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.

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 tried the codes below:
protected void GridView2_SelectedIndexChanged(object sender, EventArgs e)
{
txtname.Text = GridView2.SelectedRow.Cells[1].Text;
cboCountry.Text = GridView2.SelectedRow.Cells[2].Text;
}
Only the textbox os working, no luck at all in dropdown...I'm using c# and asp.net.

I am using visual studio 2010, in my windows form I have 4 textboxes and 3 button in it, for my 1st textbox when I entered one of my ProductCode such as 10111, then press the Display button, the other remaining 3 textboxes should populate and display the following;
ProductID: CH001
ProductName: Chocolate Strawberry
ProductCode: 10111
Then the 2 remaining button named NEXT and PREVIOUS, should be able to display all my product name with 10111 product code.

I have managed to make text dynamically appear in a text-box while I enter text into another.
how ever I would like to know to to limit the amount of text that is dynamically entered(I'd say about 10 characters at most).
here's a sample of what I have done so far:
Random r = new Random();
int IDrandom = r.Next(0, 9);
Emp_ID.Text += IDrandom.ToString();
//Emp_ID.MaxLength = 10; does not work

I'm trying to get some more user friendly things in my program done. Now I'm trying to filter by typing in a text box and it filters to what you are typing and shows the entire row.
This is what I currently have:
private void txtFilter_TextChanged(object sender, EventArgs e) {
try {
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
[Code] ....
I get an exception error though:
SQLite error
near "'N'": syntax error
// N is what I started typing to start the filter.
Ok, so I've edited the code now to this:
private void txtFilter_TextChanged(object sender, EventArgs e) // FILTER TODO {
DataView view = new DataView();
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
view.RowFilter = "Channel like '%" + txtFilter.Text + "%'";
}
No more exception errors, just not what I want it to do. It just keeps everything there.
