Assigning a CssClass to a control works just like you'd expect. Except for when it doesn't. I find myself frequently doing view source on pages so I can figure out how MS is rendering stuff so that I can then debug the CSS problems. I've looked in vain for coherent MS documentation that would tell me on a per control basis what stylesheet elements they'll actually respond to.
I would think it would be a Good Thing to use CssClass rather than control properties, but I grow weary of the guessing game with some controls (try managing the width of a horizontal Menu control without getting your menu items spaced three light years across).
Am I missing something terribly obvious in this architecture? Is there some Holy Grail (or at least Holy Hand Grenade) that I'm overlooking that would explain, in very simple words and as if to a small child, just exactly what CSS these controls are willing to play nice with?

Is it possible to resize or hide the SQLDatasource control in design time
They make tables and other control look bigger than what they will look at run time
Thanks for your answer

Hello All,
Got a funny little thing happening when I am trying to pass 2 bits of information from one page to the other. I am using public properties on the source page and trying to retrive the properties on the target page. What is happening is that I can only retrieve one of the elements but not the other. Both are setup in the same manner but I just can't seem to get one of the values. Below are the snippets of code. Any assistance will be greatly appreciated. Oh, I can only retrive the integer value. I cannot retrieve the UserName.
SOURCE PAGE SNIPPET:
public partial class Main : System.Web.UI.Page
{
private int pUID;
private string pUserName;
public string userName
{
get
{
return pUserName;
}
}
public int uID
{
get
{
return pUID;
}
}
TARGET PAGE SNIPPET:
if (PreviousPage != null)
{
if (PreviousPage.IsCrossPagePostBack == true)
{
//this.Label1.Text = (string)Page.PreviousPage.FindControl("username").ToString();
if (PreviousPage.userName != null)
{
pageUserName = PreviousPage.userName.ToString();
this.Label1.Text = String.Format("{0} is the user name.", pageUserName);
}
else
{
this.Label1.Text = "It's empty.";
}
if (PreviousPage.uID.ToString() != null)
{
pageUID = PreviousPage.uID.ToString();
this.Label1.Text = this.Label1.Text + String.Format(" {0} is the user name.", pageUID);
}
}

I can only assume that pUserName isn't being set properly. Are you sure the value of this variable has been set before you access the Property?

Calling ToString() on an int will never return a null value, so this check is redundant. Make your property get/set a nullable int instead.

I thought of the variable not being set so on the Source page I added:
this.lblSuccess.Text = String.Format("Successful login. Welcome back {0}", userName);
which displays correctly. I set the value on the postback after I retrive the name from the dB. So therein lies my problem.
Flow:
- Display initial page with login txtBoxes user clicks continue.
- Post back to same page and do the db stuff and assign values.
- User clicks another continue button to go to the next page.
- Target page finds the public variables with IntelliSense so it knows it's there.
Crazy man. Crazy.

Is it possible to start a function or subroutine AFTER an aspx page has loaded? I have tried Page_Load(), read into AJAX and tried a few things (UpdatePanel and ScriptManager), and tried calling a vb function from javascript on the page (calling back to my _Default class); thus far, nothing has worked.
My goal is to develop an application that checks for the existence of registry values and logs a line of text to a listbox control after each registry check. This is pointless if the logging is all populated to the listbox before the page completely loads (which is what happens if I use Page_Load()). I also want this entire process to be automated so that the user does not have to click a button or do anything to initiate the registry checking.
Is what I'm trying to accomplish possible with ASP.NET with or without AJAX? Am I on the right track? Any suggestions?
Thank you!

Hi..
I have made a page using which files can be uploaded.File gets uploaded after creating a folder with same name of the particular file,within a root folder.
Now,I want that a specific group of users will be able to download not all but some files,other files will be not be accessible to them.Again another group of users will be able to download another set of files.
I hope my need is clear
So,how can this be achieved?Any suggestion,code snippet,tips will be helpful..
Thank you

You are making it difficult by creating folders for each file, not to mention creating quite a mess on the file system. If you had folders that represented the different user roles, you could have the files uploaded there and use the web.config file to restrict access to the folders based on the roles.

Thank you for response..
Actually the scenario is that, in a learning institute different courses are offered.Courses have their unique ids.And students are enrolled to one or more courses.Students will be able to download only those contents to which they are enrolled to.
So,what may be the most optimized solution to this?
Thank you in advance

Hi,
idont speek english well sorry!
I work with visual web developer 2005 asp.net for the 1st time and sqlserver2005 to achieve an intranet site for the service school.
Now what they are doing is that university is:
For each semester, the registration service write the names and num-registration ds register students this semester in an Excel worksheet for each level.
each teacher introduced the notes of his field for different students in a column (note_matière1 for example) of this spreadsheet excel.
they use Excel to calculate ways,..
I spent a lot of time to test a gridview but there is no possibility of inserting a column if I:
Num_inscription name marks_frensh
1077 ssss 12
1078 AAA 15
1079 kkkkk 16
To insert the notes they need me whenever select and then click update for each student and it is not practical !!!!!
I spent a lot of time with and excel without result.
I consulted a lot of forum was told than in the controls Infragistics, there is a grid like excel but I need the license !!!!!!!
I dont know if I happened to explain this project or not.
Thank you very much,
Thanks again.

What is your question?
Do you want a licence for the Infragistics product? Then you'll have to purchase one, just like everyone else.
If you don't want to purchase a 3rd party product, you can develop an editable grid in ASP.NET using the GridView control. An explanation of how to do this is beyond the scope of a forum question, but there are plenty of examples online. For instance, try here[^].

Why not ?

Yes, you do. So, if you can't pay for it, then you need instead to think about how their control does what you want, and write your own code to do the same.

Hi,
If I want that after only checking a certain check box a button will be activated. As for example, suppose after checking the "terms and Conditions" check box ,the "Submit" button will be enabled.
How can I do that?I am using ASP.NET(c#).
Thanks in advance.
|

|
|
|
You can do it with javascript. You need to hook OnClick event to the checkbox, get the button's object using getElementById() and use controlObject.Disabled = false;
|
|
|
|
|
or use c# and set the checkbox to postback and then put a statement like
if checkbox.checked == true
{
btbutton.visible = true
}
put that in the c#
|
|
|
|
|
Why go through a postback to show a button? The previous response using JavaScrip was perfectly adequate and would be a much better user experience.

I just thought that it would be easier to stick to one coding language
plus javascript can be turned off at the client end therefore rendering the bit of code useless
cheers for the input though!

Hi,
The C# code you are talking about,that I have to put in CheckedChanged event?
Thank you for the responses..

In my ASP.NET 2.0 application, I have to automatically intimate
users regarding their memberships via EMAILS.
I am restricted not to use any Event driven code because these emails are to be sent on regular basis.
can i use any web service to schedule the emails to be sent?
How can I search such a web service?
|
|
|
|
|
You can use windows service. Write a service and install it on server. This service should send mails at the required time.
|
|
|
|
|
Thanks for posting a reply, but I can not use a windows service (my web server does not support that)
Any other suggestions?
