what I need for this.
I tried to run it but it shows
Configuration Error like this

please help me to solve

it won't work.

in order to use asp.net 4.0 you have to have VS 2010. I don't even think VS2008 has the ability to support .Net 4.0.

you can always download the free visual web developer and that will get asp.net 4.0 support.

Hi guys just signed up on Code Project after giving on my fail google skills.

What I want:
I am interested in creating a Datagrid that will load details from database (cust driver which is configured with ODBC alredy) I don't how many rows I am going to have it all depends on the table im going to connect to.
I can't use the Wizard to establish a database Connection with the database I get an error (CAT_table doesnt exit or something like that) But I have been able to connect to the database by hard coding a connection string in the code behind file. But I am NOT able to take control of DataGrid because I am clueless.

So I need a tutorial on how to connect to a database with hardcode with the DataGRID and be able to UPDATE/DELETE my data without having to Programming methods and etc I want to take advantage of the DataGrid.

Can I please get links to Tutorials? That show how to hardcode everything, video tutorial would be awesome.

I am looking forward to your guys assistance Smile | :)

Thanks

Welcome to Code Project, it can be a very useful resource, however, it can also be a very harsh place for people who don't put forth some effort or only want code given to them. That being said I find it difficult to believe you could not find anything useful in the 5,300,000 results[^] returned from Google when searching for "asp.net datagrid". Especially since the first result is "An Extensive Examination of the DataGrid Web Control"

Hey,
Yeah there is a bunch of examples but everything i found was dealing with the Wizzard or an example i didn't understand.

[^]
But I think thats my answer right there? See I found bunch like that just no explanation.I can't find any example that are not using the Wizzard with explanations.

Right now I am trying to get a detailsview control to update one record in the database. I am using the smallest version of the code so I can make certain the update will work before I add more code. Right now in the new application, I have the first webform page entered by the user, they click the next button and they are directed to the second webform page. When the user is directed to the second webform page, the detailsview control for one record will be displayed.

I want the record to update a record when the user clicks a button not contained within the detailsview control. However the update has not occurred. I have tried lots of different options but nothing has worked so far. For example, I read lots of sources that said I should not have a 'new' statement in the select. However if I leave out the 'new' part of the select statements, I get an error.

What you do think I should do, have a update statement in the in the linq data source, use 2 different linq data sources, what do you think I should try to do to to make the code work.

The following is my code so far:
<pre>
<asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="Support.AttDataContext"
Select="new (Att_id, Prior_Cutoff_Date)"
TableName="Attestations" Where="Att_id == @Att_id"
EnableUpdate="True">
<UpdateParameters>
<asp:SessionParameter Name="Att_id" SessionField="AttID" />
</UpdateParameters>
<WhereParameters>
<asp:SessionParameter Name="Att_id" SessionField="AttID" Type="Int32" />
</WhereParameters>
</asp:LinqDataSource>

<asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" EnableModelValidation="False"
AutoGenerateRows="False" DataSourceID="LinqDataSource1" BorderStyle="Solid" HorizontalAlign="Center"
DefaultMode="Edit">
<Fields>
<asp:TemplateField HeaderText="Att ID">
<ItemTemplate>
<asp:TextBox ID="TextBoxAttid" runat="server" Text='<%# Eval("Att_id") %>'
BorderStyle="None"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>

<asp:TemplateField HeaderText="Prior Cutoff Date" SortExpression="Prior_Cutoff_Date">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("Prior_Cutoff_Date") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Prior_Cutoff_Date") %>'></asp:TextBox>
</EditItemTemplate>

</asp:TemplateField>
</Fields>
</asp:DetailsView>

protected void Button_Click(object sender, EventArgs e)
{
DetailsView1.DataBind();
}
</pre>

im very new to asp.net.
i develop a website for e-commerce..now i developing a page to display the statistic of the product that bought by costumer..
here is my database structure..
Table Product-ProductID,ProductName,Description
Table Transaction-TransactionID,User,ProductID,Quantity

-in table Transaction, i store the product that bought by user with user name and quantity.
-table product, store the information about product

-this is my data, assume Bag ProductID=1 and Pencil ProductID=2 in table transaction..
-for table transaction:
TransactionID | User | ProductID | Quantity
1             | ali  | 1         | 2
1             | abu  | 2         | 3
1             | qwe  | 1         | 5

i want make a statistic about the product that bought by users..
im using this Select query= "SELECT Product.ProductName, COUNT(Transaction.ProductID) AS ProductCount FROM Product INNER JOIN Transaction ON Product.ProductID = Transaction.ProductID GROUP BY Product.ProductName"

when using this query the result is,
ProductName | ProductCount
Bag         | 2
Pencil      | 1

i just want my result shown like i stated below..but i dont know how to do it..
ProductName | ProductCount
Bag         | 7
Pencil      | 3

please help me....

Try this query instead:

SQL

SELECT DISTINCT Product.ProductName, SUM(Transaction.Quantity) AS ProductCount
FROM Product INNER JOIN Transaction ON Product.ProductID = Transaction.ProductID
GROUP BY Product.ProductName

By using COUNT, you were counting the number of lines that corresponded in the result set, not the total.

so plz do help me in this issue

K.Gayathri

This is no different than navigating to any other page, secured or unsecured

No comment

hi
i am not able to navigate between secure pages(all kept inside a folder by name secure) as i have set in the web.config file inside the secure folder as follows:

<configuration>
<appSettings/>
<connectionStrings/>
<system.web>

<authorization >
<deny users="?"/>
</authorization>

</system.web>
</configuration>

i have set so because no one should access these pages without logging in......plzzzzzzzzzzz do help me

K.Gayathri

If the user has already logged in then they have been authenticated and have access to any of the pages. How are trying to navigate?

No comment

hi
thanks for the reply
yes if the user is logged in he should be able to access the other secure pages now but since i have given

after login successfully the user enter a secure page say by using the code

Server.Transfer("~/Secure/Dashboard.aspx");

so now if i am in dashboard.aspx i have some more secure pages in the same secure folder which is accessible once the user is logged in and is in dashboard.aspx...so how to do it
<configuration>
<appSettings/>
<connectionStrings/>
<system.web>

<authorization >
<deny users="?"/>
</authorization>

</system.web>
</configuration>

it is redirecting to the login page itself

K.Gayathri

Try reviewing this ASP.NET authentication and authorization[^]

hi friend
i am using form authentication using sqlserver as my database and not web.config

so that part i am ok as i can compare the values from the database using my own code and getting redirection to a secure page

but my problem now is that

from that secure page how to move to other pages which are secure

K.Gayathri

Not using web.config? This makes no sense at since you have shown the web.config you are using. You can't use form auth without it. Good luck.

No comment

hi friend
i am using web.config file only

but i am comparing the values from the database and i am not using credentials ok....you got it now what i say

so after i validate from the database i enter a secured page and from that secured page i am not able to navigate to another secured page.....

hope you got me now

Your problem probable exists in how you are doing your authorization. It sounds like you are not using the default log-in and membership provider in asp.net by your statement above. Show us the code that you are using to log someone into your site.

I think this has been addressed in some capacity a few times, but nothing recently, and nothing that addresses my exact needs. So here goes...

I am looking for suggestions to accomplish the following in ASP.NET.

The Nutshell:
I need to take a string value, from a text box on a web form, and provide it in a PDF file for download. The PDF file will also include a static graphic.

The Details:
My thoughts right now are that I should probably start with something other than a PDF that contains the static graphic, add the text, and then convert to PDF. I thought this would be possible using MS Word, but understand that there are issues when doing this on a Windows 2008 Server - which is my environment.

Ideally, I'd like to avoid a 3rd party library or application unless it's free or very cheap. The project is just as small as it sounds and can't afford the overhead.

I guess the best way to do this is to create the page in HTML and then convert it to PDF.
There is a free tool here http://code.google.com/p/wkhtmltopdf/[^] but I have not used it myself with C# or so!

Sojaner!

Maybe you can try this...

I am using unobtrusive validation to validate a form. It works in most of the browsers - IE7, IE8 in compatibility mode, FF and Chrome. However, in IE8 stand-alone mode, it fires the validation and message is shown. When I go to the field and retype the value there, the browser hangs after the first key press. The error message is not automatically disappearing. This happens for all forms and for all types of validation attributes - Required, Remote or Regular expression.

I am using jquery 1.6.2 and jquery validation 1.9

Could anybody please help me ?

Many thanks,
