Loading Xml File Into DataGridView With Combobox Cells?
Mar 25, 2010
i have been hunting the web for a solution or example to my problem which is loading and xml file into DataGridView with combobox for the cells and then loading the comboxes with data that the user can choose from to change the cell value to and output an updated xml file. Below is my code with the column creation commented out for now, with this code the 7 columns are added with comboboxes to the datagrid but when I read in the xml file its adds the data to another 7 columns on the end and not into the columns I have created first.
Is it possible to load the content of a text file (.txt) into a listbox or combobox if the text file is located in a webpage?let's suppose that the file is located at url...how would i load the content of the text file into my listbox/combobox?
I've written the following sub to load a comma delimited file into my datagrid view but it's hanging up when it attempts to load the first two values into the cells of the datagridview. I think it's having trouble adding the cells to the datagrid. I have tried writting them directly using the .text of the specific row and cell but when I incremented to the next row it hung up because the row didn't exist (I think).
I generate my xml into "variable string str" by using "dataset.GetXml" and then I write the "xml which is contained in variable str" into "file.xml" by using sFile.WriteLine(str) while 'sFile' is a stream reader"My reason for using 'writeline' instead of 'dataset.WriteXml' because I need to encrypt the 'xml stored in 'str' before I store it into file.xml.I got everything fine for the encrypted result, and so does the decrypted result as well.Here's the decrypted result of my file.xml below (I have checked it the xml value which in str before encryption and which in decrypted file.xml. They are all match well)Here is my plain xml value before it got encrypted or decrypted which I stored it in variable str by using GetXml. I don't know for sure but my xml value doesn't contain declaration "<?xml version="1.0" encoding="utf-8" standalone="yes" ?>" like common xml used to have.All the xml file which I got from GetXml is just like below (No declaration like <?xml version="1.0" encoding="utf-8" bla ?>) Book 1 2010-09-22T14:43:00.0000000+07:00
And since I think it may not cause any problem then I keep coding and decrypt it which is going well and the decrypted result is perfectly same ofcourse.My problem is, when I try to make my xml value show in Data GridView by using the code below, and run the debug, it prompt an error said "could not find the file c:laFile.xml ".
ds = New DataSet path = System.IO.Path.GetFullPath(strFileToDecrypt) ds.ReadXml(path)
I am facing a "weird" problem with the DataGridView. In fact, I have a function, that loads each table of an xml file into a datagridview (27 tables all with same structure except one called Listes). In the datagridview I have a combobox column to select "type" (it's the 3rd Column, so it's index is 2 normally). The problem is that when I call the function loaddata for the first time, all work perfectly ! If I call it for a second time, to reload the data, I get an error of cast! I verified and it seems that first time I call the function the column that contains the combobox is column(2), but when I run it again automatically the indexes of the columns are changing and am getting the error, because the column that contains the combobox is becoming column (3) and that explains the cast error because the column'(2) is not anymore the combobox so the cast will fail ! What I can't understand is why it's reordering that way my columns automatically ?
Here is the code: vb.net Sub LoadData(Path As String ) Dim oData As DataSet oData = New DataSet oData.ReadXml(Path) Dim i As Integer Dim MaGrille As DataGridView [Code] .....
1) How can I load data from Text file to DatagridView. I want it because I'm making a listener. And when I load a data from text file, i want to edit rows. And this calling the second question. 2) How can I save data, Datagrid to Text file.
I found a code Dim obj_oledb_da As System.Data.Odbc.OdbcDataAdapter Public Function ConnectCSV1(ByVal filetable As String) As DataSet Dim dataSet As New DataSet [Code] ..... I can load data with this code but I can't save.
My Text File must be like this: #IP 127.0.0.1 localhost
So there's lots of examples of how to do this if your text file happens to be in XML format. However, my text file is not in XML format and as it contains over 172,000 rows I'm not that keen on adapting it (it's a dictionary)! The text file has been included in the project as a resource. So far I've got a DataGridView (could use a DataRepeater if easier?), a BindingSource and a DataSet.
The DataSet has a DataTable already defined in the designer with one column.I've managed to load the text file into a String and then create a StringReader based on that String variable, however I cannot find anyway of loading those strings into the DataTable.
Dim listWords As String = My.Resources.WordList Dim strReader As New System.IO.StringReader(listWords) 'What now???There are some examples of using OleDb functionality but all assume you're loading from a text file residing somewhere in the filesystem, not a project resource.(I'm also assuming that on building the application the resources get embedded (somewhere) rather than being accessed from [AppDir]/Resources/[filename] ??)
i would like to know the syntax for this.i wanna add the values of 2 cells and then i will display their total in textbox.i have been trying to use datagridview.rows.cells but i cant just use it to add to cells values.
i wanna compare my cells in datagridview. I have a datagridview with n columns and n rows. I have my datagridview row value as Time . I need to compare all the row cell values with one particular time.
Here you go with an example.
if my dgv is filled with time values such as 3:42:10 AM 4:43:17 PM etc..I need to compare all the cell values to 5:00:00 PM. greater than condition. I need to highlight only the values which are greater than 5:00:00 PM but less than 3:30:00 AM.
I'm current in college and working on some computing coursework and putting the finishing touches on it when i stumbled across a bit of a problem.I'm trying to compare two cells in a database and i use datagridview to display the database in my form. The database is created by sql commands within my actual program if that makes any difference. What i have created for my coursework is a program that manages the stock and such for a small music shop and in the stock table im trying to compare values in two different collumns, but in the same rows. I need it to display a message box in the event that the value in the one cell is less than the other, which is basically checking if the stock for a certain CD has fallen below the reorder level.
I'm trying to fill a DGV from a (List Of).. This is my code. It's not working & I don't know why..
Public AllBooks As New List(Of Book) Public dgvInventory As New DataGridView Private Sub BookDetails_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
I have a datagridview and I want to click on it BAD to jump to 4 cell, but to walkwith the arrows is normal, I did this because the KeyDown / UP does not work becausethe cells are in Edit Mode:
Private Sub DataGridView1_EditingControlShowing (ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) HandlesdgvContactos.EditingControlShowing Dim EditingTxtBox The TextBox = CType (e.Control, TextBox)
I'm completely newbie and I have been trying to solve a problem that is strongly related to what you guys had discussed here .
I have a datagridview (datagridview1) on my form and it is not linked to any database. I'm only trying to programatically enter values into the rows of the grid by values that my program generates.
For example if the value that my program generates is x, y, z then I would like to say something like[code]...
Is the following grid layout possible with DataGridView in VB.net? Kind of similar to html table layout. I'm adding data cell by cell. However I'm not sure on how to get the layout for Group A & Group B Cells. -------------------------------------------------| | Item11 | Item12 | Item13 | |-----------------------------------------| | Item21 | Item22 | Item23 | GroupA |-----------------------------------------| | Item31 | Item32 | Item33 | |-----------------------------------------| | Item41 | Item42 | Item43 | -------------------------------------------------| | Item51 | Item52 | Item53 | |-----------------------------------------| GroupB | Item61 | Item62 | Item63 | |-----------------------------------------| |Item71 | Item72 | Item73 | -------------------------------------------------|
How do I add the cell on my datagridview? I am not sure how to do that but I have four columns which I want to add the cell on 3rd column on my datagridview.
I have been working on a solution that uses Combo Boxes to fill DGV I have 3 RDM tables, 3 Combo boxes and 1 DGV Probably best way to explain tables is this way
Table 1 OwnerID 1, 2, 3, 4, 5 ( There are 5 owners)
Table 3 CDTrackID 1,1=(1-10) 1,2=(11-14) 2,3=(15-20) 2,4=(21-27) 3,5=(28-36) 3,6=(37-40) 4,7=(41-44) 4,8=(45-47) 5,9=(48-55) 5,10=(56-60) where 1,1=(1-10) means Owner 1 record 1 has 10 records and Where 1,2=(11-14) means Owner 1 record 2 has 4 records etc etc
On Form Load Combobox 1 loads all the data from table 1 with no output in DGV (Works well) (5 records Perfect)
When I select a record from Combobox 1 it loads relation data from table 2 into Combobox 2 and also displays same in DGV (Works well) eg if I select record 3 in combobox 1 it loads records 5 and 6 into combobox 2 and DGV (2 Records. Perfect)Now comes the Problem When I select a record from Combobox 2 it is supposed to load the relation data from table 3 into ComboBox 3 and display same in DGV eg Combobox 2 has records 5 and 6. If I select record 5 It should load 3,5(28 - 36) OR If I select record 6 It should load 3,6(37 - 40) instead If I select Record 5 then Record 1,1(1-10) loads into combobox 3 and DGV If I select Record 6 then Record 1,2(11-14) loads into combobox 3 and DGV Regardless of which record I select from Combobox 2 (1,2); (3,4); (5,6): (7,8); (9,10) it always loads the same records into combox 3 and DGV Sample code for combobox 1
SQL = "Select * From CD Where OwnerID-1 = '" & cbxOwner.SelectedIndex & "'" Sample Code for Combobox 2 SQL = "Select TrackName From CDTracks Where CDID-1 = '" & cbxCD.SelectedIndex & "'"
[code]....
The only thing I can think of is that my query constantly sees 2 records and numbers them as 1 and 2 thereby displaying records 1,1(1-10) OR 1,2(11-14)?
Im using vb2010 express. I have a datagridview in my form. All my cells in the datagridview has a "sunken" cellborder. When mouse is over a cell, i want to change the cell border of that cell to "raised". I tried lots of thing, but i havent suceeded to change just "one" cell's border.
I used this example to create a DateTime column for a DataGridView in my winforms app. [URL]I can see the new column in the Windows Forms Designer and add it to an existing DataGridView. However, I want to be able to change the display format when I change the "DefaultCellStyle" within the designer. The designer generated code looks like this:
I want to multiply or add the values of two or more cells in a datagridview control in a row and and should also be auto-saved in the database after entering datas in the cell. I am using SQL Server 2008 for my database.
I want the column/cell of my Datagridview to accepts double(1500.50). I declare the cells as TextBoxCell.
'In dgvw_EditingControlShowing event : AddHandler tb.KeyPress, New KeyPressEventHandler(AddressOf txtColDgvw_Keypress) 'Calling the Keypress of TextBoxCell Private Sub txtColDgvw_Keypress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Try
[code]....
It does not accept Double Or I cannot type a point(.)...
