Using MVC 2 and VS 2010 RC.I have a varchar database column set to NOT NULL and I use the Entity Framework to bind the column to a textbox. I want a user to be able to leave the textbox blank and have an empty string inserted into the database column. However, MVC is trying to set the property to null during the Create postback, which causes ModelState.IsValid to be false and subsequently the validation UI is triggered with the message "The value '' is invalid".Here is the model:
[Code]....
The controller:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Candidate c )
{
if (ModelState.IsValid) // This is false when the textbox is left blank.
[code]...
I know that you can use exclamation sign to bind array of simple types (like string) to GridView like this
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Array Field" DataField="!" />
</Columns>
</asp:GridView>
But this doesn't seem to be the case with DataNavigateUrlFields
<asp:HyperLinkField DataNavigateUrlFields="!" DataNavigateUrlFormatString="RoleInformation.aspx?role={0}" Text="Manage users" />
and I get following error:A field or property with the name '!' was not found on the selected data source.
I have gridview with two column. Id and number. Id begin 1 continue till 300.
Id Number
1 2
2 1
3 4
4 5
5 3
6 2
7 5
8 3
9 1
10 1
11 2
13 2
14 5
But I want insert id and number from gridview into TableNumber like this:
If id in( 1 , 9) then add three space before number .
If id in( 10 ,9 9) then add two space before number .
If id in( 100, 999) then add one space before number .
For example:
" 1"
" 2"
" 3"
" 4"
" 5"
" 6"
" 7"
" 8"
" 9"
" 10"
" 11"
" 100"
" 101"
How I can solve this?

I have 2 dropdown lists on a WebForm. One of them is populated in the page's Page_Load event. This oneworks fine with the following code.
[Code]....
Then, after a value is selected from this list and a date is selected from a DateTime picker, then I click a button which is supposed to populate the 2nd dropdownlist. In the debugger in the button's click event I can see that the dataset is being populated with data, but then the list is never populated after the DataBind() method is run. Here is code from the button's click event.

How do I bind a result from a JSON string to a dropdownlist (I have 2 fields), "NAAM" should be DataTextField and "CODE" should be the DataValueField. Using ddl.Items.Add doesn't do the trick.
string:
{"NAAM":["Drenthe","Flevoland","Friesland","Gelderland","Groningen","Limburg","Noord Brabant","Noord Holland","Overijssel","Utrecht","Zeeland","Zuid Holland"],"CODE":["D","X","B","G","A","K","P","L","E","M","S","H"]}

i am loading xml file from url and storing data into my database.i am binding that data with my dropdownlist bt the problem is wheneverr i select any option from ddl...by defaulst it takes the always takes first selected index...i.e value at the zeroth index value.....i really don't know what exactly the problem either the problem is with dropdown or the way i am loading xml file and binding it to dropdown.....below is my cs code.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)

I'm using an edittemplate to handle both editing and inserting for a Formview. In Insert mode, the Identity parameter is not needed (and cannot be used in the parameter list). In Edit mode, I need the bound value to know which record to update. So, what I tried to do is set the Text property in the OnDataBinding method.
[Code]....
The result is that the field is bound for Insert anyway, shows up as a parameter, and my insert statement fails (since this extra field messes up the field order of the parameters). Plus, it is always null in Insert mode by definition.
Is the OnDataBinding method too late to clear the property? If so, where can I do this, since PageLoad is too early (the template has not loaded yet and I cannot Findcontrol the field. Or is there a better way to handle all this?
i'm writing a stored proc and if a field i return is longer then 200 characters, i want to truncate, find the last space, remove any characters after that space, then add some full stopseg:
INSERT INTO @rec(articleid, abstract)
SELECT a.id,
CASE
[code]...
private void AddDBDataToControl(DataSet app_Support,int count) {
int i = 0; while (count != 0) {
DateTime dt = Convert.ToDateTime(app_Support.Tables[0].Rows[i]["FromDate"].ToString());
//dt=23/08/2010 10:04:00 AM
DropDownList h1 = (DropDownList)GVDate.Rows[i].Cells[1].FindControl("txthour");
h1.SelectedValue = dt.Hour.ToString();
DropDownList m1 = (DropDownList)GVDate.Rows[i].Cells[2].FindControl("txtmin");
m1.SelectedValue = dt.Minute.ToString();
DropDownList h2 = (DropDownList)GVDate.Rows[i].Cells[5].FindControl("txthourto");
DateTime dt2 = Convert.ToDateTime(app_Support.Tables[0].Rows[i]["ToDate"].ToString());
//dt2=28/08/2010 14:25:00 PM
h2.SelectedValue = dt2.Hour.ToString();
DropDownList m2 = (DropDownList)GVDate.Rows[i].Cells[6].FindControl("txtminto");
m2.SelectedValue = dt2.Minute.ToString();
count--; i++; } }
When the function executes
h1.SelectedValue = "10";
and
m1.SelectedValue ="04";
but when it reaches to
count--
h1.SelectedValue takes the value "14"; rather than h1.SelectedValue = "10"; and
h2.SelectedValue = "14";
and
m1.SelectedValue ="25"; rather than m1.SelectedValue ="04"; and
m2.SelectedValue = "25"
So here is the problem , Is it possible to get the "SelectedItem.Text" of a binded dropdownlist? because everytime I'm getting null Even though I'm having
items in the dropdownlist.
I'm getting the items that I want in the dropdownlist but I can't find out which one is selected.
[Code]....
here is my aspx code:
[Code]....
[Code]....
My Default Page
[Code]....
when it goes to databind it gives me error asDropDownList1 do not contain binding with ID
I have an array in my code behind page. say:
int[] Hour = new int[24];
I also have a dropdownlist on my aspx page. say:
<asp:dropdownlist id="ddlHour" runat="server">
I want to bind the value of array to the dropdownlist such that when I dropdown the list, I get to see the values from 0 to 24.
I have two tables. t1 and t2
t1 is related to t2 through Order Numbers
these order numbers in table t2 have many part numbers(and hence the need for a second table t2)
I can display t1 using gridview just fine
In that same gridview iI have added a template column containing a dropdownlist(to show partnumbers)
now how can I bind this dropdownlist to the order number so that when the page is loaded the user can click on the dropdownlist to see all the partnumbers associated with that order number.
i have 2 page
1-index.aspx
2-state .aspx
when users click on menubar in index.aspx they go to state.aspx in State.aspx is gridview with 6 Dropdownlist that occording to their selected item from DDL they can see result in gridview
now my problem is :
when i click item from menubar in index.aspx when it go to state.aspx it doesn't show any thing in gridview.
i want at first when users go to state.aspx page they can see all data in gridview after that they select item from DDL and see result according to their selected item
