Highlight In Datagrid The Subjects That Has Conflicts To Other Rows?
Feb 15, 2012
I wanted to identify the conflicted schedule of each of the section. If there's conflict then the two or more subjects that are conflict will be colored to make then noticeable. They are in datagridview. I don't know what's wrong but there are some that although they are conflict they are not highlighted. Here's my code:
For item As Integer = 0 To DataGridClass.RowCount - 1
For item2 As Integer = 0 To DataGridClass.RowCount - 1
If DataGridClass.Rows(item).Cells(ClassID).Value <> DataGridClass.Rows(item2).Cells(ClassID).Value And

I want to change the row color of every row in my DataGridView where a particular column value = "RBF3". I am currently using the DataBindingComplete event which seems to work fine, but it fires every time I change a cells value. I'd like for this bit of code to only fire when the datagridview is first displayed, sorted, or filtered. Is this possible?

I have a ListView that I populate with running processes and would like to highlight specific rows based on the amount of memory consumption. After I add the processes to the list and and call the WorkingSet64 property of the process, I tried this:
vb.net For Each lvi In ListViewProcess.Items If proc.WorkingSet64 >= 2000 Then lvi.BackColor = Color.Yellow End If Next
Processes is the variable I used to grab the collection of processes. proc is defined as a variable and then used to loop through the processes.
lvi is of course the ListViewItems in the ListView.So, by the code I have above, I loop through the ListViewItems, and if any of the processes are above or equal to 2000, then I set the background color to Yellow.
However, it sets every line to yellow, and I can't seem to figure out to set only those processes that have a WorkingSet64 above 2000.
Would I need to loop through the processes and then set the background color of the ListViewItem based on that? That kind of makes sense to me, but if I do that, I'm not sure how to set it just for those processes. Maybe by setting a separate variable?

This is going out to the forum at large. Where can I find the most complete explanation of the use of the DataGridView control in VB.Net? Any publication, or on-line reference except MSDN, please. I can never make heads or tales of MSDN.
Likewise, a complete tutorial on the usage of XML within the .Net Framework would be appreciated. Same qualifications as above.

Our site is developing against a 3rd party API (Wonderware) that returns datasets and datatables from certain calls. The issue we are having with some of the calls is the data returned is more than we want to show to the end users. We are binding the data to a datagrid, and will sometimes get back 20+ columns of data we don't need to show. Is there a way to filter the datatable of columns before binding it to the datagrid? Right now we are using the datagrid to hide the columns, but I think it would be better to strip out the columns of data we don't need before binding to the grid.

For Each row As DataRow In dgrFarms.Rows
Dim sendtroopid As Integer
sendtroopid = row("idColumn")
'Do Something
Next
I've been trying to get a loop through a row in just one column in VB.NET for a while now, and i've done my homework on it too. When i use that code above I get:
Unable to cast object of type 'System.Windows.Forms.DataGridViewRow' to type 'System.Data.DataRow'.
I saw another guide which told me to do:
For Each row As DataGridView In dgrFarms.Rows
sendtroopid = row("idColumn")
'Do Something
Next
But that gives me the error:
Overload resolution failed because no accessible 'Item' accepts this number of arguments.
(That's a blue underline on 'Row("idColumn") )

numbering rows in datagrid. I have a column that should number 1,2,3 so on when adding a new row. When I delete a row, those numbers should re-number still to 1,2,3. So when I delete row 2, the row that's been added as 3 should now number to 2. Then when I add new rows, these should re-number again, and so on..
My code:
'when adding a new row
Private Sub btnadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnadd.Click

I am new to vb.net as well as programming. (Windows application) I have only one data grid, one submit button on form. Datagrid has three columns name, age, salary
User will enter data directly in a row of datagrid. After clicking on save button data will get displayed in grid as well as stored in database.
User also can update data in any row, just by changing cell data of selected row and clicking on save button.
How I can update data in datagrid just by above way? How to guess which row data has changed? If user changes data in multiple rows, how to update multiple rows in this scenario? Can I have to take one extra column in database?

I bring data in from an access database using a sql query and then assign the data to a datagrid view. When i try to delete data from the table, it is removed from the datagrid, but the change is not showing up in the actual table.As a second question, is there a way to tag the specific row and send that back to the actual database for deletion? The way i have it set now, i think would delete all instances where digit, day, and office match, instead of just the selected record.

I have the following code in which it supposed to remove rows that have the first column checkboxes checked, but it only removes one row at a time.If you have more than one checkbox checked, you have to click the command button each time to remove the row.It seems that the logic is correct to remove multiple rows if more than one checkbox is checked, but it doesn't work.
