I have a gridview with two image buttons, I was wondering if anyone had an example of moving rows up and down. I've found a few online but they didn't really suit.
I am using RowCommand event as this is where I handle my Inserts, Deletes etc. So it would be ideal if I could handle it in this location as well.
The gridview is populated using a Lits<T>
I want something with works like this: [URL]
client side or server side, doesnt matter
I have 7 different category pages and although the Cart Page shows selected items From the 1 category , when i select other category page it only shows the selections of first page and not the others.

I have a following scenario - A use selects criterias from a webform (C#) - a result is then returned from the sql. Say, to start, there are 2000 data returned from the sql and are stored in a dataset.
Now, the user wants to choose a number of drops (up to 6) - with the number of drops selected, they can enter their own quantity in each box. So, they can divide the 2000 records into 6 different drops. With each drop, there is campaigncode created based on the mail date and the job number they provide.
So, now i have the 2000 records in a dataset. What i want to do is loop through the gridview where the user fill out the quantity depending on the number of drops (for ex: if they say 3 drops, then there will be 3 rows in gridview with 3 quantity box to fill).
In the loop, I am getting the quantity, dropdate and the job number. The Campaigncode is created as well. Then, i am looping through the datarow in the dataset; updating the Campaign Code column with the CampaignCode for the number of records thats set in a loop. It works but the Campaign Code is not populated for the next set of records.
Here is the code:
[Code]....
I think its this line right here thats causing the problem. But i don't know how to tweak this so as to accomplish what i want to do.
if (Convert.IsDBNull(DSAEFile.Tables[0].Rows[i]["Campaign Code"]))
I am trying to delete row(s) from the DataTable conditionally but I cant.
Actually I have DataList with CheckBox (default value checked=false). I am bindind DataList at run time using DataView (Dataview is created fromDataTable).
I also have <asp:Button ID="btnDelete" ....> which I am using to delete checked items in the DataList (But this functionality is not working).
The user first "checked" items in the DataList and click the the button "btnDelete". Here nothing is being deleted (?) and the DataList appears with all the items"unchecked" (even those which the the "checked" by the user). protected void btnDelete_Click(object sender, EventArgs e) . In this function I am checking state of the checkbox before deleting the row in the DataTable.
On PostBack generated by the "btnDelete", DataList appears with checkboxes unchecked therefore nothing is being deleted
Here is the DataList

Following is the .cs file

I am working with GridView/TelerikGrid control. It is having filter option. When I filter the data,
I need to copy only filtered rows into Datatable for further processing.
Suppose I am having total 10,000 records. and when I filter on column say Dept="IT", I get 1000 records in grid. So these 1000 records only should get copied into Datatable. So How to achieve this ?
Cwhat can be done over this ? I tried number of properties for grid. But there is no property which will return fileterd data source. Also I am not able to go every page of Datagrid and collect the data. I can get data for first page only. If I need to collect the data by going to every page of gridview, what is the way for this ?
In my continuing effort to build a search page that sends gridview rows with a textbox txtQty <> 0 to a listbox via a datatable, I've written the following:
[Code]....
The page runs, I'm able to input values into the textbox and when I press the Add to Quote button inside my gridview, nothing is populated inside my listbox. Am I correctly binding my datatable to my listobx?
So I've been teaching myself ASP.NET and VB for about 3 weeks now, having trouble with datatables, not sure how to get the rows to line up like I think they should. My code:
[Code]....
Which gives me the data output I want, but the days are adding rows underneath the previous day instead of lining up side-by-side. The idea is that once it's working I'll replace the specific dates with calendar controls. The gridview currently outputs like this:
I have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).
What is the best and fast way to do it?
I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?
I'm also looking for example in code how to select/delete rows from DataTable.

I have a ListView with Checkbox. My requirement is - When I click on any checkbox then it should return all the columns values of that row on behalf of that CheckBox. After much study I came to know that using DataTable and DataRow I can get all data of particular ID of a Row. But I am unable to work with this. My code is something like below:
DataTable dt=new DataTable();
dt=objBAL.Get_ShoppingCartData();
ListView1.DataSource=dt.Tables[0];

I know how to bind the columns to a grid and its no problem to create such a dropdown list with the content for me, too. But i dont know how to sort the complete datatabl after changing one value of one dropdown listbox.
So, how can i resort the values of a datatable column based on a given value and the datarow id?
I have a datatable,columns are(User_id,Name,Address,DOB)

(8,klm,banglore,17/5/2001)
(9,asd,pune,12/9/1999)
Now I want to sort these rows on DOB in descending order..how can i do so?
I have a DataTable of available time slots. I have another DataTable of reserved time slots. I need to remove from the list of available slots the ones that have been reserved. The blocks are in 15 minute increments, but one of my problems is that the reservation can be longer than 15 minutes. I've had some luck removing one or two, but not all of the required columns.
Here's my code (it doesn't work right now).

I get the usual system.outofmemoryexception with the code below.
Is there a way to do this in small chunks?
public static void Serialize(DataTable dt, string filename)
{
FileStream fs = new FileStream(filename, FileMode.Create);
BinaryFormatter bf = new BinaryFormatter();
try
{
bf.Serialize(fs, dt);
fs.Close();
}
catch (Exception)
{
fs.Close();
fs.Dispose();
File.Delete(filename);
}
}
If I am passed a datatable and I cant change the column structure..is there anyway to set an existing column to a Primary key so I can easily Find() the row I am looking for?
