如何在DetailsView按钮字段中添加onClick事件？ [英] How to add onClick Event in DetailsView Button Field?

问题描述

嘿，



我有一个detailview，我想使用详情视图中使用的按钮的onClick事件，有什么办法吗？

其次，如何从detailsView获取特定数据库（如IDNo）并将值放在某个字符串中？



如果我有一个详细视图包含（ IDNo，学校，学院，大学，（按钮字段），如果点击按钮字段，那么它从详细信息查看IDNo



任何帮助？

解决方案

你可以使用OnItemCommand事件的detailsview之后给那个按钮的CommandName，在那个事件的后面你可以那个CommandName像

  if （e.CommandName ==  < span class =code-string> xyz）
 {
 
  //  你的逻辑 
} 

这是一个样本试试这个

 <   asp：GridView     ID   =  GridView1    runat   =  server    AllowPaging   =  True  
   
                   AutoGenerateColumns   =  False     DataKeyNames   = < span class =code-keyword> ProductID  
   
                < span class =code-attribute>   DataSourceID   =  SqlDataSource1    onrowdatabound   =   GridView1_RowDataBound >  
 <  列 >  
 
 <   asp：BoundField     DataField   =   ProductID    HeaderText  < span class =code-keyword> =  ProductID  
  < span class =code-attribute> 
                                   InsertVisible   =  False    ReadOnly   =  True    SortExpression   =  ProductID    /  >  
 <   asp：BoundField     DataField   =  ProductName    HeaderText   =  ProductName  
   
                                   SortExpression   =  ProductName    /  >  
 < ;   asp：TemplateField     HeaderText   =  del >  
 <   ItemTemplate  >  
 <   asp：按钮    ID   =  Button1    runat   =  server    onclick   =  Button1_Click   文本  = 按钮    /  >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 <   /列 < span class =code-keyword>>  
 <   / asp：GridView  >  

代码落后

  protected   void  Button1_Click（ object  sender，EventArgs e）
 {
按钮btn =（按钮）发送者; 
 GridViewRow gvr =（GridViewRow）btn.NamingContainer; 
  int  index = gvr.RowIndex; 
  string   value  = GridView1.Rows [index] .Cells [ 1 ]文本。 
}

Any help ?

解决方案

You can use OnItemCommand event of detailsview after that give the CommandName of that button ,in behind in that that event you can that CommandName like

if(e.CommandName == "xyz")
{

// you logic
}

Here is a sample try this

<asp:GridView ID="GridView1" runat="server" AllowPaging="True"

        AutoGenerateColumns="False" DataKeyNames="ProductID"

        DataSourceID="SqlDataSource1" onrowdatabound="GridView1_RowDataBound">
        <Columns>
            
            <asp:BoundField DataField="ProductID" HeaderText="ProductID"

                InsertVisible="False" ReadOnly="True" SortExpression="ProductID" />
            <asp:BoundField DataField="ProductName" HeaderText="ProductName"

                SortExpression="ProductName" />
            <asp:TemplateField HeaderText="del">
                <ItemTemplate>
                    <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

Code behind

protected void Button1_Click(object sender, EventArgs e)
    {
        Button btn = (Button)sender;
        GridViewRow gvr = (GridViewRow)btn.NamingContainer;
        int index = gvr.RowIndex;
        string value = GridView1.Rows[index].Cells[1].Text;
    }
