• e.Row.FindControl("hlPlus") is used to find the HyperLink control with the ID "hlPlus" in the current row.

Answer the question

Here is an example of how to use the FindControl method to find a specific control:

// 获取当前正在处理的行
GridViewRow row = grvYourOpportunities.Rows[e.RowIndex];

// 查找 HyperLink 控件
HyperLink hlPlus = row.FindControl("hlPlus") as HyperLink;

// 如果控件存在，执行任何必要的操作
if (hlPlus != null)
{
    // 将 hlPlus 的 ImageUrl 设置为 "plus.gif"
    hlPlus.ImageUrl = "plus.gif";

    // 将 hlPlus 的可见性设置为 true
