I am trying to validate my cells pending on what cell they are in when the dataerror fires for my datagridview.
Here is my code:
private void dataGridView1_DataError(object sender, DataGridViewDataErrorEventArgs e)
{
if (_licDataSet.LicenseFileTable.Rows(e.RowIndex).Columns(e.ColumnIndex) == "test")
switch (dataGridView1.CurrentCell.OwningColumn.Name)
{
case "AllowAsRemoteDesktopColumn" :
// do not think there are any checks for this column
// we'll find out shortly though!
break;
case dataGridView1.CurrentCell.OwningColumn.Name :
// ^^^ this errors with "A constant value is expected"
// do something
break;
}
}
I am erroring at the ^^^ position as you can see from the message.
What am I doing wrong? I would think that the owningcolumn name was constant at this point...?
Help!
*** EDIT*** How do I get the column name of the current cell is my question if the above doesn't work? *
I ended up creating an enum of my expected value and referencing them. It was the only way I could guarantee if the changed that I'd get a compile error.
You need to provide a constant representing one of the values the CurrentCell.OwningColumn.Name could be. Something like "anothervalue", and not a property of an object.
In c# switch statement's cases can only be 'const' literals , strings and enums. It cannot be property or field of class. msdn link: http://msdn.microsoft.com/en-us/library/06tc147t(v=vs.71).aspx
You are using as a case statement the same property as in a switch check. Probably you need to replace second case with default
keyword.
