推荐答案

如果您希望在文本框值为0时禁用链接代码应该有帮助。您可以根据需要更新代码。

If you are looking to have your link disabled while your textbox value is "0" below code should help. You can update the code per your need.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        TextBox textControl = e.Row.FindControl("textbox4") as TextBox;
        LinkButton linkControl = e.Row.FindControl("link1") as LinkButton;

        if(textControl.Text.Equals("0"))
        {
            linkControl.Enabled = false;
        }
        else
        {
            linkControl.Enabled = true;
        }
    }
}
