Change Order Of The Columns Read From Database Into A Datagridview?
Jun 30, 2012
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.
Private Sub DisplayButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DisplayButton.Click
Dim cs As String = "Provider=Microsoft.ACE.OLEDB.12.0 ;Data Source=C:\Users
How to change the font color of the column header text in my datagridview if the entire column is read-only. I basically use a loop to add columns to my datagridview and then set the properties of the columns. But for some reason setting the DefaultCellStyle.ForeColor and HeaderCell.Style.ForeColor properties does not work. The header text is still black.[code]...
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]
I 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.
I have a dgv with 5 columns (combos) added with the wizard, then in the form constructor i set the datasource, value member, displaymember and datapropertyname for each one, after this i fill the main data table and set the dgv datasource with it.If i just do this and don't use the display index, the columns show in an wired order, doesn't show up like i defined in the wizard neither in the order of the sql statement.
For example, i add this columns (names): B,C,E Then if i use this select statement
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.
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]
I 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.
Code: Private Sub UpcomingInspections() AddHandler mAdapter.ErrorOccured, AddressOf HandleDataError
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 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 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......?
Public Sub gererateReport(ByVal dg As DataGridView) Dim oExcel As Excel.Application Dim oBook As Excel.Workbook Dim oSheet As Excel.Worksheet Dim oMissing As Object = System.Reflection.Missing.Value [Code] .....
I need a few columns in my datagridview to have the font be aligned to the right, but no matter what code I use it doesnt work.
I would also like my columns with numbers to always have 2 decimals.
And lastly I would like the right side of the column header to be blank and not movable. I can do this by adding another column to my table with a blank name and then set the width to fill, but the problem is I can just move this around, which is not good, I want to freeze it so it looks good. I do want to be able to move around on the other columns, just not this one. Unless there is another way to do that?
I have a DataGridView that has been dragged over from the DataSource Tab. All works good.I need to have the background color of some of the cells changed based on other columns in that same row. Such as, have the background color of a cell Red if the Status column (not shown) relates to 90 days overdue. The next row may be different.
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?
easy way to simply load the data from database into a datagridview with one of the columns being a comboboxcolumn. Apparently there is no selectedvalue, selectedindex or value as in a combobox to return the combobox value. What I need is to verify if the database value is 'true' and if it is then I need to set the comboboxcolumn with a specific value.
Ex:
if ds.tables(0).rows(0)("flag") = "true" then datagridcolumn.selectedvalue = 1 else datagridcolumn.selectedvalue = 0 end if
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 am filling a datagridview with multiple columns from my oracle database. It has become necessary that I add a column with a checkbox. I figured this out.
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?
I 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.
I am using the following code to alter an table imported from an Excel spreadsheet
Dim SQL As String = "ALTER TABLE receipts ADD payee integer, account integer, category integer, reconciled boolean" Dim dataread As New OleDb.OleDbCommand() dataread.Connection = Connection1
[code]....
Both ExecuteNonQuery() actions yields the exception message {"Syntax error in field definition."}The error message does not happen with the first if the boolean column is not there (I tried Tes/No as a definition - but that also failed.The second query to modify the ID column from autonumber to integer I assume fails because it is a Primary KeyHas?
I'm trying to write small piece of code in Visual Studio (VB.net) that will change value of a particular field of the database for all highlightetd rows. So, I'm running my form, which displays some data from the datatabse. I then highlight some rows (holding Ctrl and clicking). Next I click a button that will trigger a value change for all the highlighted rows (only). Say, I want to change the "Name" column's value for all of them.
I'm trying to add a datagridview in vb.net, but it does not allow me to change the connection string or the database that should be imported to connect to it. The only thing that I'm seeing is the previous ms sql database that I connected with datagridview and everytime I click the new connection, the window closes and it leaves me with the datagridview with the previous connection that I have. And its not applicable because, now I want to connect it with mysql. Not ms sql. Its some sort of a cache like feature in vb.net, how do I get rid of it. so that I can add the new connection for mysql? Do I need to reinstall visual studio 2008?
I have a text box in which you enter last name first and first name last ex. (wojo casey) and I would like to change it so the output states Casey wojo
