Forms Data Controls :: Join Two Datatables Codebehind Page?

Aug 2, 2010

I have two datatables with datavalues

datatable A

ID data1 data2 data 3

datatable b

ID data4 data5 data6

I would like to merge datatable A and datatable B like so the resultset is like this in tableC

ID data1 data2 data3 data4 data5 data6

When my code finishes the column names are in this format but the data from dt b is pushed down into new rows instead of added on as new columns.

i used merge method but it giving like the bellow

example:

ID data1 data2 data3 data4 data5 data6
1 X X X
2
3
4
5
1 X X X
2 X X X
3
4
5

Forms Data Controls :: Caching DataTable - Create/cache Multiple DataTables?

Jul 23, 2010

Among the many aspects of asp.net that I haven't focused my development on yet is caching. I have a perfect application for it now, I think, with a GridView that sits inside a repeater, and is bound in the Repeater ItemDataBound event. The contents of the GridView will remain static for each Repeater data item for each Client. The nature of the data in the GridView is that it can change from day to day per Client, but wouldn't need to be refreshed more frequently than that. The Page istelf only deals with one at a time Client based on a QueryStringParameter. My questions are a) how do I cache the DataTable so that a call to the DataBase isn't made each time Repeater item is bound and b) can I create/cache multiple DataTables (one for each Client) and let them live for day, checking for existence before calling the SQL stored procedure to regenerate the data?

My DataTable method: [Code]....

As of now I am looping thoruh all the rows. Is that the only solution or is there any best way to do this ?

Datatables - Two Tables On One Page?

Jul 31, 2010

My project is in Asp.Net Webforms using C#.

On one of my web pages, I want to have two tables. One is going to be a summary table and the other a more detailed breakdown of the summary. When the user clicks on one of the rows of the summary table, I want the corresponding breakdown rows to appear in the breakdown table.

These tables can have anything between 60 and about 500 rows.

I have thought of two possible ways of doing this and I'm not sure which is best, or if there is another, better way of implementing this:

1) When a user clicks on one of the rows in the first table, a postback event happens, and the data for the second table is loaded from the code behind.

2) When the webpage is loaded for the first time, both tables are filled with all of the possible data, but all of the rows in the second table have the "display: none;" CSS attribute. When a user clicks on a summary row, the CSS of the corresponding breakdown rows is changed using JavaScript.

Web Forms :: Controls Cannot Be Focused On Until Add To Page In Codebehind

Jan 12, 2011

What is the earliest time that a control can be focused on without causing an exception/server error? It seems that newly-created (in codebehind) controls cannot be focused on until they're added to the page (or another container on the page), but I'd like to confirm and make sure.

Web Forms :: Getting Data From Control In Parent Page Codebehind?

Jan 19, 2011

I am creating an ASP.NET website in Visual Studio 2010 (.NET 4.0) in C#.

I have a user control applicant_information.ascx which contains text boxes.

The page application.aspx contains this user control:

<%@ Register src="controls/applicant_information.ascx" tagname="applicant" tagprefix="uc1" %>
<uc1:applicant ID="applicant1" runat="server" />

The application.aspx page contains a multiview, and the applicant1 user control is in one of the views. The button continue takes the visitor to the next view which contains another user control of text boxes.

I want to write validation code on the continue_Click event which is in the application.aspx.cs page. Ideally, from the application.aspx.cs code behind page, I want to get the user input from a text box in applicant1.

Intellicense cannot seem to find any of the text boxes in applicant1 from application.aspx.cs.
