I have a page which includes serveral gridviews, pulling out data from my datasources. At this stage, the parameters are set withing the page, however it will use a querystring at the end of the url. Once the page is loaded, i then have an Email function calling a HTML reader, which basically captures the content of the page and pushes to the body of the email and then emails it out.
The issue i am having is where to place this stagement. I have tried to insert the email function in the Page (load complete) event, but it still seems to send out over 20 emails, which to me, means that the page hasnt finished? loading and is constantly calling the email function.
At this stage, i need this page to load .. i cant think of any other way, i can get the data sent to an email without the interim medium; the page.
I am using asp.net3.5 C# with Jquery

In a button click, I need to be able to hide my ModalPanel and then continue running other code server-side. I currently have it this way:
[Code]....
It hides the panel at the of the event handler because that's when the page posts back. So what can I do to hide the panel and then continue running the rest of the server-side code?
Basically what I'm trying to do is the following:
1. Button_display in my webform simply displays my UpdatePanel via ModalPopupExtender.
2. Button_closePanel_Click will hide my UpdatePanel and then run some server-side code, which would display my UpdateProgress control.
protected void Button_closePanel_Click(object sender, EventArgs e)
I had this problem: I created a WebUserControl that used som Ajax stuff - hence it needed a ScriptManager.
The problem was that I couldn't add it to the WebUserControls html code (the .ascx file) since the WebUserControl sometimes was placed into a parent page that already had a ScriptManager, and I couldn't add a ScriptManagerProxy since the parent page sometimes didn't had a ScriptManager.
Alot of people just use a ScriptManager on the MasterPage, but this fails if: one doesn't use a MasterPage or one uses iFrames etc. that uses stand alone aspx pages, like Thickbox might do...
Here's the solution:
in the WebUserControls code behind (.cs file), put this:
protected override void OnInit(EventArgs e)
I have a webusercontrol with a flash control. I want to assign the movieurl from codebehind when the webusercontrol is registered in a new page.
<uc1:PopVideo
ID="PopVideo1"
runat="server"
/>
inside this webusercontrol I have a flash movie player that I can assign the movieurl in codebehind on the webusercontrol. The problem is that I need to assign the value from the new page the control is registered under. How can I access the flash control from the new page and assign the value?
I have an MasterPage with
<asp:ScriptManager id="s" runat="server" />
<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">

But i get an error that the page only can include one ScripManager

How do you call a codebehind/class method from a gridview in an aspx page? Also, I need to pass the value of databound column to that method. Is this possible?
Something like this:
<asp:BoundField DataField="Precision" />
<asp:BoundField DataField="MyNumber" DataFormatString="FormatHelper.Format(MyNumber, Precision)" />
Hosting page:
protected void Page_Load(object sender, EventArgs e)
{
LoadMyControl(Parameters); //Do it every page load to preserve it's state
}
protected void LoadMyControl(string parameters)
{
plchld.Controls.Clear();
Control userControl = LoadControl("TheUserControl.ascx");
userControl.ID = "userControl1";
plchld.Controls.Add(userControl);
}
Now inside this control, when a button is clicked I want to update ,let's say a Label on the hosting page.
What is the best way to do it? Custom event?
I have user control that inherits a base control class and these user controls are loaded using the LoadControl method, I can't seem to figure out how to raise events from user controls to the page that are dynamically loaded this way. Here is the delegate and event in the base user control class.
public delegate void SomeChangeEventHandler(object sender
, SomeChangeEventArgs e);
public event SomeChangeEventHandler SomeChangeEvent;
public virtual void OnSomeChanged(SomeChangeEventArgs e)
{
if (SomeChangeEvent != null)
{
SomeChangeEvent(this, e);
}
}
I have a page that contains a custom tab control. When you click different tabs, it does a an ajax callback. During that ajax call, the code dynamically loads a different control based on which tab was clicked, then adds it to the appropriate tab. So basically I have some code that does a switch statement, uses LoadControl(), then adds the control in.
The issue I'm having is that none of the javascript within each of those controls that gets loaded is getting registered on the page. Based on this thread:
[URL]
I thought I just had to switch from using Page.ClientScript.RegisterClientScriptBlock to ScriptManager.RegisterClientScriptBlock. I did that, but still nothing. Am I misunderstanding something about the ScriptManager? I want the javascript to be registered from within the dynamically loaded control, which happens to be loaded during an AJAX call.
OK, this feels like a question that should be easy to answer, but as with so much mixing of asp.net and jQuery, it's a bit of a nightmare.
What I want to do is be fading a div in and out at various times during the client's viewing of my asp.net page; I fade it out using jQuery's fadeTo() before triggering an UpdatePanel update (to indicate that the data there is not fresh) and I want to fade it in again once the UpdatePanel has been updated. I've gotten as far as updating the UpdatePanel in the codebehind, and this results in the div's content changing... but how do I fade the div back in again?
The way I see it, there are 2 ways; register an event handler on page load to detect when the div's content has been changed and fade it back in, or call a function from the asp.net codebehind when I've updated the div to fade it back in.
In the first case, there doesn't seem to be any event triggered by the div's content changing, so I can't seem to do that. If anyone knows how I could get a client event to trigger when I update the div, that would be a nice solution.
In the second case, I thought that this was what ClientScriptManager was for, but it doesn't quite do what I want. I want to be able to register a particular Javascript function with ClientScriptManager and then tell ClientScriptManager to execute it in the client, from my codebehind. You can't seem to do that. ClientScriptManager.RegisterClientScriptBlock() simply inserts some <script> into the HTML output, rather than calling a function. Presumably this would work if I kept registering things like:
<script>fadeBackIn();</script>
because the Javascript would be immediately evaluated and run, but this feels messy, and that feeling is intensified by the fact that I'd have to keep randomly generating a new unique value for the key argument of ClientScriptManager.RegisterClientScriptBlock(), because it's specifically designed to stop this kind of repeated code. However, I'm struggling to see an alternative.
I'd really like something along the lines of:
ClientScriptManager.RegisterClientScriptFunction("fadeBackIn", "function fadeBackIn(){ ... }");
ClientScriptManager.ExecuteClientScriptFunction("fadeBackIn");
In a page , when I click a button 'showDialog' I am loading the user control dynamically in a dialog. I am linking to the event in the user control as explained below. The parent page is not receiving this event.
Button_Click(){
UseControl1 gc = dlg.LoadContent(:UserControl1.csx);
gc.CausePostback += new EventHandler(execute_CausePostback());}
execute_CausePostback(){
In UserControl class after clicking the submit button
Submit_Click(){
saveRecord();
raise event CausePostBack();
I'm developing an ASP.NET application with C# and Ajax.I have a page that holds user controls loaded dynamically. I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically.Now I use Session to pass these values, but I think I can use another way; something like VIEWSTATE or hidden input.What do you recommend me?The fact that I load the controls dynamically is important because controls are loaded on every postback, and I can't store any value on controls.
View 9 Replies I have a page that loads a usercontrol dynamically. Depended on the user's actions, this control may be unloaded in Page_PreRender and a different control may be loaded instead. I am attempting to use the solution outlined by Mark DotNet Evans in this post:
http://forums.asp.net/p/1491790/3814320.aspx
This all works great, except if the user clicks the refresh button in the browser just after the change of usercontrol. Then, I get an error
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. ...
I assume the error is caused by the browser re-posting the request with the old viewstate that matched the control tree when the page was loaded, but no longer does. How can I prevent getting an error when the user reloads the page?
I'm attempting to load DropDownLists from the C# codebehind as the FormView switches modes to Edit and displays the EditItemTemplate. I present the data in a FormView ItemTemplate using text boxes. When the user selects Edit, I have been attempting to load the EditItemTemplate dropdownlists by creating a dataset and binding it to the control, without success.
I've successfully loaded them in previous projects from within the .aspx code using <asp:ListItem> and within the C# code behind using Control.Items.Add(new ListItem), which are essentially the same thing of course . This project is different in that I want to get the data from a stored procedure on a MSSQL server.
In my latest attempt, I can see the data in the datasets. I'm getting "Error connecting to database.'eitRace' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value"
I include the code below. If someone could point me to an example I would be greatful. There has to be an elegant way of accomplishing this.

Have a GridView in an UpdatePanel, all works fine. Click the Submit() button which updates the database on postback, then the GridView is bound in code and I register an alert:
ScriptManager.RegisterStartupScript(this.UpdatePanel1, typeof(string), "dopopup", "alert('Operation successful!');", true);
Calling UpdatePanel1.Update() causes the popup to appear. All fine but what I am noticing is that the alert occurs just before the page has fully updated and is causing a few minor layout issues that are resolved when the alert button is closed (by clicking OK). Is there a way to generate an alert after a full UpdatePanel refresh, so something like:
ScriptManager.RegisterFullyLoadedScript(this.UpdatePanel1, typeof(string), "dopopup", "alert('Operation successful!');", true);
I tried a simple wait() in the code like this:
ScriptManager.RegisterStartupScript(this.UpdatePanel1, typeof(string), "dopopup", "wait(100);alert('Operation successful!');", true);
But this didn't work.

I want to set up menu item links such that the tab index is sent in the query string parameter. I tried setting the ActiveTabIndex in the Page_Load event and that doesn't change it at all. I tried using the javascript and I think because this tabcontainer is contained in a UpdatePanel's ContentTemplate so that javascript is not able to find it? How can I do this?
<script type="text/javascript">
// function SetInitalTabChanged() {
// var leaderTabs = $get('<%=TabLeadershipMain.ClientID%>');
// leaderTabs = leaderTabs.control; //
// leaderTabs.set_activeTabIndex(0);
// }
function SetInitalTabChanged() {
// $('<%=TabLeadershipMain.ClientID%>').set_activeTabIndex(0);
var container = $find('TabLeadershipMain');
container.set_activeTabIndex(0);
}
With javascript above (both) I would get the error below
Microsot runtime jscript error:Object doesn't support this property or method
Or if use the commented out function it will return leaderTabs = null

I am using jquery ajax method to get data from a web method and present data using DOM(similar to that of google search results).B'coz the data returned from the web method is huge I want to paginate the results.For that I need to create buttons corresponding to the page numbers based on the no. of records the web method retrieves from the database.So I have taken a div on the page.In the web method ,as soon as I can find the number of records obtained from the database,I want to create the buttons and add to this div and display 10 records per page.As far as I know, it is not possible to access anything that is placed on the asp.net page from Web method.In that case how do I paginate the results?
