evaluate data in row and change text on asp:ButtonField accordingly.


I am building a website for my hockey league.


I have a gridview that displays the current weeks scheduled games. Ideally I have added a column to the end of the gridview that I would like display 1 of 3 values. If the game has already been played I would like to display the score of the game; if the game has yet to be played I would like the column blank and if someone on either team has indicated that they can't make the game I would like to display a button that says "subs needed" and take you to another page to sign up to be a sub. Can this be done? I have been able to change the background color of the line based on the two boolean flags from the database using the RowDataBound event handler but I can't seem to find a way to set the value of a specific field in my row. (The background is set for the whole row.)

Thanks in advance -eric

DataGrid ValidationRule or IDataErrorInfo validation code called multiple times for each data change

Following my enquiry regarding a problem in Datagrid validation, for which managing exceptions is apparently a problem, I tested the two other methods: using validation rules, or implementing the IDataErrorInfo interface. I ran into other problems there, more insidious this time. This has been done on Windows7 (32-bit), .NET 4.0.30319. 1) IDataErrorInfo When this interface is implemented, the this[string columnName] property is called four times for each modification: two times before the cell enters edit mode (with the old value in the corresponding property) two times when the new value has to be validated (with the new value) It strikes me as not really efficient, is there something wrong with my code? Here's the C# part: using System; using System.Windows; using System.Collections.ObjectModel; using System.ComponentModel; namespace DataGridTest2 { public partial class MainWindow : Window { ObservableCollection<User> users; public MainWindow() { InitializeComponent(); users = new ObservableCollection<User>() { new User { Name = "Teddy", Age = "2" }, new User { Name = "Avi", Age = "19" } }; datagrid.ItemsSource = users; datagrid.Focus(); } } public class User : INotifyPropertyChanged, IDataErrorInfo { string name; public string Name

change TD background/foreground color problem.

I have some javascript that is suppose to change the color of a table TD. the CSS file has an entry like this .tdcommand {} HTML TD is like <td colspan="2" height="162" valign="top" class="tdcommand"> if i put a background-color:red or whatever in the CSS file, the color is shown correctly. If i change it via a script it doesnt seem to have any impact. using the alert() to post info, i've found its entering my function correctly and getting the correct info. the important part of the function is thisfor (var i = 0; i < document.styleSheets[0][CSSRules].length; i++) { if (document.styleSheets[0][CSSRules][i].selectorText == obj) { document.styleSheets[0][CSSRules][i].style[prop] = color document.getElementById("opt_" + option).innerHTML = "'" + color + "'" } }   as i said, using the alert() i can validate that its finding the class ok (obj = .tdcommand) and the property is correct (background-color) and the innerHTML update is working fine. I use this same function to set other things, such as text color and highlighting of span's without any problem. what am i missing?   Justin
