3 errors when converting from vb.net

Valerie Meunier

5y732.NET

I have converted an application from vb.net to C# but with three errors.

Thanks for helping me.

Valerie

1) if (e.Row.RowState == 0 | e.Row.RowState == 1)

=> Operator '==' cannot by applied to operands of type 'System.Web.UI.WebControls.DataControlRowState' and 'int'

The error occurs right of the | sign (e.Row.RowState == 0 doesn't give an error).

2) How to convert this code from vb.net to C#: check whether the inputs are actually valid dates

if Not IsDate(e.Values("begdat")) Or Not IsDate(e.Values("enddat") then

I tried this: if ( ! e.Values["begdat"] is DateTime | ! e.Values["enddat"] is DateTime )

but then error: Operator '!' cannot by applied to operands of type 'System.DateeTime

3) var naamtxt = new TextBox();

foreach (var dvr in DetailsView1.Rows)

naamtxt = (TextBox)dvr.FindControl("naamtxt");

naamtxt.Focus();

Code in the aspx page:

This gives the error: "object does not contain a definition for 'FindControl' ..."

For the problem 2 you need to use DateTime.Parse and always use || sign. See this below link for DateTime.Parse, https://forums.asp.net/t/1250332.aspx?Is+there+a+function+similar+to+IsDate+for+C+that+checks+valid+dates+ https://stackoverflow.com/questions/371987/how-to-validate-a-datetime-in-c

Thanks, problem 1) is solved.
Problem 3 too: just remove the line foreach (var dvr in DetailsView1.Rows).

I'm still struggling with Problem 2 ...
