I haven't worked on the UI in some time. I thought that in ASP.NET 4.0, gridviews handle the paging automatically (if you set paging=true). Is this true, or do you still have to handle it in code?
View 2 RepliesI haven't actually dealt with multiple grids on one page in a very long time, so perhaps someone can jog my memory. I have two grids and a treeview in three separate jQuery UI tabs. Every time I page my gridview, which is a custom control inheriting from Gridview, the other tabs refresh.
View 2 Repliesi need to show 3 gridviews in a tab container (ajax).. which should refresh at same time.. what is the optimal way to get data from database for that can some one show a solution for this .
i need to design an application in asp.net using gridview custom control. the gridview will show hundreds of records using paging with checkboxes in every row. if the user checks 3 rows in first page of gridview which is showing 9 rows, those 3 rows should appear on top in the next gridview page and the page should display only 6 new records. ie 6+3=9 similarly if user checks 2 more rows, the next page should show 3+2 rows(from first 2 pages) on top and only 4 new rows ( 3+2+4=9)software developer
before I started working with LinQ I used Objectdatasources to bind a GridView.
To get a label like "item 20 - 30 from 54 items" I used a dataview like this:
Dim dv
As Data.DataView = ObjectDataSource.Select()
Dim count
As
Integer = dv.Count()
Dim first
As
Integer = 1 + (Grid_View.PageSize * Grid_View.PageIndex)
Dim last
As
Integer = first + Grid_View.PageSize - 1
If last > count
Then
last = count
End
If
How can I do this if I bind my GridView with a LinqDataSource?
if Entity Framework 4.0 handles simple transactions automatically?
If I am only making changes to the ObjectContext, and use ObjectContext.SaveChanges(), does EF 4.0 take care of the transaction behind the scenes?
In other words, if I perform a few inserts, updates, and deletes on several different Entities and one of the fails, is everything rolled back?

What's a good way to handle "paging" in a web app? I want the user to see only rows 1-20 from a data query, but they can then choose to view rows 21-40, then 41-60, etc.
More detail:
I'm building an app that will return a bunch of news articles from a database.
I will be converting the query results into XML and transferring it via web service. I will then convert the xml into an HTML table to show in the browser.
The query will return hundreds, but I assume it must be more efficient use of bandwidth and server resources to show only 20 at a time.

View 3 RepliesI'd like to implement a custom paging template for my formview that displays numeric paging as well as next/previous buttons. The pre-defined templates only appear to have numeric first last as an option. Can anyone recommend a good article that covers this?
View 2 RepliesI am passing the PageNumber and PageSize to a stored procedure, which returns only that page of data. It also returns a record count what the total number of records would be if I returned all of them at once.Generally, how do i hook this up to the DataGridView to enable paging?It seems like the expectation is for the resultset to contain the complete dataset. Many of the properties that I expect to be able to set, like RecordCount, appear to be read only.
View 2 Repliesi have dataset ds with 4 coloums. the 4rth colom has values either '1' or '2'. i want to split this ds into 2 datasets ds1 and ds2 depending upon whether 4rth colom is '1' or '2' .
then i want to bind gridview1 to ds2 and gridview2 to ds22.
Is there a way to define a <Columns> outside of a GridView in my .aspx file such that I can use those <Columns> in multiple GridViews in the same page? I have two GridViews that will have the same DataSource type, just with different content, and I'd rather not repeat all my customized TemplateFields in each. This seems simple enough, it's just I'm new to ASP.NET. Coming from WPF, it feels like I should be able to define my <Columns> in some parent "Resources" area, define its TargetType, give it a key, and then reference that key wherever I want those <Columns> to appear.

How can I get several GridViews on a single page to share the same Column widths?
I have four GridViews with (essentially) the same columns in each. They have unique headers and represent data from different queries. I want to maximize readability by allowing the columns to be dynamically sized based on the data but I don't want each GridView to do it independently. Having same-named columns one above the other with different widths looks very sloppy. Instead want all four GridViews to choose the same size for column 1, the same size for column 2, etc.
In windows apps I believe there is a property for this called SharedSizeGroup which allows you to set columns from different controls to collaborate when deciding on the optimum size.
Can this be achieved at all in ASP.NET? Is it just too much to ask because the dynamic column widths are up to the browser?
I am trying to have the page fully load up and then after that load my gridviews as they take some time to generate..
Right now I do it with a timer and an update panel with the timer being set to 1 second which works perfectly fine but..
I don't want the page to be using the update panel when they click any button on it etc., I want it to function as a regular page. What is the solution to this?
If i want to use this layout for multiple pages, what is the best way to do it so later on if I decide to change something in the layout I wouldn't have to go through all of these pages just to change 1 item.
I have multiple gridviews to be exported to excel. 1 gridview per worksheet.
How to do that ? ( or in general how to write an html string to a worksheet )
This is to be done in asp.net , server side.
I can create multiple worksheets via epplus.codeplex.com nicely, but it works on cell level. I could export DataTable, but how to export Gridview's HTML ?
I want to have multiple gridviews in a panel. and the number of gridviews is not fixed..
So basically i think there should be no code in the .aspx page as i have to create the gridview in codebehind.
I have the code for 1 gridview in one panel.. where i define the grid view in the HTML page and populate it from the code behind.
Here is the code for that..
this is on the .aspx page
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
AllowSorting="True" CellSpacing="2" onsorting="GridView1_Sorting"
Width="100%" ForeColor="White" GridLines="None"
ondatabound="GridView1_DataBound1">
<Columns>.......

I have an application where I currently are calling stored procedures, reading tables and filling GridView at PageLoad (If Not IsPostBack Then ...). The process takes some time and leaves the client waiting for this process to be completed even before showing the page.Now, is there a way where I can open the page, show a hour glass (or similar) and then automatically fill the gridviews? Is this where I should use threading (or backgroundworker) ?
View 11 RepliesI have this "how to" type of question. I have a page where there are four gridviews. Now these four grids pull data from four different tables. The 1st grid retrieves data from table 1 with a where clause in it's query that comes from a hidden fileld value in the page. Till this things are fine. However, the 2nd grid has a dependency on the 1st grid and the where clause in it's query should be the data selected in grid view1. The 3rd depends on the 2nd one..and so on.
