Forms Data Controls :: Insert Multiple Items From A ListBox?
May 8, 2010
I have two ListBoxes. I can move items from one list box to the other. I have an Insertcommand for inserting added values from the "ActivePrograms" list box to a db.
my problem is that it inserts only one item when sometimes the user added multiple items.
how do I insert all existing items from "ActivePrograms" list box?:
second issue: how do I make sure the insert command go through the list of items in the listbox and makes sure these rows does mot already exsited in the db? in other words insert only NEW values for that 'Id' value
I have a listbox inside a formview in a details page(master/details). The values for the listbox will come from a lookup table and when the user select one or more values it should be inserted in a table. The process sould be like the following:
The user will select one or multiple values and click on a Select button. Then a label should show the selected values. Then the user will click on the Insert button in the formview to insert it in the database.
i am devalope one webpage it contain one textbox and two listboxes in that user can enter textbox value and select multipule selected values fromlistbox in that how to store database values into one record (i.e database contain 3cloumns in that store in column1:20(textbox value) and clomun2:4,3,5(selected listbox values ) and column3:4,5(selected listbox values)).in that i am using wcf service for inserting method how to pass multipule selected values into services in c
I'm trying to populate 1000 ListItems in a ListBox.
how to do it. Currently only 100 items are being displayed even though I set the capacity of the ListBox to 1000.
Below is sort of how my code looks like. :)
listBox.Items.Capacity = 1000; foreach(entity ent in enitityCollection) { ListItem listItem = new ListItem(); listItem.Value = ent.Id.ToString(); listItem.Text = ent.Name; listBox.Items.Add(listItem); } entityCollection has 989 records in it.
Code does not generate any error. only that at the end of the loop I only get 100 items mapped to my ListBox.
I have a dataTable that contains a specific column from a database. A listbox contains 100 list items in it. When page loads, I need those listbox items to be selected, whose value matches the value in the datacolumn of the datatable.
Following is the code i tried, but is not working. For some reason, it selects only the last item in the datacolumn.
if (datTableRelatedSchool.Rows.Count == 0) { } else { foreach (DataRow row in datTableRelatedSchool.Rows) { foreach (DataColumn myCol in datTableRelatedSchool.Columns) { lstRelatedSchool.SelectedValue = row["RelatedSchoolPK"].ToString(); } } }
I'm using a listbox to save multiple selected value in db. I'm saving that values by seperating comma(,). In edit option i want to reterive the same value from db and want show multiple selected items in listbox.
I had used listbox control with multiple selection mode. I stored id with comma delimiter in database.
e.g.
1. List Item One. 2. List Item Two. 3. List Item Three. 4. List Item Four. 5. List Item Five. 6. List Item Six.
Suppose user select item 2, 4 & 6. So I will store it as a 2,4,6 in database. This will work fine.
Now in editing I have to shows selection-bar for item 2, item 4 & item 6. So I had typed below source.
string strData ="2,4,6" if(strData != null) { char[] separator = new char[] { ',' }; string[] strSplitArr = strData.Split(separator); int x = 0; for (x = 0; x < strSplitArr.Length; x++) { // lstWDef_PurchasesEdit.Items[x].Selected = true; lstWDef_PurchasesEdit.SelectedValue = strSplitArr[x].ToString(); } }
But with this statement I got only last item id as a selected item with selectionbar. In our example 2,4,6 only item whoseid is 5 got as a selected item.
if i use
for (x = 0; x < strSplitArr.Length; x++) { if (lstWDef_PurchasesEdit.Items[x].Value == strSplitArr[x]) { lstWDef_PurchasesEdit.Items[x].Selected = true; } }
if the selected items are serial like 2,3,4 then it is displaying correctly..
if items are 2,4,6 then it is not selecting the items of listbox properly.
Is anybody guide me how to make item 2, item 4, item 5 as a selected item ?
I have two databound listboxes. The first only shows items that have been assigned to my product. The second listbox shows all available items. What I want to do is select all of the items in listbox 2 that list box one contains.
I am persisting the search selection criteria of a listbox onto another page which is called AreasLb. Multiple areas can be selected, I simply want to set the listbox items that the user selected as .Selected = true
I think the below code should work, but it doesn't, with no items in the Listbox being selected.
if (s == "Areas") { string[] area = nv[s].Substring(0, (nv[s].Length - 1)).Split(';'); int i = 0; foreach (ListItem item in AreasLb.Items) { foreach (var s1 in area) { if (s1 == item.Value) { AreasLb.Items[i].Selected = true; } continue; } i = i + 1; } continue; }
I need to have a combo box like this [URL] Upon clicking the dropdown items width should be automatically increased to fully accomodate them. At present, it seems, ASP.Net combo box not supporting this ... I tried applying width attribute using Style.Add to each item.
I am working on a screen where in it has a typical 2 listboxes & 2 buttons(add/remove), so when these buttons are clicked the items have to move from one listbox to another. its all working fine with javascript.but the issue is, I am not able to get the items of the 2nd listbox in the codebehind. I tried with html & asp.net listbox controls. I even tried to access the listbox using Request.Form["ControlName"] - which gives a null value.In the listbox1 the data's are coming from database.The data's choose from listbox1 will be moved to listbox2. And again i have to update this data to one of database table.
what I am trying to do is: insert multiple selected items from CheckBoxList into DB
I tried using (foreach) as:
foreach (ListItem item in bookingid.Items) { if (item.Selected == true) { using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con"].ConnectionString)) { con.Open(); SqlCommand cmd2 = new SqlCommand("") }}}
But it only adds the first selected item .. What Should i do ?
i am making use of two listboxes. the data from one listbox is transfered to other listbox on button click, bt teh the data which is selected must be added to the table in the sql server. but it is not storing values it is throwing execption...

I have grid view in ASP.Net 3.5. I need to add multiple blank rows in a gridview and then have to save them in database. How can I do that in most simplest way?
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?
Is it possible to have 2 ListBox then when a Button is Click the Items is Sorted already to GridView accordingly. btw I have done a sort button but for LB1 only. and LB2 only.
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 scenario in which I want to display Multiple Columns in ListBox. I am working in .NET 1.1I am binding data to ListBox from DataTable. Example: I have Two Columns in Table ID, Name. So I want to display ID and Name in a Single LISTBOX.
