I have a listbox control data bound to a data source and I want to be able to get the value of each selected item so that I can use that information to form an insert query for another table. In other words be able to select a few items out of the returned list and get the selected value of each. I tried using a for each statement but came up with some strange numbers.
View 2 RepliesI have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load

View 4 RepliesI am using the cascading dropdownlist controls from the Ajax toolkit. I have everything working perfectly and all of my select changes work. I have 3 related select boxes that all work great for single item select. What I need is for my last dropdownlist to allow for the selection of multiple items. I have tried adding the 'multiple' attribute to the final dropdown list and it allows the selection of multiple items but I cannot get the items when I post back, just a single item.

I have a list with multiple selection enable, wen i do a loop in back end to see which items are selected it always just shows me the first one as selected only and everything else false.

I am attempting to load a page to edit previously saved info from a SQL2008R2 database. When a drop down index changes, it is supposed to load the existing data from a table. Most fields work OK, but drop down lists throw the error. The list is bound to a different database and table from the existing data that is to be edited (if that makes sense). So, when the data is called for editing, that comes from tableB. The drop down list is bound to a different data source, tableA. When the initial data entry was done, the item exists in the table, so I fail to see why this error is thrown. There are many dealing with this symptom, and I have tried many proposed solutions with no good result. Here's the code that retrieves the data and throws the error...
ASPX code:
Code:
Product Brand Name: <asp:DropDownList ID="product" runat="server" AppendDataBoundItems="True" DataSourceID="SqlDataSource19" DataTextField="Brandname" DataValueField="Brandname" AutoPostBack="true"><asp:ListItem> </asp:ListItem></asp:DropDownList>
The SQLDataSource19 is from tableA.
VB:
Protected Sub DropDownList6_SelectedIndexChanged(sender As Object, e As EventArgs) Handles DropDownList6.SelectedIndexChanged
Dim conn As New SqlConnection("Data Source=server;Initial Catalog=database;User ID=user;Password=password")
Dim cmd As New SqlCommand
Dim reader As SqlDataReader
[Code] ....
The data is bring called from tableB. The error is getting thrown on the product.selectedvalue line..I think I understand the problem, but I am not sure how to resolve it.
the dropdown list is showing data from database, but how to retrieve the selected value and store it in a session variable??
View 1 RepliesI am getting this error: "Cannot have multiple Items Selected in Dropdown", when I Edit the data.
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;
}

View 4 RepliesI 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 ?
