Datagridview On Datarepeater Showing Only Most Recent Fill
Jun 14, 2010
Is there any way to have a datagridview on a datarepeater with more than 1 row showing?
I have a datagridview on a datarepeater control. The datarepeater and the datagridview are joined on a common field in 1-to-many fashion. The form is designed so that there are 2 rows of the datarepeater visible at any one time. The datagridview is populated in the datarepeater's drawitem event The problem is that it behaves as if there is only one datagridview total rather than one datagridview per row. The drawitem event executes when you scroll to a row. Because 2 rows of the datarepeater are visible, the fill code is executed twice when the form is opened. But the second fill overrides the first one. So you've got this form with 2 different rows but the data in both datagridviews is the same but is right only for the bottom one.
Is there any way to correct this? If I made only 1 row visible, that would eliminate the wrong data. But I want to be able to show more that 1 row at a time.

So there's lots of examples of how to do this if your text file happens to be in XML format. However, my text file is not in XML format and as it contains over 172,000 rows I'm not that keen on adapting it (it's a dictionary)! The text file has been included in the project as a resource.
So far I've got a DataGridView (could use a DataRepeater if easier?), a BindingSource and a DataSet.
The DataSet has a DataTable already defined in the designer with one column.I've managed to load the text file into a String and then create a StringReader based on that String variable, however I cannot find anyway of loading those strings into the DataTable.
Dim listWords As String = My.Resources.WordList Dim strReader As New System.IO.StringReader(listWords)
'What now???There are some examples of using OleDb functionality but all assume you're loading from a text file residing somewhere in the filesystem, not a project resource.(I'm also assuming that on building the application the resources get embedded (somewhere) rather than being accessed from [AppDir]/Resources/[filename] ??)

I just want to display data of a single column from an oracle table into a datagridview or a listbox for readonly with no requirements to make changes to it. Simply display the information.What is the best way forward... To used DATAADAPTER or DATAREADER.s DATAGRIDVIEW SLOWER TO FILL THAN a LISTBOX.i am using the following code to fill datatgridview but for some odd reasons at time it is slow to display the data. I want to use listbox instead

I am trying to fill my DataGridView using a date for my parameter. My first problem was in my code where I would get the common error message of Too many arguments to public overrides overloadable. I solved that error message by going into the dataset designer, selecting the query and adding RegDate as a parameter. Now my problem is that I will enter a date in my tool strip text box click the button and still get my data grid view filled with all the data.
Try
Dim RegDate As Date = CDate(RegDateToolStripTextBox.Text)
Me.PatientsTableAdapter.FillByDate(Me.Database1DataSet.Patients, RegDate)

I have looked around quite a bit, and nothing seems to answer my question in particular. I have DataGridView in which I add rows and columns dependent on a certain record count of geospatial data that is held in ArcGIS. The data is then passed through to the gridview for editing. So I do not use any databinding methods, rather it is a very manual process. I store data into a two-dimensional arrays, which indexes are based off of those certain data record counts. After the loops are complete, the data should be stored in each cell dependent on index. The very last row that was populated is populated perfectly, yet the other 72 (or so) rows are blank. Here is the code as follows:

Have a unbound Datagridview with first column set as a checkbox and second column just has text.When adding a row the checkbox does not show, what am I doing wrong.Code to add Row:
DataGridView2.Rows.Add(False, FolderBrowserDialog1.SelectedPath)
The code that adds the rows also saves to a file and then there is seperate code to load datagridview at the start of the programme.If I close and reopen programme it displays the checkboxes.

With this project, I created a SQL Server DB with related Dataset and DataTable a while ago with about 10 columnsWith the code below, I fill those columns with values in a new row and add to the datatableThe datatable is bound in a datagridview and all has worked fine until I tried to add a new column to the dataset/table. After adding the new column and rebinding the datagridview to the updated table, the DGV now shows the new column, but the data for that column fails to show up in the DGV.
Dim dt As Date = DateAndTime.Now
If My.Forms.DataGenerator.TextBox4.Text <> "" Then
My.Forms.DataGenerator.TextBox8.Text = dt

For a class project I'm supposed to write a program that requests a team as input and displays the players from that team in the first column. The players should be sorted alphabetically by their last name, and if they have the same name they should be sorted by first name accordingly. My program compiles and I'm fairly certain that I've done most of it correctly. The second column should be filled with the batting average of the corresponding player from the left column.
My problems are as follows:
1) I can't get the DGV output to show correctly, it posts the player's name with the batting average of that player in the following downward cell.
2) I'm not sure how to further use the .Split method to separate the first and last name after already separating the name from team/at bats/hits, and can't find any info regarding this topic. Also, I can't figure out how to sort in reverse, I've only seen the Ascending and Descending options so far for sorting.
3) Is the way I've figured the batting average the most efficient/correct way, or is there another better way?

I am using VB 2010 with an Access 2010 database. The Access table is the data source for a DataGridView created by dragging the table from the DataSet onto the form. The table has 3 columns - First, Last and DOB (Date of Birth). I want to have a column in each row to show the person's age. I added an unbound cell in the DataGridView called Age, but cannot figure out how to fill the cell with the information I need. I tried using the DataName property, but that will only allow me to enter columns already in the grid. I think what I need to do is fill this cell (Age) by a value computed from DateDiff(DateInterval.Year, DOB, Now), but I cannot figure out how to do so.

I have a database with values as shown in the attached image "Image1.jpg". There are multiple other columns not shown on the screenshot (over 30), for the sake of this question we'll say I'm interested in columns called "Col1", "Col2", "Col3" & "Col4".
I was able to get this information automatically filled into a TreeView as shown on attached image "Image2.jpg".
At this point I also want to fill a DataGridView from the same database.
I managed to accomplish this with the following
Private Sub FillDataGrid()
Dim DA As New OleDbDataAdapter
Dim DS As New DataSet
[Code]....
But unfortunately this uses the manual binding of data to the DataGridView, which I'm sorry to say I struggled to "convert" if you like, to using SQL commands and coding to connect a database to DataGridView.

I am totally new to VB and ADO. I know that we can bind a data source to the datagrid view but if I want to populate the same datagrid view with different set of data but the column names are the same. Based on a date range entered by the user I would like to populate the datagrid view. Can we do this at design time? If I not how do I do this?

I have a datagridview with 3 columns.
Now I need to fill the datagridview's datasource with 3 arrays.
Example:
(column1) Username- Joe - Mark - Thomas
(column2) Password - Joe - Mark - Thomas
(column3) Activiated - Yes - No - Yes
Then after i split what should I do? Should I add 3 arraylists in a class or should I use structure and how?

I'm looking to display some data taken from an Access database. It's just a table of data but all of Visual Basic DataGrid stuff seems too...bland and businessy. I want something that looks really attractive and would be suitable for a game (a sports management one). I'm using some Krypton Controls and even though there is a DataGridView in there, again it's not what I'm looking for. I could just have a listbox for each column of data and that would allow me to customize the style completely, but it would be a bit fiddly working out sorting and stuff (even though I reckon I could do).
