textbox in the form but text_changed not working correctly

Posted By:      Posted Date: October 22, 2010    Points: 0   Category :ASP.Net
 

Hiya,


I got a textbox in my form and I want to when a user start typing in the textbox the listbox below the textbox will select the item that starts with that string


for example, it i type I

than in myserver side code will call that SearchString method which will go through that listbox and do the rest...

protected void CountryTxt_TextChanged(object sender, EventArgs e)
    {
        string s = CountryTxt.Text;
        SearchString(s);
    }


the problem is it only stops in the textchanged after I press the enter key; it doesn't seem to work just by typing the characters in the textbox...

<asp:TextBox ID="MachineTxt"
         runat="server" Width="42px"
         ontextchanged="CountryTxt_TextChanged" AutoPostBack="True"> </asp:TextBox>

Can someone give me some indications whether I'm doing something wrong ?

Cheers

Automatically populating Contact Selector not working in Form Services

  
Hi,I'm currently working on a form where i wan't to automatically populate a contact selector control with a users manager. I've got the managers userid, called the ResolvePrincipal webservice provided by sharpoint, and set all the values in the contact selector with the correct values. When previewing it works perfectly however when i move the form to Form Services it won't work.I've tried setting it via rules: i.e. on the change of a textbox write the manager values to the contact selector.I've tried setting the default values of the contact selector to fields where i write the manager values.I've tried setting it through code i.e. SelectSingleNode() and SetValue() for each of the fields in the contact selector.All of which work fine in preview mode but will not work in Form Services, UNLESS the contact selector already has a user in it. So if the contact selector is blank it won't work, however as soon as i manually select a user then try using any of the previously mentioned methods of setting the control it works. While using code i get a nullreferenceexception which leads me to think that possibly when theres no user in the control the xml nodes representing the AccountId, DisplayName, AccountType don't exit???? TO throw another spanner in the works, on the very odd occasion it will work in Form Services as expected, after celebrating and trying again it returns

ReportViewer Print Button not working correctly with windows 7 clients

  
I need some help being pointed in the right direction to fix the following issue: - After building several reports using reportviewer and testing with windows XP clients everything seemed to be fine.  I noticed that the first time the client loaded the asp.net website and clicked the print button it asked permission to install a small file (I assume this is to allow the reportviewer to access the clients printers).   - The problem I have is on Windows 7 Clients.  They can view/export the reports with no problem, but when they click the print button it ask permission to install the small file, but a error is given during the install process and the file is not installed.   If anyone has a solution or can point me in the right direction it would be helpfull.  I am using Visual Studios 2008 on Windows XP PRO and the site is hosted on Windows Server 2003 R3   Thanks 

Incomming Email Not Working Correctly in SharePoint 2010

  
Hello everyone, We recently upgraded from SharePoint 2007 to 2010. Prior to the upgrade I had two SharePoint Document libraries setup to receive incoming emails. We had two reports scheduled in Reporting Services and each report emailed a document library once a week. After the upgrade this stopped working. The reason this stopped working was because the file names of the attachments were the same each week, however in 2007, sharepoint would append a random 4 digits to the end of the file name. Was the removed from 2010 on purpose? After discovering this didn't work, I decided to create a workflow on these lists that anytime and item is added go change the file name to include the list ID to ensure that the file names will be unique. Only to find out that items added to the list from the incomming emails do not trigger the workflow. Doing some research on this and it looks like it was turned into Mircosoft as a bug in 2007 which had a fix, but the fix is only for 2007 is doesn't say it applies to SharePoint 2010 so I don't want to install it. Anyone know if there is a fix for this in SharePoint 2010? Thanks in advance, Matt

What service is responsible for Calendar Overlay working correctly?

  
I'm having 2 issues with my SharePoint server.  User Profile Sync stuck on starting and Calendar Overlay not working. I created a calendar overlay a month ago, containing 7 other calendars and it works fine.  It currently still works if I add items to one of the 7 calendars, those items show up on the calendar with the overaly. But if I try and create a new calendar and add overlay to it - containing different calendars, nothing appears.   No calendar items from the overlay calendars that I've added. This has only started happening since my User Profile Sync stopped working - are the two related, somehow? I get no errors at all - just a blank calendar!  Frustrating!! Thanks for any help.  

Binding list to form not working with '&' character in list field data

  
Hi, I have a SharePoint list with a field called Title. I have a form based on this list with the field bound to the form as a label (for workflow to access). Here is the code for the form field. <asp:Label runat="server" id="ff2{$Pos}" text="{@Title}" __designer:bind="{ddwrt:DataBind('u',concat('ff2',$Pos),'Text','','ID',ddwrt:EscapeDelims(string(@ID)),'@Title')}" /> I have a workflow that runs through a form action button which take ff2 (title) and  does other stuff. The problem I have is with records where the value of 'title' contains the '&' character (example ab&cd). Blank is pulled in by the workflow when I get the value of ff2. I am guessing it has to do with the data binding and/or escape (special) characters coming through but I don't know how to fix it. Any help will be greatly appreciated

TextBox AutoPostBack not working when handling other DHTML event

  

I have to format a number in a TextBox while it is being typed. Right after the TextBox looses focus, I need to do other processing on server side, including some database queries.

I'm doing the formatting by handling the onkeyup event, client side. But when I add the handler, the onTextChanged event stops firing on the server. I've tried different return values for the handler but unfortunatelly I'm stuck.

To reproduce the problem, here is a sample where the formatting function was replaced by a simple "convert to uppercase" function. You'll see that, contrary to the expected, the Label doesn't get filled when the TextBox looses focus. It does get filled, however, if the user presses the ENTER key.

What can I possibly be doing wrong with such a simple task?

 

<%@ Page Language="VB" %>

<script language="VB" runat="server">

Sub Page_Load(ByVal Sender As Object, ByVal E As EventArgs)

'' Adding the event handler like this has the same effect as adding it inline

'txtTextBox.Attributes.Add("onkeyup", "return(upperCase(this));")

End Sub

Protected Sub txtTextBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs)

lblTextBox.Text = S

Save Changes not working correctly when SQL table has a trigger

  

Hi all,

My WCF isn't working currently when a SQL table has a trigger on it that updates a column.

My table:

(SalesID int, SalesNumber nvarchar(10), OrderType nvarchar(3), OrderDate datetime) the trigger creates a new formatted string value for SalesNumber based on the OrderType and the SalesID, e.g GRN00001

The trigger is applied when the WCF service adds a new record. But the return values for SalesNumber is still NULL. I'm not sure why it will not update. If I restart the programme it retrieves the correct data...

public tblSales tblSales_Save(tblSales dsUpdated)
{
  db.tblSales.ApplyCurrentValues(dsUpdated);
  db.SaveChanges();
  return dsUpdated;
}

public tblSales tblSales_Save(tblSales dsUpdated)
{
  db.tblSales.ApplyCurrentValues(dsUpdated);
  db.SaveChanges();

  tblSales dsNew = tblSales_FindID(dsUpdated.SaleOrderID);
  return dsNew;
}


Neither way works...

 

 

 


Multiple issues with dropdown list controls not working correctly

  

Overview
I am using WSS 3.0 and SharePoint Designer.  I have modified one of the items in my NewForm page so that I have a filtered lookup using a spdatasource. The filter works great, but my issue is that I can't seem to save the users selection back to the list itself.

Issue when using an ASP.NET dropdown list
I am able to bind the filtered spdatasource to an ASP.NET dropdown list control, however the item that is selected in the dropdown list is not being saved back to the list.  I am guessing that this is because the dropdown list itself is not tied directly to the appropriate list item, but... I can't seem to figure out how or where to do this.  I don't see anything in the data properties box in SharePoint Designer that allows me to tie the data back to the list itself.  Maybe I am just overlooking it somewhere?

Issue when using the native SharePoint Data View DropDownList with a filtered spdatasource
When I select "Data Fields..." on the dropdown control I get the Change Data Bindings dialog box.  From here I can select a data field to save the value back to (which resolves the issue noted for the asp.net control) and I can select my spdatasource, but... the display text and value fields below that never populate.  Thus, the dropdown list is empty when the user is filling ou

Howto add selected item from dropdownlist to a textbox on the same form?

  

 I have been trying to figure out what the proper method is to be able to have a dropdownlist on the same form that holds a number of textboxes for properties. I am using a strongly typed typed view which was generated by the Visual Studio IDE so it contains textboxes for all of the properties of my strongly typed class.  The class has a few properties that can have a set of possilbe answers; I'd like to displat those possible answers in a dropdownlist and then when the user fills in the form and clicks the submit button the selected item would be transferred to the correct property. I have a solution but think there must be a better solution out there and was wondering if anyone might point me in the right direction.

So say I have a model with 3 properties, FirstName, LastName. and MaritalStatus.

If I generated a view for this then I'd get an aspx file with the following:

-------------------------------------------------------------------------------------------

    <% using (Html.BeginForm()) {%>
        <%: Html.ValidationSummary(true) %>

        <fieldset>
            <legend>Fields</legend>
            
            
            <div class="editor-label">
                <%: Html.LabelFor(model => model.FirstName) %>
            </div>

Second instance of Reporting Services not working correctly

  

Background:

Need to access Reporting Services from outside firewall. The IT department installed second instance of RS on a box outside the firewall and pointed it to the Report Server inside the firewall. The application that runs the reports uses Forms Authentication and appears to working correctly. It picks up the "cookie" from RS and calls the report with the cookie in the header.

The Problem:

The call to programmatically login to RS works...but when the report is requested, a page comes up and asks the user to enter the username and password for the "data source". Once a "sql server user" is entered, and the user clicks on the "View Report" button, the report comes up. Why is RS asking for credentials for the report's data source???

Is there a trick to having nested hover-menus hidden correctly when entering a form.

  

I have nested hover-menus controls that I used to create an interactive menu.  After I use each control once, it works fine. but when I first enter the form, when I hover over the parent hovermenu, the others pop-up as well until I click on them once.  After that, each of them work fine.

What can I do to stop that from hapening
