This is my programs complete code, the only problem is i want to fix the amount of decimal places that show up in my gridview. The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.

DataSource Controls :: How To Change A Table Column Data Type

Jan 21, 2010

I attempted to change a table columns data type and in the process caused a lot of issues. I had a date column in one of my tables and stupidly changed it from varchar to date. When I tried to run queries on it I keep getting the 'cant find column 3 error'. Now that tables structure is :

[Code]...

So column 4 is actually the date column. All other queries work for this table. I then tried to change it back and then copied all data to a new table and now I am using the new table and converting the dates as needed but I am still getting the error.

SELECT * FROM postlinks WHERE postlinks.date >= CONVERT(datetime,CONVERT(varchar(10),GetDate(),112))

Forms Data Controls :: Creating A Form With An Unknown Number Of Rows?

Sep 13, 2010

I'm pretty new at ASP .NET but not to ASP. I've got a form I need to create where I don't know how many entries will be added. It has the following format:

"Age" "Duration" "Period of Duration" "etc..."

Last30Days

1-5 Months ago

6-11 Months ago

Age

Age

Age

etc.

So the Age column always has the first 3 options and then an unknown number of Age values that can be inserted. I've created a table that has the first four fields (Last30days, 1-5months, 6-11months, age) and I was thinking I could just order by those 4 columns for display. The problem I have is I'm not sure on how to proceed. Does anyone have any good ideas on how to handle this situation? Ideally data entry people could use the same form for both entering and displaying the data.

Forms Data Controls :: Conversion From Type 'TextBox' To Type 'String' Is Not Valid?

Sep 6, 2010

I have a FormView that allows a user to register for a company event. I want to do a couple of things with this form.

1. I need to write this data to a MS SQL database

2. I need to send an email confirmation of their registration to their email.

I know how to do both of these things, but i am having trouble doing both at the same time.

It would be nice if I could do it in one click, but I coded it into two pages to try to help simplify it.

The first page allows the user to input their information into a formview and when they click the submit button, it places those answers into session variables:

[Code]....

[Code]....

The Second page confirms the users information by taking those session variables and placing them into labels:

[Code]....

[Code]....

However, after I place information into the formview on the first page, it throws up this error:

"Conversion from type 'TextBox' to type 'String' is not valid".

Syntax Error Converting The Nvarchar Value To A Column Of Data Type Int?

May 5, 2010

I have 1,2,3,4,5,6,7,8,9 stored as nvarchar inside Level in my db.

I then have a dropdownlist with values 1,2,3,4,5,6,7,8,9. When a user makes a selection (i.e 1) (Level.SelectedValue.ToString). This builds an sql query via a param like this:

"Select things From MBA_EOI Where level = 1"

When I run the select I get the following error:

Syntax error converting the nvarchar value '1,2,3,4,5,6,7,8,9' to a column of data type int.

I was under the impression that I was dealing with an Nvarchar field and the selected value as string, where does the int conversion come in?

p.s I have also tried Level.SelectedItem.ToString
