Is there a way in VB.Net to embed a custom user control to a web page based on Word or Excel

Posted By:      Posted Date: September 11, 2010    Points: 0   Category :ASP.Net
Hi Everyone.  I'm looking to create a web page that would be used on a local intranet that would use a custom control based on Word and Excel.  I've used code previously to embed it in a Windows application but wasn't sure if anyone knew of any examples out there on how to embed a custom control into a ASP.Net page.

Knowing the event occured in user control in current page




      My web application has user control which uses third party controls called Devexpress controls. The user control is a menu  and is part of the Master page. It is placed there because this needs to be available in all the pages. My user controls raises a even on item clicked. Now, My question is that Is there any way to know that the event has occurred in page_load of the current page in which I am in?

User Control not accessing the value of the properties send to it from the aspx page.


I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as


<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>


but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong

the problem is eval is not passing the value to usercont

Adding a custom control to the SharePoint 2010 Team Site Wiki Page Template ( wkpstd.aspx ) programm

Topic This is maybe my last post about the Team Site Wiki Page customization with the aim of exceeding its limitations. This time we are going to customize the unique template ( wkpstd.aspx) by replacing the control that renders the editable content by a custom one. In this post example, we will take advantage of the use of this custom control to render not editable additional contents, for instance, a header and a footer that could be the same for a specific Wiki Page Library. Of course, we are not going to really customize the template, but we are going to use a delegate control to replace the control at runtime. Here are the screen shots of the result: We can see a non editable Header and Footer on the Team Site Wiki Page In edit mode these additional contents are not rendered, but we can add new content as usual And of course, after having saved the page, the new content is rendered wtih the non editable Header and Footer. Steps required   If you look at the Team Site Wiki Page template, wkpstd.aspx, you can see the control that is rendering the editable content/ <SharePoint:EmbeddedFormField ID="WikiField" FieldName="WikiField" ControlMode="Display" runat="server" /> We are first going to create a custom EmbeddedFormField control Then, we are going to use a delegate control to replace the native EmbeddedFor

How to Access Parent Page (.aspx) control (IDs) from its child User Control (.ascx)

I have a parent .aspx page that has a asp:panel control in it, and this parent .aspx is also referencing a user control that I registered in that .aspx. Lets just call it usercontrolA.ascx for this post.The user control has a radiobuttonlist itself.Based on a selection from the radiotbuttonlist in the user control, I want to be able to hide the asp:panel in my .aspx (parent) but unfortunately I cant' get it to work:parentPanel.visible = true;  <<< I trried this in usercontrolA.ascx.csBut the user control doesn't know about the panel in the parent .aspxSo do I need to expose that somehow from the parent so that I can access it from the code behind of the child .ascx?  How?

Accessing User Control that is in a Master Page

I have looked everywhere for how to do this and all I come up with is threads describing how to expose public properties.  I have a USER CONTROL in my  Master page. It is a search box with a text box and a dropdown for search type (last name, account number, etc) and a search button.  When the user clicks the search button, I open a new page that displays the results.  How do I pass the values from the USER CONTROL search fields to the new page?  I would post code, but I have nothing to post yet since I don't know where to start. I have tried exposing the public property of the user control, but I don't know how to retrieve those values on the results page.  Anyone have any sample code on how this is done? Thank you in advance for your help!

Problem binding business objects to custom user control properties

I have created a user control (supplierPicker) intended to allows a supplier database to be searched and a supplier selected. I want to be able to use this control in a number of other user controls, by binding the suppplierID property of the supplierPicker to a supplierID property in a business object, which is set as the datacontext of the parent user control. When I do this, and there is a supplierID specified in the business ofbject, the binding sets the supplierID in the supplierPicker control and it shows the correct supplier name in the textbox. However when the supplierID DependencyProperty is changed from within the supplierPicker the newly selected supplier name is shown in the TextBox, but the SupplierID does not propogate back to the business object. Other controls on the parent form work fine, so the binding to the business object seems to be ok. Any pointers as to what I'm doing wrong here would be grately appreciated.  This one has been driving me nuts for days! Snipped code for the supplier picker:         public partial class SupplierPicker : UserControl, INotifyPropertyChanged     {         public static DependencyProperty SupplierIDProperty;         public event PropertyChangedEventHandler PropertyChan

Document is read-only in SharePoint, but user sees "check out" option in Office 2007 / Word / Excel

I am finding that when there is a document library in SharePoint with checkin/checkout required, if a user with read-only ("Visitor") permissions opens a document from that library, the document will open as read-only in Word, Excel, etc., but the user will see the "Server Document" bar with the message "To modify this document, you must check it out" and the "check out" button.  When the user tries to check the document out, they are asked to authenticate, and then receive the error "Cannot perform this operation.  The file has been deleted or someone else has it checked out."    How is it possible to prevent a user with read-only rights in SharePoint from seeing the "Check out" option in Word or Excel?

Forms Based Authentication - problem with custom master page and login page



I have successfully enabled and set up FBA (Forms Based Authentication) on my SharePoint 2010 Foundation server. The thing is that I need to customize the look and feel of the login page. I have successfully customized the page (and master page) to look the way I want, however, when I try to log in, I get the following error/message on the page:
"Forms Based Authentication on classic Web applications has been deprecated".

What I've done:
Made copies of /_layouts/simple.master and /_layouts/login.aspx and renamed the copies. The markup in the master page is MUCH simpler than the original, but I've kept all the ContentPlaceholders that I don't use (most of them) in a hidden <asp:Panel at the bottom of the page.

I've changed the web.config file:
<authentication mode="Forms">
      <forms loginUrl="/_layouts/loginCustom.aspx" />

So, I'm not getting any errors on the page until I try to log in. When I use the default settings (login.aspx and simple.master) it works just fine (but damn that page looks ugly!).

Does anyone know what I might be missing?

Update: I believe the reason it doesn't work is because my custom login aspx is not part of the Claims Based Web Application (because it's sitting
