I am using a dropdown list in gridview and populating it from database.However ,i am getting "object reference not set to an instance ..." error even though i have reference.I have two more similar drop down list and they are working perfectly.
I am uploading the options for the dropdownlist from a "tab delimited" text file for all the dropdown list.I am not getting where exactly the problem is.
<asp:TemplateField HeaderText="Property" HeaderStyle-Wrap="false">
<ItemTemplate>
<asp:Label ID="lblProperty" runat="server" Text='<%#Eval("Property")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:Label ID="lblProperty" runat="server" Visible="false" Text='<%#Eval("Property") %>'></asp:Label>
<asp:DropDownList ID="ddlPropertyEdit" runat="server"></asp:DropDownList>

I have entries for an enumeration stored inside a database table with only the following fields: ID and Name. I want to show the values stored inside this table inside a DropDownList on a form. The user then chooses a value and submits the form.
I found a way to easily create a DropDownList from an enumeration (although it would probably be best to just populate the DropDownList with the Name fields of all the records in the table). However, I haven't found a way to later bind the DropDownList in the form submission to an integer value to put into the database (FK - PK) with the other form values.
is it possible to fetch DropDownList content via AJAX and have it be put into the DropDownList and into the SelectList in the ViewModel (with both the ID and Name parameters)? I want to selectively fetch content based on an input the user makes and I want the ViewModel to then be filled with that fetched data.

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.

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"

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 the following Dropdown List
[code]....
My problem is that some of the users that used to be in the list have left the company so we want to mark them inactive. When they are inactive they should not show up in the DDL to be selected to be assigned to. But there are existing records that they are already assigned to. If they are no longer able to be assigned their is a column called IsActive in the db that is set to 0. The Datasource filters for only == 1 when filling the datasource.
When it tries to render the control where a selected value is not in the list the Browser throws an error. I can not seem to find an event where I can intercept and set a value that is legal.
The solution I would like would be to add the listItem to the Control in the code behind then call the bind("AssignedTo") in the code behind instead of in the aspx page. This way linq would still handing the update of the DB record for the update event.

I have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.
Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.
Here's what I have so far:
[Code]....
And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.

I'm having trouble binding my textbox to my dropdownlist. I got it to work but I don't think it is the correct way of doing it. I have my DDL bound to a datasource and populating everything correctly. However, I couldn't find a better way of binding my textbox to it besides using the FormView control and its counterpart, Templates (edit,insert,etc) It looks messy and i was hoping there was a better way of doing it. I've researched it online for awhile now but I couldn't understand how to implement for my situation.
My DDL has company names in it and the datasource has all the information from the table including what I'm trying to have my textbox pull (Address).
