Hi,
Can anyone tell me how the initial value displayed in Combo Box is
determined when a form is opened?
I am loading the dropdown from one field ("CategoryName") of a table, with
"ORDER BY ". The values in the dropdown are loaded in the
correct order, but the initial value is not the first row of the dropdown as
I expected.
The field "CategoryName" is not the primary key for the table -- the PK is

Hi,
Easy question. It seems to me that I'm following the examples correctly,
but apparently I'm not. I'm trying to retrieve the data from a row called
"row" and a column called "File". This is what I have: (xFile is the int
value in column File and tCat is the table)
First I try:
xFile = int.Parse((tCat.Rows).ToString());
Another example I found:

Is that possible? In other words, I want a dropdown list (and other list-type controls) which appears in edit more of a templated column to be populated with data at the run time. An attempt to do so results in non-existing object error. (Object reference not set to an instance of an object).

I've been trying to figure out a good way to do this but haven't had much
luck, any input would be greatly appreciated.
Basically, after a datagrid is sorted, how can I get the primary key value
of the item selected by the user? That is, not the datagrid index
'location' of the item the user selected, but the value inside a column of
this item the user clicked on.
I would use the CurrencyManager in a windows application but I'm not...

Essentially, InsertAT is broken!
For the past couple of hours, I've been getting this "Parameter name:
'-2147483550' is not a valid value for 'index'." error.
Apparently, its caused by having manually inserted a row in the table
bound to the Combo box. The InsertAt Method of adding a row just does
not work.
Hope this helps anyone with this problem.

I have been searching all over the web for a way to sort a DataGridView based on
the actual text being shown in a ComboBox column as opposed to the underlying
value (an ID in this case). Can anyone tell me if this is even possible, and if
so, how to do it? If this is completely impossible, how would you suggest going
about sorting a ComboBox wherein the text displayed in the column is the
client's name, and the underlying value is an ID?

Hi All,
I am using .net framework 1.1 and c#. I have one problem regarding dataview.
I have one dataview to which sorting may be applied or may not be applied. I have one UI component where I am displaying the dataview. All rows in dataview are displayed in the sequence as they appear in dataview. i.e. there is direct mapping between dataview rows and UI rows.
I have subscribed ColumnChanged event of the datatable on which dataview is...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
