How to add and delete a prompt box for 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:

1 2 3 4 5 6 7

<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? ') ", As follows:

The following is a reference clip:

1 2 3 4 5 6 7

<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>
