I have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.
I have some dropdown list boxes that I need to fill with data from a database but I also need the first option to be "Show All"... So I need to combine using a datasource and manually adding an item to the top of the list. I have tried two different ways with no luck:
1. with the appendDataboundItems = true, on aspx page, and below code in codebehind:
I am using the cascading dropdownlist controls from the Ajax toolkit. I have everything working perfectly and all of my select changes work. I have 3 related select boxes that all work great for single item select. What I need is for my last dropdownlist to allow for the selection of multiple items. I have tried adding the 'multiple' attribute to the final dropdown list and it allows the selection of multiple items but I cannot get the items when I post back, just a single item.
Looping Through Checkbox List and adding selected items to MS SQL DatabaseI don't want to store it using comma deliminator.I will need to do a search on analyze which users have what music in common.The image above is from a tbl_lookup_music table I created. MusicID, MusicNow how should I build the logicIF we have a user that has a tbl_profile table. And listens to many different types of music. How should We store the data.------------------------------------------------------------------------------------------CREATE TABLE [dbo].[tbl_lookup_music]( [MusicID] [int] IDENTITY(1,1) NOT NULL, [Music] [nvarchar](64) NOT NULL, ---- Type of music. CONSTRAINT [PK_tbl_lookup_music] PRIMARY KEY CLUSTERED ( [MusicID] ASC )WITH(PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY----------------------------------------------------------------------------------------------CREATE TABLE [dbo].[tbl_Profile_Music]( [ProfileMusicID] [int] IDENTITY(1,1) NOT NULL, [ProfileID] [int] NOT NULL, [MusicID] [int] NOT NULL,PRIMARY KEY CLUSTERED ( [ProfileMusicID] ASC)WITH(PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]GOHow should I setup this table.
Does anyone know how to do this so when I select something the 1st dropdown and the 2nd one becomes visible and populates list from a Select statement. I really need help on how to do in an aspx and not on the code behind page.
I have a drop down list control populated with items and some code to take the currently selected item value. The problem is I only get the value of the first item in the list regardless of what item is actually selected. Here is my code to populate the drop down:
protected void displayCreateCategories() { StoreDataContext db = new StoreDataContext(); var a = from c in db.Categories orderby c.Name select new{catName= c.Name, catId=c.CategoryID}; ddlCategory.DataSource = a; ddlCategory.DataTextField = "catName"; ddlCategory.DataValueField = "catId"; ddlCategory.DataBind(); }
To get the value of the currently selected item which in my case is always of type integer I do label1.text=Convert.toInt32(ddlCategory.SelectedValue); I get the selected value, but it is always for the 1st item in the list. I'm pulling my hair out over this.
I have a situation where some dropdown listboxes contain some items, then there's a separator line, and then there are more items. The ones above the separator line reflect the "commonly used items". To better highlight these I was using code like this to individually color those specfic items:
foreach (ListItem item in ddList.Items) { if (item.Value == "-1") unAssigned = true; if (!unAssigned) item.Attributes.Add("style", "color:#5558ff"); }
This code works fine EXCEPT that once a PostBack occurs then the highlighting disappears. The items in the dropdown listbox remain (without repopulation) but not the highlighting.
I'm curious why this is happening and whether there's a way for the highlighting to "stick" short of calling this code from the Page_Load event handler every Postback?
how to access related columns in a dropdown list? In the example below I have a dropdown which is bound to a list of countries, I know how to access the text & value fields but how would I access data such as "Region"? I know I could do this by spinning through the list until CountryCode on the lsit and selected item match but wondered if there was a better way.
