View 4 RepliesI'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really). Well, I am adding a history to it and it allows the user to see the last 50 records searched. They get a grid showing the records. This, thus far, works perfectly What I want to do is this: I want to select a record (A cell) in the column 'Dog and have the text of that cell appear in a textbox. This is what I've tried with no success.
HTML
Private Sub HistoryTextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles HistoryTextBox.TextChanged
If ugHistoryButton.ActiveRow.Cells("Dog").Selected = True Then
[code]....
It just doesn't seem to want to transfer over when I select the cell in the 'Dog' column.
I want to populate a listview and leave selected records that are true
I have a DB record which is ID int, desc varchar, selected boolean.
I have tried the code below
LVProducts is a Listview and DS is a dataset
CODE:
I'm using a search code using a textbox then it lists the record on a datagridview if search is successful. After the search, the user could select the record on the dgv in which later on can be edited or deleted. Edit and delete button is disabled when nothing is selected on the record. What I want to know is how to trigger an event to make those buttons to be enabled when a record is selected. By the way my datagridview is connected to my textboxes. My question goes something like this, but this is totally wrong.
dgvStud_CellClick = Nothing then
btnEdit.enabled = true
btnDelete.enabled = true
End If

View 5 RepliesIm having a little trouble setting focus on a row in a datagridview. When a user presses the Enter button in my datagrid, a sub is called and the window is closed. Now next time i display the window, the selected cell has moved one row down. This is because when you press enter in a datagridview it jumps to the next line (wich i really dont want it to do). Now then in my forms shown event i placed the code: Datagrid.rows(0).selected = True Now this highligts the first row when the window is displayed, but when you press the down key, it jumps to the third row, because even though the first row is highlighted, its the second row who has focus (because it jumped their after pressing the enter key) How can i set the focus on a specifik row in the datagridview in vb2005?

How to select Row by givieing cell value in datagridview
View 5 RepliesI'm trying to focus input and fire the editing event on each new row that I add to a DataGridView in my form.[code]...

View 3 RepliesI'm adding a ToolTip to a ListViewItem. However, the ToolTip only shows up when the user hovers over the first cell in the row to which the ToolTip has been applied.[code]Any idea how I can make the ToolTip show up on a specific cell in a row, or even the entire row?
View 1 RepliesI'm looping through rows in a datagridview, and selecting a cell from the 3rd column each time:
Dim customer_name as String
For Each dgvr As DataGridViewRow In myDataGridView.Rows
customer_name= dgvr.Cells(2).Value
'....
next dgvr
However, I'd really like to make it dynamic, in case a new column gets added to the grid, so that I need the 4th column, not the 3rd. I'd like to use the column's header text. So something like...
customer_name= dgvr.Cells("Customer").value
Can this be done?
I could really use some help on this. I have been searching for a solution on the web but haven't been able to find much help.I need to add textboxes to a gridview edit cell, based on the number of rows of text in one of the cells. I have coded the capture of the number of textboxes I need to add.
But I am not sure which Gridview event to add the code, when going into edit mode, to run the loop that will insert additional Textboxes in a specific column of the row selected to edit.
The user sees colA that has text with line vbCRLF's embedded say:
"This is sample text."
"Line2"
"Line3"
My code reads three Carriage Return, Line feeds. So when the user goes into Edit mode I want to provide one text box for each line or more accurately, add two more as one will already exist.
The problem is when I search through a textbox and nothing matches the search query, I accidentally click the column header which is the lastname then the error "Object reference not set to an instance of an object." pops up.
The highlighted part of my code is the text closed in quotation marks.
"If dgvStud.CurrentCell.Selected = Nothing Then"
btnEdit.Enabled = False
btnDelete.Enabled = False
Exit Sub
Else
btnEdit.Enabled = True
btnDelete.Enabled = True
End If
This code is under my dgv cell click event. Here is a screenshot for the column header where I found the error. [URL]
I want to be able to delete records from my database and have this piece of code to do so:
Dim myConnection As SqlConnection
Dim myCommand As SqlCommand
Dim ra As Integer
myConnection = New SqlConnection("connectionstring'")
myConnection.Open()
myCommand = New SqlCommand("DELETE FROM player_table WHERE player_ID = 1", myConnection)
ra = myCommand.ExecuteNonQuery()
MessageBox.Show("Player Deleted")
myConnection.Close()
But I want let the user actually select one of the cells displayed and delete that.
how to properly select a row or cell or whichever from a datagrid so that I can obtain the index value of the row properly. Below is the code.This code does select the row based on what is clicked on.
Private Sub dgAssets_CellMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles dgAssets.CellMouseDown
If e.Button = Windows.Forms.MouseButtons.Right Then
[code]....
Now the only way that I end up with the correct Row index is if I left click the cell or row first, then right click. But using the code to select the row on a right click, for some reason doesn't set the CurrentRow.Index to what is actually selected.
I am making a program which remembers my last selected row in a data table. I have done this by adding a column with a CheckBox, upon CellClick the CheckBox is checked, and upon ellLeave it is unchecked and the new cell is checked, after every action a Update command is run. There will never be more than one row with a checked cell in the DataGridView,however, the data table is in a relationship with other tables, so there may be more checked cells in the data table itself. My problem now is selecting the row with that cell when I open the program and when changing between other data tables and back again.All solutions I found on selecting a specific cell in a DataGridView are referring to index numbers, and in my case I need it to find a data value in a column, I do not know the specific row, only that one row contains the value of True while everything else is False.

How to select one cell and mulitple cells in a table using the webbrowser control. E.g. If the web page (local) that I'm viewing in the webbrowser control has tables present in it. When I click on a cell in the table I want to be able to edit the attributes of the cell like adding an align or a class attribute. I think this is possible without using mshtml which I'm trying to avoid as I can't find much user friendly documentation on it.
The text in the webbrowsercontrol is loaded with the foll:
WebBrowser1.DocumentText = Form1.RichTextBox1.Text
So I am guessing that I need to be able to detect when a cell is selected (<td></td> tag etc) or clicked on and then from that point I can edit the attributes of that specific cell (<td class="jimmy"></td> tag etc).
I have a datagridView,which is filled with the Click of the Button.My Issue is i can see the data only when i select a row.When no row is selected by mouse then its just showing blank cell,whereas data is actually there in the datagridView.I know its something with the color setting from the DatagridView Properties.I have tried and corrected all the cell Style properties related with that DatagridView.And set the Cell Style properties exactly the same as of my other datagridview,which is working fine.
View 1 RepliesI have to pull out particular fields from cells in an HTML table. Using Firebug I was able to get the exact XPath to the cells I need (unfortunately, the cells don't have an id tag). I thought I could use DocumentNode.SelectSingleNode and pass in that path, but it doesn't seem to be working right. What am I doing wrong? Or is there a better approach to this than how I am doing it? Unfortunately, I have no experience with XPath so this is turning out harder than I expected it to be. Here's what I have so far (I know the HTML is particuarly messy, but that's not in my control to change):[code]
