C# or VB.NET are welcome. I have an <%#Eval("FirstName")%> in the aspx page, I want to replace "FirstName" to <%#Eval(employee.FirstName)%> but "employee" object is instantiated in the codebehind like this:
Public employee As New Employee How can I call this object in the aspx page? Should I can create an "employee" in the aspx? if so, how to do that.
I also want to store it in a string to check a condition . And again set it wilth a new value if a condition is met. string s = HtmlCell.Attributes["class"] not working I have added runat="server" and added an id for it as well. But i guess HtmlCell.Attributes["class"] is cant be cast into a String. I want to access the value of 'class' attribute.
I have set a global variable in a module, which I then set the value in form1.I then wish to use this in form 2 in a Select Command for a dataadapter, it however says the variable is not declared although if I call it in a MsgBox on loading form2 it tells me the variable.
My code for the select is: Me.OleDbSelectCommand1.CommandText = "SELECT Amount, [Record Number] FROM [" & _ "Test] WHERE ([Record Number] = ?)"
When the page loads, the GridView (located in an update panel) should be loaded with my first SQL SELECT statement. On the button click, the same GridView will be loaded with new data. On startup, the GridView doesn't appear.
I have a vb.net application that I want to dynamically create a search criteria using a SQLDataSource. I was trying to dynamically generate a select statement with parameters, assign that string to the selectCommand for the SQLDataSource then selectively assign the parameters.
The issue is several fields (user id) (user name) (email addr)... that I wanted to allow the user to enter any number of these and construct the select given what they entered.
That works if I just construct the string. But I want to use parameters for some sql injection protection as that page will be viewable on the internet.
What happens is I assign the select command but the SqlDataSource does not pick up that there are now some parameters that were not there before.
as in. Dim firstName As String = tbFirstName.Text Dim userName As String = tbUserName.Text Dim userIdFlag As Boolean = False
