I got problem with ComboBox in winforms c#. Comboboxes in main window works fine, but comboboxes in form that I open in panel on main window are broken. The wierd things starts to happen... I cant click it to type. I can only open list, select one and then type. Also i cant locate cursor in the middle of text because it highlight whole text. I post code with I open form in panel:
public void otworzOkno(Form _form)
{
if (Application.OpenForms[_form.Name] != null)
{
Application.OpenForms[_form.Name].WindowState = FormWindowState.Normal;
Application.OpenForms[_form.Name].BringToFront();
}
else
{
_form.TopLevel = false;
_form.AutoScroll = true;
this.panel.Controls.Add(_form);
_form.Show();
_form.BringToFront();
}
}

how have you constructed the comboboxes?
do they have an assigned datasource?
do they share datasources?
how you are showing the way that you are opening the form that they are on doesn't show the problem it's on that form.

The problem is that the form is opened in panel, because when i open the same form with the same settings in seperate window not in panel it works fine. I dont know why that happen

as a Test I would change your code to this, I do something similar but I use a splitter container.
public void otworzOkno(Form _form)
{
if (Application.OpenForms[_form.Name] != null)
{
Application.OpenForms[_form.Name].WindowState = FormWindowState.Normal;
Application.OpenForms[_form.Name].BringToFront();
}
else
{
_form.TopLevel = false;
_form.Parent = panel;
_form.Show();
_form.BringToFront();
}
}

Still the same, even when I tried in SplitContainer ;/

you then need to show how the combo's are generated and populated.

I create it in visual studio (from toolbox) and even empty comboboxes with default settings, no code, just draged and droped has the same behaviour.
|

..which is tucked away in a method called "InitializeComponent". That method is called when the form is created. Hiding the form and showing it won't execute the method again. Yes, that may cause weird stuff.
I'd recommend showdialog a form and disposing it when done, preferably wrapped in a using-construct.

foxed fixed typo.

Yeah exaclty. But when form is open in panel i can only click on blue site (http://postimg.org/image/lalx7hu9x/[^]) to write and cant edit text like in my movie. when i open the same form as new form i can click on blue and red site to start typing. In your solution is the same problem and its very annoying. Btw thank you for your help and involvement

Sorry stupid mistake, for this to work you have to change the border style of the form with the comboboxes to none.

I added some code:
private void cbProducent_MouseClick(object sender, MouseEventArgs e)
{
if(cbProducent.Text == "")
{
cbProducent.Focus();
}
}
still cant click to writte in middle of text but it solves problem with blue and red sites ;D

Don't use Forms inside any other ContainerControl. Use UserControls, or Panels. Forms are "expensive" UI-components, and they do not play well used inside other Forms/Controls.

 hi,
I need to explain a video about design algorithm
id3 ,please how can help me??
|
|
|
|
|
We can't.
We have no idea what your video is showing (and to be honest I have no desire to see it) - so how could we possibly help you explain it?

There algorithm in C # called id3 I need to explain how it works and this algorithm
؟ 
|
|
|
|

Well then, YOU better get to studying how it works otherwise YOU are not going to be able to explain it.
Nobody here can hit you with a magic wand to implant the knowledge in your head. This is where YOU start studying whatever you can find on it and start making your own diagrams. Searching the net for somoe premade video that may not even exist is just wasting your time.

Oh. It's your homework.
I see now - you want us to point you at a video you can fast forward through, writing down random words in the hope it might get you a passing grade?
It won't. You need to understand it.
Start here: https://en.wikipedia.org/wiki/ID3_algorithm[^]
But don't just copy it: your tutor will notice. You need to learn, understand and describe it in your own words...

dear respectabls i m developing a project in which i need to retrieve data on click event from same row where dynamic picture is located...
keep in mind at every click event there may b different number of dynamic pictures, each have different detail in d.b/ plzzzz ans me as well as soon..

Do not post the same question in multiple places: you already have this in QA, and have for nearly an hour, so leave it there. Posting the same thing in multiple places duplicates work, and that wastes our time and annoys people.
And read my comments on your question there - you have just posted the same text here and hoped we would magically divine what you need.

So, you hook up the click event of the control you generated.

Also keep in mind that the db might move, or get renamed; that info has to be updated easily without the need of a recompile. I'm sorry, but this is not even an assignment; it is a rough outline of a users' wishes. It is also not a complicated request, so I'm wondering what your question is.
