i have a Page_Load function but i cant acces them in the Page_Load function...
using System; using System.Collections.Generic; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls;
namespace NorthwindCascading { public partial class _IndexBasic : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { CarService service = new CarService(); List<string> Makes = service.GetCarMakes(); ddlMake.DataSource = Makes; ddlMake.DataBind(); ddlMake.Items.Insert(0, " -- Select Make -- "); } } } }
I have added the code-behind file manually so i guess i am missing something... it just says that the ddlMake element is not defined in current context.
I have a stored procedure that builds a table. I need to delete the table before running it or I get an object already exists error. How do you code Drop Table in C# code behind. I have am calling the SP with execute non-query statement.
Inside my boxLang_OnSelectedIndexChanged() event I got this :- if (txtbox1.Text != "" && txtbox2.Text != "") { ScriptManager.RegisterStartupScript(Page, Page.GetType(), "confirm", "confirm('Changing the language will clear the text in the textboxes. Click OK to proceed.');", true); txtbox1.Text = ""; txtbox2.Text = ""; }
Now what is happening is that. When I select a different item from the drop down list this confirm box does show up BUT it first clears the content of the text boxes and then this confirm box appears. What I want is that the textboxes content should be cleared ONLY when OK is clicked.
I tried putting a html replace code into a string which is then placed into a drop down menu. Only problem is it still appears as ² instead of a small 2.
Is there a way to change the code inserted when you drag and drop a control on a form?For instance, the application I'm working on always has Display=Dynamic and CssClass="errormessage" in a field validator. Is there a way to get VS 2008 to use these defaults, and insert the code for them when I drag and drop a control onto the page?

I am new to Ajax in general but I have a series of cascading drop down lists that are working fine. I'm using them on a form that I want to be able to either add a new row of data to the database or edit an existing one. I have the insert a new row working but editing an existing one is a bit trickier. The drop down lists are only part of the form but I would like to be able to query for a row id and set their values. Right now I'm querying for a row of data and populating the form with its values on page load and all of the fields work except for the drop down lists. I assume that this is because when the page is loading the web methods haven't run yet to populate the cascading drop downs. Therefore I can't set the selected value because there aren't any values yet. So therefore I'm pretty sure I need to do this from a web method so that it runs after the lists are populated or while the lists are populating but I don't know how.

I have a Telerik:RadTextBox control in my markup called txtName. I'm trying to retrieve the inputed value in the code behind with foo = txtName.Text; but var and txtName always show an empty string.
I guess the code couldn't be easier. Basically what's happening is, when I click my 'save' button, there's a postback and the text in the RadTextBox just disappears.
update Found the problem. My web.config file had a different version of the Telerik dll file that was actually in my bin folder.

I'm trying to set session variables in one page, and retrieve them in my code file in the page that it posts to.
I keep getting this error. I put the correct namespaces in, and enabledSessionState = true to my application files, but no luck.
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.
I'm just calling a session variable, and I get that error
e.g,
Public AUID As Integer = Convert.ToInt16(Session("AUID"))
