Web Forms :: Picking Random Items From A List Based On Percentages
Jun 10, 2010
I am trying to make a way so that I can have a group with items in it, each one of the items (which is an object in a list) having a double type value, the total of all the items in the group is 100 when you add up all their properties. The purpose of this is that there can be random selection of the items.
When a request comes in, I need to be able to pick 1 of these items at the rate of 25% so that after a while (more and more requests) that each of these gets very close to 25%. I have tried looking at random numbers but pulling a number back seems useless in this case because for example if a random number retrieved was the number 5.4, how would I send it to an item? I cannot keep a history of the item requests so that I can factor that in. I need to be able to pick a random number and over time have each of these 4 items be selected an equal amount of times, the percentages and amount of items is going to change constantly but the sum of all the percent properties within a group is 100%. What is the best way to accomplish this in C# with a web form?
I have a drop down that lists all our 40+ locations.. I then have a list box with all our locations as well. The client is presented with the question which locations have you worked at before. If they pick say 3 locations, i need to remove or disable those 3 from the drop down. I have other code for creating a drop down, but not sure where to go with this.
Is it possible to assign a colour to a drop down list item based on it's value?For example: I have a drop downlist where I've got a bunch of items that have integer
values. I would like to highlight the items with values in 1000s in grey.
I've boldified the items I'd like to be highlighted in grey ,For added complexity I need to highlight the items with values 1000 in a light shade of gray and items with values 2000 in a darker shade of grey. I'm using Web Developer, and C#
I've got a Gridview in which I have a column that shows percentages. I use the 0:P2 to format the percentage into readable format. However when the user 'edits' the particular row the percentage sign % still shows up in the textbox. When the user tries to save/update their change I throw an error on the % sign.
Is there a way to show the % only when the row isn't in an editable state?
I have use chart controller in my web application but it display wrong percentages this are the value: TOTAL COST : 75000000000.00 LOYALTY DISCOUNT : 7500000000.00
When it display on pie chart it display TOTAL COST :90.91% and LOYALTY DISCOUNT=9.09% but it should be 90% and 10 % how can I correct it chtSavingBrekDown.Series["Series1"].Points.AddXY("Total Cost", totalCost); chtSavingBrekDown.Series["Series1"].Points.AddXY("Discounted Dolers", discountValue); chtSavingBrekDown.Series["Series1"].ChartType = SeriesChartType.Pie;// Set the Pie width //chtSavingBrekDown.Series["Series1"]["PointWidth"] = "0.5";// Show data points labels chtSavingBrekDown.Series["Series1"].IsVisibleInLegend = true; chtSavingBrekDown.Series["Series1"].LegendText = "#AXISLABEL"; chtSavingBrekDown.Series["Series1"].Label = "#PERCENT"; chtSavingBrekDown.Series["Series1"]["BarLabelStyle"] = "Center";// Show chart as 3D chtSavingBrekDown.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;// Draw chart as 3D chtSavingBrekDown.Series["Series1"]["DrawingStyle"] = "Cylinder"; chtSavingBrekDown.Series["Series1"].Points[1].Color = System.Drawing.Color.Yellow; chtSavingBrekDown.Series["Series1"].Points[0].Color = System.Drawing.Color.Blue; chtSavingBrekDown.Series["Series1"].Points[1]["Exploded"] = "true"; chtSavingBrekDown.Legends[0].Enabled = true; chtSavingBrekDown.Titles[0].Text = "SAVING ESTIMATE BREAKDOWN";
I have a list box that allows for multiple selections (holding down the control key) the selection quantity is basically unlimited, but realistically should never be more than 50 to 100 items from the listing of about 3000 items.
I need to collect the list of selected items from the drop down list and retrieve each of their full records from the item master and populate a gridview.
I have a page in my site currently listing 20 featured items (actually venues). On my home page I display 3 of these. I would like these 3 to be totally random of the 20 from the other page. Can this be done just using div ids or something or do I need to put the data in a database to do this? If so where do I start in VWD Express?

I could really use some building the SQL statement to select the choosen record data. I think I have the selection list worked out by populating an array but I am not clear on how to build the SQL query.
I'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
i have over 100 items all loaded in a dropdown list. They all are assigned a value between 1-10 which represent 10 categories. When certain buttons are clicked, i want the dropdown list to display only items with a value "1" or "2", etc.
Is it possible to select values from a List, where the items contain in a different list aswell?for example;
[Code]....
What I need are all the items from the first list "Items", where the string contains something from the second list "List".So I need something which returns the first 3 items (which contain the term "Item") from the first list.
I hv created menu using sitemap xmldatasource now i want to display that based on Category or Roles. I have Created 4 Category in my sql Server 2005. when particular user logged in based on his Category menu nodes should display.
How can i generate dropdown lists based on what has been selected in the checckbox list. Below is an example of what i need. if the user selects the options day, lotID and waferID, then 3 cascading dropdown lists should be displayed. And then a gridview displays data based on what has been chosen in the dropdown lists.
Day LotID SlotID WaferID VendorID ToolID LocationDetected ProcessStep Stage Precipe WaferStartMaterial WaferStartVendor WaferStartLot WaferDiameterCOA WaferMapTitle BreakPoint BreakpointSide BreakpointMeasurement
I'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.
I need to bind my dropdownlist to my dataset that is returning application specific text values. But for purposes on that page, i need to assign the value to each one starting at 0 to the number of items returned from my dataset..
Example, if my dataset only returns 1 item, the value of that item needs to be 0
[Code]....
If my dataset returns 4 items, the value of those items needs to be 0 thru 3
[Code]....
Is it possible to assign values like that to a dropdownlist from the code behind?
