DataSource Controls :: How To Choose Default DataTable From DataSet For Binding With A DataGrid

Dec 13, 2010

I have a DataSet with multiple DataTables and I use an ObjectDataDataSource to bind my DataGrid to it. One of my tables is correctly displayed in the grid. My problem is, that the grid displays the wrong table.

My tables are related to each other - I make use of the "relation" objects in VS Studio 2010. My ObjectDataSource points to a class with a select method. The DataSet contains several DataTables (e.g. "Variables" and "Components").

[Code]....

How can I configure the DataSet to display the table "Variables" by default?

Forms Data Controls :: Dynamically Binding Dataset Table Values To Datagrid's Header Column?

Jun 29, 2010

I want to dynamically bind dataset values into datagrid's header datafield.

Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.

i.e like ds.Tables[0].Rows[0][0].

Is it possible to do it in Datagrid ItemDataBound function like,

e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]

or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

Silverlight Grid Binding - Dataset/Datatable To List?

Aug 10, 2010

We are in the process of migrating our current asp.net gridviews to silverlight grids. The challenge that I am facing here is that in the gridview, the grid is bind to a dataset/datatable. But in silverlight, I do not have dataset/datatable available in the silverlight class. So only option is to create a Webservice and convert the dataset that I am currently getting from business layer to a class that imlements IList<> (unless there are any other ways). Now to convert this dataset to Ilist, I have to loop through the dataset to load the List. In my current dataset I have almost 10,000 records or even more in some cases. So the response time will be really slow.Are there anyways to

1) Load the List from dataset directly without looping through ?

2) Fetch the data from database directly to a List without having loading the dataset ?

DataSource Controls :: Use DataTable Instead Of DataSet / Returning One Table?

Apr 9, 2010

I'm returning one table. My understanding is that a DataSet can be made of more than one DataTable. I also understand that I can use either of these to return my one table.

Is it better to use the DataTable when I have one table to return instead of a DataSet? Is there any advantage of not using the DataSet in a situation like this? Is there a disadvantage to using the DataSet when only one table is being returned? Does this even matter?

DataSource Controls :: Datatable/Dataset Total Memory?

Mar 16, 2011

make a query which will give me 200,000 results and bind it to the datatable but the error will pop out saying out of memory or request timed out.Can datatable/dataset handle these records or is my current server's hardware needs a little upgrade?Actually we are gettings millions of data and i dont have any idea how to solve this one? Have you worked on this kind of data? Do you have any idea on how to send my command from server A to server B while server A also processing request and will not wait for server B's result and server B will just update the records in my database, i think this can solve my problem if doing it in parallel.

DataSource Controls :: Default Value Or Binding With Newid?

Jun 18, 2010

I've created a table with a userId column of type uniqueidentifier, and have set that column as the primary key. In the column properties, under the Default Value or Binding, I've put (newid()). I thought that this would create a new uniqueidentifier if no value is specified in the insert statement.

However, when I try to add a new row in the table data view and leave the userId blank, it does not let me add the row. It gives me an error saying that the value cannot be NULL (since it is a primary key), however I had deliberately left it NULL so that it would add a new value by calling newid(). Have I made a false assumption?

DataSource Controls :: Create Interface For Adding Users - Datatable Or Dataset

May 3, 2010

I need to create an interface for adding users to .Net Membership DB through an existing database. My Idea is to read each row from database from existing users table in a datatable and then iterate through each row and add it to new database. I cannot directly copy the rows from existing users table because the password stored in .Net Membership provider is in ir-reversible hash code and hashing is done through encryption algorithm present in front end code. My User count is huge (in millions).So what should i use to read the records, Dataset or datatable. Also tell what is the max number of rows it can hold.
