View 1 RepliesI want to copy rows from one datatable to another.
View 1 RepliesI 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 ?
i have the dataset with one table.Table contains three column like 'Name','Location','Pin'.I would like to move the data from another table based on schema.

View 2 RepliesI 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 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).

have a page that has a results gridview where I have all rows with a chekbox. when I click on the checkbox I try to create an excel filethis is method content:
DataTable MyData = new DataTable();
//recorrido sobre los elementos seleccionados6
foreach (GridViewRow row in gvwDbf.Rows)
[code]...
The problem is that excel file is totally empty. When I trace on the error I find that (item on bold above) dt datable has current record as I expected but Mydata table has nothing inside. shouldn't I use import statement? How can I get the row copied? I intend to have a full table made by every record coming from parameters of each query which is performed inside a for each sentence
i have searched quite a bit on this one and can't seem to find exactly what I am looking for.
I think my first problem is this: How would I bring back a DataTable FOR copying? I know I would need:
Dim dt as Datatable
But then how do I get the Original Datatable in there? I think that once I have that part, I can just make a connection to my new DB inside a copy subroutine (using the .Copy method) and be done with it. That part I have the code pretty much done for, I think.

I have a gridview with empty data template. In this empty data template i have a table(HTML) with 4 columns. When user enters data i want to save this in a datatable temporarily at a button click event.. Again if user wants to add one more rows data that also should be added to the same table where i added previous row data. So now the datatable has 2 rows. Like this he may add any no of rows. What i want is all the rows should be displayed when i bind datatable to gridview..At the click event i am adding 1 row at a time to the datatable
View 1 RepliesI 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

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:

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:
