Datagrid plus drop-down list dropdownlist and dropdownlist

Code in the datagrid:

<Asp: datagrid id = "dgList" runat = "server" ItemStyle-HorizontalAlign = "Center" HeaderStyle-HorizontalAlign = "Center" HorizontalAlign = "Center" PageSize = "5" AutoGenerateColumns = "False" gridLines = "Horizontal" CellPadding = "1" BackColor = "White" BorderWidth = "1px" BorderStyle = "None" BorderColor = "# E7E7FF" Width = 100% OnItemDataBound = "Maid itemdatabound"> <FooterStyle ForeColor = "# 4A3C8C" BackColor = "# B5C7DE"> </FooterStyle> <SelectedItemStyle Font-Bold = "True" ForeColor = "# F7F7F7" BackColor = "# 738A9C"> </SelectedItemStyle> <AlternatingItemStyle BackColor = "# F7F7F7"> </AlternatingItemStyle> <ItemStyle placement = "Center" ForeColor = "# 4A3C8C" BackColor = "# E7E7FF"> </ itemStyle> <HeaderStyle Font-Bold = "True" HorizontalAlign = "Center" ForeColor = "# F7F7F7" BackColor = "# 4A3C8C"> </HeaderStyle> <Columns> <asp: templatecolumn HeaderText = "status"> <itemtemplate> <asp: dropdownlist id = "ItemDropDown" runat = "server" AutoPostBack = "true" OnSelectedIndexChanged = "DropDown_SelectedIndexChanged"/> </itemtemplate> </asp: TemplateColumn> <asp: templateColumn> <ItemTemplate> <asp: Button id = "SaveButton" Visible = "false" runat = "server" CommandName = "save" Text = "save"> </asp: button> </ItemTemplate> </asp: templatecolumn> <PagerStyle ForeColor = "# 4A3C8C" BackColor = "# E7E7FF" Mode = "NumericPages"> </PagerStyle> </asp: datagrid>

Private void InitializeComponent () {this. dgList. itemCommand + = new System. web.

3. How to add a column like this in the DataGrid: A DropDownList column, and the DropDownList of each row can be

Insert a template column in The DataGrid
<Asp: TemplateColumn HeaderText = "drop-down box column">
<ItemTemplate>
<Asp: dropdownlist id = "ddlCopyFileQty" runat = "server" Width = "52px">
<Asp: ListItem Value = "0"> 0 </asp: ListItem>
</Asp: dropdownlist>
</ItemTemplate>
<HeaderStyle Width = "60px"/>
</Asp: TemplateColumn>
Your question says "and every row's DropDownList can be used" is still incomplete. I guess whether to obtain the DropDownList of each row for value assignment or value operation:
Foreach (DataGridItem dt in dgInfoList. Items)
{
DropDownList ddlCopyFileQty = (DropDownList) dt. Cells [3]. FindControl ("ddlCopyFileQty ");
DdlCopyFileQty. SelectedValue = dt. Cells [6]. Text;
}
 
How can I dynamically insert data in the drop-down box set in the DATAGRID in aspnet?
