Forms Data Controls :: Gridview - Detect Dark Cell Background Colour And Lighten Readable Font
Dec 13, 2010
if a cell background colour is dark (not just black, could be many shades of grey) and then change the cell font to a lighter colour so as to contrast the background colour and make the text easier to read?
I have a grid view that displays some diary data that consists of a date, a diary entry and a diary entry type (eg holiday, info, meeting..)How can I change the background colour of a row depending on the diary entry type.So for example if the type is 'holiday' colour the row yellow, if its 'meeting' colour it red etc etc
I have a gridview that contains columns of electrical specification (value, resistance, etc.). The rows are populated with archival data from previous versions of th same part (rev A, rev B, etc.).
The question is: is there any way for me to review each row and set the font color to red if the value is different from the cell below, or above? This would highlight where changes were made to each individual revision of a part from the previous version.
I am trying to highlight a cell in a DetailsView if the value displayed is either "Desktop Computer" or "Laptop Computer" say red, I seem to be able to find examples for gridview but I don't seem to be able to apply this to a DetailsView.
I come across the technique on how to apply a different CSS class to make a row stand out from the others. However, the original code is for gridview whilst I am trying to get it works on a listview. The original code for the gridview is as follows and how to get it done on listview.
In my asp.net+vb web I am using the below code to highlight the row...
If e.Row.DataItem("Auth") Is System.DBNull.Value <> True AndAlso e.Row.DataItem("Auth") > e.Row.DataItem("Held") Then e.Row.BackColor = Drawing.Color.LightCoral
I want now only to give colour to the cell in the field and not the entire row ....
I have a grid with 5 rows and 5 columns, All containing templetefield(Combobox)I am trying to set the background color of my grid cell(contain combobox) depending upon which item is selected. (again, dependent on item selection, so background color is not permanent). How can i achieve this?
Please check this website: [URL]My question is that how can I make this effect: that hyper link(HOME) is on that dark blue background. How can I do it?
The dataGrid view is being populated. The Autogeneratedcolumns is set to false. How do I change the colour of a cell of a row depending on the text? i.e. Row 2, column 5 says "Failed". I would like to change the colour of that cell to be red.
I am reading a datareader, populating a datatable and then when finished populating I bind to a gridview. Right now, I am placing a literal in the cell of the rows based upon date differences....sort of a textual gant chart. What I want to be able to do is change the background color of the cell I am putting these literals in. I am including the code below where I am populating the cells with the text. Does anyone know how to make the background color change? I know that in a normal gridview on datarowbind I can change it but I don't know how to do this on a cell by cell basis within the code I have below.
the project I'm working on has become quite bigger then expected. And now I have pages containing about ten different GridViews (and it is likely to increase!!), each one with its own EditItemTemplate, ItemTemplate, FooterTemplate, style, properties, etc. And, of course, in the code-behind (C#) each Grid has its events handled. You can imagine: it is a mess, playing with visibility of each one, ImageButtons to hide them, further buttons for other actions. I decided to handle only events in the code behind, while using partial classes and additional classes for the rest of the code (SQL queries and everything else), but still, it's gettin a mess.
Well, my question is: is there a way to, how can I say, have a kind of separate files, where these objects are deployed, and from where I can reference them when running the application. Or, if it exists, a way to lighten aspx page and asp.cs pages. I know it's part of the job, so here the question is just intended to investigate whether a possibility to "distribute" the objects used in a web page exists.
I have a grid view populated with some data included bit fields and I made an export to excel function For each row i need to check the cell with the bit value to change the cell color, but the cell is always empty, even if is the field is set to False or True. foreach (GridViewRow row in gv.Rows)
I'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
I have implemented master pages using this example How to implement a status bar in an ASP.NET application?. I have a property on my SiteMaster.cs inherited MasterPage called Environment. On my MasterPage.master I have this code:
<body> <form id="frmMaster" runat="server"> <.. some content removed for brevity ...> Environment: <%= this.Environment %> </form> </body>
What I would like to do is evaluate this.Environment and if it is "LIVE" then colour the background of this.Environment text red, and if it's "TEST" colour it yellow. How would I do this?
UPDATE I've just added this code to MasterPage.master
The page loads, but the text does not get set, it's blank! Also the old text, that was populated is now blank too (I left the old code there for now). I also get a warning in Visual Studio:
'ASP.masterpage_master.Page_Load(object, System.EventArgs)' hides inherited member SiteMaster.Page_Load(object, System.EventArgs)'. Use the new keyword if hiding was intended.
UPDATE2: This is what I have in SiteMaster.cs
using System; using System.Web.UI; public class SiteMaster : MasterPage { public string StatusText { get; set; } public string StatusTime { get; set; } public string Environment { get; set; } protected virtual void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { if (Session["status"] != null) { this.StatusText = Session["status"].ToString(); this.StatusTime = Session["statusTime"].ToString(); } this.Environment = Session["environment"].ToString(); } } }
I have a griview which is bounded to a sqldatasource and changed dynamically. How do I change the background cell color based on the value? e.g., 0-0.5 green, 0.5-1 red, sth like that.
Now i am saving the country of the user in Session["Country"] variable , also i am using two labels and two textboxes , initially the labels text is ABN and other Label text is ACN , and initially the Textbox length against ABN Label is 14 and and ACN Label is also 14 , now i want that whenever the Session["Country"] changes to Pakistan , it must read the configurations of Pakistan node in xml file and set the ABN Label text to NTN and the textbox which is after it must allow 18 numeric digits only instead of 14 numeric digits , same for ACN Label change to BCN and textbox which is after it must allow 22 numeric digits only instead of 14 numeric digits
