Using PagedDataSource.CopyTo To Send Data To Repeater
Nov 11, 2009
I'm populating a Repeater with a PagedDataSource and after I populate that Repeater, I want to perform some other operations on the subset of data that makes up the page I'm sending to the Repeater (my CurrentPage Index, PageSize=10). So my question is how to get at those 10 records?
From reviewing MSDN, it looks like I should be able to use PagedDataSource.CopyTo to copy that to a System.Array, but I seem to be getting "Index was outside the bounds of the array." (I'm not sure how I need to be setting the bounds of the array from the PagedDataSource.)
Alternatively, I'd be happy if I could get those records into a SqlDataReader or any other way to read them and do more with them other than just displaying in my Repeater (again, looking for the records from that page that I set as the DataSource on my Repeater) Or, am I going about this the wrong way and is there a way to pull these back out of the Repeater?
I am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.
Something similar to that.
row1 tour1 row2 tour 1 tour1 subtotal
[Code].....
but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater
I'm writing a Repeater Control in an ascx file which renders some info as a row that comes from a complex search. In an aspx file I have the query to retrieve a DataView that gives me the XML string with the info needed to feed the Repeater. The problem is that I don't know how can I pass the XML string (or the DataView or DataSet) from the aspx to the ascx file so as I can render the info.
I have a parent repeater with nested repeaters.My problem is I am trying to use 'Next' and 'Previous' buttons to rebind my repeater (rptTabContent) and thus the inner repeaters also, but when I try to manipulate the state of these links during the ItemCommand event they are overwritten by the bind.
I have created a BitArray which is 11 bits long.I want to convert the BitArray so I can save the bits to a SQL server database field as a binary [varbinary(50)] so I can retrieve it at a later date and convert it back to a BitArray.Using examples on MSDN I have cobbled together the code I think I need.
Dim myBits As New BitArray(11)
I have populated the bitarray with 11111111111 for the purpose of testing ' Creates and initializes the one-dimensional target Array of type integer.
Dim myByteArray As Array = Array.CreateInstance(GetType(Byte), 11)
Note: from the above MSDN description this is an array of type integer - is this correct? I think it is a type 'byte' ?
' Copies the entire source BitArray to the target BitArray, starting at index 0.
myBits.CopyTo(myByteArray, 0)
I wanted to print the contents of myByteArray to a console to see what was going on. MSDN provided these print methods
Public Overloads Shared Sub PrintValues(ByVal myArr() As Array) Dim i As Object
For Each i In myArr Console.Write(ControlChars.Tab + "{0}", i)[code].....
trouble is, I am getting the following error which suggest I havent succesfully created the byte array:
Error 2 Overload resolution failed because no accessible 'PrintValues' can be called without a narrowing conversion: 'Public Shared Overloads Sub PrintValues(myArr() As Integer)': Argument matching parameter 'myArr' narrows from 'System.Array' to '1-dimensional array of Integer'.[code].....
I had using this code to show the alert_value in repeater. But it no output is shown in the column dso. I want to count the number of alert_value which is above than 150 which the alert id is dso.
Dim dso1 As Label = CType(e.Item.FindControl("dso1"), Label) If Not IsNothing(dso1) Then Dim name As String
I have an ASP.Net Repeater I want to use to show From and Text from a dataset and I want to add it programmically. I have all the data in a dataset and can use that and I have verified the correct number for datarows when it loads so the data is their it is just not showing. What have I missed?.
Dim data As New Data Dim ds As New DataSet ds = data.LOADALL() Dim drMsg() As DataRow = ds.Tables("MESSAGESYSTEM").Select("TOID='101'") repeatMessages.DatagSource = drMsg
[Code]...
How can I fix this code to show the data in the Message table?
I have placed a button on data repeater (called datarepeater1) so that it is repeated with other controls. When I click this button, How do I access/reference the text value of a textbox control called TxtAnimalID on the same row? (This would be something like the current row I am on).
I am trying to place a repeater within a repeater using xml data. I have it working exactly as I want, but the method I have used reloads the data for each repeater. I think I need to cast as an XmlNode but I'll be honest - I have no idea where to start. Here is my code - I'd like to keep everything in the code behind if possible.
I have a repeater which has a hidden field of Parking_ID <asp:HiddenField Value='<%# Eval("Parking_ID") %>' ID="HiddenField1" runat="server" /> and a Button under it.
I tried binding the value to the button from the html, it is giving me an error which indicates binding did not work. The programming language for the form is C# How can I bind the value of Parking_ID with its button in order to pass that value to another form? and how it can be passed to the other form?
I have used a data repeater and linked it with the data source. The program lists all the names of clients from the database with an ID number and also a URL.My first question is how can i make the url that is displayed as a link label, link to the default browser when clicked. I normally use the Shell("c:/program files/internet explorer/iexplore.exe "URL HERE") command but i'm not sure how to make this work with the data repeater?
My second question is to do with starting services, i need to take the ID number from the current data repeater record and then place it within a service name, for example if the service was callled Client_** the two ** represent the client ID. This then needs to start the service when button is clicked on the current record on the data repeater.
My third and final question is how to query a field in a current record of a data repeater, for example if i wanted to query a field called ID for that current record shown, is there a function i need to use to call the information?
Does datarepeater control has a bug? I tried to anchor a text box control inside the DataRepeater.Item, but it didn't work. At the property window, I set Anchor = Top, Left, Right. Anchor Right doesn't work properly.
Normally, when populating controls with data from a database I create a connection and then pass a SQL statement to create a DataReader. I then loop through the DataReader and populate the controls. Because I am creating the SQL statement on the fly I can query the database joining on multiple tables to get just the columns and rows I need.
Now I'm trying to use the Data Repeater control in VS 2010. The Data Repeater is part of the Visual Basic Power Pack add on. If you don't have it, it is similar to the Data Grid. I've never used the data grid because I found it lacking. I need more control on how to display the data. The data repeater seems as though it will work in this particular instance.
So, following the numerous on-line tutorials I created a new data source and a new dataset using the wizards. I pointed the dataset to a table in my data source and then bound the dataset to the data repeater. It works but the dataset is bound to a table. I can think of very few instances where I would need to dump the data from a table on to form. I need to be able to query the table.
I need to be able to pass a SQL statement to the dataset at run-time. It needs to be able to retain the bindings to the controls or I need to be able to bind the controls at run-time. No property jumps out at me for changing the dataset SQL statement at run-time. I can't see how to bind controls on the data repeater at time time. I can bind a data set to a data repeater at run-time, but I can figure out how to bind the controls to the dataset fields at run-time.
I have several UserControls in an ASP:Repeater. They are 'Add to basket' User Controls with a text input for quantity and a button to add the item to the basket.
My problem is the value is being reset to 1 whenever I enter a value into the quantity text box. I think this is happening because the containing page reinitialised the repeater (which holds the UserControls) and the quantity is one again before the UserControl's click event is fired.
how to capture the value in the textbox before the Postback occurs, I am happy to stick this data in a session for now.
I am thinking I need something along the lines of PreLoad? But that didn't work for me
I have a Data Repeater to which I need to add x number of images depending on their existence in the database.I need the images added within hyperlinks for Javascript functionality. In order to dynamically add the hyperlinks and images I have placed them within a panel in the data repeater and am adding them in the ItemDataBound event.The problem is that only the first image is being written to the datarepeater.[code]
Definitely data repeater is a very nice control. I can't remove the border of the data repeater control.It appears black by default. how to remove the border of the data repeater? I am using data repeater in my c# windows based application.
I wanted to set a repeaters datasource via an array. So, found numerous examples, downloaded (copiied) set them up and wham NONE worked. Afte 3 dayas of frustrarion an confusion I switched to c#, downloaded examples and THEY worked; so I then converted the code to VB, and yep, they didn't work. I'm really having trouble w
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Dim a As Integer() = New Integer(9) {}
I have a user control inside of a repeater that is being bound by a sqldatasource. I get the following error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. EDIT: NEVERMIND Egg on my face. I was getting this databind error because I was binding it somewhere else in an effort to troubleshoot my real problem from last friday but I forgot about it.
WHAT MY REAL PROBLEM IS: The usercontrol is getting bound before the properties get set so it appears as if they are never set. When stepping through I see that they get on the property is hit before the set on the property is hit. For example if I put <%# EVal("Address_ID") %> before the user control I will see the ID displayed but then the user control will display an emptydatatemplate because it is being passed the ID of 0.
I have a Data Repeater in a Windows Form, within the data repeater I have a label and either a radio button or combo box, the amount of radio buttons and the text for them is brought in from my database as is the label and combo box.
The label is a question and the radio buttons or combo box allows the user to answer the question.
What I want to do is get the checked status of the radio buttons so I can then reveal the next question if it is needed. e.g. only show question 2 if question 1 is answered No.
I am using datarepeater to display rows of information from database. When i click a 'save' button and i would like to loop through the rows of data in repeater. The code i am using is able to do all these. The only problem i encountered is at the Interface side. When i am looping the data-repeater. The selection 'frame' (refer to the picture point as 'A') is moving from record to the next record and scrollbar is auto moving as well to scroll to further down until the last row where looping finish.Is there anything can be done to remove the selection 'frame' and stop datarepeater from scrolling while looping the datarepeater.
