dynamic javascript of an .ascx control inside an updatepanel not changing on client between async po

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

UpdatePanel Reference in control.ascx.designer.cs keeps changing

  

I have an annoying problem when I'm developing in Visual Studio 2010. I am using an UpdatePanel in my .ascx file like this:

<asp:updatepanel id="upStuff" runat="server">....</asp:updatepanel>


in my control.ascx.designer.cs, the update panel is being defined like this:

protected global::System.Web.UI.WebControls.WebParts.updatepanel upSettings;


this produces the error:

"The type or namespace name 'updatepanel' does not exist in the namespace 'System.Web.UI.WebControls.WebParts' (are you missing an assembly reference?)"


The actual namespace should be System.Web.UI.UpdatePanel. When I go directly into the designer.cs file and change it, it works. However, every time I go back into editing control.ascx and save, Visual Studio always changes it back to System.Web.UI.WebControls.Webparts.updatepanel.

I'm not sure what is causing this. Is it how I should be referencing namespaces and classes in my project? I'm using .NET 3.5. Any help would be greatly appreciated.


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?


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!

Updating an ASP.NET CheckBoxList inside an UpdatePanel from a Javascript function

  

Hi

I have a asp.net listbox server control that is connected to a jquery plugin that can handle a client side click event for each of the checkboxes it renders.

Whenever I click on a checkbox the click event gets triggered and I make a call to

__doPostBack("UpdatePanel1"""); so that i can update the updatepanel and rebind the checkboxlist inside it.

is it possible to do the rebind first, and then update the updatepanel? how do i do that? because now, the rebind happens on the second time i click on the checkbox.

Thanks

ASP Image inside UpdatePanel changing ImageUrl

  

Hello.

I have a WebForm which has an update panel. Inside the panel I have an ASP Image. I have also, 2 ImageButtons which act as the triggers for the UpdatePanel.

<asp:UpdatePanel ID="updImage" runat="server">
     <Triggers>
          <asp:AsyncPostBackTrigger ControlID="btnBackward" EventName="Click" />
          <asp:AsyncPostBackTrigger ControlID="btnForward" EventName="Click" />
     </Triggers>
     <ContentTemplate>
          <asp:Image ID="Image1" runat="server" Width="75px" Height="75px" BorderStyle="Solid" BorderWidth="5px" BorderColor="White" />
     </ContentTemplate>
</asp:UpdatePanel>

In my WebForm, I also have an ASP Image component outside the Update panel.

The ImageUrl of those ASP Image components are loaded from a folder that is outside the WebSite root folder, using the code found in this link:

LinkButton inside UpdatePanel not executing onClick javascript

  

Hello.

So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.

<asp:ImageButton ID="imgPdf" runat="server" ImageUrl="~/Images/pdf.png" OnClick="LnkRelease1_Click" ToolTip="Document1.pdf" Width="31px" />

<asp:UpdatePanel ID="UpdatePanel9" runat="server">                                                                                    
<ContentTemplate>

<asp:LinkButton ID="LnkRelease1" runat="server" OnClick="LnkRelease1_Click" ToolTip="Document1.pdf" Font-Underline="false">View Pdf</asp:LinkButton>

</ContentTemplate>

</asp:UpdatePanel>



As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window
using javascript (Code Behind of the MasterPage):

protected void LnkRelease1_Click(object sender, EventArgs e)
{
     try {   if ((((System.Web.UI.WebControls.WebControl)(sender))).ToolTip != "") { string script = @"

Javascript allert inside AJAX UpdatePanel not working

  

I am having problems with alert box not popup when I'm using AJAX UpdatePanel. The following is what I have and it's not working.

1    ClientScriptManager csm = Page.ClientScript;
2    
3    if(!csm.IsStartupScriptRegistered(this.GetType(), "winPop"))
4    {
5    	csm.RegisterStartupScript(this.GetType(), "winPop", "alert('Update is successful');", true);
6    }
  

I have to stress that the reason why it does not work is because I'm using AJAX UpdatePanel. If I turned off the AJAX UpdatePanel then it works perfectly. So does anyone have solution to go around this AJAX UpdatePanel issue?


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

Find Control inside a View of Multiview using Javascript (document.getElementById)

  

Hi,

i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function. 

On the HTML code is rendered only the first view or the view that is activated on page load.

Is there any way to find a control inside the view using javascript? or I am doing something wrong?


Thanks a lot.
