I have a user control that is supposed to call a javascript function at startup, where exactly should I put my javascript function and how should I call it when the Control Is shown to the user.
View 13 RepliesI'm trying to find a hook / way to run some initial code to wire up a bunch of things before a service is called.
View 2 RepliesI have one user control which has 2 gridview first grid has columns (GroupName, Description, chkRemove checkbox) another gridview has columns (GroupName, Description, chkAdd), apart from that i dont have any code on .cs file of usercontrol.
I want to call same user control on 4 aspx pages and datagrid binding, sorting, paging and search functionality i want to do on respective aspx.cs pages not on user control where i am calling this uercontrol because for every aspx page field name is same but when i am binding the data to the grid that logic is different.
For first aspx page i called my usercontrol like this and everything is working fine: -

I have an aspx page with multiple modal popups. These modal popups are trigger in the page behind code using .Show() and .Hide().
This is what I have in the .aspx page for the particular modal popup under discussion:
[Code]....
The example below demonstrates the type of calls I am making to the modal popup extenders. Basically using the Datalist item command, the datalist commands are responsible for triggering my modal popups.
[Code]....
They all work fine after postbacks except the "activityReport" case (the last one). The only difference with this modal popup is that it contains a user control and all the postbacks are happening in the user control. So the problem is that in the last case whenever a postback happens in the user control then the modal popup is close.
1. If I separate the modal popup and place it in a page all by itself and trigger it to .Show() through a button click in the page behind code then the modal popup doesn't close. See below example.
[Code]....
2. The button click event in the test page looks as follow:

I have a GridView of thumbnail photos within an UpdatePanel, with clickable icons in each row which each load a User Control containing a small Google Map into the relevant row. The idea is that the user can geotag (by clicking on the map) any photo in the GridView.
In the map User Control, there is some Javascript initialising the map:
function initializeMap() {
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById('Map'), {size: new
GSize(336, 200)});
// set the map controls, set the centre, etc.
}
}
Problem is: I don't know how to call the initializeMap() method. Because it's dynamically added to the page, any attempt to link it to the calling button by "onClientClick=initializeMap()" for example, gives a JS error, saying the method isn't defined.
I've tried
ClientScript.RegisterStartupScript(this.GetType(), "initializeMap", "<script type="text/javascript">alert('Here'); initializeMap();</script>");
but I don't think I'm on the right track with that one either.

How do I set some batch file ,that I have wrote ,to be executed right when each user logs-in?
(Include it in the statup functions to be executed).
I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.

I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
[Code]....
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
I went to the Code Plex site and down load the latest toolkit. Then followed the instructions on how to set up the toolkit to the letter. When I first loaded the toolkit everything worked. But now every time I start up my computer and start VS all the AJAX controls I have on any page has the green squiggly line underneath it and the error says:Element <AJAX Control Name> is not a known element. This can occur if there is a compilation error in the web site, or the webconfig file is missing.The only thing I can do is delete the Ajax Toolkit tab then add the tab again and then "Choose Items..." and load the Ajax controls again. Then I have to add an AJAX control from the toolkit to any webpage. Once that is done all the green squiggly lines go away and I can continue.This is becoming an incredible pain.

Is there any way for one user control to raise an event that is handled by another user control without going through the page? I am using Umbraco and do not have access to the page object.
--Edit--
Umbraco has the idea of Macro's (user controls) that it loads into pages. I can't access the page directly as this is part of the framework.
There is a publish subscribe (pubsub) pattern that I know would fit my needs well (2 user controls that need to talk to each other) but am unsure how to hook it up in ASP.Net without the page object.
I have a webdayview control (Infragistics proprietary ASP.net control) on my page. On the aspx source I've inserted some javascript (webdayview_click - clientside click event) that calls a webmethod in the codebehind. This seems to work fine, but when I
insert this webdayview control into a user control and move the corresponding javascript into the aspx of the user control, it doesn't work. I can't even insert a breakpoint into the javascript function to debug it. Is there a way to make it work? I want to enable the click event of the webdayview control so that when I click on it, the javascript function calls the webmethod. Here's my code (remember it is inside a user control):
[code]...
I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)
I have a database table with a list of locations. I need to generate addresses for each of these automatically when a user provides a minor amount of input.
The address is a 12 digit numerical witch looks like this;
702200100105
Broken down as follows;
7 is static
022 is selectable as 022 or 076
001 would be a routing reference automatically incrementing
001 would begin the list of address range
05 is static
The user would need to select the list of locations and then provide either the 022 or 076. The background programming would need to build the list of addresses and then finally update the database table with this information.
I have a database with tons of SP. Is there a way to grant a new user access to all SP so the user can execute then?If the SP inserts data in a table do I have to grant the the user that executes the SP so he/she is allowed to insert data

View 3 RepliesI have a problem with button event in web user control
First i have an aspx like this:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="AddTest.aspx.cs" Inherits="AddTest" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<script src="js/jquery-1.4.2.min.js" type="text/javascript"></script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div id="divContent" runat="server">
</div>
</form>
</body>
</html>
As you see i have a ScriptManager to do with ASP.NET AJAX, a div with ID divContent to load controls, then in code behind:
protected void Page_Load(object sender, EventArgs e)
{
divContent.Controls.Add(LoadControl("~/thitai/addtest.ascx"));
}
I add addtest.ascx to divContent as you see, and this is the code of addtest.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="addtest.ascx.cs" Inherits="thitai.addtest" %>
<asp:UpdatePanel ID="updatePanel" runat="server" ClientIDMode="Static">
<ContentTemplate>
<input type="button" value="Load text" onclick="updPanel('text');return false;" />
<input type="button" value="Load image" onclick="updPanel('image');return false;" />
<asp:HiddenField ID="hftype" runat="server" ClientIDMode="Static" />
<div>
<asp:PlaceHolder ID="plhControl" runat="server"></asp:PlaceHolder>
</div>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
<script type="text/javascript">
function updPanel(type) {
$("#hftype").val(type);
__doPostBack("updatePanel", "");
}
</script>
Each time i click on Load text button, i change the value of hfType (hidden field) then do postback to server using UpdatePanel, then this is code behind
protected override void OnPreRender(EventArgs e)
{
string type = hftype.Value;
switch (type)
{
case "text":
plhControl.Controls.Add(LoadControl("~/thitai/test/text.ascx"));
break;
case "image":
plhControl.Controls.Add(LoadControl("~/thitai/test/image.ascx"));
break;
default:
plhControl.Controls.Add(LoadControl("~/thitai/test/text.ascx"));
break;
}
base.OnPreRender(e);
}
This is the code of text.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="text.ascx.cs" Inherits="thitai.test.text" %>
<%@ Register Assembly="Support" Namespace="Support.CustomEditor" TagPrefix="Editor" %>
<Editor:CustomEditor ID="edNoidung" runat="server" NoScript="True" Content=""
Height="500" ActiveMode="Design" NoUnicode="True" InitialCleanUp="False" />
<div>
<asp:Button ID="Button1" runat="server" Text="Show HTML"
onclick="Button1_Click" />
</div>
<div id="showHtml" runat="server"></div>
And code behind of text.ascx
protected void Button1_Click(object sender, EventArgs e)
{
showHtml.InnerHtml = edNoidung.Content;
}
The problem is: when i click to button1, the page do a postback using AJAX but event Button1_Click DOES NOT FIRE!
In aspx page, I am using a user control which contains a button. I need to hide the button(which is in user control) when a checkbox(in aspx) is clikced. I have a postback for checkbox.

Is it possible to access the button using FindControl and disable it? Which event can be used for it?
View 3 RepliesCurrently i'm saving pictures to our sql server db. A user can go to a clients info page and click an id card image to open a new tab or window and see the picture saved for that client.
What I would like to do is when a client info page opens a small version (thumnail) of the picture to display and let the user click the thumbnail to open a bigger icture in a popup window.
I'm going nuts here.. This is what i like to do: When i click my serverbutton i want a fade message to show and then execute as usual all the servercode (db insert and more) i have in my button_click event in code behind. The fade effect works, but the servercode never executes. I don't know how many guides i have tried but it seems impossible to achieve this. I just want to fire the the code in my click_event. I really hope someone of you can point me in the right direction.
This is my fade code:

View 3 RepliesI thought that Page_Load events executed every time a page was loaded not just the first time. Am I wrong on this?
I have a Page_Load event that writes text to a label to display on the screen:
Output.Text &= "Welcome to my Website <br />" (Output being the ID of a Label control)
I also have an On_Click event for a button to display the same information:
Output.Text &= "Welcome to my Website <br />"
After clicking the button, I expected to see the output twice. Once for the page being reloaded and once for the click event. I thought that Page_Load events executed every time a page was loaded not just the first time.
I am loading in a user control on page load and events are never firing. The user control loads fine with the correct information. it contains two dropdowns and an
calendar control. The dropdown selection changed event is never fired. I am not sure if there is something wrong while control is being rendered.
