I have two dropdowns in the footertemplate of my gridview inside a usercontrol.
I also have a button "btnADD" inside the footer template. I am using the footertemplate to add a new row to the grid.
What do I do to validate on Button_click event for 'btnAdd' if a value is selected in the dropdown other than "select.." which I dynamically add in rowdatabound event?
I have this javascript function that I wanted to implement, but it gets called in the Page_load event rather than the button click event and gives an error.
The javascript function that I need to call is this: ( I created a method to return a string to use it in regards to RegisterClientScriptBlock, but do not know exactly how to use it)
rotected string BuildValidation()
{
StringBuilder sb = new StringBuilder();
sb.Append("<script type='text/javascript'>");
sb.Append("function ValidateWComp() {");

I'm following along with Nerddinner making a few changes, and can't figure out why my Create form is not validating. I'm using Linq to SQL and trying to use Modelbinding to map my form data automatically. Using the code below, I do not receive any validation errors on the page, but can't make it past my try{} block. When unhandled, the error I receive tells me I'm unable to insert a Null value for "basetype". This is correct based on Database constraints, but why am I receiving exceptions, and not the nice red error messages and validation?

I am struggling to create a webservice method using LINQ technology and to populate a dropdown in a form. Here is the Webservice code.
[WebMethod]
public
string[] GetAllCountries()
{
LinqClassesDataContext db =
new
LinqClassesDataContext();
var q =
from c
in db.ListContinents()select
c;
return q.ToList() ;
}
And here is the form code behind
protectedvoid
Page_Load(object sender,
EventArgs e)
{
WSClass WS =
new
WSClass();//bool
ds = WS.GetAllCountries();
var v = WS.GetAllCountries();
ddlContinent.DataSource = v;
ddlContinent.DataBind();
}

I have a grid bound to a linqed SP thus:
Session["results"] = db.spGetCaseByNumberOrSurname(txtCaseNum.Text.Trim(), null).ToList();
gvResults.DataSource = Session["results"];
on the sorting of it, i would like to be able to do this..
protected void gvResults_Sorting(object sender, GridViewSortEventArgs e)
{
string sortExpression = e.SortExpression;
List<spGetCaseByNumberOrSurnameResult> data = Session["results"] as List<spGetCaseByNumberOrSurnameResult>;
if (sd == SortDirection.Ascending)
{
sd = SortDirection.Descending;
gvResults.DataSource = data.OrderBy(d => d.GetType().GetProperty(sortExpression));
}
else
{
sd = SortDirection.Ascending;
gvResults.DataSource = data.OrderByDescending(d => d.GetType().GetProperty(sortExpression));
}
gvResults.DataBind();
}
sadly that doesnt do any sorting at all..it in fact errors with "The data source does not support server-side data paging."

I have a bound dropdown list populated with a table of names through a select, and databinding. it shoots selectedindexchanged that (through a postback) updates a certain gridview.What happens is, since it runs from changing the index, the one that always comes selected (alexander) can only me chosen if you choose another one, then choose alexander. poor alexander.What I want is to put a blanc option at the beginning (default) and (if possible) a option as second.I can't add this option manually, since the binding wipes whatever was in the dropdown list and puts the content of the datasource.

I have added a partial class to one generated by the Entity Framework. I wanted to add a calculated field that I could bind to my GridView. However, when I try to access the new property, I get an error message that this is a limitation to Entity Framework.Are there any work arounds to accomplish this?

I've tried to wrap up my problem with a complete example below - the original problem is part of a jQuery plug-in that I'm writing to extend the behaviour of an ASP.NET ajax application I already have.
The aspx page below has one drop down list which is marked for auto post back. I've also bound a change event using jquery (which ultimately I will swap for a .live() event to maintain the binding after the update panel refresh.) The problem is, when the jQuery event is bound I see two ajax begin requests and page_loads fire but only one ddlTest_OnselectedIndexChanged event. One of the page loads is malformed too - the content-length states it's about 300 bytes long whilst the totalBytes is 0 and form data empty. This does not happen if I bind to the click event of a button.
why the erroneous page_load event is firing ?

I have a small issue binding the values into a dropdown using LINQ in ASP.NET code-behind.
var clientquer = from i in Entity.New_Bank select i;
//var q = (from s in names
// select s).Distinct();
// var getlendername = (from db in mortgageentity.New_Lender group db by db.Bank_Name into t select t.Key).ToList();
if (clientquer.Count() > 0)
{
ddlbankname.DataSource = clientquer.ToList();
ddlbankname.DataValueField = "Bank_ID2";
ddlbankname.DataTextField = "Bank_Name";
ddlbankname.DataBind();
}
It is binding with duplicate values, but I don't want bind duplicate values. I'm trying to solve this by using a group by clause, but it is not working.

The file is situated in the App_Code folder and NOT as code behind. [Code]....
I would like to know how i can make populate my second Dropdown list with results. At this point it's just putting in the complete ProductSubCategory.

I'm new to Linq. I have searched and searched the web for a soluion, and can't find anything. I have a Linq query and I want to insert a row ("Select User") to the top before I pass it to the drop down list. I've been trying to use the Union but to now avail (it keeps telling me that my object doesn't support the Union method). My code, prior to attempting to inser a row, is very simple.
public SelectList DropDown_Users()
{
var context = new VivarianDataContext();
var query = from t in context.AspnetUsers
select new { t.UserId, t.LastName };
list = new SelectList(query.AsEnumerable(), "UserId", "LastName");
return list;
}
Now I try to insert a row and I found this on the internet and it seems to say that his solution will work. But it is filled with syntax errors. [URL]
I tried to implement it using the following code, but it doesn't compile.
public SelectList DropDown_Users()
{
SelectList list;
//get the original data
var context = new SQL2005633131VivarianDataContext();
var query = from t in context.AspnetUsers
select new { t.UserId, t.LastName };
//create a dummy table with an empty row
var AllUsers = new List<AspnetUsers>();
var BlankUser = new AspnetUsers()
{UserId=System.Guid.Empty, LastName="Select One"};
AllUsers.Add(BlankUser);
//use Union to join the data - ERRORS HERE
var newTable = AllUsers.Union(query);
list = new SelectList(newTable.AsEnumerable(), "UserId", "LastName");
return list;
}

I can't seem to get any sort of validator to fire when validating my DropDownList. I just want to make sure that it isn't left at "--Select--" when the user presses the Add button on the page. I've tried a range validator and required field validator and neither seem to fire at all. My DropDownList contains ID which is an int that is hidden and Name which is a string that is displayed. The ID is -1 for "--Select--". I use these all the time and can't understand why the page in this new solution is any different from other solutions I have done in the past. What have I missed?
