Reference Datatable Row Without For Loop?
Jan 6, 2010I have a datatable with 1 record only, can I reference the data in the row without a for loop? I can get to the data by using the following code, but it would be nice if I didn't have to use the For loop.
foreach (DataRow row in dataTable.Rows)
{
string name = row["Name"].ToString();
string id = row["ID"].ToString();
}
I have only one row therefore may i get its records without for loop or foreach loop

C# - How To Bind A DataTable With Complex Data Objects To A GridView
Jan 31, 2011My DataTable is programatically generated, and contains objects of type JobInstance in the cells.
[Code]....
When I bind this DataTable to an ASP GridView, it only displays the first column. But if I remove the "typeof(Job)" when creating the column (the line with // !!!), the GridView displays all the columns by showing the result of JobInstance.ToString() in the cells. However, I have no access to the underlying JobInstance object, only the string values that are being displayed.
I need access to the JobInstance object when displaying the GridView (for example in the OnRowDataBound), because I want to access the fields inside JobInstance for each cell to determine formatting options, and add other links in each cell.

Forms Data Controls :: Loop Through Different Sets Of Rows In A Datatable?
Oct 13, 2010I 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"]))

The problem is 'Null' values in the datatable don't show up as empty tags in the XML so when I read the XML from the web service this is no consistency. Is there a way to show the tags even when the fields are null in the datatable or is there a better way to accomplish what I need.
