I have a DataGridView and one column has DataGridViewCheckBoxColumn type .The datagrid loads from selected items of a listbox.I need to hide Check box cell in this grid according to the item. It means some items should not have checkbox in that cell(I have the list of those items which should not have checkbox in that cell).
View 3 Repliesif there is a property of datagridview that will automatically formats the value of each cell but it will go back into original value before the user edits its data. This is only applicable for double datatype.
example. the value of the cell is 12908.21232311. But the datagrid will show only 12908.2123. And when the user edits the cell, the 12908.2123 will go back to its original form 12908.21232311. And when the user changed the value of 12908.21232311 into 12908.44444444, it will format again into 4 decimal places which is 12908.4444
I would like to make a applcation that after checkbox inside datagridview is checked. After calcuation stuff, if result less than standard, then it set the checkbox to not checked state. But I find that checkbox in datagridview does not change. It changed after I click other checkbox. What I want is lagging one cycle. I tried dgv.refresh() or update event , no effect.

I have been programming for alot of time. Generally i program in some languages like PHP, ASP.net, Java, JavaScript and others. In all languages i have to use alot of if else statments . Like if value= 10 then ... if i review my code then i find alot of if conditions. So i would like to minimise them but how not sure. one point was using classes somewhat minimised but still they are more... like task, cat, sec and type:

I was so happy when I discovered IsLittleEndian field in BitConverter. I thought of course it should be there and I should be able to specify whatever endian I like. Well, my happiness didn't last long. Spent some time till found out that there is no way to set the field.The field is readonly, and it is only set to true in static constructor:

My question is: how come there is very useful piece of code that is already implemented and sitting there in the FCL, but there is no way to use it (unless you start messing with reflection of course)? Is it just because some developers didn't meet the deadline and left the job half-done? Even if so, why the code is not available, but the field is?I hope there is a good reason for this.
I want to make myself clear. I don't need a solution on how to handle big-endian values. I do have a solution. The solution is actually shown in my question.
This LINQ to SQL query From g In Db.Context.Current.Groups Select g.GroupID
generates this SQL:

I very much want to select only the fields I need. How can I persuade LINQ to SQL not to select all columns?
I can't remember very well the instances where my selected items has disappeared as if I did a "Reset ToolBox", the last time I remember was when I installed the Service Pack early this year. But last year I think it has been reset frequently and I find it bothersome to reselect all those items again and again.Is there any configuration that I could set so that my selected items are safeguarded, that is they won't be removed no matter what?

Im trying to to detect what is in the string and so something for each different result but im not sure howto, here was my first idea but it obviously doesnt work as you cant use contains that way:
Select Case omg.Contains
Case "1"
MsgBox("1")
Case "2"
MsgBox("2")
End Select
I am working with cases, I'm only learning it so far, but just can't get a drop down menu to work that would change the background of a Textbox.
Private Sub cbColours_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbColours.SelectedIndexChanged
Select Case colours
Case Is = "Red"
txtSpace.BackColor = Color.Red
[Code] .....
It isn't doing anything at all...
In the dropdown menu, it has
Red, Blue and Green one per line
When the value (e.g. Green) is clicked, it will then change the Textbox to the colour selected.
Formatting the input text to upper and lower cases e.g Start with a capital.

View 10 RepliesWhat purpose do protected or private (non-static) events in .NET really serve?It seems like any private or protected event is more easily handled via a virtual method. I can (somewhat) see the need for this in static events, but not for normal events. Have you had a use case before that clearly demonstrates a need or advantage for a non-static protected or private event?
View 5 RepliesI am attempting to copy the value of the TimeStamp in cell A6 which has the NOW() formula into cell A5 Based on a change in Cell A4. The catch is I don't want it to update every time the sheet is recalculated due to updating links in other cells on the sheet. ONLY when Cell A4 Changes. What do I do?
View 2 RepliesI'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?

View 2 RepliesThe problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?
