You can create a datatable entirely in code, add the columns to it, and populate it, then just use it as if you had loaded it from a database.
Are you using C# or VB? I'll post a sample when I know which language you like.

Hi,
This is called Pivoting of Data.
Please have a look over my article: Pivoting DataTable Simplified[^]
This can get you a flexible and customized result with a clean code.

Good Evening My friends
I have been helping you , now its your turn to help 
Due to Limitations in the Telerik, meaning that there is no nice Pop Control , and i want to create my own as i did in my previous article. I have used the DevExpress Popup Control and i have a Telerik Gridview inside it and i can nicely search for records and i can select the record from the Grid and i have a button that saves take an ID of that record like
protected void btnselect_Click(object sender, EventArgs e)
{
String Ref =null;
foreach (GridDataItem dataItem in grdactsandbills.MasterTableView.Items)
{
CheckBox chkselect = (CheckBox)dataItem.FindControl("chkselect");
if (chkselect.Checked)
{
Label lblReferenceNumberID = (Label)dataItem.FindControl("lblID");
Ref = lblReferenceNumberID.Text;
}
}
txtreferencenumber.Text = Ref;
}
this Button is in a PopupModal(DevExpress) , when this button is Clicked if assign that value to a textbox that is not part of the modal. and you can see i am doing it on the server side and the break point goes there and the watch shows that yes the value has been assigned to the textbox, but after i close the pop, the Textbox is empty. I am just buffled by this. Below is my markup
<asp:UpdatePanel ID="Update1" runat="server">

Hi,
I have a seacrh which returns me a list of objectA.
Can I bind this list to gridview for display or which is the best way to do this .
Thanks
|
|
|
|

Yes, you can bind List to gridView for display.
This [^] looks as Bes and easiest way to do same.
You simply need to do:
GridView1.DataSource = myList
GrdiView1.DataBind();
myList can be ArrayList or any other list.

Hi,
Click here[^] and here[^]
The above approach will do the job for you but in my openion you must consider the following:
1. It will work on in Internet Explorer. No other browser will be able to run this.
2. There might be some functionality which will not work because of security issue.

From your schema file (*.xsd), you create classes with the xsd tool (I describe that in my article Bernie’s Trackviewer[^]). Then instantiate the objects from those classes, and finally write ("serialize") them to xml files.

I understand how to use App_Offline.htm, and most of its caveats, but what I can't seem to find information on is how it deals with executing threads. What I'm concerned about specifically is this. Our company website allows our users to post online payments for their bill with us. Lets say we go to do production maintenance at night, and drop in App_Offline.htm. But we have 3 users submitting payments at that exact moment. I know that App_Offline.htm will block any further responses from coming from ASP.NET, but does it abort the web services calls, or does it allow them to finish, and only then tear down the sessions?
Thanks in advance.
|
|
|
|
|
If the file exists, then ASP.NET shuts down the application and sends the contents of the file back to the user's browser for any new requests to dynamic pages in the application.So in your case the server side code for payment process wont execute, because users are basically locked out of the application.
You can get more resources in
http://www.15seconds.com/issue/061207.htm[^]
Hope this will help.

Thanks for the reply, Shahriar. But I was referring more to what happens to any active Web Service calls being made. Let me try to explain it a different way. Let's say the payment process takes 30 seconds to return from a 3rd party vendor (they own the Web Service, we're just calling in to it). 10 seconds in to a call, we drop in App_Offline.htm, and shut the site down. Does the payment process Web Service call to our 3rd party vendor complete? Or is it aborted by the shutdown of our application. Either way, I know that the user is still going to see a "Site Offline" message.
Thanks again!

Hi,

Hi,
I have a list of doc files located on a server, I need to open them on a client side in asp .net form.
I don't want the users to be able to enter the directories or the files (security permissions) directly,
\\servername\c$\directory name, so I removed all security permissions, but I still want the users to be able to open
the files from the web site, can you help me?
thanks,
Yefi

You can receive the filename by a querystring.
string filename = Request.QueryString["filename"];
Then you can validate everything you need and, if the file is a simple textfile, you can open it and write all its contents to the page.
You can even do this with other file formats, but then you must set the document type and maybe need to use a page only to "download" the file.
|
|
|
|
|
Not good for me, if the filename permissions on the server are minimum I can't open the file.
|
|
|
|
|
But not even the code running at the server side is able to open the file?
If that's the case, it will be impossible to solve.
I think what you want is something like this:
Direct connections to a folder or http folder: They are not able to access the files.
Connections to a page - Such page will be able to see only files located at "some directory". If "some directory" is protected from reading, you may need some type of impersonation.
But, then, the flow will be:
Clients (without any access) will access your page at the server.
Such page will have some type of impersonation, can verify if the file only contains the names (no .., no drive letter and so on) and, even then, it only has access to one directory. It reads the file (if valid) and then returns its contents.
If you need, I can detail better about impersonation, but I don't think that you will really need that.
|
|
|
|
|
First you need to give the user some way of selecting which file they need to open. This can be done through may ways, may be you list all the files on you page?
Once a user selects (knows) which file they want, they don't permission on the server side. But asp.net will definitely need a permission to read/access the files from that folder. If asp.net does not have permission then it will fail.
|
|
|
|
|
In order to open the document on the client side, the encoding must be set to an appropriate type for the relevant document. The thing you need to set is known as the MIME type, for instance - if you want to open up an Excel document, the content type should be set to application/vnd.ms-excel. I hope that this helps.
