How to get Dates into Text Boxes from DateTimePicker

Question

Happy New Year Everyone!

 

I am working on an application that I'm building.  I have currently a tablelayout control on my form, along with a date time picker set to select month and year only with up/down selector.

 

I have labels in my table that I would like to basically show the dates of each month as they would on a calendar in my labels.  Any idea how I would do this or do you recommend another approach.  I would like to do it this way because I have other cells in the tablelayout  control that will display collections based on the date.

 

 

Is there an easier way to write this code than in this manner?

 

if (scheduledatepicker.Value.DayOfWeek == DayOfWeek.Sunday)
            {
                clearDates();
                lblW1D1.Text = scheduledatepicker.Value.AddDays(0).ToString("dd");
                lblW1D2.Text = scheduledatepicker.Value.AddDays(1).ToString("dd");
                lblW1D3.Text = scheduledatepicker.Value.AddDays(2).ToString("dd");
                lblW1D4.Text = scheduledatepicker.Value.AddDays(3).ToString("dd");
                lblW1D5.Text = scheduledatepicker.Value.AddDays(4).ToString("dd");
                lblW1D6.Text = scheduledatepicker.Value.AddDays(5).ToString("dd");
                lblW1D7.Text = scheduledatepicker.Value.AddDays(6).ToString("dd");
                lblW2D1.Text = scheduledatepicker.Value.AddDays(7).ToString("dd");
                lblW2D2.Text = scheduledatepicker.Value.AddDays(8).ToString("dd");
                lblW2D3.Text = scheduledatepicker.Value.AddDays(9).ToString("dd");
                lblW2D4.Text = scheduledatepicker.Value.AddDays(10).ToString("dd");
                lblW2D5.Text = scheduledatepicker.Value.AddDays(11).ToString("dd");
                lblW2D6.Text = scheduledatepicker.Value.AddDays(12).ToString("dd");
                lblW2D7.Text = scheduledatepicker.Value.AddDays(13).ToString("dd");
                lblW3D1.Text = scheduledatepicker.Value.AddDays(14).ToString("dd");
                lblW3D2.Text = scheduledatepicker.Value.AddDays(15).ToString("dd");
                lblW3D3.Text = scheduledatepicker.Value.AddDays(16).ToString("dd");
                lblW3D4.Text = scheduledatepicker.Value.AddDays(17).ToString("dd");
                lblW3D5.Text = scheduledatepicker.Value.AddDays(18).ToString("dd");
                lblW3D6.Text = scheduledatepicker.Value.AddDays(19).ToString("dd");
                lblW3D7.Text = scheduledatepicker.Value.AddDays(20).ToString("dd");

Or do I have to write all +/- 42 labels worth of code for each day?

 and I do not want to have the following months dates added to the labels after they hit the end of the month for the selected month in the datetimepicker names scheduledatepicker.

 

 

Answer 1

Got it! 

 

Label[] dateLabels = { d01, d02, d03, d04, d05, d06, d07, d08, d09, d10, d11, d12, d13, d14, d15, d16, d17, d18, d19, d20, d21, d22, d23, d24, d25, d26, d27, d28, d29, d30, d31, d32, d33, d34, d35, d36, d37, d38, d39, d40, d41, d42 };

for (int i = 0; i < dateLabels.Length; i++)

{

for (int d = 1; d <= Eom.Day; d++)

{

if (d < 10)

dateLabels[d - 1].Text = "0" + d.ToString();

else

dateLabels[d - 1].Text = d.ToString();

}

}

Answer 2

Ok I have tried chaning things around a bit.  I have renamed all of the date labels to d01-d42.  I have created this for loop, but I have not been able to get them to populate.

 

See Code below for for loop.

 

        {
            var Eom = scheduledatepicker.Value.AddMonths(1).AddDays(-1);
            Label d = new Label();
            if (scheduledatepicker.Value.DayOfWeek == DayOfWeek.Sunday)
            {
                for (int l = 1; l <= Eom.Day; l++)
                {
                    for (int i = 1-1; i <= Eom.Day; i++)
                    {
                        d.Name = ("d" + l.ToString("dd"));
                        d.Text = scheduledatepicker.Value.AddDays(i++).ToString("dd");
                    }
                }
            }
}
 

Answer 3

For Windows form you can use "this" instead of page like below

Label lbl = this.Controls.Find("LabelW"+i.toString()+"D"+j.toString()) as Label;

 Here may be little bit change in code i give you a idea about how to find control in window form.

If you find any error then makes some changes in code

 

Answer 4

Find Control is part of the System.Web.UI this is not a web application this is a winforms application.

Answer 5

I think this error was occur because you are using Lables in a Table

 

So try to replace "Page" with Table name

bl = (Label)Tabel1.FindControl("LabelW" + i.ToString() + "D" + j.ToString()); 

Answer 6

if (scheduledatepicker.Value.DayOfWeek == DayOfWeek.Sunday)

{

clearDates();

Label lbl;

int add = 0;

for (int i = 1; i <= 3; i++)

{

for (int j = 1; j <= 7; j++)

{

lbl = (Label)Page.FindControl("LabelW" + i.ToString() + "D" + j.ToString());

lbl.Text = scheduledatepicker.Value.AddDays(add).ToString();

add++;

}

}

}

 

I do get the following Error:

The name 'Page' does not exist in the current context.

Hello Marcus!

 

Sorry there was little mistake in code you can try this code

 

 

if (scheduledatepicker.Value.DayOfWeek == DayOfWeek.Sunday)
            {
clearDates();
Label lbl;
int add=0;
for(int i=1;i<=3;i++)
{
for(j=1;j<=7;j++)
{
lbl=(Label)Page.FindControl("LabelW" + i.ToString() +"D"+ j.ToString());
lbl.Text=scheduledatepicker.Value.AddDays(add);
add++;
}
}

 

As per my understanding you are trying to display the date of 7 days for 3 week(according your code).

for this purpose we can use looping concept. For your code we  take two loops.

Outer loop for week and inner loop for days.

inside the inner loop we will find the Label control using  Page.FindControl

 

lbl=(Label)Page.FindControl("LabelW" + i.ToString() + "D"+j.ToString());

if value of i=1 and j=1 then  lbl represent the "LabelW1D1" so using 

value of add=0; 
lbl.Text=scheduledatepicker.Value.AddDays(add)  we assign the text to LabelW1D1
scheduledatepicker.Value.AddDays(add)=scheduledatepicker.Value.AddDays(0) for LabelW1D1

so on

when i=1 and j=2

now add=1;
scheduledatepicker.Value.AddDays(add)=scheduledatepicker.Value.AddDays(1) for LabelW1D2
when i=1 and j=3
add=2;
scheduledatepicker.Value.AddDays(add)=scheduledatepicker.Value.AddDays(2) for LabelW1D3
Please reply me if i got your question wrong or this code is not as you expect...

Answer 8

Thank you Pankaj,

 

Can you give an explanation regarding the loop?  I'm semi following you on it. 

Answer 9

Hello  Marcus you can write above using the loops. Using loop you can minimize the text code.  rewrite above code in this manner

 

if (scheduledatepicker.Value.DayOfWeek == DayOfWeek.Sunday)
            {
clearDates();
Label lbl;

for(int i=1;i<=3;i++)
{
for(j=1;j<=7;j++)
{
lbl=(Label)Page.FindControl("Label" + i.ToString() + j.ToString());
lbl.Text=scheduledatepicker.Value.AddDays(i+j-2);
}
}
