I am in need of getting the correct sysntax for being able to use paging with a datalist whose data is being generated by a SQL Datasource and a stored procedure inside the aspx(asp.net VB...Not C#) page. A Gridview or any other rigid control that does not allow full control and layout will not work so I have to use the datalist. I have the datalist working perfectly but I need to add paging. I did some searching and found a good solution. It was a C# solution, in particular the code behind syntax so I used a code converter to convert it to VB. However, as I am not an experienced coder I need help converting the portion for handling the datalist. I am fairly confident I have the buttons on the aspx page worked out. I will ask that if you se something I need to do besides the section(5) I have listed please offer suggestions. So that you can help me better I have boken the code out into sections where I'm listing the code I copied, my code and the section I need help with. I think at a minimum I will have to change the references of Repeater to Datalist.
The section I need help with is section 5 where the original autor is referencing items generated in the Repeater where he used XML. As I said I'm using a SQL Datasource with a Datalist so I truly don't understand what I need to change to get the code behind to work with my Datalist. As always I appreciate all of you guys and ladies help. And also as always I will ask to please provide the actual code to type in because telling me how to do it just won't help very much. Sorry about that.
Here is what I have: SECTION 1 - The buttons to handle the paging ******************************************* <td> <asp:label id="lblCurrentPage" runat="server"></asp:label></td> </tr> <tr> <td> <asp:button id="cmdPrev" runat="server" text=" << " onclick="cmdPrev_Click"></asp:button> <asp:button id="cmdNext" runat="server" text=" >> " onclick="cmdNext_Click"></asp:button></td> </tr> ********************************************
SECTION 4 - Public Property CurrentPage() As Integer Get ' look for current page in ViewState Dim o As Object = Me.ViewState("_CurrentPage") If o Is Nothing Then Return 0 Else ' default to showing the first page Return CInt(o) End If End Get Set Me.ViewState("_CurrentPage") = value End Set End Property Private Sub Page_Load(sender As Object, e As System.EventArgs) ' Call the ItemsGet method to populate control, ' passing in the sample data. ItemsGet() End Sub
SECTION 5 - NEED HELPING IN CHANGING TO WORK WITH DATA LIST *************************************************** Private Sub ItemsGet() ' Read sample item info from XML document into a DataSet Dim Items As New DataSet() Items.ReadXml(MapPath("Items.xml")) ' Populate the repeater control with the Items DataSet Dim objPds As New PagedDataSource() objPds.DataSource = Items.Tables(0).DefaultView objPds.AllowPaging = True objPds.PageSize = 3 objPds.CurrentPageIndex = CurrentPage lblCurrentPage.Text = "Page: " & (CurrentPage + 1).ToString() & " of " & objPds.PageCount.ToString() ' Disable Prev or Next buttons if necessary cmdPrev.Enabled = Not objPds.IsFirstPage cmdNext.Enabled = Not objPds.IsLastPage repeaterItems.DataSource = objPds repeaterItems.DataBind() End Sub
Private Sub cmdPrev_Click(sender As Object, e As System.EventArgs) ' Set viewstate variable to the previous page CurrentPage -= 1 ' Reload control ItemsGet() End Sub
Private Sub cmdNext_Click(sender As Object, e As System.EventArgs) ' Set viewstate variable to the next page CurrentPage += 1 ' Reload control ItemsGet() End Sub
I'm trying to setup a page that will utilize a dropdown list control inside of a grid view control using VS 2005 2.0 version. Everything that I can find online seems to only show the use of the dropdown list control using a data grid. I don't want to use a data grid because it doesn't have the functionality/ power as the grid view control. how I can incorporate a dropdown list control with the grid view control? Here is a copy of my code.
I have question about dropdownlist control.I have a dromdownlist control which shows the list of dealers.I want to add a sub-list to each dealer which should populate the products available at that particular dealership.I don't want to select value from sub-list display.
I have a form in which I have a dropdown list and a list box.
This dropdownlist is populated by a column in thetable . This drop down list may have values ranging from 1 to 5.
This values in the dropdownlist are to be made the caption headings of the list view control.
For insance if there are three values in the dropdown there should be three columns in the list box with the heading as the values of the dropdownlist.for 5 it should be 5.
Also there are two additional columns which would be constant.
I have a list box in a list view control. I want to access the value of the listbox. I have fixed the height of the list box and the box has scroll bars. If i change the number using the scrollbar and then click on the number (turning it blue) everthing works fine. If I simply change the number using the scrollbar the system throws the error below. Can anyone tell me how to get this to work simply by using the scrollbar to select the number (without having to also click on the number itself) This is the error that is thrown

I have a formview in which I have a dropdown list that displays a list of owners. In case the list does not have the correct owner for the user I have added functionality for them to add a new owner to the database table that populates the list. I did this by including a textbox and an Insert button in a panel. When the user clicks the new owner insert button I would like to re-databind the dropdown list so that they will see the owner they added and be able to select it.
When I add ddl_owners.databind to my button click code it gives me an error. "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I don't want to re-databind the entire formview because then it deletes all the information on the form that the user has already keyed in.
How can I bind a datalist control with a list of objects. I have a list of objects that contain a name, desc, and url for menu commands that I am trying to show in a DataList. I am getting the list from a WCF service so I have a list called something like menuList which consists of a List<MenuCommands>. I then do a menuDataList.DataSource = menuList and then a menuList.DataBind but nothing is happening. What am I missing here? I need to use a DataList because I need the commands to be selectable.
I am using a listview to show multiple labels with Book names and price.I have included a dropdown list in the listview. On index change of dropdown list price of book is changes.
I am using UpdatePanel to avoid post back. I hav placed "Loading.." image in ProgressControl.
But when i use dropdown list to change price then "Loading.." image is shown on all the rows of list view . but im just changing it on first row but image shows on all the rows.
I need to bind a List control based on the Gridview Row's datakeyName value while the Gridview control is being loaded into the page. I tried the following but it does not work.The BulletedList control is nested inside a Gridview Control and they both bound to an ObjectDataSource control. In my code, I passed teh UserID into the UserID parameter and call the Select() method but still does not work. Basically, I want to list of a user's hobbies, therefore the hobbies control are driven by the userID. tell me how can I get it to work?
protected void UserGridView_RowDataBound(object sender, GridViewRowEventArgs e) { int UserID;
I built a user control that displays a drop down list of states. I'm using it, but if I try to put it in a listview control, all I get is the frop down with nothing in it.
I'm trying to follow this article on cascading dropdown list in a GridView control in edit mode (except I'm using C#) [URL] I keep getting this error message "ProjectID is neither a DataColumn nor a DataRelation for table DefaultView."
I have drop down list box that I would like to show two columns, is this possible? Or can it be done with a list box?The query correctly retrieves all of the table data to be displayed, one colum is an abbreviation, the other a bit longer description.
I have a databound dropdownlist and have a problem with the default value it selects.When I attempt to edit a record the dropdownlist shows the first value in the list rather than the current value. I want the dropdown list to display the current value.
I'm sure this is very simple but I'm very new to ASP.NET.
