Forms Data Controls :: Details View - Blocking Multiple Clicks When Updating?
Mar 12, 2010
I have a problem that is driving me insane. I have a simple detailsview that operates as you would expect a detailsview to do - the only difference being that in the updated event I send an email to various people to advise of detail changes (I have conditional testing to do this).
The problem is that if the user goes crazy with left clicking the update button, email recipients can receive multiple duplicate emails.
I have looked all over the net and seen many varied solutions for this problem - mainly using javascript - but none of them seem to be able to block multiple clicks without disabling or hiding the update button - which obviously causes issues with client side validation in the event that information is missing or incorrect.
I had another post about this issue, but decided to modify it to drill down and find the issue. I was doing a master/details, and that was not working, so I have changed it to just a single data source with a single details view created entirely via wizards. The issue is, when I click on the auto generated edit link, and change values in the fields, after clicking update the page refreshes without error but does not update the record. Here is the code:
I'm new to asp.net 3.5 and I have been working through the tutorials using a real access database to learn how to use the new controls. I have an extremely simplistic page setup with a master-details view, the master using the gridview, and the detail using the detailsview controls. Everything seemingly functions correctly, except when I try to update the data in the details view. I make changes to the record, click update and the page posts back but nothing is updated in the database. No errors are given either.
I have a vb.net page that has a editable detailsview. When a user wants to erase the data for a field, they highlight the data, and delete/backspace over it, and click update. However, the original data is still saved. If they are replacing the current data with new data, that works fine and updates/saves correctly. This problem only happens when the current data needs to be removed.
I have on a page a gridview that can be filtered with one text box. I set up the gridview to show select and wanted to then connect a details view so that when you selected a row the entire details would show up. When I run it I get this error. Data keys must be specified on GridView 'GridView1' before the selected data keys can be retrieved. Use the DataKeyNames property to specify data keys.
I have a details view that appears when record is selected in a GridView. Can this details view be opened in it's own modal window that would allow me to use the full event model?
I'm trying to get a record to show up in a details view as part of a Master Details. I was able to get this to work by setting the visibility to true for the Details View in the Page Load event. I now want the details view to show up when the Select button is clicked in the GridView's template field using the onClick event for the button. I don't seem to be assigning the correct properties to get this to work though. what property I should use with this? I know I have to get it from the GridView and assign it to the details but haven't gotten it to work. this is the GridView:
I have a gridview which display when person start n stop the project if same person do muliple projects it save n retrives eaisly i want to do that when i press select in gridview it give me the all about the person means if ali is working on 2 projects so it give me details like ali firsrt project is this time n date this , second project is this how can i do this ?
I have a form that has a detailsview. In that detailview I have and edit button that is visible only when a condition is met. I made the edit command field a template to achive this. My Question is can I have multiple conditions that make the edit button visible. Attached is my current linkbutton with the current variable.
I've scenerio where i've two dropdownlist box (one dependent on other, displays handset brand name and on selection displays the respective model name), two combolistbox which is bounded to their respective datasource(Displays the fault and accessories).
Now i've to update the three tables booking(Handsetid, Brand,model), accessories(handsetId,AcesoriesID) and fault(handsetID,faultID). Ive to update multiple rows in Accessories and fault.
These controls are present in datagridview EditTemplate
I have on one page a grid view that has a a delete bit and create new form, these both work. when the user clicks the edit button/link the id for that field is thrown in the url to a new page with a details view on with its default mode to "Edit". I have a stored procedure to update the SQL dB which works when run in SQL. however when the values are chaged in the details view, I click the update button and it says that it has succesfully updated and throws no errors... It has not?
I think the problem is getting the new values out of the details view. which i have been doing like this...
This gives me what the value that it was before editing and the same as in the dB, this is why i'm getting a successful bool value for the stored procedure. My question is this... how do i get the values after its been changed in the details view?
I have 2 DetailsView controls- dvPerson, dvVehicle - that are bound to datasets at RUN TIME. When a person is selected in dvPerson, dvVehicle should filter to show vehicle info only for that person.
I have written in the old ASP for year and just started two weeks ago with .net, It has taken some adjustments. I am learning using Web Dev Express. Anyway, Here is my question.
I am learning by creating a simple progam to track boxes associated with cases(litigation) IE Smith v Smith case has files in 3 boxes.
So question from a Newbie !So I have a web page with a Details View component for Inserting data into a table.One of the fields is a date/time which I want to be now().SO I guess there are 2 ways of doing it - either I populate the date/time field in the form with a variable that represent now() and make it Read Only so the user can't change it or I somehow make a hidden variable (ie not displayed in the form) that writes a date/time of now() into the database whenever an INSERT takes place.What is the best way and how do I do either of them ? How do I make one of the fields in the INSERT form of the Details View a preset variable ?
in one of the text fields I want to limit what the user can insert to a set of key words. So the obvious thing to do is to present the User with a drop down box to select a key word.
So I have converted the text field into a template and I thought I could replace the <InsertItemTemplate> in the details view with the drop down box.
Well it looks like what I want but when I INSERT the data that field is not inserted into the database.
So I guess I need to Bind the Drop Down somehow to the Insert - How do I do that ?
Am having a details view and grid view in a page. In details view I have one dropdown list with selected index changed.I have to take the values from database and bind it to the other fields in details view. I have Written the Query which is executing fine and fetching values(this one i have checked in SQLServer). But when i select any items in DDL, instead of binding it in DetailsView its getting binded to Grid view.
I have a method that retreives data from table and needs to display in details view. The method is give below: The problem I am facing is I did put some break points to figure out if all the lines are executed but the problem I am facing is that the compiler is not going in the while(reader.read()) loop(I have made to loop bold so that would be easy to locate) and hence unable to retreive data.
public static Workstation GetWorkstationByName(string workstationName) { Workstation computer = new Workstation(); string key = "workstation_workstation_" + workstationName; if (workstationName == null) return null; if (SiteUtility.Cache[key] == null) { string con = SiteProvider.Instance.AltirisConnectionString; List<Workstation> workstationlist = new List<Workstation>(); SqlConnection cn = new SqlConnection(con); SqlCommand cmd = new SqlCommand("Select [Server] from vComputer where Name = '@workstationName';", cn); cn.Open(); cmd.Parameters.Add("@workstationName", SqlDbType.VarChar).Value = workstationName; SqlDataReader reader = cmd.ExecuteReader(); while (reader.Read()) { Workstation ws = new Workstation(); ws.Server = reader["Server"] as string; workstationlist.Add(ws); } string ADSPath = "LDAP://" + SiteProvider.Instance.DomainString;..............
i configured the datasource and and link it with the detailsview but when i run i cnt see the details view...this happen mostly when i changed default mode to edit of read-only..
I have a details view that currently shows the positionID when displaying data in select mode. This corresponds with the way the stored procedure was written. I've decide I want to display the PositionName though. I want to know the best way to do this.
I know I can rewrite the procedure to pull the PositionName instead but I thought there might be another way of doing it. Rewriting the stored procedure to pull the name instead of the ID may be the best way to do this. I thought there was probably a way to cross reference the position Id with the name. If there is then it may be unnecessarily cumbersome and not worth doing.
I also want to be able to pass the id to the Details view when it is in edit mode so a drop down that lists the position names will start with the correct current value selected when in edit mode. This would prevent the value from being accidentally changed. I'm not sure if I rewrite the procedure to return the PositionName instead of the PositionID that it won't cause issues with me wanting the drop down in edit mode to start with the correct value by passing the PositionID. The Position is stored as an int for PositionID in the db.
I am using details view to insert or update record and i am binding it with grid view.when i click on row in grid view for edit it displays the record in details view for edit.How can i dispalay a image in details view?.
I have multiple amounts that I need to display and edit. I am trying to understand the best way to do this..
In MSAccess:
Should I define them as currency or number?
ASP.net
if I use formatting for the field as {0:C}, it works fine in View mode. However, i am unable to update the field in Edit mode for an amount with decimal places. In Edit mode, I can only enter whole numbers(ex: I can enter 123, but not 1.23).
If I set the ApplyFormattingInEditMode=True, I am unable to save data entered in any format($123.23, 123, 123.23, all of them cause the error).
The error I am getting is "Input string is not in a correct format".
