Forms Data Controls :: Getting Data Does Not Correspond To Valid JSON Error?
Apr 14, 2010
I have an Infragistics WebDataGrid on a user control. I add that user control programmatically to an UpdatePanel on a Content Form. Everything works great. I get data in the grid just fine. However, when I go to click any of the grid functions (Sort, Filter, Page, etc.) it throws a Sys.ArgumentException in one of the ScriptResource.axd dynamic files.
Here is the error:
"Microsoft JScript runtime error: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON. Parameter name: data"
It stops in the following function:
[Code]....
I read about other people having this issue and they said it was due to dates or due to double quotes ("") being in strings? I am binding this datagrid to an Entity Data Framework object query like this.
I'm using Sys.Serialization.JavaScriptSerializer.deserialize to deserialize the json. unfortunately I got an error saying that my data does not correspond a valid json.

I need you assistance, Dynamic Delete LinkButton with CommandName=Delete gives me an error: Delete can only be called on a valid data item. nfact I am designing a Complex Grid using .Net 3.5 ListView Control with Scrollbar and Fixed Toolbar: This grid consist of 3 Tables:
1- footer 2- Toolbar Control 3- Scrolling Data Grid with Header
ListView give us only one ItemPlaceHolder to Bind Data as per LayoutTemplate, so I cannot able to manupulate my Toolbar Controls with ItemTemplate :(, therefore I decide to use ItemDataBound to add ImageButtons Dynamically using Init Page Event and I am able to get the result as you saw above:
ImageButton with funnel icon is with CommandName="Filter" ImageButton with magnifier icon is with CommandName="View" ImageButton with stop icon is with CommandName="Delete"
Now I can able to handle Filter and View with OnItemCommand Event but when I click Delete button I am getting an error as shown below: The grid used CSS I am sending you the HTML and code behind to resolved this problem: HTML CODE:
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.
I am having trouble formatting the date on a textbox I get the error above if I don't enter the date in MM/DD/YY format in the textbox. I am also using this in a FormView so I can't format it or don't know how to in the code behind so if there is a way to format it in design view that would be preferable. Does anyone have any ideas on how I would do any of this.
I want to filter a Gridview by date. I enter the date in a textbox and use FilterExpressions. I keep getting the error message: String was not recognized as a valid DateTime. How can I solve this?
I'm populating a DataList using the IDataReader object and it works fine it the reader contains data. If the data is not present it displays nothing. I want to capture that situation and insert a verbiage such as "No data" or something like that. I've tried to test the datareader for various conditions such as Null, String.Empty, or plain " " but nothing worked. Is there a way to make this happen? Below is my code sample for your review.EJM.Note: It has to be done programatically as I'm building this for a web part.
There is select and update SQLs in sqldatasource and checkbox in formview which is 2way databinded to an sqlserver bit field type.
