I have a large number of forms with a lot of controls on them and i need to do specific actions with certain groups of controls. Is it possible to select all elements with the same type using vs winforms designer? or using other instruments?
It's not a problem when i'm using custom controls where i can implement my own controlDesigner and override Verbs property (for example), but unfortunately most of them are common.
"I need to do specific actions with certain groups of controls" is pretty vague. If you are trying to change or insert a property to controls with a specific name or property value, you could try a global search and replace of the form.designer.cs files. Depending on what you're changing, this will be used by, overwritten by, or completely break the designer.
If you want a better answer you will have to describe what you're trying to do.

I need to put many controls on form during design. Each time I must scroll in Properties in order to find and change control name name. Is it possible somehow change controls name in fast way during design?
Sorry, but currently native Visual Studio does not have the function you want.
You can press F4 on the control to quickly enter the property interface, but you need to find the Name property modification by yourself.
Using code modification is also an option if many controls need to be modified.
I have an existing custom control library with controls which may contain properties: HeaderStyle, ModalStyle, Collapsable, etc...
In the user interface the program is currently displaying a categorized list of these properties. I am trying to update this code to hide properties they dont normally use. I have a list of properties to hide/show based on button click but I am not sure how I can hide these fields programmatically.
I would like to retain any values entered into the fields before hiding and re-display the values if the fields are shown again.
Here is a property that current exists but would like to be hidden/shown on toggle.
/// <summary>ModalStyle property for control</summary>
[XmlAttribute]
[DefaultValue(Utility.Common.Enumerations.ModalStyle.None)]
[Category(PropertyCategories.Rendering)]
[Description("Modal dialog style")]
public ModalStyle? ModalStyle
{
get { return control.ModalStyleActive; }
set { control.ModalStyle = value; }
}
My original though was to do some variant on #if DEBUG but use my own Conditional however I was unable to find a way to change my conditionals via button/toggle.
Can anyone please help with a solution to my problem? I have 20-30 controls with 20 to 30 properties that would like to be filtered.
I have two suggestions that, while they may not give you the exact functionality desired, will keep your solution much more straight forward.
First:
Since you are the library developer you should just decide what properties you want other developers to have access to though the IDE properties window. If a property is seldom used or not very useful through the IDE then just place the [Browsable(false)] attribute on it.
Second:
If you really want all properties to be visible in the IDE properties window, but want to give individuals a way of hiding the more advanced (or less used) ones, just throw them all in an 'Advanced' category. The user can then simply collapse that category and forget about them.
Also: Take a look at Oliver's answer to this question:
[how-to-show-or-hide-properties-dynamically-in-the-propertygrid]
I'm not sure to understand what you are trying to achieve.
When you use Attributes, those are static to the class. So, in your case, when you toggle a show/hide on an object, it's on an instance of the object. Also, you cannot change an attribute value at run-time.
Maybe you should try an alternate solution like creating a global
map<pair<type of object, property name>, is shown>
and update that accordingly from your editor.
And if you want to use something like a property grid, you will have a problem since it won't check your map, but it can be fixed. You could create a new class at run-time and make it a proxy to your current instance. (check on the net how to achieve that, but it's quite simple. There are 2 possibilities: compile from a string or use the ILGenerator.
Hope this help.
I have a need to provide as options multiple objects from a particular data set, and populate a list so that an end-user can select, none,some, all, or all + possibly missing data fields (user-input).
I originally planned to extend a System.Windows.Forms.ListView to include a whitespace item that contained a checkmark, then specially handle the case where a user had clicked this blank line item.
I would like the ability to remove these user-input line items if possible. I do not have to use a System.Windows.Forms.ListView, but its design seems to best-fit this particular use.
Is there a control with this functionality already , or an attribute of the System.Windows.Forms.ListView I have missed that may handle these situtations?
---Update---
ListBox is changed to System.Windows.Forms.ListView
DataGrid sounds like it would be a good fit; otherwise I'd suggest looking at 3rd party controls.
I need a search panel similar to the findpanel in devexpress. FindPanel is a bit slow: it searches all the visible columns and removes the not-fitting-the-description rows from the xtragrid. If you know a way to override these unwanted behaviors or another component that does the same job without the previous behaviors please do share. If not...
I need to create a panel, with one textedit, and two simplebuttons in it. And since I am going to use this same component with different xtragrids over and over again, I need to make it a standalone component, and be able to point towards the xtragrid from the properties window. As if its a standard component.
So how do I do that ? If you have an entire example project it would be perfect, but if not, I am just looking for some pointers.
Thank you...
There is a property to specify a list of columns for search by: ColumnViewOptionsFind.FindFilterColumns Property
You also can create a standalone user control with the public GridView property. This property allows you to select GridView instances in the designer. To apply the search expression programmatically, use the ColumnView.ApplyFindFilter Method
In my application, different controls are only used dependent of the values of properties from a particular object. The forms constructor accept this object as a parameter.
The form has always some basic functionality, no matter what properties are set of the particular object.
Now I have something like this:
if(myObject.SomeProperty)
{
myControl.Visible = true;
myOtherControl.Visible = false;
// and so on
}
At this time, the controls that are dependant of SomeProperty are buttons and tab items. However, I can imagine that in the future other controls are added to the form and are also dependant of SomeProperty.
As you might guess, I want to set this up the right way. But I don't know exactly how. How would you implement this?
There are multiple ways I can think of solving this, depending on your situation you could select the best suited to you.
1. Databinding is one elegant solution when managing the state (visibilit or other properties) of multiple control's depend on a different object. Additional details in this question
2. You could write different functions if the combination of the states is only limited to couple of cases to at most 4-5 cases. That ways you can still reason about the methods which set the state depending on the object you are depending on. Ex: Basic_Editing, Advaced_Editing, Custom_Editiong etc.
3. If the number of cases are limited you could create multiple forms (User controls) and load them on demand based on the state of the dependent property (or object you are talking about).
Just having a bunch of if else's makes your code harder to maintain, or comprehend, logically group the states so that 1. You could reason about it later, 2.Someone else understands the reason/logic 3.When there is a change required it can be localized to one of these modular methods (techniques) reducing the time to fix, and test.
I would do it like this in form constructor:
myControl.Visible = myObject.SomeProperty && !myObject.SomeOtherProperty;
myOtherControl.Visible = !myObject.SomeProperty;
....
Is it the less code and its rapidly changing.
OR
You can create separate functions that will generate controls dynamically at runtime for each form view based on object properties.
First i can see you are setting visibility on/off it means you have already controls on the form every time.. , so that not a good practice, instead create controls only when needed.
As for your scenario you can have an function like Initialize() which contains all the code for checking if showing a particular control should be shown or not and then create it and add it to Forms control collection. If any new control come to be added later you have one function to update.
A more precise answer can be given if you can provide more detail to you scenario
