大家好，

以下是ASPX中的代码

Hi All,

protected void btnApprove_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow grd in GRVLeaveRequest.Rows)
        {
/*Here I have to find out datakey value and each cells value*/

    }

推荐答案

要查找该行的单元格值，您需要先找到按钮的容器行.

参见此 [ ^ ]肯定会为您提供帮助.

[更新]

现在，您从链接的文章中获得了GridViewRow(grdRow)的对象.

您可以像下面那样进一步调查，以找到有关Button click事件的数据键

for finding cell values of that row you need to find container row of button first.

See THIS[^] will surely help you.

[update]

As you now got object of GridViewRow(grdRow) from linked article.

you could further investigate like below to find datakey on Button click event

GridViewName.DataKeys[grdRow.RowIndex].Value.toString();

如果每一行都存在按钮，则不需要遍历每一行.

you do not need to loop through each row if button is present for every row.

foreach(GridView1.Rows中的GridViewRow行)
{
int _dkname = Convert.ToInt32(GridView1.DataKeys [row.RowIndex] .Value);


}

foreach (GridViewRow row in GridView1.Rows)
{
int _dkname = Convert.ToInt32(GridView1.DataKeys[row.RowIndex].Value);


}
