尝试一下

Try this

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                LinkButton lb = e.Row.FindControl("yourLinkButtonID") as LinkButton;
               string text =  lb.Text; // read
               lb.Text = "some";  // write
            }
        }

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

       onrowdatabound="GridView1_RowDataBound">

访问链接按钮在gridview的itemtemplate内的链接按钮单击事件

access linkbutton in link button click event inside itemtemplate in gridview

假设单击的行的行值不确定，则不确定要尝试访问的值.

一种方法是在ItemTemplate
内为LinkBut​​ton控件添加Click事件.

Not sure what value you are trying to access , assuming Row Values of the Clicked Row.

One way is to add Click event for the LinkButton Control inside the ItemTemplate

protected void lnkBtn_Click(object sender, EventArgs e)
{
    GridViewRow gridrow = (GridViewRow)((LinkButton)sender).NamingContainer;
    // If need to get the value of BoundField use below
    string value = gridrow.Cells[0].Text;// Change index of Cells[0] to get the specific cell 											value
    //Or if trying to access the value of Control inside ItemTemplate then use below Line of Code
	Label lblControl = (Label)gridrow.FindControl("ControlID");
	string value = lblControl.Text;    
}

否则，将CommandArgument和CommandName添加到链接"按钮并使用GridView控件的RowCommand事件. CommandArgument应该与获取所需的值绑定

Or other way is to Add CommandArgument and CommandName to the Link Button and use the RowCommand Event of the GridView Control . The CommandArgument should be bound with the value needed to fetch
like

CommandArgument=''<%# Eval("ID") %>'' and CommandName="lnkClick"

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) 
{    
 if (e.CommandName == "lnkClick")
    {         
      String ID = e.CommandArgument.ToString();      
     }

}
