grid view combobox

Question

how to add items to a data grid view combo box

Are you looking to databind, manually (in the designer), or programatically add the items? — lc., Jan 15 '09 at 14:03
And while we're at it, do you want each row to have a different collection of items, or are they the same for the entire column? — lc., Jan 15 '09 at 14:17

You have a very good example here. Basically, the combobox is created and populated independently from the data binding.

This is a very generic question. If you're having more specific problems please let us know.

First add ad dropdownlist to your gridview with a template field like this Make sure you add an OnRowCreated Event to your gridview

<asp:GridView ID="GridView1" runat="server" OnRowCreated="GridView1_RowCreated">
<Columns>
                        <asp:TemplateField HeaderText="Prerequisite Course">
                            <ItemStyle HorizontalAlign="Center" />
                            <ItemTemplate>
                                <asp:DropDownList ID="ddlPrerequisiteCourseCode" runat="server">
                                </asp:DropDownList>
                            </ItemTemplate>
                        </asp:TemplateField>
</Columns>
  </asp:GridView>

Next in code behind Add a GridView1_RowCreated Event to your GridView

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        {

                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    // Bind drop down to PrerequisiteCourseCodes
                    DropDownList ddl = (DropDownList)e.Row.FindControl("ddlPrerequisiteCourseCode");
                    ddl.DataSource = PrerequisiteCourseCodeList;
                    ddl.DataBind();
                }

        }
