I need to be able to sort a DGV image column by clicking on its header. I set the sort mode to automatic in the designer, but when I click on the header nothing happens. Are these columns sortable? If so, what do I need to do?
View 5 RepliesI'm trying to sort multple colums in the DataGridView which is unbound. I would prefer to sort by using a DataTable/DataView but for some reason another developer in my team experienced other problems relating to sorting so he abandoned using the DataTable to fill the grid :(
Here is the senario: I want the user to be able to choose which columns they want sort on. The way I envisaged was to show a form with a listbox, a grid and 3 buttons (Add to sort, Remove from sort and Apply Sort).
The list box would be populated from the parent form grid column headings.
The grid will show the columns and sort direction.
Button 1 would add the selected item of the list box to the grid.
Button 2 would remove from the grid the selected row.
Button 3 would Apply the Sort in the order of the grid and the columns SortDirection.
Now I looked at How to: Customize Sorting in the Windows Forms DataGridView Control using the IComparer [URL]
how I can use the IComparer to sort on multiple columns that a user has specified or another way to sort on multiple columns using unbound data.
I have an unbound datagridview that I populate with data. When the user clicks on the column head the datagridview is sorted - which is fine for alphabetic fields but I have a column that contains numeric fields and goes from -100 to +100. This is sorted incorrectly by the number (all the 1s first then all the 2s and so on, ignoring the minus sign). How do I get it to sort my column numerically?
View 9 RepliesI have a datagridview with a column called "Total Price". This is set to a string value type because I need to always show 2 decimals. For example:
4,3
must be in the datagridviewcolumn:
4,30
So I use string.format for this. However, now I have a problem with sorting because the column is a string value type and numbers get sorted like this:
50
4000
40
300
30
20
10000

Is there any possibility to sort multiple columns and group the data by a specific column..
I have a DataTable in a DataGridView, one of the columns has data that I want sorted. I can click on the column header to sort it and it's fine. The problem is that I don't want that column sorted automatically when some of the data changes in it. I want it sorted only when I click on the header.

I have a datagridview on a form with a date column. (column0)
I am trying to sort this by date desending but it will only sort by the day (dd) and not the whole date (dd/mm/yyyy) which leaves the months unsorted.

Is there a way to add an image to a column that also contains text? preferably one from an imagelist control..
View 3 RepliesHow to add an image to DataGridView column?
View 2 RepliesAt runtime, I am adding a DataGridView to a windows form. The final column is a DataGridViewImageColumn:
Dim InfoIconColumn As New DataGridViewImageColumn
MyDataGridView.Columns.Insert(MyDataGridView.Columns.Count, InfoIconColumn)
Adding the following code will get my Information Icon (bitmap) to display in each of the column cells but NOT the column header:
Dim InfoIcon As New Bitmap("C:MyPathInfoIcon.bmp")
InfoIconColumn.Image = InfoIcon
Also, it is worth noting that the image displays 'perfectly' in the cells i.e. it is sized correctly to fit the cell.
However, I cannot find a way to add the same image to the column header cell. After some googling I used the following code which placed the image in the header cell but left me with two problems:
The image did not 'auto-size' to the column headercell in the same way it did when added to the column cells. The image was slightly larger and blurred.
By using the _CellPainting event slowed down performance i.e. when hovering over the DataGridView to highlight the selected row the highlighting lagged behind where my mouse was placed.
Here is the code:

Does anybody know of a way to solve my problem and get a nicely sized, sharp image into a DataGridViewImageColumn headercell at runtime?
I have a SQL database, with some "status" strings. For every status I need to display a .bmp image .
I'm displaying the data from the database via DataGridView with LINQ. In order to display the DGV I have this code:
Me.MyTableAdapter.Fill(Me.TestdbDataSet.MyStatusList)
I was thinking to add another column named "Symbol" and based on the "Status" column to format the cells of the "Symbol" column to display an image.
I edited the DGV, and add a new image column.
I created a directory in my solution called "references" where I put all the .bmp files
I don't know how to do this. My first thought was to put an expression in the DataTable Properties, but I didn't manage to make that work. Another way is to format the cells in the "Symbol" column, and again I don't know how to do that. I tried with "Select Case ... Case ... End Select" with no success.
LE: Should I Insert the .bmp files into SQL database (varbinary(MAX)) If yes, how?
Problem: Calling a method which uses a cell's value from a DataBound DataGridView. Works as desired without adding an image column.When I add the image column, the method attempts to use the value from column 1 instead of column 2, as the code in the 2nd method below ("findSign") states:

I have a datagridview which is bounded to a table m_table constructed in my code. A column named price has decimal type.
DGV.DataSource = m_table
DGV.Columns(columnPrice).ValueType = System.Type.GetType("System.Decimal")
All prices are in decimal. But I found that when clicking the column header of DGV, the price column is sorted like a string. For example:
9.0, 13.5, 8->13.5, 8, 9.0
But I want sort numerically, that is 8,9.0,13.5
I wonder why decimal type cannot be sorted numerically. How to achieve this?

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.
