I have this strange phenomena in which I load an Excel file. The Excel file consists of data arrange in columns having a column header. Once some computation is performed and another file is loaded into the datagrid, the column order of the new file changes .i.e the column header is changes its position from its original Excel file.

View 3 RepliesI have an application with various datagrids. I have a specific need for the order of the columns (which I set at design time) but for some reason Visual Studio regularly changes the order of my columns on me when opening the project is VS. So, every time I compile I have to go make sure the columns are still in the correct order. Sometimes they are, sometimes they aren't.
I remember this same behavior in 2002/03 version of Visual Studio with tabs and tab order. If it makes a difference, these datagrids are created at design time with LINQ2SQL Data Sources. I did this all the time with VS2008 and never noticed this behavior.
How do i change the column order of a datagridview in code.
View 1 RepliesI have a datagrid that I am unable to change the width setting, it always reverts back to the original setting.
To change this setting:
1. select the datagrid view tasks
2. Edit columns bound column properties
3. Select Width property
4. Width property will always revert back to the original setting.
I have check the properties settings without any luck.
I'm retooling an app, and condensing my queries down to one, but to do so, I would like to move the columns for better presentation. I am reporting on errors for particlular equipment, and the user may want to get equipment by errors or errors by equipment. Is there any way to change column order?
View 5 RepliesI have a DGV.It has some columns.The columns are in the correct order e.g. 1,2,3,4 at design time.When I start debugging and then come back to VS, the order of the columns have changed and I have to put them back in the correct order everytime.After some testing I have realised it only occurs if
1) I make a change on the form that holds the DGV
2)Leave the form open in VS while I play the application ie. debug.

I have a datagrid that I am populating from an Access 2000 query in Visual Basic 2008.
This code works fine:
With dgvCollections
.Columns(0).Visible = False
.Columns(1).Width = 235
.Columns(2).Width = 230
.Columns(3).Width = 220
.Columns(4).Width = 70
.Columns(4).HeaderText = "Loan"
End With
The query works fine, except that I want to change the alignment for one of the columns. I tried to add this line before the "End With":
.Columns(4).DefaultCellStyle.Alignment.MiddleCenter()
Which causes the error:
"Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated."
And this error:
"Expression is not a method."
I have a datagrid on my form that has a dataset bound to it via the datagrid properties Tables collection. I have the PreferredColumnWidth property of the datagrid set to 75. How can I change the column width in code to match my column header text?
View 4 RepliesI am trying to change the datagrid cellstyle alignment of a column in the designer. I set it to middle right but then I run it and it still aligned to the left. I have a lot of datagrids in my application but there are few that doesn't accept any alignment settings which I don't understand at all, can't see any reason, I been looking through the options if there is anything but can't find anything. I just need one column of cells to be aligned to the right whatever I do all of the columns are aligned left and there is an option in the defaultcellstyle that is sat to middle left, but when I try to change it to Not Set it doesn't change.
View 6 RepliesI have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?
View 2 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

I have the following code to get the column names from my Microsoft Access database.THE PROBLEM is that the stupid thing orders it alphabetically for me. How do I get it to put the columns in order the way they are in the database?[code]I've also tried a different approach with a string array and for loop to "make it" go to the beginning, but proves my point that its stupid enough to order it for me.

View 6 RepliesI have a listview1 with two columns Name and Age. This code when I click on a listview item it is higlited and then i click on textbox1 it will remove the row and place the text in textbox1 and textbox2. Then when I double click on textbox1, it will add the text back into listview1 at the bottom of the list. I want to place the two columns at the same place it came out of. EXAMPLE: click on Tom - textbox1 has Tom in it and textbox2 has 2 in it. When I double click on Tom then it adds both Tom and 2 in the listview at the bottom

Sometimes I select a value in my Combobox by hand, and sometimes the value to show is chosen elsewhere in my program logic. I want to carry out a certain action only when I have chosen a value by hand, and not when the value is changed by the program. For this reason I use the DropDownClosed event (and not, for example, SelectedValueChanged or SelectedIndexChanged). This works fine, but if I set AutoCompleteMode of my Combobox to Suggest, selecting a value from the suggested list doesn't fire the DropDownClosed event (perhaps logical, as the actual drop down list doesn't actually open).
View 2 RepliesI am using a modal form with a datagridview in order to populate textboxes on a parent form. The datagridview is bound to an anonymous type resulting from a linq query, which varies depending on the textbox control whose keypress event is called. I always want to display a key value in column 0 of the datagridview (along with a variable number of additional columns), and then use that key value once the user selects a row.
However, when setting an anonymous type from a linq query as the datasource for a datagridview control, the columns are indexed alphabetically rather than in the sequence selected in the query. This requires setting the displayindex as a workaround, and then keeping track of which column contains my key value. I read elsewhere that this was something fixed in VS2008 SP1, but I still encounter the behavior.
It is not so hard to get the field names from a database via GetOleDbSchemaTable and OleDbSchemaGuid.Columns. It works fine. The field names come i alphabetical order though. I really need them in the correct field no order.
Used code:
connection.Open()
Dim schemaTable As DataTable = _
connection.GetOleDbSchemaTable(OleDbSchemaGuid.Columns, New Object() {Nothing, Nothing, tblname, Nothing})

View 2 RepliesI have several forms that have a DataGridView object in them. I recently discovered the AllowUserToOrderColumns attribute. I set it to true and I can reorder the columns at will. The problem is that the order for these columns is lost once the form is closed. Ok, how do you save the order for these columns and then restore them to the form once it has been reopened?
