    <p>I have written a code that displays 6 DataGridView tables with values from excel that contain exchange rates for euros and us dollars from 6 different banks. The exchange rates are imported from excel file. Now i have to compare each of them and display the min value for euro buy rate (Куповен курс) and max value for sell rate (Продажен/Откупен курс) and min value for dollar buy rate (Куповен курс) and max value for sell rate (Продажен/Откупен курс). I need some help with C# code that will compare those values and display them in a TextBox by clicking the Compare button.</p> <p>Here is pic from my app:</p> <p><a href="http://uploadpic.org/v.php?img=CYRmqhbE6F" rel="nofollow">http://uploadpic.org/v.php?img=CYRmqhbE6F</a></p> <p>I tried with this code, but give me error:</p> <pre><code>private void button7_Click(object sender, EventArgs e) { string s = dataGridView1.Rows[1].Cells[1].Value.ToString(); string t = dataGridView2.Rows[0].Cells[6].Value.ToString(); string k = dataGridView3.Rows[0].Cells[1].Value.ToString(); string l = dataGridView4.Rows[0].Cells[4].Value.ToString(); string m = dataGridView5.Rows[0].Cells[2].Value.ToString(); string n = dataGridView6.Rows[0].Cells[3].Value.ToString(); string[] kupoven = new string[] { s,t,k,l,m,n}; int length = kupoven.Length; int last = length - 1; int largest = kupoven[]; for (int i = 1; i &lt;= length / 2; i++) { if (kupoven[i] &gt; kupoven[last] &amp;&amp; kupoven[i] &gt; largest) largest = arr[i]; else if (kupoven[last] &gt; largest) largest = kupoven[last]; last--; } return largest; } </code></pre> <p>With this i put all euro values in strings(s,t,k,l,m,n), then i put them in array, and then i try to get the max value from the array. I think the problem is with type string.</p>

    3. COYah, there is nobody in here that is going to give you code unless you show the code that you've already tried. The best way to use SO is to try something and if you're having a specific problem then ask a question, but hardly anybody is going to write fully functional code for you.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
