如何在asp.net中获得确认弹出窗口

Question

Inside the grid I have a delete button inside a grid and have a code behind to perform the delete.

<asp:TemplateField HeaderText="Edit Controls" ItemStyle-Width="15%">
 <ItemTemplate>
   <asp:LinkButton ID="Lnk_Delete" ToolTip="Delete Message" 
   CommandArgument='<%#Eval("MsgID") %>' CommandName="Delete" runat="server"> 
   <img id="Img1" src="Styles/Images/Delete.jpg" runat="server"  /></asp:LinkButton>
 </ItemTemplate>
</asp:TemplateField> 

 protected void Grid_Messagetable_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {

    }

Everything works fine how to get a confirm pop up before the delete is performed.

Answer 1

You could use the OnClientClick property as shown in the following article :

<asp:LinkButton 
    ID="Lnk_Delete" 
    runat="server"
    ToolTip="Delete Message" 
    CommandArgument='<%#Eval("MsgID") %>' 
    CommandName="Delete" 
    OnClientClick="return confirm('Are you sure you want to delete this record?');"> 
    <img id="Img1" src="Styles/Images/Delete.jpg" runat="server"  />
</asp:LinkButton>

Answer 2

onClientClick="return confirm('Are you sure you want to delete?')";

Answer 3

尝试添加

OnClientClick="return confirm('Do you want Delete?');"
