VS 2008 DeleteCommand Error With Gridview Sqldatasource?
Oct 2, 2010
I typically don't use the sqldatasource control but trying it out and can't seem to get the delete function working. It doesn't seem to be passing a parameter to my stored procedure. The error I get is: Procedure or function 'sp_DeleteCraigsListEntry' expects parameter '@craigslist_search_id', which was not supplied. Any thoughts?
How to write a delete query which can delete a specific row from grid view? I wrote this :
DeleteCommand="DELETE FROM member" It delete all my entry in table called member. =( <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FYPConnectionString %>" SelectCommand="SELECT * FROM [member]" DeleteCommand="DELETE FROM member"></asp:SqlDataSource>
I use the sqldatasource control a lot with stored procedures. But this time I'm using some code I found online where I am defining the new sqldatasource in the code and using it. You can see this below. I am getting a NullReferenceException on the first SelectParameters line and not sure why. Do I need to add the parameters different?
Code: Dim SqlDataSource As New System.Web.UI.WebControls.SqlDataSource() SqlDataSource.ConnectionString = ConnectionString SqlDataSource.SelectCommand = "MySprocName" SqlDataSource.SelectCommandType = SqlDataSourceCommandType.StoredProcedure SqlDataSource.SelectParameters("Distance").DefaultValue = 25 SqlDataSource.SelectParameters("ZipCode").DefaultValue = "31410" Dim arg As New DataSourceSelectArguments() Dim dv As System.Data.DataView = DirectCast(SqlDataSource.[Select](arg), System.Data.DataView)
When the data is retrieved through a stored procedure using the SQLDatasource control that is binded to a gridview control, I want to change some data that is in some of the columns. Can i do this in one of the events either in the gridview or data control? I know you can do some formatting on the aspx page side such as dates, etc. but was wondering if I can do it on the vb code side?
I'd like to delete the row without using the DeleteCommand in GridView. I created the button "Obrisi" which should delete the row from the table, but when I click on it I get the following error: "The multi-part identifier "System.Web.UI.WebControls.DataControlFieldCell" could not be bound." and I don't understand what the problem is.
Here is the code (part of the code after else if is important):
I am not able to figure out why I am getting the null error at SqlDataSource10.Insert(); I tried running through break points and i checked the Insert statement and it has all the required values .. but I get error saying it cannot insert null into NrNarrativeDays. I am working off a sample at this link..
For some reason the select parameter pAddId is getting set to null and get the following error when the content page is loaded If I hard code the value it works RA-01036: illegal variable name/number Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: Oracle.DataAccess.Client.OracleException: ORA-01036: illegal variable name/number
I have a datasource that is connected to a stored procedure and I need to do a postback on the web page but do not want the sqldatasource to do a databind. What I am doing is when I change a dropdown box to fill in some textboxes with specific dates, I do this on a postback so the textboxes are filled in with the dates. But the SQLDatasource control data binds again and shows new results in my gridview.
Is there any way to prevent this so I can just postback to fill in the textboxes?
I have a list of numbers I need to submit one at a time to a stored procedure to add to a table. I don't know any other way around this. The database for this is an AS400 so it's not like using mssql server. I have a connection string and use the SQLDatasource controls to select data because I can select a stored procedure with it to call. Now I need to do an update and if it was just one time of submitting information I would do it the same way. But I need to submit each number till I do them all. How can I do this? Do I still use a sqldatasource control and set the value to be pulled from like a session var and just loop through setting the session and then sqlds.databind over and over? I added a DBML but can't do that with the as400 stored procedures as far as adding them like I do mssql.
I have grid which displays users information. I have commandColumn with edit, delete commands. Delete means change users status to archive. What I want is to have delete button in rows with users with status active and restore button (it may be only change in text) in rows with users with status archive.
I've been working on this error all day! I have a dataview created from a sqldatasource control and I'm trying to assign it to a gridview but I get Object reference not set to an instance of an object. Code: Try Session("dsCustomer") = "Y" [code]......
Can't I assign a dataview as a datasource? Or not?
On my web pages I display the data as mm/dd/yyyy and that is how the user will enter the dates as well. But when I pass the textbox control that has the date in it as a parameter to the SQLDataSource control, I need it to be sent in the YYYY-MM-DD format for the AS400. Is there a way it can be changed in between?
I have a sqldatasource control that I want to get the field values from as it is selecting. Is there any way to do this in the dsControl_Selecting event for each record without binding it to any control or formview? I would like to call dsControl.DataBind and retrieve the field values.
I have a simple gridview control. It has edit and cancel buttons for each row. User's can click on edit column and edit a row and click on save to save the record.
When the user clicks on save we get the error: ORA-01008: not all variables bound
User is allowed to edit only 3 fields and rest of the fields are only readonly. For those editable three fields, I am using EditItemTemplate. ASP.net doesn't throw any errors for the first two edititemtemplates. The problem comes only with the third field which is "BSIS Type". I tried to figure out almost 5 hours and don't know what to do.
This the code I have:
HTML Code: <asp:GridView ID="GridViewActualsMapping" runat="server" HeaderStyle-BackColor="#444444" HeaderStyle-ForeColor="White" Font-Size="10pt" Cellpadding="4" AutoGenerateColumns="False"
[code]....
Error is:
HTML Code:
ORA-01008: not all variables bound
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.OracleClient.OracleException: ORA-01008: not all variables bound
I have datalist bind with sql datasourceI have update command
Protected Sub DataList1_UpdateCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Dim ID As String = DataList1.DataKeys(e.Item.ItemIndex).ToString() Dim title As TextBox = CType(e.Item.FindControl("textCategoryName"), TextBox) Dim image As FileUpload = CType(e.Item.FindControl("FileUpload1"), FileUpload)
[Code] ....
It shows the error in the line
SqlDataSource1.UpdateParameters("image").DefaultValue = image.FileBytes Value of byte can not be connverted to string
I also change the sql datasource parameters for image from object to byte
I have a stored procedure that creates a dynamic query. Sometimes the query is not built because there are no elements in the dynamic query. When the aspx page loads the SqlDataSource throws an error that the query is malformed. How can I catch this error, and handle it with a default message, before it returns the error to the aspx page?
I have an existing project with a silverlight3 app. First I created SALESservice.svc.This is working fine. Now I added another TARGETservice.svc to my project and rebuilded my entire project but when I am trying to add the service reference in to the silverlight app I get the following error:
There was an error downloading metadata from the address.verify that you have entered a valid address. I didn't write any code in ISALESservice.svc AND ITARGETservice.svc . I have written in SALESservice.svc.cs AND TARGETservice.svc.cs files.Is this causing error? But for SALESservice.svc it is working. I didn't add any code in web.config file.
I have a gridview in an update panel which is declared in an ASPX page, and bound to a SQLDataSource in code. The gridview's 'allowsorting' attribute is set to true, and because it is bound to a SQLDataSource, I expect the sorting to be automatically handled.
Yet I am getting the "Message: Sys.WebForms.PageRequestManagerServerErrorException: The GridView 'grdStatusItems' fired event Sorting which wasn't handled" error. I am using Visual Studio 2008, IE8, IIS7. What am I doing wrong? I have done anextensive search for this error, but it seems in most cases where this error occurs, the people are not using a SQLDatasource, so have to handle the sorting event themselves. Is this the case here? Here is the updatepanel and gridview declaration in the aspx file:
I get the Erorr: Input String was NOT a correct format.
The first three controlparameters are STRINGS and they work fine.
However the last two populate the controlparameter from text boxes that can only accept numbers and decimal point.
First the text boxes for {3} and {4} string parameters in the SQL filterexpression: [Code]....
And then the SQLDatasource control parameters[Code]....
The last two control parameters are the ones is question as they feed {3} and {4} parameters in the filter expression, NOTICE how I set the type="double".The data input is expected to be like 152.25 or 3.6 or 4 etc,So why am I getting this error: [Code]....
My ASP.Net 3.5 book just came in and I started reading the chapter on ADO.Net.
In the first portion of the chapter, it kind of hinted that writing code to access data was the old way (ie Creating a connection, command and datareader object and programmically binding the reader/dataset to a control).
It says that you should use one of the Data Source Controls, such as the SqlDataSource Control.
Is it best practice to start using Datasource Control like the the SqlDataSource Control or are these mainly for 'RAD'?
I'm putting the finishing touches on decent size ASP.Net application, I coded the Data Access Layer and I am wondering if I should have used the Data Source Controls but I always associated them with Rapid Application Development.
