推荐答案

使用 RowDataBound 事件 GridView 。

添加 runat =server到 img 标签，否则将其更改为 asp：Image 。



执行以下操作。

Use RowDataBound Event of GridView.
Add runat="server" to the img Tag, else change it to asp:Image.

Do something like below.

protected void YourGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{   
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // Find Image control.
        Image imgEdit = (Image)e.Row.FindControl("imgedit");
        
        if (someLogic)
        { 
            imgEdit.Visible = true; 
        }
        else 
        { 
            imgEdit.Visible = false; 
        }
    }
}
