Jan 25, 2011
I have on my page.aspx CheckBox with IDs representing the month.
Code:
<asp:CheckBox ID="January" runat="server" Text="Janvier" />
<asp:CheckBox ID="Febuary" runat="server" Text="Fevrier" />
<asp:CheckBox ID="March" runat="server" Text="Mars" />

How do I get the value of the errorMode property set in the <system.webServer><httpErrors> element in web.config?
I'm trying to implement some "self-diagnostics" in an ASP.NET web application. When the app starts, it runs through some of the settings in web.config and confirm they're set correctly. While this code works quite nicely when the errormode is set in the <system.web><customErrors> element,
var errSec = (CustomErrorsSection)HttpContext.Current.GetSection("system.web/customErrors");
Response.Write(errSec.Mode.ToString());
it won't work once the site is deployed on IIS7 and this setting is now found in system.webServer -> httpErrors.
This won't work:
var errSec = (CustomErrorsSection)HttpContext.Current.GetSection("system.webServer/httpErrors");
And casting to a CustomErrorsSection also seems like a bad idea, there must be a better type to use?
I found this article on IIS.NET, HTTP Errors , but I hope to do this without the dependency on the Microsoft.Web.Administration library.
Okay, based on the suggestion below, I tried this:
var errSec = (ConfigurationSection)HttpContext.Current.GetSection("system.webServer/httpErrors");
Response.Write(errSec.SectionInformation.GetRawXml().ToString());
But that doesn't work either, the errSec object is null. And on a side-note, if I load the <system.web><customErrors> section using the same approach, the GetRawXml() method call fails with a "This operation does not apply at runtime." exception message.
I know how to load the whole web.config as an xml file and query that to get to the element I need. But it just seems to me like there must be a more elegant approach. How to read web.config as xml:
var conf = XDocument.Load(System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath + "web.config");
var errMode = conf.Root.Element("system.webServer").Element("httpErrors").Attribute("errorMode").Value;
but that's just nasty! And if the errorMode setting is set in machine.config or similar, it won't work.

I have a web form with about 20 fields all validated, rather than use the validation summary control.
I would like a one line alert at the foot of the form that says something along the lines of "errors were found check the fields highlighted with a *" rather than an explanation for each field that has failed validation.
Seem simple enough in theory but i cant work it out.
Is there a line of VB.net code i could use to determine if validation has failed on one or more of my validators and maybe show a label with the "errors were found please check the fields highlighted with a *" message?

I have a page where you can search and display other data, very simple layout. 1 Gridview and 1 objectdatasource. But i have 4 possible buttons that can populate the gridview..
i would like to control my objectdatasource from the code behind based on the button you click.
here is what i have right now.. but if possible, can this source not be hardcoded like this and only built in the code behind?
[Code]....
I found this site with a solution to this persons issue, but i cant seem to get mine working this way.
http://stackoverflow.com/questions/2404264/overwriting-controlparameters-of-datasources-in-code-behind
I have this as the code behind right now when you press the button.. what other parameter settings am i missing and is this the right order to populate them for the source to acknowledge my values?

I have the following issue. I am displaying a lot of models from the database. Next to each model name there is a checkbox. So a customer can check as many check box as he wants and when they click on the save button, it gets saved to a table in the database.
I have written the whole code in the code behind. (.cs). But I am having dificulty capturing the check box checked and how can I do it? Here is my partial code:
strLoadCategory +=
"<td>" + dvModels[modct]["Model_Name"].tostring() + "</td><td valign='top' align='left'>"
+ "<input type='checkbox' value='" + dvModels[modct]["product_id"].ToString()
+ "' id='" + dvModels[modct]["product_id"].ToString()
+ "' name='SaveCheck'></td></tr>";
THe number of models is dynamic based on a portal name user selects from a drop down list before this.

I have a gridview , and I made a template column with a checkbox inside.
Then , obviously , I want to check the value of checkboxes .
I'm trying to set rows' visible property to false when that row's checkbox is unselected.
I'm always getting null , no matter what I do .
So , it must be a problem with the FindControl() , but I think it is perfectly normal .

One button field called Submit and one gridview.
