Jul 8, 2010I'm loading a table from a MySQL-server, which loads fine, but I also get the following error:
Error 5: Index was out of range, Must be non-negatives and less then the size of the collection.
Parameter name: index
This is how I load the database:

VS 2010 Datagridview - Bound To A Local Databse Table Through A Linq To SQL Class - Adding Does Not Work
Sep 5, 2010I have a datagridview which is bound to a local databse table through a Linq to SQL class.
Everything works as I would expect, when the application runs, up to a point.
If, in the datagridview tasks pane I enable Adding, Editing and Deleting all work as expected.
If I disable Adding & Deleting, leaving Editing enabled, Editing works as expected.
If I disable Deleting & Editing, but leave Adding enabled, Adding does not work, despite the row for new records being displayed. I can move around the row but not enter data.
I suspect somehow its the datasource as opposed to the datagridview that is the cause of my problem but as I say, I can add rows if the Enable Editing option is selected.
Changing the relevant properties programatically makes no difference.
I've been searching for the reason for a couple of days without success.
I have a workaround, by leaving Enable Editing set and programatically setting each row during the RowPostPaint event to be readonly except the row for new records. I would just like to understand what is going on.
XML In A Dataset Without Significant Work?
Feb 15, 2010Question:Using VB.NET/C#, is it really not possible to read the below XML in a dataset without significant work ? I tried
oDataSet.ReadXml(strFileName)<BR>and
Dim oDataSet As System.Data.DataSet = New System.Data.DataSet
Dim strLocation As String = Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
strLocation += System.IO.Path.DirectorySeparatorChar + "filename.xml"
oDataSet.ReadXml(strLocation)
But all this is doing is putting ONE row with one cell with content "2010-02-12T10:33:39" in my dataset.

Sep 13, 2009I have a datagridview to show the database data in order to let the user view the data. But i am thinking of adding a checkbox column to the datagridview and when the user selects on the checkbox in the datagridview on a particular row, he can actually delete that row when he checks the msgbox are you sure you want to delete this?
I am also not sure on how to provide the provision for user updating through the datagridview. If he can update through the datagrid view and press the save button, and the database is updated, it would be better.
Currently i wrote the code for the inserting of data already . But i am stuck at the deleting and updating of data through datagrid view. the below is my code for inserting of data

.net - DataGridView Sort Does Not Work
Nov 9, 2010Visual Studio 2010 VB.NET
I have a DataGridView.DataSource set to a Collection of custom objects. The columns use read only properties from the custom object for display, this dialog is for display only. The properties all return String objects. I set the columns all but 2 of them to sortmode automatic (the ones that are not set is a button or a checkbox). Yet it does not sort. I have googled around and most people use sql or binding sources but I am using a trivial vb collection. Some say I should implement IComparable but isn't String already IComparable?
Per a request here are some code snippets.
This method defines the columns in detail from columns I designed in the designer.
The column names are called pSelected or pCustomer and corresponds with a property by the same name that the column definition ties to.

Datagridview Alignment Does Not Work?
Apr 22, 2010I'm trying to align datagridview columns at once to middlecenter. It works for the first column and does not for the others. I suspect it's a matter of the datasource property which is bind to a datatable which catches data from a SQL Server table. Below is my simple code and I thought that after this code runs I would have every column aligned to middlecenter:

.net - Going From Excel To A DataSet Or DataGridView
Jul 28, 2010I have data that I'm taking from an Excel sheet with the ultimate goal of displaying in a DataGridView.
Currently I am just going over the UsedRange of excel data and plugging it into a datagridview. This works fine, but can get bogged down when there 100+ rows of data.
I have also toyed with going from excel into a dataset (using the same wasteful method), and as expected it takes about the same time to load the data. Maybe use the XML from the Excel file?
EDIT:
Some Additional Information:
This is a WinForms application and the user will be picking and loading the excel file at run-time.
EDIT
The Return of Some Additional Information:
The Excel file is located on the user's pc. The general assumption is that they will be loading different files each time they use the application. [not sure if this helps, but might be good to know :)]
Datagridview That Is Bound To A Dataset?
Apr 9, 2012Okay so I have a datagridview that is bound to a dataset. I have a column called type is a string char of either C, R, A, or V. The problem is that I want to sort the datagridview rows using that column and do so in the order I just gave so I want rows with C on top and then R and then A and then V. Because these aren't alphabetical, how could I sort the items this way? I did look into the icomparer, but really wasn't able to figure out how that works.

Jan 13, 2012my question is, is there a way to filter records in the dataset and use that records to fill in the datagridview? for example, a datatable (with 3 columns: ID, StudentName, Gender) is filled with list of students. i have two datagrids in the form namely DatagridView1 and Datagridview2. DatagridView1 is where the the list of student where Gender is equal to M and DatagridView2 is where the the list of student where Gender is equal to F.in my current solution, i am using a loop.

Dataset And Datagridview Not Synchronized?
Apr 22, 2010I have a data bound datagridview where I am allowed to add and delete rows.So a new row is the last row in the grid with the '*'. When a user starts to type in the new row, that row no longer is considered the new row. It is then inserted into a row above the new row (*). The user, however, can press 'Esc' key and this row gets deleted.If the user does not pressed 'Esc' but move the cursor along that row, this row will be permanently there. I have tested this scenario and check the underlying dataset and it registers no changes as in the myDataset.hasChanges=FALSE.If I call myDataAdapter.Update(myDataSet), nothing gets updated. How do I save this row to the database?

IndexOutOfRange From Datagridview When Refreshing Dataset?
Oct 6, 2010I have a datagridview on a form that is bound to a table in a dataset from another class.I use a data adapter to .Fill a table in that dataset and the grid displays the data fine.Works fine.On my form I have a textbox the user can type in that will will pass a parameter to the storedprocedure used to fill this table. So on startup the textbox will have "%" in it. and then the user can type in "F%" and get everything that starts with an "F"
So when that textbox changes I launch an async refresh (.BeginInvoke) to do my refresh. The table gets populated with the reduced number of records (I check ds.table(0).rows.count and it is correct)
But the datagridview then starts throwing datagridview.dataerror events. "System.IndexOutofRangeException : Index # does not have a value".It looks like the dataset is getting filled correctly and not having any issues, but the datagrid is not liking this update. The index out of range error is so common that I'm not finding what I need through searches.

DataGridView - Create New Row And Update DataSet?
Jun 10, 2009I have a datagridview that was bound using the wizard and all the column created that way. So I haven't done any code to bind the datagridview. It will pull the data from the database and dataset just fine. My problem is when I create a new row it won't update the dataset or database. I have tried different ways that I thought it would work in the code and still haven't found a usable way to do it yet. Or if I need to do all my binding and columns through code give me an idea where to start if I have to go that route. This is my first experiences with Datagridview. I normally use comboboxes and textboxes to write to a dataset and database which all work very well.

I need to know how to display the First and Last name (both are seperate columns in the table).
