Comment on Datagridview: Get SelectedIndex of DataGridViewComboBoxColumn by sachin kalse

sachin kalse — Thu, 19 Nov 2009 08:47:32 +0000

Hi,
Thanks for the “life saving” work around.
I am using it further to enable a button which is outside of grid depending
on the value selected in ComboBoxCell.
The code below works well if I change the values of only one ComboBox, but
when I try to change values in multiple it fails.
e.g. to disable the Save button I have to make all ComboBox values = “Select”
which is default value, even after that IsItemSelected method returns “true”

After inserting a break point at
>> if (cell.Value.ToString() != “Select”)
I still get the last value in Cell which is other than “Select”

void comboBox_SelectedIndexChanged(object sender, EventArgs e)
{
int selectedIndex = ((ComboBox)sender).SelectedIndex;
//MessageBox.Show(“Selected Index = ” + selectedIndex);
if (selectedIndex > 0)
{
btnSave.Enabled = true;
}
else
{
// check for all rows
btnSave.Enabled = (IsItemSelected() == true ? true : false);
}
}

private bool IsItemSelected()
{
bool isItemSelected = false;
foreach (DataGridViewRow dgvRows in dgvPending.Rows)
{
DataGridViewComboBoxCell cell = (DataGridViewComboBoxCell)dgvRows.Cells[0];
if (cell != null)
{
if (cell.Value.ToString() != “Select”)
{
isItemSelected = true;
break;
}
}
}
return isItemSelected;
}

Please guide
Thanks in advance

Comment on Removing items in a list while iterating through it by MaxCulpa

Yep, Josh is right.

All solutions that manually grind though the list with for or while loops are “procedurally oriented”. You should just use the RemoveAll method provided in the List class.

Example:

playerShots is a list of Shot objects for a game. Location is a Point that is a property of a Shot. The following code removes all shots from the playerShots list that have reached the top of the screen…

playerShots.RemoveAll(delegate(Shot s)
{
return s.Location.Y < 0;
});

Let C# work for you.

Holy cow, it’s is just appalling to see so many solutions that reek of disregard to runtime efficiency! Josh has posted a clean and solution. All solutions that include copying, converting to arrays etc are almost as bad as the sort of solutions that PHP and BASIC coders come up with.

When there are methods already present in the .NET library, *use them*. Just like Josh does. That’s what they’re there for.

The reverse iteration is just what I needed. I would’ve never thought of trying that. Thanks!

Comment on C#: List of struct by Stephen

Stephen — Fri, 30 Oct 2009 21:28:27 +0000

MyStruct s = myList[index];
s.MyField = “Foo”;
myList[index] = s;

I realize this discussion is quite old early on, but I would really like to know why the code above works. If the list indexer is just a function that returns a copy of the struct, how can you do myList[index] = s? Aren’t you just assigning s to a temporary copy? Isn’t myList[index] on the left-hand side of the assignment operator just returning a temporary copy of the struct at that index? Or is myList[index] purely a reference when it’s to the left of =?
