C# how to filter items on ListView using textBox

I want to filter the items that I added to my Listview, using my textbox_TextChanged Can you please show me the Codes, I am using Visual Studio 2013. tia
e.g.
First I am adding a Destination/Regularfare/Discountedfare/Baggagefare to my ListView. and my problem is Searching I want to search the Destinations using a TextBox.
There are no Codes inside my TextBox Search. that one I need.
And here's my Codes for adding an item to my ListView.
public void add(String destination, String Regulare, String Discounted, String Baggage) {
String [] rows = { destination, Regulare, Discounted, Baggage};
ListViewItem item = new ListViewItem(rows);
listView1.Items.Add(item);
}
private void btnAdd_Click(object sender, EventArgs e) {
add(textBox1.Text, textBox2.Text, textBox3.Text, textBox4.Text);
textBox1.Text = "";
textBox2.Text = "0";
textBox3.Text = "0";
textBox4.Text = "0";
MessageBox.Show("Record Added!","Saved",MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
tbDestination.Focus();
}

Like the other posters were saying, we don't know what your tech stack is or what problem you're trying to solve. Have you tried binding your list to a data source? Let's say you have a text box and a submit button for filtering. The user enters "California" into the text box and presses submit. You'll have a click handler in the code behind that invokes a DataBind() on your list. The method for your data bind will get the value of the textbox/hidden field and use it to return a conditional data structure that is then used to populate your list. You could even have a clear button that resets the filtering using the same method.
But it's been 16 days now, so you've probably already solved the problem. What did you end up doing?

Hı , Try this two way
First :
private void searchBox_TextChanged(object sender, EventArgs e)
{
// Call FindItemWithText with the contents of the textbox.
ListViewItem foundItem =
textListView.FindItemWithText(searchBox.Text, false, 0, true);
if (foundItem != null)
{
textListView.TopItem = foundItem;
}
}
Second :
void yourListView_MouseDown(object sender, MouseEventArgs e)
{
// Find the an item above where the user clicked.
ListViewItem foundItem =
iconListView.FindNearestItem(SearchDirectionHint.Up, e.X, e.Y);
if (foundItem != null)
previousItemBox.Text = foundItem.Text;
else
previousItemBox.Text = "No item found";
}

converting Gridview Code to Listview Code

i'm trying to convert a gridview into a listview. The bit that is troubling me is that i can't get at following codes
TextBox box1 = (TextBox)Gridview1.Rows(rowIndex).Cells(1).FindControl("clientCode");
Please help me to achieve this code in Listview Format.

(TextBox)listview1.Items(rowIndex).FindControl("txtFName")
This is what you want

You can use ItemCommand event of listview to get the text box control which used in List View control
protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
{
if (e.CommandName == "Edit")
{
TextBox txtFname = (TextBox)e.Item.FindControl("txtFname");
}
}

Is this what you want?
TextBox box1 = (TextBox)ListView1.FindControl("clientCode")
get text
box1.Text = ListView1.SelectedItems[rowIndex].SubItems[1].Text;

WPF datagrid column autocomplete

Hello I need a help about datagrid in wpf. Actually I have C# experiences but new in WPF. I can answer my question in c# but don't know how to do this on WPF. I am using this code to solve datagridview cell autocomplete problem in c# and it works very good.
private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if(dataGridView1.CurrentCell.ColumnIndex == 7)
{
AutoCompleteStringCollection acBusIDSorce = new AutoCompleteStringCollection();
acBusIDSorce.Add("Autocomplete Value 1");
acBusIDSorce.Add("Autocomplete Value 2");
acBusIDSorce.Add("Autocomplete Value 3");
TextBox txtBusID = e.Control as TextBox;
if (txtBusID != null)
{
txtBusID.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
txtBusID.AutoCompleteCustomSource = acBusIDSorce;
txtBusID.AutoCompleteSource = AutoCompleteSource.CustomSource;
}
}
}
But I can't see EditingControlShowing Event in Wpf. How can i make this solution in WPF ? I searched many platforms but couldn't find anything
edit: I am populating my dataGrid with codebehind with this code
dataGrid1.ItemsSource=dt.DefaultView;

How to hide a text box with a dynamic ID from another controller event handler?

I have an AddRow() method which generates a check box and a text box for each row in the table, I need to control the text visibility by checking the check box in the same row.
that seemed to be easy for the first while, since I can get the targeted text box ID but I dont know how to do it now.
here is my method:
private void AddRow(int nRowIndex, string strPaymentStatus,string PaymentRemark)
{
// checkBox -----------------------------------------------------------------
CheckBox objCheckBox = new CheckBox();
objCheckBox.ID = strBillID;
objCheckBox.Checked = false;
objCheckBox.CheckedChanged += new EventHandler(cbxPaymentStatus_CheckedChanged);
objCheckBox.AutoPostBack = true;
// textBox----------------------------------------------------------
TextBox objTbxRemark = new TextBox();
objTbxRemark.ID = BillID;
objTbxRemark.AutoPostBack = true;
}
CheckBox handler:
protected void cbxPaymentStatus_CheckedChanged(object sender, EventArgs e)
{
// here I can get the BillID (textBox ID) by a query, but I need to control its visibility from here
}
any help will be appreciated..

You can try to use
Page.FindControl("id")
If you can reconstruct the correct id. They probably follow some kind of pattern based on the parents controls
The you have to cast to TextBox
TextBox txt = Page.FindControl("id") as TextBox ;
txt.Visible =...

Flickring issue in Textbox when using auto complete in c#

i am using custom auto source to the text box. But the problem is, when i am entering key , if the suggestion list is high then the textbox flickers before showing suggestion.
private void txtSearch_TextChanged(object sender, EventArgs e)
{
if (txtSearch.Text != "")
{
string templateSearchTxt = txtSearch.Text;
foreach (String template in templateName) // templateName contains list of string
{
if (template.ToUpper().StartsWith(templateSearchTxt.ToUpper()))
{
suggestion.Add(template);
}
}
}
}
I have declared following code on form load event
suggestion = new AutoCompleteStringCollection();
txtSearch.AutoCompleteCustomSource = suggestion;
txtSearch.AutoCompleteMode = AutoCompleteMode.Suggest;
txtSearch.AutoCompleteSource = AutoCompleteSource.CustomSource;

I will seriously encourage you to use a Combobox with its AutoCompleteMode set to Suggest and attach the autocomplete list to it (as its AutoCompleteSource). It'll performt way better than your textchanged event listener.
