I 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 ?

just want to have a quick question about the value of dropdownlist listitem. I have a gridview which has its datakey value linked to a dropdownlist. In the dropdownlist I have many listitems. So I decided to combine some list items together. Originally, the values of the items are 1,2,3,4,5,6,7,8. But I want to have only 5 items by combining 5,6,7,8 into one listitem called "Others." So if the listitem "Others" is selected, the gridview will show all the records that have value 5 or 6 or 7 or 8. Is it possible? How can that be done?
I hope I made myself clear. Any question, I am happy to clarify.
i did not know how to phrase the question above but this is what I want to achieve;

I have a custom list earthquakes which contains a list of earthquakes. How do I parse this in JavaScript in order to add it to innerHtml and display on the screen. The problem is that I cannot get this to display on the screen in a div. When it parses I get no result because my javascript is wrong and if I try just printing the result i get [Object object]
So the flow goes input from textbox -> web service -> list to javascript
earthquakes class:
public class earthquakes
{
public string eqid { get; set; }
public double magnitude { get; set; }
public double lng { get; set; }
public string source { get; set; }
public DateTime date { get; set; }
public int depth { get; set; }
public double lat { get; set; }
}
dataEarthquakes class
public class dataPostalCodes
{
public List<postalCodes> postalCodes { get; set; }
}
WebService:
public static dataEarthQuakes getEarthquakes(dataPostalCodes postalCodes)
{
double lat = postalCodes.postalCodes[0].lat;
double lng = postalCodes.postalCodes[0].lng;
Uri address = new Uri(String.Format(FindEarthquakes, lat, 0, lng, 0));
WebClient client = new WebClient();
string jsonResponse = string.Empty;
jsonResponse = client.DownloadString(address.AbsoluteUri);
var results = JsonConvert.DeserializeObject<dataEarthQuakes>(jsonResponse);
return results;
}
Javascript:
function OnLookupComplete(e) {
var result = e;
var weatherData = new Sys.StringBuilder();
var line;
for (var property in result.dataPostalCodes) {
line = String.format("<b>{0}:</b> {1}<br/>",
property, result.dataPostalCodes[property]);
weatherData.append(line);
}
$get('divResult').innerHTML = weatherData.toString();
}
Json string:

What I have is button that should open another page only if textbox length is 8. Javascript must be added from code because it does not simply calls the bla.aspx, it's more like bla.aspx?id=4&code=234 etc etc...
I have this code on server side
button.Attributes.Add("onclick","javascript:window.open(bla.aspx)");
on client side i have
<asp:TextBox ID="policyNumberTxt" runat="server" MaxLength="8" CausesValidation="true"></asp:TextBox>
<asp:RegularExpressionValidator ID="policyNumberTxtRev" runat="server"
ControlToValidate="policyNumberTxt" ErrorMessage="Length must be 8."
ValidationExpression="{.{8}.}" ValidationGroup="bla" Display="Dynamic"></asp:RegularExpressionValidator>
<asp:Button ID="printBtn" CssClass="button" Text="Print" runat="server" CausesValidation="true" ValidationGroup="bla" />
What happens is that when I click the button page bla.aspx opens, and even postback is trigered. Validator is showing the message, but page is opened and postback trigered.
How to handle this? Validation is broken...

I have a DropDownList inside the EditTemplateItem (if the user clicks edit) in a GridView.The DropDownList receives all available rows from the database. My problem is,if the user clicks Edit in the GridView to edit a row and opens the DropDownList Box the original item is not selected but the first one.That means the items are sorted. Have someone an idea how I can solve this issue that the right item / the original is selected if I change to edit mode of the grid view?

I have requiremet like in checkboxlist displaying all country names from database. The first item is 'All Countries' and country names will start from second item. So, when user click on All All Countries checkbox, all the remaing items should be uncheck and when user click on of the country checkbox then 'All Countries' should be uncheck like that. I googled sometime but got the articles which are explaning with a separate checkbox for check/uncheck items in checkboxlist. I don't want a separate checkbox......the All Countries checkbox should be first item of the checkboxlist.

So, for example, some of the individuals that exist in this table might no longer be associated with a specific department, institution or have data in the "Address2" column.
On my website, registered users can make a profile about themselves suchas name, Favoirite color, hobbies, etcI have a DataTable called User which hold this information.also there are other datatables for Hobbies and Colors which list all possible options.To let the user update their choices I have a FormView in Edit mode on the aspx page whichis binded to the UserTable with a GetProfileByUserId Method and objectdatasource.
Within the formview, i have added drop down lists that are binded to the hobbies and Colors tables so they can edit their previous selection.On clicking Uodate update formview calls an Update Method that adds new selections to the User databaseNow I have two questionsIs it possible to show in the dropdown list the selected value that the User has already made?If the user only changes hobbies and not colors when they click update will a null value be passed into the data table for colors that replaces their previous selection?
