Reading Multiple Node Attributes And Adding To DataGridView?
Sep 22, 2009
I am currently trying to read an XML file and display the information within a Datagridview. I currently have this working using the below
Dim xmldoc As XmlDocument
Dim xml_nodelist As XmlNodeList
Dim xml_node As XmlNode
xmldoc = New XmlDocument()
xmldoc.Load(openFD.FileName)
[Code] .....
Basically what I want to be able to do is for each <ADVERT> node, so in this case there would be two, I can get the information from both the TITLE and NAME attributes and add them into the Data table which then gets displayed within the data grid view. Currently I can only get the TITLE attribute values to show?
i have a treeview which has a bunch of parent and child nodes preset at design time, there is 1 parent node tho which is called developer, that i want to add child nodes to at runtime.When the form first loads im trying to have it check a text file and for each line in the text file add the text/string from that as a child node tot he 'developer' parent node.
vb Dim reader As String = My.Computer.FileSystem.ReadAllText(Application.StartupPath() & "ConfigDevs.txt") Dim strs() As String = Split(reader, Environment.NewLine) For Each s As String In strs
[code]....
Thats what i have so far, how can i set it so 'Dim parentNode As TreeNode = ' points at the 'Developer' node?
I need Xpath of the "element" in above XML using VB.Net NameSpace Manager For the "body" node i have done and its working but i couldnt do the same to "element":
dim bodynode as XMLNode=XML.SelectSingleNode(//ns:body,nsmngr)
where "nsmngr" is the namespacemanger created by me and "ns" is the name space of the "parent node" (which the "body" node inherits) added to the namespace manager as "ns"
I am trying to Add multiple rows to a datagridview using the below code, but at the moment it only adds 1 row and when i click add again it overwrites the previous entry and not add a second row: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim dt As New DataTable() dt.Columns.Add(New DataColumn("Make", GetType(String))) dt.Columns.Add(New DataColumn("Model", GetType(String))) [Code] ..... How do I manage to append the previous entry in the datagridview so multiple rows get added?
I have a windows applicatin built using vb.net 2005 - backend webservice that uses a sql db. I'm working on a form that contains a datagridview that I bound. My pic below to displays the outcome. I have a combination of dropdowns, textboxes, checkboxes, etc in the grid. I now need to add several filters and would like to know, what is the best approach:
1) adding the filters to the header row in the grid.
2) adding the filters outside of the grid as you can see i've started to do from looking at the pic?
I've been reading how it's possible to add them to the grid; but not sure if this is possible to do this when there are controls other than text boxes inside the grid.
I'm trying to get the price out (90.0) of this xml document but get it to work, i've tried using the xmlTextReader and the ReadElementString function but I guess I need to get the attribute. I then looked at using the GetAttribute function.
The First Splitter will be a ':', then the next one will be a ;. Per each line up there, I need to add that content into a row into a datagridview, So if you were to look at the datagridview, It would look like that data above exactly, But separated into the correct columns.
The following function copies a file from Source & Path to Dest & Path, normally setting file attributes to normal before copying.Yet, a user of my app has reported it to fail when copying readonly files, returning a permissions-related error. The user is however running the code as administrator, and the error happens - quite strangely - on the SetLastWriteTimeUtc line.Although the code reports that the file attributes are set to normal, windows explorer shows that they are set to read only.
I'm having an issue trying to figure out how to extract certian attributes from xml elements. Everything I have tried outright doesn't work or it concantinates the data. Here is the xml that I am trying to extract the 2 attribute values from an xml element.
I can't figure out how to get my code to evaluate the grandchildren of a specified node, where the grandchildren have two attributes which need to be evaluated to determine if the combination exists in the xml file. The function should return true if the two attributes of the grandchild node exist.
i want to add a node just above all removable drives from the thread I asked about in before. I decided that I don't want to have "C:" as a node, instead I just want my program to be the node. I've worked with this before but i can't figure it out without messing up what I already have.
I am now trying to get grandchild nodes in my treeview, i have got everything working, BUT instead of the nodes being put 'IN' the child node they are being put 'BELOW' it.
I have a problem with the database and the DataGridView. After editing the attributes of the database you can not see changes in the DataGridView. If you connect the DataGridView through code connection is correct. What could be the reason? What could be the fault of pliu nmd_piDataSet?
(When I plug the same database under a different name everything works as it should.) I have a table with about 20 columns and I can easily edit szeroość, view columns, using the code is problematic and not so intuitive. [Code]
I have a datagridview in which I am dynamically creating the rows and columns. I'm trying to set specific cells font to bold and not sure how to do it!Below is my code and what I'm trying to do.
I've made a Context menu that adds a new node to the control. But it doesn't work. Private Sub ToolStripMenuItem10_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripMenuItem10.Click Maps.BeginUpdate() Dim i As Integer [Code] ..... What I am trying to achieve is for example map1 is already there so if you add a new map it will add +1 to the i and return map2 etc.
I have a DataGridView, bound to a dataset. All the columns are sortable (.ColumnSortMode.Automatic). The user may change data in certain columns, although not the first ("key") column. When data gets changed on a row, I change the backcolor for that row (to show it as dirty). At some point, the user will do something with all of these changes.
My problem is that I still want the user to be able to resort the data by any of those columns. When it's sorted, though, I lose the backcolors that I changed. I do know which rows are dirty, this is just a cosmetic issue. Isn't there a way to retain those backcolors, or any other such row attribute?
I'm trying to accomplish something similar to:[URL]...However, I find the author's approach to be a bit cumbersome and "hackish" when I know this may be doable from within the application or at runtime.
I am populating a TreeView with a list of cameras. Depending on certain properties of the cameras, I'd like to add certain images to that camera's node.The obvious limitation is a single image per node by default.
I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts
I'm developing a windows application. I have a form in which there is a list box and a treeview control. My purpose is to fill treeview according to list item clicks. This is done using a pair of subroutines called ReloadPermissions and FillMenuItem:
Private Sub ReloadPermissions() Dim p As New Permissions Dim i As Integer Dim it As TreeNode Dim el As New List(Of String)
[Code]...
There are only two subroutines in which nodes are added to treeview control, and they are subroutines above. The problem is that whenever list item is clicked, node count displayed in treeview is increased!!! I checked number of nodes before and after call to tvPermissions.Nodes.Clear() using MsgBox. Results show that number of nodes isn't increased (1 before call, 0 after call, again 1 after ReloadPermissions() is called), but what is displayed doesn't show such a behavior! Refreshing window by putting it under other windows or call to tvPermissions.Refresh() has no effect.
I would like your advice on the following:I'm making a program in which a client can send an SMTP mail and stores the date, name and subject into an xml file. This works perfectly.Also made a form in which the client can view the send items, this form reads the xml file and places the data in a datagridview. This also works
Dim verzonden As New DataSet verzonden.ReadXml(CurDir() & "verzonden.xml") verzonden.Tables(0).DefaultView.Sort = "Datum DESC"
I created a tree view and I would like to know if (and how) I can add to a given node a datatable (displayed in a datagridview) with a click on the same node. Let me know if my question is not well described.
