Yes I think it is. I expect you'll have to define IComparable on the class you use to represent a row of the grid, so that you can do a search on the collection. I've not tried it but I vaguely remember seeing an online article somewhere which did this.

Do you mean a DataTable?

I'm going to guess that you do, or that you have a datatable feeding both the DG and the Arraylist.

Anyways, you can adjust the datatable.defaultview.filter property with SQL-like filter parameters.

No I don't have a datatable..
I have an object filled by a stored procedure.
The datagrid is filled by calling the fetch function on the class

Thanks

OK, fill a datatable with the fetch function and then make that the datagrid's datasource.

OK. On some event (button click or textbox changed), set the DataTable.DefaultView.RowFilter = " Field like " + TextBox.Text

Master pages and menus

Hi,

Can anyone see the problem here? I have a very simple master page with a very simple content page. I just want a menu on the master page. There are several things that aren't working the way I would like them to.

1. The menu is horizontal and pushing the content place holder down when it's expanding down. I would like it to hover over the content page and not move it.

2. it's not displaying the items when hovering. It's just displaying a white box where the items are suppose to be.

I have been looking at this for 2 days without any progress. Can someone help me?

Found it. In the epms web.config, there is a line

<system.web>
<xhtmlConformance mode="Legacy"/>
</system.web>

This was causing my problem.

calculating with measurements

Hi,

I'm trying to make a project which "converts" for example from meters to centimeters. I fill 20 labels with a random generated question containing a "fromUnit" and "toUnit" object.

Here is my code:

public partial class Metrics : Form
{
private double[] _answer;
private TextBox[] _textBox;
private Label[] _labels;

public Metrics()
{
InitializeComponent();
this._answer = new double[20];
this._textBox = new TextBox[20];
this._labels = new Label[20];
this.label1.Text = this.getQuestion(1, 10);
}

private string[][] lengths = new string[][]
{
new string[] {"kilometer", "1000"},
new string[] {"hectometer", "100"},
new string[] {"decameter", "10"},
new string[] {"meter", "1"},
new string[] {"decimeter", ".1"},
new string[] {"centimeter", ".01"},
new string[] {"millimeter", ".001"}
};

public string[] getUnit(int index)
{
return lengths[index];
}

private string getQuestion(int minLength, int maxLength)
{
// Create Random object
Random rand = new Random((int)DateTime.Now.Ticks);

int length = rand.Next(minLength, maxLength); // Gets the length to convert
int randNumber1 = rand.Next(0, 6); // gets the first unit random number
int randNumber2 = rand.Next(0, 6); // gets the second unit random number

while (randNumber1 == randNumber2) // loop ensure that units are not the same
{
randNumber2 = rand.Next(0, 6);
}

string[] fromUnit = getUnit(randNumber1); // gets the unit details from class
string[] toUnit = getUnit(randNumber2); // gets the unit details from class

// gets the answer (i.e. (23 * .(01 / .001)) = 230)
this._answer = length * (Convert.ToDouble(fromUnit[1]) / (Convert.ToDouble(toUnit[1])));

//return the question string
return "How much is " + length.ToString() + " " + fromUnit[0] + "(s) in " + toUnit[0] + "(s)?";
}

private void btnCalculate_Click(object sender, EventArgs e)
{

}

private void FillLabelsWithQuestions()
{
foreach (Control label in this.Controls)
{
if (label is Label)
{
label.Text = getQuestion(1, 100);
}
}
}
}

The problem is, i don't know how to check if the answer is correct which is entered in a textbox and checks the answer when the button "calculate" is pressed, because there are strings involved too.

My labels are named like this:

label1
label2
label3
etc

And so are my textboxes:

textbox1
textbox2
.....

This is a screenshot of how my Form looks like:

Anyone any suggestion?

Thanks in advance!

I wouldn't use a multidimensional string array. There are many other better options.

If you stay with the current array, you can store your answers in another array. Then check each answer against that array.

Hi edboe,

I ran out of options how to do it and the multidimensional seems to work.

Do you have a sample for me about that "check each answer against that array"?

Thanks in advance!

1 read the whole text in that file and put in a string.
2 split the string by "\n" and you will get array of strings
use it to get the line number.
3 when you extract the line go the your char

When you get mad...THINK twice that the only advice

you can read in the textfile into a string and then select the character you want.
You could also read in the textfile line per line, put it in a string and select the character.

Look into StreamReader class and string class on MSDN.

hope this helps.

What stancrm has written is correct.

You can use the 'Enabled' property of System.Windows.Forms.Control
