HOW TO specify which columns are in a DataView from a DataTable. I want to create a DataView, that only has the columns from a DataTable that I choose, and in the order I want.
Example:
// DataTable_MyTable ~~ Column #0 is for ID. I do not want my view to get this column.
// DataTable_MyTable ~~ Column #1 is for TYPE. I want this column to come in 2nd place in my view.
// DataTable_MyTable ~~ Column #2 is for NAME. I want this column to com in 1st place in my view.
DataView DataView_MyView = new DataView(DataTable_MyTable ~~ some how only get the columns I want, and in the order I want ~~);
// DataView_MyView now has only 2 columns.
// DataView_MyView ~~ Column #0 is NAME.
// DataView_MyView ~~ Column #1 is TYPE.
I am doing GridView Sorting without ObjectDataSource. For this requirement I need to convert DataTable to DataView, I know I can do that in VS 2008 but How can I do this in VS 2005.
View 20 RepliesI have one gridview and i want to take all the values in a datatable or dataview.
I tried like this
DataTable gridTable = (DataTable) dataGrid1.DataSource;
but gridTable is showing null, it should not show null because gridview has lot of records with 3 columns
Is there any way i can convert/store a gridview.Datasource records in a datatable or dataview?
When i try to sort my table manually, i receive this error:DataTable must be set prior to using DataView.The code is:
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)

How to select top n rows from a datatable/dataview in asp.net.currently I am using the following code by passing the table and number of rows to get the records but is there a better way.
public DataTable SelectTopDataRow(DataTable dt, int count)
{
DataTable dtn = dt.Clone();
for (int i = 0; i < count; i++)
{
dtn.ImportRow(dt.Rows[i]);
}
return dtn;

How could I parse a Json string with all the data from my table to a DataTable or a DataView?
View 5 RepliesI am trying to do something I thought would be simple but something isn't working for me.
I have a DataTable that I need to sort by a price ascending, then select an 'nth' row value. The 'nth' value is the row count/10.
[Code]....
What happens is I get the "nth" value from the original tblDeals.
I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview.
I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows).
If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that. Example Filename: DailySalesReport-1-15-2010. My only hangup with this is how do I sort on date, when it's a string value? Convert to date? How would I sort the whole dataset based on this converted value?
[Code]....
I want to get all the data of Dataview in a datatable (which also include the sorted feild)
I have a code
DataTable dt = new DataTable();
DataView dv = (DataView)ViewState["dv"];
dv.Sort = sortExpression + direction;
gvCustomers.DataSource = dv;
gvCustomers.DataBind();
I want to put this data view object to a table as it is. means if the coloum is sorted , then the sorted data should comes to datable or dataset
I have developed a website in asp.net 2.0 with backend MS SQL server 2005. After each 2-3 days when i try to login to my admin panel i get a /server application error "datatable must be set prior to using dataview ".When I made a research on this i found the error is in the caching part of the code where i am using a dataset to fill my dropdown lists. But I am using the same code everywhere and on other place i didn't get any error but on a specific page. i usually get error when i try to login to admin. After successful login i redirect the admin to a page adminBazaar.aspx. and the error is always thrown by dis page only.other pages with the same code are working fine and there are no issues.I am using SqlCachingDependency. but can't figure out how to solve the problem.Right now to solve this I have to go to the server stop the website,then stop the application pool and the restart both. We have created a separate application pool for the website.
View 4 RepliesI have a function that converts a .csv file to a datatable. One of the columns I am converting is is a field of names that have a comma in them i.e. "Doe, John" when converting the function treats this as 2 seperate fields because of the comma. I need the datatable to hold this as one field Doe, John in the datatable.

Dim tokens As String() = System.Text.RegularExpressions.Regex.Split _
(reader.ReadLine(), sepChar)
''# add the columns if this is the first line
If Not colAdded Then
For Each token As String In tokens
table.Columns.Add(token)
Next
colAdded = True
Else
''# create a new empty row

Finally
If Not reader Is Nothing Then reader.Close()

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 do have a page that is literally overloaded with about 10 GridViews and there is a datasource for each particular one. Now, each GridView is hide inside a panel, so I only display one at a time depending on what is it that the user request. My concern is the followng: Even though I am only displaying one GridView at a time, do the others datasource are still working behind the scene on the blind side and therefore are putting a load on the server and on its performance. Or I do not have to worry about this because as long as the Panel.Visibility = False, nothing inside that panel is working.

In a asp.net mvc form, im using a radiobutton set, to set a property.
<%=Html.RadioButton("Tipo", "Pizza",
CType(Model.Tipo = "Pizza", Boolean), New With {.id = "Pizza"})%>
<label for="Pizza">Tipo Pizza</label>
<%=Html.RadioButton("Tipo", "Barra",
CType(Model.Tipo = "Barra", Boolean), New With {.id = "Barra"})%>
<label for="Barra">Tipo Barra</label>
I need the CType or i get an overload error. This case seems like the most commom use of radiobutton when working with a Model property. Of course i could create a partial view or a control, but apart from that, is there a cleaner code to accomplish this?
