Question

I created the new form1 the Equipment - includes fields - type, vendor, model, serial number, the status etc. I create other form2  in which also is  type, model of the equipment etc. Prompt, please, an operations procedure to relate this fields. The user chooses Type, the vendor who corresponds to the chosen type, model. Serial number already it is populated automatically from the equipment form1. How such binding to realize?

Answer 1

Hi,

 

I hope I am understanding your issue properly. When the user searches on form1 could you not save the search criteria in a struct etc and then when you are opening the second form you pass in this struct in the constructor (of form2). Then you have all the details the usser entetred in form1 to correctly configure form2.

hope this helps?

Answer 2

I want to field in the form2 have been linked with other fields of Equipment CI (form1). When filling out the properties (on form2) of the type, vendor, model, other properties-serial number,inventory number etc are populated automatically.

Answer 3

Hi,

 

Okay I get you. you won't be able to do this with binding in xaml because they are 2 seperate forms. Instead what you can do is if a combo box selected item changes in form1 you can pass the data to the the second window by using the following code -

 

//This line will give you a handle to your form2 screen 

form2 formTwo = App.current.MainWindow as Form2.

//pass in selectedvalue from combo box (in form1) to public method on form2

formTwo.PublicMethod(string comboval);

Then in this public method (of form2) you can repopulate all the controls according to the criteria. 

 

does that make sense?

 

Answer 4

Can make a method that will be choose the condition data (serial number, inventory number etc) about equipment when changing field model,type,vendor ?

I created a form Equipment for data entry and  new class for Equipment, which has the properties: type, vendor, etc. This form is stored. The user must open another form and it when choosing the type, model, other fields are filled in automatically.

Answer 5

Hi PufikYS,

The way Pritesh has mentioned above should be a way to obtain what you are trying to achieve.

You can expose a method on the second form to pass in the parameters that you require from the first form and call it whenever necessary.

Kindly let know if you are facing any issues using that approach.

Providing a sample code of what you are currently doing would make it more easier to help you out.

Answer 6

Thanks!!! I'll try!

Answer 7

Yeah Rahul is correct. I'm a little confused by what you are trying to achieve so I'm not sure if I'm providng you with the right solution.

Here what I think you want to do - 

If you have the employee classs with the values set from form1 then you can pass that employee class to form2 as a parameter in a method and then using its values form2 can determine how to configure itself.

 

Is this what you want to happen?

Answer 11

Okay thanks for the update. 

 

So how I would choose to do it is to pass in the information via the constructor to Window1 -

 

private void button1_Click(object sender, RoutedEventArgs e)
  {
   Window window = new Window1(string selectedComboVal);
   window.WindowStartupLocation = WindowStartupLocation.CenterScreen;
   window.Show();

}

You could pass in something other than a string e.g. a struct or class containing all the information the user filled in the MainWindow

Then in window1 you could have a method that does the populating of its fields

 

something like this - 

 

 public Window1(string comboVal)

 {
	
  InitializeComponent();

 PopulateFeilds(comboVal);

}

private void PopulateFeilds(comboVal)

{

//Populate fields in here

}

Answer 12

Hi,

The above way of doing this through the constructor is one way of doing.

Since in WPF all the controls are with parameterless constructors , I would suggest you to define a method in your Window1 class and do the same by invoking the method.

Modifying the above code:

 

 public Window1()

 {

 InitializeComponent();
}

public void PopulateFeilds(comboVal)
{
//Populate fields in here
}

private void button1_Click(object sender, RoutedEventArgs e)
 {
 Window window = new Window1();
 window.WindowStartupLocation = WindowStartupLocation.CenterScreen;
 window.PopulateFields("Your Data");
 window.Show();
}

 

Feel free to ask if you need more help on this

Answer 13

What is the comboVal? and how Populate feilds? Thanks!

Answer 14

Hi,

 

My example doesn't fit your problem exactly. 

 

But heres a slighlty different example -

 

Type

private void button1_Click(object sender, RoutedEventArgs e)
 {
  Window window = new Window1(string Typr);
  window.WindowStartupLocation = WindowStartupLocation.CenterScreen;
  window.Show();

}

public Window1(string comboVal)

 {
	
 InitializeComponent();

 PopulateFeilds(type);

}

private void PopulateFeilds(type)

 

{

 //Populate fields in here

label1.Content = type;

}

 

I hope that makes more sense?

Answer 15

This code in the MainWindow.xaml.cs?

private void button1_Click(object sender, RoutedEventArgs e)
 {
 Window window = new Window1(string Type);
 window.WindowStartupLocation = WindowStartupLocation.CenterScreen;
 window.Show();

}

This in Window1.cs?

 

public Window1(string comboVal)

 {
	
 InitializeComponent(); PopulateFeilds(type);}
private void
PopulateFeilds(type) 
 

{

 //Populate fields in here

label1.Content = type;}

 

Answer 16

Hi,

 

yes  but change this line - 

 

public Window1(string comboVal)

to 

public Window1(string type)

Answer 17

Error then I change line to Window window = new Window1(string Type);

Answer 19

error  'System.Type' is a 'type' but is used like a 'variable' 

Answer 20

The reason your getting this error is becuase you have a public property named Type but that is a reserved word in C#.

 

change the name of the public property Type to something else and then it should work.

 

something like this - 

 

// Public properties.
   public string Type
   {
    set
    {
     strType = value;
     OnPropertyChanged("Type");
    }
    get { return strType; }

to 

// Public properties.
   public string StrType
   {
    set
    {
     strType = value;
     OnPropertyChanged("StrType");
    }
    get { return strType; }

Then change this line - 

Window window = new Window1(Type);

 

to 

 

Window window = new Window1(strType);

Answer 21

Yes, thanks! I changed the name of the public property Type. And this code changing too? 

public Window1(string type)

{

InitializeComponent(); PopulateFeilds(type);}
private void
PopulateFeilds(type)


{

//Populate fields in here

label1.Content = type;

}

Answer 22

for now you can leave that as is. You can rename the type to strType but it should work even if you leave it "as is".

 

does it do what you require?

Answer 23

 private void PopulateFeilds(type) 

Identifier expected

Answer 24

so what do you think the problem is here now? 

 

I could give you the answer but I think its better for you (if you want to learn) that you try to resolve this particular  issue yourself?

Answer 25

Yes, but I don't understand what is the PopulateFeilds(type) ?

Answer 26

Its a method. Look into how you pass in parameters to a method

Answer 27

to declare a method with parameters: static void MethodWithParameters(int n, string y)

public Window1(string type)

{

InitializeComponent(); PopulateFeilds(type);}
private void PopulateFeilds(type)  - it's a method


{

//Populate fields in here

label1.Content = type;

}

Answer 28

Okay basically you just need to add string to the parameter - 

 

private void PopulateFeilds(string type)

 

I hope you didnt think I was messing you around earlier. I think that if you look up issues yourself you learn something rather than someone force feeding you the answers.

Answer 30

We have alrweady dealt with this problem previously. 

 

in mainwindow you cannot use Type as a public property it is a a reserved word which is why you are getting this error. I thought you changed this so that the public property would be called Types or StrType?

Answer 31

Why the label1.Content = type ?

Answer 32

Okay,

 

I thuoght you wanted the user to complete some text fields (in the Mainform). Then when they cluick the button the second form (Window1) is displayed with the values they entered prepopulated.

'

so Label "Type" has the value the user entered in the textfield (on mainform). This is what I thought you meant by prepopulated?

Answer 33

Yes, but my LabelName and combobox is empty

Answer 34

You should be able to modify the code so that the fields gets prepopulated. Using what you already have, pass in extra parameters in the constructor of Mainform.

 

As for the combo box, is it already propluated with items? Or is it empty? 

Answer 35

In the Mainform I have 3 textBoxes - name, vendor, serial number. User must fill in these fields. In Window1 I have 2 combobox and 1 textbox. When user click button - open Window1, user click to combobox name, vendor and choose the item. Serial number populate automatically.

Answer 36

so then this is quite simple, I told you to pass in Type (which is now StrType or Types) but instead pass in the value from serial number and then 

 

 

private void button1_Click(object sender, RoutedEventArgs e)
 {
  Window window = new Window1(txtSerialNum);
  window.WindowStartupLocation = WindowStartupLocation.CenterScreen;
  window.Show();

}

Then you window1 code should look like - 

public Window1(string serialNum)

{

InitializeComponent(); PopulateFeilds(serialNum);}

private void PopulateFeilds(string serialNum) 


{

//Populate fields in here

txtSerialNum.Text = serialNum;

}

 

and then your done

Answer 37

Window window = new Window1(txtSerialNum);
Argument 1: cannot convert from 'System.Windows.Controls.TextBox' to 'string' 

Answer 38

change to 

Window window = new Window1(txtSerialNum.Text);

Answer 39

Yes! it's work, but user must choose a name and a vendor from the list (in combobox) that wrote in the Mainwindow, after that serial number populate auto.

Answer 40

I give up. Maybe someone else can help you.

 

I don't know what you want and you are not that good (unfortunatly) at explaining yourself.

you keep talking about prepopulating but now you are saying this is incorrect and you need something different.

 

Maybe someone else on here can help you achieve your goal

Answer 41

Now, serial number automatically filled in immediately. User must choose items from combobox (this items he input on form Mainwindow) after that serial number populate auto. Ok?

Answer 42

Okay i think I'm getting you but you are going to have to answer some questions about this -

 

If I select an item in the combobox, where are you getting the serial number from? e.g. are you retrieving the serial number from a database etc.

 

Secondly can you post your code behind for MainWindow?

Answer 43

Is there a whole project being done here :)

Lets make all the questions crisp and clear so that everyone benifits.

PufikYS could you list down what exactly you are trying to achieve and what problems that you are facing.

Answer 44

In MainWindow have 3 text boxes-Name,vendor, serial number. The user enters the data in these fields.
The data from the fields Name, Vendor must fall within the drop-down list on the form of Window1.
After selecting the data (name and vendor) by user, Serial Number field is automatically filled. Ok?

Answer 45

I understand that this is your requirement.

Kindly detail out the problem that you are facing now in implementing this
