Convert Button Click to Page Load - c#

I have an ASP button click method that I want to change from a user clicking the button
<asp:Button id="createInvoice" runat="server" OnClick="InvoiceBtn_Click" Text="Create Invoice button" />
to executing on Page_Load:
protected void Page_Load(object sender, EventArgs e)
{
AsyncMode = true;
if (!dictionary.ContainsKey("accessToken"))
{
if (Request.QueryString.Count > 0)
{
var response = new AuthorizeResponse(Request.QueryString.ToString());
if (response.State != null)
{
if (oauthClient.CSRFToken == response.State)
{
if (response.RealmId != null)
{
realmId = response.RealmId;
if (!dictionary.ContainsKey("realmId"))
{
dictionary.Add("realmId", realmId);
}
}
if (response.Code != null)
{
authCode = response.Code;
Session["authcodes"] = authCode;
output("Authorization code obtained.");
PageAsyncTask t = new PageAsyncTask(performCodeExchange);
Page.RegisterAsyncTask(t);
Page.ExecuteRegisteredAsyncTasks();
}
}
else
{
output("Invalid State");
dictionary.Clear();
}
}
}
}
else
{
oauth.Visible = true;
connected.Visible = true;
}
}
#region button click events
public async void InvoiceBtn_Click()
{
if (dictionary.ContainsKey("realmId") && dictionary.ContainsKey("accessToken"))
{
Action<ServiceContext> apiCallFucntion = new Action<ServiceContext>(CreateInvoiceCall);
await QBOApiCall(apiCallFucntion);
}
else
{
lblQBOCall.Visible = true;
lblQBOCall.Text = "Access token not found.";
}
}

I changed the final else statement and final line in the method and it works. I'm sure it needs refactoring but it works.
else
{
oauth.Visible = true;
connected.Visible = true;
InvoiceBtn_Click(createInvoice, EventArgs.Empty);
}
InvoiceBtn_Click(createInvoice, EventArgs.Empty);

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)
{

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.

Showing virtual keyboard when clicking on a textbox inside WebControl

You need to use javascript for that. You need to know when that textfield is focused like this:
Check if focus is on a textfield
And then once the focused event is fired on JavaScript you should call your WPF function for showing the keyboard up. Here's useful hints:
How to programmaticaly check if a text input box inside a web page loaded in WPF Browser has focus?

how to run multiple background process in a button

I am having a problem. I am new in c#. In this code when I click the button2, it will run bgutures.RunWorkerAsync(); only. But I need to modify it such like if I click on button2, all items the checkedListBox1.allitems contains are download, one by one in bgworker. Can anyone please help in this.
My code is :
private void button2_Click(object sender, EventArgs e)
{
button2.Enabled = false;
string DayAtoZ = " ";
string DayDead = " ";
string Dayutures = " ";
string Daysify = " ";
string Dayfx = " ";
if (checkedListBox1.SelectedItem == "")
{
}
else if (checkedListBox1.SelectedItem == Dayutures)
{
}
else if (checkedListBox1.SelectedItem == DayAtoZ)
{
}
else if (checkedListBox1.SelectedItem == Daysify)
{
}
else if (checkedListBox1.SelectedItem == DayDead)
{
}
else if (checkedListBox1.SelectedItem == Dayfx)
{
}
{
bgutures.RunWorkerAsync();
}
{
bgDead.RunWorkerAsync();
}
{
bgsify.RunWorkerAsync();
}
{
bgAtoZ.RunWorkerAsync();
}
{
}
}
Instead of one BackgoundWorker use as many as your need.
if (checkedListBox1.SelectedItem == "")
{
var worker = new BackgroundWorker();
.. do setup
worker.RunWorkerAsync();
}
else if (checkedListBox1.SelectedItem == Dayutures)
{
var worker = new BackgroundWorker();
.. do setup
worker.RunWorkerAsync();
}

cannot see the label content when a item is selected from dynamically added dropdownlist

I have a Dropdownlist (DDL1) when I select any item from this dropdownlist(DDL1), results in creation of another dropdownlist(DDL2), This contains some of the items.When I select other Item from DDL1 , Items will change in DDL2, this happens for the each different item selected in DDL1.
when I select a item from DDL2, label content must be shown, intially I'm making Label invisibe and in the code I changed the visibility to true and added content to it. But the label content is not shown when I select a item from DDL2.
Here is my Code
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
if (DropDownList1.SelectedValue == "Abe Books")
{
DropDownSeller.Visible = true;
lnkUsdBooks.Visible = true;
lnkUsdBooks.Text = "usedbooks#abe.com";
lnkUsdBooks.NavigateUrl = "mailto:usedbook#abe.com";
DropDownSeller.Visible = true;
DropDownSeller.Items.Remove("Chacha Choudary");
DropDownSeller.Items.Remove("SpiderMan");
DropDownSeller.Items.Remove("Amar chitra Katha");
DropDownSeller.Items.Remove("Chandamama");
DropDownSeller.Items.Remove("Mahabharata");
DropDownSeller.Items.Add("Amar chitra Katha");
DropDownSeller.Items.Add("Chandamama");
DropDownSeller.Items.Add("Mahabharata");
DropDownSeller.DataBind();
if (DropDownSeller.SelectedValue == "Amar chitra Katha")
{
lblPrice.Visible = true;
lblPrice.Text = "$69.99";
}
else if (DropDownSeller.SelectedValue == "Chandamama")
{
lblPrice.Visible = true;
lblPrice.Text = "$59.99";
}
else if (DropDownSeller.SelectedValue == "Mahabharata")
{
lblPrice.Visible = true;
lblPrice.Text = "$49.99";
}
else
{
lblPrice.Visible = false;
}
}
Any ideas on this are appreciated
Thanks,
Remove if (!Page.IsPostBack) from the DropDownList1_SelectedIndexChanged because when the page postbacks this condition will be false. Because your page is posting back to the server that's why it is not visible and not showing.
In short your DropDownList1_SelectedIndexChanged should be like..
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
if (DropDownList1.SelectedValue == "Abe Books")
{
DropDownSeller.Visible = true;
lnkUsdBooks.Visible = true;
lnkUsdBooks.Text = "usedbooks#abe.com";
lnkUsdBooks.NavigateUrl = "mailto:usedbook#abe.com";
DropDownSeller.Visible = true;
DropDownSeller.Items.Clear(); // it will clear all the items, instead you are removing one by one
DropDownSeller.Items.Add("Amar chitra Katha");
DropDownSeller.Items.Add("Chandamama");
DropDownSeller.Items.Add("Mahabharata");
DropDownSeller.DataBind();
}
protected void DropDownSeller_SelectedIndexChanged(object sender, EventArgs e)
{
if (DropDownSeller.SelectedValue == "Amar chitra Katha")
{
lblPrice.Visible = true;
lblPrice.Text = "$69.99";
}
else if (DropDownSeller.SelectedValue == "Chandamama")
{
lblPrice.Visible = true;
lblPrice.Text = "$59.99";
}
else if (DropDownSeller.SelectedValue == "Mahabharata")
{
lblPrice.Visible = true;
lblPrice.Text = "$49.99";
}
else
{
lblPrice.Visible = false;
}
}
