Hi,
I have to write a page which receive a QueryString named LanguageID. In its Load event, after getting this parameter, I must remove it from the Request object. The reason is when the page is shown, and the user press F5 KEY (for example), the page will be refreshed without the QueryString LanguageID (This parameter is used only one time). I can image the scenario is like following:
Sub Load()
If not Request.QueryString("LanguageID") is Nothing then
strLanguageID=Request.QueryString("LanguageID")
Request.QueryString.Remove("LanguageID")'This line didn't work, the error is that the collection is read-only
Else
strLanguageID=GetLanguageIDFromDatabase()
End If
'Do other works
End Sub
How can I solve this problem? Any one can help me? Thanks.

Hi
Redirect to the same page after checking for querystring value. For example:
if (!IsPostBack)
{
if (Request.QueryString["test"] != null)
{
Response.Redirect("child.aspx");
}
if (Request.QueryString["test"] == null)
{
Response.Write("Query string is null");
}
}
Or, maintain in a session variable before redirecting to a child page. You can kill the session in the child.aspx.

Is there any reason why this code that worked in ASP.net 2.0 wouldnt work in ASP.NET 1.0 ?
(or am I going nuts ?...)
I am trying to set a value on an ascx usercontrol from its parent page
ascx code:
// this allows the page to set the name of the last CSR to work the customer
private string LastCSRName = "";
public string LastCSRNameMethod
{
get
{
return LastCSRName;
}
set
{
LastCSRName = value;
}
}
aspx code:
ReportsHeaderUrgent1.LastCSRNameMethod = Convert.ToString(DataBinder.Eval(SecondReturnedDataset, "Tables[rows].DefaultView.[0].CSRName"));

What error you are getting ?
|
|
|
|
|
Yes that would help huh 
The error I get for the line in the aspx code is:
The type or namespace name 'ReportsHeaderUrgent1' could not be found (are you missing a using directive or an assembly reference?)

Since the asp.net by default runs under the aspnet user you need to give the machine user read and write access to where ever the xml file is. You also must give the IIS_WPG group read and write access.
I have recently written an article on dynamic web.config stuff, but it is for VS 2005. Here is the link anyway:
http://www.codeproject.com/useritems/SingleWebConfigFile.asp[^]
Hope that helps.

Hi all,
I am new to ASP.NET 2.0, The application is a Project management tool in ASP.NET 2.0 using VB.NET.... im learning the language for my thesis and and i would be glad of some help.
am using SQL server 2005 express edition database
I have 2 text boxes to fill called Project name & Project Manager.
I also have 2 text boxes for date started and due completion date.
A drop down list called "size".
A series of radio buttons grouped together.....choose one.
A check box for approval.
I also have 2 required field validators beside Project name & Project manager. They are displayed through a valiation summary at the bottom of the web page.
In my database i will have the following fields.
Project Name
Project Manager
Project Size
Date Started
Due Completion Date
Approval Yes/NO

Not sure what the question is here.
I would suggest better names for your columns:
ProjectName
ProjectManager
ProjectSize
DateStarted
DateDue
DateCompleted
Approval
You will also want an identity column to help with the table I would suggest ProjectId since I would guess the table should be called Project.
CREATE TABLE [dbo].[Project]
([ProjectID] [int] Identity (1,1) NOT NULL,
ProjectName varchar(255) not null,
ProjectManager varchar(255) not null,
ProjectSize varchar(255) not null,
DateStarted DateTime not null,
DateDue DateTime null,
DateCompleted DateTime null,
Approval Char(1) not null
)
Anyway, I don't know if that was what you were looking for or not.

Thanks for your reply Ben, as regards the table that what i was looking for.
What i want to know is the code for adding a record for the table when i click on my button "add prject" for example. The code that will fill all the fields in the table in conjunction with the text boxes and drop downs etc that i mentioned in my first post.

Greetings...
I'm interested in exporting a dataset or a datagrid to excel. The hard part is formatting excel so that certain fields are colored or setting each row to have an alternating color (much like that of the datagrid itself). Can anyone assist me in better understanding how to format the excel file, mostly for color in ASP.Net for VB before it is sent to the client to download?
If anyone has some insigh I would greatly appreciate it!!!!!
Thanks, 
Shinkentb

x="Tablename"
Using C#
sqlcommand="Select field1,field2 from " + x + " order by field1";
Make sure that you put space after from and before order by clause.

I would NOT code it that way. Create a different stored procedures (or one with a tableName as a paramter). Use a switch statement to chose your stored procedure.
Dynamic SQL should only be done if absolutely necessary.
First of all, performance will be better if it stored procedures.
Secondly, stored procedures prevent SQL Injection.
Third, maintenance will be easier, especially if you change a table.
Fourth, if someone else sees your code, they won't think you are a complete beginner.

Why do you have separate tables with the same type of data in them in the first place? Why isn't the data in a single table?

Dear all,
I have an asp.net page which include asp table, i want to make it possible to drag and drop this table's columns
how should i do that???
Thanks

Maybe you can find a third party control with this functionality. Doing it yourself will be extremely difficult. You would need some serious javascript skills to write that. Even if you could write the javascript to "move" the columns you would need some AJAX to maintain the state, otherwise after a postback the grid would go back to its original state.

My Code does't work:
var myDate = document.getElementById("Calendar1").getAttribute("SelectedDate");
|
|
|
|

I don't think this is possible with the ASP.NET calendar control. You might be able to do it with the AjaxControlToolkit calendar extender.
