Add PDF Viewer Panel To Sharepoint WebPart
Feb 8, 2011Never worked with Sharepoint, but need to add a WebPart to display a PDF document. How does this work? There is currently some code to add a ReportViewer (SSRS) WebPart, but I need to replace it to display a PDF file (from disk). The PDF file is from a local/network path that is not served publicly. I need to get the PDF content streamed in a web part, setting the content-type along the way. If it helps any, my thoughts are to respond on a different URL (page in the same site), that simply takes some token (get params?) and streams a byte[] and sets the content-type as application/pdf - I could well be completely off the mark. You will need to be quite specific with steps and code/sample/links in the answer.

C# - Reload The Information Of The Sharepoint 2007 Webpart After A Button Is Clicked From Another Webpart?
Dec 29, 2010I am new in sharepoint development. I have 2 webparts attached on a page. The first webpart (MyTestingWebpart1) basically it does only inserting of data and the other webpart (MyTestingWebpart[2]) displays the records from the database. Now my problem is when I try to click on the save button, somehow I don't know how to refresh the webpart that displays the newly inserted record. Is this possible?
I have added a query at the page load event of MyTestingWebPart[2]. Both of the webparts attached are web user controls.

Web Forms :: Access Aspx Page Control In Webpart Class?
Jan 18, 2010i have a hidden textbox in my aspx page. The aspx page also has a masterpage in the <% @Page> directive.
<input type="hidden" runat="server" name="txtType" id="txtType" />
actually in aspx.cs i am getting txtType.ClientID="ctl00_MainHeaderContent_txtType"
I have a webpart in a webpart zone in this aspx page. In the webpart CreateChildcontrols() I need to access this hiddenTextbox value. I am able to access it as
string TxtValue = this.Page.Request.Form["ctl00_MainHeaderContent_txtType"];
But instead of hardcoding I want to access as a control in the page or form. How can I do that I want to do as looping through the controls in the page but Page.Controls.Count gives 1 and that is MasterPage. How can I get the entire controls in the page and loop through and find the hidden textbox. I also tried as string TxtValue = this.Page.Request.Form["<%=txtType.ClientID%>"] in CreateChildControls() of the webp[art. But could not access hidden textbox like this.
Web Forms :: Accessing Custom WebPart Control Using HTML Browser DOM
Jun 10, 2010does anyone know how to access a webpart using the HTML Document Object Model? for example: for a given page which contains a webpart manager and a webpartzone.
[Code]....
I cant access the custom control using the HTML DOM Like this: HtmlDocument doc = HtmlPage.Document;
HtmlElement element = doc.GetElementById("HostTest");
HtmlElement element1 = doc.GetElementById("silverlightControlHost");
HtmlElement element2 = doc.GetElementById("WebPartZone3");
HtmlElement element2Parent = element2.Parent;
HtmlElement element3 = doc.GetElementById("SLRoomConsumerPart1"); //element3 does not return anything at all just Null!
all of the other elements are returned except for element 3 which returns a null! Any controls (regardless if it is a custom control, ASP control, Usercontrol . i tried it by replaceing the custome control with an aspnet button. i go t a null value as well) placed in the <ZoneTemplate> Tag of the <WebpartZone> is not returned using the HTML DOM. I find this stupid and pointless, as the whole point of a webPart is that you can place all sorts of controls in it :
customcontrols, usercontrols html controls, html server controls, aspnet controls and you cant seem to get access to those controls using the HTML DOM model in codeBehind
<asp:WebPartZone ID="WebPartZone3" runat="server" Height="90%" Width="
<ZoneTemplate>
<cc1:SLRoomConsumerPart ID="SLRoomConsumerPart1" runat="server" />
</ZoneTemplate>
</asp:WebPartZone>
HtmlDocument doc = HtmlPage.Document;
HtmlElement my_WeBpart_Element = doc.GetElementbyId("myCustomWebPartControl1")
can anyone point me to a solution or a work around as i am trying to access the dom from silverlight 3 but should be exactly the same as doing it from the webpart'shosting page's code behind. so that i can reference the controls inside my web part from the code behind of the custom page once i get hold of the webPart Element referece.
Forms Data Controls :: Passing The Underlying Data Of The Databound Control?
Mar 30, 2010In my asp.net web page i have a dropdown box. Say like i have to bind EmployeeName to this dropdown box to show up as items.
I am using a dataTable to bind to this grid by having two columns in DataTable (EmployeeId and EmployeeName). But i am only binding the EmployeeName to the dropdown list box.
In the UI, after the user selects an Employee, I need to pass that employee's id to a function. Is there any way, i can directly pass the underlying data (EmployeeID in the DataTable attached to this dropdown), when the user selects the EmployeeName from the dropdown. Or i will have to make a roundtrip to the database and get the selected Employee's Id and then pass it to the function.

View 1 RepliesC# - Nesting A SharePoint Webpart Inside Of User Control?
May 4, 2010I know it's usually the other way around, but I have some extenuating requirements that must be met (read as "No one bothered to do the research and now I have to bail them out")
I have a standard user control (ascx) that is to be imported into a SharePoint 2007 website. Due to a design constraint, a sharepoint web part that is also needed has to be nested inside of this user control.
So in other words, the user control would have to look something like this:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="foo.ascx.cs" Inherits="foo" %>
<div id="container">
...snipped...
<!-- SharePoint web part goes here -->

C# - How To Get Gridview Underlying Datasource
Mar 2, 2011i have gridview in my asp.net web application under framework 3.5. I am binding the gridview with List. Inside the grid there is update and delete functionalities which are running fine. But my save functionality, for which i decided to extract the list back from the datasource and then through loop i will insert the new list to database. But when i tried to get it conventional way it returned me null.
I tried the following ways to retrieve the List back.
1. List<MyClass> list = (List<MyClass>gv.DataSource);
2. List<MyClass> list = gv.DataSource as List<MyClass>;
3. IDataSource idt = (IDataSource)gv.Datasource;
List<MyClass> list = (List<MyClass>)idt;
But no luck, each time i got null.
Web Forms :: WebPart Drag And Drop?
Feb 17, 2011I cannot get the Drag and Drop functionality of Web Parts is to work. I have a very simple test page with two WebPartZones.. In the OnInit method of the code behind I put the page in design mode. In the first zone I have a textbox.At runtime the text box renders as a web part. When I hover over the web part header my mouse pointer changes the 'move' pointer, but I cannot drag the item. I do not see it dragging and the part never moved. I am using Visual Studio 2010 with IE 8. I have tried IE8 in compatibility mode and regular mode. The results are the same. Here is the markup from my test page:
<form id="form1" runat="server">
<div>
<asp:WebPartManager ID="WebPartManager1" runat="server">
</asp:WebPartManager>
<asp:WebPartZone ID="LEFT" runat="server">
<ZoneTemplate>
<asp:TextBox ID="tb" runat="server" />
</ZoneTemplate>
</asp:WebPartZone>
aa
<asp:WebPartZone ID="RIGHT" runat="server">
</asp:WebPartZone>
aa
<asp:EditorZone ID="EditorZone1" runat="server">
</asp:EditorZone>
</div>
</form>
Here is the code behind:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
WebPartManager mgr = WebPartManager.GetCurrentWebPartManager(this);
mgr.DisplayMode = WebPartManager.DesignDisplayMode;
}
What am I missing?
