I want to disable column in datagridview so the column will not receive focus,
when user press tab to move from cell to cell this column will be skipped and the focus move to the next cell or column.
My problem is I have a data grid in Visual Basic, it works fine but as the columns extend past the width of the window I needed a scroll bar. This is where the problem arose. When a column past the 4th is clicked the scrollbar will shift to give it focus. As there are check boxes here they are constantly clicked and when they are the scroll bar shifts but the button isn't checked and must be clicked again. I was hoping there was a way to disable this Auto focus so clicking a column will not cause the scrollbar to move.

View 27 RepliesI have a DataGridView that based on certain conditions certain columns or rows or cells need to be locked/disabled but the data in the columns or rows or cells needs to bvisibleNow let me define what I mean by lock/disable; the user cannot click on any cell that islocked/disabled, if the use is using the arrow keys the selected cell cannot move to a locked/disabled cell.So this means that setting the cell as read only will not work, the user can still place the cursor on that cell.

Add 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.

How can I disable this column entirely, I mean even disable focus event (can't click, can't use Tab or arrow keys, etc.)
I 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?

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...

VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.
