i need to group the rows of a datagridview rows basing on values in column1 of DGV.i mean for example while loop
if .Rows(TOPROW).Cells(0).Value =
.Rows(NextRow).Cells(0).Value then
color the rows with some unique color
else
color them differently
I was looking for some code that would change the colors of some rows in my datagridview but I could not get that to work. I have this code which should work but it doesn't, I could not find any replacements. I need to change the color of some rows.
Do While cnt > -1 If datagridorder.Rows(cnt).Cells.Item("DataGridViewTextBoxColumn16").Value.ToString.Substring(datagridorder.Rows(cnt).Cells.Item("DataGridViewTextBoxColumn16").Value.ToString.Length - 5, 5) = "Cease" Then
datagridorder.Rows(cnt).DefaultCellStyle.BackColor = Color.Red
End If
cnt -= 1
Loop
I am trying to change the background color of specific rows in my DataGridView. Nothing is happening here.[code]
View 17 RepliesBasically,I would like to bind the data into datagridview which called PODetailsGrid during page_load. After the data had been bind into the gridview,I would like to make alternate color in each row. For example, the font color for row1 is Black,then second row should be Red,then third row will be Black again and so on..
Code: Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I am trying to summarize a datatable based on a primary column and then add certain columns. For example this table
col-1 col-2 col-3

This simply doesn't do anything becuase it thinks the target table doesn't have a primary key.
How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
View 2 RepliesI have populated a ListView with currently running processes and with the help of JMC, been able to highlight specific rows based on memory consumption. However, I've decided to change it up a little bit and change the color of rows based on whether the process is owned by the User, if it's a System process, or if is a Service. I've already been able to determine if the process is a User process by utilizing the OpenProcessToken.

I'm filling up a datagridview from a datatable which is populated by sql queries.

View 4 RepliesI am having trouble with multiple selected rows in a DGV. I have the following line to test how many rows have been selected.
Dim NoOfRoomsSelected As Integer = MonthDGV.SelectedRows.Count.ToString But each time the value comes back as 0.MSDN says : The SelectionMode property must be set to FullRowSelect or RowHeaderSelect for the SelectedRows property to be populated with selected rows.I have this set to RowHeaderSelect.
I'm doing a simple search of rows in a DataGridView. If the search finds a record matching the search criteria that row gets selected. I just added the BindingSource.Find method
If the row I'm searching for is currently showing in the DGV's viewable area, then my code will find the record, if it's not showing, meaning you have to scroll up or down to see the record, my search does not find the record.
(Correction: It finds the record but the DGV does not scroll to have the selected row be in the viewable area.)
Here's my
vb
Private Sub SearchForSite(ByVal site As String)
DeSelectAllDGVRows()
Me.Cursor = Cursors.WaitCursor

I have a DGV where I'm setting the backcolor of certain cells to light gray. But I need to be able to restore the backcolor to what it was before I changed it to gray. I could just set it to transparent, but the problem with that is that I use an alternating row color of alice blue for the DGV & setting a cell in a blue row to transparent makes it white. So, in summary, I need to be able to restore white rows to white & blue rows to blue. Any ideas? I thought about checking the backcolor of another column in the row & then using that to reset the cell, but that seems kind of a hack.

I am having trouble adding a row to a databound datagridview on a parent form from a child form. I have two forms, one contains a datagridview that is bound to a table using 'datagridviewbindingsource' and contains an 'add' button. The second contains a checked listbox that is populated correctly and has a "Cancel" and an 'OK' button - when i check several items in the child form, i would like to hit okay and update the bindingsource of the datagridview on the first form with the checked items.
Code:
in form1 when btnAdd is clicked
dim f2 as new form2
'call it as a dialog to check for the cancel button
f2.ShowDialog()

I have a datagridview and I'd like to write it to a file in the same type of row and column format it's currently in.My first idea for doing this is to get the maximum number of characters in each column so i know how wide each column has to be formatted. Then loop through each row and write out each row while using the max characters in each column and the current cells content length to do the math to get the formatted columns to line up. Like the example below, except i'd have a lot more in it.
writer.WriteLine("{0,0}{1," & lb(2).Length + 50 - lb(1).Length & "}", lb(1), lb(2))
This takes label(1) and label(2) and writes them so no mater the length of either (to an extent) then will always be right hand aligned in two columns.

Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.
