How To Click Row Header To Sort DataGridView
Feb 27, 2011Basically, I need to be able to click a row header to sort a datagridview, similar to how clicking a column performs a sort.
View 7 RepliesBasically, I need to be able to click a row header to sort a datagridview, similar to how clicking a column performs a sort.
View 7 RepliesIt 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?

A datagridview is sorting numerical values (when clicking the datagridview column header text) in the wrong order based on the initial digit:

I have a DataGridView with SelectionMode = "CellSelect". I do this because I want the user to be able to click the Column Header and drag the column to a different DisplayIndex. They move the column by clicking and holding down the left mouse button, then moving the column. I also want the user to be able to click the column header and all the cells in the column would be selected. But if I change the SelectionMode property to "FullColumnSelect" or "ColumnHeaderSelect" the user can no longer move the column.In the code below, I can select all the cells in the DataGridView just fine, but I can't select all cells in a particular Column or Row.

I am binding a data set to a GridView in VB .net. I have some custom sorting setup, and want to display an icon next to the header if one of my 3 options is selected.
I've read a lot of methods in doing this, and I see Gridviews even have a ASC and DESC header style I can associate with the view. I have 2 problems with this, though:I am sorting a List with linq on Sort Trigger, then binding it to the datagrid.
The reason I do it this way, is I want to maintain multiple sort levels, ordering by 3 columns rather than 1.
Edit for clarity Specifically what I want to do is loop through the value of a GridView's Header text, see if it matches what I have saved in viewstate, and if so add an image for that header in particular. Something essentially like below, however headerRow.Cells(y).Text is always returning "", even when the header has text:
Sub gvPatronData_RowCreated(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
Dim savedSortDirection(), savedSortColumn() As String
Dim headerRow As GridViewRow = gvPatronData.HeaderRow

I have a VB 2008 connected to my localhost SQL using DataGridview, BindingSource and DataTable. All works fine, i can add, edit and delete the row and the SQL database is also affected.
However, there is one thing that bugs me, that is sorting.
Problem My table in this database is still quite empty, it only has 6 rows
However, if I spam-click the column header, the sorting seems taking some time to sort, so that, the sorting result does not follow my mouse spam-clickings
Note: Spam Click = Clicking the mouse button in high frequency, something like click click click click click click click click click, etc
I then make a debug button to check this
Variables:
Dim DebugInt As Integer = 0
Dim bs As New BindingSource

how do I get the Header text of the header the user clicked in the datagridview.I know I have to use the column header click event but I can't work out or find away to extract the clicked header data?
View 4 RepliesI have a listview that has multiple columns. I am wanting to sort these columns when clicking on the column header.I see there is a sort function, but am not having much luck in using it.How can i sort my listview when clicking on the column header?
View 4 RepliesI have a DGV that is populated at run time from a db query. One of the columns is sorted ascending and the column header for this column displays the little "up arrow" thing to signify it is sorted. I do not want the user to be able to click this (or any other column header) in this datagridview.
How can I maintain the column's visibility but disable the click function?
I have a few classes, one is a form, the other is the source of the datagridview. I want to be able to sort the columns of the datagridview by clicking on the header. Here are the classes that I am dealing with:

Public Class ViewDiscoveryFlashCards
Private DBBindingSource As New BindingSource

I have forms in my application that I want always with same size, I define the border style to fixed tool, disabled the control box. But if the user double click in the form header the form gets maximized. There's some way to disabled this?
View 5 Replieshow would you sort out two columns so when you click them, it either sorts the listed items in Ascending/Descending order. I have named Name column to colName and Mobile column to colMobile
View 10 RepliesI have an application where a datagridview is used to display some data, a datatable is bounded to it, and I want to put some text in the front of some rows to indicate that they are different from others. My code checks the rows and used the following
mydatagridview.Rows.Item(iCnt).HeaderCell.Value = "A"
To set the row header values, it was fine when the data was first loaded. However, when I sort the datagridview by clicking the column header, these rowheadercell values disappear. How to keep the row header values after the sorting?
I have coded my program so that when a user clicks on a column, the data is sorted in ascending/descending order.When I go to click on a column header, however, nothing actually happens.I dont get an error or anything.Here is the code that I am using to sort the records in the GridView:
Property GridViewSortDirection() As SortDirection
Get
If IsNothing(ViewState.Item("GridViewSortDirection")) Then
Return SortDirection.Descending

Right, I'm trying to sort a WPF listbox when a button is clicked, preferrably in pure xaml (otherwise VB). I'm having a hard time seeing as most samples are written in C#. Here's my code:
<Grid.Resources>
<CollectionViewSource x:Key="myCollectionView"
Source="{Binding Path=Query4, Source={x:Static Application.Current}}" >
<CollectionViewSource.SortDescriptions>
[Code]....
Now when this button is clicked, I'd like the listbox to sort by the field "First Name", I assume I have to change the sort description somehow? Again preferabbly in XAML, but if need be in VB could you try and keep it simple
I am using vb.net 2005. I want one clarification for datagridview.I use the following property to set the alignment of header text:
DataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomCenter

I am using following codes to format datagridview column headers, that works fine. My questions are
1) how to make all headings bold? (bold header row)
2) how to apply specific font to heading row
3) how to apply specific fontsize to heading row
4) how to apply specific fontstyle to heading row
With DataGridView1.ColumnHeadersDefaultCellStyle
.Alignment = DataGridViewContentAlignment.MiddleCenter
.BackColor = Color.CornflowerBlue

How to add a Check Box in the header of a check box column? I need to add a check box in the header.
View 3 RepliesI am creating a DataGridView in code, not dropping the object on a form in the visual environment, and the row header is ugly. I have been playing around with this for a while. I would like the row header to look "normal", and it does not. The row header is slightly larger than the column headers, and the border is not showing. I also am not seeing the "*" or arrow(pencil) for current row selected.

I created a DataGrid by dropping a DataSource on my Form. When I run it in debug, it works great.
My question is:
When I click on a column to sort by, ascending or descending, how can I tell which column was clicked on, and whether it is ascending or descending?
how we can sort a listview by a column without click event?
View 1 RepliesI have a DataGridView where I would like drawing custom glyph (let's suppose a triangle) on the column header when the user click on it.
I have the property EnableHeadersVisualStyles set to False.
how to reach the desired result? Do I need to inherit from DataGridView, or DataGridViewColumn?
Now the datagridView Header Background color is showing in Gray. I want to change to differenct
color.
I Changed the background color in ColumnHeaderDefaultCellStyle, but nothing changed.
How to do this.
Can I show checkboxes to the column headers in datagridview for each column in my dgv I Used [url] for help but it replaces the header cells one by one .Can I use any property of dgv which shows checkboxes for all column headers
View 3 RepliesI have a windows application with many forms. We use the DataGridView control on most of the forms, but on a new form that I designed I have four DataGridViews. All of the DataGridViews on this form do not dipaly the Column Header Text when the form is displayed when running in the IDE. I do not receive any errors or messages. The other DataGridVeiws on other forms display their column header text just fine. I am at a loss as to why this is happining on this form.
UPDATE: If I add the desired text to the column.HeaderText property at the end of the form load event it displays the column header text. For example AssignedAmountColumn.HeaderText = "Amount" it displays Amount in the column when run from the IDE.... However it dosn't display when the property is set though the Columns property at design time.
I have a datagrid and have added in some row headers:

However the row header width is very small and you cant read the header without adjusting it. What is the formatting command to automatically size the header to fit the text?
