Forms Data Controls :: How To Get A GridViews Paging Text Like "item 20 - 30 From 54 Items" With A LinqDataSource
Mar 25, 2010
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?
how to move items between two gridviews. my requirement is as such that the items can be moved around and once the user clicks on the save button then only will the final items in the gridviews get committed to the database.
i 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
Im making a Master details web page ASP.NET. I have one aspx page with all the items in a listview, then a link to another page to show the details view, but I dont want to use a asp:detailsview control becasue it generates a table, and I want a more complex layout. I want work each property of the item, but I dont know how. I want to do in LINQ. This is my very bad aprox: I need an orientation of how to get ONLY one item from the LinqDataSource on the page load and not to query the database everytime I need a column. I dont need biding because I only need to show data, not insert, not update, not delete...
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?
Here is a button inside a listview that is using the LinqDataSource and also has a pager:
[Code]....
And here is the Code Behind that is triggered by the linkbutton:
[Code]....
It almost works. When i click it it loads and shows the current page of objects that have dates that are higher then todays date. Which is what i want. But as soon as you use the pager to go back or forward it reverts to the default, which is ALL articles, sorted by ID. How can i make the "where" selection stick through the paging?
i know how do the paging with normal return query using row number in sql server, but i'm looking how to do the paging , sql server full text search returning result.
Can i use the same row number function or any good perfomance way?
whcih sql server full text search(FREETEXT,CONTAINS and etc) is best article site?
I 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.
I have seen several Web Sites that use GridViews that have lookup fields with different Value and Text Fields (as in drop down lists) but I can't seem to figure it out how to display the Text Field in the Item Template when the Text Field is not in the datasource. .
Here's what I have. I have a Gridview whose datasource is a Linq to SQL Invoice table, e.g.
InvoiceID CustomerID InvoiceNumber
THe Customer table is related to the Invoice Table thru the CustomerID. The relationship is defined in SQL Server and is displayed in the DBML.
I have created a template field for the CustomerID field in the Gridview. I would like to display the CustomerName when the Item Template is displayed and a DropDownList in the Edit Template. The DropDownList works great, but I cannot seem to figure out how to display the CustomerName in then Item Template.
I seem to remember seeing in some video that you can simply drag the CustomerName into the CustomerID Item Template Field. But I can't seem to find the customerName field. The DataSource includes the Customer Table because of the relationship, but no fields are displayed.
I suspect this is real simple, but I cannot seem to find an article or video that explains how to do this.
I have a link button in my gridview. It is populating correctly; however, being I am populating the values in the gridview using "Eval()" method I don't know how to get the value of the selected Link Button (which is only selected by a user actually clicking the Link Button).
The user can click on the text directly (instead of showing the "Select" auto created). I want to be able to capture the item they have clicked on's Text property.
Example:Column 1
Value1 Value2 Value3
When the click on "Value2" I want the text property to be stored in a string variable (In this case the text would be "Value2"). In the past I have captured this through GridView.SelectedValue; however, I am not using autopopulate selected button so I need to do this manually and I am unsure as to how I will do this.
Here is my code for HTML and I have not created any code for C# (I want to capture the item using C# in my Grd_Tables_SelectedIndexChanged Event) [code]....
Is there a way to use the GridView paging and having the links not use JavaScript. So that when you click on the page number 5 (for example) that link is a hyperlink.
I'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?
I am having troubles making the code run. I have a web page with a gridview and a checkbox. I would like the button when selected to pass the category id. I have managed to get it work without paging. Once the paging kicks in see below, I am unable to run the code. see below.
I am dynamically bind the textbox in the data grid and in the text box change event i need to add the numbers in all the text box and show in the separate label.
I am using the text box change event and post back to true, I can able to calculate the result but the problem is that on text change itself i need to calculate and show the result, but in my case, when i move the focus from the that text box, the results calculated and focus get lost.

I have written the below pages (base of question) to populate my asp.net listview control from an objectdatasource. To allow for easier CRUD commands and to make my application more efficient I want to replace this objectdatasource with a linqdatasource but when I attempt this I receive a binding error which stops my ItemDataBound event firing? I'm basically replacing my objectdatasource with the below linqdatasource...
[Code]....
[Code]....
Am I placing my query within the wrong event? Why does my ItemDataBound event not fire?
