Web Forms :: How To Show Multiple Selected Items Of A Listbox

Jun 18, 2010

I had used listbox control with multiple selection mode. I stored id with comma delimiter in database.


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 ?

ListBox Selected Values To String?

Sep 24, 2010

I am developing a Webpage that gives the user selection criterial before running a report. There is a ListBox that I need to get the selected values from. It is obviously a multi select listbox.

I need to pass the selected values as a comma separated string to a parameter used in an SQL query of the ObjectDataSource for the report. I was hoping some how to get the selected items, and load their value into a string array and then use the join( stringArray , "," ) to get the selected values into a string to send as a parameter to my objectdatasource but I cant seem to figure this out.. Ideally if code worked my way I would want to do something like this: Declare StringArray for each selected item in Mylistbox Add selected value to StringArray Set parameter = join( StringArray , "," ) Obviously this is what I need syntax for.. I pretty much just need to know how to get a string array or all selected values.

Listbox Not Retaining Selected Values Between Postbacks

Jul 16, 2010

I have a Listbox getting populated when the page loads itself and also in postbacks. Some items are already selected in that listbox even when the page loads or postbacks. I have to select one or more items in that textbox in addition to the selected one.

Till this point, it works perfectly, but the problem is that when i click an "update" button to save the newly added items, then also the page postbacks and so the list box get populated again. This will loose the newly selected items and none of the newly selected items will be saved.

So what should i do in order not to loose the newly selected items when i click the "update" button.

Note:- I need to populate the listbox on postbacks also. So the population of that listbox on postbacks cannot be discarded.

C# - Listbox Persisting Multiple Selected Items?

Jul 29, 2010

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;
i = i + 1;

DataSource Controls :: Using Values Selected From A "check Box List' In A SQL Select Query?

Jul 5, 2010

I have a table called 'Customer' that contains customer information. One of the fields is named "CustomerType". Each record in the 'Customer' table will contain the value of either "C", "I", or "O".

I have a form that contains a "check box list" named "Type". There are 3 values in the "check box list". The values are "C", "I", and "O". The user can select one or more of these values. I have a button on the form named "btnRunQuery.

When the user clicks on the button "btnRunQuery" I want to exectute a query that selects the records contained in the "Customer" table where the value in the field "CustomerType" equal the values the user selected in the "check box list". Example: If the user selected "C" and "O", then I want the select query to select all records that contain either "C" or "O" in the field "CustomerType".

I assume that what I need to do is to capture the values that the user selected in the "check box list" and put them in a variable. Then I need to format the "Where" statement in the query and add a "Parameters.AddWithValue" command.
