DataSource Controls :: Updating Database With Gridview Control
Nov 30, 2010I 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:
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateEditButton="True"
Forms Data Controls :: Updating The Datasource / Mark All The Values In The Binding Column Of Datasource If Checkbox In Headertemplate Is Checked?
Sep 29, 2010Scenario:
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.
DataSource Controls :: SQL UPDATE Statement Not Updating DB?
Feb 24, 2010I 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.

DataSource Controls :: Relational Field Not Updating On Update?
Mar 1, 2010I 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.
DataSource Controls :: Updating Dataset Value To Upper Or Other Method?
Jan 13, 2010I have a dataset where I would like to upper all string fileds and when done check each field for a value. The other way i thought to do it is to do an upper of each string when I do the conditional check. I would like to know what is quicker upper of the values in the dataset or upper in the conditional statement? Knowing the dataset will contain a max of 10.000 rows and there are multiple conditional statements in the complete process.

DataSource Controls :: Querying & Updating Data From Dataset?
Mar 15, 2010I'm hoping someone can point me in the right direction. I will be as detailed as I can in explaining the issue;I have a dataset I have instantiated in a class file (vb.net), and fill the data succesfully. That data is then dumped into an excel file. What I need to do is to go through all the data in the dataset, and directly update the database, changing a "status" column from "pending" to "processing" based on the store number. As I am new to datasets (relatively speaking, of course), I am not quite certain how to accomplish this task. Below is the code I have so far:

If anyone could provide sample code to use, or could provide a quick bit of code I could just copy and paste in and test,
DataSource Controls :: Prepopulated Form Not Updating Correctly?
Apr 28, 2010I'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.
DataSource Controls :: Updating A Newly Inserted Row In A Tableadapter?
May 7, 2010I need to insert two rows into a tableadapter - and then take the identity column from each row and update them into a column on each row.
My problem is that I cannot update a column on a newly inserted row. Stepping through the code seems to indicate that I have updated the column, but when I check the database - the column indicates null.
I have tried calling Update on the TableAdapter, then performing the update on the column, and then calling Update again, but the update still isn't taking.
DataSource Controls :: Updating A Listbox With Updated Parameters?

Forms Data Controls :: Updating Database In ListView1_ItemCommand?
Jul 22, 2010I have a page where I want to let the users vote on displayed items. My customer wants this done with an image and a VOTE FOR THIS link. The link and image are to disappear once the user has voted, and be replaced with the number of votes for that item. I've made the VOTE FOR THIS link a link button. I'm have two problems:
1) the ListView1_ItemCommand code is always excecuted twice, so the vote count is being incremented by two, not one each time someone votes.
2) A page refresh causes the ListView1_ItemCommand code to run (twice) so a page refresh also casts two votes for the item
If it makes a difference, I display one item per page.

View 6 RepliesDataSource Controls :: Updating SQL Data Fields By Field Index?
Jan 7, 2010I have a situation where I have a file with each Account Record contains Monthly Expense Total Fields and Monthly Budget Fields for 2009, 2008 and 2007. I'm working with 72 fields (36 Expense and 36 Budget).
Need to create New Year Proceure that will shift data from 2008 to 2007, 2009 to 2008 and move Zeros to 2009 for both Expenses and Budgets.
I can do this using Parameters and Update SQL but I am under the impression that I must specificaly name each field in defining Parameters and SQL Update Command.
Since all fields are sequential withing a record, is there a way that I can use a For/Next loop to index my way through the fields moving data from one year to another?
When using DataReader I'm able to use reader.item(index) to access data record fields.
DataSource Controls :: Adding Rows And Updating Tables From Datatable
Mar 7, 2010Maybe this could be a simple questino, but for me it's difficult to do this action: I have a table in sql server 2005 with some records stored, for example 10 records. The primary key of this table, let's call it "Employee", it's a number field with an autoincrement constraint. I want to store more data into the table by using a OdbcDataTable object and OdbcDataAdapter and adding new rows to the datatable and afeter that use the "Update" method from the OdbcDataAdapter object.
The big deal is this: let's suppose that I want a add a new record to the datatable object, using any method or code sequence that you want. if I have 10 records stored on the data base table, when I retrieve this table schema by using the OdbcDataAdapter "Fill" method, I have a copy of the data base table schema in the DataTable object, right?. if I add a new row on the datatable object, it's suppose that the primary key column of that table must AUTO-INCREMENT the value of the key, I mean if the last value that I store on the table was the number 10 on the PK field, when I add a new row on the datatable object, the PK value on the datatable object must be the number 11 if the autoincrement constraint is present into the DataTable object, but in my case, it doesn't work
So, How can I define the conditions or set the c# data objects properties to wor in that way???. In this moment the PK column on the odbcDataTable doesn't auto-increment its value when I add a new row on it.
Please helpe with this.
PD: I have another question about the DataTable object, how many records can store this object?? I have some problems with this because sometimes when I use the Fill() method to get data into the DataTable or a DataSet object there's no problem if the Fill() method retrieves about 142000 records, but when I retrieve over the 145000 records, when I inspect the DataSet or DataTable object by using the debuging mode, they have null value. Any of you can tell me why this situation ocurrs??
