• Re: how do i remove the time from the DateTime property

  [quote user="young345"] i tried this but i get an error saying 'Cannot implicitly convert type 'string' to 'System.DateTime' do you knwo what that means? and how i can resolve it thank you [/quote] As I stated in my previous post, you can NOT return a String for a DateTime property. You MUST either change the type of your property to a String or modify the DateTime value AFTER the property is currently called.

• Re: how do i remove the time from the DateTime property

  The Date property will only ever return a DateTime which will contain the full date/time. You must either use this property and convert to a formatted string or you could always add another readable property like this: public DateTime Date { get { return Convert.ToDateTime(txtDate.Text); } } public string ReadableDate { get { return this.Date.ToShortDateString(); } }

• Re: Object reference not set to an instance of an object

  Is your row really selected? Is the Cells[2] reference valid? I'd personally fire up the debugger and set a breakpoint within your code. Then, I'd check to see what is coming back as null. At that point, you can then decide what to do.

• Re: Grid and DropDownList question

  If you've placed the name of your ID field into the GridView.DataKeyNames property, then you can retrieve it something like this: Protected Sub gvEvalList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim ddl As DropDownList = DirectCast(sender, DropDownList) Dim gvr As GridViewRow = TryCast(ddl.NamingContainer, GridViewRow) If Not gvr Is Nothing Then Dim id As String = GridView1.DataKeys(gvr.RowIndex)("ID").ToString End If End Sub
