I'm new to DataGridViews. I have successfully created an unbound DataGridView that contains columns of string, numeric and date values, but I can't seem to figure out how to define a column as a numeric or date value--only strings. I have enabled sort on the columns so the user can click on any column to sort by that column. When I click on the numeric column, it sorts like:
12345.56
13.35
1442.22
...
The dates also sort as strings rather than dates.What is the code to change the data type of an unbound DataGridView column? Is it possible? If not, how can I do this with my unbound data?

View 8 RepliesI am using C# windows based GUI and MS-Access as my database. Unfortunately, I cannot insert a record with a numeric value, this means that one of my field is a number data type. Below is my code;
Code:
strItemCode = lvProducts.Items[i].SubItems[0].Text.Trim();
iQty = int.Parse(lvProducts.Items[i].SubItems[2].Text);
cmAdjustedItems.CommandText = "INSERT INTO tblAdjustedItems VALUES(@itemcode, @adjustmentid, @qty)";
cmAdjustedItems.Parameters.AddWithValue("@itemcode", strItemCode);
cmAdjustedItems.Parameters.AddWithValue("@adjustmentid", strAdjustmentID);
cmAdjustedItems.Parameters.AddWithValue("@qty", iQty);
cmAdjustedItems.ExecuteNonQuery();
All the variables in my code were properly declared.

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".
I have a gridview which I'm trying to get the display of phonenumbers listed in a certain display format; (xxx) xxx-xxxx.If I have the code such as this, it displays the unformatted phone number and (000) 000-0000 for the null items.

My Grid is bound to a collection type datasource. When I try to sort the Columns in the Grid I get Javascript error saying sorting event not implemented. Why is the default inbuilt sort functionality not working which worked fine when I directly used a sqlDataSource using smart tag. Do I have to write some code to achieve sorting ?
View 1 RepliesI have created a class file which gets me the state codes,license numbers and the expiration dates for the same.
I fetch the expiration dates in string format.
Each customer can have many licenses.
I have changed the format of the date (initially appearing as YYYY/MM/DD 00:00:00 when retrieved from database) to MM/DD/YYYY.
After retrieving all the licenses pertaining to a single customer, I bind them to a datalist.
Now the requirement is that for each customer, I need to sort the licenses according to the latest expiration date and then display the same.
How can this be achieved ?

I've just encountered an interesting problem in a standard BoundField in a GridView. The field is for EmployeeCode, which is purely numeric, but stored in a character column in the database. The DataFormatString="{0:00000}" attribute on the BoundField doesn't work, as I assume that format is only for numeric values.
To work around this, I had to use a TemplateField, and bind the text value using the attribute Text='<%# PadNumericString(Eval("EmployeeCode").ToString(), 5) %>'. Is there no simpler way of doing this?
I want to validate a textbox that only a numeric currency value can be put into it, for example 0.00. I thought the following code was correct but it doesnt seem to wrk, its causing an error on my page and when I remove it the page is fine, it doesn't actually give exact details of the error on the page just says "syntax error" in the browser that is all.

Basically, what I did is that: I have a table in SQL database and some of data fields allow null. I built Objectdatasource through dataset. When I built update page using dataset. It generate the following error before showing the update page correctly. It seems I have issue to retrieve the null value from the database through using objectdatasource through dataset. Any suggestions?An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code

View 3 RepliesFor efficiency's sake I've created a number of stored procedures to run against an SQL table. Which procedure runs depends upon the checkboxlist choices a user makes before clicking a button. The checkboxlist looks something like this:
<asp:CheckBoxList AutoPostBack="True" runat="server">
<asp:ListItem Enabled="True" Value="1">Item 1</asp:ListItem>
<asp:ListItem Value="10"> Item 2</asp:ListItem>
What I can't figure out is how to loop through the checkboxes in the Button1_Click event in the .cs code behind page to add up the values of the selected items. (The value of an unclicked box being 0.) Converted to a string, the totaled value is then appended to a stored procedure name (MyPROC) for entry into the SQL statement. In other words, if the user clicks just Item 1, then the Button1_Click event would produce a stored procedure name of MyPROC1, insert it into the statement, and fire off the query; if Item 1 and Item 3 are selected, then MyPROC101 would be called.
My second question is: how do I place the concatenated string into the SQL statement?
This might all seem a bit unorthodox, but given the number of variables going into statement, it seems to this newbie the best approach.
I am using Asp.net 3.5 listview control. In item_updating event I am using this code...
dim country as string = Dim country As String = e.NewValues("country_name").ToString.Replace(" ", "")
It's updating record correctly. for example if I update USA to USA 1 1 then it's updating like as it. But I want it to be USA11
