  Hi, I need to have a Button on a ToolStrip that would look like a normal windows button(elevated/projecting) as opposed to the flat default appearence.How do i do that Also if i need to set the border color of a ToolStripTextBox do i have to create a class deriving from ToolStripRenderer and if so how would i set this Could someone help me how i can achieve the above 2 Thanks in advance.. If the provided ToolStrip controls do not suit your needs then your needs then your best option is to build your own based on ToolStripControlHost so as to host a button inside of a compatible type that can be added to the ToolStrip.

• billb59 How To: Implement Single click navigation to a DataGridView Combo Box Cell

  I have a data grid view bound to a data view, with a combo box bound to another data view. The user's are complaining that they have to click twice on the combo box drop down arrow to get the drop down list to appear -- what's happening as near as I can tell is that the first click selects the row, and the second click is delivered to the combo box. Is it possible to modify this behavior so that a single click both selects the row and drops down the combo box I suspect this is not as simple as overriding WndProc in the DataGridView and passing the WM_CLICK message to the combo box :-) Thanks in Advance Alan You can also use the CellMouseClick event. That way the combo box doesn't drop down when tabbing into i ...Show All

  Hi, I have a control in a form. On the control I have a "KeyDown" event handler that works perfectly for all the keys, except for the UP/DOWN/LEFT/RIGHT keys.

• Gosovic Help in implementation of a magnifying glass

  I have an image viewer application which I want to apply a magnifying glass effect on certain area of the image. The problem I've run into is that when I slowly dragged the magnifying glass across (when left mouse down) the magnifying glass window didn't move smoothly. I believe it has something to do with drawing the graphics of the original image on the background. May someone please help me solve this issue Thanks. I got your project and was able to reproduce the problem. You are not using the 32bppPArgb pixel format I recommended. First off, you get flicker (the white shimmer around the rectangle) because the panel isn't double-buffered. Check out this thread for a custom panel that avoids this. Se ...Show All

• sai111 How can I handle in the child class an event raised in the parent class?

  Hi all I am creating a class that inherits from System.Windos.Forms.Form for implementing some custom things that I want to happen for each form used later in my app. I am overriding the OnClose event of the form for the following reason: I want so recursively search each control on the form and if the control is a Component One TrueDBGrid then I call the UpdateData() function on it. When calling UpdateData() on a TrueDBGrid an event called AfterUpdate() of the TrueDBGrid is raised.

• Nirth Detecting the Letter Clicked

  Hello, I'm creating an interactive program, and I render labels one after another down the control. When the user clicks on a word in the label, I want to write an algorithm to detect which word was clicked. Has anybody done something like this I have an idea how to do it, but am not quite sure. Thanks. Hey, Thanks, that was what I was thinking; though I was going to go one letter at a time, using sizing to determine whether we selected the targeted letter; label is on one line, though sometimes is multi-lined, so I figured when I size the entire line, I will have to perform a math calculation to count the number of rows. I use the same font as the form, so that will be good... Thanks. ...Show All
