I have a Infragistics ultragrid with a checkbox column (no binding on the checkbox column) need the user to only have one check box selected at a time. If a checkbox is checked and the user checks another row I need the first checkbox to uncheck. I am new to infragistic controls, so I apologize if this is a simple property that I have not found. But I have searched the forum and KB to no avail. Do I have to rip through the rows and uncheck all rows but the active one?

IT STILL GIVES A MSGBOX IF I SELECT THE CHECKBOX BOX OR NOT ....My code below will redirect to Google in both conditions: If the user selects the checkbox, then it will redirect to www.google.com, but if a user forgets to check the checkbox then it shows the msg box with an ok button. When I click on ok it should redirect to www.google.com
I want When a user forgets to check any of the checkboxes to show a msgbox with an ok button and stay on the same page. Otherwise if user selects any of the checkboxes then redirect to google

Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime

I have some DataGridView code written in vb.net. (Nothing is attached to a datasource.)The 4th column is a checkbox cell.How do I detect if that checkBox is checked or unchecked?This code strangely reports TRUE or FALSE at random times. It even turns ON the checkbox in rows other than the row I clicked in. (Huh?)
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim whichGrid As DataGridView = CType(sender, DataGridView)
[code].....
I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.

I've got a form with parent-child setup. The parent displays name and other demographic info.The child displays multiple addresses, one row at a time. There can only be one primary address for a name and this is designated by a checkbox at the top of the child form.If the user wants to change the primary address to another address,then they find the other address and click on the checkbox.The form checks the other addresses and if one is found that is designated as primary,the user is warned that one already exists and prompts them to change it.
So for example, a name has 2 addresses, the 2nd being the primary address.The user wants to change the 1st address to be primary.They click on the Primary Address checkbox for the 1st address.A warning displays that there is already an address listed as primary.The user then answers the prompt to change the 1st address to the primary address.The checkbox for the 2nd address will be unchecked and the checkbox will be checked for the 1st address.My problem is getting the checkbox unchecked for the 2nd address.If I close the form and reopen, then the checkbox is unchecked.How do I refresh the checkbox for the 2nd address?Here is the code I'm using to find if an address has already been marked as primary:[code]......

My DGV has MultiRowSelect = True
I have 4 things I am trying to overcome when loading the DGV and when clicking on a row.
1. When the DGV loads, the first row is Selected by default. I would prefer that it not be since that row may not be needed to be selected and mistakenly left selected.
2. Column(0) contains an UnBound CheckBox, when I click it, I want the row to be Selected
3. When I click on the DGV Row, I want the CheckBox to be marked either True or False depending on the state before the row click and the row selected or unselected.
4. Bypassing the need for Ctrl or Shift to select multiple rows.

I have a datagrid, with an unbound checkbox column. How can I get a range select use shift and ctrl keys that will check the checkbox?The moment you check a box, it selects only that row, so the rows selected are down to just the row you clicked on. I've been playing with several events and settings and I can't seem to get it. Can anyone point me in the right direction?When your problem is solved, add (RESOLVED) to the end of your topic. This will save the guru's time and be able to solve more problems. Remove the question mark icon as well.

Actually today I opened my yahoo mail and I saw 2030 messages, too much spam right. What I did I had to delete them all and it took me time. So right now I decided to make a program by using web browser in vb.net. I want to select all the messages and then delete them automatically "Its time consuming." I really don't have much experience with web browser. I mean I can do simple things like filling forms, submit event and so on... But I don't know how to select all the messages on a check box. How can I get started?

I have a DataGridView with a checkbox column. I want to capture the value of the checkbox immediately when user changes it by clicking. I tried several events (CellValueChanged, CellClicked, CurrentCellDirtyStateChanged etc.) but nothing worked.
This is my code:
If dgvIDsTBC.CurrentRow.Cells(2).Value = True Then
MsgBox("True")
End If

I am creating a program that requires the user to click a checkbox and then select a date in a Date Time Picker Control. There will be up to 20 entries. I need to know how to take all of the dates entered and display on a different form the latest date selected by the user from all the entries on a form. All the options will be training selected and when the last training item is selected and a date entered I need to be able to output the training completion date which will be the latest date entered in the form.

I have a datagridview that is bound to a binding source.I used the following code to add a checkbox column to the datagridview:
Imports System.Windows.Forms
...
Dim newcolumn as DataGridViewCheckBoxColumn
Datagridview1.Columns.Add(newcolumn)
The checkbox column shows up successfully, but when I try to click any of the checkboxes,nothing happens.The cell remains unchecked.It blinks, so I know that it is acknowledging the click, but the checkbox state does not change.

I have a pre-existing database which I am coding to, so I can't change the data stored in the SQL-Server 2005 database. My application uses the DataGridView to maintain the data. There is a yes/no field that I would like to bind a checkbox to. The field is a character field in the database, and holds either Y or N. So, here's the question. I know how to set the column to be a checkbox, I think, but I don't know how to map it so that it reads/stores a "Y" value as checked and a "N" value as unchecked.
