    <p>I'm using a databound listbox in a C# WinForm application. </p> <p>When I click on an item in the listbox nothing else on the form works, even when I click on the close button the form doesn't close. Everything works fine until I select an item. </p> <p>What I have tried to do is in the listbox1_SelectedIndexChanged set the listbox1 focus to false but that didn't work. </p> <p>Code sample: This is the code that assigns the listbox to the data source:</p> <pre><code>this.ListBox1.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", this.table1BindingSource, "PrimaryKeyId", true)); this.ListBox1.DataSource = this.table1BindingSource; this.ListBox1.DisplayMember = "Name"; this.ListBox1.Font = new System.Drawing.Font("Microsoft Sans Serif", 14.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0))); this.ListBox1.FormattingEnabled = true; this.ListBox1.ItemHeight = 24; this.ListBox1.Location = new System.Drawing.Point(185, 28); this.ListBox1.Name = "ListBox1"; this.ListBox1.Size = new System.Drawing.Size(660, 532); this.ListBox1.TabIndex = 7; this.ListBox1.ValueMember = "Name"; this.ListBox1.SelectedIndexChanged += new System.EventHandler(this.ListBox1_SelectedIndexChanged); </code></pre> <p>ListBox1 isn't referenced anywhere else. This is the initial code I was using before: </p> <pre><code>private void ListBox1_SelectedIndexChanged(object sender, EventArgs e) { ListBox1.Focus().Equals(false); } </code></pre> <p>This is the code I am now running: </p> <pre><code>private void ListBox1_SelectedIndexChanged(object sender, EventArgs e) { GroupBox1.Focus().Equals(true); } </code></pre> <p>Then on Windows load I have: <code>table1TableAdapter.Fill(this.Application1DataSet.Table1);</code> I've debug the windows load and the listbox1 method so I don't think it's a loop. Also the app doesn't crash so I don't think it's a loop.</p>

    2. COCan you post a code sample? Make sure you are not doing something else when you click the item - maybe you disable everything or you get in an infinite loop on the main thread.

    3. COUnless there's somewhere else a loop could exist. There isn't a lot of code in the project in the first place.

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.
