Iam using nested repeaters with Dataset (not using Datatable) to retrieve information by passing parameters. So far I have bind the two repeaters clearly and everything is working fine.Here the list of messages created by each user datawise(parameter passed) will be displayed, and there could be more than 50 messages created by each user daily, So now I want to do custom paging for each user.But Iam unable to proceed further, as the next, previous, back, first links are placed inside the child repeaters footer template and i coudn't access these links even by findcontrol method.
I'm trying to convert an asp.net website to a vb.net application. It's my first go with vb.net so please try and make any responses as simple as possible.On my website I have a page that uses nested repeaters. The data source is a dataset with relations.Im trying to replicate this in a form. I've created my dataset and relations, but I'm struggling to find the best way to display my data within the form. For each parent row there can be a varying amount of child rows. The parent row simply shows an index number via label. The child rows contain text that can vary from a single character to 1000 characters.I have tried to use a dataRepeater as the parent control and a datagridview as the child control.I'm struggling to find out how, and at what point, to bind the data to the datagridview.
I am a bit lost in concept how to implement what i want to do. I have a gridview, a checkboxlist. I bind the gridview on the page_load. Everytime user choose a checkboxlist, the gridview rebind as well. I have something like this now. This is not the actual code. Thanks so much.
[Code]....
So what do i put here in order to allow paging ? basically, I have 2 datatables in the above example. In the actual code, I have about 5 datatables with 4 checkboxlists. I can't use Datasource control. I need to do it in codebehind as all code already exists.
I have a nested class, let's call it class1 and it has class2 inside it; VB.Net eg:[code]
1) How can I define X number of Class2 objects[let's call it: Node(x) array]** with NEW() subroutine called?' this raises error: dim cls2(n) as new class2 end sub.
2) How can I return actual number of Node() array? [code]Outside my class in main project I define cls1 object:[code]Now an array of class2 is created inside cls1.
3) Now,How can I access All of them[node(x) array which is created inside cls1] with all properties and methods available?
I remember I wrote a ProcessManager class with this functionality in .net 2003, nearly 4 years age, I don't have the code now.
I have a MDI project that has a parent and several children forms. In some of the children forms I would like to make one of the forms to be a parent form with children. On this child form I wanted to make a tabbed MDI, which I can do, but I have found out that I can't make a child form a parent, from what I have found.
Is there any way to get around this? (As in nested MDI forms.)
I have a nested custom control that I need to set focus on. I have it all internally wired up to automatically set the focus when the form loads, but when it comes up on screen, the designated accept button for the parent form is in focus instead. Even when is disassociate the accept button it still does not set correctly. How can I ensure my desired control gets focus.
I have a custom component, that contains a list of another components.If I add a child component to the list, it shows up on the same level as the parent component in the document outline window.How can I make it a subitem of the parent component? (similarly to e.g. TabPages that are subitems of a TabControl)
Here is my code: Public Class SomeComponent Inherits Component
I have an RDLC report that I am rendering directly to the Response Stream as PDF (rather than using the ReportViewer). In the code that renders the report, it's DataSource is bound to a List(Of ClassA) objects defined in a custom assembly. This seems to work for the most part. My problem is that I can't seem to handle the situation where a nested object is null. For example, given ClassA and ClassB (the nested object) defined as follows:
Public Class ClassA Public Id As Integer Public Name As String
[Code]....
the report displays "#Error" if TheNestedObject is null. If TheNestedObject is not null, it correctly displays the Name.
I'm having lots of trouble understanding how repeaters are supposed to work and how I'm supposed to use them. Basically, I have a label, a set of image buttons, and a div within a repeater. When you click on the button, I want to populate the div that was created with these repeaters (so a different div for each iteration of the repeater).[code]I can't get the repeater to iterate. It's only firing off once and then stops. I can't get a label with the repeater data source's Subject (a field in my database) to appear.
[Code] I have a panel as the base of my custom control and I am adding other panels to it, along with a flow layout panel(myInnerContainer). I know the code above isn't going to work because when I try to add the regular panels to the main control, they will attempt to be added to the flow layout panel myInnerContainer, and cause a circular error. [Code] but intellisense doesn't display anything which leads me in the correct direction for adding only the buttons to the flow layout panel (myInnerContainer).
Im working with MDI parent/child objects. when closing the child objects i need the child to check to see if it is the last child object before closing. i couldn't find anything on google, maybe im searching for the wrong thing.
code For Each item As Reflection.FieldInfo In GetType(NameSpace.ClassWithNestedClasses).GetFields rtfAppend(item.Name & ":" & Tab & item.GetValue(Me)) Next For Each item As Reflection.PropertyInfo In GetType(NameSpace.ClassWithNestedClasses).GetProperties()
[code]...
which gets me the simple string vars and properties of my top class, but how can i apply this to loop through all sub classes and get there vars and props?
I am looking to close the application when I click a cancel button in a login page, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application. Here's the code that I have so far:
(in loginPage)
Public Event CloseApp As EventHandler Private Sub CancelButton_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles CancelButton.Click
I am making use of an ASP.NET Repeater.My Repeater is called myRepeater and I only want to display 20 items per page.Can this be done with a ASP.NET Repeater and if so what changes must I make to my code below? I want to be able to make use of paging. C# example is also fine!![code]
I need to quickly fill a datagridview but there are over 10,000 records.What is the best paging solution to use in cases like these ? Should I use a backgroundworker ?
I'm experiencing a problem when clicking on the page number within my ASP .NET gridview. When I click another page number, I am redirected to another unrelated page within my project.This wasn't a problem until I added jQuery to my masterpage, so I'm guessing there is some sort of conflict in the javascript code. When the aforementioned redirect happens, the page PageIndexChanging event isn't fired and there isn't a postback as far as I can tell. [code]
I am giving the Dapper ORM a try. I am able to query data from a table using the code below:
Dim comments As List(Of Comment) Using conn = New SqlConnection(ConnectionString) conn.Open()
[Code]....
how to do paging/sorting using Dapper. EF has "skip" and "take" to help with this. I understand that a micro ORM does not have this built in but would like to know the best way to accomplish this.
I have a simple query: Dim info As New SailMembersDataContext Dim query = From p In info.Individuals GridView1.DataSource = query GridView1.DataBind()
How I can add paging to this query for example 10 on a page I have tried to use the built in paging on the GridView but this just produces the error: The GridView 'GridView1' fired event PageIndexChanging which wasn't handled. When trying to change to another page.
I'm really struggling to make the leap in understanding to get paging working for my gridview. I am creating a web part in vb.net so have programmatically created all the controls. For development I have an aspx page to view my work. I have created a table with code and then inserted my code created gridview. When i enable paging i get the following error.
at System.Web.UI.WebControls.GridView.get_StateFormatter() at System.Web.UI.WebControls.GridView.BuildCallbackArgument(Int32 pageIndex) at System.Web.UI.WebControls.GridView.CreateNumericPager(TableRow row, PagedDataSource pagedDataSource, Boolean addFirstLastPageButtons) at System.Web.UI.WebControls.GridView.InitializePager(GridViewRow row, Int32 columnSpan, [Code] .....
"First, Last, Next, Previous" options to the gridview paging? i can't seem to figure it out. all i can get are numbers and >> for last and << for first...
how can i create paging in a grid control let say i have 100 records in the database.. upon loading the data to the 1st 10 records of the query should be shown.. then button NEXT and PREVIOUS provides the navigation.if i press next display the next 10 records, previous will display the 10 previous records
I'm writing a small web app in VB.NET and I would like to do paging for my DataTable in the following function :
Public Shared Function Testing(ByVal KeyWord As String, ByVal CurrentPage As Integer, ByVal PageSize As Integer) As DataTable Dim db As New BibleDataClassesDataContext
I am using a standart .net 2.0 Gridview which uses an XMLDatasource to populate the Grid. The Data property of the XMLDatasource is set dynamically which allows the gridview to change based on input.All this works fine however I am having problems with paging.I have set the AllowPaging Property to "true" and set the PageSize Property to "10". The GridView populates fine the first time around showing the first 10 records and the number of pages as hyperlinks at the bottom, BUT when i try to click on any of the page numbers to view them a message box pops up saying "Object reference not set to an instance of an object"..[code]
i'm using a datagridview to display the records which are filled in my dataset. however i need to perform paging to display only selected numer of records (e.g: display only 10 records per page) and by using the buttons (like: FirstPage, NextPage, PreviousPage, Last Page) allow users to nevigate through the records. and possibily display the total number of records in my dataset (e.g: |< last <Next 10/100 previous> first >| ) this might sound very simple but i'm new in .net and so far whatever source code i found in google is moslty written in C# which i don't know.
I am stuck at this part where I am unable to allow paging in the datagrid. I have tried this.
<asp:datagrid id="dgReport" runat="server" AllowCustomPaging = "True" PageSize = 5 OnPageIndexChanged="dgReport_Paging".... and in the code-behind, Sub dgReport_Paging(ByVal sender As Object, ByVal e As DataGridPageChangedEventArgs) dgReport.CurrentPageIndex = e.NewPageIndex bind() End Sub
i reading values from MSword an populated the vlaues in Datatable. there is no problem in this. then my datagridview must contain checkbox at the position of second column.so i have created the column programatically. then i have looped the datatable and added the rows in datagridview. [note: i am ot using Datasource Property because i need checkbox column at position.so i create the columns dynamically and add the values].
I want to add paging functionality to the datagridview in my windows form. I did a search in google and got some codes too but I am not able to implement in my code as the way I am binding data to gridview is different than the one shown by other codes (that i got from google). I have implemented update and delete also. So I dont want to alter my code but I need to add extra code to implement paging which i don't know.
