I have a dataset that has just one column and one row. It gives me an integer. I have to save it in an other integer.
Dataset pds;
if (pds.Tables[0].Rows.Count > 0)
{
int Islocationcount = pds.Tables[0].Columns[0].ColumnName[1];
}
I am having dataset and I want to validate particular column for Integer(Numeric) value.
e.g.
ErrorRows = dt.Select("LEN(Year) <> 4 ")
Above I have to validate Year column for Numeric value otherwise it should give me erroneous records which have data other than numeric.

In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.
FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.
Is there a way to convert the data in my gridview to a virtual DataSet?
I've written the following method to get the data:

Till now I used to design RDLC file before and assigned typed dataset table columns.Report processing mode is local. But now my stored procedure returns different columns based on condition i.e columns are not fixed every time. Now I need to add that columns to typed dataset and dataset is assigned to RDLC file. So dataset and RDLC files are create dynamically based on stored procedure result set columns.
View 1 RepliesWhat I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.

View 1 RepliesI am using Entity Framework with partial classes added on so I can use DataAnnotation attributes. Does anyone know how to add a data annotatin which will verify that a field is a whole number (or a DataType of int or long)? I'm surprised there is no [DataType(DataType.Integer)] attribute. I tried to create a custom attribute, but it doesn't work because the value it receives is always null:

The questionID is Primary 1,1 so what I need to know is do I have to write another SPROC or can I get the highest number row or last row throught the value. For instance,

I have a query which need to search on account table where search criteria looks at either partial name(string column) or partial accountid (integer column).
Linq doesn't allow tostring on integer column to find partial search. The example would be search account number which begins with 124. There might be account numbers like: 1247, 1249 etc which need to be returned. On the name side, searching for string that begins with joh would return john, johk, johp etc.
FYI: The query should return Account table records not annonymous types.

i'm using an entitydatasource to save an entity which has an nullable integer property with the default value 0,this property is bound to a textbox in a formview.I assume that when I leave the textbox blank the datasource should understand that I want the property to have null and set it to 0 by default, but it acts different way, it doesn't save the enity at all and gives the entity in Updated and Inserted events as null:

I have an integer field in my sql database and I have an xsd set up with all the CRUD operations. I need to put the value in a variable into the this integer field. Sometimes the value is 'nothing'. I have option strict on so there's no conversions going on by itself. If I hard code 'nothing' into the insert query, it works fine. Here's what happens otherwise:
1) If I put a variable into the query, when I assign 'nothing' to the variable, it becomes 0 so it puts a 0 into my database.
2) If I use an iif( ) statement, it also converts 'nothing' to 0
I don't seem to have any way to get a nothing in there if I don't specifically write 'nothing'.
I am using the following code,
vb Code:
Partial Class _Default Inherits System.Web.UI.Page
Public count As Integer = 0
Protected Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick count += 1
Label1.Text = "You clicked the button " & count.ToString & " times!" End Sub End Class
however, all the page ever displays is "You clicked the button 1 times"
My page (which basically contains a pair of Repeaters) renders and is displayed to the user.I'd like to have a "Download" button on the page which, when clicked, will propmt the user to save the page locally as an html file without losing any of the CSS formatting.
My CSS files are linked to via a Master Page.Currently, I have the button linked to some javascript that open will the Save As dialog, but all of the CSS formatting is lost, and it saves the page .I'm assuming that the button will need to open a new page which will re-create the data for the Repeaters and then save using StreamWriter, but I'm not exactly sure if that's right or how best to do it.
one button i use to save form entity.and other is to navigate to next pagwhen i click on save button i use jquery to save form entity in database. and form remains as it is
<script type="text/javascript">
In a project when user click a button, some data is gotten and written to an excel instance by interop library.
Now, I want that: When excel instance get all data, a save as dialog box muste be open and save this excel instance to user specified path.
Is there a way to do it?
