string c = dropdownlist1.Text;
switch (c) {
case "abuse":
gridview.datasourceid = sqlview1;[code]...
I want to change the color of the field with service count > 2
I tried to look at ondatabound event handler but my issue is being able to look through the data and change the color conditionally.
i have a grid which has start Date column and end date column, the start date column value is selected by the user using calender control.
how can i make the default value for End date to equal the start date (end date has a calender too, so the user can also change it if he wants to).
I need to insert a declaration in the codebehind function below that will make the variable "UserId" equal to the "logged-in user". In what way do I need to change the code below (elsewhere in the project, I successfully make reference to basically the same code and make the UserId equal to logged-in user by using this handler expression inside an image control: ImageUrl ='<%# Eval("UserId","Image.aspx?UserId={0}")%>'...But in the case below, the function is not fired by this expression, but rather by CustomValidator).
Sub ValidateImage(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)
If Request.QueryString("UserId") IsNot Nothing Then
' Get the connection string from Web.config.
Using conn As New SqlConnection(ConfigurationManager.ConnectionStrings("MyDatabaseConnectionString").ToString())
' Create a command object.
Dim cmd As New SqlCommand()
' Assign the connection to the command.
cmd.Connection = conn
' Appendy the parameter to the SqlCommand and set value.
cmd.Parameters.Add("@UserId", SqlDbType.UniqueIdentifier).Value = Guid.Parse(Request.QueryString("UserId"))
' Set the command text
' SQL statement or the name of the stored procedure.
cmd.CommandText = "SELECT Avatar FROM aspnet_Membership WHERE UserId = @UserId AND Avatar IS NOT NULL"
' Set the command type
' CommandType.Text for ordinary SQL statements;
' CommandType.StoredProcedure for stored procedures.
cmd.CommandType = CommandType.Text
' Open the connection.
conn.Open()
' Convert the returned result to a bytes array.
Dim bytes As Byte() = DirectCast(cmd.ExecuteScalar(), Byte())
If bytes IsNot Nothing Then
' Set the HTTP MIME type of the output stream.
Response.ContentType = "image/jpeg"
' Write a string of Binary characters to the HTTP
' output stream.
Response.BinaryWrite(bytes)
' Send all currently buffered output to the client.
Response.End()

I have a 15 digit string to encrypt.
I have tried using .NET's various encryption functions but all my encrypted strings are at least 24, 28 or 32 in length.
I have heard of CipherMode.CTS with Padding = None that produces the same length output as the input length but I can't seem to get the same result. I have toyed with the block-size, key-size and salt size.
I don't mind adding a digit to my input string to make it 16 in length.
I am binding months to a list 0-13 items default selection is 0 months duration, and years 0-8 items and 0 years is the default selection.As I know there are always going to be 12 months in a year, I could use selectedvalue or selectedindex without any perceived problem. Is there a reason why I should not use either/or of the two properties to select a list item?
View 2 RepliesI am trying to make a simple dropdownlist.Based off what is selected as the dropdownlist, I want it to open a new webpage.
For example:
Here is the dropdownlist - If they select team1, I want it to open up webpage /team1.aspx If it's team2, team2.aspx and so on.
<form id="form1" runat="server">
I thought this would be pretty simple, and in fact it's working on another dropdownlist on the same View, so I'm hoping I missed something very small that is easy to fix. Here's my code:
[Code]....
When I step through the code, the 'Active' option's 'Selected' property is being set to true. That's expected. But when the View renders, it's not selected and a look at the page source shows that the selected property isn't set. What is the problem here, and what's the solution?
i want to make one value always selected in listbox.....so that user doesnt go without selecting any...that is one remain always selected state
