View 1 RepliesI am trying to make a style that only gets applied if the parent element of the element that the style refers to, has another specific style. Kind of like in CSS where you can do ".class1 .class2" to specify that the "class2" theme only applies if it is within an element with the class "class1". I do not wish to use any form of external DLLs or libraries for this task. I want to know if it's possible to implement on my own.
I've tried using MultiTriggers with no luck. I have a style that applies to all TextBlocks. I want the textblock to do the following: If the font-size of the textblock is 11 and the parent element's style is "PinnedSuggestion", set the foreground color to "#FF505050". If the font-size of the textblock is 11 and the parent element's style is "Suggestion", set the foreground color to "#FFCCCCCC". The conditions that I have tried to write to make this work, are as follows (the font-size condition is true, but the other one is not). The conditions are inside a style that applies to all textblocks in general.

I am creating an application and am very new to VB. I have 4 buttons on my form which is like my applications main menu. I would like that each of the buttons behaves in the following way when there is a mouse rollover: The Button back color is changed from the default to Red The Button text is changed to Blue, Bold, and increases in font size I would also like all the buttons to go back to their initial state when the mouse leaves.
Another thing, instead of me writing code for each of the buttons event handlers (Mouse Hovers, and Mouse Leaves) is there a way I can write this code once, maybe as a function and then always call it for any button that I create from here on so that any new buttons take on this behaviour.

I use code to connect datagridview with datasource is
CODE:
DataGridView filtering. I have this data bound to a combobox:
Product Index
Prod1 1,2
Prod2 7,8,9
Prod3 10,11
Actual Table structure is:
Index Product
1 prod1
2 prod1
7 prod2
8 prod2
9 prod2
10 prod2
11 prod3
(Product is the Display Member, Index is the ValueMember)
On the combobox's SelectedIndexChanged event, I'm filtering the DataGridView:
DGVCustomers.DataSource.DefaultView.RowFilter = "indexes like '%" + MyDropDown.SelectedValue + "%'"
If MyDropDown.SelectedValue is "1,2" then any record without either number will not be shown , in addition "7,8,9" will only show customers with that string... etc etc. How can I filter the DGV correctly with the CSV style data? (It's not my data unfortunately!)

I am developing a project using VB2010. In the attached example I created a Form.
On tha form I put a GroupBox Containing a DataGridView.
I am trying to set, at Design time, the ColumnHeadersDefaultCellstyle Font of the grid, defining the Font, the size and the style (Bold). After saving the project or running it, The Font properties of the grid headers are changed to the Font properties of the containing
GroupBox.
Why is that so? How can I set, at Design Time, a different font for the Grid Column headers and the GroupBox?
To demostrate the problm - Try to modify the Font of the grid headers, in the attached example,
to "Bold" "Size 12", Run the application and see the result.
I've made a function to convert a number and fraction string eg. "22 7/8" to decimal. I've no problem pulling the data from the current row cell to pass through the function. Checked it via a temp textbox i put on the form. What i actuall want to do is pass it back to another cell on the current row. Tried a few things but having no luck. Here's the code of what works. The name of the cell i'm trying to pass the result back to is called "BaseDec".

I have added a custom Control to my project, but every time I edit it and rebuild the form that I use the custom control in adds the project name in front of the control and won't compile. i.e. Project name = MyProject, Custom Control name = MyControl. When I rebuild the project after editing my control I get an error, MyProject.MyControl doesn't exist. If I remove the MyProject from the line it compiles and runs fine until next time I edit the custom control.
I can't figure out what I would be doing wrong to cause this, or why it is putting the project name in front of the control, but then not accepting it. I am also struggling figuring out how to change the back color on an individual cell in an Datagridview Combo Box. The style.backcolor property of the cell doesn't seem to do anything.
How I can change the back color of a single cell of a datagridview in runtime?

View 3 RepliesI've been professionally writing VB.NET software for seven years. However, I don't have a strong computer science background - four courses while studying education at university in the 90s that gave me some CS basics and exposure to Pascal, C and Lisp. Anyway, there are a whole bunch of practices that I'm missing - testing, patterns, "real" object-oriented design, etc and I'm trying to pick them up. If you look at most of my applications, you find blocks of fairly old-school procedural code being triggered by form events. Where I write my own classes, I'm mostly using them as data-structures with overloaded New() methods and maybe a custom output method. I consider myself quite proficient at this kind of work and none of my employers has had any problems with it. But it's not really right and I'd like to learn more of the craft of my trade.
Since the early 90s, I've looked at several different intro to objects kind of documents -- books, tutorials, etc. They seem to all use dogs and cars as analogies and examples with tons of responsibilities per object. And they've never stuck with me even as I wanted to learn from them.Lately, I've been reading "Uncle" Bob Martin's notions of OOD and I like what I see. But it's hard for me to follow the C/Java syntax and I get hung up on that difficulty rather than just ingesting it smoothly. So I'm looking for good sources with VB examples because that is (by far!) the syntax with which I am most comfortable. There's not much around. The stuff that I find doesn't seem to advocate or exemplify e.g. the Single Responsibility Principle.
I've been looking for books, but they mostly seem like they're either OOP and not in VB or VB and not (really) OOP. I've checked out the following topics here: 1, 2 and 3 -- among others. I've scrutinized the Amazon reviews of most of the books listed in those threads and keep coming up with reasons to suspect that they aren't really what I'm looking for.
So, any ideas? If you're going to suggest a book, I'd like to hear how well it fits the needs that I've outlined. If you think I'm on the wrong track, I guess I'd be interested to hear why. If you have other suggestions on how to pursue this avenue of improvement, that too would be great.
I have an app, which has a form. a tab is at the center of the form. the tab is a normal tab, and it has 3d style. today, I was adjusting something, and forgot what I changed. suddenly, all controls become flat style. especially, I have datagrid in the form. in the grid, one cell is a dropdownlist style. before i can change how many items to show when is clicked. now, it does not change. now, even I add a control on another form which is in the same app, the style is flat too. what can cause this? very weird.
