Question

我想从GridView中删除记录。在此之前要求确认，例如“你确定要删除吗？”

我在GridView中使用了命令字段，

<asp:CommandField HeaderText="Delete" ShowDeleteButton="True" />

我在javascript中写了一个函数

function confirm_Delete()
{
    var r = confirm("Are you sure you want to Remove this Record!");

    if (r == true)
    {
        alert("Record Deleted");
        return true;
    }
    else 
    {
        return false;
    }
}

如何在删除点击时调用此方法。请建议！

Answer 1

使用命令字段无法实现此目的，您必须创建模板字段：

<asp:TemplateField>
        <ItemTemplate>
            <asp:LinkButton ID="lbtnDelete" runat="server" CommandName="Delete" Text="Delete" 
             OnClientClick="javascript:return confirm('Are you sure you want to Remove this Record!');">
            </asp:LinkButton>
        </ItemTemplate>
    </asp:TemplateField>

它的行为方式与您目前使用命令字段的方式相同。

我会做相同@Muhammad告诉你，并且在用于删除我还注册一个脚本示出“记录中删除”消息的服务器端代码，如下所示;

public void MethodForDeletingARecord()
{
    ScriptManager.RegisterStartupScript(this.Page, base.GetType(), "RecordDeletedMessage", "javascript:alert('Record Deleted');", true);
}

Answer 3

我认为你可以为commandfield实现这个目标

假设它是第一列，Found Here

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // reference the Delete LinkButton
        LinkButton db = (LinkButton)e.Row.Cells[0].Controls[0];

        db.OnClientClick = "javascript:return confirm('Are you certain you want to delete?');"
    }
}

Answer 4

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        ((LinkButton)e.Row.Cells[0].Controls[0]).Attributes.Add("onclick", "return Conformation();");
    }
}
