就一个Gridview问题全论坛的高手都解决不了？？？我就不信，第三次发同一个问题。

[fengaiyue1314]

大家看清我的问题别再回答我，别不看题目就回复。！！



<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>

看这段代码在gridview里面能这样用不？ 我运行啦不会报错！·

我的目的：

看这<asp:TemplateField HeaderText="终端编号">
<ItemTemplate><%# Eval("DCT_Id") %></ItemTemplate>

------
和这

<asp:TemplateField HeaderText="用电方案">
<ItemTemplate><%#Eval("UP_Name")%></ItemTemplate>

就是为了，在gridview显示！当然可以直接绑，后面还有目的。

我想实现，当我点编辑的时候变成dropdownlist。

当然如果是一个，我会绑定，一个dropdownlist+HiddenFiel刚好。后台我会绑定。因为我正在项目前面只要是绑定一个的都没问题。

现在这个gridview要多个dropdownlist .现在我只试用两个看看，如果这两个成功的话，绑定100个也行对吧。

对于高手来说，这样说他应该明白的我目的啦吧。

我这个问题第三次发现在还没人帮我。

如果我这样不行，你只要知道我的目的，把我上面的改下给我我就知道行不。。谢谢，大家加油。

我这样运行不会报错。当我点编辑没反应。这也是我头痛的事，我一直在想gridviewi不能这样用。

可又没人告诉我这样用不行。后台我会绑定。

使用过可以这样使用
onrowcommand="gv_RowCommand"
onrowdatabound="gv_RowDataBound" onrowdeleting="gv_RowDeleting"
onrowediting="gv_RowEditing" onrowupdating="gv_RowUpdating"
<asp:TemplateField HeaderText="操作" ItemStyle-HorizontalAlign="Center" ShowHeader="False">
<HeaderStyle Width="20%"></HeaderStyle>
<EditItemTemplate>
<asp:LinkButton ID="LinkButton5" runat="server" CausesValidation="True" CommandName="update">保存</asp:LinkButton>
<asp:LinkButton ID="LinkButton4" runat="server" CausesValidation="False" CommandName="cancel">取消</asp:LinkButton>
</EditItemTemplate>
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="edit" CausesValidation="false" OnClientClick="return confirm('确认要编辑吗？');">编辑</asp:LinkButton>
<asp:LinkButton ID="LinkButton2" runat="server" CommandName="delete" CausesValidation="False" OnClientClick="return confirm('确认要删除吗？');">删除</asp:LinkButton>
<asp:LinkButton ID="LinkButton3" runat="server" CommandName="Select" CausesValidation="False" Visible="false" >选取</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>

我第一次发时40分，第二次100，
现在我再想弄100分出来可是前几次没结贴弄不了那么多。汗。哥也是刚玩这个论坛，如果感觉不行我不会在这里玩啦

你这样写可能还有用，明天 我看看再说，谢谢……

[fengaiyue1314]

这是我的后台代码。

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 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();
}
}

这么些没有问题 点击编辑的时候使用的是EditItem...

[wuyq11]

结合我在前几个帖子的代码就可以了
protected void gv_RowEditing(object sender, GridViewEditEventArgs e)
{
gv.EditIndex = e.NewEditIndex;
BindData();
}
protected void gv_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
gv.EditIndex = e.RowIndex;
int id = int.Parse(gv.DataKeys[e.RowIndex].Value.ToString());

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

几乎集Girdview所有技术为一体的超级变形金刚

[fengaiyue1314]

谢谢各位参与者。

我和思路没问题，前台没问题。我就是在GridView1_RowDataBound，里面手误写啦个bing().

结贴。

现在成熟代码如下，用于多个dropdownlist.

<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>
<asp:BoundField DataField="A_Id" HeaderText="户编" />
<asp:BoundField DataField="Cus_Name" HeaderText="户名" />
<asp:BoundField DataField="Cus_Address" HeaderText="地址" />
<asp:BoundField DataField="Cus_Tel" HeaderText="电话" />
<asp:BoundField DataField="A_Type" HeaderText="表类型" />
<asp:BoundField DataField="A_PropertyNum" HeaderText="资产编号" />
<asp:BoundField DataField="A_PhaseSequence" HeaderText="相序" />
<asp:BoundField DataField="A_SingleOrDouble" HeaderText="费率类型" />
<asp:BoundField DataField="A_CommAddress" HeaderText="通信地址" />
<asp:BoundField DataField="A_BarCode" HeaderText="条形码" />
<asp:BoundField DataField="A_TP" HeaderText="总/分" />
<asp:CheckBoxField DataField="A_State" HeaderText="停用标志" Text="停用" />
<asp:CommandField ButtonType="Button" ShowEditButton="True" />
<asp:CommandField ButtonType="Button" ShowDeleteButton="True" />
</Columns>
</asp:GridView>

后台我主要结解决这两个dropdownlist.

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 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();
}
}

如果你们要更多的dropdownlist .你像我上面写多个
<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>

在后台的GridView1_RowDataBound里面一一绑定就行啦。

谢谢大家。
