With reference to : [URL] ....
No you cannot add a third parameter in the Dictionary. It contain Key Value pair data.But if you want to add third parameter then simply use DataTable and add these in the DataTable row.Name of Builder , Title Of Buidler , Builder ID
So how to acheive that task ? so far i did like this :
public void AddNewCMP(string PersonName , string PersonID , string PersonTitle) {
var dt = new DataTable();
if (ViewState["CMPDataTable"] != null) {
dt = (DataTable)ViewState["CMPDataTable"];
[Code] ....

I am using C# ASP .NET 2.0. I have a web form with two DropDownList controls. In my code behind I get data from a DataSet. One column is a string (Month), and another is an integer (StatusID). I am setting the selected item in the each DDL in the code behind by doing this:
[Code]....
I have a button with a Click event. What I want to do in the click event is be able to check if the currently selected item in each DDL (if the end-user changed the selection) is different from what was selected in the above code.
protected void DDLzone1_SelectedIndexChanged(object sender, EventArgs e)
{
BindDistrict();
}
[Code]......
here when i click on ALL item from ddlzone1 it just "ALL" item in ddldistrict
i want when i select "ALL" item from ddlzone1 in ddldistrict14 show all data from database
below is the code I have but I want to change the ddl.Deal(dropdownlist) to cbl.Deal(checkboxlist).. How can I loop throught each items if checked. and if all items are checked. to filter my data and show in gridview..
protected void btn_Click(object sender, EventArgs e)
{

I am getting this error: "Cannot have multiple Items Selected in Dropdown", when I Edit the data.
i'm using sql server as my database.How to make the items in dropdownlist to change when the a radiobutton is selected?
i've two radiobutton;
Food and Beverage; which belong to the group named: Category
when i select the beverage radiobutton, the dropdownlist will have the
items from the database that belong to the beverage.and for food too.
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 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 ?

View 1 Repliesi want to apply color to selected number of items in checkbox list and seleted number of items in drop downlist for e.g color red for few items and black (default). I have a bit value set in data base so if bit is set to 0 then red and if 1 then back.
View 5 RepliesIm using Visual Web Developer 2008 and I have set up a gridview showing data from a sql database, it shows 3 columns, these are: item name, item cost and a check box column to allow the user to select certain items. I would like to have a text box that shows the sum of all the selected item costs.
Im coding in VB.
1)I want to iterate thourhg listbox and want to get the value of the items that are selected by user. Listbox is set to multiple selection.
2) is there a direct way to count the number of items that are selected?
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 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;
}
