DatagridView Column Selection
Jun 21, 2010
Am using vb.net 08 and i have a datagridview with 3 columns. The first column has a button as the columntype with the name "UserName". Now, i want if the user clicks only on the UserName which is the first column, but not the entire row, it should display the value of the UserName column only. If other columns are clicked are apart from the UserName, nothing should display. So there will be a for loop that will itera te through all the rows of the datagridview.
So i have something like this:

I have been looking all over the place trying to figure out how I can programally select a certain Cell in a row. What I am attempting to do is when doing Rowvalidating, and I find that the user has not filled out a column, I do a msgbox, then want to have the cell have the focus, so user can enter in the data. IE, like the way you can cause a text box to have the focus.

So I have a datagridview being populated with data from a database.At this point a user may or may not selected (via mouse click / key press) one or more rows within the datagridview.I need to (upon selection) create a new dataset, datatable and add rows with the some data from the said datagridview.
For example, if a table had nothing but names, e.g.
Joe
Sean
Larry
Chris
Upon the user clicking, dragging a selection over Sean and Larry to add those names to a new dataset so I can pass it to another method for further processing.
[Code]...
Input array is longer than the number of columns in this table.It looks like I'm either missing a column declaration or adding the table to the set?

I have a DGV I am working on, and I have many columns.
For example I have Columns colcase(Combobox), colreportTime(Time)
the combox shows 4 cases {A,B,C,D}
what I need to do is if the user select "C"
the the colreporttime will show the time of this change unless the old value is C

It 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 am using VB 2008. My DataGridView could contain a thousand rows in alphabetic order and I want my users to be able to find a row quickly without them having to scan through many rows. I could provide a row of buttons captioned A to Z or I could provide a search field in a textBox but in either case my program would have to find a particular row and focus on that row. Question one: Does DataGridView have a function that searches for a a particular value in a specified column? I have found no alternative to sequentially searching through the list. Question two: Once I have identified the index to a particular row, how can I make that row become the selected row?
There is so much to DataGridView that somebody should write a book specially about DataGridView. I would buy it.

I have a vb net program that shows a datagridview which pulls data from a mySQL database. When the user clicks on a row (I am checking for a 'cellclick' event), a text box is filled with data from a hidden column in the datagridview. This works fine and runs without error, BUT...When I use the cursor keys to move the selection up or down, the row highlight changes, but doesn't update the text box. I realise that this is because I am looking for a 'cellclick' event, but I don't know how to look for cursor keys as well.
Please could someone tell me what event I should be looking for to capture input via both mouse click and cursor. I have changed the program so it updates the second dgv on 'selectionchanged' but this crashes at run time with an InvalidCastException.Alternatively, is it possible to stop the user using the cursor keys?

I have a DGV that has a check box in the first column to indicate marked rows. After the user marks the rows they want then the OK button is pressed and the form closes. I need the row data that they marked to be transferred some sort of temp db (preferably in memory - 30 rows or less) so I can insert the data to a tabbed UserControl. I also would like to retain that row data while they are working so in case they want to open the form with the DGV again that the previous marked rows show up.

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

I have an inconsistency in behaviour when I try to get the CurrentRow after a row has been selected.
If I select the first row in a DataGridView object using the mouse, the DataGridView1.SelectionChanged event fires, and DataGridView1.CurrentRow is the newly selected row (Row 0).
If I select the first row via code however ie. DataGridView1.CurrentCell = DataGridView.Rows(0).Cells(0) then the DataGridView1.SelectionChanged also fires, but CurrentRow is the old row, not the new row.
In fact CurrentRow doesn't get updated until AFTER the SelectionChanged event has fired if you force the row change in the code, but is updated BEFORE SelectionChanged if you do the row change via the mouse or keyboard.
how to check if its the first row if I've moved to the first row using CurrentCell ?
