    <p>hi I am trying to implement a form which resizes using coding. I have use the form_paint method to paint a border but I cannot "paint over" this border. What i am intending to do is that as i resize the form using a timer for a "smooth resizing", the form border would be updated along with the resize. what should i do?</p> <pre><code> Pen setupControlPen = new Pen(SystemColors.Control, 16); Pen setupDimGrayPen = new Pen(Color.DimGray, 5); </code></pre> <p>inside my form_paint: //draws a form border</p> <pre><code> Rectangle newRectangle; newRectangle = new Rectangle(new Point(0, 0), new Size(this.Width - 1, this.Height - 1)); setupGraphics.DrawRectangle(setupDimGrayPen, newRectangle); </code></pre> <p>inside a click event: //i tried to draw over the already drawn border.</p> <pre><code> Rectangle newRectangle = new Rectangle(new Point(0, 0), new Size(this.Width - 1, this.Height - 1)); setupGraphics.DrawRectangle(setupControlPen, newRectangle); </code></pre> <p>thank you!</p> <p>update: I tried using both resize_form event and timer to redraw but still cannot re-draw the border whenever i resize the form.</p> <p>update 2: the override method works! regarding the setupGraphics:</p> <pre><code> //global space Graphics setupGraphics; //form_load setupGraphics = this.CreateGraphics(); //so whenever I want to draw something during an event, supposing a button click event to draw a line: setupGraphics.DrawLine(pen, point1, point2); </code></pre> <p>I would like to ask are there any flaws in this method? or should everything be done inside the form_paint method?</p>

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.
