Web Forms :: WebParts - Populate Form Immediately After ListBox Binded?
Feb 3, 2010
The user has to select from the ListBox to populate the DataGrid control. However, the Default value in the ListBox does not cause the DataGrid to be populated. Why is this?
I need to populate a listbox programmatically from 1 of 2 tables, depending upon user inputs at run time and I need to know how many rows to read. Otherwise, I get an exception error when I try to read data that does not exist after all rows have been read.
I have a listbox which I need to populate with the results from a stored procedure. I have a class Ethics and I can call my stored proc there but I don't know how to populate the listBox from this point on. Here's what I have so far:
I want to bind list item with selected value only, like i saved selected values of list item in Database as 1,5,8,9 in database.
Now in case of edit i want to fill list item with samevalues and select only those whose value i saved in database.
Try Dim VerticaID As String For Each item As ListItem In lstItem.Items If item.Selected Then VerticaID += item.Value + "," End If Next VerticaID = VerticaID.Substring(0, VerticaID.Length - 1)
Hey what i am trying to do is i have a listbox with some simple values in it
1 2 3
and what i want to do is add a value that has multiple values to it...for instance i want a value = All DEV which will represent many values in itself so that once ALL DEV is selected it actually has many different numbers assigned to it. Can this be done? I understand that the value 1 has just one value behind it, same as 2 and 3 but I want the All DEV one to have multiple values behind it such as 5,6,7,8 for clicking just the ALL DEV selection.
From the asp.net page, I would like to view the reporting services reports i.e. the .rdl files.I am using a reportviewer to access one of the reports as follows. Notice that I have hardcoded the name of the .rdl report.
Question:There are several reports. The names are stored in a table in the database. Do you know how I can populate a listbox with the names of the reports but do not know how to show the selected report in the viewer. Notice that at present I am hardcoding just one name and not sure how to be able to show the selected report
how to populate a drop down listbox (dlName) from a web service with last and first name i.e. (LastName, FirstName). My Web Service XML that I am requesting is as follows:
I have been trying to populate either a listbox, dropdownlist, or textarea with a large amount of numbers. I can create the list by manually putting in the numbers I want but that is not what I really want to do. There are too many numbers anyway. Is there a way to use maybe an array and a for next loop to put many numbers in a list where you can scroll down and see each item entry.
I am trying to retrieve multiple values from the session variable in which I stored the values as List. Here's the code I applied but this gives me only the lst value from the list in the output.
Array k= yourlist.ToArray(); for (Int32 i = 0; i < k.Length; i++) { Int32 x = Convert.ToInt32(k.GetValue(i)); SqlCommand cmd2 = new SqlCommand("select id,name from plugins where id =" + x, con); SqlDataReader dr2 = cmd2.ExecuteReader(); if (dr2.HasRows) { while (dr.Read()) { ListBox2.DataSource = dr2; ListBox2.DataBind(); } } dr2.Close(); cmd2.Dispose(); }
Lets say I have ListBox1 (1,2,3,4,5,6) and a ListBox2 (A,B,C,D,E,F)..
and a Button and a GridView. Now when I click the Button. I want a GridView Column 0 to be populated by ListBox1 and Column 1 to be populated by ListBox2. . C# / Asp.net.
I have a form and if the user checks a box or clicks a certain item in the listbox, I need a new form to be generated, with a certain form name in the same format, and the prior form to be locked for editing.
this should be pretty simple but I can't find a solution. I spent a bunch of time, without luck, searching for an answer that makes sense (to me). Here is the problem. I have an asp form in a frame (I know frames are considered evil, but this part is non-negotiable) This form has an asp:listbox that is tied to a SqlDataSource. A button on this form opens a second form that allows the user to add records to the SQL table that is bound to the SqlDataSource object (the source of the listbox in the first form) The thing is, that when the user closes the second form and returns to the first, the list box needs to be refreshed and I have no idea how to do that.
My forst post here + I am new to Asp.Net as well. 2nd my apologies if this question has been asked before.
Here is my problem. I am given some really abstract ASP.net pages, where I have to make a change. My change involves adding some links and on each link I have a function which is triggered when link is clicked on. This function validates some information in the form and then submits this form. This same form contains mulitple list boxes, all of them has AutoPostBack=true. The problem is when I select an item from listbox the form is submitted as I can print all the form properies on the page(all fields with their names and values) however, when I click on link and call the same forms submit(); method I dont see that happening. none of the form fields are printed out.
Now once I click on listbox and select an item after that as long as that item is selected, I can click on all links and they all call the submit() method of the form and it produces required resutls. I am really baffled as this doesnt seem correct as far as simple html is concerend.
i have been trying to solve this issue for over a month and i tried many different things
i want my shopping cart list box to have items in it then I save all of those items in a session variable. I pull that session out on my checkboxlist page and I want it to autocheck all the items that were in my previous listbox that are now in the session
I also want to to this the other way so I can check a new item in my checkboxlist and I want it to automatically put the item in the listbox The issues I have been getting is a ListItem error or a List<Product> Error it does not work no matter what ways I try it
I need to populate my textfields from values in database. I also need navigation buttons to scroll through all records, similar to an access form. Below is what I have on the OnLoad event:
What I need to do is when the data submits redirect the user to a page where they can download a personalised certificate in either PDF or word, which has been partly populated by the data entered in the web form.
New at SQL and ASP.NET C#, bear with me. I have a form to insert into mulitple tables of a sql db. The form includes two listbox's, categoryIDlistbox and subcategoryIDlistbox, both with the ability to select multiple choices. Idea is that there is one record for the user created (Table1) and then that user can have multiple categories and subcategories assign to him/her in Table2
Table1: userID fname lname etc...
Table2 userID categoryID subcategoryID
If I understand correctly I need to use an array to take the multiple listbox items and save them to the tables. Not sure where the array goes in my code behind page to process the listbox and loop for muliplte selections. Here's my current code behind, where do I place the listbox array?
