DataSource Controls :: Prepopulated Form Not Updating Correctly?
Apr 28, 2010
I've created a page called "EditItem.aspx" where a user can edit a row in a database. On EditItem.aspx.cs, the pageload function grabs the correct row from the database (by grabbing the querystring in the url). The form is populated with all of the correct data. I've got a button onclick that runs this code:
[Code]....
But the changes do not apply. However, if I set static information (so the information is not being grabbed from fields on the form) into the SQL string, I can click the button once, nothing will happen, but if I press it a second time, THEN the information will be passed to the database.
I'm using a GridView to retrieve data from a stored procedure using a SQLDataSource (db is SQL Server 2008). When I compile my application and go to my website, all the data is loaded and shown fine. If I was to add a new entry to the table however (a seperate page on my website has a Wizard control to facilitate this) and then return to the page with the GridView, the new entry doesn't show up.
Looking from SQL Server, the data has been added, but the GridView isn't updating to show it. If I were to recompile the project with F6 and refresh the page, the new data will show up. I tried calling DataBind() on the GridView in the Page Load event, however the issue still remains.
I have a GridView in ASP.NET. I have an Edit CommandButton for every line in the GridView to edit the data on that line. All of this works fine except for the fact that when the user clicks on Update, it does not update with the correct value that the user entered. I have this as a Template field with the textbox to edit bound to the field, so it updates when the user changed the value and clicks Update. However it does not work. I have tried almost everything and its very frustrating. Here is the code for the Data Source:
<asp:SqlDataSource ID="Table1DataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString2 %>" InsertCommand="INSERT INTO TABLE1(ProjectId, WBS, WBSTitle, VersionId) VALUES (@ProjectId, @WBS, @WBSTitle, @VersionId)" DeleteCommand="DELETE FROM TABLE1
In the following code, the user documents types are not getting updated, they do initially but don't stay updated. perhaps you can see something blatant here:
I have a page with an updatepanel, which at runtime has controls dynamically created. The controls are saved within the cache, and readded to the page upon postback each time when needed. Sometimes the controls need to change, sometimes not. In most of my cases, if I just re-add the control to the page without any changes to the control AJAX will leave the control alone on the client-side leaving me with what I expect to see, which is no change. If I make a change, it obviously updates correctly.
Now, I have added a literal control which defines an iFrame which points to another page. ie:
If I re-add this control on postback, with a change, I get the item on the page as I expect. If I make no changes to the .Text and simply re-add the control to the page, it flashes as though it has been changed and then re-requests the page defined by the src. The whole point of me caching this, is to stop the client-side from updating a control that has not changed, removing a flashing screen and all the resizing that goes with it.
I have a gridview which contains a dropdownlist inside a TemplateField. The ddl appears correctly and seems to work ok but it isn't updating the table despite being bound to a field.
There seems to be something wrong with the create user wizard?I am using hashed password storage. When I change it to clear storage I see the user's password is being stored as something completly different than what they typed in.Example: changeme1 now equates to something like: 4W*KQQ4%=SIf I use 4W*KQQ4%=S as the password to login with it works but changeme1 does not.When I use the reset password wizard it updates the password just fine and it works when I login next.Any clues what could be causing this?
I have a query that looks like this attached to a sqldatasource :
SELECT [fldBaseline] FROM [BI_PATHS_Target_Baseline] WHERE fldBranch = @fldBranch and fldyear=@fldyear and fldcategory = @cat
and i want to make a LABEL to read that fldbaseline value and i tried this :
[Code]....
btw the @fldbranch is pulling from a dropdownlist and so it the @year but the @cat is just defined always as 'LEAN' But im not sure what to put inside the select() part. i know you have to put atasourceselectarguments.empty if no parameters, but what would I do here since their are 3?
I have just used the Import and Export Wizard to copy my production SQL Server database, which uses Membership and Roles. I used the option to copy all the data from existing tables and views and did not modify the mapping in any way. Things do not seem to have gone well.....
My source database has a bunch of views with names like vw_aspnet_Applications,vw_aspnet_MembershipUsers, etc. The copy database has these listed as tables!I wondered if running aspnet_regsql.exe might fix things. I needed to run this anyway to create all the missing stored procedures for Membership, etc. However, it failed with the error:Setup failed.Exception:An error occurred during the execution of the SQL file 'InstallCommon.sql'. The SQL error number is 2714 and the SqlException message is: There is already an object named 'vw_aspnet_Applications' in the database.Creating the vw_aspnet_Applications view...I am a bit lost. All I want to do is to create a total clone of my production database for test purposes. Where do I go from here?
I need a submit form in my site and tried to use this code to create one. It works on one of my sites but won't on this one (see the problem at [URL] I am posting my code below that goes with the page published at the above URL. Can anyone tell me why it displays the way it does instead of as a submit form?
Scenario: I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is: I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I'm implementing an AJAX autocomplete feature where the user types into a textbox and the webpage generates suggestions (pretty much like how Google's search box works). I got the AJAX part to work right, but for some reason, my database query does not.Let's say I want to find "Chicago". Using the following query does not find it.SELECT TOP 10 citynames FROM city WHERE CONTAINS(citynames, 'chi*')But using this query does.SELECT TOP 10 citynames FROM city WHERE CONTAINS(citynames, 'chicago')By the way, "citynames" is an ntext type field and I'm using SQL SERVER 2008.Does anyone know why my first query can't find "Chicago"? I've been staring at that query for hours, yet can't find anything wrong with it. Something wrong with the database maybe?
I got a textbox in my form and I want to when a user start typing in the textbox the listbox below the textbox will select the item that starts with that string
for example, it i type I
than in myserver side code will call that SearchString method which will go through that listbox and do the rest...
The database I am using has a schema called EQB and as such, my stored procedures are named as EQB.usp_SelectFunds, EQB.usp_SelectAccount, etc.
On the select tab of the Configure Data Source screen, I choose to use a stored procedure. The dropdown shows my stored procedures, however, the schema name does not show up in front of the stored procedures in the drop down. I see only usp_SelectFunds, usp_SelectAccount, etc.
I select one of the stored procedures and when I click TEST, I get the message that the stored procedure is not found. If I instead choose to use a SQL statement instead on the configuration screen and enter EXEC EQB.usp_SelectFunds and click TEST, it works fine.
Why are my stored procedures not showing up correctly in the stored procedure drop down and how can I fix this?
I'm concatenating a string in codebehind to use in a sql select statement.
in aspx
<asp:Label ID="LabelHidden" runat="server" Visible="False"></asp:Label> SelectCommand="SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)" <SelectParameters> <asp:ControlParameter ControlID="DropDownList_Employees" Name="ID" PropertyName="SelectedValue" Type="Int32" /> <asp:ControlParameter ControlID="LabelHidden" Name="ActivityName" Type="String" /> </SelectParameters> in codebehind foreach (ListItem li in ListBox_Activities.Items) { if (li.Selected) { queryBuilder += li + "', "; } queryBuilder = queryBuilder.Substring(0, queryBuilder.Length - 1); LabelHidden.Text = queryBuilder;
When i run the code it comes up blank. I did a query trace and it seems to be running as
exec sp_executesql N'SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)',N'@EmployeeID int,@ActivityName nvarchar(50)',@EmployeeID=4,@ActivityName=N'Production Technical Support'', Tools Development'','
with exta "'s
How can i format the queryBuilder string correctly in my code?
I am writing a simple form that will take in data and insert it into a db if it's a new record and update the existing record if it already exists. The insert works fine, but the update isn't working at all, yet the code looks solid to me and everything I've compared it to in my google searches.
I have stepped through this code to test it and I am puzzled as to why the update isn't going through to the DB. When I run the SQL statement in SQL editor it updates fine. All variables are getting the proper values when I step through.
I am sure I am not the first to ask this question but I cannot find an answer in these or any other forums. I guess I am not wording the question right. In short I have a gridview populated but a database via an SQLDatasource. I have an Edit column in the datagrid and an updatequery in the datasource. When the Edit is click the line goes into edit mode, the user then clicks Update and I get an error. Could not find control 'DropDownList1' in ControlParameter 'Frequency'. The only complication is that there is a drop down control when the "EDIT" column is selected. The dropdownlist gets it list from another SQLDatasource. This all works fine. Here is the code snip:
I have detailsview with a SQLDataSource to 1 table (City) and am referencing another table (Unit) for one if it's fields.
[code]....
I changed the Unit Code (City Table) field into a template field and am using a dropdownlist item to reference the Unit Name from the (Unit Table) with the CityTable.Unit Code = UnitTable.Unit Code. However when I go into the update and change the dropdownlist item to another Unit Name it is keeping the original Unit Code value or it might even be selecting the first value from the dropdownlist item.
