I am need to compare 2 items from 2 separate drop down lists. These values are of int type. Say for example 2 drop down lists showing years. Now i need to find out these 2 years selected is greater or nearer to the current year.
I tried converting the values i receive from the drop down lists to int variables. But i am getting error then. I gave it like below.
int tmp = Convert.ToInt32(ddl_1.SelectedItem.Text);
this gives an error like this - Input string was not in correct format.
I need to know how to put an item from a drop down list to a variable of int data type.
I am completely new to SQL server i know a few of the basics. I have a VS2010 asp.net c# application with two dropdown listboxes and a textbox. I need to calculate the numbers e.g 3 + 3 = Medium, using the table below to calculate the answer so i can insert the output value into a textbox.

In my WPF application I created a LINQ to SQL entities class. Then I created a partial class and there add code to my entity class. Below is the code of it:
Then I executed LINQ to SQL. Works perfectly well. Then I bound WPF Datagrid radiobutton column to is_selected property of the partial class. Below is XAML code:
And here I have the problem. When I'm changing the radiobutton status from Unchecked to Checked it doesn't change the value of is_selected property from false to true in the partial class. I don't know why.
passing selected row in gridview to my dropdown. I have 1 gridview, 1 textbox and 1 dropdown list box. My dropdown is populated by SqlDataSource from my table Country. On my gridview, I have 3 columns, which are SELECT, NAME and COUNTRY. Under SELECT column, I have my hyperlinked Select, every time I clicked on a certain row NAME will pass in textbox (no problem with that), but in my dropdown it does not populates the COUNTRY that I choose. For example, I have Jack for name and USA for country. Beside Jack and USA, I have a hyperlink Select, when I click Select, Jack will display on my textbox and supposed to be USA will display on my dropdown but not displaying instead it says an error "'cboCountry' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value".
I have a Gridview ,in that one of the Column is DropDownList .I have 10 Records in my Grid and my DropDown Values are like this 1,2,3....10.This is the format to store my DropDown values ,if i delete 4th Row ,then my DropDown Values are Changed like 1,2,3,4....9.This is my task ,but i'm getting this format 1,2,3,--,5...10.

And I always get an error that is not explained dont know whether is coz i bootstrapped my master page or what but all errors caught where there are it shows this Runtime Error

My understanding is that the rhs of line 1 construct only a temporary object. getMe() then return the reference of this temp object and bind it to thg (as a lvalue reference). After line one, the temp object is really destroyed (hence the first output line). At this point thg is really binding to a destroyed, invalid object. But somehow the 2nd line still prints the correct value of 10 is because the memory storage is not yet corrupted (still holding the previous value). Is this correct?
I'm using winforms and I want to set a checkbox on a dropdown menu item, but I don't know how to access the dropdown menu items.
I know ToolStripMenuItem items are attached to ContextMenuStrip items but I'm not sure how to navigate into the ToolStripMenuItem section to read/set those menu items.
ToolStripMenuItem listbox_font_size; cmsListBox = new ContextMenuStrip(); cmsListBox.Items.Clear();
I'm having issues with selecting the next item in sequence in a combobox dropdown. The dropdown consists of letters A-Z and there is a timer that I have running to change the letter every x minutes. What I need to do is if, for example, letter A is selected, when the timer goes off, it will change to letter B, etc. If it's at letter Z, it needs to go back to the first item, letter A.
I'm having issues with drawing a flat style dropdown menu in XP.
Here is the custom dropdown menu element:
public class FlattenCombo : ComboBox { private Brush BorderBrush = new SolidBrush(SystemColors.WindowFrame); private Brush ArrowBrush = new SolidBrush(SystemColors.ControlText); private Brush DropButtonBrush = new SolidBrush(SystemColors.Control); public Color HighlightColor { get; set; }

And here's what it should look like (this is how it's rendered in Windows Vista/7):
I have a txt file of drinks, and I want to meak a list of buttons of it (the txt file is build like this: fanta : 2 ), how can I make buttons of all the drinks ( I get the first one in a button , but not the others).
Dictionary<string, double> drank = new Dictionary<string, double>(); string[] words = new string[8]; Button button; <Button> BtnList = new List<Button>();
I am trying to query an Informix database using a List<T> collection's elements as variables. I can build the list and connect to the database, but I am unsure how to iterate through the list and query the database for each item in the collection.
My list is of type string, and contains Order Numbers. I want to query item information for each order number in the list.
I want to display the content of my database in list view. The table has 5 columns however when I tried this code
string view = "Select * from cust_infor"; SqlCommand cmd = new SqlCommand(view,FL.clsconnection.opencon()); SqlDataReader dr = cmd.ExecuteReader(); listView1.Items.Clear(); while (dr.Read()) { listView1.Items.Add(dr[0].ToString()).SubItems.Add(dr[1].ToString()); }
It limits the display to 2 columns. List view will only show the first 2 columns. The code above won't let me add more indexes or subitems. Only up to 2 columns.
I am grabbing data from three entities and want to grab a field value in each of the entites and place it in an arraylist. What I would like to do is loop through the arraylist for all the values and do something for each value only once. If the value in the array list is repeated, I want to not do anything for it and continue till the end. Basically, I loop through all the values do something for each value and skip over the repeated value if I already did something.
For school we have to create a blackjack game using windows form. I had to store the images of each card into a sorted list so i created a class called cardList and created a constructor which contained the the sorted list called cards. So it looks kinda like this:
public class cardList : Form1 { SortedList cards = new SortedList(); public cardList()
[Code]....
There's probably a few other errors, I'm still trying to figure this whole c# thing out. why the error tells me (on the line that contains c.cards.GetByIndex(cardNumber);) that cards is inaccessible due the its protection level.
How do I bind a DATE column in a DataGridView Control to a DatePicker control (using C#)? I already have the DataGridView control bound to a database stored procedure which takes a DATE value as a parameter and selects joining table based on the results.
Code: struct _Node { // list node _Genptr _Next; // successor node, or first element if head _Genptr _Prev; // predecessor node, or last element if head _Ty _Myval; // the stored value, unused if head };
The stored value is wasted space for the list head. Is there any advantage to implementing list using the same structure for a list head and node?
// Write a function called insertEntry() to insert a new entry into a linked list.
Have the procedure take as arguments a pointer to the list entry to be inserted (of type struct entry as defined in this chapter), and a pointer to an element in the list after which the new entry is to be inserted.
// The function dveloped in exercise 2 only inserts an element after an existing element in the list, thereby prenting you from inserting a new entry at the front of the list.
(Hint: Think about setting up a special structure to point to the beginning of the list.)
This is a working version of the exercise, but I don't think I'm doing what's asked. I was able to add an element to the beginning of the list using an if statement, not creating a special structure that points to the beginning of the list. How would I go about creating a special structure that points to the beginning of the list to add a new element at the beginning of the list?
I'm trying to display a list of MSMQ messages in a list box based on a drop-down list holding the environment.So i've setup the binding and i know that the list loads but nothing shows up in the list? I should be setting like a display member or something but i'm not entirely sure
