C# - Applying Styles To A GridView Matching Certain Criteria?
Dec 26, 2010
I have a GridView control (GridView1) on a page which is reading from a database. I already have a CSS style applied to the GridView and all I want to do is change the background image applied in the style depending on if a certain cell has data in it or not.
The way I'm trying to handle this change is updating the CSS class applied to each row through C#. I have the code below doing this:
It seems as if the top piece of code is always returning the string with a value greater than 0, but when I check the database the fields are all null (except for my test record of "Smith").
I'm probably doing something very simple that's wrong here, but I can't see what. Like I said, I'm still very new to this. One thing I have tried is changing the argument in the if statement to things like: if (s != null), if (s != "") and if (s == string.empty) all with no luck.
So, most of the MVC examples I find are C#, so I seem to have trouble finding samples ....(bear with me, I'm a newbie) with that said, if anyone can point me in the right direction,
I simply want to be able to apply htmlattributes / styles to my select box
I know placing all your styles in a CSS file is the best thing to do as it is a lot neater.
But does it REALLY matter if the styles are inline or in a CSS?
Edit below
My plan is to just place the styles in my MasterPage and all other pages will use the MasterPage....I believe the correct term is not "INLINE" but Embedded?
I am creating a form that has several fields at the top such as date range, area, etc, the user can change and click a submit button to view all the rows that match in a gridview below these fields. I need to know how to change the "Where" condition based on the user input on the datasource bound to the gridview.
I have gridview that I am filling with records from SQL database. However, I want to populate the gridview with records that match text search criteria. In other words, I want to be able to key in a word like "network" in a text box, pick up the text, read records and pick up on the records that match that criteria. I am doing fine with building the gridview but I am a bit new to this and I don't know what I do to do text search.
I have an application that populates a gridview based on criteria in a table. I have another table that holds data to be omitted. I will post the current LINQ code and also the end result SQL code that I need to figure out in LINQ. Below is my code:
Current LINQ Code: Dim TestType = (From test In db.Table _ Where test.TypeId = TypeID _ Select test.Id, test.Title)
I have a validation method which passes the control of a failed validation ( IE TextBox in the Gridview row ) to a method which adds a validationError style.This all worked fine until I decided to use declarative css styling on the properties of the columns in the page IE Control-CssClass="someClass".
WHen I click the update and do find an error, I pass the control to have the validationError class appended. but it appears the declarative setting overrides this when it gets rendered.
I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
im creating a class library, and adding all the necessary references for the source files contained in it.
Now, off the bat, there were over 300 compiler errors complaining about missing namespaces. The library will now compile after i just added all of the System.* references, however this is obviously not the best way.
I.e. if a classes needs using System.Web.Script;, there is no System.Web.Script reference, how would i find out which one of these references contained it? System.Web didnt.
I've been trying to setup the routing table for the urls on one of the website I'm moving across to the MVC framework.We are aiming to setup urls like:
www.site.com/sports/cycling - which is the topical page for cycling and listing all the cycling events
www.site.com/sports/cycling/road-race - which is details about the "road-race" cycling event.We have setup the following routes in global.asax:
routes.MapRoute(
"SportEvent", // Route name
"sports/{sport}/{sportevent}", // URL with parameters
[code]...
We have tried this and also run it through the Route Tester and only the second route table is pick matching.The first url (www.site.com/sports/cycling) is being matched correctly, but the second url (www.site.com/sports/cycling/road-race) does not match up correctly and doesn't match the sports event action.Have I missed an item that is required in the route table for this to work?Or is there changes that I need to make to the route table in global.asax to get this to match and work correctly?
I have an MSSQL 2005 database that has all of the employees from my company. There is a column in the table called tblusers called DOB for their birthdate. I need a to be able to return the user names for the user's who's birthday falls on the current date. This means that I would need on the month and date part of their DOB. I have no idea how to write that into the where clause.
