AJAX :: Why Is Datagrid Not Visible After Data Is Loaded forums.asp.net

My initial page load takes atleast 30 secs, because the gridview's datasource takes that much time to get the data from a webservice. My webpage also contains a text box and a button along with the said grid. The text box is populated when I click on "Select" link on each row with the datakey of the row. I want to accomplish 2 things 1. During the initial page load, I want to display the empty text box and button and hide the gridview by showing an "loadin" image in its place. 2. Once the data is loaded in the gridview, the gridview should become visible, and subsequent "paging" and clicking on "select" shouldnt make the "loading image" visible I have implemented the following code [Code].... Here is the page load method in code behind. The loading image shows up initially as expected on page load. but once the data isloaded the gridview doesnt become visible!! why? [Code]....

Forms Data Controls :: Forms (text Boxes) And A Gridview On The Same Page forums.asp.net

Really getting better with VS, but I've mostly been displaying data. I'm on a new project and now and I have a lot of data entry forms to create. I created a form to enter data into an access db and got it working. I thought it would be cool to add an edit button that fired a gridview to load on the same page, under my original forms, so that that they could load up the data and edit or delete mistakes. But when I try to update the gridview, it also tries to post the original forms (text boxes), which fail because there is no data in them, and I get an error. What is the proper way to handle this in asp.net? I'm sure this is kind of a common issue. I've done some searching, but the search terms, like forms and gridview, are kind of generic and I'm not coming up with anything useful. I just need a more experienced person to point me in the right direction and I'll get it figured out.

Session Object Design Pattern? stackoverflow.com

I'm looking to build an ajax page; it's a reporting page. By default, load today's report. On the page there's a calendar control and when the user clicks on a date, reload the gridview with the corresponding data. Is it considered good practice to do the following: 1) on the first page load, query the data for the page 2) put the query result in the session object and display it in a gridview 3) if the user requests new data, get new data from the query with different parameters 4) put the result of the second query in the session object and display it 5) if the user then requests the data from the first query, get it from the session object 6) do the sorting and paging with the data held in the session. Note: the data of each query will contain about 300-500 rows and about 15 columns. I'd like to do all this with ajax calls. What are some suggestions and pitfalls to avoid.

I am using a sqldatasource for filling one GridView and on page loading or before taking any action, there is no data (default value=null) and normally the datagrid is empty (using emptydatatext="no records found etc etc...").. Issue is I can not see the header of that grid in empty case, but only the emptydatatext! I have tried to use some code of the references below, but no success, because I'm not using DataTable control as a DataSource, but directly filling the gridview from sqldatasource! useless references: [URL] P.S. I'm not usign DataTable as a DataSource, but sqldatasource (from the Data Controls), and I want to show header, when sqldatasource is null or empty ?!

Web Forms :: Asynchronous Loading User Controls? forums.asp.net

Web Forms :: Multiple UpdatePanels With UpdateMode="conditional" Cause EventValidation Exception forums.asp.net

I have 2 UpdatePanels in the same Page, and each one contains a GridView with some datta. I am using UpdateMode="conditional" because i only want the GridViews to be Filled when needed. So the data in each GridView is loaded only if the user asks for it, and it's not loaded again unless you need a change in the grid (sorting or page changing). GridViews are filled with data from a DataBase, but I only read the data from the Database when needed. So, in first Page_Load, any data is readed. If the user wants to see the data in GridView1, the data in GridView2 is not loaded from the database, and viceversa. My problem comes in this situation: User enters the Page. User ask for the data in GridView1 (UpdatePanel1 does the job) User ask for the data in GridView2 (UpdatePanel2 does the job) Now, the user can see both gridviews in the page. If he tries to change the page index or to sort data in GridView2, everything goes fine. The problem comes when he tries to change the page (or sort) in GridView1 (because in the callback to retrieve the data to GridView2, GridView1 was not filled, so the data the user is seeing is there because of a previous callback). The user gets an Event Validation Exception, and i don't know how to avoid it. I think it's because the server "thinks" that GridView1 is empty, because of the callback to load data to GridView2, where GridView1 was not filled.

UserForm ListBox Being Double-loaded www.excelforum.com

I'm having problems loading data into a listbox. When the form first opens, it loads the data twice. I can then kill the form and restart it and the data is in there three times. I can't see any loading problems with the userForm_initialize routine. How can I ensure that the listBox is empty before I start adding data? This would also seem to be necessary prior to loading a different set of data into the form - correct?

Forms Data Controls :: Repeater Containing Gridviews? forums.asp.net

I will have a master data set (populated on page load and persistent over postback), containing all the data I want to display, with an ID for each gridview section (each row will also have a uniqueID for that row). I will use a repeater that will repeat on a list of those IDs, and on each ItemDatabound I will extract the data from the master dataset, into a temporary one (local to that method), filtering it on the repeater item's ID and populate the gridview. I have got this working, but now comes the part where it may fall apart:- I now want to add text boxes and dropdownlists, plus checkboxes (see later) to certain gridview rows on the grdview's item databound method, these (apart from the checkboxes) will cause a postback on the data change (either text changed or selected index change) and this will update the master dataset item, based on the UID for the gridview's bound datarow. There will also be a button in the gridview header that will scan that particular gridview's rows for checked items, and then update the master dataset, again based on the gridview bound row's data UID.

Qestion About SQLDataSource, Gridview, And Update Panel forums.asp.net

I have a gridview that is tied to a SQLDataSource control which is inside an update panel. What I'm trying to accomplish is when the page is loaded the gridview is filled from the SQLDataSource. I have some textboxes also on the page so that the user can add new items to the gridview. The update panel trigger is tied to my code behind page through a button click which added the new data to the DB with an INSERT statement. Since the gridview was inside the update panel I thought when I placed the new data into the DB and the update panel caused the portion of the page that holds the gridview to refresh that the gridview would show the newly added data but it is not. I am missing something but I do not know what. I tried adding a gridview1.databind() and SQLDataSource1.DataBind() but niether caused the update of the gridview as I had hoped. Thanks for any of your help. Ty

Forms Data Controls :: Reading A GridView Which Has Text Boxes? forums.asp.net

Forms Data Controls :: Check Whether Data Has Been Modified Or Not In User Controls? forums.asp.net

I have 5 user controls in a web form. Data is being loaded into the user controls at the user control page load event. I have a single save button for the entire web form(the the top of the page). Each user control has update panel and consists of many web controls like textbox, dropdown,gridview and many other. after the page has been rendered successfully to the user. Considered that he has changed text in one user control ( in few textboxes,dropdowns , grid) and clicked on save button. Now I should save only the changes user has made ( in 1 user control) instead of saving all the 5 user controls. how can i achieve this?

Data Conversion Prob www.vbforums.com

I am currently working on implementing a Encryption-Decryption Prog:Encryption Form:->Plain Text converted to Ascii form using StrConv(plain, vbFromUnicode)->Encryption carried out after padding->Cipher Text converted to Unicode using StrConv(str, vbUnicode)Decryption Form->The above Cipher Text converted to Ascii form using StrConv(cipher,vbUnicode) (Prob: DATA LOSS HERE! )->Decryption carried out + Unpadding->Plain Text converted to Unicode.Does the StrConv function really cause data loss? I removed the last step of 1st form & 1st step of the 2nd forms ..ie took the cipher text data in ascii form itself & there was no data loss then. Finally i got the Decrypted plain text to match the original data.The VB program allows the user to encrypt as well as decrypt or test the encryption also.The user might take cipher data from a text file itself. Hence the decryption prog should be able to operate on its own & cant expect data to always be in ascii form So my question is: How do i carry out Unicode to Ascii conversion without data loss?Or the only way is to make output of Encryption = Hex or binary form

I want the user to be able to change the text in the textarea and click update, which will update the database to the new text entered.

Forms Data Controls :: GridView Sorting, Paging And DataBinding / When Control Causes A Postback GridView... forums.asp.net

I'm trying to extend the GridView control to enable sorting and paging for any situation. When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach? To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView. Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView. My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable. The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below, [Code].... I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.

Custom Server Controls :: Extended GridView.Rows Collection Always = PageSize Even On Last Page? forums.asp.net

Using VS2005, VB code behind, I am extending the GridView control to include a custom pager for a custom paging scheme (only one page returned from the database at a time rather than all records). In my testing a discovered an issue - on my last page of data, the GridView's rows property always returns a collection of PageSize page, rather than the actual number of records on the page, with non-data fill records being empty rows. For example, suppose I have 23 records in my database. Assuming a PageSize of 10, when I page to the last page of data the gridview it properly displays the last 3 recrods - but when I handle the GridView's CommandName="Select" event the GridView's Rows collection contains 10 records, the last seven of which are empty. I set a break point in just before I call GridView.DataBind and verified that the DataTable used as the DataSource for the last page of data does in fact only contain the 3 expected records. But when I set a breakpoint on the Sub that handles the "Select" GridView command, the GridView.rows collection contains 10 records, the last 7 of which are empty. This post[URL] and comments make note of the issue but the solution prescribed by the author does not seem to work. Attached are some snippets of my extended GridView and the two methods from my page where I mentioned setting breakpoints above. Snippets from my extended GrdiView [Code]....
