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.
Is it possible to sort a datagridview by column when a user clicks a column header? I have the sort method set to automatic under each column, which from what I read, is what I need. I know this has to be insanely easy....
View 7 RepliesIs it possible to remove from a datagrid view very first "column" i.e. the row selector and also to remove the ability to reorder the columns ?
View 3 RepliesI'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...

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

I have an unbound datagridview with a whole bunch of columns.I need to sort based on 4 columns, the first three are simple strings, the fouth is a date string (which in itself presents a problem, since it wants to sort lexically but I need them in date order).
View 3 RepliesAll fields from my class objects are added to the columns collection of DataGridViews, when the forms or custom controls that contain them are viewed within the VS 2005 designer.

View 6 RepliesI have a datagridview that I'm populating from a SProc. The data coms back fine and is presenting in the DGV without any trouble, but I don't like the order the data is being returned in.A long solution might be to modify the SProc to return the data in a different order, but I prefer to handle this on the UI for simplicity. Also, I know the user can re-order but that presents a specific poblem in the way the columns are structured.Is there a way to programmatically change the order at runtime?Here's the ode I have on the UI. If you need to see the adapter class also, please let me know and I'll present it, too.

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.

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"}})

I 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 RepliesI 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.
How do i deactivate sorting in my dgv after a certain button is clicked?
