    <p>Looking at your code it seems to me that you're adding text items to the ListBox, so of course it's not easy to get the salary from that.</p> <p>Instead, you should pass the Employee object to the the listbox to keep all the necessary informations; in this way, your adding method would be :</p> <pre><code> private void btnSave_Click(object sender, EventArgs e) { var empid = Convert.ToInt32(txtEmployeeID.Text); var empfirstname = Convert.ToString(txtEmployeeFirstName.Text); var emplastname = Convert.ToString(txtEmployeeLastName.Text); var empsalary = Convert.ToDouble(txtSalary.Text); var emp = new Employee(empid, empfirstname, emplastname, empsalary); lstEmployeeData.Items.Add(emp); } </code></pre> <p>Of course, to get the desired display text you need to re-define <code>ToString()</code> method of Employee, for example like this:</p> <pre><code> class Employee { // other methods... public override string ToString() { return this.EmployeeToString(); } } </code></pre> <p>Finally, when the button "show employee having the minimum salary" is clicked you should simply do something like this:</p> <pre><code>private void btnLowestSalary_Click(object sender, EventArgs e) { var minSalary = lstEmployeeData.Items.OfType&lt;Employee&gt;().Min(x =&gt; x.Salary); var empWithMinSalary = lstEmployeeData.Items.OfType&lt;Employee&gt;() .First(x =&gt; x.Salary == minSalary); string msg = string.Format("{0} has the lowest salary of {1}", empWithMinSalary.EmployeeFirstName, minSalary); MessageBox.Show(msg); } </code></pre> <p><strong>EDIT :</strong></p> <p>In case more than one employee have the same salary you can do something like this:</p> <pre><code>private void btnLowestSalary_Click(object sender, EventArgs e) { var minSalary = lstEmployeeData.Items.OfType&lt;Employee&gt;().Min(x =&gt; x.Salary); var empsWithMinSalary = lstEmployeeData.Items.OfType&lt;Employee&gt;() .Where(x =&gt; x.Salary == minSalary); foreach(var e in empsWithMinSalary) { string msg = string.Format("{0} has the lowest salary of {1}", e.EmployeeFirstName, minSalary); MessageBox.Show(msg); } } </code></pre> <p>Or better:</p> <pre><code>private void btnLowestSalary_Click(object sender, EventArgs e) { var minSalary = lstEmployeeData.Items.OfType&lt;Employee&gt;().Min(x =&gt; x.Salary); var empsWithMinSalary = lstEmployeeData.Items.OfType&lt;Employee&gt;() .Where(x =&gt; x.Salary == minSalary); string names = ""; foreach(var e in empsWithMinSalary) names += Environment.NewLine + e.EmployeeFirstName; string msg = string.Format("The following emplyoees have the lowest salary of {0} : {1}", minSalary, names); MessageBox.Show(msg); } </code></pre>

    2. CO@JackBrown: I obviously don't know the name of the property containing the salary, and according to your comment it seems you forgot to expose that. You need to expose a public property in Employee containing the salary and use that instead of x.Salary...

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.
