Forms Data Controls :: Can't Convert Values Of Parameter
Feb 9, 2010
I have a problouw with a listview connected to a object datasource, when I try to edit a record and hit the save button without changing anything I got a error : Cannot convert value of parameter 'BirthDate' from 'System.String' to 'System.DateTime' The birthdatevalue is presented in a masked textbox, my data access layer is not reached so the error is in the listview itself How can I edit date values in a listview?
Singles and suppers are money fields for the price of same item. A bit like the price of a Small, Medium or Large item. What I would like to do is display the 'Singles' price and 'Suppers' price in seperate listitems so the user can choose 1 of them.
GridView: Traditional Name__________Size Chicken-------------------[DROPDOWNLIST]
DropDownList: Price of Single is: £1.50 Price of Supper is: £2.50
My page loads up with the correct items in TraditionalName colum but the DropDownList is completely empty. I'm aware I don't have anything in for DataValueField and DataTextField but I have tried putting things in these attributes, like Suppers and Singles, but nothing works, so I have taken them out below.
I have a GridView control with a header template with Text Boxes so users can input new data for a new row. I need to bind the text property of each TextBox in the header row with the insert parmaeters in my ObjectDataSource.
I have a Detailsview grid with an SqlDatasource, this DVG is only going to be used to insert records. The primary purpose of the DS is to populate a DDL control in the insertItem Template that I created my code is this:
[Code]....
The DDL control populates correctly, but when I try to modify the INSERTCommand property in my DS, I try to assign the value to my parameters "TesterID" and "TesterDate" but the only options for controls to pick from, is the DGV but not the DDL in it. I assume it has to do with the InsertItem template but even if I reset it I still cannot pick the textbox as a control that would give the value to my parameters.
I did find a workaroun by build a public method and calling it in the onclick event of the insert button but looks like I have to create another connection to the database which to me seems unnecessary since I already have a DS and everything. how can I do this without having to use my method. here is my method just in case.
I have take a datagrid view and now i want to update the records as the database is been normalized i need to enter the multiple rows at once. How you I convert the datagrid to enter the data so that it would be easy for me to update the records?

The logic here is, the user should login first in order to retrieve his/her album. when the user is logged in, im retrieving the 'userid' and using it as parameter to load the corresponding album from the database.
when i login and open the albumpage, im end up with this exception:
"Failed to convert parameter value from a String to a Guid".
What could be the reason and how can i avoid this exception.
by the way im using the aspnet_Users table's userid field.
When running our web application the following message appears:
Failed to convert parameter value string to decimal. We believe that the problem might be with the sequence which generates the user_id. The user_id should be the output after successful insert of record. The stored procedure works well from within the DB and Visual Studio. Our DB version: 11gR1 on Windows.The web form has a button event with this c#-code:
How do you use the http POST method with a Grid View on another page. I am trying to use the POST method to send the ID from the selected row of a Grid View, I am using a link button set to fire the select command and it has the Post Back URL set, from one page and then retrieve the ID value on another page using an Object Data Source. Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.
The Company table contains any Company with a potential relationship to a "Member". For example:
Companyabc = C (Competitor) Companyxyz = S (Supplier)
When a new Member record is entered, the user selects from two dropdowns: CompanyType (Supplier, Retailer,Competitor); and CompanyName. The CompanyName dropdown is populated depending on the value selected for CompanyType so if the user selects "Supplier" for CompanyType then only those Companies with a CompanyType of "S" for Supplier will be listed in the CompanyName dropdown.
The use can enter up to 10 CompanyType/CompanyName combinations. When the record is saved, these CompanyType/CompanyName combinations are saved in the Member_Company_Link table. One record for each CompanyType/CompanyName combination is entered in the table.
The problem I'm having is in the retrieval process. I have a "search" screen in which users can select certain criteria to list Members by and one of them is CompanyName. For example they want to see all Member records with "company xyz" as a Supplier and/or "companyabc" as a Competitor. Because each Member can have multiple Supplier and/or Comptitor records I can't figure out how to loop through them to match on the value entered by the user. If Member1 has 5 corresponding records in theMember_Company_Link file and 4 of them contain Companies that are Competitors (Competitor1, Competitor2, Competitor3 and Competitor4) and the search criteria is to find records containing "Competitor3" how can I loop through the values in the Member_Company_Link file for each MemberID to see if there is a match for "Competitor3"?
I know this post is too long and most of you will have ignored it by now but I'm hoping someone will have a clue because I've already spent more than a day trying to figure it out. It seems I have to store multiple values in an array but I have no clue how to do this.
I have am SqlParameterCollection and an arraylist. I want to be able to loop around both of them and take the SqlDBType of each parameter in the collection, and convert the value of the arraylist to the data type of the parameter.

I'm using a GridView control to edit data in a MySQL database.
I've created the C# code behind but I'm having trouble pulling back the parameter from a radiobutton control to populate an Int32 field in the database. I'm getting "Input string not in correct format"This is the particular bit (amongst a host of others of the same type) that is causing the problem:
I have written a code to insert emp details into database and i am also inserting local date(i,e system date) into to the table to know/have an idea at what date the employee inserted details. I have set date format add/MM/yyyy and its working well in my local system, but after uploading the site into server (the server is shared server) iam getting error and the error message is Failed to convert parameter value from a String to a DateTime.
Surprisingly, it is working well in server when i chaged the date format to MM/dd/yyyy, but now its not working in my local system and getting the same error.
