i have started learning wpf and now i am up to datagrid.bit i am stuck here. coz the code which i used for wfa datagrid doesnt work with wpf. it gives many error.including for connection string.
i am working on my search button, and successfully the data can be display in datagrid. Now i have problem to display the data into textboxes by clicking on the datagrid.i use Microsoft access for my database.
I have a dataset that is being generated from an XML file.
This dataset has two tables (User and UserSecurity) - that is related because they both have the same primary key. [i know, the tables should probably be combined, but this is the data that I have to work with][code]...
I like to make a data grid that get data from a .csv and display on the table (note all the data is separated by ",") but I have no idea how to do this.
I have the code below where I want to be able to click a row/cell in a datagrid and be able to display the related data from the database table in the second datagrid. strSQL = "SELECT Number,Description FROM Legislation " Dim cmd As New OleDbCommand(strSQL, oledbcon) Dim tRow As DataRow da = New OleDbDataAdapter(cmd) ds = New DataSet da.Fill(ds, "Legislation") Dim i, j As Integer If DataGrid1.Item(0, i).Value() Then DataGrid2.DataSource = ds.Tables(0) End If
I have a SQL stored procedure that I bind to a Silverlight Datagrid. That works ok, the problem is when I use the same stored procedure to bind a different dataset to the same grid, it doesn't display the new data, only empty columns from the last dataset that was bound. What is going on here? I tried to set the grid = Nothing and I tried using Datagrid1.columns.clear() but that didn't work.
I'm trying to code a button which has a SELECT statement to get information from one table but I want the information displayed in a data grid view.From the data grid view, this data will be stored in a different table within the same database.Previously i had used a list box to display the information but i could not save it in the data base.[code]Is there any way you can display this on a data grid view like i did on the listbox?Im using a datagrid view textboxcolumn column.
I got a system which i want to insert, delete, update the data into my database and the data from database will be display using datagrid. The below is the coding for one of my button, delete.
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click Try btnSearchEmpNo.Enabled = False[code].....
Now I wanna set when user click on this button to delete a employee (for example) then the datagrid that i have in my application will not show the data of the deleted employee but in the background, the employee haven't been deleted from database.The employee only will be deleted from database when the user click on SAVE button.I know this application have to use RowState but how?
I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
I placed a datagrid in my form which l retrive data from my sql. i am using oledb connection. if i run the form i can retrive the data but i am not getting the data in the grid at first ,there is a "+" sign, i have to clik that then it shows the table name and after clicking the table name i can view the data displays in the grid..
I have tried googling so much that I have given up trying to look. I am trying to display a dataset in a wpf datagrid. After that I am going to need to display the individual column value in textboxes. I can then change the value in those textboxes and pressing, say, a commit button, to commit the changes to a database. Here's the code I have so far.
Dim con As New SqlConnection Dim dbConnString As String Dim ds As New DataSet
How can one search for multiple items at once and display the result in a datagrid? for example, i want to search for multiple mobile numbers (in sql server database)at once and display the found numbers and their corresponding names.
I have the following code that refreshes the datagrid in the form after the update is made to the database. My question is why do I have to clear the datasource and then re-add it to get the changes to display. I would think that the refresh method would do this, but I can't seem to get that to work. Is there a more efficient way to refresh the datagrid rather than resetting the datasource?
Public Sub addPlan(ByVal planname, ByVal plannumber) Dim planinfo As New changeDatabase(planname, plannumber, planAdapter) planinfo.addPlan()
It was written in vb6 and im trying to rewrite it in vb.net. I've completely stripped the program down from all the unneeded fancy addons and now just have the needed code to run it. The program retreives the records, but does not populate these records onto a datagrid.
Heres my Form code (Form1) Imports ADS_SQL_TEST_VBNET Public Class Form1 Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]...
I think the problem lies within the LoadDataBound() Sub routine, but I can't say for sure since I was unable to fix this myself.
I am reading a xml file and display all the data in datagrid view. But when I chose to display data of just one column only the data comes in the dgv but no column header. Same problem shows up, if I chose to display a particular row of a particular column. How can I fix this ??
I have a form with a datagrid, few buttons, and textboxes. I can add the new record in data table and can display in datagrid. The problem is that... the new record which i have inserted in data table is been displayed at the last row of datagrid which i am having trouble finding it out whether the data is been inserted or not.
1. my question is how to display new record / row inserted in datagrid at the first, so that i can see the data is been added.
2. how to display numbers of record which i have seleted in data grid e.g. 1 of 20 when i select first row and 2 of 20 when i select second row. i can display only total number of records of datagrid.
I have created a form that allows me to search customers from a datagrid table which holds the information from the customers table. I use a textbox to enter the phrase to search for and a search button. I can find the records within the datagrid table but it only selects them. I want the datagrid to only display the records found.[code]...
im using this code to display records in a datagrid.. DataGrid1.DataSource = mycls.ShowData mycls.Showdata is a function that in a class that i used to display data.. what i want is to create a progress bar that indicates the actual loading of the data to the grid.. cause it has some delay in displaying if data is to large..
I have Search form where I display the searched content on a datagrid. What I want is to display the content that I have on the datagrid on a crystal report.
