Forms Data Controls :: 'System.Web.UI.WebControls.GridViewRow.DataItem' Is A 'property' But Is Used Like A 'method'?
Mar 29, 2010
I tried translating this from vb but getting the error on e.Row.DataItem("CustomerID").ToString i tried varios things but no gooddbSrc.SelectCommand = "SELECT * FROM Orders WHERE CustomerID = '" + e.Row.DataItem("CustomerID").ToString + "' ORDER BY OrderDate";
What i am having trouble doing is set the current parameter to the current row at a specific column like e.row[column index]
For Each trow As TableRow In table.Rows
cmd1.CommandText = "dbo.directway" cmd1.CommandType = CommandType.StoredProcedure cmd1.Connection = conn [code].... Class 'System.Web.UI.WebControls.TableRow' cannot be indexed because it has no default property.
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 a problem that is really confusing me.. I'm trying get get info from a database and populate the relevant labels. I've got it working on one page, but not on another. The only difference is that the one that works is in a repeater.
My code is as follows:
[Code]....
The error I am getting is the following:
Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS0117: 'System.Web.UI.Page'does not contain a definition for 'DataItem'
Back in my vb.net days, I had a gridview, that when a user clicked a select button in a templatefield, I could determine the row that the user selected. Trying to do the same in C#, but am lost in translation somewhere as it throws this error when trying to get the value. This is what I have, but it throws an error.
When I move some web-based code from VS2008 to VS2010, I find it is different when it is hard to handle the Image class.
Let's take the following code as an example.
[Code]....
As I have already imported the System.Drawing namespace, I still cannot use Image.FromFile method as VS2010 detectss the Image class is in System.Web.UI.WebControls namespace.I have lots of such a kind of code in my project using Image class and I will get messed if need to modify the code from
i am usingVWD 2010 andwant to create a website supported under .net 3.5. The deafault mater page has the loging pgaes already set up (.net 4.0) which is very good and helping to start. But once i changed my project to run under .Net 3.5 , i could not have the account register webpage working and getting this error : Parser Error Message: Type 'System.Web.UI.WebControls.CreateUserWizard' does not have a public property named 'LayoutTemplate'.
am duplicating a site from a prexisting site. I am getting the error 'System.Web.UI.WebControls.Literal' does not allow child controls when my web application goes to process a function that implements keywords, description, title ect for a webpage. This is quite perplexing as it i not doing this in the website i duplicated from.
[Code]....
it looks at Header, i dont think it can find the definition in this second website so it is returning System.WEB.UI.EmptyControlCollection. In the first website it is returning System.Web.UI.ControlCollection. Also when I go to the definition for Header, it opens up the Metadata definition in the first website. In the Second, it says "Cannot navigate to definition".
I created a custom clander server control basing on "System.Web.UI.WebControls.Calandar" and when i change the culture from login Screen (Ex:- Spanish) i am setting only the UI Culture in the page base class. When i had the Both "CurrentUICulture" and "CurrentCulture" set i could see the Day (Mon Tue) of the my custcalander control in the corresponding culture, but when i commented out i see them in English only (not in the corresponding culture set while loggin in. The reason why i commented out the "CurrentCulture" was that when i set this the middle tier or code behind files also running in this culture (as we are setting on the CurrentThread culture) and causing decimal data coming in this culture (Ex:- spain) and so on. So i only set the "CurrentThread.CurrentUICulture" only to corresponding culture and not the "Thread.CurrentThread.CurrentCulture". Is there a way to acheive this, i mean How to make the Day (Ex:- Mon, Tue, Wed) in the corresponding culture with out setting "Thread.CurrentThread.CurrentCulture"?

I've built a class that derives from System.Web.UI.WebControl. It basically renders pagination links (same as what you see on top of GridView when enabled) for use above a repeater.I'm creating some anchor tags explicitly inside my nav control obviously, but they don't perform ajax postbacks. My understanding is that ajax requires POSTS to work right? Well, these would be GETs
I have a listview and a dropdownlist that is pulling from an SQLTable that I am using to insert data into the ListView, which is associated with the SQLTable. For the life of me I cannot figure out how to get this thing to not allow duplicate entries into the listview.
If I could get at the data that is inside the ListView I think my problem would be solved. At the moment all the code I have is to simply find if I can at least get the data down to something I can compare, from that step I will have no problem writing something functional, at least functional for my needs. I really could use a hand with this:

I don't personally have access to the SQLTable, but I can have somebody make changes if this should/needs to be done from that end, but I would rather do it from this end in VB. I've been digging through the MSDN Libraries
This is my first "request for help" post - I've spent the past few weeks helping others, so I'm hoping someone can shed some light here.I've dealt with server controls before, so it's not new to me, but it was some time ago and I'm a bit rusty. I have an inherited calendar control, that works fine:
[Code]....
I've overriden the Render method, hoping to be able to modify the HTML output of the control - I want to hide the back arrow if the Month & Year in MinDate is reached in the calendar, and the same goes for MaxDate and the forward arrow.On top of this, I want to be able to display icons in the day cells, under certain data-bound conditions. Once I've figured one out, I'm sure I'll be able to work the other one out.Are there any other methods, events or properties more suitable for this? Are there any other controls that do what I'm looking for that I've maybe overlooked?I'm using C#.Net 4.0 Webforms - it's a very small app, so I've not used MVC etc... just a few LINQ queries to the database.
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()
I am accessing a DetailsView from the following event
public void dvDetails_DataBound(Object sender, EventArgs e)
I am casting the sender to my detailsview like so
DetailsView dv = (DetailsView)sender;
Now when I look in "dv" I can see the DataItem property has the data I want in it under a field name, but I dont know how to write the code access the value??
The field name is shown in the dataitem property as "_DTMON_F", I tried to say
'm getting the above error on one server (production of course, it's always production). On two other servers and in my local dev server, the exact same code runs fine. I do see the Display property has ThemableAttribute(false) in the documentation, so the fact that it IS working seems to be the anomoly, but how could this be working in 75% of the environments I'm testing in?
Protected Sub FormView1_ItemCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewCommandEventArgs) Handles FormView1.ItemCreated Causes Unable to cast object of type 'System.EventArgs' to type 'System.Web.UI.WebControls.FormViewCommandEventArgs'.
The program (asp.net/vb) works fine with FormView1_ItemCommand and FormView1_ItemInserted events but strangely objects to FormView1_ItemCreated. Is it only a VC# event?
FYI, In databse I have stored dropdown item text, not value.
Now whenever I try to set the selected item using following code, I am getting error System.Web.UI.WebControls.ListItemCollection.FindByText(string)' has some invalid arguments.
