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.

I have followed the documention for adding a radio button select column to a gridview and all works fine. Except, I am using a wizard where the user must select a value from this table before pressing next. Using the validator is not possible since the radio button is created using a literal. Is Javascript the only way? How can I prevent a user from clicking next using Javascript?

I have a dropdownlist (drpClients) bound to an object datasource (odsProgramClients). In the dropdown's databound event, I load a dynamic table based on the selected item in the dropdownlist. This all works well. However, if I force a problem in odsProgramClients select method, it continues to the databound event of the dropdown and attempts to load the table, even though dropdownlists underlying select method failed. I wish to stop the databound event from firing if there is a problem in the select method. I have code that traps the error in odsProgramClients select method.

How do I stop the dropdownlist from databinding, if there is an error in it's underlying datasource?
Is there any method by which we can retrieve random data from a dataset or rather directly from a table.
For example, I have around 30 questions in my table, I just wanted to display 20 among them and that too in a random order without the same item repeating. Can we achieve this using SP or through some Dataset manipulation?

I am trying to reconstruct a date/time period from five data elements Year, StartMonth, StartDate, EndMonth, EndDate If the event starts on June 5 and ends on June 6, 2010 - The label would read June 5 thru 6, 2010. If the event starts on June 30 and ends on July 2, 2010 - the Label would read June 30 thru July 2, 2010. and if the event starts on June 5 and ends on June 5, 2010 - The label would read June 5, 2010.

I'm trying to use a variable returned from the database as an integer. My thought is to use a Link button and when my user clicks it, it should open a new window. However, its giving me an error stating the value is in the wrong format. Here is my link button code.

<asp:LinkButton ID="LinkButton1" runat="server" Text='<%# Bind("Name") %>' PostBackUrl='profiles/profile.aspx?id=<%# Bind("ID") %>'></asp:LinkButton>

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 happen to have used datasets and hence data tables in most of data access approaches.
This time arround i want to exctract the integer value and use it in the if statement for testing.
I however face a problem in the fact that though i can select the particular cell in a table i still get a table adapter which is not what i need and is not covertible to int value.
See the code below:

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}")) %>

I have the following code reading in my xml file and sorting it by ID:
Dim ds As New DataSet
ds.ReadXml(Server.MapPath("/posts.xml"))
Dim dv As New DataView(ds.Tables(0))
dv.Sort = "id desc"
The only problem is that it isn't sorting it numerically (it's sorting it alphabetically 1, 10, 11, 2, 24, 3, 4...). It appears as though I have to convert that column into integers, but I haven't been able to figure out an efficient way to do that.
im ds As New DataSet
ds.ReadXml(Server.MapPath("/App_Data/posts.xml"))
'ds.Tables(0).Columns(0).DataType = TypeOf(Decimal)
Dim dv As New DataView(ds.Tables(0))
'dv.Sort = "date"
I'm trying to retrieve selected DataKeyValue and I'm getting this error.
