C# - Exporting Data To Excel, With Jagged Columns Due To Dynamic Data?
Jan 25, 2010
I have a bit of an interesting problem where I need to create an Excel data dump from some data in the database, but rather than it being something simple I have some complex data to merge, below is an example of the data that I have to deal with.
RecordId |QuestionName | Answer
1 |Your Name? | Bob
1 |Your Title? | The Builder
2 |Favorite Movie | The Matrix
2 |Favorite Car | Mustang
What I need in the end is the following
RecordId|Record Name |Date |Cost | | | |
1 |Test Entry | 1/1/2010 |2.0 |Your Name? | Bob | Your Title? | The Builder
2 |Test Entry2 | 1/1/2010 |20.25 |Favorite Move | The Matrix | Favorite Car | Mustang
Now I'm using SQL Server 2005 for the reporting and ASP.NET 3.5 (C#) for the application. I'm looking for the best way to do this. The number of items in "tblRandomInfo" is variable, and can have as many as 20-30 Q/A pairs per record. I cannot easily do a pivot, even a dynamic pivot due to the nature of the data.
Edit.A solution is valid either on the SQL Server or C# side. But note that information in tblRandomInfo can contain line breaks.

I am trying to export my Model to an Excel sheet. I have 31 fields out of which only 29 are exported. Among the 3 fields that I am not able to export 2 are of type Enum and one of DateTime. Their is another DateTime field also, but that is exported properly. Here are few fields of the model :
[EnumDataType(typeof(Suffix)), Display(Name = "Suffix *")] [Required(ErrorMessage = "Suffix is Required")] public Suffix NameSuffix { get; set; } [EnumDataType(typeof(InquiryStatus)), Display(Name = "Status")] [Required(ErrorMessage = "Status is Required")]
[Code] ....
Among the 4 fields above, NameSuffix, Inquiry_Status & FollowUpDate are not exported. InquiryDate is exported.

I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:
I am binding data from a dataset to a grid and exporting data from the grid to an excel.if the the number of items in the grid is greater than 50000,an error message is displayed.

I need a way to export data from MySql database (or simply from DataTable) to Excel and set colors of particular rows based on one of the fields' content.

[Code]....
But I don't know how to set colors to particular rows. Also, I don't know how to make Excel treat text fields that look like numbers as text to avoit scientific notation.
I currently have a data grid that exports to Excel on an ASP.NET page (which is used for reporting purposes) which works great until we put it under the stresses of a full scale production environment. With a multitude of users using it it seems to fill up the server memory quite quickly since the data thats being pulled is rather large. The requirements of the page are: The data needs to be queried and exported to excel, so theres no point to getting around that. I've noticed that xls files are rather large in comparison to their xlsx counter parts, using xlsx files would be fine for my application. I've noticed that xlsb (Excel binary) are even smaller(approx 25% the size of the their xls counterpart). Is there anyway to change my code to export to xlsb (first choice) or xlsx rather than xls? I think it has something to do with Mime Types but I'm not positive.
