View 6 RepliesI have a Customer database table with a text field named customerPicture with the name of the JPG file.
I have made a Customer Entity class with the LinQ to SQL Designer.
I also have a FormView displaying Customer instance binding with a LinqDataSource.
My problem is:
I want to make some modifications when some control want to bind the customerPicture field.
For example, when my FromView want to show the field customerPicture I want to return not only the JPG file name, I want to modify this string to add the complete file path and perhaps resample the image to a determinate width and height.
I know that is posible to defeine a partial class named Customer to implement certains partial methods, like OnCustomerPictureChanged(), but I dont know how to do this.
If I make, in this Customer partial class, a new method, for example getResamplePicturePath(), how could I invoke it from a FormView?

View 13 RepliesI am trying to access an item default.aspx.vb which is in the class page in the app_code folder. Why am I unable to access this through intellisense?
If
Not m_qKnown.Contains(HRefs(i))
Then
here is the class page. In my vs, m_qknown is underlined in blue. How come I can't access this queue in this code behind page for the default.aspx? In my intellisense, if I try to prefix it with the name of the page (Charlotte.vb) Charlotte.Webcrawler. after this dot there is no m_qKnown. There are some queuing event handlers and that's about it.
I'm trying to avoid adding more items to a queue if the item is already in the known queue. I'm happy to email this website application to anyone who would like to test it.

I've been attempting to walk through the "Creating a Data Access Layer" tutorial found [URL] I create the DB connection, create the typed dataset and table adapter, specify the sql, etc. When I add the code to the presentation layer (in this case a page called AllProducts.aspx) I am unable to find the NorthwindTableAdapters.ProductsTableAdapter class. I tried to import the NorthwindTableAdapters namespace, but it is not showing up. Looking in the solution explorer Class View confirms that there is a Northwind class, but not the namespace I'm l ooking for. I've tried several online tutorials that all have essentially the same steps, and I'm getting the same results.

I am trying to develop logic to add dynamic controls to page via class method. So I want to know how can we access the ASP.Net Page object reference in class method.
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 base class called BasePage, and a master page called SiteMaster. All my content pages inherit BasePage using BasePage instead of System.Web.UI.Page. Now, I need to access some functions in BasePage from my master page SiteMaster, let's say, the function is called "DisplayClientName()". How can I do it? Searched the Web, have found tons of similar questions but not solid solutions.

View 8 RepliesI'm trying to use a MasterType TypeName to access a class with master pages. This works when I'm using .NET 2.0, VS 2005, and C#. When I try this using .NET 3.5, VS 2008 and C# I get the error:
The type or namespace name 'classA' could not be found (are you missing a using directive or an assembly reference?) and it is pointing to the Default.aspx.designer.cs
In the default.aspx I have:
<%@ Page Language="C#" MasterPageFile="...
<%@ MasterType TypeName="classA" %>
I have added a folder App_Code to my project and in that folder I have a class file "classA.cs" that contains:
Using ...
Namespace Project.App_Code
{
public class classA : System.Web.UI.MasterPage
...
The main difference that I see from where it works and where it doesn't work is that where it doesn't work it uses the namespace called Project.So I figure my problem is in the including the class classA in the namespace or properly including the namespace and / or App_Code directory in the MasterType TypeName which I don't seem to be able to figure out.
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.

I have a div on my master page and I want to use it for showing page errors. I have an error display class and it works fine. My problem is that in some instances, the error gets displayed even before the tag resulting in (non)-display of the message. This is mostly with code that has response.redirect.
I want to counter this by having the error shown on a div within my master page.
How can I access <div id="errorSegment" runat="server">?
