AFAIK, there is no way to get the value on server which is changed by JS for a label. Label is rendered as HTML span and the values of HTML elements like this are not posted to server. If you know CSS, you can make a text box look like a label and change the text box value.
Please ignore my previous reply.

Use <asp:hiddenControl to change its value.
Anything other than input types are reflects its changes through javacript in server (Not even Serverside ReadOnly/Disabled TextBoxes). So even if you change the innerHTML of the control, you will not find it in server side. Rather use
document.getElementById("hiddeninput").value = "SOmeText";
document.getElementById("LabelID").innerHTML = "SomeText";
I hope this will help you. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Thanks Friends .. thanks a lot for you support
I implemented a textbox but since that textbox need not be Editable Can i change its style to that of a LABEL

Of course budd.
Just add a Textbox. In the server side add:
txtbox.Attributes.Add("readonly", "readonly");
This will make the textbox readonly and also reflect any data being changed in the client.
If you make
txtbox.Readonly = true / txtbox.Enabled = false;
the textbox value changed in the client will not reflect in the server.
Hope you understand.

Hello,
I am looking for a web survey tool/framework (commercial or freeware, doesn't matter, but .NET for integration purposes) that allows to build web forms. Does anyone know one ?
Best wishes,
Desmond

Since I didn’t implement any third part web survey tool, I can’t suggest you a good one. But a quick search on google(Link) fetched dozens of links including commercial and free version. You please go through the links and choose one.

You can try the Survey™ Project at http://www.surveyproject.info . Survey is a free and open source web based survey and form engine toolkit for Microsoft's .net. written in asp.net and C#. It should match your needs.

return
true

}
function
AjaxValidatorResult(returnValue,context)

else
context.isvalid = false
;
ValidatorUpdateDisplay(context);
}
function

You please check the ClientID of that control on the master page. It may be different on master page and content pages.

Suppose i have a registration form, at the registration time, a vouchar has een generated and that has a PIn number(ID). And it has 5 days validity.

You can't.

Turns out that it's not urgent for anyone except you.

The best way to do this, is a windows service, because it can always run, check the DB, and send the emails.

This smells of 'I have taken a paid job and have no clue how to do it'. You're on your own, do some research, I've told you what to look up.

Some people go crazy to point their urgency... 
|
|
|
|
|
To clarify more...
When the Registration form is submitted, put an entry to the database with current time. Use your windows service to check if Currenttime.AddDays(5) == now.. and send mail here.
Hope this would make your job easier.

Hi!
I have an application that has a Windows Application Project, a Data Access Layer Project and a Web Application project.
I am using a DataSet with Classes in my Data Access Layer. Here is how my method looks in the Data Access Layer:
public void SaveTimesheet(dsWBGT dsTimesheets)
{
WBGT.DAL.dsWBGTTableAdapters.TableAdapterManager saveTimesheet = new WBGT.DAL.dsWBGTTableAdapters.TableAdapterManager();
saveTimesheet.TimesheetTableAdapter = new WBGT.DAL.dsWBGTTableAdapters.TimesheetTableAdapter();
saveTimesheet.BackupDataSetBeforeUpdate = true;
saveTimesheet.UpdateAll(dsTimesheets);
}
When I access information from the Windows application everything works fine and I am able to save. When I try to do the same for my web application it gives no errors but the information does not get saved to the db.
I have created a form on my aspx page and when I hit save the following code executes:
protected void btnSave_Click(object sender, EventArgs e)
{
WBGT.DAL.Class_Managers.clsTimesheet_Manager timesheetDataManager = new WBGT.DAL.Class_Managers.clsTimesheet_Manager();
JobId = (int.Parse(ddlJobId.SelectedValue.ToString()));
Date = cDate.SelectedDate;
StartTime = (int.Parse(ddlTimeStarted.SelectedValue.ToString()));
EndTime = (int.Parse(ddlTimeFinished.SelectedValue.ToString()));
CalculateGrossTotal(StartTime, EndTime);
txtGrossTotals.Text = GrossTotal.ToString();
timesheetDataManager.SaveTimesheet(dsMain);
lblTimesheetStatus.Text = "Done!";
}
Can someone please tell me how to get the information from the form into the database?

|

timesheetDataManager.SaveTimesheet(dsMain);
Where is dsMain defined and populated? Have you stepped through this code with a debugger? That should help you to determine what is happening.

I have created a new instance in the code behind for the aspx page. I know that the DataSet implimentation is wrong because I do not see the values inside the dataset at debugging time.
My question is how can I access the dataset in the DAL?
I created a new instance as follows:
WBGT.DAL.dsWBGT = new dsWBGT();

You're asking us how to use a library for which you presumably have the source code, and we do not. If it doesn't return what you need, change it so it does.

What Error are you getting ?
Vuyiswa Maseko,
Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

Hi,
Can anyone tell me how to display multiple records of data as one row in a Gridview. I have data coming from the database in the following format, but I would like to display records in the same group as one row when bound in a Gridview. Any help would be greatly appreciated.
Thanks
PRODUCT GROUP JAN FEB MAR
Product A Group1 20 30 10
Product B Group1 40 100 20
Product C Group1 80 45 70
Product A Group2 50 30 40
Product B Group2 20 10 100
Product C Group2 90 30 60

If you want to group stuff together like this, you probably need to nest gridviews, or perhaps repeaters, to give you more control. Your data source should then change accordingly, so each nested control is bound to a group.

Thanks for your response Chris,
If it is no bother, could you please post a sample code snippet? put in mind though that I can't change the datasource because it is being used in multiple places but I was thinking that the grouping could be done on databound..
|

If you can't change the data source, then you have a lot of work ahead of you. I was imaging two controls like this:
<asp:Repeater >
<ItemTemplate>
<asp:Repeater>
Then you bind a list of the top level ids to the repeater, and in onitemdatabound, look up the inner repeater and bind it to the table that corresponds to the id passed into the row. Obviously you add code to style it the way you want, define the columns, etc, the point is just that you get the granularity to create and style the data into groups.
I imagine if you're not allowed to create a new method to return a group of tables, that you'd need to write code that binds to the group names, and then searches the data source to filter based on group name.

I have a website (web-project), which I can publish locally and then run thru the virtual directory.
But when I moved that published code to the hosting of www.godaddy.com, it doesn't work and says:
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
Why it happens? No one error happens on my side, the pages are simple, moreover, the one I tried to run has the only one control with static text, under masterpage. Even when I set the cutomErrors="Off", nothing is shown for me and no additional information...
Please advise.

Well, what's obvious is, there is an error, and you've not succeeded in setting up your web.config in such a way that the error is reported to you.
That it's reading the web.config means that you have .NET installed ( although perhaps the wrong version ). Beyond that, you need to find out the actual error, in order to fix it.
