Forms Data Controls :: Passing Multiple Parameters In Hyperlinkfield In Gridview?
Dec 26, 2010
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 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
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 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 have a gridview with a hyperlinkfield inside of it. There is a dropdownlist that re-databinds the gridview onselectedindexchanged. I'm using the datanavigateurlformatstring attribute of the hyperlinkfield to make the url, and in in most cases it works as it should. HOWEVER, when one particular item is selected from the dropdownlist the associated links that are supposed to be created in the hyperlinkfield do not work. They arent actually clickable. In the source they have no href (which is what the datanavigateurlformatstring is supposed to set along with datanavigateurlfields). I have debugged to see that before and after databinding the information going into the control is correct, but still it doesnt work. In every other case it works.
