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?
View 3 Replies 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.
Here is data binding expression (dropdown list is nested in gridview)

The whole reason for passing the reference is to save round trip to database and not to use SESSION
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
The above error occurs with gridview control , when used with template field columns with item template / and edit templates etc.
updating a row within gridview, at the time of loadiong it loads perfectly fined, but when tried to modify an existing row within gridview control, then it produces the error. Make sure the grid view control has to be a child control which manages the child table info with in a master form. to reproduce the above problem the grid view must be loading the child records info of a master within the masterform, meaning both master data and gridview data all to be managed in one single form.
I had to replace gridview control with datagrid and then it worked perfectly fine. I wasted almost 4 days of my time., there is no way we could figure out the problem. here is the full info of the problem.

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?

I'm trying to implement a recipe search page that allows users to specify search criteria by selecting checkboxes that match desired recipe attributes. All the data is stored in a database uing tables with 1 - many relationships. Each recipe can have multiple attributes from any of 5 attribute tables. I want to find all the recipes that match the user-selected criteria and display them in a grid. For example, the user may want a breakfast (attribute 1) recipe that is made with fruit and milk (attributes 2 and 3), is low-fat and high fiber (attributes 4 and 5), and takes less than 15 minutes to prepare (attribute 6). The query for this example might look something like:
SELECT distinct recipes.name, recipes.difficulty, recipes.preptime, recipes.cooktime
FROM recipes, recipeMeals, recipeDishes, recipeFoodGrps, recipeNutrients, recipeFixTimes
WHERE recipes.id = recipeMeals.recipeId and recipes.id = recipeDishes.recipeId and recipes.id = recipeFoodGrps.recipeId and recipes.id = recipeNutrients.recipeId and recipes.id = recipeFixTimes.recipeId and recipeMeals.mealId in (1) and
recipeDishes.dishId in (5) and recipeFoodGrps.fdGrpId in (1, 6) and recipeNutrients.nutrAttsId in (2, 3) and recipeFixTimes.fixTimeId in (1)

I have a web page devoloped in visual studio 2008.I have 4 dropdowns and a repeater in the page.based on the selection(search criteria) from the dropdowns the repeater value will change and one dropdown selection will bind values to the other dropdown also.Since the page is causing a lot of postback we decided to implement ajax here.I am yet to learn ajax.which ajax control replace dropdowns?
i have already server side code written on all dropdowns.Please give me a good solution which i can implement in less time and reuse my code.One more update: i have a master page used in the project.I am using update panel of ajax which does not work if i use master page.(That means all the dropdown controls and repeater i put it in update panel.But still page postback occurs.)In a normal page(without master page) it works?
