I have req where i have to check the value coming from db is null or not and assign value according to that.Problem here is the field datatype is 'Datetime' so all the time when I tried to use the below line of code its giving me error.How can I pass a null value to datetimefield if value coming from db is null.
(reader["FieldName"] == DBNull.Value) ? string.Empty : (DateTime?)(reader["FieldName"]);
I came to know that string.empty is making problem,what value we can pass instead of string.empty for a datetime column in C#.
What I want is ,Field value will get null value assigned not zero.
i have a datatable with several columns and rows. now i want to copy the last column fully (all rows) and create the new column with that values.
it means last column values sholud be moved to new column (now this is the last column).
Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.

how do i multiply the columns like this. for now static explanation would be ok but eventually i would like to make it dynamic so there would be a text box for users to enter the amout they like e.g 160g then the table would know to multiply the columns by 1.6.

I am very new to ASP .NET and am getting above error when trying to insert a new record into a SQL database. I have turned on Option Explicit On so the default date of 01/01/1900 does not get assigned to this field automatically. Since most of the people in the database will not have a date of death, I need to have "blank" deathDate. When I run the stored procedure within SQL and choose pass null value, the Insert Procedure works fine. When I attach to Web Form, however, I get String was not recognized as a valid DateTime error. How can I set it so Null values are accepted into this date field.

Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?

View 4 RepliesI have a column with nvarchar datatype storing the date. I am using a Gridview to display and edit data of that table. Now when I update the table the nvarchar column containing date in the format mm/dd/yyyy gets converted to Jun 9 2010 12:00AM format. I don't want this to be happening. I don't understand why this is happening as I don't have datetime column.
