I have a GridView which populates
ID Name City
1 Bobby AAA
2 Laura BBB
3 Ilisha CCC
I want to get an enumerable collection something like following
var Query= from p in GridView1.Rows
select new { User_ID=p.ID,User_Name=p.Name,User_City=p.City }.ToList();
I would like to write Set difference minus operation with Linq on list objects using Except method. [Code]....
Tha above code always returns lstrbb objects.
in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.
View 1 RepliesI have a simple add form on the page and below it is its gridview with edit and delete buttons. Everything works fine, but when i click on edit on a particular row/record, it changes to edit row but i want the record to be edited in the original add form (which is above the gridview).
I am able to edit a record on the gridview but i want it to be edited in the add form. Is there any particular way to do this? I came across formview concept but not sure if i am able to do that with it.
Below is the form and gridview code.

I would like to know how to avoid the same operation from being performed twice after some action has been taken on the gridview.
i.e. on clicking a button in gridview, operations in RowCommand get executed. Then on doing a page refresh, the same thing gets done again.
How can we avoid this?
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" ForeColor="#990000"
AutoGenerateEditButton="True" onrowupdated="GridView1_RowUpdated"
[Code]....
these are my avaiable controls on the page
now on clicking the update button
i want all the values to be displayed on textboxes as above mentioned
Request to updated me with the syntax for update gridview rows in asp.net 2005.
View 4 RepliesI am inserting mortgage loan scenarios in via GridView table. Let's say $100K loan with FICO score 700 in state of MN.
Sometimes I want to apply the same scenario to multiple states rather than Inserting one row at a time. I figured a Listbox with SelectionMode="Multiple" option would be to way to go.
Here is some code snippets:

I want to do one thing that when i edit the gridview then it will not go back to main form for editing.it will remain there in the form for the row editable.

I have two textBox, one button and one gridview. In one texbox, I enter a value, click the button to add this entry to the gridview and the footer is computing the sum as i add more entries to the gridview.
I also have a textbox outside the gridview that will hold an amount, now I want to perform an operation like...(txtOutsideGridview - gridviewEntry1 - gridviewEntry2), and display the result of this operation inside the footer of the gridview, instead of the sum. How do I go about doing this?
So far all I have been able to do is sum up the total of entries within the Gridview, but that is not my desired operation...here is what my current code looks like

View 4 RepliesWhen one has a Gridview and two datatables and one wishes to get the parent row and bind it to a gridview, how would this be done?
View 1 RepliesI have a datakey that I'd like to query from my GridView instead of looping through all the rows and comparing the key of each row. So I was wondering if it was possible to just do a linq query on the gridview (not datatable) and filter with the datakey.

i m binding data to Gridview using LinQ i need to sort the Gridview i have no idea how to sort cs i m using LinQ to Bind data with Gridview at Button Click.
View 2 RepliesI have a grid bound to a linqed SP thus:
Session["results"] = db.spGetCaseByNumberOrSurname(txtCaseNum.Text.Trim(), null).ToList();
gvResults.DataSource = Session["results"];
on the sorting of it, i would like to be able to do this..
protected void gvResults_Sorting(object sender, GridViewSortEventArgs e)
{
string sortExpression = e.SortExpression;
List<spGetCaseByNumberOrSurnameResult> data = Session["results"] as List<spGetCaseByNumberOrSurnameResult>;
if (sd == SortDirection.Ascending)
{
sd = SortDirection.Descending;
gvResults.DataSource = data.OrderBy(d => d.GetType().GetProperty(sortExpression));
}
else
{
sd = SortDirection.Ascending;
gvResults.DataSource = data.OrderByDescending(d => d.GetType().GetProperty(sortExpression));
}
gvResults.DataBind();
}
sadly that doesnt do any sorting at all..it in fact errors with "The data source does not support server-side data paging."
My project includes a grid view which displays information of inventory items (Assets), data is quried from AssetTable. The GridView has a command field to allow editing, below is a description of the tables and how data is displayed
Tables
BuildingTable: (BuildingID, BuildingName)
AssetTable: (BuildingID,..,....,....)
ItemTemplate: Using a LINQ query I join the two table and displays in a label control a string which includes BuildingID and BuildingName (5 North Building)

When I populate a gridview with a linq to sql datasource, I get the results I expect, however, when I try to use a linqToSQL query and try to databind that to the gridview, I get no records returns.
My Linq looks fine and I don't recieve any errors, so if someone could take a quick look and point out an obvious flaw.
[Code]....
i have two tables tblProduct and tblCategory, what i am trying to do is populate a gridview, i have LinqDataSource binded to the grid and the correct association made inside the .dbml (tblProduct.CategoryID to tblCategory.ID).
To show the fields from tblCategory instead of the tblProduct.CategoryID in the GridView i am using :
<ItemTemplate>
<asp:Label ID="Label5" runat="server" Text='<%# Eval("tblCategory.Name") %>'>
</asp:Label>
</ItemTemplate>
This works fine inside the VS2008 debugger, but once its published to the server (2003 + IIS6.0) the column that belong to tblCategory simply don't show, instead of having the category name (tblCategory.Name) displayed like it does inside the debugger it is blank, no errors simply wont show.
Loading data into gridview, retieving data using linq,I have a method that accepts two paramters that would sort specific field and return the object to the gridviewi.e.
passing into the method GenerateData(string sortExp, string sortDir)
sortExp = "Name", sortDir = "descending"
linq query://works

How to copy the displayed data from grid view with LINQ?
Example:
In the GridView I have a data:
ID, Surname
1, Surname1
2, Surname2
3, Surname3
How to copy this information in the same GridView and to add new IDs.
Finally, the copy must look like this:
ID, Surname
4, Surname1
5, Surname2
6, Surname3
I have a GridView which needs to get updated on RowUpdating Event. How can I update data using LINQ?
I am populating GV using LINQ too and here is the code for that:
protected void Page_Load(object sender, EventArgs e)
{
string getEntity = Request.QueryString["EntityID"];
int getIntEntity = Int16.Parse(getEntity);
using (OISLinq2SqlVs1DataContext dt = new OISLinq2SqlVs1DataContext())
[Code]....
I have a gridview with several columns, 3 of which I'd like to sort. The source for the data is held in the session.
protected void MyGridHistorySort(object sender, GridViewSortEventArgs e)
{
var TheColumn = (e.SortExpression).ToString();
TheDataHistory = (List<ViewDataHistoryModel>)Session["SessionDataHistory"];
var test = "data.DataDate";
var NewDataSource = from data in TheDataHistory
orderby test
select data;
MyGridHistory.DataSource = NewDataSource;
MyGridHistory.DataBind();
DataDate is a valid column in the list but the orderby statement doesn't work. Ideally, I'd like it to sort with the variable TheColumn by writing something like test = "data."+TheColum; and then add a sort direction based on a boolean. I looked at the OrderBy extension method NewDataSource.OrderBy(test); but that doesn't work either.
I have a GridView which is not bound to any DataSource. In my page load event I am writing this code:
protected void Page_Load(object sender, EventArgs e)
{
string getEntity = Request.QueryString["EntityID"];
int getIntEntity = Int16.Parse(getEntity);
[Code]....
Now I can see the the value is coming from previous page, but my GridView is not populating anything. What I am doing wrong here?
