How To Apply Column Alignment To DataGrid
May 19, 2012
I have an VB.Net ASP page that I have a datagrid on it with 5 columns and a few rows of data. The page will show the data and grid just fine. I need to now apply alignment to the datagrid columns.
dgLast5Bills.DataSource = dtBill
dgLast5Bills.DataBind()
dgLast5Bills.Columns(0).ItemStyle.HorizontalAlign = HorizontalAlign.Center
The code above will error out when it hits the line for the alignment.

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 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.

I have written a converter class(implementing IValueConverter) which converts a code that comes from the database (for example "CTY") into a more user friendly description (for example "City"). I want to use the converter on a single Column in my XCeed WPF Datagridcontrol, but I do not know to which property I must set the Converter to. I also tried to attach it to a DataCell using a style but it won't work properly and I think it is also not necessary since the converter should apply to only one column and not every cell.The columns are also autogenerated so if I could apply it at runtime, that would be awesome!I don't know to which property of the column I must aplly the converter to (the Xceed Column doens't have a "Binding" property. Do you guys have any suggestions?More examples or code can be provided if asked for. I hope my problem is a bit clear for you.EDIT:
This are the things I use in my XAML file:
<utils:BudgettaireEntiteitConverter x:Key="BudgettaireEntiteitConverter" />
<xcdg:DataGridCollectionViewSource x:Key="GridViewSourceDefault"

I am trying to the first column in a listview to have right alignment.
I made this test VB in a new Windows form project:
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Dim listview1 As New ListView
listview1.Size = New System.Drawing.Size(210, 210)
listview1.Location = New System.Drawing.Point(10, 10)
Me.Controls.Add(listview1)
listview1.View = View.Details
[Code]...

My first column does not align to center, although the sub-columns aligns perfectly
Listview1.Columns.Add("Column1", 100, HorizontalAlignment.Center)
Listview1.Columns.Add("Column2", 100, HorizontalAlignment.Center)
Listview1.Columns.Add("Column3", 100, HorizontalAlignment.Center)

How could I change the column header of the Data Grid to center or right but not left as default? [We are talking 'bout Data Grid here, recently I always receive answers for Data Grid View instead :( ] I just want to re-align the header only, not the whole column. There's another topic discussed bout this already but it's not working in my case. Here is my code:
Public Class Form1
Private Sub DataGrid1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles DataGrid1.Paint

I have a ScrollBar Template as per below - only relevant portion shown:
<ControlTemplate x:Key="VerticalScrollBar" TargetType="{x:Type ScrollBar}">
<Grid>
<Grid.RowDefinitions>
[code]....
Now the Rectangle Portion:
<Rectangle Height="35" Width="19" Fill="{StaticResource GreenTeaBrush}" Margin="-35" VerticalAlignment="Top"/>
I only want that to show up on DataGrids OR i would like this enter ControlTemplate to only work on the ScrollBars of DataGrids.

Any way to apply some validation rules to the following code?
VB
Private Sub dgOperator_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgOperator.EditingControlShowing
Const cSUBNAME As String = "dg_EditingControlShowing"

Another thing should I be applying this validation on the Id Op'rateur column or when I click to the edit the next column in the datagrid i.e. Description?

I'm new to VB 2008 and was wondering how to apply 2 toned back color to my datagridview column headers or listviews. Where the color is lighter at the top of the column header and then becomes darker towards the bottom of the column header. It seems most apps use them these days.

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?

I came across this great article on creating a custom datagridview column which creates a graph-like effect in the cells of a custom datagridview column:[URL]..Does anyone know how you would edit this to format the number in the cell as a percentage? And does anyone know how you would set this up to take 0 values which do not create any graph effects at all.I have been trying to do this but keep getting errors.

I'd like to get the value of a column from a datagrid and insert that to a table. I get an error "Object reference not set to an instance of an object."
Here's my code:
Imports System.Data.SqlClient
Imports System.Data
Public Class Class1
[Code]....
The thing is -- when I look at table amtdue, everything is actually saved there. I just don't understand why I'm getting the error, and so I can't proceed with what I have to do after clicking the btnaddtocart button.
