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.

C# - Reload The Information Of The Sharepoint 2007 Webpart After A Button Is Clicked From Another Webpart?

Dec 29, 2010

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.

Web Forms :: Dynamically Adding A Css Class?

Nov 18, 2010

I have a website built that uses master page templates. In the master page I have a simple menu in a list. This is not dynamic (yet!).

I am trying to put together some code behind to write a simple css class to one of the menu links if the Request.ServerVariables("URL") is equal to the current page URL

I have no code written because everything complains when I try to come up with something. I was thinking of doing it using a switch function but am I over complicating things?Below is the simple menu with the class I am trying to write to the link:

<div id="nav">
<li><a class="selected" href="Default.aspx" title=""></li>
<li><a href="" title="ThisPage.aspx"></li> [code]....

Web Forms :: Adding Multiple Usercontrols Dynamically?

Sep 21, 2010

I have a simple user control which contains a textbox and a dropdownlist. I need to add this control multiple times to my page then save the details to my db, validating each control. When they re-enter my page I need to load the user control for each record in the db populated with the data they entered. They can then edit the data, delete the row or add new rows.

I'm trying to find the cleanest most efficient way to accomplish this. I realise I would need to re-add the user controls after each postback re-populating the data. Would the best way be to add each row to an arraylist or list of type object, save it to the viewstate and re-add the controls with data on postback, or is there another method which would suit?

Web Forms :: Dynamically Adding User Controls

Sep 5, 2010

I am new to ASP.NET And I am have THE hardest time understanding how to work with forms in ASP.NET. Here's what I am doing:

Dynamically add User Controls to a PlaceHolder based on some int value (which currently is passed in a HiddenField).Fire an event if the WebControls inside of the User Control change, then handle that event in the Main Page (i.e. save the input to DB)When the user clicks the "Next/Continue" button, the next controls for the next page are loaded. And I guess maybe I just can't seem to get how things work in ASP.NET, because I am really struggling with the general idea of how ASP.NET flows.

Should I be dynamically loading the controls in Page_Init, or Page_Load? Or should I load the controls when the buttonclick event is fired?Do I have to add the axCtrl.OnDataChange += new EventHandler(HandleAxControlDataChange); line on Page_Load? Or should I put this in When I first load the UserControl, I need to initialize some WebControls within the UserContorl. Is there a way to know if I have loaded new user controls into my placeholder? I can't use Page.IsPostback, because after the first page, every page is a postback from the buttonclick.

Here's what I have:


Here's the markup from my ASPX file...

Web Forms :: Adding Text Box Dynamically On C# 2008?

Feb 25, 2010

I am working on an application, where a user will enter their primary information (Name, Address, Email, Phone etc), then enter their automobile information (usually a fleet of automobiles).

My web page currently has one row of text boxes (Car Make, Year, Model, VIN, Mileage, License Plate)

Below this is a button called "Add More Cars"

What I am trying to do here is allow the user to add more cars if they have more than one that needs to be registered.

My problem is how do I do this dynamically?

2nd problem, how do I collect the data entered by the user (for all cars), to be able to write them to the database?

Web Forms :: Anomaly When Dynamically Adding/deleting Controls?

Mar 15, 2010

I have a page where a user can add any number of a specific custom control by clicking a button and delete any of them by checking a "delete" box and clicking the delete button. This custom control has a dropdown, 3 radiobuttons, 2 text boxes and 2 checkboxes. The anomaly occurs when you add at least 2 controls, then delete any of them but the last one.

When each control is rendered the name and id attributes are autoincremented to make them unique however, in the above casewhen the custom control is actually renedered to the page the name attribute has an index that is 1 higher than the id. For example:

here is the name and id of the problem radio button: name = ctl00$ContentPlaceHolder1$PreOpUpdatePanel$PreOpStatcompareinout1$AllInOut but the id = ctl00_ContentPlaceHolder1_PreOpUpdatePanel_PreOpStatcompareinout0_All

Now I am sure that I am doing somethign wrong but I just do not know what. Since the controls are added dynamically I have to recreate them on each postback so that the postback data can repop the fields. However, when the user deletes then the postback event makes me recreate all of them, then I have to remove the controls the user requested to be deleted. At this point the auto generated index is incorrect so the nextpostback will lose the data so I have to manually renumber the control IDs. Now this seems to work on all other controls within my custom control except for the radio buttons.

Forms Data Controls :: Dynamically Adding Rows To A Table

Apr 19, 2010

I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.

Here's the design I want:

ddl1 | ddl2 | ddl3 | ddl4 | ddl5 | ddl6 | ddl7 | textbox

When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.

Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.

Web Forms :: Dynamically Adding Controls To A Table Across Multiple Functions?

Mar 13, 2010

I'm looking to add controls dynamically to a table across multiple functions. I'm trying to convert this from a C# app to a web app using asp.net, though this is my first time using asp.net with no web development background. I read the creating tables dynamically in the FAQ but I'm still not sure how to do this.

When pressing the submit button on my form, it will create a table in a place holder. Eventually I would like it to generate urls based on the users input and do this in a function other then the one I created my table in.

In my C# app I was able to add text to a listbox using: lstOutput.Items.Add("Text"); across multiple functions but I'm having trouble doing this with a table.

I understand that my table is a local variable in the submitButton_Click function, but how do I make it global to add rows, cells and controls to it in other functions?

My current code which doesnt work:
