Jun 29, 2010
With .net 05 and datagridview
Error: Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index
I am just looping through a datagridview cells of some columns, my datagridview is having 134 rows and 09 columns, but my code stopping at row 124 stating above error.
My code is here:
Public Sub IScoLP(ByVal dGRid As DataGridView)
'SHUNTING
Dim w As String = "SHUNTING"
Dim T_wTYPE As Object
Dim T_ALp As Object
[Code] .....
How do you loop through a name column in a DataGridView? What is the collection? The following below does not work.For each X in DataGridView.Columns("Name")Next
I have a DataTable and want to connect the cells of one of its columns to cells in some other DataTables.
For example:
DataTable1.Rows(0).Item(2) is connected to DataTable2.Rows(4).Item(6) DataTable1.Rows(1).Item(2) is connected to DataTable4.Rows(2).Item(3) DataTable1.Rows(2).Item(2) is connected to DataTable3.Rows(11).Item(4) ...
How do I add the cell on my datagridview? I am not sure how to do that but I have four columns which I want to add the cell on 3rd column on my datagridview.
I created a DataGridView and entered some data in it,at runtime it looks like this:Attachment 72177Here the 3rd row name column cell is a bit short according to the name size....so i want to increase the cell size at runtime such that the user can see the full name.....Again the roll and age cells are a bit short.....so i want to decrease them as well..
I tried this with the AutoSizeColumnsMode and the AutoSizeRowssMode but in vain...How to do this?
I'm working with datagridview.I found an example on the web about creating a datagridview: firs I make my array containing data, then I make a datatable from array, then I make datagridview from datatable.I don't know if it's the correct way but it seems work.In a column I make random numbers for test: for example I have on column "Time" these values: 1155, 1725, 584, 996, 1352.Then I try to sort with code when I press pushbutton: it doesn't work because I have the values:1155, 1352, 1725, 1758 (until now it seems to work correctly), but then I have 584 and 996 values: wrong!Ok, let's try with the manual sorting: same result.I filled cells with "integer" values, let's try using strings, then I used "value.tostring" same result.I also tryed to fill strings with blankspaces to obtain same length, but nothing changed. "1155", "1352", "1725", "1758", " 584", " 996".Then I tryed to fill with "0" values:"1155", "1352", "1725", "1758", "0584", "0996".The same.How can I fill cells values?
am converting some excel macro to vb.net, and it's almost done, but when i am looping throught +- 3000 rows and checking with 2 sheets it takes about 3 hours !
Dim Site1 As String Dim Site2 As String Dim Group1 As String
I have a DatagridView with 12 columns. I would like to insert 3 Columns AFTER it has been filled with data from the table.The first New column should contain the total of Col1, Col2, Col3.The second new column should contain the total of the (old) Col4, Col5 , Col6...
I have a datagridview that is bound to a datatable. When the form is displayed, the column headers have no sort glyphs and the columns will not sort.
I don't see a property on the form that controls column sorting - at least not one that's obvious. This is an area of the code that another developer wrote originally, so maybe there's something going on that I'm not aware of.
I'm trying to allow users to resize columns of my datagridview, but it's not working. I have this line: DataGridView1.AllowUserToResizeColumns = True I want users to be able to resize columns the same way they would if in excel.
I have an unbound datagridview with a whole bunch of columns.I need to sort based on 4 columns, the first three are simple strings, the fouth is a date string (which in itself presents a problem, since it wants to sort lexically but I need them in date order).
All fields from my class objects are added to the columns collection of DataGridViews, when the forms or custom controls that contain them are viewed within the VS 2005 designer. I haven't been able to figure out how to stop the designer from auto-adding all of the fields found within the bindingsource object.
I have a datagridview that I'm populating from a SProc. The data coms back fine and is presenting in the DGV without any trouble, but I don't like the order the data is being returned in.A long solution might be to modify the SProc to return the data in a different order, but I prefer to handle this on the UI for simplicity. Also, I know the user can re-order but that presents a specific poblem in the way the columns are structured.Is there a way to programmatically change the order at runtime?Here's the ode I have on the UI. If you need to see the adapter class also, please let me know and I'll present it, too.
Code: Private Sub UpcomingInspections() AddHandler mAdapter.ErrorOccured, AddressOf HandleDataError
I have created a Windows Form Application with a DataGridView. I want a DateTimePicker in some of the cells (not in complete columns). I've managed to find a solution wich works nicely.
Public Class Form1 Private WithEvents dgv1 As DataGridView Private WithEvents dtpCell As DateTimePicker Private flp As FlowLayoutPanel
I am trying to write a module that will select cells from multiple, non-contiguous columns within a row that is defined by a variable. The column numbers are known and are unchanging. For example, my worksheet might look like this:
A B C D Row 1 X X X X
I want to select cells A1, B1, and D1; however, I don't want to use the row number (1 in this case) in my code. Rather, I want the row number to be specified as a variable. The code I am writing is inside a For/Next loop, so I would like to use the iterative variable (i in this case) to define the row number. That way, every iteration of the For loop will select cells from a different row.
Mine is a windows app. containing forms named BOM nd BOMSelected..There is datagridview in BOM which contains checkbox column.. When the user selects checkbox, the selected rows should be seen in the datagridview of other form, SelectedBom..I have coded but don't get it working.. Some error..
Here is what i have done !!
Public Class SelectedBom Private Sub SelectedBom_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'TODO: This line of code loads data into the 'HemDatabase1DataSet4.partno' table. You can move, or remove it, as needed. 'Me.PartnoTableAdapter.Fill(Me.HemDatabase1DataSet4.partno)

i would like to know the syntax for this.i wanna add the values of 2 cells and then i will display their total in textbox.i have been trying to use datagridview.rows.cells but i cant just use it to add to cells values.
i wanna compare my cells in datagridview. I have a datagridview with n columns and n rows. I have my datagridview row value as Time . I need to compare all the row cell values with one particular time.
Here you go with an example.
if my dgv is filled with time values such as 3:42:10 AM 4:43:17 PM etc..I need to compare all the cell values to 5:00:00 PM. greater than condition. I need to highlight only the values which are greater than 5:00:00 PM but less than 3:30:00 AM.
I'm current in college and working on some computing coursework and putting the finishing touches on it when i stumbled across a bit of a problem.I'm trying to compare two cells in a database and i use datagridview to display the database in my form. The database is created by sql commands within my actual program if that makes any difference. What i have created for my coursework is a program that manages the stock and such for a small music shop and in the stock table im trying to compare values in two different collumns, but in the same rows. I need it to display a message box in the event that the value in the one cell is less than the other, which is basically checking if the stock for a certain CD has fallen below the reorder level.
I'm trying to fill a DGV from a (List Of).. This is my code. It's not working & I don't know why..

I have a datagridview and I want to click on it BAD to jump to 4 cell, but to walkwith the arrows is normal, I did this because the KeyDown / UP does not work becausethe cells are in Edit Mode:

I'm completely newbie and I have been trying to solve a problem that is strongly related to what you guys had discussed here .
I have a datagridview (datagridview1) on my form and it is not linked to any database. I'm only trying to programatically enter values into the rows of the grid by values that my program generates.
For example if the value that my program generates is x, y, z then I would like to say something like[code]...
Is the following grid layout possible with DataGridView in VB.net? Kind of similar to html table layout. I'm adding data cell by cell. However I'm not sure on how to get the layout for Group A & Group B Cells. -------------------------------------------------| | Item11 | Item12 | Item13 | |-----------------------------------------| | Item21 | Item22 | Item23 | GroupA |-----------------------------------------| | Item31 | Item32 | Item33 | |-----------------------------------------| | Item41 | Item42 | Item43 | -------------------------------------------------| | Item51 | Item52 | Item53 | |-----------------------------------------| GroupB | Item61 | Item62 | Item63 | |-----------------------------------------| |Item71 | Item72 | Item73 | -------------------------------------------------|
