Update Command In Vb.net
Mar 21, 2011
My program is doing good when I suddenly bumped into this problem. I dont know how to do the next functionality that I need to accomplish. I am done with inserting values, showing the gridview etc and it works great. Now my problem is the update command.
I have 2 tables
table: tblDest
Fields:
destLastName
destFname
destEmail
Table:tblSource
Fields:
Sourcelastname
SourceFname
SourceEmai
Now, when I run my update command in sql server, it works great! I just right click the database, click new query and i run this command:
Code:
update tblDest set DestEmail =(Select SourceEmail from tblSource where tblSource.SourceFname = tblDest.DestFname and tblSource.SourceLastname = tblDest.DestLastname)
what the query does, is it updates the table tbldest email where lastname and firstname exists in both tables that are equal,
the question is, I want to automate this, I am done with inserting values, the problem is, I dont know how to run the update command,
I tried doing this:
Code:
Dim sqlds As New SqlDataSource
sqlds.ConnectionString = ConfigurationManager.ConnectionStrings("sqlconnect").ConnectionString
sqlds.ProviderName = ConfigurationManager.ConnectionStrings("sqlconnect").ProviderName
sqlds.UpdateCommand = "update tblDest set DestEmail =(Select SourceEmail from tblSource where tblSource.SourceFname = tblDest.DestFname and tblSource.SourceLastname = tblDest.DestLastname)"
DestGrid.DataSource = sqlds
DestGrid.DataBind()
but nothing happened.

how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...

I've recently started working in ASP.NET and RDBMS.I'm making a test form where I can do basic add,update,delete operations.I'm using OracleDataClient to do the DB operations.I was able to populate a listbox using OracleDataAdapter.
Now after clicking on update button,I intend to Update in DB.I've Dataadapter with it's update property.But the update query is not happening.The examples I saw over net all have Select command before Update.Is it actually like that or am I missing some point.
How does Oracle DataClient work with Insert,Update,Delete Commands.

I have a page that binds data from DB to a DetailsView.I want to use the auto-generated Update command.
Everything went OK, and also updating was successful, but if I remove any field that I don't want to have chance to update, then the Update command doesn't update! the old values retain!
I mean: if all of the fields are present in the detailsView, the update will be OK, otherwise, the update will NOT update any thing.I've tried to mark the fields that I don't want to view as "Visible = 'false'" but with no good results!

I have a detailsview which I am populating using a SQLDATASOURCE, which is bound to a table in a SQL db. Because the number of columns in the table will change, I am using SELECT * from [TABLENAME] to populate the view, this works fine.
My problem is that I need to also be able to update the table and I thought the best way was to generate the updatecommand in the code behind. This is no problem, code is as follows:
[Code]....
But the next stage is to create the relevant parameters for the update command. Does anybody have any thoughts on this? All of the information I have found for the updateParamater reference knowing the final value.
What I really need to do is the code behind equivalent of
<asp:Parameter Name="PARAMETERNAME" Type="Int32" />
Not sure whether this is possible.

Code:
SqlDataAdapter da = new SqlDataAdapter("select * from " + txtTableName.Text, DataStoreGeneral.GetConnectionString());
DataTable dt_app = new DataTable();
da.MissingSchemaAction = MissingSchemaAction.AddWithKey;
da.FillSchema(dt_app, SchemaType.Source);
da.Fill(dt_app);
SqlCommandBuilder build = new SqlCommandBuilder(da);
da.InsertCommand= build.GetUpdateCommand();
da.Update(ds.Tables[1].GetChanges(DataRowState.Added));
Problem: In my scenerio i had dataset with a table (in code->ds.Tables[1]) in rowstate added. I wanted update on database with this table so i changed insert command of adapter to update command of command builder, but no update got performed. When debugged in sql profiler i found that update command generated by builder is checking all columns in where clause and with parameter value of data table instead of from database column value.
exec sp_executesql N'UPDATE [ShopResources] SET [GROUP_RESOURCE_ID] = @p1, [SEQ_NO] = @p2, [SUB_RESOURCE_ID] = @p3, [EFFICIENCY_FACTOR] = @p4, [RUN_COST_PER_HR] = @p5, [RUN_COST_PER_UNIT] = @p6, [BUR_PER_HR_SETUP] = @p7, [BUR_PER_HR_RUN] = @p8, [BUR_PERCENT_SETUP]
= @p9, [BUR_PERCENT_RUN] = @p10, [BUR_PER_OPERATION] = @p11 WHERE (([GROUP_RESOURCE_ID] = @p12) AND ([SEQ_NO] = @p13) AND ([SUB_RESOURCE_ID] = @p14) AND ((@p15 = 1 AND [EFFICIENCY_FACTOR] IS NULL) OR ([EFFICIENCY_FACTOR] = @p16)) AND ([RUN_COST_PER_HR] = @p17)
AND ([RUN_COST_PER_UNIT] = @p18) AND ([BUR_PER_HR_SETUP] = @p19)
The problem I identified is parameter values inside where clause are from data table which is obvious that update condition will not be met. Is there some way to restrict where clause to primary key only in Command Builder?Or why is command builder taking where clause parameter values from datatable instead of command (query)?

I have a GridView that is populated from a LinqDataSource. When I update a row, the RowCommand fires and the change is persisted to the database, but the Grid does not refresh. I have it in an UpdatePanel and explicitely call Update() in the RowCommand handler, but there is no postback and the page just sits there in Edit mode. Once I click cancel, it will return to view-only and the grid shows the new value.
something in the wiring of the GridView regarding the data source is wrong. No exception bubbles up, though. A stripped-down copy of the markup is below.

I am trying to use an Update Command within my GridView. I need to find the "FindControl" for the Edit Command textboxes.
Ie. When the user clicks the Edit button, the row is populated with dropdown boxes, textboxes, etc for editting. Then when the user clicks on Update (button) and the GridView1_RowCommand function is activated with 'if (e.CommandName == "Update")' statement with my FindControl. etc. and my sql UPDATE command statements are used. How do I convert my FooterRow info to my Edit FINDCONTROL info?

Is it possible to perform an update command which performs addition using a value from a textbox? For example: User inputs a number into TextBox1 (I use regular expression validation to ensure this is an integer).

Basically if the user inputs 5 into TextBox1, I want the update command to subtract 5 from that user's ballance.

I'm trying to create a ShoutBox for my site, and for those of you who are not familiar with shoutboxes, they are chat boxes on websites that users can post live messages on, and the other uses will see their message and be able to respond. I didn't find any good ones online, so I started to write my own. I'm doing it with an XML, but I want the user to be able to post messages using a textbox I added (txtMessage) and the button (cmdPostMessage), which should add a new item to the XML file, and all the other uses will receive that message (their xmlDataSource and the DataList will PostBack every second or something like that). It is able to read messages, but not send.I am however facing three problems:
1- I need to find a way for the user's input to be added to the XML.
2- I need to find a way for the current logged-in username to be found, and added to the XML, and also detect if no user is logged in, in which case the user wil receive an alert saying "Please log in to post messages to the ShoutBox" and redirect them to the login page.
Here is the text in the XML

I have 3 gridviews in one of my web page. I have simplified the system structure in the image below(further description will be stated below the image): As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews. During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
The data in the returned datatable will be filetered by type using RowFilter method and stored into the 3 dataviews. Each dataview will act as the datasource for the 3 GridViews respectively, and therefore I specified the datasource programatically instead of setting the datasourceid for each gridview.
dataview1 = New DataView(dtSelectedTable)
dataview1.RowFilter = "Type='1'"
GridView1.DataSource = dataview1
GridView1.DataBind()
dataview2 = New DataView(dtSelectedTable)
dataview2.RowFilter = "Type='2'"
GridView2.DataSource = dataview2
GridView2.DataBind()
dataview3 = New DataView(dtSelectedTable)
dataview3.RowFilter = "Type='3'"
GridView2.DataSource = dataview3
GridView2.DataBind()
However, the Update(command button) and Delete(template field) doesn't work, the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource. I couldn't figure out why, hope that someone who have come across the same problem couldn't provide some guidance.

I have a asp.net gridview control on my page with several fields and a couple of command fields. However, the update command is giving me problems.
Here is what works. The update command works provided I put straight text into the textboxes that appear. I even have one field that contains a dropdown list which works fine.
Here's the problem. I have two fields that need to access their value programmatically. These fields will reflect the current datetime and the current loggedin user from active directory. I have already created public strings in the C# code.
When I run the edit command on the asp form the grid uses one "DataKeyNames" element. With this the grid can update the selectedrow. However, I haven't been able to access it programmatically in the C# code. I can access the selectedrow in the "selectedindexchanged" event but then I am not able to update my fields in the gridview itself. So, part one of my question is how to I access the "DataKeyNames" properties of a gridview control.
if I can't access the "DataKeyName" property perhaps I could set the label nested within the gridview to the "myCurrentUser()" public string. I am inserting my code to hopefully make this clearer.

I've got a simple detailsview on a webpage for viewing, adding, and updating inspectors. Since it is a simple details view I'm just used the datasource select, update, delete, and insert commands. When I debug the page it populates the detailsview appropriately and allows me to page through the inspectors but when I try to update a field I'm getting the implicit conversion error in the attached doc. Below is my detail view markup. I was thinking the error is caused by the checkbox type being boolean while the SQL type for "Active" is bit but I've tried to use various conversion methods and can't seem to get them to work.
Code:
<asp:DetailsView ID="dvInspectors" runat="server" AllowPaging="True"
AutoGenerateRows="False" DataKeyNames="InsID" DataSourceID="InspectInfo"
Height="50px" Width="212px">
<Fields>
<asp:TemplateField HeaderText="Insp ID" InsertVisible="False"
SortExpression="InsID">
