有这样一个repeater   我想问的是  当我点ImageButton 的时候怎么  在后台判断我点的按钮是哪一行的 
例：
    protected void Imgbtn_delete_Click1(object sender, ImageClickEventArgs e)
    {
         在这我该怎么获取用户点的是哪行
    }

Answer 1

    protected void protected void rp_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {        if (e.Item.ItemType == ListItemType.Item)
        {
            ImageButton ibtn = e.Row.FindControl("Imgbtn_delete") as ImageButton;
            if (ibtn != null)
            {
                //保存当前ImageButton 所在行的行号
                ibtn.CommandArgument = e.Row.RowIndex.ToString();            }
        
        }
    }
    protected void Imgbtn_delete_Click1(object sender, ImageClickEventArgs e) 
    { 
        string indexStr="";
        ImageButton ibtn = sender as ImageButton;
        if (ibtn != null)
        {
            indexStr=ibtn.CommandArgument;//获得行号
        }       
     }

Answer 2

 protected void protected void rp_ItemDataBound(object sender, RepeaterItemEventArgs e)
在这个事件里，用e表示当前事件的项，不知道说明白没有

Answer 3

你把想要的到的放到ImageButton的CommandArgument属性中，然后再ItemCommand事件中判断，直接用e.CommandArgument就行了。
比如说：
有一个删除按钮，在页面上：
<asp:ImageButton id="..." runat="server" CommandName="Delete" CommandArgument='<%# Eval(数据库中ID字段)%>'>
然后后台：ItemCommand事件中：
if(e.CommandName=="Delete")
{
   //e.CommandArgument就是你所点的行的ID ，就可以写这样的语句了：
  string SQL="delete from 表 where ID='"+e.CommandArgument+"'";
}

Answer 4

sorry ~
    protected void protected void rp_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {        if (e.Item.ItemType == ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem)
        {
            ImageButton ibtn = e.Row.FindControl("Imgbtn_delete") as ImageButton;
            if (ibtn != null)
            {
                //保存当前ImageButton 所在行的行号
                ibtn.CommandArgument = e.Row.RowIndex.ToString();            }
        
        }
    }
    protected void Imgbtn_delete_Click1(object sender, ImageClickEventArgs e) 
    { 
        int rowIndex;
        ImageButton ibtn = sender as ImageButton;
        if (ibtn != null)
        {
            int.TryParse(ibtn.CommandArgument,rowIndex);//获得行号,rowIndex为行号
        }       
     }

Answer 5

忽略AlternatingItem了这回你试试

Answer 6

也可以不用Repeater 的ItemDataBound事件如下:<asp:ImageButton ID="Imgbtn_delete" runat="server" ImageUrl="../logn/btn_03.gif"
 ImageAlign="AbsMiddle" OnClick="Imgbtn_delete_Click1"
CommandArgument ='<%# Container.ItemIndex %>'
/> 
    protected void Imgbtn_delete_Click1(object sender, ImageClickEventArgs e)  
    {  
        int rowIndex; 
        ImageButton ibtn = sender as ImageButton; 
        if (ibtn != null) 
        { 
            int.TryParse(ibtn.CommandArgument,rowIndex);//获得行号,rowIndex为行号 
        }        
     } 

Answer 7

    protected void Imgbtn_delete_Click1(object sender, ImageClickEventArgs e)  
    {  
        int rowIndex; 
        ImageButton ibtn = sender as ImageButton; 
        if (ibtn != null) 
        { 
            int.TryParse(ibtn.CommandArgument,out rowIndex);//获得行号,rowIndex为行号 
        }        
     } 

Answer 8

<asp:ImageButton ID="Imgbtn_delete" runat="server" ImageUrl="../logn/btn_03.gif"
 ImageAlign="AbsMiddle" OnClick="Imgbtn_delete_Click1"
CommandArgument ='<%# Container.ItemIndex %>'
/>   这个行了    
    protected void Imgbtn_delete_Click1(object sender, ImageClickEventArgs e)  
    {  
        int rowIndex; 
        ImageButton ibtn = sender as ImageButton; 
        if (ibtn != null) 
        { 
            int.TryParse(ibtn.CommandArgument,rowIndex);//获得行号,rowIndex为行号 
              这我想获取这行的其他控件值  怎么弄  刚学会用repeater 不熟  谢谢大家
        }        
     } 

Answer 9

    protected void Imgbtn_delete_Click1(object sender, ImageClickEventArgs e)  
    {  
        int itemIndex=0; 
        ImageButton ibtn = sender as ImageButton; 
        if (ibtn != null) 
        { 
            int.TryParse(ibtn.CommandArgument,out itemIndex);//获得行号,itemIndex为行号 
         }
        Literal lit=rptNew.Items[itemIndex].FindControl("lbSend_UserId") as Literal;   
        if(lit!=null)
            Response.Write("<br>" +lit.Text );     
     }
