View 7 RepliesDataGridView Sorting On Columns Not Working?
Apr 28, 2010I'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...

Error In Sorting Datagridview's Columns?
Oct 7, 2009I 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.
Code:
Dim col As New DataGridViewTextBoxColumn
col.ValueType = GetType(Double)

VS 2005 Datagridview Columns Not Sorting?
Sep 23, 2010I 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.
Adding/removing Datagridview Columns Based On A Combobox?
Oct 26, 2011The user picks x amount of scenarios from the combobox, and x amount of columns appear in the datagridview. If the user changes the number of columns from x amount to y amount, the columns should be added/removed respectively but currently when y amount is chosen x amount of columns are in the datagridview.
I'm not sure how to do this, I've tried using an IF statement under the .SelectedIndexChanged event but the code adds columns until it reaches as high as it can go, then pulls an error saying too many columns.

View 7 RepliesRemoving Duplicates Using 2 Columns In Dgview?
Jun 13, 2012My dgview has some records. But I wanna eliminate the duplicate rows from dgview if the first column and the last column values are same for the rows.in the below image rl1,rl2,rl4 are repeated but the values in ch2 and ch3 are different but still the value in ch4 are same for rl1,rl2,rl4.
so i wanna keep the first instance of rl1,rl2,rl4 displayed at the first time and rest should be removed.
But look rl2 it is case sensitive as the first instance is displayed as rl2 and the second as RL2. But still ignore the case sensitive and should display the result as in dgview2. I am populating from a csv file and it must work for many records.

Use Custom Comparer When Sorting By Multiple Columns?
Apr 7, 2011I 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, 2011I'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"}})

Removing Last Row Datagridview?
Dec 11, 2008Okay I have an unbound DataGridView control which users enter as many records as is required. However I have some validation running which checks all cells to ensure data has been entered, however as you know, as soon as data is entered into a row, another appears, well I need to remove this row.
I can't use

As the row has not been committed, therefore it can't be deleted
Also I need the 'enable adding' on, as without it rows will not appears.

Sorting In Datagridview?
Jan 14, 2010I have two columns in a datagridview, one is a year and the other is a month. These two form a date, but unfortunately the structure in the database I'm forced to use is that of two integers. I need to sort the rows by date, using these two integers. I tried creating an unbound column with a date, but sorting this way seem quite difficult. So, I thought I could do a multicolum sorting by year first and then by month using two columns

View 2 RepliesDataGridView - Selecting Row After Sorting
Sep 29, 2011I have a datagridview that is bound to a dataview. I use a textbox to sort the list of data in the datagridview. Once the list is sorted I want to click on a row to populate the textboxes in order to update the data. Problem is once I sort the data I click on say row 3 and it pulls up the orginal data before the data was sorted in the datagrid view. For instance:
Before Sort:
1. betsy
2. james
3. john
After sort:
1. john
2. james
3. betsy
If I double click row 1 it will pull betsy info into my textboxes instead of john. I currently refresh my datagridview after every letter is entered into my textbox. I also reload my dataview and rebind the dataview with the datagridview.

View 4 RepliesVS 2008 Datagridview Sorting On/off?
Aug 25, 2009win app where user loads files from win explorer into a datatable bound to a datagridview. After loading the files, each filename is parsed and split into different fields and finally sorted w.r.t. to two its columns. One column is filled with error codes and depending on these, the cells that contain errors will be marked redIt's a three-step process where I just described step one.In step 2, the user will edit the data and hopefully correct the errors, cell by cell, according to some rules and here it's where my problems start. Since I sort the table in step one, sorting is activated and each time the user changes a value in one of the sorting columns the table will do a resort, messing up some of the editing done by the program (cell background color etc.) confusing the user.I have tried to use several of the datagridview events (mainly the cell and the row events) and also to turn-off the sorting by setting its dataview.sort="". Neither of my attempts has been complete successful so far.
View 2 RepliesVS 2008 Datagridview; First Row At Top After Sorting?
Nov 2, 2009I need to have "press" grouped (all jobs for press #1 then #2 then #3). Then have the grouped press jobs sorted by date ascending (all Mondays jobs together, Tuesdays jobs, etc.)When I change: Me.~my~BindingSource.Sort = "print date" to Me.~my~BindingSource.Sort = "print date, press"My datagridview groups the press rows together and lists everything in ascending order according to todays date just fine, except it won't show the first job with today's date at the top of grid. It will start somewhere within the today's date entries. I then have to scroll up 4 or 5 rows to see the first job with today's date.
But if I change my PC's calender/clock to any other day (past or future) it works perfect, first job at the top, all presses grouped together. Set clock back to current day and time and again it will start somewhere within the today's date entries.
