View 2 RepliesHow to assign a array string session to dataset or datatable? I have a array session data in that i stored n number of values. i want to assign these values to dataset. so that i can bind these values to gridview. so anyone pls let me know how to do this? Iam getting error to convert sesion{"noncontractitem"] to datatable.
string[] sessiondata = { txtProductNo.Text, txtItemDescription.Text, ddlUnitOfMeasure.Text, ddlDistributor.Text, rbtlItemType.Text, txtQnty.Text, txtPacking.Text, txtUnitCost.Text };

I want to group by the date, these values are now in a dataset. What comes up to my mind is an array list with the following: The master array would have each date listed on the dataset above, within each row of this array I would have the list of numbers for that specific date. How do I do that in VB.NET?
I would like to split the string to the string array.
but when the string hasn't has the splite sperator, i can't put the string into string array directly.
how to do?
if (Str.Contains(','))

}
else
{
str_array=Str; <-- error occurs at this line.
}

I have an unbound gridview.. which uses databind instead of sqldatasource..
the thing is how do I modify the title of the column name?
For example.. instead of
MemberID MemberName MemberAddress.... i want it to be like
ID Name Address..
Sample code:
cmdSelectService = new SqlCommand("SELECT JobPost.JobPostID, JobPost.JobPostInformation, JobSpecialization.JobSpecializationName,[code]....
I have a gridview with 3 columns. In second column I want to display some text in 2 rows and then a gridview.
Here is my code:
[Code]....
The problem is my third row is displayed as a row under first column. How do I make it a separate column in my girdview. Not sure what is going wrong.
Just to be forward, my .net and c# expierence is very limited, that one could say I'm a complete noob :) However I do have some grasp on OOP as I usually work in PHP (FWIW). My problem seems to be with this line:
Session["total"] = dt.Compute("SUM(price)", "").ToString();
which will output a total of say "9.2" where as the price is "9.20" from a few record lines as such:
dt.Rows.Add(strRecord, 9.20, dropDownListDistrict_stepTitle.Text);
thus 9.20 + 9.20 = "18.40", but the page displays "18.4".
The label that displays the total sum is:
<asp:Label ID="labelTotal3" runat="server" Text="0" />
From what I've gathered, I'm suffering from some kind of type casting problem? Hopefully I haven't missed anything, its a bit difficult to show all the code but hopefully someone can point me in the right direction? Question is; how can I get an extra decimal place to show up on my sum (or why is it dropping the last decimal place?).

View 6 RepliesI have 2 datasets as shown below,
dsDBFFulfillment = conn.GetDBFDataSet(ReminderQry);
dsDBHcniID = conn.GetSQLDataSet("spGetRemindpostcards", null, ConnectionType.SRRDConnection);
I have a result in dsDBFFulfillment,Consider the field HcnID,Name,Address In the second dataset dsDBHcniID i have only HcnID.
Now in the third dataset i want a result such that,
1.The records in the dataset dsDBHcniIDshould be removed from dataset dsDBFFulfillment by checking HcnID.
Something like this, dsDBFResult = dsDBFFulfillment.Tables[0].Rows.Remove(("HcnID='" + dsDBFFulfillment["HcnID"] ));
I am trying to display rows which are returned from several stored procedues and then stored in dataset tables.
When I loop through the tables/rows/columns collections no data is displayed.
Here is my code :

I am getting no error message and there should be data returned becaue I can execute the SPROCS through the VS serve explorer without a problem.
i have a strange error creaping into my web app but am unsure as to how to fix it. When i run this code on my debug workstation it works fine but when i transfer it to my server things seam to go wrong.
dev station (windows 7) + VS2010
regional and language settings all set to uk
server (windows 2008r2)
regional and language settings all set to uk
What seams to be happening is that when converting a string to a double it works correctly on the dev environment but moves the decimal place to the end on the server.
example code(vb)
dim lat as string = "52.983829"
dim long as string = "-0.036500"
dim latint as double = lat
dim longint as double = long
now on the dev server the value of latint is 52.983829 as you might expect but on when published to the server it becomes 52983829.0 the same with longint on the dev staion it is -0.036500 but on the server it becomes -36500.0 i get equally confusing problems if i try to change it to an integer instead.
I got "DataRow[] rows " and I want to insert into "DataTable tb " not using loop.
Is there any single statement to insert/add all rows at a time.
which part when wrong if my code is wrong ? I'm using VS2010 have a dataset. Here is my code. [Code]....
