ListItem.Selected returning false

I have a listbox with a list of items that get loaded when you navigate to a certain page. Then I have an on click that passes parameters to an AddProducts method. That method is what loops through all selected items and inserts values from the fields filled in as well as takes the values from the listItems and adds them as parameters to a stored procedure.
The problem I'm running into is that when looping through the listItems
if(selectedItem.Selected) is returning false, but in my method where I load the listbox I initialize a SelectedValue so I'm not sure why it's giving me the error message I have for no selected items. I was able to get it to work yesterday before I moved LoadListBoxCategories outside of LoadAddData but unsure as to why that would have any effect to if(listItem.Selected).
I'm relatively new to asp.net so any help/ explanation as to why my code isn't working is extremely appreciated. I've spent the last three days trying to figure this out and haven't found a solution that works.
Code:
Page_Load:
protected void Page_Load(object sender, EventArgs e)
{
if (Session[IS_LOGGED_IN] == null)
{
Response.Redirect("/utilities/companydata/login.aspx", true);
return;

gvTextInputs.RowEditing += new GridViewEditEventHandler(gvTextInputs_RowEditing);

The list box instance is recreated on the server-side during the postback (as well as entire page). You do not set the selected items in the Page_Load event handler - if (!IsPostBack) goes to else branch. This is why you don't see them.

Ok,
lstCategoriesBox.Items.Clear();
Ok, above goes nuclear - blows out the list, blows out the selection.
Ok, that's fine
lstCategoriesBox.Items.Add(new ListItem("--Select--", null));
lstCategoriesBox.DataTextField = "productName";
lstCategoriesBox.DataValueField = "CombinedValue";
Ok, above adds a new item. Should be ok, but one should setup the lb BEFORE adding any data - including that "--select--" row.
It just makes sense to "setup" the lb and THEN start adding data, right?
However, But, if above works - ok, then lets keep going, but I would setup the lb before adding any rows of data. Say like this:
lstCategoriesBox.DataTextField = "productName";
lstCategoriesBox.DataValueField = "CombinedValue";
lstCategoriesBox.Items.Add(new ListItem("--Select--", null));
Now, the next line:
lstCategoriesBox.SelectedValue = curCategoryProductTypeId;
Ouch! - we just cleared the lb, and now we trying to set it to a value? You can't do that - the lb just been cleared, right? You would need to load up the lb first, and THEN you can set it to the selected value, right?
I might be missing something here, but that lb needs to be loaded up with valid data BEFORE you attempt to set the selected value?

To test first, change following
Outcome Category.InnerText = list CategoriesBox.SelectedValue;
to
Category.InnerText = Request.Form["CategoriesBox-ClientID"]
If the data is coming in correctly, the list view cleared or reloaded when between reload and click events the page.

UPDATE: I just figured it out! So stupid but when I check if(selectedItem.Selected) since I'm looping through the ListBox items it starts at the first index of the ListBox and since the first isn't selected then that if goes to the else block. Remove the else and it works fine

How to use iTextSharp to populate radio button

I have a table and one of the column is YesNo which is of type varchar(3). I have two radio buttons in my PDF file which is in an array:
pg1rb (radio group field)
--> c1 (radio button one (yes))
--> c2 (radio button two (no))
I set textboxes like this in my code:
formFieldMap["topmostSubform[0].Page1[0].f1_01_0_[0]"] = reader.GetValue(0).ToString();
How can I select YES or NO radio button based on the row value?
Can I do something like this:
formFieldMap["pg1rb"] = reader.GetBoolean(10); //10 is the 9th column which is Yes/No value
Or do I get the value and based on it select the radio button, something like this:
if (reader.GetValue(10).ToString() == "Yes") {
formFieldMap["pg1rb"][c1] = "1";
else {
formFieldMap["pg1rb"][c2] = "1";
}

Your question was confusing because it used a reader object that didn't refer to iTextSharp's PdfReader class and it used a formFieldMap object of which the type was unknown (it doesn't seem related to iTextSharp). Your edit was very welcome to understand the question.
The field names you mention look as if they are fields in an XFA form, but the article you refer to talks about filling out AcroForm documents, so let's assume that your form was indeed born as an XFA form, but later on converted to an AcroForm.
In this case, nobody will be able to tell you which values to pick to set the radio buttons without seeing the PDF. Please download chapter 6 of my book and read section 6.3.5, more specifically where it says Inspecting the form and its fields. On page 183, you can read that the possible values for a group of radio buttons is either "Off"–no radio button is selected— or a code that is defined in the form itself.
For instance: in the example from the book, the possible values for the category group were spec, toro, anim, etc...
This means that you can set a radio box in that group like this:
formFields.SetField("category", "spec");
or:
formFields..SetField("category", "toro");
or:
formFields.SetField("category", "anim");
and so on.
So, if you want to set a radio button in a radiogroup named pg1rb, you first need to know which are the possible values. You assume that the possible values are "Yes" and "No" in which case you could use:
formFields.SetField("pg1rb", "Yes");
or
formFields.SetField("pg1rb", "No");
But the possible values could also be "1" and "0", "On" and "Off", "true" and "false",... The possible values were chosen by the person who created the form.
You can get these values programmatically by using the code from page 182:
StringBuilder sb = new StringBuilder();
sb.Append("Possible values for pg1rb:");
sb.Append(Environment.NewLine);
states = form.GetAppearanceStates("pg1rb");
for (int i = 0; i < states.Length - 1; i++) {
sb.Append(states[i]);
sb.Append(", ");
}
sb.Append(states[states.Length - 1]);
Inspect what was written to the sb object and you have the values you are looking for.

Dynamically change a button image according to database information

I'm trying to change several button images according to what state I get in the database.
If I get any state "0" I should change the button image to a "busy" image, since the default image is a "free" one.
So my question is: How can i change a button through a variable name?
I have this code for now(i know its wrong):
private void checkSuites()
{
SqlCeCommand checkSuite = new SqlCeCommand("SELECT * FROM RentSessionLog WHERE State='0'", mainConnection);
SqlCeDataReader readSuite = checkSuite.ExecuteReader();
int suiteIndex;
string suitePath = "suite" + suiteIndex;
while (readSuite.Read())
{
suiteIndex = Convert.ToInt32(readSuite["SuiteNum"]);
suitePath.Image = NewSoftware.Properties.Resources.busySuiteImg;
}
}

It's as simple as:
while (readSuite.Read())
{
suiteIndex = Convert.ToInt32(readSuite["SuiteNum"]);
switch(suiteIndex)
{
case 0:
{
suitePath.Image = NewSoftware.Properties.Resources.busySuiteImg;
break;
}
default:
{
suitePath.Image = NewSoftware.Properties.Resources.freeSuiteImg;
}
}
}
Edit:
The reason I used a switch is in case you have other-states appearing in the future. You have "Busy" and "Free", but there could be "Reserved" as well and you may want to have further conditions that would just get obfuscated in a simple if else if sequence.

I believe you need to use this.Controls.Find(suitePath, true) to turn your string into a control. I am presuming that "suite" + suiteIndex is the .Name of each of your buttons.
string suitePath = "suite" + suiteIndex;
Button suiteButton = this.Controls.Find(suitePath, true);
suiteButton.Image = ...
See more details about Controls.Find
Alternatively for quicker access, you may want to keep a Dictionary<int, Control> with each of your buttons in it.

I DID IT! Using a dictionary as Thymine said:
public void checkSuites()
{
Dictionary<int, Control> btnList = new Dictionary<int, Control>();
btnList.Add(1, suite1);
btnList.Add(2, suite2);
btnList.Add(3, suite3);
btnList.Add(4, suite4);
btnList.Add(5, suite5);
SqlCeCommand checkSuite = new SqlCeCommand("SELECT * FROM RentSessionLog WHERE State='0'", mainConnection);
SqlCeDataReader readSuite = checkSuite.ExecuteReader();
while (readSuite.Read())
{
int suiteIndex = Convert.ToInt32(readSuite["SuiteNum"]);
string suitePath = "suite" + suiteIndex;
foreach (Button key in btnList.Values)
{
if (key.Name == suitePath)
{
key.Image = NewSoftware.Properties.Resources.busySuiteImg;
}
}
}
}
Thank you all who helped :D

Combobox - setting datasource clears Items

I have a routine that populates a combobox from a database; the first time the combo is populated, it all works perfectly, but if I try to do it again, the combobox is completely blank. I narrowed it down to this line:
cboThis.DataSource = cboThis.Items;
This seems to clear the Items collection for the combobox...but only if the combo was already populated.
Any ideas what could be going on here?
There IS an event handler for one of the combo's SelectedIndexChanged event, but this doesn't seem to get called by anything but the first and last lines of code.
Here's the complete routine:
public void ComboFromDB(ComboBox cboThis, string strTable, string strField)
{
cboThis.SelectedIndex = -1;
cboThis.DataSource = null;
cboThis.Items.Clear();
string strQuery = #"SELECT ID, " + strField + " FROM " + strTable;
using (SqlConnection sqcConnection = new SqlConnection(strConnection))
{
sqcConnection.Open();
SqlCommand sqcCommand = new SqlCommand(strQuery, sqcConnection);
SqlDataReader dr = sqcCommand.ExecuteReader();
while (dr.Read())
{
cboThis.Items.Add(new ComboItem((int)dr[0], dr[1].ToString())); //this all works fine
}
}
cboThis.DataSource = cboThis.Items; //This line clears cboThis.Items...
cboThis.ValueMember = "ID";
cboThis.DisplayMember = "Display";
cboThis.SelectedIndex = -1;
}
Cheers

try to create a structure like this
struct tmpItems
{
//member variables
private Int32 _ID;
private String _Display;
//properties
public Int32 ID
{
get {return _ID;}
}
public String Display
{
get {return _Display;}
}
public tmpItems(Int32 pID , String pDisplay)
{
_ID = pID;
_Display = pDisplay;
}
}
now assign
ArrayList dataItems = new ArrayList();
dataItems.Add(new tmpItems((int)dr[0], dr[1].ToString()));
then finally set
cbothis.DataSource = dataItems;
cboThis.ValueMember = "ID";
cboThis.DisplayMember = "Display";
Ensure that ComboBox SelectedIndexChange event handles the Initialization of data..
because while setting datasource , the items will be added one by one.. each time generating SelectedIndexChangeEvent .. but will find difficult in accessing SelectedValue property at this stage

In the end I binned using Items and just shoved it through a Dictionary.

How to access a string variable outside

public void Button1_Click(object sender, EventArgs e)
{
String a = DropDownList1.SelectedItem.Value;
String b = DropDownList3.SelectedItem.Value.PadLeft(3, '0');
String c = TextBox1.Text.PadLeft(5, '0').ToString();
String d = TextBox2.Text.ToString();
String digit = a + b + c + d;
try
{
OdbcConnection casetype = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=localhost;Database=testcase;User=root;Password=root;Option=3;");
casetype.Open();
//************to get case type
string casetypequery = "select casename from casetype where skey=?";
//************to get case type
OdbcCommand casetypecmd = new OdbcCommand(casetypequery, casetype);
String casetypefromdropdown = DropDownList3.SelectedItem.ToString();
casetypecmd.Parameters.AddWithValue("?", casetypefromdropdown);
using (OdbcDataReader casetypeMyReader = casetypecmd.ExecuteReader())
{
while (casetypeMyReader.Read())
{
String casename = casetypeMyReader["casename"].ToString();
}
}
}
catch (Exception ewa)
{
Response.Write(ewa);
}
I am not able to access
String casename = casetypeMyReader["casename"].ToString();
which is inside while loop in my above code.
How can i access
'casename'
outside while loop?i want to use it to put the content in HtmlEditor(ajax)

If you want to access the variable outside the loop you need to declare it outside:
string casename = "some default value";
while (casetypeMyReader.Read())
{
casename = casetypeMyReader["casename"].ToString();
}
// You can access casename here and it's value will either be the default one
// if the reader returned no rows or the last row being read.

You could declare an Array or List of strings outside the loop, and save the casename values in that.
List<string> caseNames = new List<string>();
while (casetypeMyReader.Read())
{
caseNames.Add(casetypeMyReader["casename"].ToString());
}
Now they're all in the array and you can access it wherever.
If there are duplicates, and you need unique values, you can do caseNames.Distinct().ToList() afterwards.
