Between date in C#

To validate the 7-day date range in C#, you can use the DateTime class and some simple logic. Here's an example of how you can achieve this:

// Get the values from the textboxes
DateTime fromDate = DateTime.ParseExact(txtFromDate.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture);
DateTime toDate = DateTime.ParseExact(txtToDate.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture);

// Calculate the difference in days
TimeSpan difference = toDate - fromDate;

// Check if the date range is within 7 days
if (difference.Days == 7)
{
    // Date range is valid
    // Perform your desired actions here
}
else
{
    // Date range is not valid
    // Display an error message or take appropriate action
}

To automatically adjust the "FROM DATE" when the "TO DATE" changes, you can use an event handler for the "TO DATE" textbox's TextChanged event. Here's an example:

private void txtToDate_TextChanged(object sender, EventArgs e)
{
    // Get the new "TO DATE" value
    DateTime toDate = DateTime.ParseExact(txtToDate.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture);

    // Calculate the new "FROM DATE" value
    DateTime fromDate = toDate.AddDays(-7);

    // Update the "FROM DATE" textbox
    txtFromDate.Text = fromDate.ToString("dd/MM/yyyy");
}

By using these code snippets, you can ensure that the user can only enter a 7-day date range in both textboxes and automatically adjust the "FROM DATE" when the "TO DATE" changes.

To restrict users to a 7-day date range, use JavaScript. On TO DATE change, set FROM DATE to 7 days earlier, and vice versa. Example:

From Date:

Hey Sushant, try the below sample code.

ASPX Page:

    
    


    

        FROM DATE:
        
        

        TO DATE:
        
    
    

Page_Load event:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        DateTime currentDate = DateTime.Now.Date;
        fromDate.Text = currentDate.ToString("yyyy-MM-dd");
        toDate.Text = currentDate.AddDays(7).ToString("yyyy-MM-dd");
        fromDate.Attributes["min"] = currentDate.ToString("yyyy-MM-dd");
        toDate.Attributes["min"] = currentDate.ToString("yyyy-MM-dd");
        toDate.Attributes["max"] = currentDate.AddDays(7).ToString("yyyy-MM-dd");
    }
}

Hello Sushant,

try the below sample code to get difference between two dates in C#

ASPX Page code:

    From Date:  
    

    From Date:  
    

    Difference:  
    

    
    
    
    
    

C# Code

protected void Difference(object sender, EventArgs e)
{
    DateTime FDFromDate = DateTime.ParseExact(Request.Form["txtFDFromDate"], "dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture);
    DateTime FDToDate = DateTime.ParseExact(Request.Form["txtFDToDate"], "dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture);
    txtDifference.Text = (FDFromDate - FDToDate).TotalDays.ToString();

    // you can write custom validation for date selection limit here.
}

Thanks
