Web Forms :: Adding Webpart Page To Existing Application
Feb 19, 2010
What are the steps to implement webparts into an existing application that already has been set up to use asp.net membership? I have yet to see how to get this to work. The only thing I am accomplishing is generating the following error:
The specified connectionStringName, 'LocalSqlServer', was not registered. (C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Configweb.config line 312) at System.Web.Configuration.ProvidersHelper.InstantiateProvider(ProviderSettings providerSettings, Type providerType) at System.Web.Configuration.ProvidersHelper.InstantiateProviders(ProviderSettingsCollection configProviders, ProviderCollection providers, Type providerType).
So, what is the deal here? Is it because my site uses masterpages? I have profile, roleManager, membership and connectionstrings in my web.config. I tried adding a webpart section, like I found on one website, to no avail. I was still getting the 'LocalSqlServer' error bunk.
I want to add WCF to existing asp.net application and host both of them in the same virtual directory is it possible ?? Also when i click new item to add app.config file from visual studio its not showing.
I have a problem on adding a webpart to sharepoint page.
I have a blank page in the sharepoint, and I have a custom control uploaded to the site, on adding the webpart the the sharepoint page I get the following error:
"Attempted to use an object that has ceased to exist. (Exception from HRESULT: 0x80030102 (STG_E_REVERTED))"
I get that error even if the sharepoint page is totally blank and so is the web part.
We have a web application written in ASP.NET for .NET 3.5, using standard web forms.
Going forward we want to start building new features, and over time migrate existing features, in ASP.NET MVC.
Is such a thing doable? Can we add the necessary files to an ASP.NET web application and thus "upgrade" it to be compatible enough with MVC so that we can start adding routes, controllers, views, etc.?
The old site is using a frameset containing a top header, a left menu, and a main content. What I envisioned was to create a new masterpage for all the existing pages, integrating all of those things into each page instead, and then start adding new pages using views instead.
I understand that unless we upgrade to .NET 4 we cannot use MVC 3, so the way I see it we have the following options:
Build a new website, somehow auto logon the new site with the same credentials when logging in on the main site, and link between the sites. I see tons of problems with this solution. Integrate ASP.NET MVC 2 into the existing software, adding the necessary files, and starting to add new content in MVC style, only fixing critical bugs in the old files, and over time migrate them over to MVC. Upgrade to .NET 4 and integrate ASP.NET MVC 3, pretty much the rest the same as option 2. Wait until we can schedule a full rewrite, likely to not happen in any foreseeable future. Don't do it, keep web forms.
Note that a full rewrite is out of scope at the moment, so some transitional period is the only option we can do right now.
Option 2 and 3 are the ones we want, the rest are just for completeness.
I have a custom webpart which i am adding to webpartzone dynamically.., in the custom webpart am loading a usercontrol which has Gridview in it with data. On the page load it is working fine, when i click the paging button of the gridview , then nothing is visible on the page...
I have a running ASP.NET web site. There is following problem with one of the forms:
One part of submitted data is added to database after "submit" is clicked. (to "table1") Another part is lost (not added to "table2", and no files uploaded) I have no source code of that project. So, because I cant edit existing page, I came to a decision to add new .aspx page to a running application with same functions as existing one. How can I do that? Or maybe you can recommend some other solution.
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 am writing to a CSV that will contain different customer information. Right now when I write to it, it overwrites whatever is in the path right now. Instead of overwriting I would like the new writer.WriteLine to append to the current CSV without overwriting it.
Code
[Code]....
Also, can anyone help me with writing the file to a different location other than my local project file? I need the path to become a server location instead of the CSV folder stored locally.
What options do I have for adding a blog to an existing ASP.NET Web Forms web site. Ideally it should be able to transition to MVS as and when my site does.
I need to add rows to an existing (maybe) datatable in a dataset that combines the IIS6 index search with my own sql table. I keep getting object reference errors.
I have Web Application which uses the Logged In User (Authenticated User) to query his Profile Data from Adabas/Unix using OLEDB. The application provides the user with about 21 different pages (Basic Info, Employment Info, Education, Dependants, Financial Info ...).
The web application has a master page, and each profile data page is based on a User Control loaded in the Child ASPX Page.
The Data Layer of this Web Application will have to undergo major modification, since we are migrating our legacy applications from Adabas/Unix to SAP, the development Team has prepared web services to query for the same Profile Data from SAP using Web Services. Now, we have to modify the web application to consume the web services instead of using OLEDB to query Adabas.
Since we are in the testing phase, and we have only very limited data in SAP, I have to provide temporary control to allow test query the Staff Profile for a Specified User (instead of the Authenticated User) and to select the Source:
1. SAP, or
2. Adabas.
So I am thinking to add the following "Control Section" in the Master Page:
[Code]....
See image below to clarify:
[URL]
Becuase the users defined in SAP are based on Dummy Data, so we want to allow the user to Enter the required SAP User, and he will select "SAP" from the Drop-Down-List. In this case, the program will query for Staff Profile Data from SAP for the specified "Staff ID" (txtSAPStaffID) instead of the Authenticated User. But, if "Adabas" is selected for the "ddlDataSource" then, it will default to the Authenticated User.
I noticed that when I am following the above technique, if I press "Go", the Staff Profile Data Page is disappeared, and when I navigate from page to another, the selection on the values entered in the "Control Section" in the master page are reset to default value, ie, the last values are not maintained.
Questions:
1. What is your feedback on the method I followed above ? Any other recommendations? I need very simple method.
2. Why the data page (the child page of the master page) is cleared (disappears) when I press the Go button ?
3. How to maintain the values selected when I navigate from one page to another ?
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 have a Gridview on my aspx page. On my page_load event I check for a record in the database, if the record exists for that row in the gridview I would like to add a new column in the same gridview and add a button control to it. This adding of new column in the Gridview should happen in the codebehind (c#). see the code I wrote for this, but when I run it, it does not create any column on the gridview page.
I 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
I have a similar scenario. Sharepoint --> Ascx Control Webpart --> ListView w DataPager. The thing is, when I use the QueryStringField everything works ok. The Pages, clicks, etc... The problem is that when you use QueryStringField(QSF) it reloads all the page when you navigate through pages (this is because it builds different urls using the QSF). Everything ok until now.
As I have other webparts in the same page that interact with this one, I don't want a full render of the page because the other webpart reloads entirely. So, if I take out the QSF the link to pages appear but when I click on them they won't load.
im workin on a project using web parts..i have two pages:the first one contains two webpartzones and a set of webparts. in the second one, i should have the same webparts in the first but organised in a specific form. now this page is considered as a template page which the user can choose to apply on his first page.when the user chose this page. the first one should organise its webparts in the second webpartzone in a way that looks the same as the order of the webparts in the second page.
I have my home page with asp.net webparts. I can do all operations like closing, minimizing, dragging webpart from one zone to another.But I find out one strange issue that when I modified home page of one user and logged out. then in same browser if I login for another user, same modification that I have performed for earlier user appears for the second user.
i 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
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.
I have web site with Dotnet 2.0 framework With Ajax1.0. Now My requirement is to add Web Application built in 3.5 framework not used Ajax at all. But I am getting Ajax Error
our company holds a dynamic website which is being hosted and config in IIS .now i wanna know is it possible to Add Ajax Controls or Ajax Control Toolkit to my website or if i have to make any updations and i want to do it with the help of update panel is it possible i can do with my existing website let's say adding New Pages (no modifications on prev page's) i already went through video of joe stagner how to add ajax to an existing project
is there any more changes do i have to make either in my IIS or on my Windows Server 2008 R2 to make the New Pages? how to add ajax to an existing project,as it will be a great help for me i wanna perform this thing exactly live on my production server so chances of any error should not be there.
I have a requirement where I have a webpart and two ImageButtons(imgGV, imgLV) and a hidden input textbox('ctl00$MainHeaderContent$txtType') in an aspx page. I need to change templates to this Webpart either to show results in "Grid View" or as "List View" on the click of this ImageButtons. I added code in the page_load of .aspx page as
When I am clicking the specific ImageButton, it has to write into hidden field either "GV" or "LV". In the webpart CreateChildControls I assign templates based on the text in Hidden field either "GV" (Grid Template) else "LV" (List Template). In the CreateChildControls of Webpart for the template change, I am getting the Hidden value as empty. I am using coding as
HtmlInputHidden t = new HtmlInputHidden(); t = (HtmlInputHidden)this.Page.FindControl("ctl00$MainHeaderContent$txtType"); if (t.Value=="GV") { assign one template} else { another template}.
I am getting t.Value="". Question is: Is it like if we add some text in a hidden textbox using the Javascript function in an aspx page, the same textbox value in the same aspx page but in the Webpart class in the CreateChildControls method using the code as this(webpart).page.FindControl("Textbox").text is showing empty. So the text added using Javascript into Textbox is it not available in the code behind code using "Text" property of the same Textbox?.
