Forms Data Controls :: Find Value In Previous Row Of GridView_RowDataBound?
Oct 26, 2010
Using vb.net/asp.net 2005.
In the gridview_RowDataBound event I am trying to find out the values from previous row but its giving me an exception. does anyone know how to do this? I need to do this because if the value is the same then I need to hide certain columns.
I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.
The code was working correctly until i used a master page.
R.aspx vb Code: Dim athUsr As New AuthenticateUser() athUsr.IsLogIn("~/Login.aspx") If (IsPostBack = False) Then Dim objcoll As UserRegistrationColl objcoll = UserRegistrationProvider.GetDynamic(Nothing, "UserId='" + SessionManager.UserId.ToString + "'", Nothing) [code]...
I am developing a web application in ASP.NET3.5 with C#. I also using Telerik RadAjax Control. When user click the menu then open the page with a new tab(Like web Browser).I want to create, when user back any previous tab(page) the will be show the previous data without loading 2nd time( like browser tab). Is it Possible ?
I am trying to build myself a grid that displays some very simple data (a name and a price of food items on a menu) which the user can very easily edit. The idea is that the grid is always editable, and editing, deleting, adding a new row and hopefully swapping two rows can be done without posting back to the server (at all, not even in an update panel or something).
So far I managed to get deleting to work, but it requires a bit of an explanation. I have a pretty good idea of how to implement adding new rows so I will try that myself. The problem at the moment is swapping rows.
First of all, the data I am displaying in the grid are instances of the MenuItem class, which has properties:
Id (integer, unique identifier)Name (string)Price (float)
I have a Datalist in which i m entering values to form a shoping cart. so when a select the check box the respective value goes in into the datalist and now if user again select that checkbox and submit i cant to check that is their any previous enrty with same name because it is a unique row in the datalist.
code:
[code]....
this is creating an error if if newly added row is already in datalist...so plz find me a way to check the new row with already present row and i have also set the primary key to table also.
I am using a Gridview binded to a LinqDataSource that represents a database view. The gridview paging is enabled. When navigating from page 1 to page 2, it displays the right count of rows in this page (assume pagesize is 10 and page 2 should have 4 rows only to have total of 14 rows in the view; the datasource), however, it populates wrong data (from the previous page). On the contrary, when I disable paging, everything works ok.
I have datagrid. i loading data to grid from user control like below
[code]....
when i click the button Show child item. all the child item are displaying except one. for first child item not displaying, but one of parent items is displaying inside child grid.
it seems like previous parents data is loading to one of child record. How can i prevent that?
I have a Timer and a GridView who pulls info from the database every X seconds.Every time I query the database the field 'Comments' is replaced with whatever is on the database (since it's bound to it). I'd like to keep my previous value and keep adding into my Label the subsequent values queried from the database.
For instance, first time I query I get a value of "1" in the Gridview. Now someone changes the database row and next time I query it I have a value of "2". Well, I would like to concatenate the last value queried with the previous one and so on.
So at this point the GridView should show "1" and "2". Here is the piece of code I am talking about:
I have to create a customized Next/ Previos solution, the DataPager is not flexible enough for what I want. This is what I have so far.
1. A user does a search and 100 records are returned, I have 25 records per page and so get 4 page numbers -- this is already done on search.aspx
2. The user clicks their choice (let's say its 'Post 10') and is taken to that record on details.aspx -- pretty standard stuff.
What I now need is a Next /Previous links on the details page -- so if the user clicked Post 10, on the details page will be two links, Next linking to Post 11 and Previous linking to Post 09. (i'll actually be using the post title as the text in the links not simply Next/Previous) I'm unsure about how I should begin to struture this, should I be looking at creating Temp Tables in Sql Server and step through the records or can I access the dataset from the search page and step through that?
I have a "search page" where the user enter some search criteria and a gridview where I display found records. When selecting "edit" on a row I open a second form to allow editing the found data. When the user click close button on the second form I want to go back to the search page. From the beginning I did just return (redirect to page 1) to the page but now the users also want to retain the search form with the serach criteria and found rows (also refreshing the found rows with possible changed data).
I can not just use a javascript with "history.back()" since the edit page might have done postbacks so that will not return to search page.Of course one solution would be to call the search page with a query string (or other ways to pass data between pages) containing the original search data but that solution might get messy.
Site basically has datbase results which can be sorted on a page. each record in the recordset also has a link to a Detail Page with more information on that item.
I would like to put some links "previous" and "next" on the details page so that a visitor does not have to go back to the results page and choose the next item in the list.
I've seen this on other sites but just can't seem to grasp it. Database results are done using ASP.NET
Anyone have any pointers? or if you have an asking price I'm all for that as well as long as I learn from it. I can provide url and code if needed.
I have a page where I am displaying a series of 10 items that are each links. This data is fed from a database. I need to add a previous and next function to this page but I cannot use any of the data controls in ASP.NET. I need to grind this out manually.
The page iterates through a recordset of up to 10 records and formats the data and inserts it into the innerHTML of a div on the page. What would be a good method here for implementing a previous and next function without using the GridView or other data bound controls?
I have a search page. If a user enter something into title textbox and search let say it display 15 records.
If click the title of each records, it goes to DetailsPage.aspx.
What I want here is: If user click the title details of a record and leave that search page, I want to put there(On Details.aspx) Previous/Next button arrow so that the user does not need to browse back and see the search results and go to next details.
Note: I am passing ID into querystring when go search page to details page.
How to keep remembering IDs on details page of searched records on search.aspx ?? Use session or something different ? How can I do this ?
I have done some modification and customization with List.aspx under Dynamic Data.
I must have messed up some controls or events somewhere.
Everything works well except that GridViewPager buttons (|<, <, >, >|) does not bring me to the next or previous page. It stays at the same page.
But if I manually type in the page number into the page number field and press enter, it works brilliantly. The gridview refresh to the correct pageindex.
I want to show First , Next , Previous , Last Buttons all the time in gridview if i am last page then disabling the Images. But i want dont want to hide the images.
I have a dorpdownlist in a gridviw template column in asp.net page.
I have applied few checks after dropdown_SelectedIndexChanged event and if the new value doesn't meet the needs then it should get that previous value that it had.
The delete link on my gridview deletes the previous row instead of selected row....Also, it doesnot delete the already existing rows. When I add new rows and try to delete them then my delete works that too incorrectly.
Considering three webpages. In all pages there are gridivews. The gridview columns has numeric data.
When user click on data figure suppose 29 then it redirects to other page with 29 records. In the redirected page if user again click on data suppose 12 then it redirects to another page with 12 records.
I want to give option to user that if form third page he wants to go back by clicking a hyperlink on that page then the second should appear in its previous state i.e. have showing the clicked value 29 and if he wants to go the first page then first page should keep and display its previous state with the searched data.
I have a gridview, getting data from sql server, there is an Edit link to get the detailed information for example, for a user from database.
this link open a new page with detailed information and when I click the updated button,I want to go back to the same page with that users informaton.
I set the page size to 10, it means I can see only 10 users per page,and if I click the edit link on page 25,and update the users info, I want to go back to page 25.
Should I use viewstate or gridview has any commnad to go back to the same page? the code is written in ASP.net C# sqlserver,
I am having problem while using onclick="javascript:history.back();" with Aspnet. In the first page i filled some data and click search button it show some results, i click on particular result for its details which navigate to the 2nd page but when i click on custom back button it refresh the page and all data set to initial values,when i use onclick="javascript:history.back();" I get nothing but the page displays "webpage has expired."
using System; // We need these namespaces imported to work easier with database using System.Data; using System.Data.SqlClient; // Here is PagedDataSource class located using System.Web.UI.WebControls;
