View 6 RepliesI have a Data Table Column with multiple Rows of data. I need to search all lines of TextBox1.Text for any data that is identical to any row in the specified data column ("MCaddRG"). Also any identical findings need to be made into a new text file or a new form with a text box.[code]...
*Also if it is possible I would really like to have a check box list that contains the data from the "Device" columns so I could check the "Device" and then it search the TextBox.Text for the checked "Device's" "MCaddRG"

In my form there is a Data Grid. When the datagrid is populated, I like to display the total number of records in the grid and sum of a particular column of the grid. Is there any method to be invoked?
What could be the code if I want to add the value in the 1st row and 2nd row. I want the total to be displayed in Label1.text. I'm just a beginner in Datagridview.Anyway, I didn't put the code because this is just a very small portion of the program that I am creating.

View 4 RepliesI want to know if it is possible that the data grid view (DGV) rows dont stat at the top of the DGV, but start at the bottom. When I select de DGV it comes by default with the first row at the top, just below the column header, when I add a new row, it comes below the first row. But I want the first row at the bottom. And if I want to add a new row, it will come above the first row.
View 2 RepliesI have a databound datagridview.I have disabled automatically adding new rows to the grid. The datagridview is bound to a datatable.In it,I have also set the Protected Overloads Overrides Function ProcessCmdKeyto handle and process the 'Enter' keypress.When the user presses Enter within the Datagridview,I want the grid to add a new single row to the bottom of the grid.I have tried several methods to do so,but the grid always adds the new row to the top of the grid instead of to the bottom.I tried posting this issue in the Windows Forms Data Controls and DataBinding board, but didn't recieve any help there, that's why I'm posting this here instead.The only person to help me there said she couldn't reproduce my issue, even when I supplied her with the exact code I was using.I believe there is more than one way to implement this adding of a new row to a datagridview programatically, and browsing through the various msdn forums, I came across several and tried implementing them all, always with the same result.I don't remember all the various implementations I have tried, but here are my few most recent ones:(This is within a class I created that inherits the datagridview. This custom class was the only place I could specify the ProcessCmdKey function, it doesn't work in an instance of the datagridview instantiated directly onto a form. That is why I'm using the me keyword to refer to the datagridview)#1)

Have you design a program that the user choose which material and a number of students in this article and the class and a number of students in grade
For example, if the number of students in Grade 10 students
The number of students selected for the Article 10 The English language program to include material in a cell alone < English >
Though the number of selected students of history 5 and the number of students selected for geography 5 The program develops articles on each Some
History
Geography
To signify that we have five students who went to the study of history goes the rest in the same proportion to the study of geography
how can I do that as it is in the first image attached to you my sincere

Let's say I have ten rows on a data grid and I have changed data of three rows.
I am trying to save data by Linq for those three rows, but I am not sure how it is possible to save them.
I can do it by looping whole rows by checking each row for any change.
Is there any smarter way rather than looping by code, such as For Next.

View 6 RepliesI am almost there but for some reason I don't find the answer to my issue. Here it goes. In my application I have a form which displays a data grid view with some info I get through XML from a web server. The data grid view have as first column a Check Box colum. The second column have the information I get into a variable (from cells), one by one, to pass it to the sub with the XML command.
What I want to do is to be able to select all the rows and send the cell info of the second row (only for the selected rows) to my sub which will execute once then send the second cell info and execute the sub and so on until all the loop is complete. Currently my code works only if I delete one row at a time (sending the XML code will delete the info in the web server and update the datagridview which in return will remove the item).

View 1 Repliesi have datagridview populated with stock code, name and description.And i have docked my datagridview to the bottom. so whenever the form is resized, the bottom section will be occupied completely with the datagridview.But i want to display one extra empty column and multiple empty rows to completely fill in the datagridview.The extra empty column width will be adjusted to the right end side of datagridview.And the no of empty rows will be generated based on how many is required to fill up to the bottomSo that i can create datagridview with full column and row even though some columns or rows are empty.
View 1 RepliesI've got a table in an SQL server that often has large amounts of data imported into it via an automated process - the problem is that a lot of the data that gets imported is a duplicate of data that is already in there (for example if we have a customer in there called Mr Customer Ltd, a duplicate with a slightly different name could get imported, like Mr.Customer Ltd).
So I am using the Fuzzy Logic class that Wild Bill put in the CodeBank to find names that are similar and then highlight these items. The thing is that the target table that the imported data ends up in has several thousand rows and the table that contains the data to be imported often contains several thousand rows as well, so I'm trying to decide how to do this. Obviously reading both tables into memory is not an option as it will consume too much memory on the client PC that is running this app. So this is what I am doing at the moment:
1. Read the table that contains data to be imported into a DataTable in memory
2. Open a connection to the target table and use the SQLDataReader to start to loop through it
3. In this loop, for each row that the data reader reads I then loop through the entire set of rows in the DataTable and run this fuzzy logic method that compares the account name from the current row in the datatable loop to the account name in the row that the datareader is currently on.(there is also a Thread.Sleep(1) after each row is processed to prevent the process from eating up 100% of the CPU while it runs)
After creating a multi-table SQL View in a dataset and trying to configure it, the vizard refuses to create UPDATE, INSERT, DELETE statements or Update method. Does that mean that Views altered by VB code cannot be written back into the database? I am having trouble finding good basic information about SQL Views handled from VB.

This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

I'm a bit confused as to how I should go around approaching this? Btw, would this classify as MDI?We were recommended to create a menu system that listed all the options - upon selecting an option, a new window would be opened, the interaction would take place. If the user wanted to do something else, he'll close the window to be taken back to the menu screen.
This doesn't really seem like an elegant approach to me and it seems like it'll be an interesting exercise to implement the tab-based system I explained.I'd appreciate if anyone could point me in the right directions or give any hints as to how I should achieve. Is it possible, for example, to create each option in a separate xaml/code-behind file and then 'plug' these into each tab?edit: To clarify, let's take a hypothetical of an indoor soccer team management system. Let's say there are five different tasks the user can perform: 'Register a player', 'Modify players', 'Register a team', 'Modify team details', 'Add player to team'.
Each task is separate from the next. One way of creating the application is to create a main page with a button for each task. When a user click on each button, a new window opens up (for example, if the user clicks 'Register a player', a new PlayerRegistration window is opened).
What I'm looking for, as mentioned above, is a tab-based approach. In my application, if the user clicks 'Register a player' the entire PlayerRegistration xaml file gets loaded in a segment of the window. The same happens when the user clicks any other button.
