C# - Hold Temporary Information In Gridview Before Post Back?

Mar 28, 2011

I have a Dialog (Modal), where I'll register one (or several) contact.

the contact goes to a gridview, where they may be edited or deleted.

the data in the Gridview, can only be saved in the database at the end of the process.

How can I achieve this?

Modal code

[Code]....

OBS.:

I don't have a good sample of CSharp or html code, 'cuz i don't know how to achieve this. All my code look messy atm (trying a lot of things already) My GridView is an ascx, and the modal is in the same ascx. I belive some temporary table, or something like this will help, but i never did something like it (looks like a shop cart software), and i don't even know how look for it.

EDIT:

i did this code:

CSharp code:

[Code]....

i create one temporary gridview, but the data is empty, i tried pull it from my text in the modal, but i was not able to, i'm i'm not familiar in how i'll get the data from gridview to my database. (i believe this is the easier part, then i not focused at it in the moment)

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.

Web Forms :: GridView's CSS Lost After Ajax Post Back?

Feb 24, 2010

I have a css file which is external registered in Master Page which contents the following code :

.Item:hover
{
background-color: #def2fd;
font-weight: bold;
cursor:pointer;
}

The Item is applied for GridViewRow. This GridView is in a UpdatePanel, when I click a button to do a Ajax Post Back the CSS applied for the GridViewRow is useless (IE 6 only).

AJAX :: Dynamic Image Buttons In GridView Not Doing Partial Post Back?

Sep 9, 2010

watch here:

- Create a gridview with AllowPaging and AllowSorting = true
- On page load, I bind it to datasource (in my case a webservice)
- On gridview's rowcreated event, I dynamically add image buttons on the header of the grid for sorting (up/down arrows). On header I have column name and the image. I removed the Column name default sorting link. So user can now only click the image button for sorting.
- Call sorting method

This works perfectly fine without AJAX. The paging, sorting works fine. Also when I apply AJAX the paging works fine. But the sorting is doing a full post back instead of partial postback.

I have my gridview within UpdatePanel and Triggeres is set on gridview sill it doesn't work.

Forms Data Controls :: Gridview Doing Post Back And Loosing Settings

Feb 22, 2011

I have three identical procedures that are all used to open the contents of a GridView into Excel. One was working fine but the other two were getting a 'RegisterForEventValidation can only be called during Render();' error when attempting to run the form.RenderControl(html) command. The only difference I saw was that the one that was working had the allowsorting value set to 'False' where the other two were set to 'True'. I set the other two to false and they worked. So what is going on here? Why would this cause the error; is the GridView somehow doing a post back and loosing settings when this value is set?

Web Forms :: Scroll Back To Drop Down List After Auto Post Back In Code Behind?

Feb 22, 2011

Using Vb.Net 2003 Asp.Net 1.1

I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.

Problem is: when the page comes back it is at the top of the page not where i have the control.

I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.

Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.

I really don't want to use Page.Register new Script...... code if I can avoid it.

What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.

Forms Data Controls :: Persist HTML Input In GridView On Post Back?

Nov 11, 2010

I have a GridView control that has an ItemTemplate that contains an HTML radio button. In my code behind I am querying a database, retrieving a column of values, and then binding the list to the GridView. My problem is that the radio button that I select is not being persisted on post back. I have tried using an ASP RadioButton rather than an HTML control, but when I do that all of the radio button can be selected at the same time (i.e. like check boxes). how to persist the radio button that is selected in this scenario?

When I look at the post coming into the PageLoad, the pageType is "POST", but the Page.IsPostBack is false!! and the textbox (which had content) is empty.

I have stripped all AJAX script out, so I have a very vanilla page (in a master page) being served.

Data Controls :: Add Dynamic Rows In GridView With TextBox And Keep Edited GridView Row Data On Post Back

May 7, 2015

I have 3 textboxes , 1 dropdown , 1 Button and 1 gridview .

Textboxes ID are :ACode , ADesc , ASeq
DropDown ID is :CPhase
Button ID is :AddRowBTN
GridView ID is :PhasesTempGrid

Now whats the story is ?After adding some data into textboxes , when a user clicks ADDRow BTN , that data gets saved into datatable , then that datatable gets binded to gridview and it shows my textboxes data in it .

What i want to achieve ?In my gridview i am use templateField and inside that template field there are textboxes ( Let the users edit the row without clicking any button ) .

Take an example of dummy data and problem persisting in there :for e.g i put some data in textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"Then i click Add BTN , it saves the data in datatable and show in gridview , now if i do this in gridview :ACode = "Edited ABCD"ADesc = "Edited EFGH too"ASeq = "WoW There"Then i click Add BTN , it removes the edited record in gridview and shows original data which had came earlier from textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"I don't want that to be done ... Simple is that user can enter data from textboxes , click the btn to submit into grid then he can edit the data like he want ... data must not get flashed , here's my coding i have done so far : 

public void AddNewData()
{
var dt = new DataTable();
if (ViewState["myDatatable"] != null)
{
dt = (DataTable) ViewState["myDatatable"];
}

[CODE]...

here i havent added dropdown combo in gridview but you can do it so that it will save my time (Bind it just the way PhaseDropDown have bind)...

MVC :: Keeping Track Of User Information Between POST And GET?

Dec 28, 2010

The Register action gets called in the Account controller, showing the RegisterViewModel in the Register.aspx view. The form in Register.aspx is submitted/posted with answers to all of the form questions, except for the security question answers. If the user is created successfully, then I'd like to go to the GoToSecurityQuestions view using the code - return RedirectToAction("GoToSecurityQuestions", "Account"); I need to be able to keep track of the user name or ID of the newly created user so that I can persist the security questions to the database records related to the user. What's the best way to keep track of the user info between the [HttpPost] Register( ) and the [HttpGet] GoToSecurityQuestions( ) ?

[HttpGet]
public ViewResult Register()
{ return View(new RegisterViewModel()); }

C# - Uploadify - Passing Information Back To The Original Form?

Mar 3, 2010

I have an Send.aspx page that has an uploadify control on it. Upload.ashx handles the file upload.I am adding a file record to a sql database in the Upload.ashx file and I need to get the ID of that record back from Upload.aspx when it is done.Can't get it working with Sessions. =( Something to do with an Adobe bug?

What would the best way to handle this be?Here is the uploadify control:

<script type="text/javascript">
// <![CDATA[
var contestID = $('[id$=HiddenFieldContestID]').val();[code]...

This took a while for me to figure out. But in retrospect it is extremely simple. For this reason, I mad a video tutorial to help newcomers get started quickly and understand how this awesome control works.

Web Forms :: How To Get Post Back Value From Fields

Dec 30, 2010

Beginner question:

I'm not sure if this is specific to Telerik's plug-in I'm trying to use or if it's a 'generic thing' I'm doing wrong ?

I have a RadTextBox:

<telerik:RadTextBox ID="RadTextBox1" Runat="server" name="nameTest"/>

And I have an ASP button that run this code:
Dim a As String = Request.Form("nameTest")
Dim b As String = Request.Form("RadTextBox1")

Both a and b always remain null.

Questions
- How do I get postback values from Rad/components ?
- How do I get postback values from Rad/components when they are in user control ?

Attributes Clear On Post Back?

Jan 14, 2010

I am using Attributes.Add("style","color:green") with some checkboxlists and radiobuttonlists. When I click one of the checkboxes and I do the autopostback the attributes clear out. So I would think someone already has a sub to fix this. Something like:

SaveAttributes(checkboxlist1) or SaveAttributes() 'which would loop though all controls and save the state.

and then on pageload it would have

LoadAttributes(checkboxlist1) or LoadAttributes() 'which would loop through all controls and restore the state.
