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)
I have four textbox and a button in my page. After filling the textbox. When the user click save button. A loading image should be displayed. User should not feel that the page is postback to the server,Some thing like in facebook loading image.
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.
I searched google and found asynchronise post back trigger is used if we want update panel to post back on some event of control if it is out side the update panel. Than what is purpose of post back trigger ?
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).
I have a gridview inside update pannel and i enabled sorting for the grid if i click to sort a column it does postback and then the grid doesn't show in anather way i have item template column inside of the grid and i am using a button to call a function ,if i click on this button it do the function but the grid doesn t show after the post back
- 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.
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?
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?
I have a very odd and disconcerning problem. Just recently a page where I have 1 textbox and a buttoon has ceased to work.
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.
The pages is
[Code].... [Code]....
The page is "POST", but isPostback is false[Code]....
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)...
If the grid column is clicked to sort i dont want to retireve data agian, i can get it from viewstate, but i dont know if that triggered the post back or if the ImageButton on the page triggered it
I have a gridview that displays pending cases. I have enabled paging and sorting on any column. By default it loads data sorted by CreatedDate. When I sort it on any page by company name it does the sorting, but when I move to the next page, it looses sorting by CompanyName. How do I hold the sorting across all the pages on the grid?
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()); }
I have a third party company that we need to allow they users to pass into our website without loging in. TO keep it easy I was thinking of having them post to a custom login page on my site.
So their code would be something like this:
[Code]....
My landing/login page would do soemthign liek this.
[Code]....
My question is whether there are any security issues when using this kind of method? I am not sure yet what their site is written in. I figured that they could figure out how to do the post as long as I have the landing page for them and there is no security issues.
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.
I have a textbox that is used for searching. upon clicking the ok button and posting back, the function is called, and gets matching results by using sql query in the aspx.cs file this information will be displayed in the div tag and set visible. initially div tag will not be visible. after the button posts back, then the div tag will be set visible.
I have a user registration form. Here I have link to another page (card info page) which has to be filled for the registration. User fills the few fields in the user registration form and click on the link that takes to card info page. When user clicks the link in card info page to navigate back to registration page, the previous details entered in registration got vanished. So I need to redirect from card info page to registration page without postback. How can i accomplish that?Response.Redirect() is used for redirection.

I am currently a beginner in asp.net i am currently watching msdn videos of "beginners developers learning" i am on the topic of application state so i got confused on a topic of "cross page postback" can anybody explain what that is
and another thing is "profile" object we use it in web.config file
I'm using a asp file upload control, however, when other controls trigger some post back actions, the file upload value return to null...any sample code i can follow please?
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.
