Web Forms :: Easy: Checking A Value Then Marking Checkbox

Feb 22, 2010

This seems like it should be easy..... I am pulling some results from a database and then comparing them to a checkboxlist ... if a checkbox item within a list of checkboxes is within this result list, then I want to check that box...this is an 'easy' version of what I am trying to do...

Web Forms :: Checking All Checkboxes On The Page Using 1 Checkbox With Or Without Javascript

Nov 1, 2010

I have found plenty of examples where the checkboxes to be checked are within a datalist, gridview or other datacontrol like that.. but i dont have that setup..

I have individual checkboxes within my page and need to provide a way to check or uncheck them all..

I cant use a checkboxlist because of the layout of the page.. so not sure if it would be easiest with javascript or do it with the checked event for the single check box that will be used..

I know that may not be the best or cleanest way, but is there a better way?

Reason i cant use a checkboxlist for the larger set of checkboxes, is that a few of them will have additional fields that need to be completed if they chose certain checkboxes.. so i have those controls next to the checkbox that they belong with..

The Un-checking Of The Checkbox Does Not Seem To Be In Sync With The 'hidden' Value?

Feb 24, 2010

When I used the html Helper Checkbox, it produces 2 form elements. I understand why this is, and I have no problem with it except:The un-checking of the checkbox does not seem to be in sync with the 'hidden' value.What I mean is that when I have a bunch of checkboxes being generated in a loop:

<%=Html.CheckBox("model.MarketCategories[" & i & "].Value", category.Value)%>

and the user deselects and checkbox and the category.Value is FALSE, the code being generated is:

<input checked="checked" id="model_MarketCategories_0__Value" name="model.MarketCategories[0].Value" type="checkbox" value="true" />
<input name="model.MarketCategories[0].Value" type="hidden" value="false" />

This is wrong since the Value is False the checkbox should NOT be checked.

Web Forms :: Marking Specific Pages With A Flag?

Nov 1, 2010

I have a website that has many pages. Half of the pages need to redirect a user to a specific page. The other half DO NOT need to redirect a user. How can I mark a page as needing / not needing redirection without going into each Page_Load and manually writing my code. I was thinking about creating a MasterPage and creating a virtual property called NeedsRedirection and overriding it in the webpages, but I soon realized that the webpages still do not INHERIT from the master page. Any other suggestions as how to mark a page as needing redirection? Can I do this in the markup to make it easy?

Configuration :: Marking Files As Synchronized?

Nov 6, 2010

The Copy Web Site tool shows both the local and remote versions of most of my files as "New" But I know they are the same because I recently copied them. I would like to do something to mark them as "Unchanged" without recopying them and thereby changing the creation timestamps. Are any of the following possible?:

A tool that compares files and marks identical files as synchronized. Explicitly telling VWDE to mark files as synchronized. Going around the user interface to mark files as synchronized. How does VWDE keep track of which files are synchronized?(In case you are interested, the way things got in this state was that I copied the files with the remote site as local and the local site as remote. I did it that way because I had been editing files directly to the remote site.)

Configuration :: Deploying An ActiveX Control And Marking It As Safe?

Apr 7, 2010

I have a dll written in VS 2008 that needs to act like an ActiveX control called via JavaScript from a HTML page and writes a file to the users local machine.

The main code is like the following:


The control works if I turn off a lot of security in IE and manually run regasm on the users machine, but how do I automate the process and let it run without the users having to lower their security levels?

Do I need to get the dll signed? If so how do I get it signed and how do I deploy and install it to users?

Vb.net - Include Dynamic Code Which Was Easy In Classic ASP

Jun 8, 2010

I've got an ASP.net file, and I'm trying to include dynamic code which was easy in classic ASP.

Here is what I have tried so far:

<%@ Register TagPrefix="TagPre" TagName="header" Src="alg/classes.aspx"%>


<!--#include file="alg/classes.aspx"-->

But neither of these seem to work. The content of classes.aspx is:

<script runat="server">
' Square class
Public Class square
Public sqRows As Integer 'Numbers of rows this square has
Public sqCols As Integer 'Number of columns this square has
Public sqArray(,) As Integer 'The square array
' Initialise square array to match size of canvas
Public Sub initSqArray(ByVal canvCols, ByVal canvRows)
ReDim sqArray(canvCols, canvRows)
sqRows = canvRows
sqCols = canvCols
End Sub
End Class

Finding Easy Way To Generate Random Distinct Colors?

Anybody know of any easy way to generate random distinct colors (preferably the same random each time). I am trying to create a MS Chart stack graph, and each series is based off of a service order type, but that list can grow, so I'm creating my series in a loop based off a distinct query and want to assign a color to them dynamically at run time. It would be nice though if they didn't change every run.

Using ADO.NET - To Modify The Table To Make It More Easy To Select Data From It

Apr 27, 2010

I'm trying to use ADO .NET to select data from this table in excel. I'm not sure at this point if I need to modify the table to make it more easy to select data from it. Here's what the excel table looks like

I guess I don't know where to really start. I'm pretty much trying to grab the numbers in the middle(design pressure) based on Mull length in inches and opening width. so the user will input the height and width of window. then if it's going into concrete or wood.. if it;s wood then in the clip to opening row if he uses (2)A or 3(b) he will have a DEsign pressure of 170 if mull length is 42 and opening width is 70. in the same 70 column if he uses (3)a 0r 3(b) his DP will be also 170 in this case.. So I will have a user interface and ask the user for a width of window and height of window which will be the Mull Length and what substrate(wood or concrete) based on that I want to display if u use this amount of screws A or B u will get this DP.

Architecture :: Design For Easy Integration Into Customers Websites?

Aug 22, 2010

The project, once done, will provide a "portal" into a limited portion of the client's database. All clients are using a SQL database, but various server software products are involved (MSSQL, MySQL, and others).

My question, however, has more to do with the "look and feel" of the finished product. We want to be able to integrate our 'portal' easily into the client's websites and have it look as seamless as possible. Obviously, placements of logos, etc. -- but also colors, fonts, etc.

Client sites tend to be simplistic in design. We envision the customer placing a link to our site from theirs, and our site will be running on IIS on their server. At least that's the plan.

The goal right now would be to make as much of this "parameter driven" as possible, so that a lot of the install can be accomplished through some simple settings, isolated in one or two files such that at installation time we can tweak those settings and be up-and-running in a short period of time with a site that integrates reasonably well with the customer's.

But I'm uncertain as to whether there is a better approach. Obviously, we could try to redesign our site with each install with the basic design of the customer's, but this would be cost-prohibitive in some situations. So, I'm thinking about a "second best" alternative that may be adequate in most circumstances.

C# - Efficient / Easy Method To Validate For Empty Text Boxes?

Oct 1, 2010

I have a about 6 or 7 text boxes which needs to be validated to make sure they are not empty from server side code. So how I usually do this is, check each textbox 1 by 1 to ensure that they are not empty. Are there any other efficient methods to do this? I have searched on SO and have found out that adding all the textboxes to a list and using a for each is a much better method. Are there any other ways that this can be achieved? Thanx a lot in advance :)
