ASP.NET中Gridview错误的RowIndex [英] RowIndex of Gridview Error in asp.net

问题描述

我正在借助Checkbox实现批量删除功能.但是当我像下面那样拨打ID

I am implementing the bulk delete functionality with the help of Checkbox. But when I call the ID like below

string Id = grdUser.DataKeys[e.RowIndex].Value.ToString();

我收到错误信息

System.EventArgs不包含 RowIndex 的定义.

我不知道为什么会这样.请参阅我的代码以供参考:-

I dont know why it is happening. Please see my code for your reference:-

 protected void btnDelete_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow gvRow in grdUser.Rows)
        {
            CheckBox chkDelete = (CheckBox)grdUser.FindControl("chkDelete");
            if (chkDelete.Checked)
            {
                string Id = grdUser.DataKeys[e.RowIndex].Value.ToString();
            }
        }
    }

让我知道我必须做些什么改变

Do let me know what changes I have to make

推荐答案

您应按照Sandeep的说明添加 gvRow.RowIndex .

You should add the gvRow.RowIndex as stated by Sandeep.

然后，您必须像这样绑定网格视图.

Then you have to bind your gridview somewhat like this.

 protected void btnDelete_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow gvRow in grdUser.Rows)
        {
            if (gvRow.RowType == DataControlRowType.DataRow)
            {
                CheckBox chkDelete = (CheckBox)gvRow.FindControl("chkDelete");
                if (chkDelete.Checked)
                {
                    string Id = grdUser.DataKeys[gvRow.RowIndex].Value.ToString();
                    DeleteRecordByID(Id);
                }
            }
        }

       //Bind your Gridview here
    }

让我知道它是否有效
