I've got a DataGridView that has a DataTable as the DataSource. If the user has rows selected in the DataGridView, calling AcceptChanges on the DataTable will clear the selection (highlight) from those rows. Can this be prevented?
View 6 RepliesI am modifying a couple of fields of a datarow and immediately calling AcceptChanges on this datarow. Technically, after calling AcceptChanges, the RowState of the datarow must be "Unchanged", but it is still "Modified". Why is this so?
View 3 RepliesI am having an issue with a DataRow not being updated in my DataTable. The trouble is my value is not being changed in the row.I have done a simple example which shows what I am trying to achieve. My row does not change values...ever...and no errors are found
Dim cm As New DataTable
cm.Columns.Add("Name")
cm.Rows.Add("Craig")
[code].....
if the rows CurTXId is 0 then I insert new records. and then call AcceptChanges on the PeopleTable.now if I have an error, for example conversion from null to Decimal causes an error and the first insert occurs before the error. now i have a row inserted but AcceptChanges hasn't been called yet.then i click save again and the insert happens again since the rowstate hasn't changed.how should I handle this?[code]

View 1 RepliesI have datagridview1 which contains data and what I want to do is get the data from first selected row then carry out MyRoutine and then do the same for the next selected row until their is no data in:
RW.Cells(2).Value.ToString

This is what I have come up with so far: But I can't get it to move on to the next selected row once it does the first.

But when I select several rows using the mouse the "DataGridView5_MultiSelectChanged" event is not fired, I must have a property not set correctly, Multiselect is set to true. There are properties for AllowUser to add/delete rows etc, but none for selecting rows.
I have a gridview which gets its input from a database with sql. There is a column with checkboxes in the gridview, so you can select which row you want to export. There is also a column that's called "Project Number". When you push the button "Export" the program should figure out which row is selected, get the project number from this row and connect to the database to get the data from the selected projectnumber. I already got the part where it gets the selected checkboxes. But I'm stuck at the part where it gets the projectnumber from the selected row. Must be something with Datakeys I think.

Dim Count = (dgvProfileURLs.SelectedRows.Count)
MsgBox(Count)
[code]....
This code seems right but its not working. It's giving me an "Index out of range" error. If I change the upper bound of the loop to "(Count - 2)" the code works, it just deletes all except 1 selected row. So can't figure out why "(Count - 1)" doesn't work.
I 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 am using VB2008 and working with DataGridView and Xml file. I can add and delete rows in DGV and save it to the Xml file with no problem. What I would like to be able to do, is to save only the selected rows in my DataGridView1 to a new (different) XML file.
View 4 RepliesIn RowCreated of the GridView i add following script to select a row:
Select Case e.Row.RowType
Case DataControlRowType.DataRow
e.Row.Attributes("onclick") = Me.Page.ClientScript.GetPostBackClientHyperlink(Me.MainGrid, "Select$" & e.Row.RowIndex)
End Select
This works like a charm(i thought).But when i debug the SelectedIndexChanging and the following SelectedIndexChanged events, i observe that the RowState of the selected Row switches from normal{0}/alternate{1} to 3 instead of selected{2}. This occurs between SelectedIndexChanging and SelectedIndexChanged. Why does this happen? The next time i programmatically set the selectedIndex(f.e. after a new row was created), i have two rows that are selected and no (un-hacky) way to deselect the old in RowDataBound, because of the invalid RowState of 3(should only be 0,1,2,4 or 8).

It does count the selected rows, but it always throws out the error saying "ArgumentOutOfRange Exception", or something along those lines. For example, if I selected a row, it will output the results of that row. But the loop goes on. I tried everything I can but to no avail. I specifically want to select multiple rows, and I can achieve that if someone can assist me with this simple "problem" I have.
