Web Forms :: How To Use JavaScript Confirm In Page Based On Some Condition

Jul 14, 2012

I want to call javascript confirm function in .aspx.cs page .. I have done it by using RegisterStartUpScript javascript code:

 <html><head runat="server"><script type="text/javascript" language="javascript"> 
function alertMe() {    //alert("Hello");  if(confirm("File with this Name Already Exists, Do you want to Replace it ?")) {
return true;    } else {    return false;       
} }    </script>    </head>    </html>

.aspx.cs code on button click based on some condition:

Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "alertMe();", true);

Now how can I check whether confirm returns true or false, i need to write some code based on confrim's true false return.

Using Javascript Confirm Dialog On A Button Within An UpdatePanel - Posting Back Full Page?

Mar 31, 2011

I basically want to show a dialog box with confirm or cancel options on it.

Confirm should allow the partial postback to take place, cancel should not. I have tried using a trigger and calling __doPostBack() as advised here but it posts back the full page not just the panel.

$('#buttonInUpdatePanel').live('click', function (event) {
event.preventDefault();
var item = this;
var title = 'Confirm';
var msg = 'Please confirm something';
var $dialog = $("<div id='myDialog'></div>")
.html(msg)
.dialog({
modal: true,
buttons: {
"Confirm": function () {
$(this).dialog("close");
__doPostBack('Button1', null); //tried this and .submit() on the button
//return true;
},
"Cancel": function () {
$(this).dialog("close");
//return false;
}
},
title: title
});
});

My UpdatePanel:

<asp:UpdatePanel ID="UpdatePanel2" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:TextBox runat="server" ID="TextBox1" />
<asp:Button
ID="Button1"
Text="Add"
OnClick="AddExtraVehicle_Click"
runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
</Triggers>
</asp:UpdatePanel>

UPDATE:

I have changed the doPostBack to use the button ID now and commented out the return true and false lines. When I click the button it calls the confirmation dialog but when you click on confirm it appears to do nothing. I was expecting a call to the method AddExtraVehicle_Click but the breakpoint didn't trigger.

Web Forms :: Hide Specific Row Cell From GridView Based On Some Condition

Aug 3, 2012

I have a gridview which displays a list of submittted applications with a column that contains an edit link.

<asp:TemplateField HeaderText="Status">
<ItemTemplate>
<asp:LinkButton ID="lnkBtnEdit" runat="server" CommandArgument = '<%# Eval("appID")%>' Text = "Edit" OnClick = "editApp" />
</ItemTemplate>
</asp:TemplateField>

I want to hide the link button if the status (value 1 or 0) of the form is set to 1. Here is the code I am trying to use.

Protected Sub gv1_RowDataBound(sender As Object, e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
'get the cell cell value
Dim status As Integer

[code]....

I think my mistake lies in getting the status value (as it ouputs 0 for every application).
