According to all I have read my DataNavagateUrlFields string should work but it isn't. The deal is that any one (AssocID) can have multiple AddrID's associated with it. Regardless of which I choose I only get back the first AddrID for that AssocId.
I have added a gridview in my aspx web page. I have added a hyperlink field, to navigate to another page from the gridview. I am getting the error as:
"There was an error rendering the control.
Index(zero based) must be greater than or equal to zero and less than the size of the argument list. "
This is the code i have used:
[Code]....
[Code]....
When i remove the hyperlink, the grid is getting displayed. I know, there is something wrong i have coded in the DataNavigateURLformatstring, but not sure what is wrong.
I want to pass the StudentID,CourseID,ChildImageID with the link as the querystring.
I have a gridview and I have an edit template for one control. I have a drop down box in this edit template so that you can select a value from it and then when you hit 'Update' the value from the drop down box is committed to the updated record. Unfortunately when I do hit the update button I get a fault that the "Status" field cannot be null.
Here is the code that picks the value from the drop down value and assigns it to the new values list:
I have a grid view that populates and displays data at btn click event from the following sql statement in one of the SP:
SELECT
reg_code, pc_serial, act_code FROM user_reg WHERE reg_code=@reg_code
I want to pass parameters to the other Stored procedure when the edit button is clicked in order to update the 2 columns in the specific row at the time. I now how to pass parameters in a regular btn click event or function, but in the case of edit btn in grid view I don't know how to capture data from specific row and then pass it to the SP. Here is Stored Procedure to update the columns (every user always has the same reg code, but may have more than one serial number and activation code, I want to let the user update serial number and then based on the serial number generate new activation code in the SP.):
[WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public string MyWebMethod(string foo, string bar) { // DataContractJsonSerializer to deserialize foo and bar to // their respective FooClass and BarClass objects. return "{"Message":"Everything is a-ok!"}"; } I'll call it from the client via: var myParams = { "foo":{"name":"Bob Smith", "age":50},"bar":{"color":"blue","size":"large","quantity":2} }; $.ajax({ type: 'POST', url: 'https://mydomain.com/WebServices/TestSvc.asmx/MyWebMethod', data: JSON.stringify(myParams), contentType: 'application/json; charset=utf-8', dataType: 'json', success: function (response, status) { alert('Yay!'); }, error: function (xhr, err) { alert('Boo-urns!'); } }); However, this yields the following error (a breakpoint on the first line in MyWebMethod() is never hit): {"Message":"No parameterless constructor defined for type of u0027System.Stringu0027.","StackTrace":" at System.Web.Script.Serialization.ObjectConverter.ConvertDictionaryToObject(IDictionary2 dictionary, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) at System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary2 rawParams) at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams) at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.MissingMethodException"}
I'd like to pass in two string parameters and use DataContractJsonSerializer to write new Foo and Bar objects. Am I missing something?
I am creating a Web Service, which will be used by a client to send data to our Database.The client will be sending close to 30 fields that will be updated to our table. If I write a Web method, I will need to have all these 30 fields as parameters to that method. Is there a better way than sending all of them as parameters?
I know how to pass parameters to Reportviewer in LocalReport mode via textboxes on the page where the user enters them and then they click refresh and everything works fine. What I cannot figure out is how to not pass parameters and make the report display everything, which should be the default.
I know I am missing something really obvious on the Report Parameters screen. Does anybody know the secret?
I am currently writing an ASP .NET (Framework 3.5) page that has a Grid View inside it.
One of the columns of this GridView contains only buttons, that if clicked should open a popup dialog.
To open the dialog I wrote the following code on the button's event handler:
[Code]....
Now when I click on any of the buttons the dialog opens just fine, however I need to pass some parameters to the dialog so that they can be displayed inside it. That's why I've encoded a Base 64 string and passed it as an argument of the popup dialog (apparently if I just used the plain string, the dialog would not open because the string contained linefeed characters).
Unfortunately I wasn't able to get the parameter (base 64 string) on the code behind of the popup dialog. How can I do this?
Below is my query string my page name is stored in data base when I am using without querystring its working fine, but when i am adding query string to it, its giving me error.. below is my code
In one of the web page say "Default1.aspx" I have a Gridview.I am using 2 DataKeyNames in Gridview. i.e., DataKeyNames="G_Name, Param_ID" Also, I have one Hyperlink inside Gridview, upon clicking, page navigates to other page say "Default2.aspx"
I have a parameter screen which contains many pop up windows for the parameters .
I have a department hierarchy which consists of department , branch and section.
I have 3 pop up windows for each parameter.
When i select, a department, it filters the list of the branch and shows only its branch when i open the branch pop up window.
But the problem is, when i select multiple departments, the branch pop up window shows the below error. The page works if only a department is shown.
Conversion failed when converting the nvarchar value '3,4,5,6 to data type int. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
I am trying to pass the value of a dropdownlist to the Update section of a listview. The dropdownlist is bound to one datasource which needs to then pass its selected value to the UpdateCommand sql for another datasource. Here is my code:
I want to generate crystal report in pdf format. I had done the same thing by passing one parameter. But this time I want to pass 10 parameter. I followed the same thing what I did for passing one parameter.
But now I got the Error Message "Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack."
I have a ListView displaying data from Table A using a SqlDataSource.
I want to take the displayed data (and these are just the standard columns representing fields in Table A) and store them in Table B using a Stored Procedure
(The scenario is much more complex but I've left out anything not relating to this exact problem).
I've added a Button to the ListViews ItemTemplate and I'm using OnItemCommand to create a Sub for its "Click" in the Code Behind.
This is a simplified chunk of the SQL I'm using to insert the ListView's fields into Table B using the Stored Procedure "InsertCart":
[Code]....
Where I've highlighted "Description" in the last line. In a GridView, this would be enough. Description is a Column name in Table A and B and iy's an Item in the ListView. But I'm realising that, with ListView's, the data binding is not as "automatic" as a GridView. Just using the columnname is not enough.
What do I use instead of the word Description to reference this column in the Parameter?
I have an ObjectDataSource3 that I am trying to use to insert data from:
From: Dropdownlist1.selected value To: (CustomerID) From: Dropdownlist2.selected value To: (ProductCode) From: txtTitle (Title) To: (Title) CurrentDate To: DateOpened The btnAdd event is suppose to calls: ObjectDataSource3.Insert()
Below is my code for both the page and class. Although my class is expecting parameters, I don't know how to get the parameters to the insert function in my class.
I am creating a grid with a code behind and in the hyper link column I would like to pass some parameters before passing users to a new page. If I just use one parameter, the CustomerID in the dataNavigateUrlFields and dataTextField then the
I have a number of drop downs that the client can select a range of criteria. From this, they will press a button, the query will be generated and low and behold, a gridview will be produced in a new window (or at least give that impression) bound by an object datasource. I would also like the user to be able to amend the search numerous times so they can generate a number of new windows/gridviews.
Now then..what would be the best approach for achieving this result?
My initial thinking was to create a querystring generated by the client criteria selections (in the drop down lists), a new page would then take the querystring and populate the gridview here. My concern with this approach is that the query string could be a whopper...are there any disadvantages to creating a ridiculously long query string?
Alternatively, are there any other methods or ideas people have used to produce a similar desired effect?
Unfortunately, when the new webpage opens, the url contains lots of spaces and I'm struggling to remove all of the spaces. The code actually works but looks a bit messy, see below.
I have 2 columns (name and address) in a gridview which are defined as linked buttons. Now when i click on a record in the first row (name) i am able to pass that value (selected name) to another page with rowcommand. Now i am trying to click on the second row (address) on a record but am not able to pass that value to the second page. Don't actually know how to define this in the code below. The first row (name) has to redirect to one page (this what i have already accomplished) and the second row (address) has to redirect to another page
