Why did you make UpdateMode="Conditional" ? .
Did you call UpdatePanel1.Update() from any where of you code ?
If you change the UpdateMode from Always to Conditional, you need to call Update() method Explicitly for Update that Panel. And I think this is the reason .
Try to Make it "Always" Or if you don't need it to postback always, Just call UpdatePanel1.Update() while Paging and Sorting from Codebehind. That will resolve your problem.

Simple way is to use template field and a Hyperlink field inside that template field.

Hi...
I have developed a site through ASP.NET using VB. Whenever i go to the site, I am only able to visit the static pages. As soon as I try to visit any page linked to registration completion or the login completion, I am getting the following error:
"Server error in / Application"
Please reply as soon as possible for the solution to the given issue...
Thanks n Regards,
Gaurav

Could you please tell the details of the error.
One possible reason may be that you are not able to connect to Database. Please check connection string and database connection.

Hi Anurag.... thanx for the response... The complete error code that is visible to me is as follows:
"Server Error in / Application"
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".

Hi Friends,

to grid. pls let me know how to make the connection, can you send the code for that.
Regards,
Arpita

First of all, if you want to show your Excel data in a datagridview on an aspx page, you have to upload that spreadsheet onto the server. Best way - use the FileUpload control.
I'm only going to show you one way of doing what you want to do. If you don't like it, at least you'll have some reference on how to approach it.
To "make the connection" with an excel spreadsheet, you need to add reference to Interop.Excel.dll, Interop.Microsoft.Office.Core.dll and Interop.VBIDE.dll in your project first.
Then, in your code:
using System.Data.OleDb;
private void ExcelToGrid()
{
DataTable dt = new DataTable("sheet");
OleDbConnection conn = new OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0;data source=" + MapPath("Yourfilename.xls";extended properties=Excel 8.0");
OleDbDataAdapter SheetAdapter = new OleDbDataAdapter("select * from [$Sheet1]", conn);
SheetAdapter.Fill(dt);
DataGridView1.DataSource = dt;
DataGridView1.DataBind();
}
That should really do the trick. Obviously, you need to change $Sheet1 to whatever your sheet is called in the spreadsheet. And read up on versions of the Jet engine - i can't guarantee it's gonna work with all the living versions of Excel.

I was doing it by defining the Table Name to the Range of cells required to read/write. On Writing to excel it will automaticallly insert new row to that table.
That way, it will not depend on the sheet and structure will become more similar to other database. Because from database, you are retrieveing data from table and not from sheet.
That's my personal view.

Far as I'm concerned, he wanted to read data from an excel spreadsheet and put it into a datagridview.
There was nothing in the email indicating he also wanted to WRITE in the excel document. Nothing about any databases either.
The JET engine treats a spreadsheet like a table, far as I'm concerned.
Plus I'm sorry, i did not quite understand the part where you say:
"On Writing to excel it will automaticallly insert new row to that table."
What table? The DataTable?

HI Greg,
Thanks for this ,but i am using visual studio 2003 and c#, can i use ur code in windows forms,i tried and it is not working as below:
OleDbConnection conn = new OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0;data source=" + MapPath("data.xls",extended properties="Excel 8.0")); -- throws syntax error
please can u help.

Yes you can use this code in Windows Forms, for the most part.
As there is no
Server.MapPath class in Windows Forms you have to find a different way of pointing to the Excel spreadsheet (as in, provide the application with the physical path to your .xls file).
This is an ASP.NET forum, that's how i gathered you were using WebForms.
So it should really be:
string PathToFile = "";
OleDbConnection conn = new OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0;data source="+PathToFile+";extended properties=Excel 8.0");
var question = (_2b || !(_2b));

Hi, we need to create a site that is going to be developed by 3 people. We are going to use visual studio 2008. Once I heard that the best way to work is to create 2 solutions 1 for the code and one for the site. is this correct? If not how should we work? I have set up a source control service to keep all our source code in sync. We are students and never worked in a team to develop a site.

Fair enough.

This just plain won't work. Unless you mean to create a separate dll for the business layer, that's commonly done, but to try to create two seperate projects with the idea that you can work apart and bring them together at the end, that's fairly untenable. There's a number of free source control programs like Subversion and CVS, which you can use to set up a machine to hold the projects and then allow everyone working on it to grab code from the common repository and work on it that way.

So I Should create one solution (Web Application)and all my friends use the subversion to keep it up to date?
|
|
|
|
|
I would read up on n-tiered development. It's a good idea to move the business logic away from the presentation tier, in a dll, but I would still use subversion to work together on the project, yes.
