I 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.

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).

I 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.

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?

I have an unbound datagridview that has 2 columns. Both columns contain numeric data only and will only go to 55 in count. How do you sort a Datagridview Column in collating sequence? I basically want to sort from 55 down to 1 and 1 to 55 in their respective numerical order.

I 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?

I 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 datagridview with 4 columns (bound to a datasource).The following code ensures only numbers can be typed in the first column, all but numbers in the 2nd column, and only letters in the 3rd and 4th cooumn. It also converts the input in column 3 and 4 to capital letters.
Private Sub validatekeypress0(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
If Asc(e.KeyChar) <> 13 AndAlso Asc(e.KeyChar) <> 8 AndAlso Not IsNumeric(e.KeyChar) Then
e.Handled = True
[code]...
The problem I have is that the user still has the possibility to place restricted characters in a column by pasting them in (with ctrl+v or right click-->paste), because the keypress doesn't notice the pasting.What should I do to make it impossible for the user to use restricted characters? In other words, how can i check the text the user wants to paste in a cell (cause that's the only other way to input data I can imagine)

Using VB.net and the following LINQ statement. I suspect the "Order by" does not work with Concat(). I want to list the current item the user has and then list more available items in asending order. So first i select the current item from the db and then select the next available items in order. LINQ is ignoring the order by statement and sorting by the PK (which is itemID) I examined the list immediately after executing the statement. When I break up the statement and do them separately they work as predicted.
(From items In myDatabase.ItemAssignments _
Where items.BuildingID = buildingID _
And items.ResidentID = ResidentID _

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.

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.

I 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

i am curious and also would like to know how to duplicate this user interface feature in Windows 7. I am aware that if you attempt to sort a column in Windows XP, there is no up/down arrow in the column.
Please have a look at [URL]...It shows part of the task manager process list, and image name column is sorted in descending order.What i am trying to find out is how is the arrow pointing downwards (representing descending) is created.
Am i able to reproduce this "arrow pointing downwards" in VS 2005?

It 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?
