DataGridView Sorting On Columns Not Working?

Apr 28, 2010

I'm using vb 2005, seems sorting is not working if I change the data by code. For example, if I have a simple form with only one datagridview and one button, grid was sorted on column 1, then I press the button to randomly change data in column 2, then use column 2 to sort, the display order is not correct, but after the button click, if I click on a cell, the grid will re-sort by itself, and get the right list. I know DataGridView is not for Editing data...

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim dt As New DataTable
[Code] .....

Error In Sorting Datagridview's Columns?

Oct 7, 2009

I have a datagridview and all its columns are set to Double Datatype. The problem is when I changed the value of cell and try to sort the column, it shows me an error "Object must be of type Double." I check each cell but all its values are number and I can sort all the columns before I edit one cell. But when I tried to change the value of only one cell and sort the columns, the errors will show. Its weird because I only removed 1 digit of the cell value and I cant sort at all.

Dim col As New DataGridViewTextBoxColumn
col.ValueType = GetType(Double)

VS 2005 Datagridview Columns Not Sorting?

Sep 23, 2010

I have a datagridview that is bound to a datatable. When the form is displayed, the column headers have no sort glyphs and the columns will not sort.

I don't see a property on the form that controls column sorting - at least not one that's obvious. This is an area of the code that another developer wrote originally, so maybe there's something going on that I'm not aware of.

Use Custom Comparer When Sorting By Multiple Columns?

Apr 7, 2011

I have a ListView (GridView) that I want to sort by 2 columns, so if 2+ items have the same value in Column 1, it sorts by Column 2. Pretty easy. But empty strings show up at the top when sorting A-Z. I'd like to move them to the bottom. I made a comparer (IComparer) that takes care of this, but I'm not sure how to use it.[code]...

Combing Multiple Columns For Sorting With Generic Member Expressions

May 20, 2011

I've followed examples here and here to create a generic sort with memberexpressions, but how I'm supposed to add a "ThenBy" clause, or combine multiple columns for sorting in the methodcallexpression. Ideally, the ThenBy should go before skip, but it can't because it can't see the orderby clause that I made with the methodcallexpression. GridSortExpression is a Telerik class - it just describes which column and direction the query should be sorted.

Here is what I have right now:
Dim exp As Expressions.Expression(Of Func(Of Product_Catalog, Boolean)) = PredicateBuilder.True(Of Product_Catalog)()
exp = exp.And(Function(e) e.Chapter_Price > 30)
Dim sortExpression As New List(Of GridSortExpression)({New GridSortExpression() With {.SortOrder = GridSortOrder.Descending, .FieldName = "Id"}})
[Code] .....

Sorting A Listview Which Is Not Visible

Mar 26, 2009

I use a listview control which is created at runtime because I don't need it visible to the user. I basically use it to store some information about paths, sort it and then pick out the data I need. It works very well apart from it doesn't seem to sort. For efficiency, I turn off sorting on the listview while the data is being added then enable sorting on the listview at the end. However, the sorting doesn't work. Is this because the listview isn't visible or am I just being daft?

Original DataTable Object Has Columns Added When Variable Has Columns Added?

Oct 6, 2011

I have a datatable property called prpParametersTable in a class called clsBatch.  I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem.  When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why?  I only want to add the three columns to dtP and not prpParametersTable.  How can I do that?

Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String
' set new columns that have BatchID, Insert DateTime, and UserID for the SQLBulkCopy method below
Dim clm As DataColumn
Dim dtP As DataTable = clsBatch.prpParametersTable

ListView With Names - Sorting Awarded Scores?

Jan 18, 2011

I have a routine whereby kids do some tests and are awarded scores. These scores are put in a ListView with their names. The snag arises when sorting! It's ok in single figures but at 10 and over it is no go! It is only in the first column that the scores are put. I believe the method is in collections and compares - am I right? So how can this be simply done? In all the bits of code I've managed to get hold of I get lots of words underlined in blue and have no idea what the explanations mean. Some such things are, "IComparer".

Sorting Data From .text File In Listview?

Mar 9, 2012

I'm using Visual Basic Express 2008 and I need to upload and sort two data text files (notepad) in a listview box. It doesn't have to be a listview box I chose that because it has nice options for columns. Anyway I've got the code set up to open the dialog box and allow the upload of multiple files. I've also got it set up to show separate columns, movie titles and box office amounts, titles in one file box office amount in the other. What I nee sorting the data once it's uploaded so the movie titles show in one column and the box office amounts show in another. Currently everything is showing in the left most column. I'd like to be able to represent the data seperately also so I can format the dollar amounts into currency. Here's what I've got so far:

Private Sub LoadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadButton.Click
Dim DialogBoxResults As System.Windows.Forms.OpenFileDialog

Sorting Objects In Arraylist By One Of The Object's Properties?

Aug 30, 2011

I have a group of objects stored in an arraylist. These custom type objects have a number of properties from their underlying class . I want to use one of the properties to sort the array. I cannot determine which Array.Sort method to use.

I want to sort based on an integer property. Virtually every example I can find involves sorting strings.

So, assume the Objects have the following properties. as string
Obj.ID as integer
Obj.Alive as boolean

The objects are kept in an arraylist called FriendsOfMine.

I want to be able to order the list by Obj.ID, both ascending and descending in value.

Sorting A Dataview Object Based On A Column Number?

May 10, 2011

I have a dataview object that is being populated by database fields - so I can sort on these partulular columns by specifying the actual column names without any difficulty. However, I have been asked to add a few more columns to the dataview, and these columns will be calculated columns, not directly derived from an underlying database column.The users want to be able to sort on these new columns as well - even though there is no actual column name I can use to sort.

I have not been able to see where I can sort a dataview based on the actual column integer value used when the user clicks the appropriate heading to sort.

Sorting A List Based On An ArrayList Within A Custom Object

May 24, 2010

I am using a list to keep track of a number of custom Row objects as follows:

Public Rows As List(Of Row)()
Row has 2 properties, Key (a String) and Cells (an ArrayList).

I need to be able to sort each Row within Rows based on a developer defined index of the Cells ArrayList.

So for example based on the following Rows

Row1.Cells = ("b", "12")
Row2.Cells = ("a", "23")

Rows.Sort(0) would result in Row2 being first in the Rows list. What would be the best way of going about implementing this?

VS 2010 Search Listview: Object Reference Not Set To An Instance Of An Object?

I'm using the following code to try and search a listview (I got it from msdn):

Dim atem As New ListViewItem = ListView1.FindItemWithText(TextBox2.Text, True, 0, True)

If atem IsNot Nothing Then
ListView1.TopItem = atem
End If

Then I got the " Object reference not set to an instance of an object" error highlighting the following line: ListView1.TopItem = atem So then I tried this:

Dim atem As New ListViewItem atem = ListView1.FindItemWithText(TextBox2.Text, True, 0, True)

If atem IsNot Nothing Then ListView1.TopItem = atem End If it still isn't working.
