Forms Data Controls :: Accessing Properties Of The GridViewRowEventArgs Class Within A Regular Method?
Jan 6, 2010
I have a regular method I want to call. I need to use properties of the GridViewRowEventArgs Class within this method.
i.e.
[Code]....
Of course the above code is not valid because I don't think you can put GridViewRowEventArgs within the method like that. I don't want to put it within a event handler because that even handler is doing other things. I want to be able to call this seperatley.
1) What Is The Meaning of dr.GetOrdianal In ASP.NET Class File? What Is The Purpose Of The Same? Is It Compulsory To Write dr.GetOrdinal While Fetching Any Value From Database?
And
2) What Is The Purpose of Properties (Get & Set ) In Class File? Will It Saves Our Time Of Compilation?
I have a problem, with a gridview. When I try to make a OnRowDataBound I get the error "Gridviewroweventargs is inaccessible due to its protection level" I cann't figure out why.My aspx code for the gridview:
[Code]....
Now I have comment out everything in the function grdWaitingApproval_RowDataBound:
[Code]....
When I remove the line in the aspx file
[Code]....
the project runs fine and I get a list of users with username date and so on. But I nead to use the RowDataBound to select a picture to each row.
I'm face of a little problem when using GridView, an EntityDatasource and entity custom properties using a partial class. I'll describe it and I hope that someone has already find the solution because I try to figured out since two days.
I have a Customer database table with a text field named customerPicture with the name of the JPG file.
I have made a Customer Entity class with the LinQ to SQL Designer.
I also have a FormView displaying Customer instance binding with a LinqDataSource.
My problem is:
I want to make some modifications when some control want to bind the customerPicture field.
For example, when my FromView want to show the field customerPicture I want to return not only the JPG file name, I want to modify this string to add the complete file path and perhaps resample the image to a determinate width and height.
I know that is posible to defeine a partial class named Customer to implement certains partial methods, like OnCustomerPictureChanged(), but I dont know how to do this.
If I make, in this Customer partial class, a new method, for example getResamplePicturePath(), how could I invoke it from a FormView?
I need to be able to access simple page controls like a textbox from my page class. So if I have a simple aspx page with a textbox on it, I'm trying to do something like this. i'm not using codebehind btw:
[Code]....
I thought maybe I could pass a reference to the page into the class, something like:
[Code]....
But that's not working either. How can I access page controls from my class?
I have several .aspx pages that all have identical code behind pages.For ease of maintenance,I would like all the aspx pages to share a common code behind page. To do this I have created a MyCommonClass class,which contains the common code.In the code behind of the .aspx pages, I have:
Partial class MyPage Inherits MyCommonClass End Class
But now the controls declared in the .aspx pages are not accessible in MyCommonClass.fix this?
I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):
Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating Dim entity As New Login() Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo) entity = accountControl.Entity e.InputParameters.Add("entity", entity) End Sub
My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:
Public Overloads Function Update(ByVal entity As Login) If entity Is Nothing Then Throw New ArgumentNullException("entity") End If MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _ entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax) End Function
When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?
In my application, I use nested master pages. In the main.master which is the top level, all encompossing master page, I have some properties. I want to set the value of this property from a user control embedded into the page which is using master page which is embedded into main.master. To clarify further, here's the hierarchy
If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.
Using the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService] public class Controller : System.Web.Services.WebService { [WebMethod] public void save_client(aClientArgs client) { // Save client data } } Then defining aClientArgs as a sub-class: public class aArgs { public string id = null; public string name = null; } public class aClientArgs : aArgs { public string address = null; public string website = null; } Returns the following WSDL fragment for the save_client args: <save_client xmlns="http://tempuri.org/"> <client> <address>string</address> <website>string</website> </client> </save_client> When I'm expecting the following: <save_client xmlns="http://tempuri.org/"> <client> <id>string</id> <name>string</name> <address>string</address> <website>string</website> </client> </save_client>
So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?
i have a web service that i use for the AutoCompleteExtender, let the below code show you what i'm trying to do: [Code]....
this method is called, and when it calls the method inside the Patients Class, it gets lost. does that mean that i can't use 3-tier approach with web methods?
i have a <div> named 'mydiv' on a web page and have set it's runat property as <server> so it is visible within
my vb.net server side code.
i can see the mydiv within the server side code.
my question:
how do i adjust the height/style of the <div> withion the vb.net code so that whe the page is posted back the new height/style settings apply. how do i get to the style properties server side?
I am currently working on a page that displays a set of questions as retrieved from an XML source. I can print the questions out fine by using a ListView and the ItemDataBound event. On PostBack it seems I can get some property values (Text), but not others (ID). I need to get the ID so I can match up the answer to the appropriate question.
Here is the ListView:
[Code]....
I just don't understand the Life Cycle stuff that well for advanced issues like this. I'd prefer not to use the Request.Form collection for this, but I will if it's the last resort.
I'm wondering how I can go about accessing page controls from a separate class I've made. I've tried a few things I found using google, but no luck :(
What I'm trying to do is keep a function that is used often, in a global class.
The function then accesses a page literal and calls ScriptManager.RegisterStartupScript. I was hoping this is possible, so then this function wouldn't have to be copied to all of the pages.
