I have an application as in the following,
[Code]....
The application works, but I would like to have 10 results per page. How easily can this be done? I don't want to use data view or grid view like most of the examples talk about, I would like to do this in the fashion that looks like what I have now, only not so many entries in a whole page.
I am having a datatable in which the data is as follows
No Name Text
1 a abc
1 a xyz
1 a asd
2 b aaa
2 b bbb
I want to querry this data table to get the result as
No Name res1 res2 res3
1 a abc xyz asd
2 b aaa bbb
i got a Gridview which is bound and draws its values from a DataTable.
My question is how can i sum the values of the p_price column and view the result on a label located on the same page?
I have this ListView that has a Drop Down List.Everything works fine (I think/hope) except that the drop down list are not showing its result correctly.This is the code.

Using a GridView to display unique website department names from a database table, is it possible to create a hyperlink in the GridView to that specific departments page? I'm a beginner and haven't found any examples so unsure as to how this would be accomplished.
View 8 Repliesam using vs 2005 and sqlserver 2005.in my database table (name : users) there are more than 10 lac records.i have to display the user details in a grid.if i wrote the sql query as " select * from users" then it is throwing the "System.OutOfMemoryException"So i wrote the query using rownumber (i mean first it will get inly specified no of records ex:25 )so it is displaying only that 25 recordshow to give paging in this situation...?y requirement is in the grid i want to get and display first 25 records with the paging asirst Previous 1 2 3 4 5 6 7 8 9 10 Next Last
View 5 RepliesI 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?

My question is: how can i create my own parameter based upon the QueryStringParameter?
Example:
[Code]....
I now called it QueryStringGuidParameter.
The purpose of this is: I'm not sending any querystring's via the aspx?querystring other thasn aspx?guid={guid identifier}.I hope my code below explains it al little bit.
[Code]....
A soon as a page Redirects f.i. with this example
[Code]....
Instead of calling Response.Redirect i call the Redirect i created. This transforms the querystring in a session with a guid and parameter. The Redirect only sends the guid in the querystring. and the receiving page picks up the guid and translates it back into a querystring.
Purpose is you have a secure way of dealing with info sending via querystrings. Lets say in the past you could easily get other info from the page by just changing a value in the key send via a querystring. In my case lets say the user request a Customer "A" with querystring ?ID=1.
Simple change the query in the addressbar to ?ID=2 (or something else) would give him another customer. Maybe a customer he is not allowed to see. (Of course this can be prevented also in the business layer, but that's not the point.)
So if i simply could create a new QueryStringParameter lets say called QueryStringGuidParameter which i can use in the ObjectDataSource but ideally just for all controllers which are able to use the QueryStringParameter , i don't have to go into code behind and set the SelectParameters in there.
I'm trying display data from a sqldatasource but I need to customize fonts, sizes and layouts. What would be the best way to do this. There's not much data only 8 rows and 3 cloums.
It's for a display screen that will show workers how much product they have produced.
I was looking at binding the data to lables and laying out the lables in a table but that process looks intense and streching my knowledge.
I have a asp.net gridview control on my page with several fields and a couple of command fields. However, the update command is giving me problems.
Here is what works. The update command works provided I put straight text into the textboxes that appear. I even have one field that contains a dropdown list which works fine.
Here's the problem. I have two fields that need to access their value programmatically. These fields will reflect the current datetime and the current loggedin user from active directory. I have already created public strings in the C# code.
When I run the edit command on the asp form the grid uses one "DataKeyNames" element. With this the grid can update the selectedrow. However, I haven't been able to access it programmatically in the C# code. I can access the selectedrow in the "selectedindexchanged" event but then I am not able to update my fields in the gridview itself. So, part one of my question is how to I access the "DataKeyNames" properties of a gridview control.
if I can't access the "DataKeyName" property perhaps I could set the label nested within the gridview to the "myCurrentUser()" public string. I am inserting my code to hopefully make this clearer.
I'm gonna outline the application roughly: it's a tool, where people can upload a CSV-file, which contains their data for some crazy water-plant-biology-stuff. ;) The job of the application is (besides others) to validate their entered species. So far no problem, I've got my string-array with the correct species abbrevations, and i can parse the species names from the user-edited CSV-file.Whenever a species is found, that is not part of the reference-array its being sent to a GridView as a new row. All of the above works fine - if anything isn't explained well, just ask.
Now, what I want to do is to give the user a simple edit-function: beside the WRONG species name, it would be terrific, if there was some sort of drop-down-list, filled with the correct species names (which are stored as a string-array in my .cs-file!). The user looks at his wrong species, then just has to select the correct name from the drop-down-list, either updates row for row, or even better: edit every row, and update once at the end. Is this possible? I remember that it's quite easy to fill template-fields with data through SQL-connections etc, but is there a more simple way to do it? As said, I've got a fine string-array in my .cs-file behind the aspx-page.Haven't found any code for this. Are template-fields in the Gridview the right way?
Which might be a solution for the updating-problem: I keep storing the wrong names in the rows, and just add another column next to the species name, where this drop-down-list should appear. Then i add a button, which, when clicked, gets the old value & the new selected value for each row, and updates the data. Should work? So the problem remains: how do I add a template-field with many (<500) items in the .cs-file to a GridView-Column?
I have two tables: Projects and ProjectsData and I want to execute query with join and get the result in the View. In the Controller I have this code:
ViewBag.projectsData = (from pd in db.ProjectsData
join p in db.Projects on pd.ProjectId equals p.ID
where pd.UserName == this.HttpContext.User.Identity.Name
orderby p.Name, p.ProjectNo
select new { ProjectData = pd, Project = p });
What I should use in the View to extract this data. I tried that:
@foreach (var item in ViewBag.projectsData)
{
@item.pd.UserName
}
but it doesn't work.
when i found datareader object containing data after execution of query
simply giving gridviewdata=dr;
does not work
I want to get data from Projects(which have CourseId) and related CourseName from Courses table.
I have written following code:
var projects = from n in db.Projects
join c in db.Courses on n.CourseId equals c.ID
orderby n.Name
select new { Project = n, Course = c };
return View(projects.ToList());
and I get error:
The model item passed into the dictionary is of type 'System.Collections.Generic.List1[<>f__AnonymousType22[ProjectManager.Models.Project,ProjectManager.Models.Course]]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[ProjectManager.Models.Project]'.
What I need to do in Controller and in View to display this data?

DataList1.DataSource = GetAllNameDoc(ids);
DataList1.DataBind();
but it is not work.

I have a complicated report that nests six deep and so really hits the database hard. I want to use SqlDataReaders NOT DataAdapters and DataSets because I don't want big tables in memory.
MARS can get me the data fast, all from the one connection. But all the examples show it binding to a treeview.
I want to bind it to nested GridViews (six deep!).
Any examples of MARS binding to nested gridview/list/repeater controls of any kind?
I having problem binding web service result into a gridview. I using Word Dictionary Web Service for my project. Below is part of my code.
Web References I using is :
[URL]
Protected void Button1_Click(object sender,
EventArgs e) {
DictService ds = new DictService();
ds.DefineAsync(TextBox1.Text);
ds.DefineCompleted += new DefineCompletedEventHandler(ds_DefineCompleted); }
void ds_DefineCompleted(object sender, DefineCompletedEventArgs e){
GridView1.DataSource = e.Result;
GridView1.DataBind();}
The Error i get is : Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource.
If i have a page which displays all the data but with only a few fields, then i select one of the data and then i want to be able to view that data with all the fields related to that data on another web page.

I have an aspx webpage with a databound DropDownList and a databound GridView control. The GridView datasource is using a WHERE clause to return its' data. I.e. The user selects a work area from the DropDownList and members of that area appear in the Gridview. The GridView has 3 columns, WrkArea, LastName and FirstName. The page also has a Button.
What I am trying to accomplish is when the user clicks the Button, the data from the GridView is copied to a separate SQL table. I am working in VB. I have been looking at other posts but have to admit, I am really confused.
