I've been looking everywhere for an answer to a simple question, but i'm having issues, so i thought i'd join and post here. I'm having issues with a simple concept. I load information from a SQL database, and i want to add a 'Passport' link URL relating to column cells called 'name'. It basically selects the name, and inserts it into the link fields to be opened. But i cant find a way to work it. I thought i could do it with something like:

I am implementing a search form for a database, and I have the search functions working how I want them to. However, I have two connected tables, connected by an "ID" field. In the DataGridView that I use to show results, I want to have the functionality to be able to click on a certain row in the table, and the second table would update to show the data connected to the selected row.

how to copy a selected DataGridView cell to a textbox. Meaning when I double click a cell it's content is the =Textbox.text. Maybe something in the click event and datagrid selection. Don't know how though.

I want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.

NB: I'm using Visual Basic.NET?My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid.When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid.So, basically, I want to dynamically display data in one grid based on user selection in another grid.My code looks like this so far...
Private Sub RulesGrid_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles RulesGrid.CellClick
Try
FlagsGrid.Visible = True

I am trying to update a row or a single cell in ms access through vb.net. But when i update the text box named NRIC, say for example i want to update "s4522147B" to "tr4521856C" and mean while leaving the other fields the same.
But the thing is when i make the changes in nric.text (textbox), the dataset actually updates the whole column in the table instead of the selected textbox.
Below is my code for the update part

I have a datagridView,which is filled with the Click of the Button.My Issue is i can see the data only when i select a row.When no row is selected by mouse then its just showing blank cell,whereas data is actually there in the datagridView.I know its something with the color setting from the DatagridView Properties.I have tried and corrected all the cell Style properties related with that DatagridView.And set the Cell Style properties exactly the same as of my other datagridview,which is working fine.

I am trying to get back a single from from a EF database model using the below line of code..
Dim _classRoom As classrm = db.classrms.Select(Function(b) b.Course_ID = _CurrCourse.course_ref)
Where classrm is the name of the entity and db is declared as a new entity. What I am trying to do is select a row from the entity based on matching Course_ID which in this model is a string. So that I can later use the variable _classRoom to get other items out of the same row.. However I am getting the following error:
Unable to cast object of type 'System.Data.Objects.ObjectQuery`1[System.Boolean]' to type 'Trial_Online.classrm'.
I have to preform similar tasks with several different Entities but if I get pointed in the right direction I can manage from there...

I am working on a vb6 to vb.net migration project using vs 3.5. I have a datagridview.in a particular cell of this grid, user has to enter only numeric data. but after user enter data, itshould become concainated with a $ symbol (eg: if user enter 34, the cell value should become $34). And if he/she presses the hyphen ("-") in the key board, the data (ie. $34) should become -$34 and if again presses the hyphen button in key board, the data should become $34.

My code is this:
Me.Validate()

At first I can insert data into the cells and save it... but when I try to edit the same cell with data already saved in it I get this error...
sqlcelexception was unhandled
There was an error parsing the query.
[ Token line number = 2,Token line offset = 29,Token in error = , ]
I also get the same error when deleting an already saved cell with data.

I am updating my last post so hopefully someone will help. I have following code that will move a cell to the next column when hitting the enter key while doing an edit. It will even check the row at the last cell to validate data is present.
However, if there is no data in a cell and I press enter, the focus moves to the next line like it normally does. I need to prevent the user from moving or clicking on any cell until the cell they are on has data in it. Here is the coe I have used[code]...

I'm looking for a way to use two DateTimePicker controls to select a range of hours and minutes within one day. That is, to basically select a 'starting time' and 'ending time'.
I started with two DateTimePicker controls with the custom format of h:mm tt. I tried adding (on ValueChanged), a check that made the selected 'starting time' will become the 'ending times' minimum and vice versa, the 'ending time' becoming the 'starting times' maximum
However, that approach didn't seem to work -- I was still able to select 11.00 AM on the 'ending time' and 1.00 PM on the 'starting time'. I have a feeling that the current day of the timestamp has something to do with it (e.g. the starting time is of the previous day, and therefore is less).
I thought about changing to a combo box of preset half hour intervals throughout the day; however the minutes need to be more flexible than that...
UPDATE:
Dan's comment below answered this problem... This is the code I ended up with for reference;
Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged
