[Solved] Is there an overhead to a listview if its unused

Hi. I have a website where there a some different types of data (A, B, C...). The obvious solution is for me to have a separate page to display each type of data (Page_A, Page_B....). Each would have a listview to display a list of the corresponding data and each listview would be different to reflect the different types of data and also the different functionality required for each type/list. HOWEVER, there is some complex functionality separate to the actual listviews that would be common to all of the pages. This functionality is, in part, used to produce the actual datasource required for the listview.

So I have a choice. Multiple pages that have different lists displayed on each page but which replicate common functionality.

Or I create a single page that has the common functionality which also generates the datasource and that single page could have multiple listviews but then attach/bind the datasource to just one of the listviews. That would mean that there are some other listviews on the page that end up being unused. Would this cause an overhead?

Any views or comments would be really appreciated. The main functionality and code associated with the page(s) is the common code.

RadTextBox text value is always empty string

Details:
1 - Version 2011.2.712.40 of Telerik.Web.UI.
2 - Net 4.0 (therefore Visual Studio 2010).
3 - Development machine is Windows 7 Ultimate.
4 - Application pool is .Net 4.0 Integrated.

I have a simple login form (that uses a master page) with RadTextBoxes for username/password and a server-side button:

CONTENT.MASTER
<%@ master autoeventwireup="true" codebehind="content.master.cs" inherits="Administration.content" language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
   <head>
          <title>Administration</title>
     </head>
   <body>
          <form id="frmFormCriteria" runat="server">
       <asp:contentplaceholder id="cphContent" runat="server" />
          </form>
   </body>
</html>

LOGIN.ASPX
<%@ page autoeventwireup="true" codebehind="login.aspx.cs" inherits="Administration.login" language="C#" masterpagefile="~/content.master" title="" %>
<%@ mastertype virtualpath="~/content.master" %>
<%@ register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>
<asp:content contentplaceholderid="cphContent" runat="server">
   <telerik:radscriptmanager runat="server" />
     Username: <telerik:radtextbox emptymessage="[Please enter your username]" id="txtUsername" maxlength="255" textmode="SingleLine" width="200" runat="server" />
     Password: <asp:textbox id="txtPassword" maxlength="100" textmode="password" width="200" runat="server" />
     <asp:button id="btnSubmit" text="Login" runat="server" onclick="btnSubmit_Click" />
</asp:content>

When I click inside the username control, the empty message does not disappear.

While debugging, when I type enter the username and password then click the login button, the text value for both controls is an empty string.

If I change the RadTextBoxes to server-side TextBoxes the entered values are passed correctly.

What is even more frustrating, if I change the RadScriptManager to the asp:ScriptManager and leave the RadTextBoxes alone, EVERYTHING (including the empty message disappearing on focus) works correctly.

I must be doing something wrong, but what?!?

The web.config is also:

<?xml version="1.0"?>
<configuration>
    <system.web>
       <compilation debug="true" targetFramework="4.0" />
       <customErrors mode="Off" />
       <xhtmlConformance mode="Transitional" />
       <httpHandlers>
           <add verb="*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" validate="false" />
       </httpHandlers>
    </system.web>
   <system.web.extensions>
       <scripting>
           <webServices>
               <jsonSerialization maxJsonLength="5000000"/>
           </webServices>
       </scripting>
   </system.web.extensions>
   <system.webServer>
        <validation validateIntegratedModeConfiguration="false"/>
       <handlers>
           <add verb="*" name="Telerik.Web.UI.WebResource.axd_*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" preCondition="integratedMode"/>
       </handlers>
   </system.webServer>
</configuration>

Can't get solid color

I'm trying to set a solid color in the bar graph but it always gives me a fading color. Any ideas why? Here is my code

Dim bar As New ChartSeriesItem

bar.YValue = 1

bar.Appearance.FillStyle.MainColor = Drawing.Color.ForestGreen
mySeries.Appearance.FillStyle.FillType = Styles.FillType.Solid
mySeries.AddItem(bar)

chart.Series.Add(mySeries)

Also, do you know of any way to pick a random color? I.e. where I have drawing.color.forestgreen, I'd just like a random color so each bar is a different color.

How to prevent displaying text when select an item?

Hi all,

I am using RadCombobox which contains CheckBoxes as its items. When a checkbox item is checked, its Text will be displayed in Combobox's Text with the delimiter is ",".
It's OK. But I get problem when user clicks/selects on an item instead of checking it. Text of Combobox will be replaced by Text of selecting item.
Please tell me how can I prevent this action ?

Thanks in advance

line graph with unique x values

Hi,

I have been working with the chart control to make a line chart with x & y values from an external data source. The x values may be very unevenly spaced decimals values or negative numbers, so I need to set the items on this axis from code. Can someone give me a good example of how to do this?

I have a poorly functioning example below. Unfortunately, this example graphs both values as two lines.

protected void Page_Load(object sender, EventArgs e)

{

List<MyObject> myList = new List<MyObject>();

myList.Add(new MyObject { yValue = 3, xValue = -20 });

myList.Add(new MyObject { yValue = -1, xValue = -10 });

myList.Add(new MyObject { yValue = -5, xValue = 3 });

myList.Add(new MyObject { yValue = 1, xValue = 5 });

myList.Add(new MyObject { yValue = 8, xValue = 6.5 });

myList.Add(new MyObject { yValue = 4, xValue = 7 });

myList.Add(new MyObject { yValue = 3, xValue = 10 });

myList.Add(new MyObject { yValue = 7, xValue = 15 });

RadChart1.PlotArea.XAxis.IsZeroBased = false;

RadChart1.DataSource = myList;

RadChart1.PlotArea.XAxis.DataLabelsColumn = "xValue";

RadChart1.DataBind();

}

public class MyObject

{

public double yValue { get; set; }

public double xValue { get; set; }

}

Thank you for you help!
Dan
