I'm working in Winform application.
I want to make a listview with multiple columns. In which the first column should contain string, the next column should contain textbox for input and output,the next column should contain button.
The main idea is the user should select the row with description,textbox,button. Once he selects the listview, he click on the button and a packet will be sended to device connected to ma com port and display the response in the textbox provided to that row in the listview.
It is possible to add multiple textboxes and buttons to all column.
Looks like your requirement is asking for DataGridView. Take a look at how to use the control on MSDN or any other place of your choice.

By default, when selecting values in a UWP DataGrid the entire row is selected/highlighted. On top of this, you are unable to click and drag to select multiple cells. Pressing CTRL+LClick or Shift+LClick will add rows to the selection, but even this does not allow for multiple cells to be selected.
Is there a way to allow the user to select individual cells? Furthermore, is there a way to allow for a click and drag to select multiple cells within the created rectangle?
UWP DataGrid - Individual Cell Based Selection?
I have to say currently there is no such SelectionUnit api that use to select multiple individual cell,
UWP DataGrid selection model only contains extended and single. It could only use to select entire row. if you want to this feature, I'd suggest you submit a feedback/feature request about this API/feature in the Feedback Hub. You could find the Feedback Hub in the Start Menu. Please select Developer Platform->API Feedback as the category when you submit your request. The related team will check the request.
I'm working with DataGridView in C#. I fill it with a table from database using BindingSource. After filling the DataGridView I need to add a row of checkboxes that should be first in the table, to enable data filtering in future.
I mean: for example after clicking "Load" button I get DataGridView filled with 4 columns of data and the first row should consists of checkboxes.
I confused. I use
DataGridViewCheckBoxCell checkCell = new DataGridViewCheckBoxCell();
SourceDGV.Rows.Add(checkCell);
I mean here:
But after clicking load button it says You can't add rows to databounded DataGridView
Sorry if ecxeption translated wrong, I translated it from Ukrainian.
Any help appreciated.
Am afraid, there is no concept of whole rows to be of some type(checkbox in your case) in DataGridView. It is other way around. You can have whole column to be of checkbox type. You'd use DataGridViewCheckBoxColumn for that.
Showing checkboxes in whole row even makes no sense for me: Assume you have data bounded Person object to the DataGridView. So there will be columns like Name, Age, Address. Now, on what basis you show checkbox in the row? How can a Name be converted to a bool(which is what checkbox needs as a value)?
One workaround I can think of would be, handle custom painting, If First row paint checkboxes over there and manually handle their click events. But am pretty sure it's not gonna be easy.
I have 2 Datagrids on the same form. One of the Datagrids holds data e.g. Policy Number, name, date etc... and I want to be able to drag a single row of data, including all the cells in that row, on top of a user listed in another Datagrid which will then send all that data and the user to another table in an SQL database. (Basically assigning a Policy to a user).
I know how to create the table in SQL but I am unsure how to make the drag and drop work and how to get the data from both data grids collectively.
Try to imagine your solution based on a series on events. My example is very basic, you will need to flesh it out.
DragLeave DataGridView1
Here you want to grab details of the row which has selected.
Then...
DragEnter DataGridView2
Here you want to use your SQL to perform an INSERT to the actual table, based on what has been dragged. If there are no errors, you probably also want to remove the dragged data from the first view.

Hint: I would change the SelectionMode of the first DataGridView to FullRowSelect.
I am using Win forms and have a databound DataGridView which has around 31 columns.
AllowUserToOrderColumn is set to true. But since the number of column is 31 its quite difficult for the user to move columns from one end to another.
so I want to create a form which will display all the columns of the datagridview and with the click of up down button allow them to change the order.
I have named my textBox(readonly) from textbox0 to textbox30.
Is there any way to display the column order in text boxes.
Like when we click EditColumns in the designer view.
Certainly:
Look at the DisplayIndex of the columns -> http://msdn.microsoft.com/en-us/library/wkfe535h.aspx
With this, you should be able to read them and change them by code.
Hello I have a datagridview with many rows. I would like to be able to click on a cell and type some letters and have a matching row get selected (or scroll to it). I can sort out which column it is sorting to, but right now there is no 'search' capability.
When you open a Window's Explorer window and click on a file, you can start typing to have the selection move to the file/folder that matches your keystrokes.
Is this possible with the datagridview?
What I meant was the DataGridRow.IsSelected property. Since you said you know which rows contains your results, you can call DataGridView.ClearSelection() and then set the IsSelected property of the row that contains the data to true.
