That is, I want to dynamically generate columns in my DB, and store these values. So how do I go about achieving this.

Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";

I am looking for best practice for uploading excel data in Sql server 2000 database through asp.net web application. Excel data will be predefined Format with almost 42 columns and out of 42 10 fields are mandatory and rest are conditional mandatory. i.e. if data exists it should be in defined format. I also need to validate for special character, length, specified format and so on.After validating, i need to store valid data into sql server table and provide export to excel functionality for invalid data for exporting in same excel format with indicator to identity the invalid cells.
View 3 RepliesI have an html table with rows and cells. And I have dynamically created a label and would like to assign the label to one of the cells of the table. What I am doing is I have a JavaScript which executes a code behind method and it would not accept an already created asp.net label. So I have created the asp.net label programmatically but cant assign it to the table to display the text value of the label. Below is the code:
[System.Web.Services.WebMethod] public static void EndCandiateTest(){
try { totalTestMarks = ts.RetrieveResults();
grade = tsp.RawScoreAndGrade(totalTestMarks);
remarks = tsp.ScoreInterpretation(totalTestMarks);
testResults = "Raw Score: " + totalTestMarks.ToString() + "
Grade: " + grade + " Remarks: " + remarks;
ts.ShowResults(testResults);
} catch (Exception e) {
} }
protected void ShowResults (string results). I want to display this label in an already existing html table.
messageLabel.Text = results;
I come from MVC side, where these things make more sense (of course just because I know a bit about it) and my webforms are still sucky sucky.
I got a page where I want the user to upload a file (Excel).
Not too worried about the upload timing out, but after uploading this file will be processed (time & attendance data to be written to the database)
So what I'd like to happen is everything happen asynchronously with the page being updated as the file are being processed.
Also, I'm not sure.. won't I need excel on the server to have my code read the excel file?
