Web Forms :: How To Show An Interconnected Web Of Items (similar To An E-R Diagram)
Jan 23, 2010
am a .NET developer with four years professional experience. In my free time I am looking at building a site that graphically displays relationships between objects, in this case, people. I don't want to spend any money on a web control as this is just for fun. Something that looks like this:
except with people (who know each other, or otherwise). I am having trouble starting this project out. I have the database designed with a People table (ID, Name) and a Relationships table (ID1, ID2), but don't know how to graphically display this information.

I know that I can convert a sequence diagram into a collaboration diagram easily using Rational Rose, but... Using Visual Studio, that is possible? Or I will have to create by myself?

I have data coming from two tables with a foreign key relationship - one User table containing users of the web application, and one Page table containing details about pages visited by each user.I would like to be able to view these data in a gridview or the like on a page. It's easy enough to just show the User table data like so (I'm using the Entity Framework and LINQ):
[Code]....
But how can I show the Page details? I'm not bent on any particular way of showing it, but the only idea I've been able to come up with is to have a dropdown list for each user in a column. But I can't figure out how to get the page data into such a dropdown list. The tables are associated with the primary/foreign key UserID.The closest I've come to finding something similar to this is this for Linq2SQL: http://weblogs.asp.net/scottgu/archive/2007/07/16/linq-to-sql-part-5-binding-ui-using-the-asp-linqdatasource-control.aspx , and this using more traditional data access: ttp://www.highoncoding.com/Articles/169_DropDownList_Inside_GridView__Method_1_.aspx . Either way, regardless of data access technology, I can't relate these solutions to my example and get it to work

I had used listbox control with multiple selection mode. I stored id with comma delimiter in database.
e.g.
1. List Item One.
2. List Item Two.
3. List Item Three.
4. List Item Four.
5. List Item Five.
6. List Item Six.
Suppose user select item 2, 4 & 6. So I will store it as a 2,4,6 in database. This will work fine.
Now in editing I have to shows selection-bar for item 2, item 4 & item 6. So I had typed below source.
string strData ="2,4,6"
if(strData != null)
{
char[] separator = new char[] { ',' };
string[] strSplitArr = strData.Split(separator);
int x = 0;
for (x = 0; x < strSplitArr.Length; x++)
{
// lstWDef_PurchasesEdit.Items[x].Selected = true;
lstWDef_PurchasesEdit.SelectedValue = strSplitArr[x].ToString();
}
}
But with this statement I got only last item id as a selected item with selectionbar. In our example 2,4,6 only item whoseid is 5 got as a selected item.
if i use
for (x = 0; x < strSplitArr.Length; x++)
{
if (lstWDef_PurchasesEdit.Items[x].Value == strSplitArr[x])
{
lstWDef_PurchasesEdit.Items[x].Selected = true;
}
}
if the selected items are serial like 2,3,4 then it is displaying correctly..
if items are 2,4,6 then it is not selecting the items of listbox properly.
Is anybody guide me how to make item 2, item 4, item 5 as a selected item ?

I am placing a dropdown list in the footer of a DataGrid like this:
[Code]....
In my code behind file, in the myDDL_OnLoad event handler, I call to the database, populate a SqlDataReader, and set the DDL's datasource to that datareader. I define what data columns should be used for the DataValueField and DataTextField of the dropdownlist. Then I call the DropDownList's DataBind() method. Everything works without error. But, when the dropdownlist is displayed, it has blank lines in it.
By that, I mean if 8 records are loaded into the dropdownlist, it will expand to a size appropriate for 8 rows but, it will be empty. there is no text in it.
Has anyone seen this type of behavior before? This dropdownlist is in the footer of a dynamically loaded ajax update panel so, it is difficult to see the source code to see what values are in the html element rendered to represent the dropdown.

I am using a SiteMap data source boudn to a navigation control. I would like to also put this in the footer (sort of like the bottom of Yahoo! pages) where all items are expanded and static.
So my major heading would be across the top (horizontal) and the sub items would be indented vertically below and always expanded. Is there a way to do this? Check out the bottom of the BlackBerry DEVCON 2010 site for an example:[URL]

would be written on the top, and its texts and images on the itemTemplate.Then, collection WINTER and its texts and images on the itemTemplate.And so on.P.S: I´m connecting the Listview visually thru SQLDataSource, not programatically.How can i do it ? On the layout template using a JOIN on the SQL Statement ?

I have a list box which is populated using a dictioanry. When I iterate throught the selected items using the following code, it always show only the first items as selected - even if the first item is not selected. Have you ever encountered this scenario? This problem occurs when I use dictionary for binding. On the other hand a generic list works fine.
private void PopulateListBox2()
{
List<string> subjectList = new List<string>();
subjectList.Add("Maths");
subjectList.Add("Science");
ListBox1.DataSource = subjectList;
ListBox1.DataBind();
}
Even it will work fine, if the values are unique. But in my scenario, the values are same; only key varies. The following works
private void PopulateListBox5()
{
Dictionary<string, string> resultDictionary = new Dictionary<string, string>();
resultDictionary.Add("Maths", "Lijo1");
resultDictionary.Add("Science", "Lijo2");
ListBox1.DataValueField = "Value";
ListBox1.DataTextField = "Key";
ListBox1.DataSource = resultDictionary;
ListBox1.DataBind();
}
The following code has the problem......................

I have a DevExpress ASPxRadioButtonList which does not have any data source for the items. When trying to assign the selected item the control doesnt have any items. I have spent hours looking at this as it is set up to similar controls which work fine.Here is my code:
ASPX:
<dxe:ASPxRadioButtonList ID="rblPriority" runat="server" Font-Size="11px" >
<Items>
<dxe:ListEditItem Text="Business Critical" Value="5" />[code]....
When trying to find the Item by value it returns null for the ListEditItem. The DataTable dt has a value for priority for 3 and the item should be in there as its hard coded in the ASPX.

I'm using a text book to teach myself ASP.NET 3.5. I'm using Visual Web Developer 2008 express to create my pages. At this point in my text, the author has me drag a DropDownList control to the Web page and then tells me to go to the Properies window and look at the Items property. I don't see an Items property. I've doublechecked that I'm on my DropDownList control, but I see no Items property. Is this a bug in VWD, an error in the book, or just plain old User error?
I'd be willing to hard-code the property in the source window, but I don't know the syntax. I tried
items="Vanilla, Chocolate" but nothing appears in the list when I view the screen.

I have a usercontrol on my page. The user control contains an ajax updatepanel with a listbox in it. There is also a PopupControlExtender that is tied to that panel so when the user clicks on something the popup shows. That is all working fine except when my page initially loads I briefly see all the listbox items and then they go away.

I have a number of products in a SQL2005 DB. I have the Stored Procedure set-up to return the info as grouped rows containing 'manufacturer, model, quantitiy'.
I need to then display this content on a c# Asp.Net 4 web form grouped by manufacturer with the manufacturer as the group header. The whole data should be displayed over a 3 column layout.
So, Ive used a Datalist as this allows for the number of columns to be stipulated.
However, I can't work out an effective way to show the various products groupd by manufacturer, eg as shown below;
Toshiba

I have a custom menu, which leverages the standard asp.net sitemap. It works well but some of my pages are dynamically generated by URL rewriter, so they don't sit in the sitemap XML file. At the moment I rolled a custom solution which shows/hides menu items via CSS class and a programmatic check of the role that the user is in. It works ok until I visit a dynamic page that doesn't exist in the sitemap file. I've tried the "roles" attribute in the sitemap file with security trimming but it isn't working because I have a custom menu.
Is there a way I could leverage the roles attribute in the sitemap file to show/hide menu items for my custom control below, even when some pages are not in the sitemap? My menu control is below...
<div class="menu">
<ul>
<asp:Repeater ID="rpt" runat="server" DataSourceID="smdsMenuPrimary"
EnableViewState="False">
<ItemTemplate>
<li class="<%#GetDisplayClass((SiteMapNode)Container.DataItem)%>"><a href='<%# ((SiteMapNode)Container.DataItem).Url %>'><%# ((SiteMapNode)Container.DataItem).Title %></a></li>
</ItemTemplate>
</asp:Repeater>
</ul>
