Can't change textbox backcolor

Question

User832731860 posted

Hello All,

I'm building an app that is a basic daytimer type of app. My problem is that I can't get the textbox(Textbox1) backcolor and text to change when I need it to. For instance, if there are events for January 12 and the user clicks on the Jan 12 link in the Calendar control, if there are any events in the SQL table for that day it should populate the appropriate times. The funny, or not so funny, thing is that I have another textbox named "TheEvent" that I can change the backcolor and text on with the code below and it works fine.

I don't know if it matters or not,

So, I'm lost and need help. THANKS in advance!

Mike

Here's the Code:  

 

    Protected Sub Calendar4_DayRender(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DayRenderEventArgs) Handles Calendar4.DayRender
        Dim CountEvents
        Dim BegTime
        Dim TimeEnd
        Dim NumRec
        Dim Duration As TimeSpan


        NumRec = 1

        'Label67.Text = "Enter Events Here For " & Calendar4.SelectedDate.ToLongDateString
        Label66.Text = Calendar4.SelectedDate.ToLongDateString
        MonthSelected.Text = "January"
        TheDay.Text = Calendar4.SelectedDate.Day

        CountEvents = GridView2.Rows.Count
        'MsgBox(CountEvents)
        If NumRec <= CountEvents Then

            While Not NumRec > CountEvents
                If CountEvents = 1 Then
                    BegTime = GridView2.Rows(0).Cells(3).Text

                    TimeEnd = GridView2.Rows(0).Cells(4).Text
                    Duration = Convert.ToDateTime(TimeEnd) - Convert.ToDateTime(BegTime)

                    If BegTime = "8:00 am" Then
                        Textbox1.BackColor = Color.Blue
                        Textbox1.Text = "Hi" 

                    End If
                Else
                    BegTime = GridView2.Rows(NumRec).Cells(3).Text
                    TimeEnd = GridView2.Rows(NumRec).Cells(4).Text
                    Duration = Convert.ToDateTime(TimeEnd) - Convert.ToDateTime(BegTime)
                End If

                NumRec = NumRec + 1
            End While

        End If
    End Sub

Three things

1. make sure you are not doing anything for the TextBox1's text or background color in the page load outside Not IsPostback

2. Put a break point in the line If BegTime = "8:00 am" Then  and see whether the code below is actually getting executed.

3. Make sure not any CSS styles are overriding the background color that you are applying to the textbox.. use Firebug to check this or run the code after removing any CssClass or Theme applied to the textbox.

Thanks Anzer, but I realized that coding error was a simple oversight on my part. I didn't have the appropriate code in the DayRender sub. I appreciate the quick response though.
