We have a webpart that has 2 user controls.
We want the second user control to be able to read a value from the first user control.
One solution we have considered is an event in the first control, that updates a value in second user control. But not sure where to place / hook up the events so that this works.
I 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.
I am just started development in ASP.NET.
I have created one sample application for WebParts. It is working fine when I run it from Visual Studio or local environment.
But when, I have publish file in IIS virtual directory (in my PC or same PC) at that time it is stop showing Verb tool bar (minimize, close buttons of WebPart).
I have one problem related to IP, I hosted one web-service on my server and give access of this web-service to other peoples/company, I want to authorize very few users for this web-service, I am also having username-Password concept, but I want to check user IP also.
Means to say only authenticate and registered IP will use my web-service/Application, so my main problem is that how can I get the IP address who are hitting my server, I want to communicating server IP address.
I need to do the following
1. Authenticate from Active Directory
2. Get Email List of all users from active directory
I have user credentials when system authenticates user but later on when I need to get the list of email from active directory I don't have user credentials for creating Directory Entry. I don't want to store credetials in Sessionstate or something and I don't want to use Admin Account. Plz suggest some solution so that I can connect to active directory for getting other information after authentication.
i want to use caching in my application
bcz i am depending on same data and in diffrent places i am communicating with database for this data
so i want to use caching and want to store this data after use login into application.
am writing a series of WSS/MOSS webparts amongst which one will need to detect the current SQL Server database connection, prompt the user to setup a new connectionstring, and fire appropriate stored procedures to create a new database if needed. The user needs to be presented a textbox or label control with the current database connection. I've never had to detect current database connection, what methods do I call for this? If the desirable connection is not present, the web application needs to prompt the user to make a new database. The user really won't make the database, they simply need to click the command button which will fire the stored procedure to create the database.
View 1 RepliesI am hoping someone has experience with this, but I am loading a window from a link on my main page. The window loads an ASPX page via the window's loadmethod of iFrame. The aspx page has its own update panel on it and I was wondering how I can call the window's "spinner" / process indicator while the page is processing. I have looked at the documentation on some online information about it but I am not sure how to implement it.
View 1 RepliesI have created 2 projects in a solution. One project contains Asp.net classes with login page and different other pages.
Another project contains a web service.
When I launch the solution(click F6 in visual studio 2008) the login page can access to the method of the webservice. Both projects are launched.
However when i added this 2 projects into IIS and deploy them (with create command) the login page cannot contact the method of the web service. Even though the web service is running because i can acces it manually. But they cannot communicate each other.
I am coding in ASP.NET C#. I have Microsoft Dynamics GP hosted at a server and my database hosted at another server. I would like the GP database take value from some table there and synchronise it with my database. Which is the best alternative? Data transmission Service(DTS)?
View 1 RepliesI need to place a webpart on the page. The webpart need to change Welcome control title. I need to change "WelCome UserName" to "UserName".
I tried http://www.wictorwilen.se/Post/Having-fun-with-the-SharePoint-Welcomeascx-control.aspx , But it did not worked in Webpart.
I 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?
I am trying to set different backgroundcolor of each webpart title. But unable to do that.
View 1 RepliesI'm currently working on a highly configurable Database Viewer webpart for WSS 3.0 which we are going to need for several customized sharepoint sites. but i fear it's necessary to recap the whole issue. As background information and to describe my problem as good as possible, I'll start by telling you what the webpart shall do:
Basically the webpart contains an UpdatePanel, which contains a GridView and an SqlDataSource. The select-query the Datasource uses can be set via webbrowseable properties or received from a consumer method from another webpart. Now i wanted to add a filtering feature to the webpart, so i want a dropdownlist in the headerrow for each column that should be filterable. As the select-query is completely dynamic and i don't know at design time which columns shall be filterable, i decided to add a webbrowseable property to contain an xml-formed string with filter information.
So i added the following into OnRowCreated of the gridview:
void gridView_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
for (int i = 0; i < e.Row.Cells.Count; i++)
{
if (e.Row.Cells[i].GetType() == typeof(DataControlFieldHeaderCell))
{
string headerText = ((DataControlFieldHeaderCell)e.Row.Cells[i]).ContainingField.HeaderText;
// add sorting functionality
if (_allowSorting && !String.IsNullOrEmpty(headerText))
{
Label l = new Label();
l.Text = headerText;
l.ForeColor = Color.Blue;
l.Font.Bold = true;
l.ID = "Header" + i;
l.Attributes["title"] = "Sort by " + headerText;
l.Attributes["onmouseover"] = "this.style.cursor = 'pointer'; this.style.color = 'red'";
l.Attributes["onmouseout"] = "this.style.color = 'blue'";
l.Attributes["onclick"] = "__doPostBack('" + panel.UniqueID + "','SortBy$" + headerText + "');";
e.Row.Cells[i].Controls.Add(l);
}
// check if this column shall be filterable
if (!String.IsNullOrEmpty(filterXmlData))
{
XmlNode columnNode = GetColumnNode(headerText);
if (columnNode != null)
{
string dataValueField = columnNode.Attributes["DataValueField"] == null ? "" : columnNode.Attributes["DataValueField"].Value;
string filterQuery = columnNode.Attributes["FilterQuery"] == null ? "" : columnNode.Attributes["FilterQuery"].Value;
if (!String.IsNullOrEmpty(dataValueField) && !String.IsNullOrEmpty(filterQuery))
{
SqlDataSource ds = new SqlDataSource(_conStr, filterQuery);
DropDownList cbx = new DropDownList();
cbx.ID = "FilterCbx" + i;
cbx.Attributes["onchange"] = "__doPostBack('" + panel.UniqueID + "','SelectionChange$" + headerText + "$' + this.options[this.selectedIndex].value);";
cbx.Width = 150;
cbx.DataValueField = dataValueField;
cbx.DataSource = ds;
cbx.DataBound += new EventHandler(cbx_DataBound);
cbx.PreRender += new EventHandler(cbx_PreRender);
cbx.DataBind();
e.Row.Cells[i].Controls.Add(cbx);
}
}
}
}
}
}
}
GetColumnNode() checks in the filter property, if there is a node for the current column, which contains information about the Field the DropDownList should bind to, and the query for filling in the items.
In cbx_PreRender() i check ViewState and select an item in case of a postback. In cbx_DataBound() i just add tooltips to the list items as the dropdownlist has a fixed width.
Previously, I used AutoPostback and SelectedIndexChanged of the DDL to filter the grid, but to my disappointment it was not always fired. Now i check __EVENTTARGET and __EVENTARGUMENT in OnLoad and call a function when the postback event was due to a selection change in a DDL:
[Code]....
When i have two or more filters set which return zero rows, and i change back one filter to something that should return rows, the gridview remains empty (although the pager is rendered). I have to completly refresh the page to reset the filters. When debugging, i can see in the overridden CreateChildControls of the grid, that the base method indeed returns > 0, but anyway.the gridView.RowCount remains 0 after databinding. Anyone have an idea what's going wrong here?
I need to set the webpart to administrators only. How can I allow only shared scope. User scope is not allowed even for administrators.

View 1 RepliesI have built a few custom applications that run on WSS 3 using the Visual Studio 2010 Web application template. When I compile the application, Visual Studio creates the assembly file in the bin directory which I copy over later to the production server (another machine) with WSS 3. The compiled application dll file is copied into the bin folder inside the virtual directory of WSS and runs fine in there

Never 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.
View 2 RepliesI've been using the session array to store a state variable for my webpart... so I have a property like this:
public INode RootNode
{
get
{
return this.Context.Session["RootNode"] as INode;
}
set
{
this.Context.Session["RootNode"] = value as object;
}
}
This usually works fine. I've discovered that sometimes, the context.session variable will be null.
I'd like to know what are the conditions that cause the session to be null in the first place, and whats the best way to persist my object when this happens? Can I just assign a new HttpSessionState object to the context, or does that screw things up?
Edit: Ok, so its not just the session that is null... the whole context is screwed up. When the webpart enters the init, the context is fine... but when it reaches the dropbox selectedindexchange postback event (the dropbox contains node id's to use to set the rootnode variable), the context contains mostly null properties.
also, it only seems to happen when certain id's are selected. This looks more like some kind of weird bug on my end than a problem with my understanding of the session.
I am trying to read the data from XMLDataSource into a gridview (in asp.net). It works when I perform below logic:
Dim ds As New DataSet()
ds.ReadXml(Server.MapPath("LoadData.xml"))
GridView1.DataSource = ds.Tables(0)
GridView1.DataBind()
and I hardcoded the resultant hyperlinks inside the GridView with some name using the following exp: (and it works).....
But when i embed the griview inside a webpart , configure the datasource, I am not able to read the data from the XMLDataSource. I get the following error: The DataSourceID of "GridView1" must be the ID of a control of type IDataSource. A control with ID "XMLDataSource1" could not be found.
