3 errors when converting from vb.net

Question

Hi

 

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:

 

<asp:TemplateField ><InsertItemTemplate>

<asp:TextBox id="naamtxt" runat="server" Text='<%# Bind("naam") %>' ></asp:TextBox>

</InsertItemTemplate></asp:TemplateField>

 

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