DataSource Controls :: How To Implicitly Convert Datatable To String
Jul 30, 2010
I'm having a problem with reading a string from sqlserver database and use it as the text of a label,
getDescTableAdapter gd = new
getDescTableAdapter();
Label2.Text = Convert.ToString(gd.GetDesc(pid));
what i get in the form is: getDesc ! everything is right in the dataset and if i bind it to a gridview it works fine but when i convert it to string it seems it converts the table adaptor's name instead of the value.ance
I want to log all errors happened in my App to sql db. I'm passing all exception properties like (ex.Message, ex.Source, ex.StackTrace, ex.TargetSite and ex.InnerException) to stored procedure.
The problem is that when I try to pass the ex.InnerException as string to stored procedure I got this error:
Cannot implicitly convert type 'System.Exception' to 'string'
I tried ex.InnerException.ToString() and Convert.ToString (ex.InnerException) but no success.
I have a products table with 3 fields name, price and quantity, I need to fill a datatable with those 3 fields and using a foreach build a chain. I build my chain currently using a datagrid with my following code
this code work good.
string item_name; string amount; string quantity;
[Code]....
but I like to form my chain directly from datatable, not rely on a datagrid.
I have store procedure which return result set. I have used LINQ datacontext object to get the result set from this store procedure, which returns the result set in IsingleResult format.I bind this IsingleResult to my gridview.
I want to convert this IsingleResult into DataTable format so I can sort the gridview.
I have a datalist which querys the database and pulls the data ApplicantID, date, and testimonial into the datalist. I now want to get the username from the ApplicantID. Im using TLists to do this but on the line ApplicantDetails = JustClick.DAL.DataRepository.ApplicantProvider.GetByApplicantID(ApplicantID);
im getting the error cannot implicitly convert type on datalist can anyone help as to why and how I can fix this cheers. The code im using is below
this is the web method I'm using to convert my DataTable into JSON string:
[Code]....
But I'm not sure this is as good and as fast as it should be. I am sending to client side a JSON string format, but I think maybe there is a better way of doing this. I know there is JSON.NET
but I didn't see there any converting for DataTables.
I need to limit the length of the string that load into a DataTable that is being used to display. The data I am loading is coming from another DataTable. How do I shorten row["CG_GalleryName"] contents to 24 characters.
Convert.ToString(row["CG_GalleryName"]) -- how do I set this length to 24 characters? Using it in the below code.
q="select convert(char(8),datecol1,112) from tblone where datecol2 is null"
is what I use for my query string for sqlcommand(). I'm getting the error "a field or property datecol1 could not be found in the datasource". Without the convert, the query is ok.
the problem is when I use debugging mode, I mean using with visual studio, it's going fine. But when I call from IIS there has a error.. Unterminated string constant. I know where is the problem
I'm having a asp.net listbox on the front end webform with multiple selection, after user selecting multiple items, i'm capturing the DataKeyValue of listbox(which is amenity_id of bigint) and looping all the selected items to a string with comma sepearated values. For example if user selects first 4 options, my output string will be like this (1,2,3,4) and i'm passing this as a string type to my data access layer and then to my below stored proc. I'm geting this error while inserting.. i know that my data type is of bigint and i'm trying to insert string type. i need to convert the string type to INT type and insert data. below are my stored procs:
[Code]....
This is where i'm splitting the comma seperated values and inserting them into table.
so i have the function below in a webservice. and it works, but when i try to copy it to aspx page code behind, i get the message in the subject. Can someone tell me if the function below is valid? One of my project uses it and it works.
