Codebehind - Passing Arguments To The Server On Button Click?
Jan 12, 2010
I have a ASP.NET web page which contains a table of check boxes and a button. I need to find the IDs of all the check boxes which are checked when the button click happens. Once the list of IDs are collected, it needs to be passed on to the server. I am able to do it using jQuery and PageMethods.How can I achieve this in the button click handler in the code behind file? i.e. the IDs of all the check boxes which are checked when button click happens.
I am having a grid with the three column date, and mode.The last column is Edit.
When i click the edit button, i need to get the corresponding date and mode and show in the pop up. for that it is possible to pass two value in the command ergument.?
I have to submit a form to authorizenet with the information in hidden fields. I'd like to do this on a postback button click as I have to validate the form first.
I'm trying to seamlessly log in the user without prompting for credentials as part of a <asp:Wizard> process. My strategy is to handle the NextButtonClick event and login the user in code. I already have the user's credentials saved in session variablesIs it possible to login a user in code? Will a hidden <asp:Login> control behind the scenes be required?
I need to pass 4 arguments (3 strings and one comma separated list) from an ASP.NET page to another ASP.NET page using jQuery. The destination page ought to be launched as a separate window, which works fine with the following jQuery snippet:
How can I pass the arguments to the destination page? I am trying to avoid the query string to pass the arguments because:
I don't want to show the url arguments (which can also be very long) in the destination window. There are some special characters like ',/,, & etc. in the string arguments.
Edit: I'm trying to access the arguments in the script section of the aspx file i.e.
<script language="C#" runat="server"> protected void Page_Load ( object src, EventArgs e) { //Creating dynamic asp controls here } </script>
My specific need for the arguments in the Page_Load of the script section stems from the fact that I am creating a few dynamic Chart controls in the Page_Load which depend on these arguments.
I tried using Ajax & Jquery for the following need, but not able to do...
I have Two Forms StringMain.aspx & Returner.aspx.... I have created 4 Divs at StringMain.aspx and a sample text "ToCheck" at First Div.. In the Returner.aspx form page load, i placed a label like this
I have set StringMain.aspx as default running page. So When i run StringMain.Aspx page,
the text i placed in the First Div "To Check" should concat with the label Text "hello" of Returner.aspx and display it together in the First Div of StringMain.aspx like this
I'm using a grid view to display a number of records from a database.
Each row has an Edit Button. When the button is clicked I want an ID to be passed back to a funtion in my .cs file. How do I bind the rowID to the Button field?
I've tired using a hyper link instead but this doens't seem to work because I'm posting back to the same page which already has a Permanter on the URL.
I'm designing a sort of hierarchical system, as follows:
Contract Master Commodity Commodity Sub-Commodity Part
Each one of these are on their own page (for now). The user starts out on the Contract.aspx page. If they want to see the Master Commodities for the contract they are currently on, they will click the "ImageButton" I have set up, and I pass in as a command argument the ContractID (CommandArgument='<%# Eval("ContractID")%>'). This works great- I get to my Master Commodity page with the Master Commodities filtered on the ContractID I passed in.
Here's my problem: Navigating from the Master Commodity page to the Commodity page will (I think) require passing in the ContractID (so we JUST see stuff for the contract we're on), AND the Master Commodity ID (so we JUST see the Commodities that are related to the Master Commodity). I've tried the following: CommandArgument='<%# Eval("ContractID") + ',' + Eval("MComID")%>', but as you could probably expect, that doesn't work. If I can just do something like above and have a delimiter like the comma, I can go from there and make it work.
I'm attempting to use a Button's OnCommand method to handle it's click event so that the event is passed on to OnPreRender method as shown below. So basically the OnPreRender method is called upon a button click. I'm need to use the OnCommand method because I have 2 buttons.
CS0123: No overload for 'groupSearch_PreRender' matches delegate 'System.EventHandler' So basically groupSearch_PreRender only takes an EventArg. I've tried casting as shown below but it doesn't seem to work. How else can I pass the button click event to the PreRender method?
protected void groupSearchView_PreRender(object sender, EventArgs e) { CommandEventArg entry = (CommandEventArg)e; //casting to CommandEventArg if(entry.CommandName=="searchUser") { do stuff } }
I have a datareader that returns a few fields (orderid, customer id, customername, location, total amount - as an example) that is bound to a datagrid on an asp page. The datagrid simply displays customername, location and total amount and has 2 buttons
below it labelled 'Add New' and 'Edit' and I would like the following to happen:
1) when a user clicks on any cell in the datagrid, I want that row to be highlighted in someway so that the user is aware of the highlighted row.
2) If the user then clicks on Edit button, I want to go to another page that displays the details of that order by passing the orderid of that row to the next page.
The idea is that the user selects a row on the datagrid and then clicks edit which will take them to another page where they can edit/updated details but I'm not sure how I can pass a value of a selected row in a datagrid to another page. I am aware that you can add a template column with buttons on but I would like to have one set of buttons rather than have buttons on each row of the datagrid.
When i execute this SP in DB, it works fine. But when i execute from asp.net app it is throwing error: Procedure or function ... has too many arguments specified
GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROC [dbo].[sp_Customer] @brchID char(40), @brchName VARCHAR(50), @userID VARCHAR(50) AS BEGIN TRANSACTION DECLARE @req_pk int DECLARE @customer_org_pk int IF EXISTS(SELECT * FROM [customer] WHERE [org_id] like @brchID) BEGIN SELECT [org_pk] FROM [customer] WHERE [org_id] like @brchID END ELSE BEGIN EXEC sp_get_next_control_no 'organization.org_pk',@customer_org_pk out; INSERT INTO [customer] (org_pk,[org_id],[org_name]) VALUES(@customer_org_pk,@brchID,@brchName) SELECT [org_pk] FROM [customer] WHERE [org_id] like @brchID END --Address Book Entry IF NOT EXISTS(SELECT * FROM [address_book] WHERE [prsn_id] like @userID) BEGIN exec sp_get_next_control_no 'person.prsn_pk',@req_pk out; END IF (@@ERROR <> 0) BEGIN -- Rollback the transaction ROLLBACK RETURN END ELSE BEGIN COMMIT END
Here is my asp method:
public static string Customer(string brchId, string brchName, string userId) { string spName = "st_Customer"; SqlParameter OrgPk = new SqlParameter("@org_pk", SqlDbType.Int); OrgPk.Direction = ParameterDirection.Output; OrgPk.Size = 50; try { SqlHelper.ExecuteNonQuery(Config.ConnectionString, CommandType.StoredProcedure, spName, new SqlParameter("@brchID", brchId), new SqlParameter("@brchName", brchName), new SqlParameter("@userID", userId), OrgPk ); return Convert.ToString(OrgPk.Value); } }
I'm trying to use the codebehind to add a click event to a TableCell..I basically want the user to be able to click a cell and cause a server side click event so that I can call a method with the GUID of the item in the cell...seems this functionality should already be built-in but I've been unable to find much in the way of instruction
I want to run code at the server(sql update) on a client button click, but i dont want a postback (more specifically, page flicker or loss of scrolling position).
how to run multiple queries on a single button click. Actually I want whatever a user write in text box and click the button the text would get inserted in table category and also a table name project should get updated. I am using Sql server 2005 and c#
I know this is strange, and probably considered bad design. I need to simulate the clicking of an actual button on my asp page. I do not need the button's on_click event sub/code to execute. The issue here is that I want to trigger the ConfirmButtonExtender associated with that button. The ConfirmButtonExtender, by design, executes before the Click event code.
So to be clear, I need to actually "click" the button. What the button does is irrelevant (in fact the button is invisible and has no code). I simply need to trigger the button's ConfirmButtonExtender, not the code behind the actual clicking of the button. Like this..
Protected Sub Button1_Click(.....) Handles Button1.Click Somehow click invisible_button (not call the Click() event, but actually "click" the button) End Sub
----Long, convoluted details------
I have fields on a page that require user input. When the user hits submit, I want to display a confirmation dialog with the data of those fields.
To do this, I originally added a ConfirmButtonExtender to the "Submit" button (just a regular ASP button). The problem appears because the ConfirmButtonExtender executes before the OnClick event of the submit button.
During my OnClick even I took the data, populated it into a confirm textbox (which is inside a ModalPopUpExtender). I originally then used the MPE.Show() (still in the onClick event) to display my conformation textbox.
However ,the .Show() function doesn't halt code execution (which is needed, since this is a confirmation dialog). So as a result, I created an invisible button.
This invisible button now has the ConfirmButtonExtender added to it, which will display my MPE/Confirm Dialog. When the user hits "Submit", the click routine is called, all the data is stored and populated, and THEN I want to "click" the invisible button, triggering the ConfirmButtonExtender. That will halt code execution in my original Submit buttons click routine.
from above code i use UpdatePanel but when i am click on Button the request doesn't goto server but i want to send request to server.. how can i do that
In .net application, I am using HTML button to save data. How can one Save data in SQL-Server on click of HTML button. Moreover, before Saving I also want to check if that User is not already registered by checking Email ID. I know, how to do that using .net button Control but couldn't make out how to do that using HTML button. I require HTML button since there are some HTML fields whose value gets blank as soon as page is postback(which happens if I use .net button Control).
Now I must run cmdSave_Click() before the cmdConfirm.Attributes.Add even though both is for same button anyway. I know that client side script will try to run first but I must run the cmdSave_Click event first to save the data. Aftre that cmdConfirm.Attributes will send the Name to the next page using a Javascript function where the stored values(stored using cmdSave_Click) will be used. I have no other choice. I cannot run the Javascript function first as it will happen before the data is stored. And also I cannot use another page as all has to be performed in one page so that user will not have to click Save twice. Can anyone tell me How I can delay the cmdConfirm.Attributes.Add until the cmdSave_Click is performed.
