    <p>Ok, in my app there are times when loading the DataGridView can take a minute or two. What I want to do is show a <a href="http://www.pozzware.com/images/edit/wait.gif" rel="nofollow noreferrer">GIF</a> in a form with no border until it reaches the end of the loading function. However, if I do:</p> <pre><code>Views.Loading ldw = new Views.Loading(); ldw.Show(); ... ldw.Close(); </code></pre> <p>...it never actually draws it to the screen and I can't see it. If I do ShowDialog(), it shows the window but never gets past that line of code. I have a feeling it's because it's not a background worker or because the focus gets set back to the parent because of processing...I don't know.</p> <p>My form is a blank form, added a picture box, added a gif to the picture box, and made FormBorderStyle = none. Any and all help is appreciated.</p> <p><b>Update: Current (non-working) Code</b><br></p> <pre><code> private void InitializeBackgroundWorker() { //Defines the DoWork Event Handler for _backgroundWorker. _bgWorkerReports.DoWork += new DoWorkEventHandler(bgWorkerReports_DoWork); //Defines the RunWorkCompleted Event Handler for _backgroundWorker. _bgWorkerReports.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bgWorkerReports_RunWorkerCompleted); } private void bgWorkerReports_DoWork(object sender, DoWorkEventArgs e) { ldw.Show(); try { string strFilter = ""; if (!_strSearchFilter.Equals("")) { strFilter += strFilter.Equals("") ? " " + _strSearchFilter : " and " + _strSearchFilter; } if (tvFigure.Nodes.Count &gt; 0) { if (_strFigureFilter == "ALL") { strFilter += " " + Constants.GetColumnName("Figure") + " LIKE '%%' "; } else if (!_strFigureFilter.Equals("") &amp;&amp; !_strFigureFilter.Equals(tvFigure.TopNode.Name)) { if (_strSearchFilter.Equals("") || !cbCurrentFigure.Checked) { strFilter += strFilter.Equals("") ?

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).
