How to populate the values of drop down list box from an xml file keeping the above consideration.
I am doing this in a asp.net user control and C# code behind
In future i need not change the code every time. Its only the xml file i change and the corresponding city related office locations get listed in the drop down list box.

I am "trying" to switch my form from SqlDataSources to ADO.NET data sources. So I have a DAL setup, and ObjectDataSources in my form referencing these DALs. These data sources are bound to the form's objects. So far so good. In the InsertItem Template of one of the form's FormViews I have a list box that I am trying to populate with a value pair (ID, TechName) from a database table and I get the following error:
"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control." Apparently, one of the two workarounds involves programmatically loading the listbox. The code below shows one of my attempts, resulting in the above mentioned error:
Code:
Protected Sub TestFillDefaultValueInFormView()
Dim vInspectorList As DropDownList
If (FormViewHydInspection.CurrentMode = FormViewMode.Insert) And Not IsPostBack Then
vInspectorList = DirectCast(FormViewHydInspection.FindControl("DDlstInspBy"), DropDownList)
vInspectorList.Items.Clear()
Dim vInspectorDA As New DataSetHydrantsTableAdapters.TechnicianTableAdapter()
Dim vInspectors As DataSetHydrants.TechnicianDataTable = vInspectorDA.GetTechnician()
Dim vInspRow As DataSetHydrants.TechnicianRow
Dim vInspectorHT As New Hashtable
vInspectorHT.Add("0", "Select Technician")
For Each vInspRow In vInspectors
If vInspRow.TechID <> 0 Then
vInspectorHT.Add(vInspRow.TechID.ToString, vInspRow.TechName)
End If
Next
vInspectorList.DataSource = vInspectorHT
vInspectorList.DataTextField = "value"
vInspectorList.DataValueField = "key"
vInspectorList.DataBind()
End If
End Sub
I tried populating the listbox directly using the Listbox.Items.add() method (which is the way I have it now so I could continue solving other problems, and it works!) but I could not find a way to add a value pair. I did try:
vInspectorList.DataTextField = "Select Technician"
vInspectorList.DataValueField = "0"
but that left a listbox without any data.

i've created a webform with one gridview having connected with the database using datasource. i.e password database with three colomn .
now want to insert the custom dropdown button using server control for each column.
when i select the dropdown list the list should display the value as required.
e.g if i click the uname dropdownlist then it should show the list of names.
if i click on pwd dropdownlist then it should show the list of numbers.
if i select any one of the value in the dropdown list then it should insert into the
database.
can i get code on this type of question...?

How would I add a (dropdown) list of available values for a custom server control property?
(Just like 'Visible' property of most controls has valid values of 'True/False' and nothing else can be entered or selected)

I have some (probably very basic) questions about developing custom controls. I am wanting to derive a set of button controls, and the first one I have started on is a "DeleteButton", that has a additional property (DeleteConfirmationText) that is built into the OnClientClick attribute. To get that added, I overrode the Render method as follows:
[Code]....
This all works well. Now, I will add some logic to make sure that there is some text in the DeleteConfirmationText property, but that isn't the intent of my question.
What I am also wanting to do is to override some of the default property values, so I added that to the default constructor:
[Code]....
Now, in the designer in VS2008, and I look at the properties for the control, there isn't a default value shown in the "Properties" section, and the Causesvalidation still shows the underlying classes default value of "True". As well, in design mode, where the GridView control that containse my DeleteButton control would be displayed, there is an error box "There was an error rendering the control. 'Are you certain you want to delete this attorney?' cound not be set on property 'DeleteConfirmationText'. Here's the markup where I am defining the deletebutton control:
[Code]....
What am I doing wrong?

I'm creating a user control that enables users to search AD and add the selected names to a list (which is used to send mail lateron).
The problem is that the search results end up in the Listbox but all as the string "System.DirectoryServices.ResultPropertyValueCollection" in stead of the actual values.
I have no idea why.
This is my code:

I am creating a custom server control, and I am wanting to include a JavaScript file in the dll file when the control is built. I have tried suggestions from the following websites:[URL] But after following the directions, If I use firebug to see what errors show up, the JavaScript functions that are being called all say "goNext is not defined" which leads me to believe the JavaScript file is not being added correctly.
Some information on what my control looks like
I have the JavaScript File in a folder called Script. The namespace of the project is CustomControl, and the Name of the project is MaskedDateTextbox.
In my AssemblyInfo I have the following:
<Assembly: AssemblyVersion("1.0.*")>

I am trying to persist data in a dynamically populated ListBox in a user control. Here are the details
I have a user control which contains a a listBox and button. On Page_Load of user control I am populating the ListBox control with some values. On Click of button, I am trying to fetch the values which I have selected in ListBox. Though this seems very simple and straight forward I am unable to fetch values.
My Page_Load Function
void Page_Load(object sender, EventArgs e)
{
If(!IspostBack)
{
listBox.items.Add("Item1");
listBox.items.Add("item2");
listBox.items.Add("item3");
}
}
My Click Function
Protected Void Button1_Click(object sender, EventArgs e)
{
string strValue = listBox.SelectedValue
}
I have placed brake point at Page_Load and on click function, I am seeing that the moment the breakpoint hits Page_Load function (before If (!Ispostback)) , listBox.SelectedIndex is becoming -1.
One more thing here is, I am placing this user control in an SharePoint application page to be specific checkin.aspx page . ( I know this should not be done, but that is the requirement for me)

I'm having a dumb problem that is killing me. I have created the simpelest custom server control in VS 2008 c# called MyMsgBox. On the ASP page I put it in and register it. But, in the .cs file, when I try to call one of its functions I get the compile error that it is not found. The funny thing is that intellesense has it in the list and all of the functions with their given arguements. At the top of the .cs file I am using the namespace. The code for the custom server control is in the App_Code folder.
Also when I remove all refrences to its functions, the code compiles and when debugging the constructor for the class MyMsgBox gets hit.
<%@ Register TagPrefix="cc1" Namespace="CustomServerControls" %>
...
<cc1:MyMsgBox ID="msgBox1" runat="server" />
Task.aspx.cs
...
Using CustomServerControls;
...
this.msgBox1.confirm("Would You Like to add a new Task for this PO/Contract? ", "hid_f"); Error Message: 'Tasks' does not contain a definition for 'msgBox1' and no extension method 'msgBox1' accepting a first argument of type 'Tasks' could be found (are you missing a using directive or an assembly reference?)

I am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1
I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.
can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?
FYI I am using Visual Studio 2010 and SQL/Server

I have a complicate problem. I'm not sure if I can explain it clearly. I have SQL table with columns: id, PartNo, ManuPartNo, GovtPartNum.
My boss want to do like this with 3 dropdown or 1 Dropdown with 2 listbox: If he select any PartNo, it will pull associated value For ManuPartNo & GovtPartNum
Also, if he select any ManuPartNo, it will populate back to other dropdown
Also, if he select any GovtPartNum, it will populate back to other dropdown
I'm so stuck & I don't know where to start on this.

I'm using a List Box to get multiple values that will be used in a query.I can loop over the List Box and create the string.i.e. 'blue','red','purple'The string is used in the query: SELECT * FROM TABLE1 WHERE COLOR IN('blue','red','purple'). Is there a way to parametrize multiple values? @COLOR='blue','red','purple'What will be the best practice to prevent SQL injections in this scenario?

I've created loads of user controls, but this is my first time dealing with extending a server control. The problem I'm getting is that the base control's data is not being persisted across postbacks in a Master/Content page.I'm actually trying to get this working using a Telerik control (for my sins), but the same issue happens with a standard Web TextBox control. Code:
[Code]....
Now, I've copied the way I handle the control state as I do it with user controls (ControlState), and it isn't working. Can someone point me in the right direction please? All the examples I find refer to creating user controls, not extending existing controls. Specifically why nothing is being persisted on post back.
