How To Populate A Listbox In C# With Values From A Grid
Apr 9, 2010
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.
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(); }
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)
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 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 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.
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 Parent/Child Grid (also called Nested Grids).
Parent Grid (PG) :: PG has two template fields. 1st template field has "Category ID" and 2nd template has Child Grid
Child Grid (CG) :: CG is populated in PG's RowDataBund event based on "Category ID". In CG's DataBound event, I am doing something which I need to display in CG's footer row.
Problem :: In the footer row of each CG, I have to show the "Category ID" which is in PG' row. How can I get hold of the PG's row which hascurrent nested grid (there will 'n' child grids, one for each 'Category ID' in the PG ) so I can read the "Category ID"
I was thinking if I could do something (DataBound event of CG) like this..
string catId = ChildGrid.Parent[get the index of the current row in PG].Cells[0].Text;
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:
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 have a two Grid where I have to display some records from the table. The table consists of employee names ,manager names and their comments. Now on the first gird I am fetching data of employee names. Now on the second grid I have to display data of manager names and their comments. The data is on the same table. On show button of the first grid it shows all the employees. then on AdvWebGrid.ClickLink or any selected user on the first grid , i have to display the manager names and their comments on the second grid. How can I do that ?
This is the first time I have played with the web part of Visual Studio and I would like to know how to:
1) When A user selects a date from the calendar it will populate the grid with available classes. (I have already setup the query however I don't know how to execute it using the text from Label1).
See picture, "Label1" will show the date from the selected date on calendar, from there I want the label to populate the Grid with available classes.
I have a grid which displays a set of columns and I m trying to display only those rows in grid based on the options chosen or searched.
I filter options are
1) search for (textbox) - search from (listbox with columns product, product id , userid )
2) Date filter - choose 1 checkbox out of 3 checkboxes(create Date, submit date, Approve ) and whateevr is selected for the criteria we choose between date from and to calender.
3) Status - listbox with status ID 's Basec on this three filter options I need to frame a LINQ to SQL query that gives me results in grid any option can either be choosen or can be left blank I am using 3 - tier architecture and passing all this fields as parameters in a method from UI.cs to UI.DAL where I am writing a query to generate grid view rows. I think I need to use Dynamic LInq and I have not done that before !!
I'm adding ListItems to a ListBox from two controls, both are DropDownLists. The ListItem has the properties ListItem.SelectedItem and ListItem.SelectedValue, but I also want the ListBox to keep track of which DropDownList the ListItem came from.What would be the best way to do this?

I have some files listed on a listbox and want to upload them to the server. The values doesn't need to be selected. But I can't even get it working. Below is my source code:
I'm currently trying to move through all the values added to a listbox by the user, however, I want to retrieve the actual value of each item in the listbox and not the text.
I've gotten so far with the code below, but that only gets the text and not the value.
[code]....
How would I go about getting the value for each item in the collection?
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
