Web Forms :: Update Field With Name Of Signed In User
Jan 13, 2011
Using the form view control, when I click on the edit button to modify a record. the form is in update mode. When I clcik the update button any modified data is posted, but, for some reason the name in one filed named, user_update_name, does not. The name in the field will not change unless the field was empty. For example, if test1 was the last user to modify the record and the user_update_name field was empty, the field was now say Test1. If Test2 modified the same record, Test1 name will still display in the field. The command that fires when the update button is clicked.

On our website users can sign up. The sign up controls (converted to a template) has the usual text boxes and then the create user button. When pressing this button the account is created. After reloading the website, the user can see his credentials in his 'my account' tab. Question: How can we access the newly created user (especially his userid) right after the create user button was clicked? Right now this does not work, we can only start accessing this after the page has been reloaded. But surely the account is created the instant the button was pressed. I have tried this:
But it looks as if the user is not yet logged in at this stage. Can this somehow be forced so that we can access the newly created userid right after the user has clicked the create user button?
I there a way to get the user id that they signed on to the computer with from web site project, without changing IIS so they will have to login? This will be interanet and remote internate users.
Let suppose, I am building an asp.net website which has login scenario in it. I want to provide a certain functionality to the website that if the user is already login on computer 1 and now try to login on computer 2, so he will be allowed to remain login on computer 2, while automatically logout him from computer 1. I also know that http is a stateless medium, so whenever user interact with computer 1 and try to interact with the page, it will get noticed at that time.
In the control Chart, I add few points, selected from the database:
var Diagram_1 = Razrez_D1.Series ["D1"]; sqlDA.SelectCommand.CommandType = CommandType.StoredProcedure; sqlDA.SelectCommand.CommandText = "Razrez_D1"; sqlDA.SelectCommand.Parameters ["@ date1"]. Value = Session ["date1"]. ToString (); sqlDA.SelectCommand.Parameters ["@ date2"]. Value = Session ["date2"]. ToString (); sqlDA.Fill (dataSet1, "Razrez_D1"); sqlDA.SelectCommand.CommandType = CommandType.Text; for (int i = 0; i <dataSet1.Razrez_D1.Rows.Count; i + +) ( string name_s = dataSet1.Razrez_D1 [i]. Name.ToString (); name_s = name_s.Substring (name_s.IndexOf ('№')). Trim (); Diagram_1.Points.AddXY (name_s, dataSet1.Razrez_D1 [i]. Count); Diagram_1.Points [i]. BorderColor = System.Drawing.Color.Black;; Diagram_1.Points [i]. BorderWidth = 1; if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> 5) ( Diagram_1.Points [i]. Color = System.Drawing.Color.Red; ) else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> = 4 & & Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count) <= 5) ( Diagram_1.Points [i]. Color = System.Drawing.Color.Yellow; ) else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count) <4) ( Diagram_1.Points [i]. Color = System.Drawing.Color.Green; ) )
The problem is that the points on the X axis are signed that way: first is not signed, second is signed, third is not signed etc How can I sigh all points?
I developped a light WinForm Control that run like an ActiveX in a Web Page. No problem yet.However, when i want to access System.IO I got a Security Exception. It seems that I have to sign my assembly, so that's what I did. When my assembly is signed, my Web Browser can't show the Winform. I set IE to download any ActiveX in the Security tab ... Nothing happens. Uncheck "Sign Assembly" ... works fine ...
I'd like to add a typical 'Signed in as' bar, cf this site.Since it's 'common', first thought is: master page.However any controls designed on a master page are only rendered 'in' the final page...... so you need the 'this' (Page reference) to access the control... so you can't write code 'on' a master page, whose 'this' is not a Page.HttpContext has Session, Request, etc - all useful but none with a 'Page' reference that I've noticedUpdatePanel looks neat, but I'd prefer a non-Ajax solution to learn the 'basic' way before perhaps later making it 'smarter' with Ajax.Question therefore is: how to write a script that is site-wide, for a master page, that references controls on the (rendered) master page, with or without a 'Page' reference.
There is a field called school which is a dropdown menu, I manually edit items and made it like these: select school, name of 6 elementaries and 2 middle schools, and a high school.I have another field called grade level, which is a drop down menu too, i manually entered the grade items for it: select grade, Kindergarten, 1, 2, 3......12.
I would like after user selects a school in the drop down menu, the field called grade level dropdown box' data source will be updated according to school. For example, if it is a middle school selected, the data source of grade level will be updated to 6, 7 8 grade, if it is elementary the grade will be updated to 1, 2, 3, 4 5 etc. In this way later, when user goes to select grade it will show appropriate grade level lists according to schools.
In GridView (using VB) , I have project information, with Status and %Complete that the user is supposed to update. Trouble is they may change %Complete to 100%, but not change the status from Active to Complete. So, we wind up with a long list of Active tasks that are 100% Complete. How can I force an update to the Status field ? something like... If "%Complete" = "100" Else Status = "Complete" Not sure if I need to do this in VBscript or code behind or SQL or.
I have a gridview that contains a textbox, a drop down, and a checkbox. The commandfield of the gridview has ShowEditButton="true". All of the gridview updating takes place in the "_OnRowUpdating" event. I have a Panel above the gridview with a table and some fields. Everything in the gridview works perfectly, the edit, the update etc., however, when I add a requiredfieldvalidator to the panel above the gridview, the gridview update functionality no longer works. e.g., clicking the update button does not appear to fire. If I comment out the requiredfieldvalidator, everything works fine.
I have a Required field valadator with an update panel and the following settings, also the sql to populate the ddl is at the bottom. I am looking at code I have in another website that works and its pretty much the same.
<td style="background: #dddddd; height: 19px"> <asp:DropDownList ID="ddlFundno2" runat="server" Width="270px" /> <cc1:ListSearchExtender ID="lseFundno2" runat="server" TargetControlId="ddlFundno2" /> </td> <td style="width: 5px"> <asp:RequiredFieldValidator ID="reqPFN2" runat="server" ControlToValidate="ddlFundno2" ErrorMessage=" fund number is required" InitialValue="" Display="Dynamic" SetFocusOnError="True">* </asp:RequiredFieldValidator> </td>
SELECT 0 as FundNo , '' as Display UNION SELECT DISTINCT [FundNo] ,CAST([FundNo] as Varchar(50)) + '-' + [FundName] Display FROM [dbo].[Funds] ORDER BY [FundNo]
I have a gridview where I am using the update. I have converted the label into a templatefield and added a dropdownlist which is getting polulated in the Rowdatabound event. When I test the update i get an error
Cannot insert the value NULL into column 'StartTime', table 'HTC.dbo.EventDates'; column does not allow nulls. UPDATE fails.The statement has been terminated. so I am ussuming its still trying to update from the label rather than using the dropdownlist. here is my code:
I have created a formview with 4 dynamic controls fields that LINQ to a database.
rentfoodutilitytotal
There's an event handle for each of the first three fields whenever a text change with following codes:
' extract textbox from both SubTotal and the modified field tboxSubtotal = FormViewAssistance2.FindControl("totalTextBoxEdit") tboxModifier = FormViewAssistance2.FindControl("foodTextBoxEdit") 'extract string from those textboxes txtSubtotal = tboxSubtotal.Text txtModifier = tboxModifier.Text 'convert text to double and add them together Double.TryParse(txtModifier, dblModifier) Double.TryParse(txtSubtotal, dblSubtotal) dblSubtotal = dblSubtotal + dblModifier 'post the changes back to SubTotalTextBoxEdit 'totalTextBoxEdit 'EditorPart.ReferenceEquals("totalTextBoxEdit", dblSubtotal) 'PostBackTrigger.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal) 'EditorZone.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
I'm stuck on how to post/update totalTextBoxEdit to reflex changes in first three fields without having user clicking Update button to save the information into database. I've tried above 3 statements but none of them is working.
I want To update Mark and i convert it to template Field ,When I press Update I get the Old value not the Newest One of The Mark and nothing were Updated Except The Date Value in each DataBase and Grid
I put a dropdownlist in a template field with 4 choices with the values of each to a,b,c,d and when i run the update query i need it to pull from that selected row,and read the value selected in that field. I tried this:
@choice = SelectedRow.Cells[9].Text.ToString() but it didnt work
how can i extract data from a dropdownlist thats inside a template field and use in a update query?
I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
I have a gridview and sqldatasource in a form. My sqldatasource has select,delete and update command. The delete command is working but the update doest not work when I click the update command field.
Ive got a list of records in a gridview (from an SQLDataSource) where a field value is set to True. I've also added a "reset" button in a template field at the start of the row in the Gridview.
What I would like to do is allow the user to click the reset button on a particular row and 'reset' the true value to 'false' (updating the source data).
I am trying to open my homepage with HTTPS in my test server. Is there a way i can create Self signed certifcates and see if https works. some links or any ideas with how to do Its an ASP.Net project and IIS V6.0
