I have created a bound DataGridView and then added an unbound checkbox (name=select) for selecting multiple rows. The problem I'm having is the row doesn't actually get selected when I set .selected to true which I'm doing in the CellValueChanged event. When I trace it the code is properly executed but the row is not highlighted when the checkbox is checked and consequently not selected in the grid.There is no mouse or keyboard and the input device is a USB button panel which we built.
Public Sub dataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) Handles DGV_Categories.CellValueChanged
If DGV_Categories.Columns(e.ColumnIndex).Name = "Select" Then

View 6 RepliesI have aspx gridview with checkbox on evryrow, what is required is whenever we check any of the rows, a query should be launched to change the specific agent -each row consist of agentID, Pass, Status- to Paid Status. using javascriptWhat I need to know is how to loop to get the Checked row and get the ID of the row checked so that I can get THe ID of the Agent in thos row so that I can update its status.using javascriptI found something similar on stackflow:t GridView selected row DataKey in JavascriptBut it is not my case, what is needed is at the check of a checkbox a javascript function should launch through which I could update the selected row in grid view after having the index of this row and this all to avoid refreshing the page.

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?)

I have a listbox that contains several items (the amount of items changes depending on who is using the application). The listbox is setup so the user can select more then one item. I am attempting to submit the user selection(s) to the database. The problem I'm having is that when I loop through the array to find out what is selected, I'm only getting the first item selected (because I cannot deselect it).
For Counter = 0 To lstEmailFreq.SelectedItems.Count - 1
PreferenceKey = lstEmailFreq.SelectedValue 'Get the PreferenecKey for processing
'Next insert new records[code]....
What I think I need is someway to deselect the first item from the listbox so the next loop through will grab the second item and so forth.For example.The user has Product 1 and Product 3 selected.The user clicks a button to submit to the database. I need to know that Product 1 is selected, enter it to the database, deselect it,and then loop back through.When I loop back through I would now see Product 3 selected.
I Have a problem with selecting a row in a datagridview. I want the user to press on the data rowheader of the data gridview of a particular row and then that rows first item are put in a string. But the problem is that if i Select an item another item is still selected. So If I press the mouse button on the row header the previous item is still selected and then the wrong data is in the string. Here is the code under the event of the datagridview mouse click:
Private Sub dataGridView1_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs) Handles DataGridView1.MouseDown
Dim hit As DataGridView.HitTestInfo = DataGridView1.HitTest(e.X, e.Y)

I have a datagridview that is bound to a dataview. I use a textbox to sort the list of data in the datagridview. Once the list is sorted I want to click on a row to populate the textboxes in order to update the data. Problem is once I sort the data I click on say row 3 and it pulls up the orginal data before the data was sorted in the datagrid view. For instance:
Before Sort:
1. betsy
2. james
3. john
After sort:
1. john
2. james
3. betsy
If I double click row 1 it will pull betsy info into my textboxes instead of john. I currently refresh my datagridview after every letter is entered into my textbox. I also reload my dataview and rebind the dataview with the datagridview.
Currently I am using this code to fill my datagrid.
Dim da As New SqlDataAdapter("Select id, name, type, add1 from [company_details]", con)
Try
If Pdetails.Visible = True Then
con.Open()

I have a bound datagridview containing 4 columns. All I want to do is click on a row and then assign the value for each column to other controls (in this case textboxes). My problem is, I'm not sure which Event to use. I don't know how many events I've tried the code below in several different events but none of them are working.[code]
View 5 RepliesI try to select the last row like this:
Dim lastRow As Integer = DGV.RowCount
MsgBox(lastRow)
DGV.Rows(lastRow).Selected = True
The messagebox returns the correct number, but when it comes to select that row it says:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
But if I assign it a row, example: DGV.Rows(5).Selected = True
I have a strange problem with a DataGridView I'm using which is bound to a table in VB.net
I've added a checkbox column to allow a user to tick a bunch of rows that I can then loop through and save off to a different table. All the checkboxes are enabled by default. So it's really a case of unchecking the rows which aren't required.
However, the DataGridView re-enables any checkbox that I click after I click on a checkbox in another row. So in effect, only one row can be unchecked at a time.
EDIT: I forgot to mention this is a Windows form, not an ASP.net application.
I have a DataGridView that is being populated. What I'm trying to accomplish is when I select like 3 rows I click a button and it gives me the "row numbers" for those three rows.

View 2 RepliesIs there a way to make a column unselectable? I can make the column read-only but it would be easier if it was unselectable so the user won't be confused trying to enter data into a read only cell. So if I clicked on a cell in that column or moved into that cell in that column it would jump to the next column, or not focus on the cell at all.
View 4 RepliesWith the two lists (t1s and t2s), I want to display t1s in a DataGridView, and in one column show the T2 property as a comboBox column, which dropdown will show the t2s list such that a new list instance can be selected. T2 has a Name property that should be used for displaying it in the comboBoxColumn.
I'm able to display the dropdown, but remaining a few problems:
1. How to display the correct comboBox "selection" on "load"?
2. How to change the T2 child object instance when combobox selection is made?
3. This is a really basic problem, which suddenly happened and I just couldn't understand what I have changed; The code marked BLUE now just shows empty cells.. While the AutoGenerated columns do show values.. Shouldn't those "manual" columns work?

NB: I'm using Visual Basic.NET?My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid.When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid.So, basically, I want to dynamically display data in one grid based on user selection in another grid.My code looks like this so far...

The above code works like a charm, except that my selecting of the right row does not fire the datagridview 'selectionchanged' event like it would normally do if I just clicked on it manually.
what I need to do to get the grid to fire off this event after selecting a row with code instead of a mouse click?

I need to change the cell type of an unbound datagridview ROW to checkbox type at runtime. Optionally adding a row of all checkboxes or changing the default type to checkbox is also fine. I see many examples for setting a column type to checkbox but I don't see anything that operates at the row level. Even operating at the cell level would be fine.
View 1 RepliesI have the code below which works fine when checkbox at Cell 2 is Checked ie., the date is inserted in Cell 9. Now, when I unclick Cell 2 I want the Cell 9 to be cleared.

I have a tbl called tblProjectpatients which also has 2 fields Yes and No (these have the data type - Bit). These two fields have been populated with false and true values. On my form, I have a datagridview which is populated with various values from tblProjectpatients. The problem am facing is that the checkbox's for Yes and No on the datagridview are empty at runtime eventhough at the backend they have either False or True values. I am expecting the checkbox showing on the datagridview to be either checked or Not Checked depending on the True or false values.
