Prompt box for adding and deleting the gridview in ASP. NET

In the gridview, we can directly add a commandfield deletion column to delete a row. However, in order to avoid accidental deletion due to misoperations, the operator is asked to confirm the deletion before deletion.

First, we add a template column to our gridview, as shown below:

The following is a reference clip: <Asp: templatefield headertext = "delete" showheader = "false"> <Itemstyle forecolor = "red"/> <Itemtemplate> <Asp: linkbutton id = "btndelete" runat = "server" causesvalidation = "false" commandname = "delete" TEXT = "delete"> </ASP: linkbutton> </Itemtemplate> </ASP: templatefield>

Next, we add onclientclick = "Return confirm ('Are you sure you want to delete this row? ') ", Visit: http://www.cnnic-qd.cn/it/index.html

The following is a reference clip: <Asp: templatefield headertext = "delete" showheader = "false"> <Itemstyle forecolor = "red"/> <Itemtemplate> <Asp: linkbutton id = "btndelete" runat = "server" causesvalidation = "false" commandname = "delete" TEXT = "delete" onclientclick = "Return confirm ('Are you sure you want to delete this row information? ') "> </ASP: linkbutton> </Itemtemplate> </ASP: templatefield>

When you click Delete, "Are you sure you want to delete it?" is displayed on the client first ?" Dialog Box. Generally, confirm the deletion.
