I'm a intermediate vb programer and I need some help basically I'm trying to get the first five rows in the data grid and create a print document then take the next five and do the same thing until there's nothing left in the data grid.
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.
I have a DatagridView control. I have 4 columns. What I want to do is allow the user to add rows and enter data into the grid and then click a button and save the data in the Gridview to a table. I can't find any information on how to do this
I 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.
when i run this code it said not possible to invisible rows but i just want to see first 5 rows how can I do it?? If DataGridView1.Rows.Count < 6 Then For i = 0 To DataGridView1.Rows.Count - 1 DataGridView1.Rows(i).Visible = True Next
Let me know if I use the wrong words when discribing my situation, I am a student in college learning VB. I have a a datagrid bound to a table built in sql server 2008. The search feature works like a charm but I want to display a messagebox error if no rows match the search criteria. Here is the code I have come up with:
I am trying to make an address book and need help. I am in the middle of making a search function for the program and I've got that working fine. What I would like to do is take the row that is selected from the search results and make that the selected entry for the main form. To explain what I mean I will include pics..
I 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).
I have data grid view with checkbox as unbound column and a button at the bottom and when button is clicked i want to check all rows in the datagrid view i.e check the checkbox if it is not checked for all rows in datagridview. If button is clicked again i want to uncheck the checkbox for all rows if the check box is checked.
I have a grid containing rows flagged with different priorities. I want to color the high priority rows red, low ones blue, etc. I'd like to set the shade based on a mathmatically calculated gradient rather than arbitrarily assigning colors to specific priorities. How can I extract a single color from a single point along gradient?
There are few steps to find out the half slopes of the graph.
Step 1: Rank the data The independent variable is required to rank it from the lowest to the highest.
Step 2: Divide the data Divide the sample size into 3 roughly equal parts, which is the lowest, middle and the highest parts. If n/3 has remainder of 1, +1 into the middle part. If n/3 has remainder of 2, +1 into the lower part.
Step 3: Find the median The size of each part = n, find the ((n+1)/2)^th value for both dependent and independent variables. If the ((n+1)/2)^th is not an integer, sum up the 〖n/2〗^th value and ((n+2)/2)^th value and divide the total by 2 to make it as median. The median, m1 for independent variable in lower part indicate as XL , middle part median, m2 as XM and the highest part median m3 as XH. For the dependent variable the median is indicate as YL, middle part as YM and the highest part as YH . Figure 3.2 Example of median m1, m2 and m3
Step 4: Find the half slope Find the half slope for the lower half, b_L=(Y_M-Y_L)/(X_M-X_L ) and for the upper half, b_H=(Y_H-Y_M)/(X_H-X_M ) .
Step 5: Find the half slope ratio, b_0=b_L/b_H . If the ratio is negative, the dependent variable need to add with a constant, c in order to make the slope same direction.
Step 6: Identify transformation. Depend on the graph pattern pick one type of transformation which is nearest to the original of the variable.
Step 7: New half slope Find out the new half slope ratio, b1 by repeat step 4 and 5 with the transformed variable.
Step 8: Repeats steps Repeat step 6 and 7 with choose the transformation which is nearest to previous transformation and find the new half slope ratio, b2, b3,�, bn. Repeating this step until |1-b_i |≤|1-b_j |, for i<j, i and j = 1,2,3,
Step 9: Result bi is chosen. The data transformation used in bi is the most closest to be normality.
How to make it into visual basic and let it run by the program?
i 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.
This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?
I want to compare rows of two grid views.GW1 and GW2.When I click a Search Button ,I want to check the Values in the GW2,and if GW1 and GW2 have same PayID ,EmpID,then that specific row of GW1 must be disabled.
I 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)
If keyData = Keys.Enter ThenMe.Rows.Insert(Me.RowCount(), 1)Return TrueEnd IfReturn MyBase.ProcessCmdKey(msg, keyData)
i need to get 2 dates and then add rows in a grid for that many months. e.g. the user gives 1st Jan 06 as first date and 30th Dec 2010 as second Date the rows should b

dont know why but am totally puzzled as to how to start with it....
I have the below code that i am trying to have two datagrids with a grid splityter in the middle. The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking? <Grid x:Name="gdHistory" Grid.Column="0" Grid.Row="2" > <Grid.RowDefinitions>
I have a problem with importing an excel into a data grid.
Here is my code:
Try Dim _Obj As New ExcelConnection.ExcelConnection _Obj.ImportAttendence("c:Info_pc.xls", DataGrid1) Catch ex As Exception
End Try
In the excel i have numers and text and "Service Pack", "Processor Speed" and "Numar procesoare(Number of processors)" and the values for these are numers. in the data grid when i import the excel those values doesn't appear, i receive the value "null".
I have 1 datagridview and i want to transfer all records to another datagridview, how can i possibly do that. Newbie here. This is my code in transferring 1 record to another datagridview to another one.
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.
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."
I just want to display data in a DataGridView (from SQL - already made the connection) based on what is selected in a ComboBox (data that is also coming from SQL). The 2 are separete on the form. I am using VB 2010.
This doesn't work for me: objCommand2.CommandText = "SELECT ProductID, Name, Color, Size, ListPrice FROM SalesLT.Product WHERE ProductCategoryID = " & cbCategory.SelectedValue
