I want to when i'm clicking one item in my list view to send the in a textview
I'm using this code but nothing happens
listview1.ItemClick += listview1_SetOnClickListener;
}
void listview1_SetOnClickListener(object sender, EventArgs e)
{
TextView textview1= FindViewById<TextView>(Resource.Id.PanelCaptionSelect);
ListView listView1 = FindViewById<ListView>(Resource.Id.PanelCaptions);
String list;
list = listView1.SelectedItem.ToString();
textview1.Text = list;
SOLVED!
lvDetail.ItemClick += (object sender, Android.Widget.AdapterView.ItemClickEventArgs e) =>
{
string selectedFromList = lvDetail.GetItemAtPosition(e.Position).ToString();
lbltext.Text = selectedFromList;
};

I have listview that may change text on event like shown :
private void OnEvent(object sender, AutomateConnectionEventArgs e)
{
if (aListView.InvokeRequired)
{
Invoke(new MethodInvoker(delegate()
{
Traitement(e);
}));
}
else
{
Traitement(e);
}
}
private void Traitement(AutomateConnectionEventArgs e)
{
ListViewItem item = aListView.FindItemWithText(e.idAutomate);
if (e.notification.Equals("connect"))
{
aListView.Items[item.index].SubItems[5].Text = DateTime.Today.ToShortDateString();
aListView.Items[item.index].SubItems[7].ForeColor = Color.Green;
aListView.Items[item.index].SubItems[7].Text = "Connected";
aListView.Items[item.index].SubItems[8].Text = DateTime.Now.ToLongTimeString();
}
}
It's rise no error and when follow this with breakpoint in visual studio it's run correctly but the listview won't change the text in the form
Just Create new ListViewItem object with new values and Update the old ListeviewItem with new ListViewItem object.
I have two ListBoxes. I want to copy SelectedItem from the first ListBox into Second one.
Why this code does not work ?
private void frm_addDispatchBoard2_Load(object sender, EventArgs e)
{
using(propertiesManagementDataContext db = new propertiesManagementDataContext())
{
var Buildings = db.Buildings.Select(q => new { q.BuildingLandNumber, q.BuildingId });
listBox_allBuildings.DataSource = Buildings;
listBox_allBuildings.DisplayMember = "BuildingLandNumber";
listBox_allBuildings.ValueMember = "BuildingId";
}
}
private void btn_addBuilding_Click(object sender, EventArgs e)
{
if(listBox_allBuildings.SelectedIndex > 0)
{
listBox_selectedBuildings.Items.Add(listBox_allBuildings.SelectedItem);
}
}
The result I got:
try this I am not sure why you are looking for a Contains but if you really need that look at the difference between SelectedValue and SelectedItem
Use this code right here as a test to see if the expected value shows up in a MessageBox
string selected = listBox_allBuildings.GetItemText(listBox_allBuildings.SelectedValue);
MessageBox.Show(selected);
this should help you to see the values in the Listbox on the right
private void btn_addBuilding_Click(object sender, EventArgs e)
{
if(listBox_allBuildings.SelectedIndex != -1)
{
var selected = listBox_allBuildings.GetItemText(listBox_allBuildings.SelectedValue);
listBox_selectedBuildings.Items.Add(selected);
}
}
I have been working on this project for a few days, it’s a C# Windows Visual Studio 2010 form and I have been posting different questions that relate to the same project; as I was told to post different questions instead on having them all in the same post. So this is the project: create a form with two ListBoxes—one contains at least four font names and the other contains at least four font sizes. Let the first item in each list be the default selection if the user fails to make a selection. Allow only one selection per ListBox. After the user clicks a button, display "Hello" in the selected font and size.
This time I’m having a problem getting the message in the textbox to display according to the font type and size that the user selected. Here is where I’m at in the coding:
public Form1()
{
InitializeComponent();
//populate listbox1
listBox1.Items.Add("Arial");
listBox1.Items.Add("Calibri");
listBox1.Items.Add("Times New Roman");
listBox1.Items.Add("Verdana");
//populate listbox2
listBox2.Items.Add("8");
listBox2.Items.Add("10");
listBox2.Items.Add("12");
listBox2.Items.Add("14");
this.listBox1.SelectedIndexChanged += new System.EventHandler(this.listBox1_SelectedIndexChanged);
listBox1.SelectedIndex = 0; // <--- set default selection for listBox1
this.listBox2.SelectedIndexChanged += new System.EventHandler(this.listBox2_SelectedIndexChanged);
listBox2.SelectedIndex = 0; // <--- set default selection for listBox2
}
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
textBox1.Text = listBox1.SelectedItem.ToString();
}
private void listBox2_SelectedIndexChanged(object sender, EventArgs e)
{
textBox1.Text = listBox2.SelectedItem.ToString();
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
textBox1.Text = "Hello!";
}
private void button1_Click(object sender, EventArgs e)
{
}
}
}
Now I'm trying to elicit a call from a button clicked that will display the message "Hello" in the user’s choice of font and font size. Any suggestions would be greatly appreciated.
remove this method:
private void textBox1_TextChanged(object sender, EventArgs e)
{
textBox1.Text = "Hello!";
}
in the button_click event of your button, add this :
private void button1_Click(object sender, EventArgs e)
{
textBox1.Text = "hello";
textBox1.Font = new Font(listBox1.SelectedItem.ToString(), Convert.ToInt32(listBox2.SelectedItem.ToString()));
}
you might want to remove the selectedindexchanged methods in your code if you are going to use a button tho. depends on what you want.
edit:
public Form2()
{
InitializeComponent();
listBox1.Items.Add("Arial");
listBox1.Items.Add("Calibri");
listBox1.Items.Add("Times New Roman");
listBox1.Items.Add("Verdana");
listBox2.Items.Add("8");
listBox2.Items.Add("10");
listBox2.Items.Add("12");
listBox2.Items.Add("14");
listBox1.SelectedIndex = 0;
listBox2.SelectedIndex = 0;
}
private void button1_Click(object sender, EventArgs e)
{
textBox1.Text = "hello";
textBox1.Font = new Font(listBox1.SelectedItem.ToString(), Convert.ToInt32(listBox2.SelectedItem.ToString()));
}
if you just use the above code everything should work as you want it to. I tried it out myself and it's working fine for me
This was my final submission. Thanks for all of the advice guys.
public Form1()
{
InitializeComponent();
//populate listbox1
listBox1.Items.Add("Arial");
listBox1.Items.Add("Calibri");
listBox1.Items.Add("Times New Roman");
listBox1.Items.Add("Verdana");
listBox1.SelectedIndex = 0; // <--- set default selection for listBox1
//populate listbox2
listBox2.Items.Add("8");
listBox2.Items.Add("10");
listBox2.Items.Add("12");
listBox2.Items.Add("14");
listBox2.SelectedIndex = 0; // <--- set default selection for listBox2
}
private void button1_Click(object sender, EventArgs e)
{
textBox1.Text = "hello";
textBox1.Font = new Font(listBox1.SelectedItem.ToString(), Convert.ToInt32(listBox2.SelectedItem.ToString()));
}
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
}
private void listBox2_SelectedIndexChanged(object sender, EventArgs e)
{
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
}

I am using DevExpress in my winform application, I have a gridview, data entry form, datanavigator, all bound to dataset.
I want to add new record, if using datanavigator "Add" it works good, how to do the same using a "New Record" button?
BindingSource.AddNew()
is not working, it usually does, but with devexpress its not working.
If you want to use binding then use your objects with binding source..
and use the binding list .AddingNew += new AddingNewEventHandler(listOfParts_AddingNew);
event to add new entity object ..
See the example of BindingList on MSDN.
void listOfParts_AddingNew(object sender, AddingNewEventArgs e)
{
e.NewObject = new Part(textBox1.Text, int.Parse(textBox2.Text));
}
DevExpress WinForm Controls works so fast with binding sources as compare to typed datasources etc... YOu can implement bindingSources using these example..
set gridview and the associcated controls datasource to bindsouce that you have created...
process your form with the this MSDN example..
have a look on this code snippet.. may be you will get some idea from this..
private void BindingLIstDemo_Load(object sender, EventArgs e)
{
InitializeListOfEmployees();
BindlstEmp();
listofEmp.AddingNew += new AddingNewEventHandler(listOfEmp_AddingNew);
listofEmp.ListChanged += new ListChangedEventHandler(listofEmp_ListChanged);
}
private void BindlstEmp()
{
lstEmpList.Items.Clear();
lstEmpList.DataSource = listofEmp;
lstEmpList.DisplayMember = "Name";
}
void listofEmp_ListChanged(object sender, ListChangedEventArgs e)
{
MessageBox.Show(e.ListChangedType.ToString());
//throw new NotImplementedException();
}
//declare list of employees
BindingList<Emp> listofEmp;
private void InitializeListOfEmployees()
{
//throw new NotImplementedException();
// Create the new BindingList of Employees.
listofEmp = new BindingList<Emp>();
// Allow new Employee to be added, but not removed once committed.
listofEmp.AllowNew = true;
listofEmp.AllowRemove = true;
// Raise ListChanged events when new Employees are added.
listofEmp.RaiseListChangedEvents = true;
// Do not allow Employee to be edited.
listofEmp.AllowEdit = false;
listofEmp.Add(new Emp(1, "Niranjan", 10000));
listofEmp .Add (new Emp (2,"Jai", 8000));
}
// Create a new Employee from the text in the two text boxes.
void listOfEmp_AddingNew(object sender, AddingNewEventArgs e)
{
e.NewObject = new Emp (Convert.ToInt32(txtId.Text), txtName.Text,Convert.ToInt32(txtSalary.Text));
}
private void btnAdd_Click(object sender, EventArgs e)
{
Emp empItem = listofEmp.AddNew();
txtId.Text = txtName.Text = txtSalary.Text = "";
}
private void button1_Click(object sender, EventArgs e)
{
Form1 obj = new Form1();
obj.Show();
}
private void btnDelete_Click(object sender, EventArgs e)
{
var sg = (from sc in listofEmp.ToList<Emp>() where sc.Name == ((Emp)lstEmpList.SelectedValue).Name select sc);
}
private void lstEmpList_SelectedIndexChanged(object sender, EventArgs e)
{
Emp se = listofEmp[lstEmpList.SelectedIndex];
txtId.Text = se.Id.ToString();
txtName.Text = se.Name;
txtSalary.Text = se.Salary.ToString();
}
Here I am using BindingList as datasouce BindingList<Emp> listofEmp; and on the place of grid listing of records are shown in a listbox control.. but all same...try this with your gridview..
I want to move items back and forth between a ComboBox and a ListBox using C# 2010 (form)
My code seems to work. However, when I move the items back to the ComboBox (from the ListBox) I have a space in between the items. If anyone has a suggestion on how to remove the space between the items in the ComboBox I would greatly appreciate it.
private void stateslistcomboBox_SelectedIndexChanged(object sender, EventArgs e)
{
stateslistBox.Items.Add(statescomboBox.SelectedItem);
statescomboBox.Items.RemoveAt(statescomboBox.SelectedIndex);
}
private void stateslistBox_SelectedIndexChanged(object sender, EventArgs e)
{
string item = "";
item = Convert.ToString(stateslistBox.SelectedItem);
statescomboBox.Items.Add(item);
stateslistBox.Items.Remove(stateslistBox.SelectedItem);
}
The statescomboBox.Items.Add(item); triggers Another SelectIndexChanged that adds an empty item.
Try
private void stateslistBox_SelectedIndexChanged(object sender, EventArgs e)
{
string item = "";
item = Convert.ToString(stateslistBox.SelectedItem);
statescombobox.SelectIndexChanged -= stateslistBox_SelectedIndexChanged;
statescomboBox.Items.Add(item);
statescombobox.SelectIndexChanged += stateslistBox_SelectedIndexChanged;
stateslistBox.Items.Remove(stateslistBox.SelectedItem);
}
alternatively, you can prevent empty items being added.
private void stateslistBox_SelectedIndexChanged(object sender, EventArgs e)
{
string item = "";
item = Convert.ToString(stateslistBox.SelectedItem);
if (!string.IsNullOrEmpty(item)
{
statescomboBox.Items.Add(item);
stateslistBox.Items.Remove(stateslistBox.SelectedItem);
}
}
