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 RepliesHow do i change the column order of a datagridview in code.
View 1 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 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 datagridview which is populated from a datatable. This works fine. But if i run it more then once i get a column name "example" already belongs to this datatable. Ive tried everything to clear all the columns of the datatable and the gridview but still the same

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 2 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.

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.
I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...

Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

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.
View 3 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?
View 4 RepliesI 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 am reading a record from a database into a datagridview.I have changed the column "ComputerAwareness" from a textbox column to a combobox column.This column is at the 21st position in the database but after changing it to a combobox in datagridview it is diplayed as the first column in the datagridview.How can I keep the position of this column same as in the database?I have googled a lot for the solution and tried all the possible ways but none seem to work.One of the ways I tried is in the code below.

I had a DataGridView that was bound to a Table in my typed DataSet. I recentyl added a new column to the table in the database and updated the table in the DataSet accordingly.Now, when I go to the DataGridView to update it, the new column does not appear under the "Databound column" list. I tried setting the data source to "None", then reselecting it. Still, it does not show the new column. I then deleted the DataGridView and re-added it to the form. Again, same result. However, when I select the data source, then click "Preview Data", it show the added column.

For example I have Columns colcase(Combobox), colreportTime(Time)

I'm selecting value from my database, passing it to datatable then giving DataGridView.DataSource value of datatable.The thing is that in those rows i'm also selecting some dates and problem is that my default date in database is '1900-01-01 00:00:00' because i use "smalldatetime". And what i want is this...when I find default value in database i want to show it like an empty string, like i said...because date is in smalldatetime format i can't do this in SQL query so i wonder how can I change this in DataTable or even better in DataGridView...of course, in code?
View 4 RepliesTwo quick questions about datagridviews... I have an unbound dgv and I'm trying to do some simple formatting but sadly my .net knowledge is limited at best. I'm trying to make a balance sheet and I need to do two things:
1. How can I set row(d) to sum row(a:c) for each column (for multiple years of financials)
2. Is there anyway to not only make a row readonly, but make in unselectable (to skip totaled rows)?
I have a datagrid bound to a datatable. The datatable will then be written to an xml file using the built in "WriteXML" function, which is sweet!
What I would like to do is update the table then overrite the existing XMl file when a cell value changes.
The problem is the "CellValueChanged" event is fired before changes are actually committed to the dataset. I do not want to use the "CellValidated" event because it will fire for each row when the file is forst loaded into the dataset and displayed in the datagrid.
I searched for this topic and all the examples are in C# (and they have errors as they will not convert with a C# to VB converter). I am using VB.net 2005 and would like a sample that work for it. I have a loop that goes thru the DataGridView and changes the row color based on a column/cell value from the binded DataTable (shown below). I'd like to add to the loop (where the comment is) and also hide the button for this cell and let the "In Process" show in the cell instead.
Private Sub ColorInProcessItems()
