View 1 Repliesi have a user web control wich has the website menu. this menu is viewed through out the entire web site.
i would like to mark the selected link, on the menu with in the web user control,in some way (red background or w/e) the thing is, i cannot manage this from client side since there is a page_load on every click on the menu (witch brings up a different page). the only thing i can think of is saving the click to the session and then retrieve what was clicked and change the style accordingly via c# in the code behind.
I want to use a couple of instances of the same control on a page. The user control is intended to display a list of records in a repeater. The aim is that the second control will show a list excluding the IDs in the first control The control has a number of public properties, including IDsInThisList, and IDstoExclude. The query will exclude the IDs in the second property.
What I would like to do is get the record IDs from the first instance of the control (IDsInThisList), and pass them to the second contro as the IDsToExclude.
I have a test page where I am setting the properties of the controls in code. As you might guess, it's not working! The first control displays the top 3 items, as desired, but the second display the records 1-7, rather than records 4-10 because it is not receiving the IDstoExclude from the first control When I response write the IDstoExclude from the first control in my testpage, the string is empty. (if I do it from within the control, it shows the IDs)
How can I get the controls to fire in order and pass values to each other?

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.
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.

View 12 RepliesI have a ASP.Net project that is setup in such a way that it can be dropped into any site and "just work." All the paths are relative to the current file, not relative to the "~". The paths are determined by ThePath = this.TemplateSourceDirectory;
This is working for everything expect registering a custom control that is created and added to one of the pages. I can add the control just fine with the Page.LoadControl but I cant cast it as the correct type to access anything.
How can I add a reference to the class from within the code itself?
I am part of a team that is developing a SharePoint web part. My task is to create a user control which will ultimately be wrapped in another class for presentation in a web part. Because of these requirements, I must fit all of my code in a single user control.To organize my code in the code-behind, I created a few private classes for the different objects which are represented in the database. I want to add some exception handling whereby if some sort of DB exception is thrown I can update a message on the page informing the user of the problem.
My problem is that the page-level controls are inaccessible from the private class where I'm issuing the query, so even if I catch the exception I have no way of directly accessing a Label control to populate the error. I tried to create a baseclass with an EventHandler defined, but when I throw events from the private class I'm not able to catch them for whatever reason. I'm far from an OOP expert Here is a snippet:

i have an ASP.NET website which is using a filestream to read in a PDF image from a UNC share on a remote server 2003 box.
i attempt to load the file on the site (which simply embeds a PDF viewer on the site) but when i debug the code, it's throwing a security exception when i attempt to access the file. saying "access to ___ path is denied".
so... i granted access to the UNC path directory to the ASPNET user. i also granted access to the user that's specified for anonymous access in the site itself in IIS.
nothing.
however, i grant "everybody" access and the file comes through.
so, i need to know WHO is trying to access the file. the assumption is either the ASPNET user or the anonymous user setup in IIS. neither of which is gaining access. i tried to set up file auditing on the server2003 box but it's not logging a failure in the security event log when i get an access denied exception.

I have a user control (uc1) which inherits from uc2. uc2 has a user control (uc3) declared in the markup. I am trying to access uc3 from uc1 but I get NullReferenceException. I thought due to inheritance uc3 would instantiate but looks like I am missing a step.
Clarification:
How does the child user control inherit the markup from the base class? The server controls in the base user control are null in the code behind of the base user control. Why?
I'm trying to create a user control class that extends Panel. Essentially, what I want to do is to have a panel that fires off an event whenever it's clicked upon.
So, I create something like this:
[Code]....
And then, in the ClickPanel.ascx.cs file:
[Code]....
I'm not exactly sure whether this would work as I haven't had the opportunity to test it yet.
The problem is that I can't have a class inherit from Panel. Creating a user control class requires that my class extend User Control - at least that's what the error messages have been saying up until now. The problem is that if I do extend it from the base class of UserControl then I lose all the functionality of the Panel itself and the entire thing is rendered pointless.
