DGV Not Updating Fast Enough (Index Out Of Range)
Jan 16, 2010
I have this:
vb.net
Private Sub doWork_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles doWork.Tick
Me.doWork.Stop()
For outer As Integer = 0 To Me.queriedDGV.Rows.Count - 1
For inner As Integer = 0 To Me.hebdataDGV.Rows.Count - 1
Application.DoEvents()
[Code] .....
It works fine when I step through it with F8, but when running normally, I guess it's going so fast that I get an Index out of range when the outer For loop increments to the second iteration. I tried putting a timer in there to give it a chance to update the UI, but that didn't work. I also tried "Application.DoEvents" as a last resort, and that didn't work either.

I have a datagridview, with 3 columns, each containing dropdown filters (in the column header). Of the 3 columns, 2 are working perfectly fine, but whenever I try to filter the 3rd column, it gives me this error: (Also all of the column's have the ColumnType property set to: DataGridViewAutoFilterTextBoxColumn) "Index was out of range. Must be non-negative and less than size of the collection. Parameter name: index." The error points to the part that begins with "If dgv1.Rows(e.RowIndex)..."

Trying to input a high setpoint, low setpoint, a % load, and number of compressors, then calculate the temp that all compressors are off. Then build a datagridview with the staging of compressors from all off to all on for each compressor up to 10 compressors.I am trying to insert headers from 1 to 10 compressors (Variable) with the text "Comp1", "Comp2", etc....Two rows with header. I am trying to use an array with index number to insert the text, but that is where my problem happens."Index was out of range".Here is my code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer, num1, num2, num3, num4, alloff As Single, stg As Single

I am working in VB 2008 and I have set up a datagridview to display rows of data which can then be selected. When I select the first row I get the error: Index was out of range. Must be non-negative and less than the size of the collection. When I select any other row the program executes as it should. From what I have learned so far is that the DataGridView has an index of -1 and that it counts the header row as part of the index which is the -1.When I select the first row through either DataGridView1_RowHeaderMouseClick or DataGridView1_CellContentClick the index is 0 for the first record. If the index is 0 I think it would fire off, but I have no idea what is happening behind the scenes. I can check the index, so when it is 0 and the code attempts to access the row, that is when I get the message.On an index number of 1 and up the code executes fine.So, is there a way to re-index the DataGridView, or is there a work around/fix for this issue?

When you need to do random access to the lines of a text file, the regular solution is to put those lines in a list and access them in that list.But doing this if the text file is large creates a large memory overhead and may cause some memory stress on the application.This class maps the file and provide the ability to read any particular line in the file at a random position, without the need to read or put in memory any other line but the desired line. The only memory overhead involve is the 1024 bytes buffer of the base stream.Even if the file mapping can be a process that consume a noticable amount of time if the file is very large ( ~ 5 seconds for each 100,000,000 caracteres) , once the mapping is done the access to a particular line becomes instantaneous regardless of the size of the file. (The file mapping can always be done at a convenient time (ex when the process load) and can be done on a worker thread The class is base on a StreamReader to support the differents Text Encodings Example uf usage ( As I say, if the file is very large, dont do it like that, but declare the class at a convenient time)

I'm trying to grab the values that have changed using the GridView_RowUpdating event.
Here is my code:
Dim newValues As String = ""
Dim oldValues As String = ""
Dim i As Integer
Dim j As Integer
[Code] .....
Weird thing is, it seems to pull OldValues fine, but when I try to pull the NewValues I get an "Index was out of range." Checking around I see that this sometimes occur if you have non-BoundFields in your Gridview, but all of my fields are bound!

I was trying to add two quantities at different rows of same description i.e same product_name and same item_pack.1st I want to check the table if it contains the same description or not by comparing with the first record and so on. When found, I'll add up the quantities and then to delete that particular row (to avoid duplicate search). But when I delete the row the particular row, next time it throws an out of index exception
