View 1 Repliesi have a hidden textbox in my aspx page. The aspx page also has a masterpage in the <% @Page> directive.
<input type="hidden" runat="server" name="txtType" id="txtType" />
actually in aspx.cs i am getting txtType.ClientID="ctl00_MainHeaderContent_txtType"
I have a webpart in a webpart zone in this aspx page. In the webpart CreateChildcontrols() I need to access this hiddenTextbox value. I am able to access it as
string TxtValue = this.Page.Request.Form["ctl00_MainHeaderContent_txtType"];
But instead of hardcoding I want to access as a control in the page or form. How can I do that I want to do as looping through the controls in the page but Page.Controls.Count gives 1 and that is MasterPage. How can I get the entire controls in the page and loop through and find the hidden textbox. I also tried as string TxtValue = this.Page.Request.Form["<%=txtType.ClientID%>"] in CreateChildControls() of the webp[art. But could not access hidden textbox like this.
I have a class UserControlBase that inherits System.Web.UI.UserControl and my user controls inherit UserControlBase class. UserControlBase has some common functions that are used in all user controls.
I want to put error display funtion to UserControlBase as well so that I may not have to declare and manage it in all user controls. Error will be displayed in some label in usercontrol. Issue is how to access label which is in usercontrol in UserControlBase in function ?
Currently, I have many controls and objects such as Chart1 of mschart as part of the public partial class _Default : System.Web.UI.Page.
At the bottom, I've created a second class that is not part of the _Default webform class. How can I access the webform controls from this second class?
For example, I want to do
Chart1.Series["Series1"].Points.AddXY((pointIndex + 1) * 40, datapoints[pointIndex]);
I want to pass pointIndex integer and the datapoints array.
I know that Chart1 was created protected global access modifier in the designer.cs but when I changed it to public, it still had a problem.
Since we can access the private data member of base class in the derived class with the help of friend function. How can we do the same in C# asp.net? I mean whats the alternative of friend function in C# asp.net
View 2 RepliesI have a class (name PageBase) that is inhariting System .Web.UI .Page and all my .aspx page behind classes are inhariting this class. This way I have put some common things in PageBase class.
For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.
Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .
I dont want to pass control as argument to function in parent class, is ther any other way ?
Suppose we declare and define the variable in one class let say FirstClass and we want to use that variable in another class let say SecondClass which is outside of FirstClass .how to do this?
View 2 RepliesI am to access a method on my master page. I have an error label which I want to update based on error messages I get from my site.
public string ErrorText
{
get { return this.infoLabel.Text; }
set { this.infoLabel.Text = value; }
}
How can I access this from my user control or classes that I set up?
I have this Control directive in a usercontrol (i've changed the namespace and class name):
<%@ Control Language="C#" AutoEventWireup="true" Inherits="Namespace.Path.To.ClassName" %>
<asp:TextBox runat="server" ID="txtComment" TextMode="MultiLine" ValidationGroup="comment" />
ClassName is a class that lives in a class library and this is the class:
namespace Namespace.Path.To
{
public class ClassName : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.TextBox txtComment;
protected void Page_Load(object sender, EventArgs e)
{
HttpContext.Current.Response.Write(txtComment == null);
HttpContext.Current.Response.End();
}
I have build a UserControl with separate code behind file.In that code behind file i have defined some public properties in the Partial class of user control that was automatically generated.Those properties will initialize some properties of controls that are used in the control.Now, in .aspx page i used this User Control and initialized the public properties through code behind of aspx page for dynamic contents.

View 2 RepliesI am adapting a book example of a shopping cart application, and have almost, got it complety working. I am using an access database rather than a sql server one used in the example. Earlier on I found I had an issue with the sql datasource where I had to specify the provider name as below of I would get the error about provider keyname not being supported
ConnectionString
="<%$ ConnectionStrings:OICConnectString %>"
ProviderName
="System.Data.OleDb"
Now, within once of the classes, it refers to the database connection string and this is now where the same error occurs, when the page requires this class and it must be because the provider name is not specified, but i'm new to C# so I'm not sure how to do it.
Here is this part of the class
public
static
bool WriteOrder(Order o)
{
string cs =
WebConfigurationManager
[code]...
I am trying to do something such as:
<%= Class1.GetName %>
in my ASPX page, but my class1.vb can't work like this, I have to declare it first in the aspx page, how can I make my Class1.vb file be shared among the whole website?
During an adaption of a book based example application, to use an access database instead of sql server - I have come up with the final issue: It will not insert into the database! I suspect it might be to do with the OrderID, I do have it set to autonumber,but I am not too sure. This is the class that does the inserts, by adding customer information to customer table, order information to order table and ordeitems information to the orderitems table. When submitting this information on the webpage, there is the custom error that an error has occurred in your order due to this code page code behind
bool success = OrderDB.WriteOrder(order);
Session["cart"] = null;
Session["order"] = null;
if (success)

View 5 RepliesI have two projects in one solution :
Class Library for my BLL and DAL classes Web Application for my PL
Now I just use the keyword "using" in the BLL and DAL classes and get access to their methods easily. but now I try to reference the BLL and DAL in the web application project through the "using" keyword but it won't let me (the name space couldn't be found (are you missing reference ?)) .. then I tried to reference the library's dll (grabbed it from the ClassLibrary/bin/debug) and the same error just popped out again!
