Datagrid and Datatable In Pocket PC Vb.net2005

I am working on a pocket pc application by using vb.net 2005.

I have 2 questions about the datagrid and datatable.

1. What I want is that when the datagrid is populated then application should check the datagrid first cell value and if it is null then it should change the backcolor of that row to Red.

2. I am creating a datatable on form load event and the adding rows by executing the sql statement by using datareader. Now I want to add a tablestyle to that datagrid and want to set the width of the datagrid columns.

Simple is that how I can set a datagrid table style while setting the datasource to datatable?

Thanks In advance

You should be asking this in the Mobile Development forum since the .NET CF Framework is a smaller subset of the full .NET Framework. It doesn't matter which language you're using, the limitations of the CF Framework change how the code is written.

Retrieving data in parts

Dayekh11-Apr-10 3:43

Hi all,

I'm trying to allow the user to store an article in a table where the article body can take ANY number of parts each displayed as a separate page on a webpage.

I thought I would store the entire article in the Article table but separated by a delimiter like, the only problem is, after I store the record, how would I go ahead a retrieve the data IN PARTS so that it can be displayed in a repeater?

Hi,

I would not do that. I suggest you store the smallest part you're interested in as one item, then build larger stuff from multiple items. This is similar to storing first name and last name separately, it gives easy access to both of them, and when you need both together, you can easily combine them.

So create two tables:
table "article" holds overall information on an article (ID, title, author, date, ...);
table "page" holds the content of one page, the page number, and the article ID.

Hi Luc,

Thanks for the reply. Let me just make things clear.

1 - I will store the small details in the Article table.
2 - I will store the parts of the articles as separate records in a "Parts" table.
3 - Each part will have an article ID.
4 - I will call details FROM article table AND parts table WHERE ID is the one clicked on by the user

One last problem: Due to the user being able to store ANY number of parts PER article, how do I connect each part to a repeater? I would like the repeater to do "Paging" on each part. Is that possible?

Yes, store each part/page of an article with its part/page number and with the one article ID so it points into the right row of your articles table.

I don't know about the Repeater Control, I've never used any, I haven't done any ASP.NET
However I trust it can be done, in fact I expect it to be pretty simple.

Thanks for the reply. I will research Custom Paging. I'm sure the answer lies there.

Cheers!

I wouldn't store the entire article commna delimited. What if there's a comma in the article?

I'd store the parts in some kind of Parts table, then have another table that tells which parts go with which article.

You are going to need a web service, so there is your starting point.

No, it's not. The web server isn't going to have any permissions on the client machine to look at anything. Your client component is what's going to have to do the searching on the client machine. It just has to be told what to search for. That, the server can provide.
