DataGridView Multiple Row Selection, Specific Column Data Get?
Apr 23, 2012
So I have a datagridview being populated with data from a database.At this point a user may or may not selected (via mouse click / key press) one or more rows within the datagridview.I need to (upon selection) create a new dataset, datatable and add rows with the some data from the said datagridview.
For example, if a table had nothing but names, e.g.
Upon the user clicking, dragging a selection over Sean and Larry to add those names to a new dataset so I can pass it to another method for further processing.
Input array is longer than the number of columns in this table.It looks like I'm either missing a column declaration or adding the table to the set?
Iv've always done a loop like below to go through each row of my DataGridView..For Each row As DataGridViewRow In DataGridView1.Rows....Is there a way to specif a specific row and column that i want to get data from? I tried this below but didnt work
MessageBox.Show(dataGridView1.Rows.Cells.value) and MessageBox.Show(dataGridView1[0, 1].Value)
Am using vb.net 08 and i have a datagridview with 3 columns. The first column has a button as the columntype with the name "UserName". Now, i want if the user clicks only on the UserName which is the first column, but not the entire row, it should display the value of the UserName column only. If other columns are clicked are apart from the UserName, nothing should display. So there will be a for loop that will itera te through all the rows of the datagridview.
I have been looking all over the place trying to figure out how I can programally select a certain Cell in a row. What I am attempting to do is when doing Rowvalidating, and I find that the user has not filled out a column, I do a msgbox, then want to have the cell have the focus, so user can enter in the data. IE, like the way you can cause a text box to have the focus.
I can't for the life of me remember what that first(non column) is called.. its where you it has the right pointer or where it has the * for a new row. Anyways... I don't want to see it.. and want to remove or hide it from the datagridview I am working with...
What is that column called? and how can it be removed or hiden?
In VB.NET 2008 I've two forms 1 & 2 containing two datagridviews connected to two data source 'ACCESS 2007 tables' Now I want to select multiple rows from one datagridview (form1) & transferring these to another empty datagridview (form2) with a button_click.
I am using a list<of T> as a data source for a datagridview and would like to handle the draw event of the datagridview to evaluate the string length of the column cell. If larger than a particular number then I would just do something like
cell.value = string.substring(0,(whatever number I need it to be)).
how to convert a string that is entered in a column to proper or title case. For example, user enters "now is the time". Code will capitalize the first letter of each word "Now Is The Time". In VBA I would execute the following code in the afterupdate event: me.fieldname = strconv(me.fieldname, vbProperCase).
I have on my form a combobox, a datetimepicker, a button and a unbound datagridview. The datagrigview is fild with data like a yearcalender.So i have in first column all dates of januari, then a blanc column, then the dates of februari, then a blanc column and so on...This is wat the user will do :
select his name from the combobox, select a date from the datetimepicker and press the button.What i would like to happen then is this : Find in the datagridview the same date as the selected one and then place the selected name in the blanc cell next to that date.
NB: I'm using Visual Basic.NET?My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid.When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid.So, basically, I want to dynamically display data in one grid based on user selection in another grid.My code looks like this so far...
Private Sub RulesGrid_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles RulesGrid.CellClick Try FlagsGrid.Visible = True
I'm trying to sort multple colums in the DataGridView which is unbound. I would prefer to sort by using a DataTable/DataView but for some reason another developer in my team experienced other problems relating to sorting so he abandoned using the DataTable to fill the grid :(
Here is the senario: I want the user to be able to choose which columns they want sort on. The way I envisaged was to show a form with a listbox, a grid and 3 buttons (Add to sort, Remove from sort and Apply Sort).
The list box would be populated from the parent form grid column headings. The grid will show the columns and sort direction. Button 1 would add the selected item of the list box to the grid. Button 2 would remove from the grid the selected row. Button 3 would Apply the Sort in the order of the grid and the columns SortDirection.
Now I looked at How to: Customize Sorting in the Windows Forms DataGridView Control using the IComparer [URL]
how I can use the IComparer to sort on multiple columns that a user has specified or another way to sort on multiple columns using unbound data.
I know this has to be a very simple answer but I seem to be overlooking it. I have an Access database that I have conected to and have created a DataSet. The DataSet consists of one table with several rows and a bunch of columns. What I am trying to do is get the data for one specific row and column so that I can use this data is some calculations. I can position the row if I need to but I can't figure out how to get the data in the specific column I need.
get specific data from below case?. As it is imported from text file, all row data located at A column per Row and total number of rows are more than 30000. From below, I want to get Company name and Address data only out of long text data.
For your understanding, a)Each row start with 6digits number like 3336041, 3336058 etc and end with pin code 6digits. b) there are minimum 4 or more digit's space after company name and each address data.
Result should be got <company name> and <Address field> data only.
for example 1st block should have below format;
PROCON INSTRUMENTATION PRIVATE LTD
244, G S T ROAD, URAPAKKAM,GUDUVANCHERY TAMILNADU, TAMIL NADU Pin:603202
2nd block: to display in another lines as like above - marked as bold in sample text
3rd block: to display in another lines as like above - marked as bold in sample text
I have a gridview loaded with data from my database and a gridview swapping function which after exchanging data between rows with a column call "Priority", I want to save these changes back to my database. Only the "Priority" column value will be change, how do I update only that Column of my dataset table to my SQL database?
I'm somewhat of a novice at VB.I have a DataGrid that I am manually populating from a SQL query-based dataset (see code below). Question: How do a capture the value of a specific column of the selected row (mouse click in the row) to use as a variable in other parts of the overall solution?Also, how do I add cell padding around the contents of the data grid cells?
Two quick questions about datagridviews... I have an unbound dgv and I'm trying to do some simple formatting but sadly my .net knowledge is limited at best. I'm trying to make a balance sheet and I need to do two things:
1. How can I set row(d) to sum row(a:c) for each column (for multiple years of financials)
2. Is there anyway to not only make a row readonly, but make in unselectable (to skip totaled rows)?
I'm trying to write a program that will take emails that I have saved from outlook as text files and scan it for specific data, and return those strings to a textbox (i will modify it so it outputs the exact way i need it, i just need to grab that info faster than it takes by hand). I dont know how to go about actually grabbing that specific data.

There can be only one grouping (denoted with asterisks, they are separated in the emails like that as well), or 50 and any number in between. I only need the information as shown in the text file example above (sometimes, it is blank or not there - if that's the case just skip and messagebox.show to alert me that it was skipped).
I am trying have a data grid selection populate a form. I am new to this.Basically I have a connection persistance object and I would like to call that and call a stored procedure with the value of the selection. The datagrid is bound to an object.
I am trying to fill a label with data, using datagridview, from a specific row, cell. The commented out code works but is tedious and sequential, basically has to go row by row. Is there a way I can just say "hey, gimmee the data at x,y?" LOL Trust me, at one point I even tried that. All this must take place at form load so there is no click events involved.

I have created a Datagridview with 4 Columns, EJ: ID, Name, Quantity, other..But i want to fill these 3 Columns from MySQL EJ:[code]but this creates new columns and does not write to the existing, took a while looking for a solution but only find methods like this.
I have a data grid view that contains several columns. The first column is the only column I care about and it contains Result IDs. The view may be filter from time to time. I want to get the Result IDs from all the visible rows and put them into a table variable so I can use ADO.Net to send that table to a SQL Server stored procedure. I currently use a loop (see below). Is there a way to do this quicker without a loop? I'm new to VB.Net and I was hoping .Net would have an impressive method to do the same thing the loop below is doing.

I'm having problems editing the text of a particular column in a datagridview from the front end. The text enters ok but as soon as the cell loses focus it goes back to the old value. The datagrid view readonly property is set to false and I don't have any problem writing to the other columns.
