Data Controls :: Slow Loading Page In Primary Key For Next Loaded Data - Primary Key Not Show Properly
May 7, 2015
I am working on lazy loading page the problem is
when i bind first time page (10) records then primary properly bind with records and when my next 10 records load using lazy loading then the primary key not change it shows 1st records primary key
check the below code in which i am assigning assetid (primary key) but its not assigning properly...
function OnSuccess(response) {
//alert('testing');
var xmlDoc = $.parseXML(response.d);
var xml = $(xmlDoc);
pageCount = parseInt(xml.find("PageCount").eq(0).find("PageCount").text());
var customers = xml.find("AssetSummary");
adID is the primary key (Advert) and acts as the foreign key for Student
I have two pages, both of which each have a detailsview in insert mode
what I want to achieve is to create a new record in advert.aspx (e.g. adID = 4), then when item is inserted, redirect to page student.aspx (which a student record is created) where the foreign key is the ID from the advert just created (e.g. student.aspx?adID=4).
i get the following exception (missing primary key) in the line of using Find() method "Table doesn't have a primary key." I've rechecked the Database and all Primary Key columns are set correctly.
DataTable dt = p.GetAllPhotos(int.Parse(Id)); DataTable temp = new DataTable(); temp = dt.Clone(); temp = (DataTable)(Session["currentImage"]); DataTable dtvalid = new DataTable(); dtvalid = dt.Clone(); DataRow[] drr = new DataRow[1]; drr[0] = dt.Rows.Find((int.Parse(temp.Rows[0]["photoId"].ToString()))+1); foreach (DataRow dr in drr) { dtvalid.ImportRow(dr); } dtvalid.AcceptChanges();'
In the database one number like a 91-9685748596 and, 2nd number like 9122-9685748596 and another one is 9685748596 .when we are try to formate it using substring function it all are may be9685748596,9685748596,9685748596.Mobile number is assigned as a primary key.so its showing error "Primary key violation".We can not the remove primary key also and there are 50 lack data in our database.
I would like to know If I can Get the Primary Key of the Selected Row without display the PrimaryKey Column? I Created a S.P which return me a DataTable of the Customers Tables (There Details only, without there ID which is the Primary Key) I set it to GridView for Display the Customers list. Now, I want to get the Selected Customer ID (His Primary Key) How can I do this? I tried to set the DataKeyNames of the GridView to "CustomerID" But, it didnt recognize me CustomerID. what to do, to fix it?
I have 2 GridViews. One is working perfectly. What I would like to have happen is when a row is selected on GridView1 (with Primary key of OrderNumber), the matching records from the field in GridView1 ClientID to show up in GridView2.
[Code]....
I think I've narrowed my problem down to CilentID is not a primary key, but still there should be some way to link them.
name | phno. | emp_name(in dropdown) | buttonfield
wen user comes on this page this grid comes filled but then I need to select 1 emp_name from dropdown and click button(in last column) corresponding to that row. then on clicking that row button it should fetch that toq Primary Key and dropdown corresponding id. how? Wen I m fetching its fetching row index as 0 though it is no.4 record as per database(coz my records are in desc.order). I mean its giving row index as per grid and not as per my actual table(primary key).
I was wondering has anyone ever had a requirement to show the Primary Field Id value in a form when it Loads? I notice that in SQL Server there is no visible value assigned to the Primary column until you enter the data in all the fields and then move to the next row. Is this value stored somewhere internally so that I can show it on the webform to the user?
I have two gridviews, where the first is databound to a sql table (but does not display the primary key info), and want to filter the data displayed on the second gridview by using the primary key info from the first gridview table, indicated by the selected row in the first gridview - how I could achieve this? its kind of like using the gridviews as a menu and sub menu display!
I have a textbox that takes an integer value, and a submit button that when clicked passes the value to a detailsview to display the database record at that index.
What I'd like to do is, when the button is clicked, compare the number to the keys in the detailsview's datasource so that if the record ID doesn't exist, I can display a label telling the user that the ID# doesn't exist.
How would I go about doing this? Is there some sort of compare method for the datakeynames property?
I'm trying to create a Formview in ASP.net 3.5. The underlying SQL Server table does not have an identity field based Primary Key. The primary key is a 4 character user entered field. I have created the form and all looks good but I get the following error message when I try to insert a record
Could not find a row that matches the given keys in the original values stored in ViewState. Ensure that the 'keys' dictionary contains unique key values that correspond to a row returned from the previous Select operation.
I thought ViewState was supposed to resolve the issue. I have viewstate enabled on the page and the formview but that doesn't seem to make a difference.
How can I create a form view with a user-entered text field as the primary key and get the b.... thing to work?
I have a table with primary key whose importance is technically high and none business wise. So, when I display the table data to user, I would like not to show him the primary key. Even if I load it in sqldatasource and dont show (I did this by removing the cloumn in "Columns" tag of GridView), I am not able to update or delete row using the built-in UpdateCommand & DeleteCommand. I have created the delete paramters but it does nothing when I hit the delete button.How to get around it?
If I am passed a datatable and I cant change the column structure..is there anyway to set an existing column to a Primary key so I can easily Find() the row I am looking for?
I am using Visual studio 2010 express and I have a details view databinded to an sql database table. When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?
Using a very run-of-the-mill database, with identity int for primary keys, a Dynamic Data Entities Project (EntityFramework) displays the primary key for view and edit. When using Linq to Sql, the primary key fields are not displayed.
I would like to hide the primary keys and use Entity Framework (VS 2008, .Net 3.5 sp1).
I have an .aspx page with multiple .ascx (User Controls on it). One of the User controls is very slow in loading (calls a very slow webservice for the data.). Now, my question is how to render all the controls on the page (so the User can view those) and have a rotating icon for this control (slow one) (till it loads). I know, I need to bring AJAX into picture, but any clarification on that would help as I will be new to AJAX programming.
