Forms Data Controls :: Trying To Show Literal Value Instead Of Foreign Key - Visual Basic
Apr 26, 2010
For my Dynamic Data site I have a table that has a join to a number of other tables. If I use the standard page for this table I get all of my columns from the primary table and related tables (which is good) and the appropriate literal values from the related table (which is great). The bad part is the order of the columns.
To address the order of the columns I created Custom Folder/Page for the table. I also have a partial class that controls date formatting. This takes care of the ordering of columns fine (which is a step forwared), but now I'm seeing the foreign key IDs instead of the literal values from related tables (which is a step backward).
All I did was copy the standard page to the Custom folder for the table, turn off AutoGenerateColumns, and specify the column order and display name. Why would the foreign key change occur? As a side note, if addressing column order in the partial class is the preferred method I could go that route, but I haven't been able to understand how to do that in VB (I've seen many examples in C#, but that's not my strong point).
Is there a way to delete an entire gridview with code? I have a gridview that is created based on a value is selected in another gridview, and the bound columns keep being created on top of the previously created gridview. I would like to completely delete it and create it anew based on the new selection.
I'm trying to pass a value (address) from a listview control using visual basic to a google map address control on the page load event. Here is the code I have so far in vb:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'Pass address from Listview to Googlemap address GoogleMap1.Address = ??? GoogleMap1.Zoom = "14" GoogleMap1.ShowScaleControl = True GoogleMap1.EnableInfoWindow = True
XElement Categories = new XElement("Promotions", from b in db.GetPromotions() select new XElement("Promotion", new XElement ("Category",b.CategoryName), new XElement("Client",b.ClientName), new XElement("ID",b.ID), new XElement("Title",b.Title))); XDocument mydoc = new XDocument(); mydoc.Add(Categories); try { // Load the style sheet. XslTransform xslt = new XslTransform(); xslt.Load(@"C:WebDesktopModulesPromotionsTransList.xslt"); // Execute the transform and output the results to a writer. StringWriter sw = new StringWriter(); //XsltSettings mysettings = new XsltSettings(); XmlWriterSettings mysettings = new XmlWriterSettings(); xslt.Transform(mydoc.CreateReader(),null, sw); String mstring = sw.ToString(); It generates the following string: <ul id="red" class="treeview-red" xmlns:asp="http://schemas.microsoft.com/ASPNET/20"> <li><span>Arts & Entertainment</span><ul> <li><span>Client 1</span><ul> <li><span><asp:LinkButton ID="LinkButton2" runat="server" OnClick="LinkClicked" Text="Get your Free 2" /></span></li> <li><span><asp:LinkButton ID="LinkButton4" runat="server" OnClick="LinkClicked" Text="Get your Free 4" /></span></li> <li><span><asp:LinkButton ID="LinkButton5" runat="server" OnClick="LinkClicked" Text="Get your Free 5" /></span></li> </ul> </li> </ul> </li> <li><span>Community & Neighborhood</span><ul> <li><span>Client 2</span><ul> <li><span><asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkClicked" Text="Get your Free 1" /></span></li> </ul> </li> </ul> </li> <li><span>Education</span><ul> <li><span>Client 3</span><ul> <li><span><asp:LinkButton ID="LinkButton3" runat="server" OnClick="LinkClicked" Text="Get Your Free 3" /></span></li> </ul> </li> </ul> </li> <li><span>Home & Garden</span><ul> <li><span>Client 4</span><ul> <li><span><asp:LinkButton ID="LinkButton6" runat="server" OnClick="LinkClicked" Text="Get your Free 6" /></span></li> </ul> </li> </ul> </li> </ul>
Now I take the string and add it to a panel which is part of a view in a multiview control: Panel1.Controls.Add(new LiteralControl(mstring)); I have tried to play with Page.ParseControl, but I cannot get it to work right in the panel, the linkbuttons do not show, even though the text is there in the source. Now I tried this: Control myctrl = Page.ParseControl(mstring); Panel1.Controls.Add(myctrl); and I get this as the one of the controls:
a id="dnn_ctr954_ViewPromotions_LinkButton2" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("dnn$ctr954$ViewPromotions$LinkButton2", "", true, "", "", false, true))">Get your Free 2</a>
It doesn't work the way expected, dotnetnuke is doing some nutty stuff here using the parse control. it seems to drop my LinkClicked event.
I need to write a paper on the comparison between (Microsoft Visual studio 2005 to develop web applications using asp.net) and (visual basic and Netbeans to develop j2ee applications using java).I need suggestions for good webpages,journals or documents which can help me out here.

I try to mak a custom textbox. Something pretty easy to do but I can't figure out one thing. When I write my textbox in designmode I have this <custom:Textbox runat="server" ID="Textbox1">Test</custom:Textbox> The problem is The textbox is a webcontrol I added to my class [Parsechildren(false)] like this [Parsechildren(false)]
public class Textbox : WebControl { }
now the problem is I want to able to write the Text from the textbox between the beginningtag and andingtag but I want to disable every other control in designmode. When I add < between the tags then you can see you can write all tags between it. disable all controls except literal between the tage in designmode?
I have declared a variable as public (Visual Basic 2008). As a result I can call its value in all subroutines. However I cannot change its value in any of the subroutines?! How to do that? The variable I'm having trouble with (see code below) is called 'antwoordbestand' and I want to change its value in subroutine startKnop_Click.

I have Repeater, which consists of LinkButon and Literal. LinkButon and Literal are whole thing by implication. I want get value from Literal, when user click on corresponding LinkButton.
I want to change the value of a literal within a repeater ItemTemplate after postback, based on a value detected at postback.I can't render the whole repeater again though I think because it's actually a radio button in the control that inititates the postback and so I need that control / value to be persisted.
I am just taking a shot in the dark through this whole thing. I have an Addresses table with a StateID and CountryID field. They refer to the States and Countries table. I am using LINQ to SQL and Visual Studio 2010.In my AddressesController I have:

I created an AddressViewModel and it looks like this:
[Code]....
Then in my view code I have:
[Code]....
So when I try to go to Addresses/Create I get this error: ArgumentNullException was not handled by user code:Value cannot be null.Parameter name: itemsAnd it points to this line in the AddressViewModel:

VWD 2008 Express. Visual Basic.I have a customvalidator on my page and a corresponding OnServerValidate routine tied to this control in my VB code behind. I also have a "Save" button that is defined as "CausesValidation=True." I placed a breakpoint in my OnServerValidate code for the customvalidator and a breakpoint in my OnClick routine for the Save button. What I expect to happen is that when the "Save" button is pressed, all the validation is checked before ever entering the OnClick code for the Save button. If any of the validators are false, then I expect that the Save button OnClick code will not run.
I'm working to develop a website application for my client. Unfortunately, my client does not want to spend the money to host it. Is it possible to host the whole program with the database on his laptop without him installing Visual Basic?
