Assign values to SqlDataSource Parameter from drop down list in InsertItemTemplate


Good Afternoon;

I have a Detailsview grid with an SqlDatasource, this DVG is only going to be used to insert records. The primary purpose of the DS is to populate a DDL control in the insertItem Template that I created my code is this:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConflictDetection="CompareAllValues"
            ConnectionString="<%$ ConnectionStrings:testdbConnectionString %>"
            InsertCommand="INSERT INTO tblSelections(sTesterID, sTestDate) VALUES (@TesterID, @TestDate)"
        SelectCommand="SELECT tName, tExternalID FROM tblTesters">
                <asp:Parameter Name="TesterID" />
                <asp:Parameter Name="TestDate" />

The DDL control populates correctly, but when I try to modify the  INSERTCommand property in my DS, I try to assign the value to my parameters "TesterID" and "TesterDate" but the only options for controls to pick from, is the DGV but not the DDL in it. I assume it has to do with the InsertItem template but even if I reset it I still cannot pick

How to use a drop down list to edit in the standard Edit.aspx with DD?


Hey All,

I'm brand new to Dynamic Data and to ASP.NET.  I've been able to fumble around and get the calendar extender up and running and a few other customization options implemented, but I can't seem to get this drop down list to work - even after reading tons of online info.  The good news is that my web page/application is VERY simple, so hopefully you guys can help me out.  I'm working in VB btw.

I have a list of road projects submitted to me by local governments.  One of the fields is SponsoringAgency, which has a limited number of possible entries (the names of member governments).  Thus, when they submit a new project, or edit an existing one, I want to limit the input into the field "SponsoringAgency." I'm trying to use a dropdownlist because I'm familiar with it from Access, but it may not be the best approach.  Imagine you just setup a brand new, standard DD website, how would you get this to work?

Methods tried and failed (probably because I don't understand them fully):

UIHint - The closest I can get with this is an error saying that since SponsoringAgency isn't a Foreign Key, I'm out of luck.

Creating a SponsoringAgency Table - In my data layer, I created a second table with a list of government names.  I then tried se

FormView Text Field Being Set by A Drop Down List


Hello, I have a FormView which is used to insert a record into a database.  Outside of this formview i have a drop down list, I want to grab the value from that drop down list and set one of the text fields within the formview to it's currently selected value.  I've tried the following code, but the dynamic categorytextbox line is what seems to not be working.

                    <asp:DropDownList ID="ddlCategory" runat="server" AutoPostBack="True" 
DataSourceID="SqlDataSourceCategory" DataTextField="CategoryName"
DataValueField="CategoryID" Width="200px">

                            <asp:TextBox ID="CategoryIDTextBox" runat="server" 
Text='<%# Bind("CategoryID") %>' Visible="False" />

        protected void FormView1_DataBound(object sender, EventArgs e)
dynamic varCategory = ddlCategory.SelectedValue;
dynamic categoryTextBox = FormView1.FindControl("CategoryIDText

Cascade Drop Down List Problem


I have 4 "cascade drop down linked" each other. The first one is "AccesoryFor", the second "TypeOfAccesory", the third "MarkOfAccesory" and the fourth "ModelOfAccesory".

The problem is that sometimes is possible in the web page I'm programming that a "Session Variable" could have a value that must be selected in one of that ddls. But not only that, the "ddl" or the entire "row" where the ddl is located ,must disappear. The problem is that, when the page does the rendering process, the others "cascade drop down" don't find its "control parents", so they stay disable and without data.

So, what I do in the Load Method:

 protected void Page_Load(object sender, EventArgs e)
        if (!IsPostBack)
            Session["AccesoryFor"] = "cellphone";

 public void loadValuesToUI()
    if (Session["consultarRecursos_AccesorioDe"] != null)
            rowAccesoryFor.Visible = false;

As the row where the first DLL is located dissapears, and error occurs saying that "Control-Parents" are not found. There's no way to "Disable" or make dissapear the ddl in the web-service because

How to get selected text of a drop down list in MVC?

I aggressively googled around, but could not find the information I am looking for.  I know how to populate a dropdownlist using my view model and Html.DropDownListFor helper method.Suppose the drop down list contains U.S. stateId and stateName key value pairs.  Suppose my ViewModel looks likepublic class MyViewModel{      public IList<State> States {get; set;}      public int SelectedStateId {get; set; }}public class State{     public int StateId {get; set; }     public string StateName {get; set; }}Now, in my controller's action method:[HttpPost]public ViewResult Index(MyViewModel  myViewModel){     // This following line seems to work fine, myViewModel automatically      // picks up the selected item of the drop down list.  How does this work?      // Is this the so-called model binding?      int selectedStateId = myViewModel.SelectedStateId;      // But, then, how do I get the selected state name?     string stateName = ??????????????     ... ... }Do I have to change my implementation of my view model?  In any case, how to get the selected item text of the drop down list?  Any hint?  Thanks a lot.

Create drop-down filter for External List

I hope this is an easy question. I will have an external list of a bunch of people.  There are several ways I want to display this data: All of them, Only the ones that have a value of 1-4 in the status field, Only the ones that have any other value in the status field, and people that have a value of 1-4 in the status field, but are at a certain location. I want to be able to put a drop-down filter above the list where people can select that. Could someone please point me in the right direction? Time is of the essence.  

Dynamically Drop and Create tables, overcoming 4000 charachter limit

We have a Navision SQL-server database for 7 companies. Each table starts with the name of the company. Except for the CompanyName-part, the tables names are equal. I made a Foreach loop that dynamically transfers tables/data from the the Navision-database to a staging-database. I also want to Drop and re-Create the tables dynamically. However, if I try to do that via an expression in a SQL Task, SSIS complains about the 4000 character limit. What is a better way to do this? I want to execute SQL-commands and have SSIS replace part of the tablename with the contents of a variable (being the name of one the 7 companies). I have no access to the Management Studio or the DB so I need it to be done within the package. What is the best way to do that?

Autopostback on the last list in a Cascading drop down list series

Hi,First off I'm very new to Ajax for .NET.  I have a Cascading drop down list that is working fine to load the correct lists however I would like to have the last one initiate a query and display a datagrid on the same page containing the results of the query.  Without Ajax involved this seems rather easy by using autopostback on the drop downs.  If I could do it through Ajax that would be great but I can settle with having the page to reload to display the data.  Right now I'm not sure how to do either.  I enabled autopostback on the last drop down and wrote a method for it but I get an error at runtime saying:Invalid postback or callback argument So I'm really not sure what to do to get this to work right.Any help would be appreciated.Thanks,-Jordan
