Is there any way to avoid having unwanted fields generated into MVC views by the default VS wizard? It would be nice if a ScaffoldColumn=false annotation could achieve this, but it doesn't.
Of course I have a mile long wish-list regarding generated views, e.g. I would prefer EditorFor as a default for all generated fields. I suppose this is T4 and T$MVC territory only, or are there other tools?
I have written a t4 template that basically replaces the work done by StronglyTypedResourceBuilder to give design time access to string resources as properties of classes, one class per resource file. Why? Well I needed to add some customer code that handles string token substitution and a few other customizations. Anyway, the template is working out really well and I may blog on it soon.
In the mean time though, following a common pattern, I have one .resx file for each view, master page, controller, etc. I would really like my t4 template to add a property to each such entity that gives quick access the custom resource class associated with it. For controllers this is easy. T4MVC is ensuring that they are a all declared partial. All I need to do is create the appropriate partial class in my output that declares a readonly property that returns an instance of the appropriate generated resource class.
The Problem:
I would like to do the same thing, inject generated code, into my views. Were this traditional ASP.Net, each .aspx page would have a .aspx.cs page and possibly an .aspx.designer.cs page that are all partial classes extending in the aspx page's class definition. There is no such thing by default in MVC and for good reason. However, I think for my purposes, if there is a way to do this, it would be the way to go.
I could subclass ViewPage and add a generic type parameter and a property that returns the class of that type but that has certain complications. I think adding auto generated code to each view via partial class (that is what partials are for after all) is the way to go.
I have made a basic attempt. I have created a .aspx.cs file for a view and placed a code behind attribute in the page declaration but the class generated from the view seems to reside in a different assembly any my "partial class" ends up as its own class in the same assembly as all my other code.
i m trying to add new field named mobile in my create user wizard control for that in my web.config i add
profile
enabled ="true">properties>add
name ="Mobile"
type ="string"/>properties>profile>
in my create user wizard using edit template i add one textbox named 'txtmobile'
nd in my cs i write
CreateUserWizard2_CreatedUser
{
ProfileCommon p = (ProfileCommon)ProfileCommon.Create(CreateUserWizard2.UserName,
true);
TextBox txtM = ((TextBox)CreateUserWizard2.CreateUserStep.ContentTemplateContainer.FindControl("txtMobile"));
p.Mobile = txtM.Text;
//p.Mobile = ((TextBox)CreateUserWizard2.CreateUserStep.ContentTemplateContainer.FindControl("txtMobile")).Text;
p.Save();
}
but it throws the error of 'object reference' nd also let me know how to store that field in db?
Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.
Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.
i have jst been told to work on an ongoing project say www.xyz.com ... apparantly, for running the downloaded files on my local machine, i had to create a virtual directory say DIR ... now, the problem is that whatever files i downloded in DIR have gone one level down in the path specified in the code ... for eg. For accessing the local file for http://www.xyz.com/home.aspx , the url comes out to be http://localhost/DIR/home.aspx ... which is making me go to each and every page and modify all the respective links to point to files under directory DIR ... Is there any way that i can omit the virtual directory name from local url ??. or is there any way out of the problem .. BTW i m using Visual Web Developer 2008 .
View 3 RepliesI have a web application.
I user Forms authentication and set Login.aspx as the Login url.
So when I try to enter any other page in my address bar Iam redirected to Login page as per its setting.
But now I need to give a link called Register in Login.aspx page.
Clicking on Register link should take me to Register.aspx page.
But as per authentication settings Iam redirected to Login page.
So is there a way to omit or escape the register.aspx page from this authentication setting.

View 15 RepliesI have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller,
View 1 Replies I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:
txt_first_init.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"].ToString();
txt_last_name.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"].ToString();
ddl_pregnancy_flag.SelectedValue = formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"].ToString();
And conversely when it's time to submit.
formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"] = txt_first_init.Text;
formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"] = txt_last_name.Text;
formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"] = ddl_pregnancy_flag.SelectedValue.ToString();
I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.
So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.
I am using TempleteFields for all columns in my GridView. In that columns I am using only some fields for customization but not all.
Is there any performance issue with Databound Fields vs Templete Fields in a GridView...?
Do I need to replace the remaining columns with Databound Columns instead of TempletField columns...?
I am working on Crystal Reports 8.5 and SQL Server 2000 as backend. I have a stored procedure which has been added to the Crystal Report. So that fields are visible in the Fields object section from where i can drag and drop the fields on the report and display it. But now as they want more fields i have written two select statements for displaying required fields. But these newly added fields are not visible in the Fields object section in the Crystal Reports. I have done verify database, removed and again attached the SP but the problem is not solved.

I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?

View 1 Replieswe have an asp.net web site (web application project of vs 2005) where we have a main project and same secondary projects which contain same apsx/ascx used by the main project.
for example in an aspx page of the main site we will use same ascx defined in another project)
at least with vs 2005 we must do a lot of hack to make it works becouse it's not possible to directly reference another web application to use aspx/ascx defined there.
i want know if upgrading to vs 2010 and mvc can help us to a better organization of this type of architecture (the best things will be if i can add a view as embedded resource of a project and i can use it by another project, as the server control of asp.net form)
