Forms Data Controls :: Building A GridView Programmatically?
May 9, 2010I have problems building a GridView programmatically. My code is:
[Code]....
This displays the GridView with the following problems:
1. The Html constructed in the Subject column displays on the page as raw Html. The source code shows the Html characters in their ASCII form. The function HTMLEncodeSpecialCharacters is obviously incorrect.
2. The PagerSettings display the page numbers only (1 2 3 4) and not the First and Last text (want to display << 1 2 3 4 >>) despite setting PagerSettings.Mode = PagerButtons.NumericFirstLast.
3. Clicking the page numbers is always one page behind. For example, when the page is opened, page 1 displays. If I click 2, page 1 still displays. Then click 3, page 2 now displays. Click page 4, 3 displays. Click 2, 4 displays etc etc.
4. The column headings are aligned in the centre despite setting HeaderStyle.HorizontalAlign = HorizontalAlign.Left.
Forms Data Controls :: Building Gridview With Text Search Criteria?
Mar 13, 2010I have gridview that I am filling with records from SQL database. However, I want to populate the gridview with records that match text search criteria. In other words, I want to be able to key in a word like "network" in a text box, pick up the text, read records and pick up on the records that match that criteria. I am doing fine with building the gridview but I am a bit new to this and I don't know what I do to do text search.
View 3 RepliesForms Data Controls :: Looking For Clean Approach To Building Nested Datalist Or Nested Gridview
Jun 17, 2010Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

View 3 RepliesAjax - Server Controls And Building HTML?
Jan 26, 2011I render HTML returned from an ajax call and currently uses simple html controls and the string that is returned from the ajax call looks like this:
string s = "<tr><td><a href="#">MyLink</a></td></tr>";
Now, on the click on these links I need to do some processing on the server side to determine where I need to navigate to and for other information. My understanding is that I cannot use <asp:linkbutton /> in this html string I am building. How do I make a server side call if i don't want to use ajax.
Web Forms :: Dynamic Controls Versus Building Dynamic Page
Jan 28, 2011Lets say I have a Web Application with a menu of products. When a user clicks a menu item, then create and display a dynamic set of controls in an Update Panel. I am currently doing this however the PostBack and recreation of controls is tedious and resource intensive.
Not sure about this but is it possible to build a webpage with controls on it, then display it in update panel or IFrame? Then on post back you wouldn't have to recreate everything all over again?
When Building A Datagrid Helper How To Access The New Data Annotation Attributes Using Reflection
Feb 3, 2010So I've eagerly added the System.ComponentModel.DataAnnotations namespace to my model.
I've added things such as:
[Required] [DisplayName("First Name")]
public string first_name {get;set;}
I really like these attributes because they save me from having to write custom T4 and/or modify views heavily. This way, I can regenerate a view confident that it will add the display names I want, etc.
The problem comes in when I started building a DataGrid helper inspired by the one in ASP.NET MVC2 unleashed. In this helper, Stephen uses reflection to get at the column headings.
var value=typeOf(T).GetProperty(columnName).GetValue(item,null) ?? String.Empty;
Well, the trouble is I don't want to retrieve the property name. I want to retrieve the value for the DisplayName attribute.
My first attempt at this was to look inside the Attributes property of the PropertyInfo class. Unfortunately, none of the data annotations show up as an attribute.
Is there a way to retrieve the data annotations using reflection?

Aug 9, 2010How can i check a parameter value and add onto or remove conditions from my where statement.Here is what i mean.. i have a stored procedure that is being used for returning small set of fields based on a parameter that it is expecting. Since the only difference between the select statements are the last AND condition, i was wondering if i can check that parameter as im doing now but change that AND condition so that i have only 1 select statement instead of 3 within my procedure.Current Example:

DataSource Controls :: Building String To Pass Into StoredProcedure From CheckBoxList?
Jul 1, 2010I have a CheckBoxList that I need to get the values from, concatenate, and pass into a stored procedure in SQL Server 2005 utilizing Visual Basic. Due to the way our data layer is I cannot use a SqlCommand object at this level.
I have no problem getting to the selected values in the CheckBoxList:
Dim selectedValue As New StringBuilder
For i = 0 To cblMethods.Items.Count -1
If cblMethods.Items(i).Selected Then
selectedValue.Append(cblMethods.Items(i).Text)
End If
Next
The problem is that I do not know how to list the values in such a way that my stored procedure will pull data:
SET @MethodNames ='GetWords','GetLetters'
SELECT * FROM TABLE WHERE method IN ( @MethodNames )
I've tried experimenting with apostraphes but cannot make it work:
selectedValue.Append("'''" + cblMethods.Items(i).Text + "''', "

View 1 RepliesCustom Server Controls :: Building A User Control To Track Page Visits?
Mar 25, 2011My intention is to give the user a flexible user control on a master page that does the following:
When navigating, a child page will pass the URL (with querystring) and PageTitle to the user control. The user control will take those two parameters and insert them as a "breadcrumb" object at first index of a List<breadcrumb> collection
This part works fine through the use of a Repeater with a LinkButton contained in an ItemTemplate. The user sees each of the pages he has been visiting in descending order, the provided benefit is a quick way to re-open records they have recently modified or created.
The part I'm having trouble handling is what happens when the user clicks the LinkButton, which is that the child page adds a new reference to the URL at the beginning of the List<> collection and I cannot seem to control the behavior of removing the LinkButton before it gets re-created. What I've tried doing is:
List<>.RemoveAt(RepeaterCommandEventArgs.Item.ItemIndex);
Repeater1.Controls.Clear();
Repeater1.DataSource = List<>;
Repeater1.DataBind();
While that should work, my CreateBreadCrumb(string url, string title) function gets called by the child page before the UserControl detects the Repeater1_ItemCommand event, so in effect it appears that the wrong ItemIndex is being used for removal.
Web Forms :: Do Need To Run Compiler.exe After Building The WAP
Mar 10, 2010I'm having trouble with a WAP (web application project). It builds fine within studio (and it uses a number of other assemblies which build before the web application). However, I've always used aspnet_compiler to publish web sites in the past which is then deployed to the server. So I'm building the WAP solution (including assemblies) then publishing just the website folder and not the assemblies within the solution.1) Do I need to run aspnet_compiler.exe after building the WAP. I guess the WAP build causes the bins to be created correctly but the ASPX pages are still uncompiled?

C# - Building A Forms System Using DDD?
Feb 25, 2010i'm building a form managment system, thats is, the system will contain many forms, will save them, and perform logic on them, I want to do it using the DDD approach.
I want to support easy form layout later on using ASP.NET MVC, so far i see the domain like this:
I'll have a base form entity, which should(for now) have a name, fields(and theire values) and validation logic.
My questions are:
How should i write the field valueobject using generics? i cant seem to figure it out.. Should i encapsulate the validation logic inside the form or do it using the specification pattern?
