hi dear

If you are fetching data for combo from database then you can use union query for select "Select combobox" like

SQL

select Val,Txt from tblComboMaster
union All
select '0' as Val, 'Select combobox' as Txt
order by Val

after it bind selected value = 0 from combobox

Thanks

Hi ,
Check this

XML

<div>
           <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
        onrowdeleting="GridView1_RowDeleting">
        <Columns>
            <asp:BoundField DataField="dd" HeaderText="dd" SortExpression="dd" />
            <asp:TemplateField HeaderText="ddd" SortExpression="ddd">
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text='<%# Bind("ddd") %>'></asp:Label>
                </ItemTemplate>
                <EditItemTemplate>
                    <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("ddd") %>'></asp:TextBox>
                </EditItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField HeaderText="cate" SortExpression="cate">
                <EditItemTemplate>
                    <asp:DropDownList ID="DropDownList1" runat="server"
                        DataSourceID="SqlDataSource12" DataTextField="cate" DataValueField="id"
                        SelectedValue="<%# Bind('cate') %>">
                    </asp:DropDownList>
                    <asp:SqlDataSource ID="SqlDataSource12" runat="server"
                        ConnectionString="<%$ ConnectionStrings:testConnectionString %>"
                        SelectCommand="SELECT * FROM [cate]"></asp:SqlDataSource>
                </EditItemTemplate>
                <ItemTemplate>
                    <asp:Label ID="Label2" runat="server" Text='<%# Bind("cate") %>'></asp:Label>

my question is in winforms not asp.net

please see my edited question

Solution 3

Try this :-

//Add Combo Box Column
 DataGridViewComboBoxColumn comboBoxCol = new
 DataGridViewComboBoxColumn();
 comboBoxCol.Name = "Name1";
 comboBoxCol.HeaderText = "HeaderText1";
 DataGridView1.Columns.Add(comboBoxCol);
 comboBoxCol.Width = 80;
 //comboBoxCol.ReadOnly = false; //Enable Editing

 //Now you can add multiple columns to the combobox.
 comboBoxCol.Items.Add("COLUMN1");
 comboBoxCol.Items.Add("COLUMN2");
 comboBoxCol.Items.Add("COLUMN3");

Hope This Help !!

First I added my items to combobox(i fetched data from sql server database with datareader and added them to combo box) then i added this properties to my datagridviewcolumn(dgv_col) :

dgv_col.DataPropertyName="name"
dgv_col.DisplayMember="name"
dgv_col.ValueMember="id"

name is a field in my table and id is the identity for each name

And Finally it Solved :)
