you can take a help of Javascript.
use Confirm() function. here is example

JavaScript

function askConfirm()
{
  if(confirm("are you sure"))
    alert("you clicked Yes")
  else
    {
      alert("you clicked No") 
      return false;
    }
}

add this function on your submit button click.

"return false" will cancel your execution.

could you please let me know this in vb.net code

Solution 4

Insted of msgbox use confirm from javascript.
it has two buttons "ok" and "cancel".

msgbox will execute on the server while confirm executes on client.
you can code for confirm like this:

C#

if(confirm("Are you sure to reload data?")){
    grid.reload();
}else{
    //to do nothing
}

add this property to your button

OnClientClick="return confirm('Are you sure you want to Proceed ?');"

like this

<asp:button id="btnDelete" runat="server" onclick="btnDelete_Click" onclientclick="return confirm('Are you sure you want to Proceed ?');"  />

In button can I add multiple functions in OnclientClick()

Solution 7

Try this.

ASP.NET

<asp:button id="btn" runat="server" xmlns:asp="#unknown">OnClientClick="javascript:return confirm('Are you sure you want to delete this user?')" /></asp:button>

Solution 10

you can use on clientClick Property of Button
for example

<asp:button id="btnSubmit" runat="Server" text="Submit" onclientclick="return askConfirm()" xmlns:asp="#unknown">

and for back end you are use following code for it

if(result>0)
{
string myscript = "alert ('message');";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "MyScript", myscript, true);
return false;
}

I m getting an error "Name result unknown error" in code
what should I do

Solution 11

Try This:

1) Right Click on Solution Explorer & Add reference the "System.windows.Forms";

2) Now create a button in Default.aspx.

3) Double click on that button, Default.aspx.cs will open.

4) In that first of all add a namespace at the top "System.windows.Forms".

5) Now in button1 coding block write code,

Collapse | Copy Code
protected void Button1_Click(object sender, EventArgs e)
{
MessageBox.Show("yes.", "AIOOB", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Question);

}
6) Now it is done.

but if the user clicks YES then i need to execute functions that are coded with VB.net in the code behind page.
so how do i get if yes, then execute the codebehind code?

thanks

koolprasad2003 10-Oct-11 7:48am

Dear friend, code behind get automatically called after Javascript execute.
if you clicked YES your code behind will called automatically.
paste the code and see the output.

I have doubt.
If i press the Submit button in one Form,i want to display one PopUpBox with
Yes or No Buttons.In that Box If i Press YesButton again
one more popUpBox i want to display with One Label along with TextBox and Save Button.
First PopUpBox i did.But second popUp Box with label,TextBox and Save button how to do?
Plz provide solution to me .

koolprasad2003 9-Nov-12 23:57pm

With the Help of Javascript you can not easily put label, textbox and button. Better to Design a from as per your requirement and call it as POPUP with the help of Javascript.

Best luck.
