Managing Text Fields in DataGridView
I am working on a datagridview in C # on a windows application. I want to add textbox controls to DataGridView. So when we run it, the textbox should be displayed in the gridview and we can put a value in it and there are 3 columns in my grid and I want to add a new row to the grid when I click the tab on the third column of the gridview.
How to do it?

It is difficult to give an exact answer since your question is not detailed enough and is rather general, but to get the text fields in yours DataGridView
you need to add some examples DataGridViewTextBoxColumn
to the collection DataGridView
Columns
. This will cause them to be filled with text boxes on each line.
To detect when the user clicks a tab on the third column, you can add a fourth column 1-2 pixels wide and detect that it received focus (almost definitely from the tab key pressed) using an event OnCellEnter
.
Good luck!

So, for "displaying default textboxes for your question, here's the skinny one:
In GridView-> Edit Columns, add the columns you want to use explicitly. Then click the Convert this Field to TemplateField link. This will allow you to customize the generated HTML for these cells. Say "OK. Then go to GridView-> Edit Templates. For your favorite column, copy the ItemEditTemplate to the ItemTemplate. (The default ItemTemplate. The ItemEditTemplate contains a properly associated edit control.) All of your data fields will now be" editable "by default.
I am assuming you have a submit button. You will need to tell the GridView to update the rows on submit, for example:
For Each r As GridViewRow In GridView1.Rows
Dim mon = System.Int32.Parse(CType(r.FindControl("TextBox1"), TextBox).Text)
If mon <> 0 Then GridView1.UpdateRow(r.RowIndex, False)
Next
Obviously, you need different logic inside, but the basic logic loop / findControl / updateRow should apply.
