Getting SQLDataSource Update Paramater From Gridview?
Mar 28, 2011
I am trying to get a parameter for my update from the gridview but it is an ID column that I do not want displayed. If I display the data in a boundfield it works fine but if I set the visibility to false the parameter is no longer sent to the update stored procedure. There does not appear to be a hiddenfield column that I can put into the gridview.I have tried to set the parameters through the code behind but I am not certain on how to access the data I want the following code does not work (It sets the parameter to nothing
Protected Sub grvFacilityDisciplineBillingRate_RowUpdating(ByVal sender As Object, ByVal e As GridViewUpdateEventArgs) Handles grvFacilityDisciplineBillingRate.RowUpdating
Dim row As GridViewRow = grvFacilityDisciplineBillingRate.Rows(e.RowIndex)[code]...
And this is the front end with the two ID columns displayed, which is not what I want
i couldnt find a specific answer to this question, i am relatively new to .net :)
i have a gridview that is displaying data from a sqldatasource in my page_load event. i need to loop through the records and update each value of a particular column BEFORE being set into the GridView.
i have tried converting to a data set and looping through updating the values, however it seems that one i initially run my query the values get set right into the GridView and i can't update them after that.
Do I need to add one of the GridView functions like Databound and do the loop in there?
I have two image buttons in a gridview, one to approve the opening of the record and one to approve the closing of the record. I have added a CommandName to each button (OpenApproved and CloseApproved) and in the grids rowcommand I would like to update the database with the Username of the person clicking the button, Username goes into either the OpenLeadApprover or CloseLeadApprover field depending on which button is pressed. The grid has a sqldatasource with an Update stored procedure which has three parameters, @WorkOrderIDWhat I have tried to do in the RoeCommand event is declare a variable for the sqldatasource and add the parameter value to it, then run the update command. Here is the code:
I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in my case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.
My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??
If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..
My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List?
Which one is better, I mean ObjectDataSource or SQLDataSource or my XML method?
If I want to access the method in which we define update query, how can I access that method on aspx page & update the data in a grid view without direct use of an query on aspx page under sql data source?
i want to pass multidementional array as parameter, below the code i worked, is it right
class ASRateContract { public string[,] standardrate = new string[3,2]; public string[,] storagerate = new string[3,3]; public void setstandardrate( string [3,2]name ) { standardrate = name; } public string setstoragerate() { return ""; } public string getstandardrate() { return standardrate; }
I have a list of paramaters eg A,P,C,K,L each paramater represent a value in the database when past in via request.querystring it returns the value from the database. the problem i am having lets say we http://localhost/default.aspx?string=P when you look at the view source of the page its changing the parameter "P" to another parameter from the list. i have approxmately 6000 clients connecting to this default page with different paramater based on their location.
I am trying to implement admin login and operators(india,australia,america) login, now operator id starts with 'IND123' 'AUS123' and 'AM123'
when operator india logs in he can see the details of only members have id 'IND%', the same applies for an australian and american users
and when admin logs in he can see details of members with id 'IND%' or 'AUS%' or 'AM%'
i have a table which defines the role i.e admin or operator and their prefix(IND,AUS respectively)
In loginpage i created a session for Role and prefix
PREFIX = myReader["Prefix"].ToString(); Session["LoginRole"] = myReader["Role"].ToString(); Session["LoginPrefix"] = String.Concat(PREFIX + "%"); works fine
In main page(after login) i have to count the number of member so i wrote
string prefix = Session["LoginPrefix"].ToString(); string role = Session["LoginRole"].ToString(); if (role.Equals("ADMIN")) StrMemberId = "select count(*) from MemberList"; else StrMemberId = "select count(*) from MemberList where MemberID like '"+prefix+"'";
Problem: 1. i want to constructor parameter something like
StrMemberId = "select count(*) from MemberList where MemberID like '@prefix+'"; myCommd.Parameters.AddWithValue("@prefix", prefix);
Which is not working
2 Displaying the members in gridview i need to give condition (something like if (role.Equals("ADMIN")) show all members else show member depending on the operator prefix)the list of members in operator mode and admin mode. - where to put the condition in gridview how to apply these
i am using a gridview which shows the data and a select column. when the user selects a record a detailsview is shown with the respective details and an edit button inside it. when the user clicks on the edit button the entire detailsview becomes editable and the user can now edit the selected record .here the problem starts cause when the user clicks on the update button there is an error stating that illegal variable/number or parameter not found.i am using sqldatasource to bind the gridview and detailsview with an unique RequestId fieldwhich detailsview sql datasource uses to bind the record uniquely.
I got the viewCustomer.aspx page sending parameter to EditBusiness.aspx page as per below coding .
After that i retrieved to EditBusiness.aspx.cs by using (Request.QueryString["customerId"] ) and save in session . Then i tried to use the session in the EditPersonal.aspx and EditOther.aspx is worked but then back to EditBusiness.aspx the customerId parameter is disappeared . I believe is because in EditBusiness.aspx.cs using string customerId = Request.QueryString["customerId"] . Even I have tried cookies but its doesnt work .
I have a FormView which is bound to an SQLDataSource. When a user clicks on a save button the form, I need to write any changes made to the FormView back to the table.
I have a Stored Procedure on my MSSQL 2005 database that should be executed when the user clicks on the save button.
It appears the Update is firing, but when I trap the DbCommand object in the SQLDataSource's 'Updating' event, all of the parameters that should be passed to the Stored Procedure are coming through as NULLs. Consequently, the Stored Procedure isn't updating anything.
In the click event of the save button I'm explicitly firing the SQLDataSource's Update method:
[Code]....
The parameters in the SQLDataSource <UpdateParameters></UpdateParameters> section appear to be correct.
Can anyone give me an idea on what to investigate to figure out why it appears the Update is only picking up NULLs?
I've already spent hours in searching through the forum to be able to do the following:I have a SQL datasource defined with a checkbox in it. Purpose is to update one column (userid) behind the table for only that row when the checkbox is selected.This is the code I'm currently having:
I am building a web site, it's used to manage the data in SQL server so the another web site(connect to the same SQL database) can receive the new infoSo far I've build 2 parts, one manages the news system, the another manages the album system, news manage system work perfect, when I update, add or delete news form the web site (using sqldatasource, INSERT, DELETE and UPDATE command), the data inside SQL changes as well.
I have a gridview that is using a SQLdataSource with an update statement and I am able to print out the update statement listed in the SQLDataSource by doing this:
[Code]....
but for some reason the record is not being updated so I want to know how do I print out the entire Update statement, including the value of the EmailAddressID to make certain that the update statement is being set correctly?
I can test the update statement above manually, taking the EmailAddressID for that record and then run the update statement manually using SQL Server Mgmt then it updates the record correctly so I know the update statement set in the SQLDataSource is ok. However I still want to print out the update statement that is supposed to be executed in the vb code, how to do this?
I see there is an event called "SqlDataSource1_Updating",
is it possible to print out the actual update statement there?
Just to be clear in the asp.net page I want to do something to print out the actual full update statement, ex:
<SQL> UPDATE [EmailTable] SET [EmailAddress] = @EmailAddress WHERE [EmailAddressID] = 22 </SQL>
I'm trying to update items in my SQL database from a ListView. It works, but all entries in the database update. Not just the one I'm working on. I backed up the database prior to testing, so there's not any issues there.This is how my SqlDataSource UPDATE command is setup:
SQL Code: UPDATE entries SET duration = @duration, checkinDate = @checkinDate, receivedBy = @receivedBy, cosmeticDmgIn = @cosmeticDmgIn, STATUS = N'closed'
I don't have any code setup to update the database, which is probably the issue.When I load the ListView, select edit, type in my edits, and click "Update", all the rows in my database, for that column, are updated with that data.I tried inserting the parameters manually, within the ItemUpdating event, but it never works.
I've got a request to redesign the web application to allow support for up to 3 users (before there was data only for one people on page). Since I don't want to build entire page again I wonder how is possible to replace value which is for example:
[Code]....
with value retrieved from querystring?
Users are displayed on page in row: querystring value ID(for example 123), QS value ID2(for example 231), QS value ID3(for example 343).
Users are all stored in one row of the same table. If second user is selected then value of his/her should be taken as value of ID.
I'm using quite a lot <%# Eval ("ID")%> on my page and I don't want to replace it with some object but just overwrite it's value according to querystrings values.
I hope this doesn't sound too complicated as the real problem is fairly easy but don't have ideas how to deal with it. I've thought I can put to replace the value retrieved from SP but I can only change parameters. And ID is not select parameter.
One:Table Name Rider With columns RiderID,LName,City
Two:Table Name Car With columns CarID,RiderID,Color
What I would like to be able to do is to allow the users to do an UPDATE on both tables.
Like if you crreated a SQLDataSource using just one table as it's source. You can use that SQLDataSource for a gridview.
Then in the gridview you can display all the data from the table but you can also EDIT all the data in the table through the gridview.
But if I create a SQLDataSource using 2 table joining them together with an INNER JOIN with a Primary Key in one table and a Foriegn Key in the other table. I can still use this SQLDataSource with a GridView to display the data but I can't EDIT the data through the gridview for the 2 tables.
Is there anyway to do this using a SQLDataSource and GridView?
