Populate Data From Dataset And Show In Datagridview
Aug 11, 2009
I am working in vb.net and i have a simple requirement. I have added a MDB file to a dataset and it contains 21 tables. I have a datagridview and a combobox on my form. I was able to get the combobox populated with the table names available in the dataset by iterating through dataset.tables. Now i want to add the feature where the user can select the table name from the combo and then it should populate the contents of that table. I tried the following Code
I have written my and in a test class for vb.net and it works as follows:
A stored procedure is executed and the result is saved in an xml file with the help of a dataset. What I need to do now is , Information of this dataset should also be redirected to a textbox in a form so that I can copy this information in clipboard and create dynamic assert statements for instance I want
How do I loop through a dataset and populate a DataGridView - heres my code. Hopefully someone can point out where Im going wrong... Not getting a specific error, just failed message box. when i take out the try/catch function then Im given no error but the DataGridView does not populate.
I have a simple access database that a log record gets written to a few times an hour.
I'm trying to make a DataGridView that shows that data as it arrives.
My "Solution" is simple;
when a user clicks the view -> read from the database (fill the datatable) -> update the view.
Not what I dreamed of, but functional, if totally sub-optimal.
However, my "solution" is a dud, using fill draws every single record from the database, even if there are already 599 on screen.
Really, I just want fill the datatable once, and add new records as they arrive (or on click if needs be).
Bonus point if you can also explain another way (that isn't called so often) to hide the ID column, and change the header of column 1 (named DateTimeStamp) to TimeStamp.

I am attempting to discover how I can populate a ComboBox with the data values already located in a data source that has been added to my project. I know how to use the ComboBox.Add method. I also know how to add individual value items contained in a manually entered array at design time using the For Each Next loop. However, I am unable to populate a ComboBox with all values for a field of a table in a data source that has been added to my project. I assume that I am unaware of some simple referencing step that will solve this problem.
I have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String) Try TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.
Im new to vb.net and would like to know the very basics on how a datagridview works? how does it populate data from the database? what process does vb follow to update this datagridview? I'm trying to get my head around the following terms and need some explaining how they work and how they are linked? if possible, is there a link to a diagram that explains this?
For some reasons I'm getting no data populating in my crystal report. I have set the datasourse of my crystal report to the dataset. I filled my dataset with data straight from the database. My dataset is not empty, I always check it first before populating data to the my report. I built my crystal report off the wzard and I did add
I have a form that lists all of the clients in a DataGridView and when I click on a column that is a Link I want the data to populate into the form I use to capture. My problem is that when I click on the link all the TextBoxes on the form are filled correctly but my ComboBoxes are not.[code]

is there a way to make this less in code?Usually when im going to populate a datagridview with data I usually do in this way
[code]...
That how I make things harder although there's a function "DataGridView1.DataSource = myDataTable" and put an sql where selecting those data. I just want to use some other method. so how am I able to add some columns row dynamically and if another column of the database need to get how am I able to add it in that loop is there other way and I want the less code nor the shorter code that you can give to me. I just want to learn and make my code more shorter
I have made DataGridView in the designers and connected an Access database to the datagridvies and the Column headers appear as they should and when I check in preview mode all the fields are correctly populated. However, the DataGrid is not populated in normal mode at all. I have been trying to run the project but nothing is happening. What can I do to populate the field.
fill a NEW DataSet's DataTable with data from a DataGridView? I am generating a data report that uses that "new DataSet." I need to go from a DataGridView to a DataSet because i need the person to be able to perhaps edit the information before its inserted into the report. my process to generate the report is...
- fill datagridview with advanced join sql - allow user to edit datagrid if necessary - put datagrids modified information in new dataset - set report's databinding source to new dataset - generate report...
i am trying to get data from the clipboard into dataset and view it on a datagridview using the code below.

I am trying to produce a form in VB2008 which shows data from two related database tables, and then allows the data in one of the tables to be updated. I would like to do this using a DataGridView, but I have no idea how I would go about this.
I have a datagridview.And as per my requirement the data is supposed to be filled from three different tables in database.I have created the query and is succesfully able to populated the data in it with the cross join.Have a look at my structure.
Table1,Table2,Table3. table1 has 2 records. Table2 has 7 records. and Table 3 has 15 records.
Below is my code that reads data from Cross Join Query
If dr.HasRows Then While dr.Read combo1.Items.Add(dr(0))
how the various elements that help you handle errors work together. Have tried several options and can't make head nor tail of it. The underlying table has two columns, an autoincrement integer and a text column with the following settings:
I need to get a table on my Form that has different columns from differen tables.As I call many tables by their Identity ID, I also need a way to show the information from that table.I created a query in my TableAdapter which selects information from 2 different tables. Tested it in the query builder and all was OK.I tried to put an empty DataGridView onto my Form and inserted the correct BindingSource for my Data Source.I then added a query and selected the query I created in my TableAdapter.
I am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for.Is there a way to edit columns and rows manually ?This is a list of what i want to do :
1. First of all i want to change column captions. because they are like "Fld_name" etc.
2. There is a column that shows date. I want to write a code for it ( convert date type )
3. I want to add a button at the end of each row and write a code for it ( show detail about that record )
I have a user control that contains a search value text box a button, and a datagridview to display what the data adapter found. In the data set designer, I have an ODBC connection to a table, with two SQL queries defined FillByCustomerName(NAME), and FillByCustomerNumber(CUSTOMER_NUMBER). If I preview the data in the designer, I see the data expected. The datagridview doesn't show any data. The functions PopulateGridByName and PopulateGridByNumber do the work. I've tried adding a dgCustomer.show statement, The form that calls the user control has no codebehind code, and throws no errors.
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click Try Dim SearchValue As String = CreateSearchValue()
