DataGridView - Remove The Check Box For Only Some Rows?
May 10, 2012
How to remove the Check Box for only some rows? Anybody can share the code for that? See the pic. I need to remove the check boxes for alternate rows. I dont need for Row 1, Row 3, Row 5.
My datagridview is bound to a data table. I want to filter the datagridview without affecting data table. I know one way is to use bindingsource, but binding source will use column names in its filter. But I want to enable users to enter any string in a textbox to filter. So I pass datagridview by reference to a function PassFilter which removes unwanted rows in datagridview. I can see that it does execute rows removal in datagridview. But the problem is that when datagridview is shown on the form, it is unchanged, the same as the data table. I do not understand why rows are not removed on datagridview The code is as follows:

The code is as follows:
DataGridView1.DataSource = table PassFilter(DataGridView1, m_FilterQuick.strFilter.ToLower()) Private Sub PassFilter(ByRef datagridview As DataGridView, ByVal strFilter As String)
how do I do that? Here is what I have below and I want to remove all the rows from the datagridview?
Dim dataGridViewNetworkDevices As DataGridView For i As Integer = 0 To dataGridViewNetworkDevices.Rows.Count - 1 dataGridViewNetworkDevices.Rows[i].Remove?? Next
Private Sub btnDelProfileURL_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelProfileURL.Click Dim Count = (dgvProfileURLs.SelectedRows.Count) MsgBox(Count)
[code]....
This code seems right but its not working. It's giving me an "Index out of range" error. If I change the upper bound of the loop to "(Count - 2)" the code works, it just deletes all except 1 selected row. So can't figure out why "(Count - 1)" doesn't work.
how to remove the selected rows from the DGV control
My grid is having as check box colum, if the check box is checked then i want to delete such rows i am having a piece of code, but is not working, i mean one row is getting left
vb.net Dim Drow As DataGridViewRow Dim iX As Int16 = 0
I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click 'Function declarations

how to add Rows programmatically to the DataGridView's rows collection when the control is data-bound? here is my code but i got error as "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound? "
I have a simple application that uses a database to store usernames and passwords.I have a hidden control that, when activated,should clear all usernames and passwords from the datatable.Then, one admin account is added. I have tried the datatable.clear method BUT while it throws no errors, it doesn't clear the datatable.I have also tried the datatable.reset method, with the same problem. I am now trying this method:
Dim row As DataRow For Each row In Authenticate.Logins row.Delete()[code]....
I have the following code in which it supposed to remove rows that have the first column checkboxes checked, but it only removes one row at a time.If you have more than one checkbox checked, you have to click the command button each time to remove the row.It seems that the logic is correct to remove multiple rows if more than one checkbox is checked, but it doesn't work.
Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click For Each row As DataGridViewRow In DataGridView1.Rows
I am new using Jquery. I am using vb.net 2008, and I have built a gridview and populated it with data. I am trying to use jquery to go in and remove rows if one of the attributes of the row does not equal the user that I am currently looking at.
_CheckPayees is a DataTable variable. After it is set with the code above, I would like to go through it and remove duplicate rows from it. These rows have to be exactly dupes though, say two columns have matching values however another one doesn't, that's not considered a dupe.
Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.
It was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2 Column3 Column4 1 1
[Code].....
What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.
I have several problems with rows in a DataGridView. Background information: The DataGridView (DataGridViewCalib) is in one TabPage of a TabControl, some columns of the DataGridView are automatically DataGridViewCheckBoxColumn as the DataSource have some colums which are Boolean. This is a Windows Form written in VB.Net with Visual Studio 2008. The user loads an input data file.
The problems:
1) At first arrival in the TabPage, ShowDataGridViewCalib (code below) is called. All rows are then shown in the DataGridView, despite the code saying that some rows should not be visible. Breakpoints in the code show that the code do arrive at the Rows.Visible = False events. Despite all rows beeing shown a Watch in the debugger shows that:

There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".
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 have 2 forms, each one with a datagridview.I want to transfer all the DataGridView Rows from From2 to another DataGridView of Form1. but it's not possible.
I have this problem with this macro. I think it's a VERY common problem, but I just kind find a straight answer since it's so specific.
I have data like this: juanA50 juanB60 juanD70 pedroA50 pedroC70 pedroD80 pedroF90 felipeA50 felipeH100 felipeL200
The first column is the name of the employee. The second one contains the name of payment concepts (salaries, insurance, etc). The third column contains the actual amount to be charged or discharged.
The desired output should be like this: ___A_B_C_D_E_F_H_L juan_50_60__70___ pedro_50__70_80__90__ felipe_50____100_200
Delete duplicated values in the names, merge the matching rows of an employee and put them in the correct colum that matches the payment concept. I'm using SQL Server 2000 and Excel 2007, so feel free to talk about querys and Excel 2007 new functions. This is done with a VB6 application (not VBA), so I'm using Excel's object model as a reference in my project. I was originally trying to do it with SQL Server, instead with a macro, but I couldn't find a way.
How can I write a loop to run for each day in the current month and then check to see if the Dataset has a record that matches one of those days and take an action?
For Day As Integer = 1 To DaysInTheMonth For Each row In MyRows If row.Date.Day = Day Then[code]....
This generates too many rows in the table I have it building. Basically, every day gets as many rows as there are that contain data.I'm building a HTML table that gets mapped into a chart using jquery so I need a for everyday of the month.
I have a text file with some call records in it. Each call record states a line in that text file. And what I want to do is that parsing to database with a 100% success rate. Due to sometimes the SQL connection might get buggy or stop or w/e so it came to my mind that I should make some function or maybe a stored procedure to check whether the requested/selected or whole lines in that text file have been successfully added or not to the database. Let's assume I have 10 lines in a text file called "log.txt" like:
call line 1 call line 2 call line 3 call line 4
[code]....
And assuming that the SQL connection to the database got stuck somehow(buggy) and it stopped inserting those lines to their respectively columns. Let's say it parsed lines from 1-6 and it stopped there, that's where I need the app to tell me that it stopped and continue inserting immediately where it stopped at to the end from 6-10th line. What am I supposed to do? The smoothest way so that the processor doesn't get overwhelmed (in case there are like hundreds of thousands lines). And should it be written in SQL as a stored procedure or written as a function from VB side.Toolkit : Microsoft Visual Studio 2010 Ultimate - VB.Net language & Microsoft SQL Management Studio 2005 - SQL Database.
