Mar 17, 2010
I am getting the following error :
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'p2_area_name'.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'p2_area_name'.
Also, I need tp populate data from database in the Area dropdown but not able to do so..
I am having a problem about my gridview when it binds to an accessdatasource.
The error appears:
"DataBinding: 'System.Char' does not contain a property with the name 'Firstname'."
Here's my gridview:
[Code]....
Here's my code behind:
[Code]....
The error occurs when the selected index of the DDL is 1 and I have to bind it in an accessdatasource. First condition is working fine where I will check a value and put all items that matched the date criteria in a data table and then bind gridview in the data table.
The error is just when I bind my gridview in the accessdatasource.
AccessDataSource1.SelectCommand = "Select Firstname,Middlename,Lastname,Jobseeker.IdNo,SchDate,Time,Venue,JobPosting.JobCode,JobTitle from JobPosting INNER JOIN (Jobseeker INNER JOIN ApplicationProgress ON Jobseeker.IdNo = ApplicationProgress.IdNo) ON JobPosting.JobCode = ApplicationProgress.JobCode where PostingHr = " & Session("Id") & " and SchDate = '" & Date.Today.ToString("dd - MMM - yyyy") & "' " GridView1.DataSource = "AccessDataSource1" GridView1.DataBind()
using sqldatasource with a listview to insert and show results from an SQL server db i want to try using the LINQ datasource since it seems to be more flexible in codebehind.
My problem is this: i droped a listview control to the page and i created the Linq datasource in codebehind with vb. the issue that i am having when i ..Select d.columms name i get the error system.string does not contain a property with the name "columname".. if i ommit the column name then its works fine.. i get the error.. code below:
vb code
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim rowsCount As Integer Dim showSearchForm As String showSearchForm = Request.QueryString("tab") If showSearchForm = "1" Then

b.dbMake needs to work so that i can use Distinct ,, ia m using asp.net version:3.5 and IIS version 7.0 .. not sure what i am missing ,, but i did try alot of approaches,,1- checked the web.config file and it seems to have two assemblies and two namespaces for LINQ..2- used different databinding syntaxs,,and i searched a lot for the solution.. the last one i read the person ommited the name of the column,, i thought that wasnt the best solution.. also my dbMake column is comming up in the "intellisence" ..
When I was creating a datasource for the List box - it showed the correct data,but when I tested it on the Web - I see a listbox with 3 lines of value:"System.Data.DataRowView". After manually deleting a row from the database - I see only 2 lines. After deleting all rows from the table - the listbox is empty.
So why I don't see the table values, but the string "System.Data.DataRowView"?
I'm trying to figure out how to find whether a column exists in a dataset, and if not, remove certain controls on the page (otherwise it will error out with: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'my column')

I have a gridview that has xml data loaded dynamically by drop down list selections. The xml elements vary depending on the file.
I'm receiving the following error on this code and I can't seem to find the solution. "CS0118: 'System.Web.UI.Page.User' is a 'property' but is used like a 'type'"
I have developped a usercontrol, but I can't seem to find how to databind on a property of the usercontrol in a detailsview.The property is defined this way:
<Bindable(True, BindingDirection.TwoWay)> Public Property Value As String Get[code].....
I'll use Customer and Addresses as an example rather than explain my real objects. Say I have a repeater bound to a collection of Customers and one of the properties of Customer is an array of addresses. How do I bind to the addresses property? I don't even need to display this information I just want to use it in the Repeaters ItemDataBound event. So I tried to bind a hiddenField to the addresses property but all I get for every customer in the hiddenfields value is an empty array of addresses.
In this case I use a datasource control for a datalist and the parameter list is being built ba the system. The DBType is created for the smalldatetime feild
i have an Gridview with BoundFiled, for the bound field headertext alo coming from the table, but i dont know how to bind the headertext and data. i have used below code
I have an ASCX that inherits from a WebControl that has a 'CustomConfiguration' property of type CollectionConfigurationItem. This configuration gets set elsewhere in the code, so by the time it gets to the ASCX it is set up to how I wish to use the data. At this point I'd like to render out another control using this configuration, like so:
However, breaking into DataModule always results in 'CustomConfiguration' being null, which is the default value for the property. I've tried adding a Bindable attribute to the property but to no avail, and when I set an EventHandler for the DataBinding event on the DataModule it doesn't even get called.
How can I set this custom-class-typed property from the markup or, failing that what's the second-best method of getting this to work?
I have a dropdownlist (drpClients) bound to an object datasource (odsProgramClients). In the dropdown's databound event, I load a dynamic table based on the selected item in the dropdownlist. This all works well. However, if I force a problem in odsProgramClients select method, it continues to the databound event of the dropdown and attempts to load the table, even though dropdownlists underlying select method failed. I wish to stop the databound event from firing if there is a problem in the select method. I have code that traps the error in odsProgramClients select method.

How do I stop the dropdownlist from databinding, if there is an error in it's underlying datasource?
I have built a site and worked fine for me, when I passed to a collegaue to deploy into another site he gets the message in subject.
