I have string. There are no items to show in this view of the "Personal Documents" then assign to string str variable string str ="There are no items to show in this view of the "Personal Documents" library" Now planning to replace "" and make it to actual string to str object. I tried below, but did not worked
str = str.Replace(@"",string.Empty);
I want str value should be string str ="There are no items to show in this view of the "Personal Documents" library" I need to find this string in another string. While searching into that string. I couldn't found because str contains "".
If I have JSON like this and pass it to the engine I am using to create a PDF file, the word "null" appears on the PDF. This isn't really my example, but I googled "json replace null empty string" and this was a hit, which is a good representation of my data, also:
We use a rendering engine that creates a PDF from a fixed template and variable data in the form of a json string. But our customers don't want to read that the id is "null", they want to read that the id is blank. In my C# program, the json is just a string, so I can easily do something like this:
jsonString = jsonString.Replace("null,", ",");but the issue is I can't replace null-comma with a comma, because then it's invalid json.
how to I make the rendering engine *and* my customer both happy?

This is completely frustrating and probably embarrassing as well. A while back I posted a similar question and resolved the issue. [URL]...scope_identity The program has been working ever since, until yesterday when as it turns out SCOPE_IDENTITY() started returning an empty string even though a record is being inserted. I am not sure what has changed since the fateful day.
I am hoping that there is something I am just not seeing here. A lot of the information I have seen thus far indicates that there are problems with SCOPE_IDENTITY() but most of those are related to inserting multiple records. As you can see this should be fairly straight forward. The thing that really has got my goat is that it used to work and now it doesn't. If someone could take a look at the above code and comment on any anomalies it would be great. Also I have heard suggestions for switching to ADO.NET and it is beginning to look a lot more attractive every day. But I have a ways to go before making the switch so it is SqlDataSources for now
I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
In my detailsview, I have an emptydatatemplate set up to allow users to enter new records. The code works. However, once the record is inserted, the detailsview defaults to a standard insert screen. I know this will cause confusion for the users. I would prefer the detailsview to either show in edit mode or a read-only mode. I have used detailsview.changemode and detailsview.currentmode in the custom sub created for the add new button of the emptydatatemplate- neither of which do what I was hoping. It would be even better if when there was no data, it defaulted to the insert screen (which seems like that should be an easy, no-brainer way for .net to function) but it doesn't. Or, I don't know how to accomplish it.
I don't want to force the user to click cancel after inserting an item through the emptydatatemplate just to be able to use the detailsview for other records.
I use GridView & FormView to update a record. but when I click the "save" button, throw an except : FormView must be in the insert mode to insert a record. The record has been updated success, and I didn't change the mode of the FormView, how this error comes?
I have a problem that if I pass a string that contain + in a query string and try to read it , it get the same string but by replacing + with empty charFor example if i pass query like ../Page.aspx?data=sdf1+sdf then in page load I read data by data = Request.QueryString["data"] it will get as below data ="sdf1 sdf" I solve the problem by replacing any empty char with + .. But Is there any problem that cause that ? and Is my solution by replacing empty char with + is the best solution in all cases?
I have a FormView with a byte field. The field is not required and if I don't enter a value, I get an error that the value is not acceptable in a byte field. I can replace the null value with 0 but I would prefer not to.
What is the best way to handle this so that if I do not enter a value in a byte (or int16) field to insert a null value (or whatever they do in the ASP.net).
so that the resulting output does not contain words at the centre.In the above code instead of giving the word vocation exclusively, i have to mention some pattern, so that it will replace all the words instead of doing it for first sentence only.How to modify my code?

I should probably post this question to a different forum but I've had such good luck on this one, I hate to leave...I have an SQLDataSource which has a concatenated field of FirstName + ' " + LastName AS FullName. That datasource is used to populate a Primary Contact combobox in the GridView based on the dsOrganizations datasource. ComboBox datasource = dsContacts, TextField = FullName, ValueField = ContactID, ValueType = Int32 nfortunately, not all the Organizations have Primary Contacts listed yet so the above substitution breaks and doesn't even show the Primary Contacts when they existWhat I need is someway to either leave the Primary Contact row blank in the DataGrid or replace it with "[none selected]"
