I have a datagrid, I am filling it with LINQ as well as a custom class to add data to it.Afterwards, I need the data in a specific order - it seems to ignore me.How do I change a columns properties, like index etc??[code]
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 would i change the order the colums with drag and drop[code]...
View 1 RepliesI 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 binded a datagridview with datasource, But its order was changed then I used Columns("ColumnName").DisplayIndex property to arrange the columns of DatagridView. Now I am exporting this DataGridView to Excel, All things are right but problem is about the column positioning, Columns in excel file are shown in wrong order (it shows order before I applied Columns("ColumnName").DisplayIndex property to arrange the columns of DatagridView). My question is that how I permanently change the Column index of DataGridView......?

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 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?

For example, i add this columns (names):

I have a form containing a datagridview and a groupbox containing 2 radiobuttons.If radiobutton 1 is selected only the order headers are shown.If radiobutton 2 is selected only the orderlines are shown.There also is a button called "show". When clicked the dgv gets filled with data.When I first select radiobutton 2 (orderlines) and I press the show button the columns in the DGV are in the right order (as shown in the code "strview").If I select radiobutton 1 still the columns are in the right order.HOWEVER...when I now select radiobutton 2 the order of the columns get all messed up.

I'm still trying to get my head around the whole "Lambda Expressions" thing.
Can anyone here give me an example ordering by multiple columns using VB.Net and Linq-to-SQL using a lambda expression?
Here is my existing code, which returns an ordered list using a single-column to order the results:
Return _dbContext.WebCategories.OrderBy(Function(c As WebCategory) c.DisplayOrder).ToList
Note: The WebCategory object has a child WebPage object (based on a foreign key). I'd like to order by WebPage.DisplayOrder first, then by WebCategory.DisplayOrder.
I tried chaining the order bys, like below, and though it compiled and ran, it didn't seem to return the data in the order I wanted.
Return _dbContext.WebCategories.OrderBy(Function(c As WebCategory) c.DisplayOrder).OrderBy(Function(c As WebCategory) c.WebPage.DisplayOrder).ToList
I am using LINQ queries inside a WCF service to return data to a Silverlight frontend. Problem is the columns being returned using LINQ are in alphabetical order and I want them the way they are ordered in the database instead. Does anyone know how to stop the alphabetical ordering of column names?
View 4 RepliesI use Visual Studio 2010 and SQL Server 2008 R2. I have created an Entity Model in a class library which I have referenced in a VB Winforms project. I created a data source in the project based on the entity model in the dll. However, all columns in the data source are listed in alphabetical order instead of the native order from the SQL Server database. I cannot locate the cause of this as much as I try.
This might not seem a huge problem, but it is costing me valuable time in rearranging controls dragged to forms and reindexing their tabstop indexes.
When user clicks on a button on my form, it sends the datagridview on that form to another class that [basically] does a bunch of stuff and shows a dialog with a print preview. Everything works perfectly fine, except that if a user switches around columns it won't print them in that current order. For example, if user moves the LastName column before FirstName column, then it should print in that order, but it prints in the column order that the datagridview was originally loaded. The dgv1, is the datagridview that was originally loaded, not the current one. [Code]
View 10 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.

View 5 RepliesHow can I set up my WPF datagrid to sort on multiple columns similar to having two sortable columns, clicking on the header of the first column for a primary sort and then SHIFT clicking on the header of the second column for a secondary sort. I would like the multiple column sort to happen automatically when the user clicks on the header of the first column without having to SHIFT click on the second column header. Is there a way to do this entirely in the xaml? If not how can I do this in the code behind? Currently using VB.Net but a C# snippet is acceptable if you have one.

I am using DataGrid control in VB. I have created a DataTable at runtime and added 5 columns in this Datatable. I binded the data table with DataGrid control.
Width of DataGrid is 880. The default width of 5 columns of data table in DataGrid is 100. So for 5 columns width used = 500. So an empty space of 380 left at the right hand cornor of DataGrid. I want to fill this empty space with these 5 columns. I want to increase the width of columns so that it fully covered in DataGrid.
I'm in the process of converting an app to vb.net 2008. I was using an msflexgrid previously. I am not using a database to fill the datagrid but as the application recieves data via a tcp connection I place the data into the datagrid's columns. The problem I am having is with column widths. I found this code by doing a search on here and added to my form.
