Data Controls :: Error In Update In GridView

Feb 20, 2013

When I press in a button "Update", I find this error:

"objectdatasource could not find a non-generic method 'update' that has parameters:

ID_MODULE, NAME_COMPONENT, DESCRIPTION_COMPONENT, TYPE_COMPONENT, CODE_COMPONENT, ID_COMPONENT, NAME_COMPONENT_1, TYPE_COMPONENT_1, DESCRIPTION_COMPONENT_2."

And the code of my gridview in this page is:

<fieldset> <legend>Module <asp:Label ID="moduleNameLabel" runat="server"></asp:Label> components list</legend> <br /> <div class="scroller_rem_boq"> <asp:GridView ID="GridviewComponent" runat="server" DataKeyNames="ID_COMPONENT" AllowSorting="True" AutoGenerateColumns="False" PageSize="5"

[Code] ....

The update methode in "cwt_package.Component" is 

public void Update(string ID_MODULE,string NAME_COMPONENT,string DESCRIPTION_COMPONENT,string TYPE_COMPONENT,string CODE_COMPONENT,string ID_COMPONENT) {try
{DataTable moduleComponenents;moduleComponenents = this.existsComponentInModule(ID_COMPONENT, CODE_COMPONENT, ID_MODULE);
if (moduleComponenents.Rows.Count == 0){ OracleConnection chaine = cwt_package.connexion.connectString();

[Code] .... 

The package  "pa_component.modifier" is:

"
PROCEDURE modifier( idComp COMPONENT.ID_COMPONENT%TYPE, codeComp COMPONENT.CODE_COMPONENT%TYPE, idMod COMPONENT.ID_MODULE%TYPE, nameComp COMPONENT.NAME_COMPONENT_1%TYPE, descr COMPONENT.DESCRIPTION_COMPONENT_2%TYPE, typ COMPONENT.TYPE_COMPONENT_1%TYPE ) IS
CURSOR cur_inputOutput( p_idModule COMPONENT.ID_MODULE%TYPE, p_idComponent

[Code] ....

The table Component contains this columns :

"ID_COMPONENT,ID_MODULE,NAME_COMPONENT_1,DESCRIPTION_COMPONENT_2
,TYPE_COMPONENT_1,CODE_COMPONENT"

Where is the error ????

Forms Data Controls :: Gridview - Update Statement Error?

Apr 29, 2010

I'm quite new to asp.net. I use MS Visual Studio 2008 and MySQL database. When I try to edit a record via gridview and the generated UPDATE syntax I get an error.I inserted a gridview into my asp.net web application and connected it to my database (all is OK). Then I checked for auto generation of update and other syntax:

[Code]....

When I test in a browser I get a pop window form for editing a record. But when I click "update" I get the following error:"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?, strSkrajsanNaziv = ?, strKraj = ?, strDavcnaSt = ?, SkupinaID = ? WHERE Stran' at line 1"what's wrong with the UPDATE syntax? Is this syntax only valid when using MSSQL?

Forms Data Controls :: Loop Gridview To Update Values In Gridview To Stored Procedure?

Jan 14, 2010

I would like to ask a question on the visual basic codes to loop the gridview to retrieve the values and based on the values, it will be provided as parameters to update to the database table using stored procedure.

Firstly, I have a gridview named grvProduct. The page (ui) will be loaded with data from the database with the use of stored procedures. And only certain values can be edited through the use of template in gridview. So based on those edited values, I'm supposed to pass these values as parameters to the stored procedure which will then update a database table.

Let say, I have 3 records retrieved from the database and displayed in the gridview. And I would like to edit a values in the 3 records, how do I do batch update and pass those parameters to the stored procedure? I went to debug and step through the visual basic codes and realised there were too many arguments specified because I actually loop the gridview.

Below is my visual basic codes:

[Code]....

Below is my Stored Procedure code:
[Code]....

I believe it is the error in the looping of the gridview which results that I could not batch update the data/values.

Data Controls :: Making GridView Open In New Page Update Changes Made In TreeView Gridview At Runtime

Mar 26, 2016

Query 1 - Grid View: - I have an excel sheet which I import into gridview at runtime. For excel sheet import, I have a fileupload dialog box and an asp.net button control which when clicked imports the sheet contents into a gridview. The problem is I have my fileupload box and button control in a page called Default.aspx and I need the gridview get displayed maximized in a new page called Default2.aspx.

Also, I need to specify the row number of the field titles from the excel sheet dynamically at runtime so that the gridview appends any new field/column from that row on. The excel sheets I use contain complex formatting. Is there anyway to display the excelsheet contents as they have been defined and formatted?

Query 2 - Sessions: - I add nodes to my treeview dynamically at runtime. Since HTTP is a stateless protocol, the changes which I do remain only for that session. How do I append the changes I do to the treeview simultaneously in the code?

- I have appended 2 extra columns into the excel sheet generated gridview which take input through dropdownlistbox control at runtime. How do I update and retain those changes in the gridview?

Forms Data Controls :: .NET 3.5 FormView With User Entered Primary Key Update Error?

Aug 9, 2010

I'm trying to create a Formview in ASP.net 3.5. The underlying SQL Server table does not have an identity field based Primary Key. The primary key is a 4 character user entered field. I have created the form and all looks good but I get the following error message when I try to insert a record

Could not find a row that matches the given keys in the original values stored in ViewState. Ensure that the 'keys' dictionary contains unique key values that correspond to a row returned from the previous Select operation.

I thought ViewState was supposed to resolve the issue. I have viewstate enabled on the page and the formview but that doesn't seem to make a difference.

How can I create a form view with a user-entered text field as the primary key and get the b.... thing to work?
