今天在写DataGrid中DropDownList的绑定，客户需要根据值去改变价格信息，发现忘记如何写的了。虽然网上很多了，但自己还是做个笔记，以后查询方便
1.ASPX页面
1
<
asp:TemplateColumn HeaderText
=
“
退还价格类型
“
>
2
<
ItemTemplate
>
3
<
asp:DropDownList ID
=
“
ddlReturnPriceType
“
runat
=
“
server
“
AutoPostBack
=
“
true
“
OnSelectedIndexChanged
=
“
ddlReturnPriceType_SelectedIndexChanged
“
>
4
</
asp:DropDownList
>
5
</
ItemTemplate
>
6
<
ItemStyle HorizontalAlign
=
“
Center
“
/>
7
</
asp:TemplateColumn
>
<
asp:TemplateColumn HeaderText
=
“
退还价格类型
“
>

<
ItemTemplate

AutoPostBack=”true”一定不能忘记了！
2.1 CS页面DropDownList动态绑定
1
foreach
(DataGridItem item
in
myGrid.Items)
2
{
3
DropDownList ddlReturnPriceType
=
(DropDownList)item.FindControl(
“
ddlReturnPriceType
“
);
4
ddlReturnPriceType.Items.Clear();
5
ddlReturnPriceType.DataSource
=
AppEnum.GetReturnPriceType();
6
ddlReturnPriceType.DataValueField
=
“
key
“
;
7
ddlReturnPriceType.DataTextField
=
“
value
“
;
8
ddlReturnPriceType.DataBind();
9
｝
foreach
(DataGridItem item
in
myGrid.Items)
2
{
3
DropDownList ddlReturnPriceType
=
(DropDownList)item.FindControl(
“
ddlReturnPriceType
“
);
4
ddlReturnPriceType.Items.Clear();
5
ddlReturnPriceType.DataSource
=
AppEnum.GetReturnPriceType();
6
ddlReturnPriceType.DataValueField
