在确认消息后删除gridview中的行

本文关键字：gridview 删除 确认 消息 | 更新日期: 2023-09-27 18:18:51

以前为了删除我的记录，我会使用双击，但是当涉及到平板电脑或手机时，双击将识别为放大/缩小，因此我更改为onclick确认消息，这里出现了问题，我该如何在用户按下ok后删除它?

p/S:我没有使用按钮，而是通过选择行来删除数据

当前onclick代码

e.Row.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this order? ');");

上一页双击删除代码

//e.Row.Attributes.Add("ondblclick", "__doPostBack('CView','Select$" + e.Row.RowIndex + "');");

它的完整代码

protected void CView_RowDataBound(Object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#cccccc'");
        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
        e.Row.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this order?');");
        //e.Row.Attributes.Add("ondblclick", "__doPostBack('CView','Select$" + e.Row.RowIndex + "');");
    }
}

我还在用谷歌搜索答案。如果有人问了同样的问题，请把链接分享给我。谢谢你

在确认消息后删除gridview中的行

如果下面一行从gridview中删除行

e.Row.Attributes.Add("ondblclick", "__doPostBack('CView','Select$" + e.Row.RowIndex + "');");

并且你想在确认时调用上述功能，那么你可以做以下更改:

if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#cccccc'");
        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
        e.Row.Attributes.Add("onclick", "var vconfirm = confirm('Are you sure you want to delete this order?'); if (vconfirm){ __doPostBack('CView','Select$" + e.Row.RowIndex + "');}");          
    }

尝试为按钮分配aspx代码中的OnclientClick，如下所示

<asp:TemplateField>
      <ItemTemplate>
            <asp:Button ID="deletebtn" runat="server" CommandName="Delete" 
             Text="Delete" OnClientClick="return confirm('Are you sure you want to delete this order? ');" />
      </ItemTemplate>
</asp:TemplateField>

试试下面的代码

<asp:GridView ID="GridView1" runat="server" OnRowDeleting="OnRowDeleting" AutoGenerateColumns = "false" OnRowDataBound = "OnRowDataBound">
<Columns>
    <asp:BoundField DataField="..columnname.." HeaderText="...." />
    <asp:BoundField DataField="..columname.." HeaderText="...." />
    <asp:CommandField ShowDeleteButton="True" ButtonType="Button" />
</Columns>

Then on Row DataBound

   protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
    {
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
    string item = e.Row.Cells[0].Text;
    foreach (Button button in e.Row.Cells[2].Controls.OfType<Button>())
    {
        if (button.CommandName == "Delete")
        {
            button.Attributes["onclick"] = "if(!confirm('Do you want to delete " + item + "?')){ return false; };";
        }
    }
    }
    }

然后删除

 protected void OnRowDeleting(object sender, GridViewDeleteEventArgs e)
 {
     // delete code
int index = Convert.ToInt32(e.RowIndex);
DataTable dt = ViewState["dt"] as DataTable;
dt.Rows[index].Delete();
ViewState["dt"] = dt;
BindGrid();
 }
