Gridview checkbox without datafield

Is there a way to display checkboxes in a checkbox column in a gridview without defining the datafield? Without a valid datafield the checkbox is not displayed.

You can add whatever controls you'd like to the datagrid by handling the proper events, like ItemCreated, and inserting them into the row.

I've added a checkbox column to the gridview but at run time there are no checkboxes shown because the datafield property is empty. I do not want to use that property for the checkbox column but I want the checkboxes to display.

I must be missing something. The data field is empty but you still want to bind the column? Is the datagrid set to auto create the columns?
The data column should not be empty, a checkbox is boolean (discounting tri-state checkboxes), so set the data column values to false.

Why do you want only GridView. Gridview will be rendered only when DataField contains something. So I dont like this.

Why dont you use Repeater to render your html?? U can place any control you want and even if it has DBNull, you can change the style of rendering the control easily. Confused | :confused:

Problem with reading excel before moving data to sql server

rajg8215-Jul-09 6:59

I'm reading excel file data using sql bulk copy and uploading the same inside sql server database:

My current code is:

public bool ImportMethod()
{
string sqlConnectionString = "Data Source=192.1.1.10;Initial Catalog=GePReleaseStatus;user=sa;password=sa;Integrated Security=True";
//Create Connection to Excel WorkBook
using (OleDbConnection connection = new OleDbConnection(excelConnectionString))
{
connection.Open();
OleDbCommand command = new OleDbCommand("SELECT SrNo AS SrNo,Module AS vcrModule,DefectNoClientName AS intDefectNo, FeratureID AS intFeratureID,Priority AS vcrPriority,Description AS vcrDescription FROM [eContract_4.0.13$]", connection);
using (System.Data.Common.DbDataReader dr = command.ExecuteReader())
{
// Bulk Copy to SQL Server
using (System.Data.SqlClient.SqlBulkCopy bulkCopy = new System.Data.SqlClient.SqlBulkCopy(sqlConnectionString))
{
bulkCopy.DestinationTableName = "ExcelData";
bulkCopy.WriteToServer(dr);
return true;
}
}
connection.Close();
}
}

Now the problem is:-
1) I'm unable to read the excel, as it has formatted cells at top ?
(common error: IErrorInfo.GetDescription failed with E_FAIL(0x80004005).)
2) how to read the excel from any particular row ?
3) Is it possible to read multiple sheets from a single excel file, how ?

Thanks

raj

1. If there is simple formatting, you can read it clearly. Otherwise you need InteropServices or other to read anything from anywhere.
2 Indeed you can read from any particular row. Just use
SELECT * FROM [w1$A10:B10]"; where w1 is the sheetname of the excel workbook.
3. Hey, you are calling select statement from your worksheet. So that implies you can ready any worksheet from your workbook, just call the worksheet name properly.

Communication between classes

Hello.

I'm just beginning with ASP.NET. I'm developing an application that uses the TcpListener. I've put all network related functions on a separated .cs file, trying to have everything a bit ordered. I use BeginRead method and I need to make the Default page know that some data has arrived in order to process it.
How can I pass a message, generate an event or call a function of the Default page? What's the more proper solution?
I've been reading some tutorials about events and delegates but I'm not able to see how they can work in two separated files... Frown | :(

Thanks in advance.

You can pass parameters to any page in the URL, something like this Http://myserver/myapp/mypage&ID=123

Where ID is a parameter that will be used by your page.

You retrieve the value of ID by using the following code:

myID = Request.QueryString("ID")

Based on the value of ID, your Page_Load event of your page can make whatever actions are necessary.

Try that. Thumbs Up | :thumbsup:

Does this cause the page to reload? I need something really fast: It's for realtime video.

Re: Communication between classes

Yes. It causes the page to reload. Sounds like you have a more complicated situation.
You might want to give a more detailed explaination of what you are trying to accomplish and the folks here can point you in the right direction.
There may even be a solution aleady developed here or at CodePlex http://www.codeplex.com/[^]

The people here are very helpful.

Good luck with your project.

what I'm trying to do is to make a Windows Forms Application that grabs images from some cameras. It processes the images and stores results, keeps statistics and so forth. Then I want to develop a Web Application that communicates with the other, displaying real time images grabbed, and being able to configure different parameters like pan, tilt, zoom, processing thresholds, etc.
I'm just beginning with C# and ASP.NET and I feel a bit lost... Laugh | :laugh:

By now I'm able to transfer images from the WF application and displaying them on the ASP.NET one. But I need to use buttons. By now I'm trying to implement some sort of messaging or callback functions to display the image on the ASP.NET app each time a new grabbed image is received.

Hope this helps a bit more.

And I've seen it in these first days here, people is pretty much helpful... Thumbs Up | :thumbsup:

Web page update

Ah ...
Hmm. Sounds like you want to have the web page automatically update based on an event (like a new image).

This is a bit out of my realm. I could only offer the idea that you create a javascript timer that calls out to grab any new data that might be available. This is not the most elegant way to do things, but it would work. Wink | ;-)

Clearly, the more advanced guys here could offer you a better solution.

Re: Communication between classes

Abhishek Sur15-Jul-09 10:56

Yes.. Just make an AJAX request for latest updates continuously using SetInterval of Javascript. Let after every 30 seconds your page sends a server request to an HTTP handler placed in the server. This handler will give you appropriate response when new images are refreshed or return nothing...

By this way you can update your client site properly with latest updates.

But mind that, making too much calls to the server means lots of server bandwidth might be considered.

So if you want to avoid extra server calls, I would recommend to use Silverlight which can hold TCP channel from the client.
Thus it is easier to handle this in case of silverlight.

If you want only HTML, then there is no other way than to call XMLHttpRequest 's continuously. ...
