I have a window based datagridview with examdate as one the editable datetime column .Now i want user to update or change the date to a fully valid format(dd:mm:yyyy) just on pressing enter key within the datagridview. A popup message must appear when user enter wrong date.
View 1 RepliesI am doing work on a new logging database that I have decided to use UTC datetime to store all datetime values since our company spans timezones and multiple sources and timezones are logging events.However the problem that I cannot get my head around is formatting the datetimes in my datagridview for my user application.Our applications use mostly LINQ to SQL to manipulate our data from generic SQL CRUD calls, so I am hoping I can mask/format the DGV to get the conversion or some LINQ function rather than having to write special SQL stored procedures to do it every time I need to display the data.. (I have found multiple sources that explain how to do that)
View 1 RepliesWith my datagridview I have column for datetime. I used the following for format.
Mydatagrid1.Columns(3).DefaultCellStyle.Format = "dd/MM/yyyy"
But the problem is it's getting input like MM/dd/yyyy and after pressing enter it's changing to dd/mm/yyyy style. So is it possible to read input like "dd/MM/yyyy".
I am trying to link two columns with dates and time to a new column, but the original columns are not in DateTime format. Here is sample of the data:
C_DATE C_TIME

211152

View 1 RepliesThe code below updates all cells in a DataGridView column to a value from a textbox. This code works in that all cells in the desired column are updated on screen. The DGC is bound to a dataset. The problem is that when I call the dataset .Update method, sometimes the first row (row 0) does not get updated. I have run SQL profiler and can see that no SQL update command is submitted for the first row. The first row only gets skipped the first time the update is run after launching the app. Subsequent updates run for all rows, until the app is re-launched.
I have verified the row state is Unchanged with: Msgbox(DataGridView1.Rows(r).State.ToString).
The 2 commented lines below are other things I have tried that still cause the first row to be skipped.

I've got a datatable with a DateTime field that I want to sort using a DataView. I only need the Time part of the column though, and not the date. I can't get it to show just the time and not the date as long as its a DateTime column. I know I could convert it to a string to get the time, but then it wont sort correctly.

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?

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.
