VS/VB 2010 - Sorting Excel Rows Getting Error "The Sort Method Is Not Valid'?
Jun 14, 2011
In the following code all goes well until the .Sort line. Then I get an error which says, "The sort method is not valid. Make sure it is within the data you want to sort and the first sort by box isn't the same or blank."I've tried various permutations to deal with this exception, all to no avail. The Range is Selected ok and the Excel data are pasted from the clip board ok. Then I get the error and no sort occurs.
When ever I try to update a record from data grid using a dataAdapter record it always showing ' update requires a valid insert command when passed data row collection with new rows' From specific sql server Table only. Resulting me holding up a project.

I need to sort datagridview row sorting. There two color in the datagridview rows, some is yellow, some is white. How can I sort them by yellow rows shown first then only show white color rows?
I have a slightly odd problem that I think is most likely due to an act of foolishness on my part, but for the life of me I (and other members of my team) can't see it.I have an object that contains a generic list property which I would like to sort. I have written a comparer class to do this for me and I am calling it in the following way:baseObject.ListOfThings.Sort(new ThingComparer()I have debugged into my compare function and it is returning the right values.However After the sort call, the list remains unchanged. Have I missed something obvious, or is there something else I need to do.EDIT: Yes I was being a fool, and the property returning a list was recreating it from scratch each time it was accessed
I have a vb.net app that I can read a .xls file into a dataset or loop through as oledbdatareader and it gives the same result.Some of the rows have all nulls when I loop through them but if I open the same file in Microsoft Excel I can see that row fine.[code]From the info above the first two SKU values would come through fine but when I get to the 3rd row it would show a null.Is it possible that it kind of inherits the first rows type and since the 3rd row isn't all numeric if nulls it? [code]

I'm using a Listview in VirtualMode, so I can 'add' a lot of files almost instantly. A Listview in VirtualMode does not allow sorting, so I need to sort the data myself. The data is stored as a List of Structure (it's faster to load than a List of ListViewItem). The code below works fine, but I need to sort based on multiple variables in the Structure. Code:
I am trying to sort my report on the values in a column. The underlying query consists of a director colum a movietitle column and a rating column, for every movie a director has directed there is a record which off course shows the rating in the ratingcolumn In my report I have grouped by Director and created two other columns which are called: Nr of Films and averageRating. in the design view i used two functions to accomplish this. the first is: count('the field of the rating') and sum('the field of the rating')/count('the field of the rating'). This is working... but now I would like to sort the column, Nr of Films. I think I have to do this with interactive sort of the textbox which holds the column name(i.e. Nr of Films)

I need to sort the rows in a bindingsource. When I sort by a field name, ASC, it works correctly, but when I sort in DESC mode, instead of being the opposite of ASC, it sorts the rows whose fields have the same value in ASC order. For example:
I've got a column with the values A, B, P, P, P and P ASC: A B P(1) P(2) P(3) P(4) DESC (as i want it to be): P(4) P(3) P(2) P(1) B A DESC (as it sorts):P(1) P(2) P(3) P(4) B A
Is there any property in bindingsource which I can use to change this?
