Forms Data Controls :: Binding To The TreeView Control?
Sep 14, 2010
My TreeView controls is rendering CheckBoxes on Leaf nodes. I want to bind to those nodes the ID of the underlying data item. I am not sure I can do this declaratively or if I need to hook up to the TreeNodeDataBound event. If the latter, how would I go about achieving this?
I need to show this array in a treeview in this way: When the person has ID finished in 00, it is showed how the father node, and the other persons starting with the same letter are the child nodes.
In this case Andy would be the father indented 0, and john and lina would be his childs indented 1.
I need to show this structure in a checkbox treeview and when I select the father checkbox, the child checkbox must be selected too.
I have a treeview associated with an XML Datasource but the treeview loads only the xml node names whereas i want to assign the values in the xml nodes to the treeview instead of typing <databinding> for each node in the source file. I want to write code which dynamically read the xml nodes and populatethe treeview or is there any property which will read the values also ?
i am developing a tree view component which should be data driven and amendable instead default layout provided by .net can we change that proper hierarchial structure like organization chart is there any chance to provide with an hyperlink to redirect other page or content view control below to display the content related to it.
Is it possible to get the unique URL of an expanded treeview node? I need to be able to send the URL to someone and he should be able to navigate to that particualr node from the URL.. so I guess I need to somehow use a query string with the treeview control?
i'm trying to implement a grouping repeater control. And i've followed the link:http://www.aspcode.net/ASPNET-grouping-repeater-control.aspxcould any one please tell me how can i induce one more lvel of grouping? i.ewhen treview control is clicked, it should contain another treeview control with n-levels of repetition.
Could you point me to a reference article on how to implement drag and drop within a treeview control using ASP.NET in C#? Is this best implemented with AJAX? I will be using an XMLDatasource. Also, I did not want to use any third party control at this point
I need to display the innertext of the each node as items in my menu along with count (i.e; NewObject1(1), NewObject2(2)). I m using treeview but not able to bind this to treeview using xmldom
Xpath being://Request/NewObject/Object/text(). But not able to read text() attribute to treeview. <root> <Request> <NewObject ID="1"> [code]......
i want to replace the control after binding like suppose i bind a gridview with the edit button . when i press the edit button all field are come as a textbox control. i replace this textbox to another control how to do this.
I have a DevExpress WebChart Control that binds to a DataTable. The chart control renders fine from the DataTable until I try to import data from a details view(i think the chart control renders before the detailsview?).
Here is three renderings.
Chart 1. just rendering from the datatable
Chart 2 The sqldatasource gets its para. from the values of two label controls to render the detailsview. The detailsview renders fine
Chart 3, the problem comes in when I try to extract the values from the DetailsView to populate the Chart, I loose the value. I am assuming the the datatable is built before the rendering of the detailsview? Lost at this point.
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 details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns). My problem is that I am unsure how to bind these to the field from the database on postback. I.e. I am trying to find the code behind equivalent bind('currency');
I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.
I'm a bit of an ASP.NET newbie and I am creating a data table in memory and binding this to a gridview control. The code is as follows:
Dim DstBasket As New DataSet, TblBasket As New DataTable With TblBasket .Columns.Add("BskPrdCd", System.Type.GetType("System.String")) .Columns.Add("BskPrdDesc", System.Type.GetType("System.String")) .Columns.Add("BskQty", System.Type.GetType("System.Int16")) .LoadDataRow(Split("12345,Test product 1,1", ","), True) .LoadDataRow(Split("122,Test product 2,2", ","), True) .LoadDataRow(Split("123A,Test product 3,5", ","), True) .LoadDataRow(Split("44,Test product 4,1", ","), True) End With DstBasket.Tables.Add(TblBasket) With LfnGridView("GdvBasket") .DataSource = DstBasket .DataBind() End With
The data displays in the gridview control fine with both edit & delete options but when I attempt to delete, it has no effect. How do I force removal of the relevant row from both gridview and table? Most of the documentation I have unearthed shows how to achieve this when connected to a SQL table which is clearly not the case here.
I don't know what I'm doing wrong but for some reason I'm not able to maintain the index selected value on the listview that I've created within a user control. In a user control I have added a listview. I have exposed the handler, Datasource and DataKeyName. I have populated the datasource of the listview by using the following:
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;
