Suppose I have a list of a couple of thousand organizations and a user needs to be able to select one of them. The list is too large to populate in a dropdown at page load, and the user often knows what they want but it's not the first part of the organization name. That is, they know "Collections" but not that the precise name of the organization is "Department of Collections". So the user will need/want to type in some information.
It's easy enough to use an autocompleting textbox of some kind, but I don't want to allow the user to type in random text - they have to choose one of the organizations explicitly.
I am trying to set the item that is selected from a drop down list based on what it in the database for that particular record. I am filling the dropdown list with a SQL DataSource I have tried a couple of example that I have found for selecting the item in the list but I am always getting the first item in the list as the selected item. This is what I am currently working with:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
i have used one drop down list box...in that ....whn i m running web applicaiton i need to stick the value which i m selected for the movement upto i select the next choice. it is always going to the first value always. i have 40 items in my drop down. whn i select the 5TH item after selecting 5th item it going to first item.
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 inherited an application written for VB.Net and am converting it over to ASP.Net, with VB as the back end. I have a data pull that adds values to a new instance of a class, then adds the item to a listbox. It worked great in the VB.Net version, but I get the following error in the Visual Studio Text Editor when I try to use the code:
Overload resolution failed because no accessible 'Add' can be called with these arguments:
'Public Sub Add(Item As System.Web.UI.WebControls.ListItem)':Value of type 'MyItem' cannot be converted to System.Web.UI.WebControls.ListItem'. 'Public Sub Add(Item as String)':Value of type 'MyItem' cannot be converted to String.
I have played around with the code quite a bit and have been researching online, but I'm just drawing a blank here.
I put the class("MyItem") in the "App_Code" folder in a file called "MyItem.vb". The class code is as follows:
The code I have for the sub that is supposed to add the items to the listbox is as follows:
I'm trying to built in my web site the possibility to loud equal fields in the "select" page(when the user select item , I would like items that are related data in the "name column"ill be fire hopefully I'm clear That I have tried doing was in my repository I have written:
I have a form where i want to view all columns from a table.I have a textbox and differeent radio button having values of each column.On click of button.I want to view all the columns as per selected row/rows from value given
I have a drop down box with values that shows on loadUnited States Canada Now I have a function that is checking the users value from the database which is fired on a button click. What I plan on doing is comparing the string like if United States(db value) == United States (dropdown value) then go ahead and select United States in the drop down. When I do this I am getting the right value selected but it is making all the values the same for all records.
i am using a treeview control in my master page to act like a menu.it has different nodes levels e.g. root, parent and left.when i click an item from the tree view - i am taken to the page - but the tree view goes to its orginal state of being collapsed rather than keeping its state of nodes that have been expanded.does anyone know how i can maintain the state of the tree view in the master page
May be I'm trying to run before I can walk, but here goes, I find coding for ASP so frustrating it's just not logical JIM!Anyways after my rant, as I'm a huge fan of the listview control in WinForms I'm trying to get the hang of it in ASP, wth not much luck so far.
For some reason, I get an error half way through cycling through my items in a listview right before a record that has a null value for one of its items. It doesnt' haappen any other time. It happens after completing one cycle of the onItemDatabound eventfor a record in a row that is immediately before a particular null value in record immediatley following.My code is written to look for the proper edititemindex, and if it sees it, then it checks for null values for all the items. I can't even get that far, it errors just before the onItemDatabound even runs for the correc edit index
I have a GridView control that contians, among other things, a DropDownList. In this particular case, the DropDownList is in the EmptyDataTemplate, but I suspect I will run into a similar situation when I'm in Data Rows as well.I'm trying to handle the OnSelectedIndexChanged event for the DropDownList and in the .aspx file I have used the declarative syntax to assign the handler OnSelectedIndexChanged="ddlStoreList_SelectedIndexChanged") and have created the handler code to deal with this.
The problem that I'm running into is that the event is not being handled. In other words, when I put a breakpoint in the handler, I find that it is not getting hit when I change the selection of the DropDownList.
