Forms Data Controls :: Setting Properties On Web User Control In Dynamic GridView

Jan 7, 2010

I am in need of some assistance in regards to how to best set the values of properties for a Web User Control which is being included into a cell of a GridView with dynamically created columns. I have tried a few different approaches, but can't seem to get a satisfactory result. Also, to be completely honest, I am not really sure if I am using best practices for what I am trying to accomplish.

First off a little background:I have a GridView for which we will never know the exact number of columns at run time. The columns are predicated by user selection. I am creating the command text for the DataSet on the fly and then looping through the columns of the resulting DataTable in order to use custom TemplateFields. This works ok for just printing out the row values but not so much for when I need to insert the Web User Control into a cell.The Web User Control is in essence a collection of image links which are used as a "Quick Nav" tool. I need to pass the values of 2 fields from each DataRow to the control via properties (for example, CustID and ProductID). I am using custom TemplateField classes inheriting from ITemplate for displaying my fields and extending the DataBinding event like so: [Code]....

This won't work for my User Control as DataBinding is called after the control is loaded into the page and I need the properties to be set before the Page_Load event of the control is fired.Is there a GridView event I should be looking into instead such as RowCreated or RowDataBound? Or should I modify how I loop through the DataTable by doing rows first, then the resulting columns as I've seen done elsewhere?

Web Forms :: Setting Page Properties From Itself?

Oct 8, 2010

Is there any easy way to set properties of a Page (or UserControl for that matter) from *within itself*?As an example, I have several .aspx pages which inherit from exactly the same code-behind class, but I need to be able to pass different properties to the class to make them do the correct thing for the specific .aspx.
The only way I've found to do this is to create the following - which works fine, but doesn't feel right....

<script runat="server">
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Init
Me.MyProperty = True
End Sub
</script>

It would be a much nicer, simplier and easier solution to be able to be able to set MyProperty = True somewhere... is this possible?The option of hard-coding properties within the class for the "parent" page is not going to work for my situation.

Web Forms :: Setting The Properties Of USerControl From Values In C#?

Dec 15, 2010

I have some user controls which have properties which need to be set from a form on the page

<uc1:MyPlugin

Property1="Hi"
Property2="0" Property3="<%=Property3%>"
Property4="<%#Property4

Property3 and Property4 anre both public properties of the page I am on and the user control

Currently the code complaing about Property3 saying it cannot create an object of Int32 from '<%=Property3%>' and Property4 always gets set to 0 (the default)

I do not wish to use the c# code to set these values as this Plugin will be deployed with a CMS which I have no control over

Web Forms :: Setting Properties Within BasePage Class Not Working?

Jan 11, 2010

We are trying to use a BasePage class (which inherits from Page) to populate and set the Meta Keywords and Meta Description Tags. I am using masterpages and below is an example code extract... According to examples on the internet, I could then set this also via the Page Directive using the MetaKeywords and MetaDescription properties, but they do not appear.

I have tried setting the CodeFileBaseClass="MyNamespace.UI.BasePage" but this does not work either. Using debug I can see that the BasePage classes' MetaKeywords and MetaDescription properties are not being set within my content page. I can access the properties but not set them.

Web Forms :: Dynamic User Control And Setting Properties?

Jan 25, 2011

I have a user control (i.e. ascx) that comprises of two related list boxes (i.e. once you change the selected item in one list the contents of the other list update). I'm adding this user control dynamically to a page on the click event of a button (i.e. using LoadControl).I wish to set the list box datasource properties, as well as the default selected item of the parent list from my parent page so I created public properties in my user control to accomodate this. I also created an event in my user control that notifes the parent page when the selected item changes in one of the list boxes so I can update the contents of the other list box.

I understand that I have to recreate the user control on every postback in order for it to function correctly but I'm not sure exactly how I should be doing it. I've shown below what I have currently - whilst it works the problem is that on postback I'm always creating the user control with all its default properties and then updating the properties that need to change(?). For example, when the choice in theparent list box changes the datasource of the list box is set twice (once in AddControl and then again in OnParentChanged)? As the contents of the list boxes originate in a database it means I'm making unnecessary calls to the database (unless I do some something like store each unique set of data in the ViewState).

I'd be very grateful if someone could review how I've done things and illustrate how perhaps I should be doing things. I'm not sure if the way I've done this is considered the 'correct' way. For example there may be a better way of doing things would avoid setting the properties twice? I'm a bit unsure of the way I've set the datasource properties of the list boxes and bound them. I wished to set the datasource from the parent page because I might have a second user control on my page that may also use the same datasource and I could reuse it (as opposed to each control making its own call to the database) so I'd like to keep this feature if possible.It would be great if posting code in reply that you use my example as a guide so I know what you're referring to.Here's the code for my user control:

Order Of Precedence In Setting Properties?

Feb 4, 2010

Some settings in asp.net like viewstate can be controlled at the site (web.config), page, or control levels. What is the order of precedence? What happens, for example, if I set viewstate of site and page levels but on at the control level?

Also, is viewstate for a control the same as control state? Furthermore, what events to use for loading and saving viewstate for controls (is this the same thing as control state?) and also for custom controls?

Similarly, which events should I use to render controls? Is this PreInit and Load? Is this the same for custom controls?

Setting Values For Invisible Fields / Properties In DetailsView?

Mar 16, 2011

I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:

If Not IsPostBack Then
DetailsView1.DefaultMode = DetailsViewMode.Insert
Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox)
txt1.Text = "administrator"
End If

But this returns an error of "Object reference not set to an instance of an object." how to accomplish this - either using the method above or another method? The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"
