• Mark Fasano BorderColor for a Standard Button

  Hi, It is rather straight forward to change the border color for a flat style button control. The color properly is not listed for a standard style, and I dod not see a public property or method to alter the color by the program either. Not prefer to draw border lines for each control, is there a quicker way to just change the standard button bordercolor property Regards, Reza Bemanian Hi Reza, For standard style you will need to draw the border lines yourself. Thanks, Standard/system style buttons are painted according to the current Windows XP theme or system colors. Buttons do not implement custom drawing so you can't change their appearance. Unless you create your own butto ...Show All

• Navya Jeevan How to make a control not take keyboard input

  Hi, I'm in the process of writing a small C# App, in which i have two groupboxes in a form. The form has the KeyPreview property set to true. The groupbox1 contains a set of labels. The second groupbox contains a few checkboxes and a button. I wrote a form1_keypress handler to handle keyboard inputs directed at the form. But once the groupbox2 receives focus (if i change one of the checkboxes or click on the button), even before i can handle keyboard events (an arrow key press) with the form1_keypress event, i see that the groupbox2 state changes (the checkbox value changes). Or in other words, the groupbox2 still is in focus and i reach the form1_keypress only after having the state of the controls in groupbox2 changed. I want all the ...Show All

• DmitryMS Adding TreeNode nodes to treeview1.Nodes[index] ?

  I want to biuld a tree from a XML file, but I can't seem to get the following to work: treeView1.Nodes.Add( new TreeNode ( "year") ); treeView1.Nodes[0].Nodes.Add( new TreeNode ( "month" )); int noTreeNodes = treeView1.Nodes.Count; // Should return 2, but only returns 1 treeView1.Nodes[noTreeNodes].Nodes.Add( new TreeNode ( "day" )); The problem is that nodes are only indexed if added as in the first line, not the second line Therefor the last line fails, since it tries to get the Node with index 1, which does not exist. Any help appreciated! The nodes have a tree structure. So treeView1.Nodes.Count only returns the count of the top nodes which is 1. To add the day under t ...Show All

• Jack Spade Modeless Dialog boxes that are Always in Focus

  How do you make a modeless dialog box so that it is always in focus with the parent window Like the floating menus in Photoshop, for example. Whatever I do, I haven't found a way to keep more than one window in focus at a time. Thanks, so they only make it look like they are always in focus by having it so the border colour doesn't change when they are out of focus. Bump. I can't find an answer to this using a search either here or on the web.   Lot's of people ask focus questions, most of which never get a satisfactory answer. Isn't their a Wondows Forms Focus FAQ somewhere     I'm looking at a ...Show All

• Ezira Can I store a bitmap file in a globally accessable file, instead of a form's imagelist?

  Hello, I am aware of the methods for storing images in an imagelist that resides on a form. But sometimes my tree node does not have the form's pointer. I would like to store some of my bitmaps in a globally accessable singleton object. Has anyone done this Thanks for the help! Bob Thanks Peter! I am not acually using the common control. I can mention which tree control I am using if that matters. But I am creating derived node objects, and I can assign the image from the singleton (This is already working). My question is more about how to store the images in a resX file and retrieving them in all the places my application needs bitmaps. This also allows me to centralize my bitm ...Show All

• mterui Populating Multiple TextBox Controls from ComboBox with Concatenated Items

  I need to populate the text property of two textbox controls via a value selected from a comboBox. The comboBox is populated via dataReader and the items are created via concatenated fields (this is kind of a look-up comboBox). Usually I would assign the text property of the textbox control like this: string sItem = ComboBox.SelectedItem.ToString(); TextBox.Text = sItem; Because my comboBox selectedItem is a concatenated field, I do not know how to populate the two textboxes. I tried using the comboBox.ValueMember but that is always null (I'm assuming because the comboBox is not really databound ). What can I do to populate the textboxes This is how I populate the comboBox: private void populateCompanyName() { OleDbData ...Show All
