is it possible to add two defferent datatable (single dataset) into datagridview? what I mean?I have a datagridview and one dataset with two datatable. here on the datagridview, I have 3 columns on datagrid as (code, name and unit (combobox)) first two from table 1 and 3rd from table2. there is relation between table1 and 2 (code). so, in combo, I have to fill the unit depents the column1 (code).
View 4 RepliesI have data that I'm taking from an Excel sheet with the ultimate goal of displaying in a DataGridView.
Currently I am just going over the UsedRange of excel data and plugging it into a datagridview. This works fine, but can get bogged down when there 100+ rows of data.
I have also toyed with going from excel into a dataset (using the same wasteful method), and as expected it takes about the same time to load the data. Maybe use the XML from the Excel file?
EDIT:
Some Additional Information:
This is a WinForms application and the user will be picking and loading the excel file at run-time.
EDIT
The Return of Some Additional Information:
The Excel file is located on the user's pc. The general assumption is that they will be loading different files each time they use the application. [not sure if this helps, but might be good to know :)]
Okay so I have a datagridview that is bound to a dataset. I have a column called type is a string char of either C, R, A, or V. The problem is that I want to sort the datagridview rows using that column and do so in the order I just gave so I want rows with C on top and then R and then A and then V. Because these aren't alphabetical, how could I sort the items this way? I did look into the icomparer, but really wasn't able to figure out how that works.
View 4 Repliesmy question is, is there a way to filter records in the dataset and use that records to fill in the datagridview? for example, a datatable (with 3 columns: ID, StudentName, Gender) is filled with list of students. i have two datagrids in the form namely DatagridView1 and Datagridview2. DatagridView1 is where the the list of student where Gender is equal to M and DatagridView2 is where the the list of student where Gender is equal to F.in my current solution, i am using a loop.

is there a way without using a loop?
I have a data bound datagridview where I am allowed to add and delete rows.So a new row is the last row in the grid with the '*'. When a user starts to type in the new row, that row no longer is considered the new row. It is then inserted into a row above the new row (*). The user, however, can press 'Esc' key and this row gets deleted.If the user does not pressed 'Esc' but move the cursor along that row, this row will be permanently there. I have tested this scenario and check the underlying dataset and it registers no changes as in the myDataset.hasChanges=FALSE.If I call myDataAdapter.Update(myDataSet), nothing gets updated. How do I save this row to the database?

I have a datagridview on a form that is bound to a table in a dataset from another class.I use a data adapter to .Fill a table in that dataset and the grid displays the data fine.Works fine.On my form I have a textbox the user can type in that will will pass a parameter to the storedprocedure used to fill this table. So on startup the textbox will have "%" in it. and then the user can type in "F%" and get everything that starts with an "F"
So when that textbox changes I launch an async refresh (.BeginInvoke) to do my refresh. The table gets populated with the reduced number of records (I check ds.table(0).rows.count and it is correct)
But the datagridview then starts throwing datagridview.dataerror events. "System.IndexOutofRangeException : Index # does not have a value".It looks like the dataset is getting filled correctly and not having any issues, but the datagrid is not liking this update. The index out of range error is so common that I'm not finding what I need through searches.

I have a datagridview that was bound using the wizard and all the column created that way. So I haven't done any code to bind the datagridview. It will pull the data from the database and dataset just fine. My problem is when I create a new row it won't update the dataset or database. I have tried different ways that I thought it would work in the code and still haven't found a usable way to do it yet. Or if I need to do all my binding and columns through code give me an idea where to start if I have to go that route. This is my first experiences with Datagridview. I normally use comboboxes and textboxes to write to a dataset and database which all work very well.
View 8 RepliesI am making a combobox from my data source. Basically, This is a projects form and the user needs to select the the primary contact which is contrained by the customer id (GETbyCustomerID) set in another field. I have it working... mostly except the combobox only displays the contact ID which is completely useless to the user. I need to know how to display the First and Last name (both are seperate columns in the table).

I bound my dataset to a datagridview and when I did any changes with the data in it and try to send it to the database (pressing a Button) got the error message:"InvalidOperationException error was handled.Update requires a valid UpdateCommand (or InsertCommand depend on the action)when passed DataRow collection with modified rows."I read the related posts but they didn't solve my problem. (I have primary key in the table and the AllowUserTo... properties are set to True.)My table is very simple:

I add a row to the DataSet using the following code:
Dim NewRow as DataRow
NewRow = gds.Tables("TitleDataSet").NewRow
NewRow("Title") = txtTitle.Text
NewRow("Local_number") = nubLocalnumber.Value
NewRow("Number_suffix") = txtNumberSuffix.Text
etc.
This code executes without errors but the bound DataGridView remains unchanged (without including the new row). Obviously I am doing something wrong or I am omitting a vital command. What do I need to do in order to make the new row appear in the DataGridView? I did not choose to bind the DataGridView directly to the database table because the database is selected by the user at execution time. Instead I bound the DataGridView to the DataSet. I included the command:L
dgvTitle.AllowUserToAddrows = True
but that did not have any effect.
Solved. Was missing the final command:L
gds.Tables("TitleDataSet").Rows.Add(NewRow)

I have a DataGridView bound to a DataView. The DGV is setup for FullRowSelect and is ReadOnly. The first column contains a CheckBox to show that the Row is ready for processing. The user double-clicks on the row and the box is checked in the CellDoubleClick event. This works great.
I have a RadioButton on the page to hide any checked items. This allows the user to only have to look at the work that needs to be done. I use a filter on the DataView to make this happen. At the end of the CellDoubleClick, I call my ApplyFilter method, but the current row still shows up.
I got around this once before by writing some code to see if I needed to move forward or backward a row and also compared if there were any rows available, etc.
It seems to me that this relates to the value not being persisted back to the DataSet until the CurrentRow is changed in the DGV. Is there a way to force this data back into the DataSet without having to programatically change the value directly in the DataSet?

View 5 RepliesI have a DataGridView control in my windows form application. What i want to do is this: I want to reload the view so that it shows the correct data when a change occur to the database table that it is bound. In other words, when i delete a record, using an sql query not the DataGridView1.Rows.Remove(DataGridView1.CurrentRow) property, i want the changes to occur to the datagridview also. For example: I have a customers table that is bound to the datagridview. When i delete a record, lets say the one with ID=5, i want the row to be removed from the gridview in run-time. Is this possible?
