Hide DataGridView Buttons Only For Certain Cells And Show The DataTable Column Value Instead?
Oct 27, 2011I searched for this topic and all the examples are in C# (and they have errors as they will not convert with a C# to VB converter). I am using VB.net 2005 and would like a sample that work for it. I have a loop that goes thru the DataGridView and changes the row color based on a column/cell value from the binded DataTable (shown below). I'd like to add to the loop (where the comment is) and also hide the button for this cell and let the "In Process" show in the cell instead.
Private Sub ColorInProcessItems()
' Color the rows green if they are In Process, red if they are Complete

Show Bit Column As A Checkbox Column In Unbound Datagridview
May 14, 2010Dim 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

Show And Hide Data Based Off Of A Value In A Column?
Feb 16, 2009I would like to know how I can show and hide data based off of a value in a column.
Example. My table has 3 columns Name, Password, and Tel#
:Pseudo Code
if Name or Column(0).Row(0) = "Shawn" then
. Column(1).Row(0).Forecolor = System.Highlight
. Column(2).Row(0).Forecolor = System.Highlight
[Code].....
I placed my code in the rowprepaint event of the datagridview and on start up I get the results I am looking for. However, if the user selects the row or a cell in the row then the value will display.
I don't want the value to show even if the row is selected.
VS 2010 DataGridView - Null Reference On Setting Column Width?
Jun 9, 2010I have a databound DataGridView, and I'd like to keep one column in front, with a slightly smaller width than the default. The grid's AutoSizeColumnsMode property is set to Fill so that the columns fill out the entire grid. This makes the first column equally large as all others, which is why I need to set its width manually. The smaller column is the first one with the checkboxes. I have two grids that I need to do this with, and for some reason it works just fine with the first grid, but gives a null reference error on the second grid...
Here's the code for the first grid (working fine):
vb.net
Public Sub UpdateTodoGrid()
' Load todo items
todoGrid.DataSource = _TodoManager.LoadAll()
' Set backcolor
For Each row As DataGridViewRow In todoGrid.Rows
[Code] .....
As you can see, the code is exactly the same (except for not setting the BackColor of each row and not using the ReadOnly property*). When I run this code, it gives me a null reference error ("Object reference not set to an instance of an object.") on the line where I set the column's Width. Obviously 'col' is not Nothing (otherwise it would have errored before that line), and there's nothing else there that could be Nothing... I assume that something happens internally in the grid when you set the width of a column, and that there is a null reference there, but obviously I have no control over that.
The grid's are absolutely the same, as the second grid is just a 'copy' (meaning I copy/pasted it in the designer) of the first. So all their properties are equal. I thought maybe the ReadOnly properties were the problem, but I tried putting them in in the same way and the issue did not go away... The first grid is not ReadOnly (because the checkboxes need to be editable), but all rows except the first are, while the second grid is completely ReadOnly.
Print DataGridView (Text Wrap Top Header Column And Lock In Width)

View 4 RepliesDB/Reporting :: DataGridView - Datasource Does Not Show New Column
Oct 27, 2008I had a DataGridView that was bound to a Table in my typed DataSet. I recentyl added a new column to the table in the database and updated the table in the DataSet accordingly.Now, when I go to the DataGridView to update it, the new column does not appear under the "Databound column" list. I tried setting the data source to "None", then reselecting it. Still, it does not show the new column. I then deleted the DataGridView and re-added it to the form. Again, same result. However, when I select the data source, then click "Preview Data", it show the added column.

View 4 RepliesDataGridView Multiple Column Sorting
Jun 9, 2009I'm trying to sort multple colums in the DataGridView which is unbound. I would prefer to sort by using a DataTable/DataView but for some reason another developer in my team experienced other problems relating to sorting so he abandoned using the DataTable to fill the grid :(
Here is the senario: I want the user to be able to choose which columns they want sort on. The way I envisaged was to show a form with a listbox, a grid and 3 buttons (Add to sort, Remove from sort and Apply Sort).
The list box would be populated from the parent form grid column headings.
The grid will show the columns and sort direction.
Button 1 would add the selected item of the list box to the grid.
Button 2 would remove from the grid the selected row.
Button 3 would Apply the Sort in the order of the grid and the columns SortDirection.
Now I looked at How to: Customize Sorting in the Windows Forms DataGridView Control using the IComparer [URL]
how I can use the IComparer to sort on multiple columns that a user has specified or another way to sort on multiple columns using unbound data.

Aug 10, 2009I need to redraw a button in a button column in a DataGridView. Nothing to complicated other than I do not want the width to be as wide as the column width.

View 12 RepliesDatagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?
Feb 13, 2012It 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?
