    <p>I understand that you want to set two nested loops accounting for an undetermined number of elements (items in an array of <code>DataGridView</code>, I presume), performing the checks you want:</p> <pre><code> For count1 As Integer = 1 To dgvCont 'Assuming indices from 1 to dgvCont For row1 As Integer = 0 To Main.DGVM(count1).Rows.Count - 1 If (Main.DGVM(count1).Rows(row1).Cells(0).Value Is Nothing) Then Continue For Dim val1 As String = Main.DGVM(count1).Rows(row1).Cells(0).Value Dim found As Boolean = False For count2 As Integer = 1 To dgvCont 'Assuming indices from 1 to dgvCont If (count2 = count1) Then Continue For For row2 As Integer = 0 To Main.DGVM(count2).Rows.Count - 1 If (Main.DGVM(count2).Rows(row2).Cells(0).Value Is Nothing) Then Continue For Dim val2 As String = Main.DGVM(count2).Rows(row2).Cells(0).Value.ToString() If val1 = val2 Then Dim cm As String = val1 If cm = "" Then Else Analysis.lvCmn.Items.Add(val1) End If found = True Exit For 'By assuming that you want to stop searching after finding a match End If Next If (found) Then Exit For 'By assuming that you want to stop searching after finding a match Next Next Next </code></pre> <p>Your code is not too clear (neither what you want); but this should give you a good enough start to carry out the implementation you are looking for. Bear in mind that this code (like yours) only considers one column (first one); in case of wanting to iterate through all the columns, you would have to add further nested loops accounting for that.</p>

    2. CO@JadejaRJ this is what this code is doing with limitations (just looking in the first column and looking for just one match of each value). I hope that you understand that this is not a custom software development service and that this answer is way beyond what might be considered acceptable under the current conditions (question focused on your specific problems and not too much effort from your side (your code represents a pretty poor attempt)). Please, feel free to ask any question but I hope that my position is clear enough.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
