推荐答案

取一个隐藏字段并放入除了复选框，并为其分配rowindex.

take one hiddenfield and put besides checkbox and assign rowindex to it.

<asp:checkbox id="yourcheckbox/" xmlns:asp="#unknown"><asp:hiddenfield runat="server" id="hidRowIndex" value="<%# Container.DataItemIndex %>" /></asp:checkbox>

并使用
进行检索

and retrieve using

protected void btnLink_Click(object sender, EventArgs e)        {            foreach (GridViewRow row in gvAllocated.Rows)            {                if (((CheckBox)row.FindControl("chkLink")).Checked)                {
                        int index = (((HiddenField)row.FindControl("hidRowIndex")).Value;

                       // here you can acess your other values using rowidnex
               }            }        }

尝试以下方法:

Try this one:

CheckBox chk;
int ID = 0;

foreach(GridViewRow row in GridView1.Rows)
{
   chk = (CheckBox)row.Cells[0].FindControl("chkboxid"); //chkboxid is the ID of the checkbox control in asp.net inside template field
   if(chk.Selected == true)
   {
      ID = Convert.ToInt32(row.Cells[1].Text);
   }
}

其中Cells [0]是复选框，而Cells [1]是所选项目的ID.
然后使用ID作为查询的输入参数来更新...

如果这解决了您的问题，请标记为答案

Wherein Cells[0] is the checkbox and Cells[1] is the ID of the selected item.
Then use ID as an input parameter for your query to update...
