i could bind the data form tables to dropdownlist in asp .net using linq.
ex: var res=from n in dc. contacts where n.location==Hyd select new{n.Id,n.Name}; var res1=from n in dc. Morecontacts where n.location==Hyd select new{n.Id,n.Name}; dropdown1.Datasouce=res; dropdown1.DataTextField="Name"; dropdown1.DataValueField="Id";
now in above, if i want only those hotelid where amenityid is 7585 and amenityid is 65474 and not any else hotelid , then how to use select query in datatable in asp.net
I have two tables namely "CategoryMapping" and "PartnerCategory"...The partnercategory table has foreign key with categorymapping on CategoryID...
let us say categorymapping should be filed first then partnercategory should be filed based on the categories defined in categorymapping. For example my two tables have the following data:
I came across a situation where a user selects no of rows from dropdown , depending upon the user input, automatically that no of editable rows should appear to input data...(maximum 8 rows only)

i'm using the code below to select multiple rows in a gridview using a checkbox, how do I modify the code in a "select all" button click event to select all the rows by checking the checkboxes in all the rows? How do I also clear all the checkboxes using sa "Clear" button click event?

Im coding in VB Im looking to transfer data from a gridview to a table. In the grid view i have enabled Selection, and on the code behind, as i need help getting started selecting the attributes adding it to a table. The grid is being populated from a table however i would like to take the information selected and store it in another table, which will have some more attributes. i have found a way which will add the row by an sql query from one table to another however i would like to give the user the option to select and add data to the table.
And i was thinking i could use this SQL query in the code behind but im not sure how to add it to the code behind of the select.
I have a GridView with an extra checkbox column to select rows.
To select multiple rows, the user now has to click each separate checkbox, but I would like to offer the possibility to select multiple rows at once using Shift+click.
Thus the user would explicitly select the first row with a single click and the select the last row using Shift+click. And the checkboxes of the rows in between would then automatically be checked as well.
I have a standard .NET GridView. How I can: 1. Highlight the row on mosue over (or hover),2. Activate the Select Event when you click on anywhere on the row?
I have a table with number a fields that repeat them selves ... then on submit saves to sessions to be used later on.I was to use a + and - button to enable and show more or less fields. So far i have an asp:table with a number of rows which are disabled and not visible.
When a user clicks +, i want it to disable the next hidden row. The easiest way i thought of doing this is with a select statement but i can't get it to work.This is what i have:
[Code]....
No matter how many times i click the button all i get is 1 as the value for noCreationRows.
I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.
And I am binding these repeater control with some datasource.
My requirement is to have focus on first item row and i should be able to use tab ket to navigate between various rows of the repeater control(which is ultimately a table)
There is no anchor(<a>) control inside the table.
I am using onclick event on table row which does something in my application.
I want my user to use TAB key to navigate between rows.
im tryin to do something without success. I have some SQL table with few columns (fileId(int), fileName, copies, color and finish), the page is build in a way, that the user upload few files (the files uploads to some folder, and the fileId and fileName are write to the above SQL table - so the other columns (copies, color, finish) are stay blank - which is OK!!!) after he finished uploading the files he can see the files names in GridView and in that grid view i put some textbox for copies, and 2 DDL for color and comments. I need to update the rows with the new data after the user click some button (the all rows) this is the code:
I am trying to follow an example from Lesson #25 of [URL] I am not trying to do paging as the above example is doing. I simply want to do a Query and return the the number of rows back in my code behind.
I have a DAL Typed Dataset with the following Query
SELECT COUNT(*) AS Expr1 FROM Reservation WHERE (DateUsed = @DateUsed) AND (SiteID = @SiteID)
I have one table named 'dbo.ac_Products' Within this table there is a column named 'ProductId' There is also another table named 'dbo.ac_CatalogNodes' Within this table there is a column named 'CatalogNodeId' and a column named 'CatalogNodeType'
I need to delete all the rows from 'dbo.ac_Products' and 'dbo.ac_CatalogNodes' where 'ProductId' = 'CatalogNodeId' and 'CatalogNodeType' = 1
