Use Checkbox For Selecting Multiple Rows From DataGridView?
Sep 24, 2011
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
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.
I generated columns from database and getting cell values from database too. my problem is that for some columns I have to generate checkbox in each cell at runtime.I m using visual studio 2010.
i just need to select from multiple checkboxes, this checkbox contains days from Monday to Saturday. Here is the idea on what will happen if I select Multiple days, it will save on a field on my database with colon(;)

My below is not an error. It just I need an alternative way of doing thing. I have a DataGridView which has a DataSource of DataTable on a Form.

I need to select multiple random rows in DatagridView with keypress.Ex:
Row1 -selected Row2 -not selected Row3 - selected
I do have part of code that will update certain field in database on keypress, but i have no idea how to create multiple selection and display it on DataGrid.CTRL+Click is nice, but I would like to have option of selecting rows with keypress.In following code I am checking if certain field is marked for selection(i want to give user an option to start selection, exit program then continue selection later) but it allways select all rows in table (even if only one is marked).
Dim NumRow As Integer NumRow = 0 Do Until NumRow = dbtShow.RowCount - 1
[code]....
My question is: What is the best way to select multiple random rows in code?
I have a Windows application form. Directly on the form I have a lable ("Customer Names"), a ComboBox (pulling actually names from a database) , and a Buton to add a customer to the database if i choose. Additionally I have ControlTab(3 tabs) that has "fields" and its own Buttons to insert data into a different table. The first 2 tabs have textBoxes, which are completely functional, but the 3rd tab has a "DataGridView"
I have a datagridview binded to a list of objects... I have a column named Selected containing a checkbox. When these checkboxes are checked and a button is clicked, I want those particular rows to be removed. I initially set it out to iterate through the grid's rows and RemoveAt(SelectedRowIndex) but of course when it removes an object from the List of objects at the selected row (IE Row 1, 4 and 6), the list indexes change and it fails to work properly when it goes to remove the next row since Row 4 is now row 3 in the list...? What is the best way to do this?
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."
i have a data base where i am selecting rows between two dates, but what i need to do is also get another another row if it has the same ID so: If i put the date as: 01/02/2011 - 01/02/2011
I am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.
how i can get the grid to select a row by clicking on any cell in the row?
The only way i can do this at the moment is by setting the AutoGenerateSelectButton property to True, but this adds a column to the grid with a crude "select" hyperlink and only selects the row if the word "Select" is cliked on.
Whenever a row is selected in my GridView, I want to take the ID field of my gridview's dataset and form a unique URL with it (use a ?id=1234 parameter). In the Page_Load event I have the following code:
