Persisting Datable On Post Backs

Mar 16, 2015

I am retrieving results from a SQL database based on a user file upload, and I am saving the returned results in a datatable. It can be up to 15,000 rows. I need to use this datatable in other requests in this same page - i.e. saving the data back to another table, exporting to a file....How can I store the datatable to access again? I read up on viewstate, session , and cache, but they all seem to have an affect on performance and memory.

I have a situation where I want a user to select a file, then select an option from a DropDownList. When they select an item from the DropDownList I do an auto post back and do some stuff with the file, but this causes the path to clear out. Is there some way that I can keep the path from clearing out?

MVC :: Retain Partial Data In Model Over The Post Backs?

Oct 12, 2010

I have recently started learning ASP.NET with MVC 2 Framework, I am facing difficulties in the following scenarios.In my MVC application I want to retain partial information in Model over post backs.Following is my scenario,

1. I initiate "Edit" of main record by clicking date hyperlink from left navigation.

2. Amend some data.

3. Save the record.

4. "Edit" sub record of the saved record by clicking another hyperlink from bottom left navigation panel.

The page is divided in to 6 tabs, the first 5 tabs shows the data for the main record and the 6th tab shows data of sub record. Wehn we "Edit@ sub record the previous 5 tabs doesn't have any changes noted, that means there is no harm in keeping their details intact in the main model. So is there a way to access model in the controller on hyper link click action so that I can only load the data for the clicked sub record (I am asking this, because the hyperlink click uses HTTP GET method so no model parameter passed in action method). If no, then how do I retain partial values in the Model over post backs?

Note that each tab data have been kept in individual models, and a main model has a collection member to hold all these individual models together.I thought as the model is binded with the view, it is too binded with controller. But it is allowing easily to access model in variable "Model" for the view but not for the controller.

SQL Reporting :: Reportviewer Sorting Fails In Successive Post Backs?

Jan 19, 2010

I have created a rdlc file (Binded its columns accordingly, sorting is enabled on few columns) and rendering it using a reportviewer control. Everything works fine while loading report first time; it shows the progress indicator & loads it correctly. When I click on sort_button(default shown by control itself) it sorts correctly. Now successive clicks on sort_button shows error :

An error occurred during local report processing. An internal error occurred on the report server. See the error log for more details. Gone through the log at server:

Program FilesMicrosoft SQL ServerMSSQL.3Reporting ServicesLogFilesReportServerService__01_19_2010_01_34_05.log but not able to deduce any fruitful exception.

Trace value in config file is set to :< add value="3" />

Either disable the sort_button till the report loads completely. Or show the progressbar indicator till the report loads completely.I am not able to find out the solution for: how to achieve any of the two ways mentioned above.

Asp.net - Use Of Eventargs In DoPostback Function?

Feb 10, 2010

This may be a basic question. I know __doPostback() function accepts 2 arguments, eventtarget and eventargs. eventtarget is used to identify the control that causes postback. Then what is the use of eventargs in doPostback function?? I saw the _doPostback function always set the __EVENTARGUMENT hidden field to nothing for any postbacks caused thro controls with even autopostback to true or a control like linkButton.

Web Forms :: Why Does Init Occur From The Bottom Up

Mar 3, 2010

I'm referencing this article:[URL]Specifically, this line:

"The Init event for each child control occur before the corresponding event is raised for its container"

I've never noticed this behavior before, but can definitely see that this is correct. I don't understand WHY this is necessary though. Can someone shed some light on this?

C# DoPostBack Function Is Not Appearing In The Html Code?

Oct 5, 2010

I have a form with multiple dropdownlist and each list has onselectedindexchanged defined.

<asp:DropDownList ID="SPR" runat="server" OnSelectedIndexChanged="Reload_OnSelectedIndexChanged" AutoPostBack="true">
<asp:ListItem Text="1 day" Value="1:D"></asp:ListItem>
<asp:ListItem Text="5 days" Value="5:D"></asp:ListItem>
<asp:ListItem Text="1 month" Value="1:M"></asp:ListItem>
<asp:ListItem Text="3 months" Value="3:M"></asp:ListItem>
<asp:ListItem Text="6 months" Value="6:M"></asp:ListItem>
<asp:ListItem Text="1 year" Value="1:Y"></asp:ListItem>
<asp:ListItem Text="2 years" Value="2:Y"></asp:ListItem>
</asp:DropDownList>

So when I run the page I expect to receive the postbackcode and the select code with the onchange property defined.

When I invoke the pages in Explorer, Safari or Chrome everything works fine but in Firefox the __doPostBack function and the onchange property in the select tags are not defined. Why is that?

Web Forms :: RequiredFieldValidators Are Allowing Postback To Occur?

Jul 28, 2010

I'm adding multiple TextBox and DropDownList controls programmatically on Page_Load. Some of them have attached RequiredFieldValidators that are being built programmatically as well. The issue I'm having is that when the Submit button (also added programmatically) is clicked, a postback occurs before the RequiredFieldValidators mark their respective fields as blank. How can I get these to fire client-side like they're supposed to?

Web Forms :: Create Via C# In An Event Causing Page Validation To Occur On Postback?

Feb 14, 2011

I'm having trouble with an image button I create via c# in an event causing page validation to occur on postback. The CausesValidation attribute is set to false at time of creation in the event. I also wire up the Click event in the page_init with postback so not to loose the event handler if the page posts another way. Here is the code I'm using in the click event of a Button. I've also tried to enable and disable viewstate for the button with no luck. What am I missing here that continues to fire page validation in the Click of this imagebutton?

SQL Server ::error Occur Paste The Generated Query Into Sql Management Studio?

Aug 4, 2010

I have been using a function that replaces some characters from my editor in asp.net with '+CHAR(x)+' to chain together a string with characters such as single quote that would otherwise break the query, i know how to escape the character using double single quote but i was wondering why i get this problem.The problem is that when the string gets too long about 7kb to 8kb its gets cut off for no reason, no error message gets displayed, the query is successful only the string cuts off at a point. When i escape the character without using '+CHAR(x)+' to add the character i can add a very long string that does not cut off,i am using Varchar(max) for my field, (have also tried text).I am using sql 2008 express edition, and encounter this problem when i paste the generated query into sql management studio, and when i execute the query fromasp.net code.

C# - Using A Timer Post Back, Which Controller To Use That Doesn't Post Back To Server?

Jul 14, 2010

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).

Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?

Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.
