I want to execute following code on button click but the follwing code executes when I refresh the page as well. I don't want that behaviour. Please help me.
string str = "Are you sure, you want to Approve this Record?";
this.ClientScript.RegisterStartupScript(typeof(Page), "Popup", "ConfirmApproval('" + str + "');", true);
your question in quite unclear. I assumed you use ASP.NET C# , here is the way:
public static class ClientMessageBox
{
public static void Show(string message, Control owner)
{
Page page = (owner as Page) ?? owner.Page;
if (page == null) return;
page.ClientScript.RegisterStartupScript(owner.GetType(),
"ShowMessage", string.Format("<script type='text/javascript'>alert('{0}')</script>",
message));
}
}
then, in your page (remember to reference the class above):
protected void Page_Load(object sender, EventArgs e)
{
ClientMessageBox.Show("Hello World", this);
}
See if it helps in your case.
You should look at putting your alert in to the OnClientClick method of the button.
E.g. (add in your other required attributes and click handler)
<asp:Button ID="ApproveButton" runat="server" CausesValidation="False"
OnClientClick="return confirm('Are you certain you want to approve this record?');" />
If the user clicks OK your normal click code will run but if they cancel the function returns false so the click won't be processed.
Add OnClientClick to your button
<asp:Button OnClientClick="return confirm('Are you sure, you want to Approve this Record?')" runat="server" />
You should be using marto'ss and Chris W's code. If you want a clean HTML Markup, use this.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string script = "javascript:return confirm('Are you certain you want to approve this record?');";
//id of your button
button.Attributes.Add("onclick", script):
}
}
