoxes = GetControls(this, typeof(TextBox));
foreach (var textBox in textBoxes)
{
((TextBox)textBox).Clear();
}
}
private void SetButtonDefaults()
{
var buttons = GetControls(this, typeof(Button));
foreach (var button in buttons)
{
((Button)button).Visible = false;
if (button.Name == "btnSave") ((Button)button).Text = "&Save";
}
}
You can also have separate GetControl methods so that it returns a specific type of Control, reducing the need to cast to derived types.
update for edit:
You are using the TextBox type instead of the variable name in the foreach loop. Update it to use textBox (lowercase), not TextBox (pascal) see below:
private void SetTextBoxDefaults()
{
var textBoxes = GetControls(this, typeof(TextBox));
foreach (var textBox in textBoxes)
{
((TextBox)textBox).Clear();
}
}

Remember to stay DRY
Don't
Repeat
Yourself
Partition the reset logic into suitable, small methods that reset a logical grouping of controls. Then invoke those methods where and as needed.

What I have done in several such cases is this:
void SetTextBoxReadOnly(bool val, param TextBox[] textBoxes)
{
if(textBoxes != null && textBoxes.Length > 0)
{
foreach(TextBox textBox in textBoxes)
{
if(textBox != null)
{
textBox.ReadOnly = val;
}
}
}
}
void SetControlEnabled(bool val, param Control[] ctrls)
{
if(ctrls != null && ctrls.Length > 0)
{
foreach(Control ctrl in ctrls)
{
if(ctrl != null)
{
ctrl.Enabled = val;
}
}
}
}
// etc set of methods for similar situations.
// there methods can be invoked as
...
...
...
SetTextBoxReadOnly(true, txtProductCode1,
txtInvoiceNo,
txtQty,
txtPercant,
txtDiscount);

shivery effect of the GUI prepared using C# windows forms

For file transfer between the client and server systems we have a GUI designed on the client system using C# windows forms. We have added a lot of background images and text boxes to make the GUI impressive. But whenever we execute the client code, the GUI takes a few seconds to load itself and be stable , before a choice from the GUI can be made. This happens after every request made from the client side GUI.(its like all the form elements vanish and appear again in a short span of time ). Please help with this. May i know the reason for it.

Try using below code in your form constructor.
this.DoubleBuffered = true;
It should improve some performance. Windows forms are not made to display lot of images overlapped on each other.

Need help getting listbox item text from secondary form to main form

I have been looking all over the Internet for this and have found similar, but none of it will work for me. Everything I have found assumes the listbox is on the main form and not the secondary form, or the code is for an older version of C# or Visual Studio (I am using VS2008).
I am creating a web browser that has a button on the main form (called frmMyBrowser) to open a dialog (frmBookmarks) with a listbox (lstBookmark) with bookmarked URLs. I need to be able to double click on an item (the bookmarked URL) and have the text pasted into the address bar (cmbAddress) of the main form.
Any help would be GREATLY appreciated.

I figured out that if I create the window at runtime, I can get it to work. In case anyone is interested, the code I used is below.
public void frmMyBrowser_ShowFavorites(object sender, EventArgs e)
{
frmFavorites.ShowIcon = false;
frmFavorites.ShowInTaskbar = false;

frmFavorites.MaximizeBox = false;

frmFavorites.Text = "Bookmarks";
frmFavorites.Width = 500;
frmFavorites.Height = 350;
frmFavorites.Controls.Add(lstFavorites);
frmFavorites.Controls.Add(btnRemoveFavorite);
frmFavorites.Controls.Add(btnAddFavorite);
frmFavorites.Controls.Add(btnCloseFavorites);
frmFavorites.Controls.Add(txtCurrentUrl);
lstFavorites.Width = 484;
lstFavorites.Height = 245;
btnRemoveFavorite.Location = new Point(8, 280);
btnAddFavorite.Location = new Point(8, 255);
btnCloseFavorites.Location = new Point(400, 255);
txtCurrentUrl.Location = new Point(110, 255);
txtCurrentUrl.Size = new Size(255, 20);
btnAddFavorite.Text = "Add";
btnRemoveFavorite.Text = "Remove";
btnCloseFavorites.Text = "Close";
txtCurrentUrl.Text = wbBrowser.Url.ToString();
btnAddFavorite.Click += new EventHandler(btnAddFavorite_Click);
btnRemoveFavorite.Click += new EventHandler(btnRemoveFavorite_Click);
frmFavorites.Load += new EventHandler(frmFavorites_Load);
btnCloseFavorites.Click += new EventHandler(btnCloseFavorites_Click);
lstFavorites.MouseDoubleClick += new MouseEventHandler(lstFavorites_MouseDoubleClick);
frmFavorites.Show();

}

}
}
