I have DetailsView on my page. I set DefaultMode="Edit". Now i want to get value that user will edit in this cell.

<asp:DetailsView ID="dvApplicantDetails" runat="server" 
            AutoGenerateRows="false" DataKeyNames="ApplicantID" DefaultMode="Edit" 
            onitemcommand="dvApplicantDetails_ItemCommand" >
        <Fields>
            <asp:BoundField DataField="ApplicantID" HeaderText="ApplicantID" ReadOnly="true"/>
            <asp:BoundField DataField="FirstName" HeaderText="First Name" />
            <asp:BoundField DataField="LastName" HeaderText="Last Name" />

            <asp:CommandField ButtonType="Button" ShowEditButton="true" EditText="Update" ShowCancelButton="false" />
        </Fields>
        </asp:DetailsView>

I've tried many ways to get this value, such as:

protected void dvApplicantDetails_ItemCommand(object sender, DetailsViewCommandEventArgs e)
{
    if (e.CommandName == "Update")
    {
        string firstName = dvApplicantDetails.Rows[1].Cells[1].Text;
        string lastName = dvApplicantDetails.Rows[2].Cells[1].Text;
    }
}

But it doesn't work... How to get this value using this mode. I know that i can use <ItemTemplate> instead of <BoundField>, but anyway it should be some way to get this value from this field. Help please! Thank you!

Unfortunately, trying to access the Text of ..Cells[1] is not what you are looking for. You need the value of the TextBox control within that cell:

protected void dvApplicantDetails_ItemCommand(object sender, DetailsViewCommandEventArgs e)
{
    if (e.CommandName == "Update")
    {
        string firstName = ((TextBox)dvApplicantDetails.Rows[1].Cells[1].Controls[0]).Text;
        string lastName = ((TextBox)dvApplicantDetails.Rows[2].Cells[1].Controls[0]).Text
    }
}
