使用Button从GridView获取ID [英] Get Id from GridView using Button

问题描述

 < div class =row> 
< asp：GridView ID =gvIndexCssClass =table table-bordered table-responsiverunat =serverAllowPaging =TruePageSize =10AutoGenerateColumns =FalseAutoGenerateEditButton =False OnRowCommand = gvIndex_RowCommand > 
 
<列> 
< asp：BoundField DataField =IdHeaderText =NúmeroHtmlEncode =false> //这是我的ID字段
< FooterStyle Width =200px/> 
< / asp：BoundField> 
< asp：BoundField DataField =NombreHeaderText =NombreHtmlEncode =false> 
< FooterStyle Width =400px/> 
< / asp：BoundField> 
< asp：BoundField DataField =DireccionHeaderText =DirecciónHtmlEncode =false> 
< FooterStyle Width =400px/> 
< / asp：BoundField> 
< asp：BoundField DataField =PuestoHeaderText =PuestoHtmlEncode =false> 
< FooterStyle Width =400px/> 
< / asp：BoundField> 
< asp：BoundField DataField =FechaHeaderText =FechaHtmlEncode =false> 
< FooterStyle Width =175px/> 
< / asp：BoundField> 
< asp：BoundField DataField =CorreoElectronicoHeaderText =CorreroElectrónicoHtmlEncode =false> 
< FooterStyle Width =350px/> 
< / asp：BoundField> 
 
< asp：TemplateField ItemStyle-Horizo​​ntalAlign =CenterHeaderText =Edición> 
< ItemTemplate> 
 
< asp：LinkBut​​ton ID =EditarIngresoOnClick =EditarIngreso_ClickCommandArgument =<％Eval（'Id'）％> CommandName =SelectRowCssClass =btn btn-primaryrunat =server> Editar< / asp：LinkBut​​ton> //我想要获得Id 
的值<％ - < asp：HyperLink ID =EditarIngresoBorderStyle =NoneOnClick =EditarIngreso_ClickText =Editarrunat =server> ;超链接< / ASP：超链接>  - ％GT; 
<％ - < a id =EditarIngresorunat =serverstyle =text-decoration：underline; border：none> Editar< / a>  - ％> 
< / ItemTemplate> 
< / asp：TemplateField> 
< /列> 
 
< / asp：GridView> 
< / div> 
  

正如你所看到的，我想在这一行中获得Id的值：

 < asp：LinkBut​​ton ID =EditarIngresoOnClick =EditarIngreso_ClickCommandArgument =<％Eval（'Id'）％> CommandName =SelectRowCssClass =btn btn-primaryrunat =server> Editar< / asp：LinkBut​​ton> 
  

但我不知道这有什么问题，我试着用这个方法来解决它：

  protected void gvIndex_RowCommand（object sender，GridViewCommandEventArgs e）
 {
 MyID.Value = e.CommandArgument的ToString（）; 
} 
  

但我只收到<％Eval（ 'Id'）％>而不是我的ID到 MyID.Value

任何帮助是非常感激。问候

解决方案

首先缺少＃

 < asp：LinkBut​​ton ID =EditarIngresoOnClick =EditarIngreso_ClickCommandArgument =<％＃Eval（'Id'）％> CommandName =SelectRowCssClass =btn btn-primaryrunat =server> Editar< / asp：LinkBut​​ton> 
  

在Gridview标签中

add DataKeyNames =Id

 < asp：Gridview id = gvIndexDataKeyNames =Id/> 
  

然后OnClick LinkBut​​ton

  protected void EditarIngreso_Click（object sender，EventArgs e）
 {
 LinkBut​​ton btn = sender as LinkBut​​ton; 
 GridViewRow row = btn.NamingContainer as GridViewRow; 
 
 string pk = gvIndex.DataKeys [row.RowIndex] .Values [0] .ToString（）; 
 //这里PK是你的ID 
 //将它转换为Int32 
} 
  

I have a Grid Where I have Id like this:

<div class="row ">
            <asp:GridView ID="gvIndex" CssClass="table table-bordered table-responsive"  runat="server" AllowPaging="True" PageSize="10" AutoGenerateColumns="False" AutoGenerateEditButton="False" OnRowCommand="gvIndex_RowCommand">

                <Columns>
                    <asp:BoundField DataField="Id" HeaderText="Número" HtmlEncode="false"> //This is my Id Field
                        <FooterStyle Width="200px" />
                    </asp:BoundField>
                    <asp:BoundField DataField="Nombre" HeaderText="Nombre" HtmlEncode="false">
                        <FooterStyle Width="400px" />
                    </asp:BoundField>
                    <asp:BoundField DataField="Direccion" HeaderText="Dirección" HtmlEncode="false">
                        <FooterStyle Width="400px" />
                    </asp:BoundField>
                    <asp:BoundField DataField="Puesto" HeaderText="Puesto" HtmlEncode="false">
                        <FooterStyle Width="400px" />
                    </asp:BoundField>
                    <asp:BoundField DataField="Fecha" HeaderText="Fecha" HtmlEncode="false">
                        <FooterStyle Width="175px" />
                    </asp:BoundField>
                    <asp:BoundField DataField="CorreoElectronico" HeaderText="Correro Electrónico" HtmlEncode="false">
                        <FooterStyle Width="350px" />
                    </asp:BoundField>

                    <asp:TemplateField ItemStyle-HorizontalAlign="Center" HeaderText="Edición">
                        <ItemTemplate>

                            <asp:LinkButton ID="EditarIngreso" OnClick="EditarIngreso_Click" CommandArgument="<% Eval('Id') %>" CommandName="SelectRow"  CssClass="btn btn-primary" runat="server">Editar</asp:LinkButton> //There I want to get value of Id
                            <%--<asp:HyperLink ID="EditarIngreso" BorderStyle="None" OnClick="EditarIngreso_Click" Text="Editar"  runat="server">HyperLink</asp:HyperLink>--%>
                            <%--<a id="EditarIngreso" runat="server" style="text-decoration: underline; border: none">Editar</a>--%>
                        </ItemTemplate>
                    </asp:TemplateField>
                </Columns>

            </asp:GridView>
        </div>

As you can see, I want to get value of Id in this line:

 <asp:LinkButton ID="EditarIngreso" OnClick="EditarIngreso_Click" CommandArgument="<% Eval('Id') %>" CommandName="SelectRow"  CssClass="btn btn-primary" runat="server">Editar</asp:LinkButton> 

But I don't know what is wrong with this, I try to get it with this method:

protected void gvIndex_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            MyID.Value = e.CommandArgument.ToString();
        }

But I just receiving "<%Eval('Id') %>" instead my Id into MyID.Value

Any Help is very appreciate. Regards

解决方案

First missing #

<asp:LinkButton ID="EditarIngreso" OnClick="EditarIngreso_Click" CommandArgument="<%# Eval('Id') %>" CommandName="SelectRow"  CssClass="btn btn-primary" runat="server">Editar</asp:LinkButton> 

In Gridview Tag

add DataKeyNames= "Id"

<asp:Gridview id="gvIndex"  DataKeyNames= "Id" />

Then OnClick of LinkButton

protected void EditarIngreso_Click(object sender,EventArgs e)
{
LinkButton btn = sender as LinkButton ;
GridViewRow row = btn.NamingContainer as GridViewRow;

string pk = gvIndex.DataKeys[row.RowIndex].Values[0].ToString();
  // here PK is your ID 
  // Convert it to Int32
}
