问题描述

你好，



如何在网格视图行数据绑定事件中找到图像控件

推荐答案

请查看 Control.FindControl 方法。 此处 [ ^ ]是MSDN链接。



一个示例用法是：

Please look at the Control.FindControl Method. Here[^] is the MSDN link.

An example usage will be:

Label myLabel = (Label)myGridView.Rows[myGridView.SelectedIndex].Cells[2].FindControl("myLabel"); 

祝你好运，

Good luck,

试试这个

Try this

protected void gridview_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        (Image) img=((Image)e.Row.FindControl("Image control id"));
    }
}

例如你有Gridview1有3列picturid，picturname，picture。

E.g. you have Gridview1 with 3 columns picturid,picturname,picture.

<asp:templatefield xmlns:asp="#unknown">
      <itemtemplate>/*3rd column of gridview*/
        <asp:image id="Image1" imageurl="~/images/ab.jpg" runat="server" />
      </itemtemplate>
    </asp:templatefield>

gridview的RowDataBound事件：

RowDataBound event of your gridview:

protected Gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
     if (e.Row.RowType == DataControlRowType.DataRow)
     {
            Image desired_image = (Image)e.Row.Cells[2].FindControl("Image1 ");
     }
}
