Gridview怎么在里面编辑模板里加多个Dropdownlist?

[fengaiyue1314]

加一个我会，加多个我就不会啦。

加一个我会。

<asp:TemplateField HeaderText="终端编号" FooterText="DCT_Id" >
<ItemTemplate ><%# Eval("DCT_Id") %></ItemTemplate>
<EditItemTemplate>
<asp:HiddenField ID="HiddenField1" runat="server" />
<asp:DropDownList ID="DropDownList1" runat="server">
</asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>



加多个呢？高手请给一个合理的方法。

没编辑的时候还得要显示，点编辑的时候变成dropdownlist.

直接再拖一个到EditItemTemplate中不行？
你再拖一个，运行试试。哎。。

<ItemTemplate>
<asp:DropDownList ID="ddlSort" runat="server" Width="98%">
</asp:DropDownList>
<asp:HiddenField ID="Hd_Sort" runat="server" Value='<%# Eval("BalSort")%>' />
</ItemTemplate>
protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex != -1)
{ if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState.Alternate | DataControlRowState.Edit))
{
((DropDownList)e.Row.FindControl("ddlSort")).SelectedValue = ((HiddenField)e.Row.FindControl("Hd_Sort")).Value;
}
}
}

protected void gv_RowEditing(object sender, GridViewEditEventArgs e)
{
gv.EditIndex = e.NewEditIndex;
string strSort = ((DropDownList)gv.Rows[e.NewEditIndex].FindControl("ddlSort")).SelectedValue.Trim();


gv.EditIndex = -1;
BindData();
}

你这表示一个单元格里两个Dropdownlist 并且表头怎么办？

你这相当于两个字段对应的表头都是HeaderText="终端编号"

你说的和我问的不一样，但是还可以这样写，基本上是一样的，可以互相学习下。

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns ="False"
DataKeyNames="A_Id"
onrowcancelingedit="GridView1_RowCancelingEdit"
onrowdatabound="GridView1_RowDataBound"
onrowdeleting="GridView1_RowDeleting"
onrowediting="GridView1_RowEditing"
onrowupdating="GridView1_RowUpdating">
<Columns>
<asp:TemplateField HeaderText="终端编号" >
<ItemTemplate ><%# Eval("DCT_Id") %></ItemTemplate>
<EditItemTemplate>
<asp:HiddenField ID="HiddenField1" runat="server" />
<asp:DropDownList ID="DropDownList1" runat="server">
</asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>

后台：

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
Bing();
}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if((e.Row.RowState & DataControlRowState.Edit)==DataControlRowState.Edit)
{
HiddenField hd = e.Row.FindControl("HiddenField") as HiddenField;
DropDownList lst = e.Row.FindControl("DropDownList1") as DropDownList;
lst.DataSource = AmmeterInfo.SelectDCT();
lst.DataValueField = "DCT_Id";
lst.DataTextField = "DCT_Name";
lst.DataBind();
lst.SelectedValue = hd.Value;
Bing();
}
}


手高要明白我问的问题呀，也就是有多列 当Gridview 出显的时候 是有内容地，当点编辑时出现Dropdownlist . 并且是多个Dropdownlist!!!

一个我会的。多个现在不会。

[fengaiyue1314]

在友友们提示的基础上我又这样写啦下。
运行没问题，就是点击 编辑没反应。大家帮我看看错在哪里，我现在正做项目，时间有点急！！

前台：
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="A_Id"
OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowDataBound="GridView1_RowDataBound"
OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating">
<Columns>
<asp:TemplateField HeaderText="终端编号">
<ItemTemplate><%# Eval("DCT_Id") %></ItemTemplate>
<EditItemTemplate>
<asp:HiddenField ID="HiddenField1" runat="server" />
<asp:DropDownList ID="DropDownList1" runat="server">
</asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="用电方案">
<ItemTemplate><%#Eval("UP_Name")%></ItemTemplate>
<EditItemTemplate>
<asp:HiddenField ID="HiddenField2" runat="server" />
<asp:DropDownList ID="DropDownList2" runat="server">
</asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>

后台：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if((e.Row.RowState & DataControlRowState.Edit)==DataControlRowState.Edit)
{
HiddenField hd1 = e.Row.FindControl("HiddenField1") as HiddenField;
DropDownList lst1 = e.Row.FindControl("DropDownList1") as DropDownList;
lst1.DataSource = AmmeterInfo.SelectDCT();
lst1.DataValueField = "DCT_Id";
lst1.DataTextField = "DCT_Name";
lst1.DataBind();
lst1.SelectedValue = hd1.Value;
//
HiddenField hd2 = e.Row.FindControl("HiddenField2") as HiddenField;
DropDownList lst2 = e.Row.FindControl("DropDownList2") as DropDownList;
lst2.DataSource = AmmeterInfo.SelectPlan();
lst2.DataValueField = "UP_Id";
lst2.DataTextField = "UP_Name";
lst2.DataBind();
lst2.SelectedValue = hd2.Value;
Bing();
}
}

就按我10楼的例子，你变下给我看。像这玩意没必要保留吧。友友弄一个给我看。

自己多试试，先按自己的想法加进去，不行再问别人怎么解决。
解决问题不是最终目的，解决问题的思考过程才是最重要的。
