Add Rows Inbetween Rows In Gridview Based On Parent And Child Node
Jan 19, 2011I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.
Insert SQL 2008 Parent And Child Rows In A Single Transaction?
Nov 13, 2010First, a little background (greatly simplified): I have two classes, one called Entity and one called Item which a subclass of Entity. They each store their individual properties in seperate SQL 2008 tables using TableAdapters generated by a strongly typed DataSet. The Entity class has a Save() method that looks like this:
Public Sub Save()
entityTableAdapter.Update(entityRow)
End Sub
[Code]....
Indeed, the SQL table does not contain a row in the Entity table with the necessary ID at this point because the transaction is not complete.
My goal is to prevent the Entity record from being inserted if inserting the Item record fails. I could write code to delete the Entity record again, but this does not seem very elegant to me...
Sql - Inserting Multiple Parent Rows And Multiple Child Rows For Each Parent With ADO.NET In One Setting
Nov 28, 2011I am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.

Setting A Value In Parent Row For A Column That Is Grouped Sets Child Rows To Nothing
Apr 13, 2012i have a Janus grid, which has two columns and the rows are organized in a hierarchical order i.e. parent and child rows. One of the columns in the grid is grouped (by dragging the column in the group by box above the grid). I have a cell-changed event that is fired when a cell content is changed. I do this in the cell-changed event:[code]If i change the value, in a parent row, of the grouped column then the child rows are set to Nothing. After the last line in the above snippet, child rows of row are set to Nothing. On the other hand, this problem does not occur if i change the value of the other column (which is not in the group by box). The problem occurs only if i group a column and change its value not otherwise.

Checking Treeview Nodes - If Parent Is Checked Check All Child Nodes
Aug 31, 2011I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

VS 2008 : Adding Parent And Child Nodes To TreeView?
Oct 31, 2010I am not sure I am getting the concept of referencing nodes in a treeview. When I hard-code nodes like:
tnParentNode = New TreeNode("ABC")
tvReports.Nodes.Add(tnParentNode)
tnParentNode = New TreeNode("Some Other Company")
[code]....
I get two parent nodes and one child off Some Other Company. However, when I pull information from a couple of tables to set up the parent and then the child nodes, I only get the parent nodes.So I pull the main parent nodes from one table and the child nodes from another table.This code pulls the parent nodes without any problem:
strSQLText = "SELECT lID, sCatName FROM Category ORDER BY iSortOrder DESC"
reader = GetReader(strSQLText)
While reader.Read
[code]....
But this does not add the child nodes. I am assuming it is because of the first line in the above reader.read while loop. I must not be referencing the proper parent node but I am not sure how to do it.

View 1 RepliesTreeview - Check All Child Nodes On Checking Parent Node?
Jul 6, 2011I was wondering how I would go about placing a check in the checkboxes for each child node of a parent node in a TreeView control, if I was to check the parent node.
For example:

Child 3
If I was to check "Parent 1" how would I be able to make that event place a checkbox beside all of the child nodes of "Parent 1"? (Child1, 2, and 3.)
VS 2008 Highlight Rows In A ListView Based On Specific Conditions?
Oct 12, 2009I have a ListView that I populate with running processes and would like to highlight specific rows based on the amount of memory consumption. After I add the processes to the list and and call the WorkingSet64 property of the process, I tried this:
vb.net For Each lvi In ListViewProcess.Items If proc.WorkingSet64 >= 2000 Then lvi.BackColor = Color.Yellow End If Next
Processes is the variable I used to grab the collection of processes. proc is defined as a variable and then used to loop through the processes.
lvi is of course the ListViewItems in the ListView.So, by the code I have above, I loop through the ListViewItems, and if any of the processes are above or equal to 2000, then I set the background color to Yellow.
However, it sets every line to yellow, and I can't seem to figure out to set only those processes that have a WorkingSet64 above 2000.
Would I need to loop through the processes and then set the background color of the ListViewItem based on that? That kind of makes sense to me, but if I do that, I'm not sure how to set it just for those processes. Maybe by setting a separate variable?
MySQL Count Rows Count Rows And Gain Access To Other Information In A Row Based On Provoided Information
Oct 8, 2009I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)
So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).

Filter Parent / Child Table In Linq Query Based On Entities In Child Table?
Jul 9, 2010I have a table (Projects) which is linked to projectVersions on projectID..projectVersions contains several columns on which I'd like to filter a returned project (and associated projectVersions) list. For example there is a "capacity" column and a "country" column. I am doing a filtered list of projects on one page and I'd like to include all projects where any one of the associated projectVersions has a capacity of 750ml and a country of "France" for example.It may be that a particular parameter is not set and so I pass a zero to indicate not to filter on that.I guess this needs some kind of subquery as when I try and do something like this: [code] it doesn't work as the "xxx" bit, being one-to-many, expects me to specify an item to get at the entities within and yet I want to query where ANY of the associated versions match one of the criteria.

View 1 RepliesDatabase - Binding To Parent Rows In WPF?
Aug 1, 2011I'm fairly new to VB.net and WPF (and programming in general), so please bear with me. I'm attempting to write a useful database app for my business as a learning project. I did a draft in WinForms, referring to the (very good) Murach book, but am now trying to re-write it with a WPF UI and cleaner code.
I think I understand the basics of WPF binding, but am tearing my hair out trying to find a simple way of binding to parent details - which I would have thought was a very basic scenario, but I can't find anything on it. For example, let's say I havea 'Customers' table with CustomerID, Name, various contact details and then foreign keys CityID and GroupID;
[Code]...
And then just moving to the first record (as there will only be one). Is this a normal method of looking up a customer? I could also use this method by getting the foreign keys from my customer row and filling the different tables in the dataset all using parameterised queries, then just binding to each table separately - but again, seems very messy.
