TabControl With Tab Pages In Form - Refresh DataGridView
Sep 2, 2010
I have a project with a form in which I have a tabcontrol with several tab pages. In each tabpage I have a datagridview and some textboxes and some comboboxes. I managed to refresh one datagridview but it stopped working. - I don't know why. Here's what I did:
Public Sub RefreshGRD()
Me.Adapter.Fill(Me.DataSet,"table")
End SUb
And I called this fnction before closing the connection for each button that adds or deletes or updates. Before calling it I cleared the dataset.
I have two Tab pages like Customer and Employee in TabControl. ( VB.NET )
I am setting with the shortcut like &Customer , &Employee . But in the run time "C" in the Customer tab and E in Employee tab is not showing as underlined text.
I have a usercontrol which has a number of labels on it. The usercontrol acts a bit like a listbox but I can control the background and foreground color of the labels it contains - nothing fancy use it for logging a process - a bit like a scrolling console window.I have a form with 3 of these controls, Progress, Errors, and a debug logger. Works fine when placed on a form until I add a tab control with three paces and place each usercontrol on a tabpage. then random labels are not updated.
Problem: My datagridview is moving from a tabcontrol onto the main form when I execute the below code. I desire it to stay in the original position. Details:
1) I created a MAIN datagridview1 for my master on tab 2 (OK) - this is for editing, deleting etc.
2) I created datagridview3 on tab 1 for implementing 2 textbox filters (OK)
3) The actual filter code fires on changing of values in two text boxes
The above works perfect except when the code below is executed, datagridview3 moves from tab1 of my tabcontrol to my main form. How do I keep it from moving (desired) or at the least move it back to control tab 1?
My boss has given me an asp.net web application that was done by his former employee. Now my boss has no contact with that employee. He wants me to make some changes in that web application. I went through the application. There is no documentation present for that application . Its a huge application. It contains many directories. I think it was a team work. It has many asp pages, aspx pages, jsp pages, xml pages, css pages, etc... How to understand other person or team's website or web application that was written in asp or asp.net and vb or vb.net?
I need to add forms to TabPages in TabControl, but I need to find bindings between a TabControl and TabPage, that means i want to add a Form to a TabPage which is connected to TabControl1.
I have a Tabcontrol populated with pages tab1 tab2 tab3.What i want to do is if a user begins a function in lets say tab2, it wont let them select another tab until either the function is complete or function is cancelled.so to complete the function designed on tab2, i have but_edit to begin the editing (this is where the tab selection would be disabled), and i have a button set as But_Save, this would save changes let them select a different tab again.
So far i've managed to control this with tab1.enabled = true/false etc, but this doesnt produce the result i want, i want them locked to the tab until But_Save or But_Cancel is pressed.
I am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters.
Here is the code that calls the sub form.
Code:
where ds is the dataset to fill the datagridview and rb is the string from a radio button on this form.
Here is the code in the sub form.
Code:
Now, I need to refresh this sub form every -- minutes, depending on how the user wants it to be. For this I have given a NumericUpDown control to select the mins. All this works fine. But how do I refresh the dataset and the datagridview?
For some reason my tab pages won't update their data when I change the data contained in them. I have to scroll to the next Company and then scroll back for the changes to be reflected in that particular tab. I have no clue why this is as when I walk through my code in debugging, it shows that the appropriate labels are being set the appropriate values. But if I have one of the tabs as the one in focus when I change my company, it is updated correctly.
I have a form on a .NET webserver using aspx pages with the vb code-behind pages. The form collects the entered data and then emails it, that part works fine.Right after it gets emailed, this code checks to see if the email was sent or not and then updates the landing page accordingly. I used to use just an IF THEN statement, but now that doesn't work in these new .NET pages. Here's the end of the code that I am having difficulties with:
Lets say i label "label1" , and 2 buttons named "button1" and "btnRefresh " [code]So , when user press the button 1 , the text will change. But what should i put inside btnRefresh to reload the forms ? and display the default label.text = "Form Load" ???
I have an tabcontrol which has dynamically added the tabpages now i want to add datagridview controls in each tab pages how i can do this.I am written the code like
For i = TabControl1.TabPages.Count - 1 To 0 Step -1 Dim dtg As New DataGridView TabControl1.TabPages(i).Controls.Add(dtg)
I have a form where the user will choose multiple clients from a subform that has a DGV.Each row has a checkbox indicating that it has been selected.When the user is finished selecting the clients, I need to store the selected clients ID Number, Name, and Program Number either in a temp table or another method to only handle about 30 records.After that part is done, I need to create a new tab for each client which has a UserControl on the tab. I have the new tab thing working but I need to learn to apply the client to the first new tab/user control then create another and so on.
Private Sub frmCaseNts_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
I am not sure whether it is possible or not? need suggestion.I want to display filenames from 2 different folders into 2 different DataGridview controls that are placed in 2 tab pages of TabControl1. Here is the code that I have tried. By running this code, I can able to show the filenames from a folder onto DataGridView1 in Tabpage1 but not in DataGridView2 of tabpage2.
I have a problem refreshing a DataGridView control after Insert or Update. The source code: Get all rows from table in datatable and set to the datasource:
I tried this, but all of my rows dissapeared. [URL]
vb Private Sub BindingNavigatorDeleteItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BindingNavigatorDeleteItem.Click If MsgBox("Are you sure you want to delete selected record(s)?",
Private Sub DataGridView1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick If e.ColumnIndex <> 3 Then Exit Sub
[code]....
I am using the CellClick event to update DB column PaidStatus from Paid to Un-Paid and vice-versa....Once updated i want the updated data to be reflected..i am using DataGridView1.Refresh()....but it does not show the updated data from the DB..i have to close the application and re launch it to see the changes.
I created two tables(FIRSTtable and SECONDtable) in the mysql database and two tables that are related.[code]...
Relations between the two tables using the product_id column with UpdateCascade and DeleteCascade. Both relationships are functioning normally when I try with the sql script. Suppose I delete all product_id in the FIRST table, all existing data in the SECOND table will be deleted.
Both of these tables displayed in datagridview. When I delete all the data in the FIRST table, the all rows in datagridview FIRST table will be deleted, also the data in mysql the FIRST table will be deleted.
I try to open the mysql database, the data are in SECOND Table also deleted, the problem why the view that in the second datagridview, can not be deleted, still keep the previous data? How to refresh datagridview binding in vb.net or C#? [code]...
i use a button to execute the update command for editing the row of the sql table. The row is update when i click the button, but the datagridview is not show the update of that row automatically, so i want to know how to refresh the datagridview when the table is update by just clicking a button.Here is the code below i use for editing the row :
Private Sub editbtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles editbtn.Click If serialnotxt.Text = "" Then MsgBox("please enter the enter serial no and click search")
I am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF
Dim Pages() As Integer Pages = New Integer() {1, 3} PdfManipulation2.AddImageToPage(..., Pages)
Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.
The dataGridView data source is the dgvTableAdapter with this sql statement
SELECT membres.ID, membres.refere_par, bands.titre, membres_1.prenom & ' ' & membres_1.nom AS reference_nom FROM ((bands INNER JOIN membres ON bands.ID = membres.[band]) INNER JOIN membres membres_1 ON membres.refere_par = membres_1.ID)
[Code]....
I know the delete statement works because I saw the changes in the database. If I close the form and reopen it, the dataGridView is up to date.
I have a problem with a datagridview control, when first loaded with existing data it shows the correct rowcount figure.However, I have a function that when invoked triggers an oledbcommand to clear those records from the database (access) and load new ones from a file (excel/text).The oledbcomands work fine, and the gridview refreshes with the new data fine. However, the rowcount after this refresh is always 0, even with records. What I am doing is creating a module for my app that allows the user to specify the column title and types for a file import - and the procedure will read the header row from a txt/csv or excel file automatically.[code]If I just make edits in the datagridview (as in not invoke the above) the rowcount returns properly.If I close and re-open the form the new data appears, and the rowcount property returns fine also, but I don't really want to have to tell the user to close and re-open it before making any changes.I must be missing something on the refresh or with the datatable or adapter side of things.
In a windows form I do have a datagridview. When a user pushes the button, the underlying datasource of the datagridview (a dataview) changes and the new content with new columns is shown. This works fine, only problem is that the header-height differs and that the datagridview does not properly display the smaller headers until I click into the first datarow of the datagridview. Simply using the .refresh()-method of the datagridview after assigning the new datasource does not seem to work.
Here is a little code-snippet showing how I assign a new datasource to the datagridview. Dim view As DataView = myDataTable.DefaultView With Me.MyDataGridView .Columns.Clear() .AutoSize = True .DataSource = view For Each col As DataGridViewColumn In Me.MyDataGridView.Columns col.ReadOnly = True Next ...
I have a subroutine for changing the datagridview's columns' colors on form load.Now, everytime the user change a cell's value, the cell's backcolor is changed.If the user click 'save' the program will call the subroutine for changing color.I got everything working except the part that it will return to the color on load after save. I think I should refresh my datagridview but I don't know how to do this.
How to update a dataset used in a DataGridView? I've added a column to the table (SQL Server) using in the DataGridView but the Refresh on the dataset doesn't work. I would delete it and re-add but I can find no way to delete the dataset either.
I added the following code and the data now shows in the grid but I'm not able to edit the new column in the grid because it is not reflected in the DataSet.[code]....
