[Edited Version based on replies]
I would like the button1 to be enabled only if both textbox and datetimepicker are filled. I am able to do for the text but not for datetimepicker. Here is my full code. FYI: my datetimepicker is being formatted to empty initially to allow user to choose a date himself.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Inspection
{
public partial class Vdetails : Form
{
public Vdetails()
{
InitializeComponent();
Vnew.Enabled = false;
}
//Allow user input date
private void DTafes_ValueChanged(object sender, EventArgs e)
{
DTafes.CustomFormat = #"";
}
private void DTfa_ValueChanged_1(object sender, EventArgs e)
{
DTfa.CustomFormat = #"";
}
private void DTfe_ValueChanged(object sender, EventArgs e)
{
DTfe.CustomFormat = #"";
}
//Condition to allow button to go next
private void ActivateButton()
{
Button1.Enabled = (Vehicle.Text != "" && Distance.Text != "");
}
private void Vehicle_TextChanged(object sender, EventArgs e)
{
ActivateButton();
}
private void Distance_TextChanged(object sender, EventArgs e)
{
ActivateButton();
}
}
What and how do I add the code to allow for datetimepicker to be filled. Hope that someone could help me.
The dateTimePicker has no textchanged-event. There will never be an empty string inside the dateTimePicker. (Maybe you can set it via code, but not by user-input) You can use the valueChanged-event of the dateTimePicker to do something when the date was changed by the user.
Since the text will never be empty, you dont have to check it in you ActiveButton-function.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void ActiveateButton()
{
this.button1.Enabled = textBox1.Text != string.Empty;
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
ActiveateButton();
}
private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{
ActiveateButton();
}
}
DateTimePicker is always got a value but you can listen to the ValueChanged event
private bool dateChanged;
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
dateChanged = false;
button1.Enabled = false;
}
private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{
dateChanged = true;
SetEnabledness();
}
private void SetEnabledness()
{
button1.Enabled = !string.IsNullOrWhiteSpace(textBox1.Text) && dateChanged;
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
SetEnabledness();
}
If you have more than one DateTimePicker you can use a HashSet instead of a bool (just make sure you wire up all the ValueChangedEvents to dp_ValueChanged e.g.
private HashSet<DateTimePicker> dateChanged = new HashSet<DateTimePicker>();
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
dateChanged.Clear();
button1.Enabled = false;
dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker2.Format = DateTimePickerFormat.Custom;
dateTimePicker3.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = #" ";
dateTimePicker2.CustomFormat = #" ";
dateTimePicker3.CustomFormat = #" ";
}
private void dp_ValueChanged(object sender, EventArgs e)
{
var dp = (DateTimePicker) sender;
dp.Format = DateTimePickerFormat.Short;
dateChanged.Add(dp);
SetEnabledness();
}
private void SetEnabledness()
{
button1.Enabled = !string.IsNullOrWhiteSpace(textBox1.Text) && dateChanged.Count == 3;
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
SetEnabledness();
}

I want to access the latest checkstates and the latest set date value using a function called GetProfileFilter. Now my problem is I'm not able to fetch the latest values when either the checkbox.Checkstate is changed or the datetimepicker is changed.I'm setting the values based on whether the checkboxes are set and I intend to use the IBitWise value elsewhere.Note that at form load all the checkboxes are checked.In the form class I have nothing more than a few variable and the event handlers for buttons and checkboxes and date time pickers.Open to all suggestions!!
class Profile{
public bool GetProfileFilter()
{
if (frmInactive.btnApplyWasClicked == true || frmInactive.btnCancelWasClicked == false)
{
frmInactive.ShowDialog();
MessageBox.Show("Here");
if (frmInactive.chkCancel.Checked == true)
{
MessageBox.Show("Cancel");
IBitWise += Canceled;
}
if (frmInactive.chkDiscon.Checked == true)
{
MessageBox.Show("Discon");
IBitWise += Discontinued;
}
if (frmInactive.chkVoidwoRes.Checked == true)
{
MessageBox.Show("Voidedwo");
IBitWise += VoidedWoutRes;
}
if (frmInactive.chkVoidwRes.Checked == true)
{
MessageBox.Show("Voidedw");
IBitWise += VoidedWRes;
}
MessageBox.Show("Ibit value:" + IBitWise);
return true;

I have these textboxes named bags,rate,quantity,packing size and amount what i want to do is that when user enters bags and rate and packing size the quantity textbox should automatically shows the corresponding quantity and amount but in my case when i click on calculate button then it calculates and show the quantity and amount i have tried using textchanged event but it does not do the job?

Normally "TextChanged" event fires autamatically if text value changes.
So here the problem is i think about your other "partial class" in which there has to exist eventhandler work. Something like:
txtBags.TextChanged += new EventHandler(txtBags_TextChanged);
Please check your other partial class if this staement exist.
This eventhandler sometimes disappears from project if you move your gui elements or for some other causes...
You can readd this statement manually.
By the way if you have not experience with the other partial class then you can try to remove these textboxes and re-add them then your problem will autamatically solves.
You need to call DisplayAmt in the TextChanged event of txtBags , txtRate and Size. In the code above, call to DisplayAmt is commented out. Instead, you are calling DisplayAmt in the TextChanged event of txtQty.
You should be, instead doing.
private void txtAmt_TextChanged(object sender, EventArgs e)
{
DisplayAmt();
}
private void txtRate_TextChanged(object sender, EventArgs e)
{
DisplayAmt();
}
Similarly, you need to add Changed event for Text Control for Size. The txtQty is updated by the DisplayAmt() method. So you don't necessarily need it, unless for reasons that are not specified in OP.
I have been trying to make a menu which has 3 tabs. Login, News and website. I created user control and named it LoginTab.cs now I put the login panels in there LoginTab.cs, NewsTab. Now I am trying to make it visible and invisible depending on what tab people click. So if someone clicks news then the LoginTab goes away and shows the News tab. My problem is that I can't used LoginTab.Visible because its showing me "Cannot access non-static property 'Visible' in static context. How would I do this?

Do the same for other textBoxes, you should use TryParse and also use 1 TextChanged event handler for all the textBoxes.
The following code uses TryParse and suppose if the parsing fails, the default value will be 0:
private void textBox1_TextChanged(object sender, EventArgs e){
int v;
if(int.TryParse(textBox1.Text, out v)){
aOrder.numberOfPizzas = v;
} else aOrder.numberOfPizzas = 0;
}
Either use TryParse as suggested by other answers or place 0 for text boxes used for numeric input in your clear method. Another approach is to use MaskedTextBox for text boxes used for numeric input.
Here you can use the manual method as well. Write the following code inside your button click function,
if (textBox1.Text != string.Empty || textBox2.Text != string.Empty || textBox3.Text != string.Empty || textBox4.Text != string.Empty || textBox5.Text != string.Empty || textBox6.Text != string.Empty)
{
textBox1.Text = "";
textBox2.Text = "";
textBox3.Text = "";
textBox4.Text = "";
textBox5.Text = "";
textBox6.Text = "";
}
I have an app that has 3 text boxes, (users name, what company they are from, and who they are visiting) A button to print, and a keyboard on the screen (monitor is touch screen). I have everything working and functioning...
BUT, the one thing that does not work is when the user points to previous character in the text box that has already been typed, the buttons that "AppendText" (keyboard) do not start typing where the user pointed but it continues typing at the end of what has been typed.
Is this because of "AppendText" or some other issue that I have in my code?
I also am trying to get the first text box (Name_Box) to be sent to form one, which then will be split into two labels (1, first name| 2, last name) right now I have it being sent to one label But I want to split it so the first name is stacked above the second name in the next form (which is printed out).

You're right in that your problem is the use of AppendText, which always appends to the end (that's what append means).
You need to Insert the character at the current carat position.
You might do better to post a message that simulates a keypress from a physical keyboard.
If you want to insert text at the user's current position, you can use SelectedText. This will replace the current selection (if the user has selected characters):
tbSelected.SelectedText = "V";
Edit: The problem is in here:
private void button24_Click(object sender, EventArgs e)
{
//DELETE
string t = tbSelected.Text;
if (t.Length > 0)
{
tbSelected.Text = t.Remove(t.Length - 1);
}
}
You set the text, which returns the cursor to the beginning of the textbox. You should set tbSelected.SelectionStart after you clear the text.
