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.

Highlight DataGridView Rows Based On A Columns Value?

Jan 27, 2012

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?

VS 2008 Highlight Rows In A ListView Based On Specific Conditions?

Oct 12, 2009

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?

The problem is when I search through a textbox and nothing matches the search query, I accidentally click the column header which is the lastname then the error "Object reference not set to an instance of an object." pops up.

The highlighted part of my code is the text closed in quotation marks.

btnDelete.Enabled = False

Searching And Displaying Specific Records In A DataGrid

I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.

Hide Rows In A Datagrid?

Oct 13, 2011

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.

Looping Through Rows In A Datagrid?

Mar 27, 2012

For Each row As DataRow In dgrFarms.Rows
Dim sendtroopid As Integer
sendtroopid = row("idColumn")
'Do Something

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

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") )

DataGrid - How To Update Multiple Rows

Feb 27, 2012

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?

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.
