On my web pages I display the data as mm/dd/yyyy and that is how the user will enter the dates as well. But when I pass the textbox control that has the date in it as a parameter to the SQLDataSource control, I need it to be sent in the YYYY-MM-DD format for the AS400. Is there a way it can be changed in between?
View 7 RepliesI have a sqldatasource control that I want to get the field values from as it is selecting. Is there any way to do this in the dsControl_Selecting event for each record without binding it to any control or formview? I would like to call dsControl.DataBind and retrieve the field values.
View 4 RepliesI have a text field that users enter information into a database (SQL Server). They are entering as little as a few sentances to multiple paragraphs. I can successfully display the data on my webpage, but the text field is not formatted very nicely. The output is all smashed together like one big paragraph. Ironically, when I also display the text as a tool tip it outputs as multiple paragraphs like it was entered. How can I format the output in the datalist to create a more readable text field? My datalist field is as follows:
<asp:Label id="WebDescriptionLabel" runat="server" Text='<%# Eval("WebDescription") %>' ForeColor="Brown" />
I found a very piculiar care in ASP.Net MVC webpage submission to server. The model object is bound to the action event. It was working fine. I added another interger field to my model object and added a control to the webpage(.aspx). When I submit the page without entering data in the new field, I found that my ModelState.IsValid in the Action Event, is false and there is error registered as the field value is required. I am surprised why it will be a mandatory field? when I have not set is as Mandatory ? Is there some thing wrong I am doing? I putting the samples below.
New Filed in ASPX:
[Code]....
Controller Object :
[
{
AcceptVerbs(HttpVerbs.Post)]public
ActionResult AddDriver(Driver driver)
}
On submit of the page when control comes to the AddDriver Action event , I found the ModelState.IsValid is false.
why it is happening as I have not put any require attribute in the Model object's field.

When the data is retrieved through a stored procedure using the SQLDatasource control that is binded to a gridview control, I want to change some data that is in some of the columns. Can i do this in one of the events either in the gridview or data control? I know you can do some formatting on the aspx page side such as dates, etc. but was wondering if I can do it on the vb code side?

I have a GridView that records can be added to.There are only 2 fields in the table that the records come from which are date field and an integer field.The date field is fine "as is".The problem is that you can't format the integer field.I have tried every way that I can think off.The last 2 ways that I have tried have used String.Format because I am using EVal and with Eval you can supply anoptional second parameter to specify a format for the returned string.I have tried in both html and code behind , html gives an error message but the code behind (code behindthe RowDataBound method) doesn't give an error message:In the html looks like:
<ItemTemplate>
<%# Eval(("inFrmDate").ToString(), String.Format("{G}")) %>
</ItemTemplate>

View 1 RepliesI'm looking for the easiest way to bind data from a SqlDataSource to textboxes dropped in Visual Studio 2008.
For example, I have 4 textboxes currently that have Address, City, State, Zip. I also have a SqlDataSource on the page fetching the ID of the record and selecting those 4 fields based on ID.
How am I able to quickly bind each box to those particular fields selected? I would think this would be really straight forward - but seems it's not. Seems like the answer is funneled towards having to create a GridView or some type of control.
I get the Erorr: Input String was NOT a correct format.
The first three controlparameters are STRINGS and they work fine.
However the last two populate the controlparameter from text boxes that can only accept numbers and decimal point.
First the text boxes for {3} and {4} string parameters in the SQL filterexpression:
[Code]....
And then the SQLDatasource control parameters[Code]....
The last two control parameters are the ones is question as they feed {3} and {4} parameters in the filter expression, NOTICE how I set the type="double".The data input is expected to be like 152.25 or 3.6 or 4 etc,So why am I getting this error: [Code]....
I have a datasource that is connected to a stored procedure and I need to do a postback on the web page but do not want the sqldatasource to do a databind. What I am doing is when I change a dropdown box to fill in some textboxes with specific dates, I do this on a postback so the textboxes are filled in with the dates. But the SQLDatasource control data binds again and shows new results in my gridview.
Is there any way to prevent this so I can just postback to fill in the textboxes?
I have a list of numbers I need to submit one at a time to a stored procedure to add to a table. I don't know any other way around this. The database for this is an AS400 so it's not like using mssql server. I have a connection string and use the SQLDatasource controls to select data because I can select a stored procedure with it to call. Now I need to do an update and if it was just one time of submitting information I would do it the same way. But I need to submit each number till I do them all. How can I do this? Do I still use a sqldatasource control and set the value to be pulled from like a session var and just loop through setting the session and then sqlds.databind over and over? I added a DBML but can't do that with the as400 stored procedures as far as adding them like I do mssql.
View 5 RepliesI typically don't use the sqldatasource control but trying it out and can't seem to get the delete function working. It doesn't seem to be passing a parameter to my stored procedure.

When I drag and drop an SQLDataSource control to my new web page it disappears after I set it up.
It exists in Source but I can't see it in Design. I'm doing the same thing I would do in VS 2005 and I can see the control in design view.
Why can't I see the control? I'm new to VS 2008 and .Net 3.5.
I use the sqldatasource control a lot with stored procedures. But this time I'm using some code I found online where I am defining the new sqldatasource in the code and using it. You can see this below. I am getting a NullReferenceException on the first SelectParameters line and not sure why. Do I need to add the parameters different?
Code:
Dim SqlDataSource As New System.Web.UI.WebControls.SqlDataSource()
SqlDataSource.ConnectionString = ConnectionString
SqlDataSource.SelectCommand = "MySprocName"
SqlDataSource.SelectCommandType = SqlDataSourceCommandType.StoredProcedure
SqlDataSource.SelectParameters("Distance").DefaultValue = 25
SqlDataSource.SelectParameters("ZipCode").DefaultValue = "31410"
Dim arg As New DataSourceSelectArguments()
Dim dv As System.Data.DataView = DirectCast(SqlDataSource.[Select](arg), System.Data.DataView)

I am wondering how to handle and setup a means to submit multiple data entries via ASP.NET MVC.
Suppose I have a product database table such as: ProductId, ProductTitle, Price.
From the view, I was thinking to code the HTML form as:
<form ... >
<table>
<tr>
<th>ProductId</th>
<th>ProductTitle</th>.......
Suppose the form is to be submitted to Controller: Product, Action: Add. What sort of coding techniques can I use to handle this dynamic form, such that I follow good or best practice, and if possible also be elegant.
The solution I see so far is to test the Request.Form (or Formcollection) indexer/dictionary for existence for the dynamic input fields. E.g.
public ActionResult Add(Formcollection form)
{
int productEntry = 1;
string productPrefix = "Product";
while(true)
{........

I'm trying to make my string a nice formatted time but the column in the database isn't set up as a date/time field is there anyway I can do this? Here's my query
Dim query as String = "Select * from openquery (devbook, 'SELECT wb.arrival_time FROM web_bookings wb ')"
And here's where i'm converting it
Session("formattime") = DateTime.Parse(drv.Row("arrival_time")).ToString("hh:mm")
The arrival_time field only has 4 numbers in like this 1000 so I need a way of converting it to a nice format like this 10:00AM
