• AtomZ .be need help with properties while creating usercontrol

  Hi, I'm creating a usercontrol with some public properties to display in the propertywindow. I want to display the properties under category. like how we have form.size category has some properties. Please help me with this. venp I think you want that PLUS sign and when you click it the 3 properties will show. I thought you just want them in their own category block, ex. Misc, Layout, and etc. If you want the plus sign, you will need to create a single property that has the 3 properties as its own sub-properties. You can achieve this by using a class to group the 3 properties. class MyCategory {   // define the 3 properties } class MyUserControl {   public MyCategory Changeable = new MyCategory(); // ...Show All

• Alexey Raga Is there a Scale Bug?

  I'm developing in VS2005 (C++/CLI) on a machine with a resolution of 1600x1200. I have a form (Form1 built with the designer) that contains several controls including GroupBoxes, TextBoxes, ListBoxes, DataGridViews and Labels. When the form is run on machines with 1024x768 or lower it will not scale. Only the upper left part of the form shows and the user cannot see the rest of the form nor can he expand the form to see the entire form. Scroll bars do not appear regardless of the AutoScroll property setting. I have tried setting the form's AutoScaleMode property to Font and to Dpi with no success. I've also tried using AutoScroll to no avail. I did some looking in Debug and made an interesting discovery. With the AutoScaleMode proper ...Show All

• flandercan :: I have never succeeded in hiding a property ::

  Here is my situation: I have a control inherited from MaskedTextBox . I added a property called Value . I want the users of this new control to use the Value property and not use the Text property when setting a new value to this control. Therefore my intention is to hide the Text property from external use. I tried making the property Private but that doesn't work. Anyone have an idea Thank you. Thank you to the both of you for you ideas and suggestions, i will try them out. And yes the idea behind this was to in fact hide it from the code and designer. I will let you know if I succeed. Thanks again. Great to see developers help each other. :) ...Show All

• mpetanovitch DataGridView, BindingNavigator, and New Row

  Hi, I have a DataGridView and a BindingNavigator bound to the same BindingSource (which is in its turn bound to a DataTable from a typed DataSet). DataGridView.AllowUserToAddRow = True, so the New Row is visible. I've noticed that clicking the BindingNavigator.AddNewItem button does not select the New Row. In stead, it creates a new record at the end of the DGV, just before the New Row. Is this default behaviour, or does it behave like this because of something in my code (Sorry if this is explained somewhere else and I missed it. Seems like a straightforward scenario to me, but I couldn't find any explanation.) Because of this behaviour, calculating and setting default values for the new row isn't as straightforward as it see ...Show All

• cdaviduik Loading Controls based on contents of a database

  Hey everyone, I have question about loading controls based on the contents of a database. So I'm building a windows application that uses a fairly large database, about 100,000 records. I have about three tables in my database. I have to create three forms for each table, o, by the way, the tables are related to each other.

In short, whatever the user selects on the previous form, a id is pass to a query and results of this query should display on the next form. S ...Show All

• Stuart McHugh Problem with Automatic Text Wrapping and MeasureString

  I've been trying to create my own Chart control, and I've been having a problem printing the labels against the x-axis. I divide the x-axis into the number of elements being displayed on the chart. I then measure the width of the text of the labels, to make sure they fit, using MeasureString and passing it a RectangleF to work out if all the characters fit in. My problem is that when I call MeasureString, the charactersFitted parameter comes back with weird information. Say I meaure the string "30th Birthday Celebrations", and "30th" and "Birthday Celebrations" are printed on 2 lines (the second only saying "Birthday Cel". The MeasureString returns 14 characters fitted and 2 lines I can't ...Show All
