i use a linq query to pull data from an xml inventory and place it in a a DGV, problem is the column ordering appears to be in the same order as the properties and fields in the row object class and not the order extracted from the xml with LINQ. I suppose i could rearrange the class so that it refects the column ordering i need but i'm wondering is there a way i can control programatically the order of the columns for my DGV? and why does it use the class structure rather than the query structure anyway? the class is done alphabetically as i wrote it with class diagram and class details, the LINQ query is in the order i need it in.
View 9 RepliesI have a question. How can I perform a drag drop(without reordering) in a datagridview? I mean just moving two rows to each others places. Like this:
AAA
BBB
CCC
DDD
EEE

View 1 RepliesAdd persistence to multible DataGridView in terms of Hide/Show column and column width
View 1 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?

I have:
- Table1 with columns: PK_ID1, LOCATION, DIRECTOR, SELLER, SELLERID, WORKTIME (relationship), WORKCODE
- Table2 with columns: PK_ID2, WORKCODE (relationship) & WORK_DESCRIPTION
My DataGridView do a SELECT * FROM Table1;How can I replace WORKCODE with WORK_DESCRIPTION in DataGridView, please?
Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime
Is there a way to find the column index of a datagridview column using the columns DataPropertyName?I currently use a loop (shown below in the class) which is kind of ugly, but it works. I'd like to do something like this, which seems more elegant.My goal is this, I store the users DataGridView column settings (i.e. DisplayIndex, Visible, & Width).When the user opens the form that contains the datagridview I want to get those settings from the database and apply the settings to the datagridview.[code]
View 5 RepliesI have a data gridview on my windows form with 4 columns. Now I identify a column as followed:
Dim item1 as String = DataGridView1.Item(1, index).Value

View 17 RepliesI 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...

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

I have a datagridview (dgv) and if the user changes the size of a column or moves the column to the left or right, I want to be able to save those changes, so when the user sign's on again, the dgv will show as it was when the user closed out of it. Is there a way to do this?Also, is there a way to "freeze" columns? For example if I have 10 columns, I freeze column's 1 and 2 (to the left) so whenever the user scroll's over to the right, column's 1 and 2 will stay on the screen.
