MenuItem menus = new MenuItem();
GridView1.DataSource = menus.GetDataTable();
GridView1.DataBind();
menus.GetDataTable() returns a DataTable. In the above case, we are returning to GridView. I need to populate the data into a combo box. How can i do it?
NOTE: Assume GetDataTable only returns records of a single column. I'm using Winforms

I have a requirement that I need to read an excel sheet using asp.net/C# and insert all the records into mysql table.The excel sheet consists of around 2000 rows and 50 columns. Currently,upon reading the excel records ,I am inserting the records one by one using a prepare statement into mysql table.But its taking around 70 secs to do so because of the huge data.
I've also thought of creating a new datarow, assigning values to each cell,adding the resulting datarow to datatable and finally calling dataadapter.update(...).But it seems to be complex because I got around 50 columns and hence I'll have to assign 50 values to the datarow.
I am binding same data Table to Combo box and List Box on the WindowsForm Load.
When I select a value in Combo box automatically that value is also getting selected in List Box and same thing when I select a value in List Box that value is also getting selected in Combo Box.
Selection should be only for that particular control, how can I achieve this ?
i have 2 combobox A & B.. the values in B is populated according to selected value in A,, my code works fine when i click combo A and select a item,, the values according to it get populated on combo B. i have written it on the change event...
But when i use tab to navigate and select the items in combo A and change on pressing keyboard down key...the items in combo B is not getting populated with new values.. existing values does not get changed,,, ie change event is not getting fired... how can i manage it in down/up key in keyboard when using tab,,,,

I want to populate a gridview with table data from SQL. I tried just returning my SqlDataReader object and using it as my datasource, but I am getting errors that the reader has been closed. I wanted to convert this to a DataSet and just return a dataset, but I couldn't find an easy way to convert the row data to a dataset. I've also read that DataSets are dead in .NET 3.5/4.0, is this true? Here's my Data Layer method. It would be awesome if I could return something useable as a datasource:
public SqlDataReader GetSites()
{
SqlConnection sqlCon = null;

I have two tables, Users and Roles. The roles table is a reference table for the different roles of my site (RoleId and RoleName columns). The Users table contains profile data for each user, including a RoleId column that is FK'd back to the Roles table [RoleId].
Both tables are in a Linq to SQL model.
I have an edit page created which lists all the profile values of a user. The edit page inherits the User model. One of the editable values is the RoleId field. I want to set this up to be a drop-down list that contains items labeled using the RoleName column of the Roles table, and matched with values of RoleId.

Basically I want to populate a drop down list with time slots for a user to select. If the time slot is already recorded in the database table I want to skip that one so it doesn't display as a selection in the drop down list.

View 2 RepliesI have textboxes of customer Address data. bound to Invoice table. Displayed on a Page.
I want to be able to show same data in detailsview. bound to Delivery table
using the following criteria:
1. check delivery table for address data, where email = usermembership Email address and populate Detailview. If no data present, copy Customer Invoice Address data across IF present, to Delivery Detailsview.
2. Insert record IF no Address found/Update IF record amended in Delivery detailsview(Only applicable to Delivery Detailsview)
I would prefare this to be accomplished in a Button_Click event instead of using Command buttons in bottom row of Detailsview.
This is because i am using a Multiview page that processes Customer Address data.

What am i doing wrong?
I want to know how we can create a table (or a layout consisting of div's) and poulate it with data from the database. We do this generally using data controls like gridview, datalist etc. But i am restricted by these controls like there is no inbuilt paging with datalist and there is no repeat column in gridview. I just want complete control over the layout as well as the data that goes into it.
I dont know how to do this. Is there anyway of doing it without using the data controls.
i need to display whole table including headers with repeater ,,

Add rows dynamically to a table and poulate data in cascading dropdowns,I am using ASP.NET3.5,
View 2 RepliesI'm currently switching over to ASP.NET MVC and have ran into a problem. I have a list of items (e.g. a list of names) that I would like to display in a table. I would like to display it down a column, before starting onto next column.
I have tried a nested for loops for mark up of <tr/> and <td/>, and am getting undesired results.
I have 3 tables(Roles,Actions and RoleActionLinks). Roles table has few columns(RoleID,RoleName,Desc). Actions table has few colums(ActionID,ActionName,Desc). In RoleActionLink is created for store the association between Roles and Actions and this table has the columns such as RoleID,ActionID When I created the data model(edmx). it shows only Role and Action as entity. i did not find RoleActionLink table. but even there is no direct relation between Roles and Actions table, both tables are automatically related using RoleActionLink table. When i create the new Action, a action record should be populated in Action table(this is works fine). At the same time, i need to populate record in RoleActionLinks table. But i dont have the entity to populate.
View 1 Replies new developer here. I'm trying to populate a ASP table dynamically. This is what I'm trying to do.I have table with 1 row and 4 cells. I want to import information from a text file into the various cells. Each line of the text file is what I want to go into each cell.
For example if the text file reads:
Date
Time
Path
User
I want each line to go into each cell. Is this possible, or will I need to create a SQL Server table and read from that?
