dynamic javascript of an .ascx control not updating on client upon async postback

Posted By:      Posted Date: October 12, 2010    Points: 0   Category :ASP.Net
 

I have a confusing state issue. I found a way around it, but I would like to know why this is happening. First of all, I am using .NET 3.5 and that can't change right now (an easy fix may be the fixed ID capabilities of .NET 4.0).

Type csType = this.GetType();
ClientScriptManager cs = Page.ClientScript;
string jScriptBlockName = "SignUpSignInNameAvailabilityScript";
if (!cs.IsClientScriptBlockRegistered(csType, jScriptBlockName))
{   //NOTE: verified code always enters this
    StringBuilder cstext2 = new StringBuilder();
    cstext2.Append("function GetSignUpSignInNameAvailabilityMessage() { var id = '"
          + CreateUserWizardStep1.ContentTemplateContainer.FindControl("iSignUpSignInNameAvailabilityMessage").ClientID
          + "'; alert(id); return id; }");
    cs.RegisterClientScriptBlock(csType, jScriptBlockName, cstext2.ToString(), true);
}

This code is in Page_Load of an ascx. The same control is drawn on two separate postbacks of an UpdatePanel in different places of the page thus giving them different client IDs. The code works correctly on the first refresh of web browser; but after UpdatePanel

Client Javascript runs, but then page errors out when clicking on a control that uses postback

  
Using this script on a button click <script language="javascript"> function printdiv(printpage) { var headstr = "<html><head><title></title></head><body>"; var footstr = "</body>"; var newstr = document.all.item(printpage).innerHTML; var oldstr = document.body.innerHTML; document.body.innerHTML = headstr + newstr + footstr; window.print(); document.body.innerHTML = oldstr; return false; } </script> After it is done, I can't click on my calendar control.  I was hoping to add somethign that would force a refresh in the script, but nothing I do works. Any thoughts?  Thanks! 

ASCX Control for Javascript

  

Hello.

I have created an .ascx control that contains javascript functions.  I have created a Feature that allows me to deploy it to a site collection.

How do I now include that in any page in SharePoint?

I have tried the following:

<asp:Content ID="JScript1" ContentPlaceHolderID="????????" runat="server">
<MyWorkStat:MyWorkStat ID="JScript2" runat="server">
</asp:Content>

 

but I don't know what the ContentPlaceHolderID should be set to.

 

Really I looking for a way to easily inject javascript into SharePoint pages using Features that I can turn on and off. e.g. pieces of javascript that call jQuery functions.

 

Is there a way?

How to access child(.ascx) page control from parent page(.aspx) javascript

  

I have functionality to select All check boxes on grid rows.

Child User control is having grid with checkbox to select all rows of grid. I want to select individual cell html from each row when I select all rows when checkbox 'select all' is clicked and place it into textbox which is in Parent page.

This textbox can only be in parent page.

So i need to call child(.ascx) page control from parent page(.aspx) using javascript as follows.

function CheckUncheckChildren(event)
    {
        document
        debugger;
        var childChkBoxes = document.getElementById('<%=gvUserDetails.ClientID %>').getElementsByTagName("input");
        var childChkBoxCount = childChkBoxes.length;
        var evtelem = (isIE())?event.srcElement:event.currentTarget;
        if(evtelem.checked == true)
        {
            for(var i = 0; i<childChkBoxCount; i++)
            {   
    &nbs

Adding Dynamic Rows in ASP.NET GridView Control with TextBoxes and with Delete functionality

  
In my previous examples, I have demonstrated on how to add dynamic rows in GridView control with TextBoxes and how to save the values into the database. Now, seems that most of the developers are asking if how to add a delete functionality with it. So in this example, I'm going to show on how to delete a certain row in the dynamic GridView with TextBoxes.

Content page control passes as argument to javascript function

  

Here is the content page:

********************************************************************

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="JavaDynamicCopyValue.aspx.cs" Inherits="JavaDynamicCopyValue" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
 <script type="text/javascript" >
 function copyValue(input, output )
{
   ouput.value = input.value;
   return true;
}
 </script>
 <asp:TextBox ID="txt1" runat="server" onchange="copyValue(this,document.getElementById('<%=txt2.ClientID%>'))"></asp:TextBox>
    <br />
    <br />
    <asp:TextBox ID="txt2" runat="server"></asp:TextBox>
</asp:Content>

********************************************************************

I got a javascript run time error says output is undefined. if I view source of the page, the txt1 markup became:

<input name="ctl00$ContentPlaceHol

"Type ASP.x is not defined" error for dynamic user control when publishing updateable

  

I have a user control (ContainerCtrl) which programmatically instantiates another user control (SimpleCtrl) in OnLoad. It builds and runs fine, but when I publish it I get the error "error BC30002: Type 'ASP.SimpleCtrl' is not defined." (If I publish without the "updateable" option there's no error, but I need the site to be updateable.)

I assume this has to do with the particulars of how the assembly(ies) are built for the different compiler options. My question is, how can I get it to work properly for "updateable" publishing?

VS 2008 / .NET 3.5 sp1

The code follows (web.config is the default from Visual Studio).

Many thanks, Dave

Web-Aware Apps: Build Hyperlinks into Your Client App with the Windows Forms LinkLabel Control

  

LinkLabels are Windows Forms controls that enable a user to hyperlink to a URL that points to either the Web or the local directory system. While the SDK documentation discusses the control, it does not demonstrate how linking is accomplished, nor does it outline the power and flexibility the control provides. This article fills those gaps, showing how to link using the LinkLabel control. It also shows the flexibility of this control for the programmer using the .NET Framework. In addition, the author covers the large number of properties that allow you to customize your controls and accurately place them. Their built-in behaviors are also discussed, along with their use in both Visual Basic .NET and C#.

But im getting the error:

HierarchicalDataBoundControl only accepts data sources that implement IHierarchicalDataSource or IHierarchicalEnumerable.

Dynamically load user control without postback

  

Hi all,

I need urgent help. (c#coding)

In my base page, I have a dropdownlist control which loads different usercontrols on selectedindexchanged event.

While loading these usercontrols, my page postbacks all the page. I used updatepanel but again same problem.

Is there any way to load controls without postback? I Really need help as soon as possible.

Here is my code:

protected void Page_Init(object sender, EventArgs e)
    {
        if (Session["control"] != null)
        {
            string c = Session["control"].ToString();
            if (c == "1")
            {
                iuc = (IlkogretimUC)LoadControl("~/Controls/Ilkogretim.ascx");
                dl.SelectedValue = Session["control"].ToString();
                ph.Controls.Add(iuc);
                //UpdatePanel2.ContentTemplateContainer.Controls.Add(iuc);
            }
            else if (c == "2")
            {
                luc = (LiseUC)LoadControl("~/Controls/LiseUC.ascx");
                dl.SelectedValue = Session["control"].ToString();
                ph.Controls.Add(luc);
            }
            else if (c == "3")
            {
                youc = (YuksekokulUC)LoadControl("~/Controls/Yuksekokul.ascx");

Stored Procedures & SqlDataAdapter not updating a calendar control

  

Hi all,

I have a database linked to a calendar. I had a peice of code that retrieved dates from a database and populated the calendar. I wanted to tidy up my code using stored procedures (they seem neater & i assume there's a benefit somewhere). so i came up with this, however it's not working. The calendar displays, but it's not being populated with the database entries. The SqlCommand & SqlParameter I have working elsewhere in my code; as with the SqlDataAdapter (which also worked before i tried to conver to a stored procedure!) but combining these three (SqlCommand, SqlParameter & SqlDataAdapter) seem to be causing me problems.

It's probably something stupid but if someone could take a look and point me in the right direction, I'd be very grateful.
Cheers,
Jim

(Imperfect) Solution to TreeView Postback / Client-Side Node Selection Issue

  

I've seen this question posted on all corners of the web... "How do I disable "AutoPostBack" on the ASP.NET 2.0 TreeView control?!"  Unfortunately, most of the answers either don't work, miss the point (don't work right), or boil down to "You can't do it."  I happen to know that this behavior worked perfectly in the IEWebControls TreeView that Microsoft released as an add-on prior to ASP.NET 2.0, however.  So I set out to find a solution for the ASP.NET 2.0 TreeView issue.

In a nutshell, the behavior that I and others are looking for is to have a TreeView rendered in a page that allows the user to expand, contract, and select nodes within the TreeView without causing a PostBack to the server.  This implies two things: (1) the most recently-selected node should be recorded as the currently-selected node [i.e., at PostBack time, the most-recently selected node is actually represented as the SelectedNode]; and (2) the selected node should exhibit the SelectedNodeStyle as specified in the TreeView declaration.

It appears that the TreeView engineers saw only two possible outcomes from selecting a leaf node in a tree: (1) immediately posting back to the server, or (2) immediately navigating to another web page.  They apparently did not consider option (3) just allowing selection in-place on the client, while waiting for a click on so

Help with updating database with values from Repeater control using c#

  

Hello, I'm new to ASP.NET 3.5 with C#. I really need some help.

I used a Repeater control to create a simple (editable) list where, when a user logs in, they can edit their list of expenses.  The ASP page works fine.

 My issue is with the code-behind.  I am really confused with how to extract the values from the repeater control. The FindControl method does not seem to be working.  Also, the code I am using resets my 'Amount' values back to 0.00. (0.00 is the amount the user sees when they first encounter the page).

 Here's a portion of the code on the ASP page:

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1"

            onitemcommand="Repeater1_ItemCommand">

.

<ItemTemplate>

.

<td><asp:Label ID="lblExpId" runat="server"  Text='<%# Bind("ExpId") %>'></asp:Label> </td>

 <td><asp:Textbox ID="lblExpense" runat="server" Width= "190px" Text='<%# Bind("ExpenseName") %>'></asp:Textbox> </td>

 <td><asp:Textbox ID="txtAmount" runat="server" Width= "100px"
