Select Items In Code In A Listbox Bound To A Dataset?

Feb 23, 2011

I have a list box that is bound to a datatable, which works fine. The question I have is this. I have a list of values in the form of a sqlDatareader that I want to use to select values in the list box, that is to say if the value from from the datareader matches the value member from the row in the listbox then select the row. I've come up with the following code, but can't find the syntax to utilize the SetSelected method.[code]...

Bound Untyped Dataset Search And Select

Sep 21, 2009

I have an untyped dataset which is programmatically bound to a form in vb.net 2008. The first record in the dataset is not necessarily the record the user selected to view. I need a way to, after the binding is done, move the dataset to that particular record. I have a currencymanger in play for use of displaying the current record of how many records. I think I need to do a search and find the row number of the select record and then use the CurrencyManager.postion to do this but have had no luck in 3 hours to locate anything I can use.

Combo Box Using Items Collection Bound To A Database Table / Dataset Is Not Recognizing Changes

Apr 14, 2009

Visual studio 2005 - vb.net..I have a user control on a form containing 15 combo boxes.All contain Y, N, and blank (for Yes, No, or blank) in the Items Collection property.Each of the combo boxes have a binding source to the same table, different fields.When you select a value Y, N, or blank for any of the fields and do a save, the values save while the application is open.Once you close and reopen, the values are gone.It appears the dataset does not recognize the change, so the values are not getting stored in the database table.  Is there something I can do or put in one of the events that would identify this as a change.

Dataset Not Updating When Bound Text Fields Are Changed In Code?

Sep 1, 2009

I am having issues understanding why it is that a text box that has been bound to a dataset correctly updates that dataset when the text in the box is manually changed i.e. by changing it using the keyboard but the dataset does not recognise the change when I change it in code.Am I missing something obvious? The text is changed in code when the user clicks on a command button that copies the text from another textbox on the form to this textbox.

[Code]...

As i mentioned, manually it works fine but when I use the comman button to change the text it does not recognise that any changes have occured.

How To Automatically Select Items In A Listbox

Nov 12, 2010

I have a listbox that displays SSRS report names and a separate listbox for displaying email addresses. Both report names and email addresses reside in separate SQL tables. This application allows my users to select an SSRS report, report parameters, export method and email a URL link to one or multiple recipients. This part works very well. One particular report has 6 recipients and I have been trying to come up with a way to automatically select these 6 email addresses whenever this one report is selected but I haven't had any luck being the neophyte .Net programmer that I am.

Multiple ListBox - User Cannot Select Same Items

I currently have two list boxes that have the exact same items in each. I don't want the user to be able to select the same item from both list boxes.

My code:
listbox1.Items.Add("SSS")
listbox1.Items.Add("AAA")
listbox2.Items.Add("SSS")
listbox2.Items.Add("AAA")

I'd like the user to not be able to select AAA & AAA from different list boxes, just SSS & AAA. I have way more items just thought I'd shorten it.

Listbox Items Colour - Two Types Of Items Populating In A Listbox (checked Listbox)

Apr 28, 2009

I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

Clearing Datagrid Or The Dataset Bound To It?

Feb 15, 2012

I am binding a dataset (dsTest) with a table called "TempResult" to a datagrid (DatagridView1).The purpose of the datagrid is to display test labels (set elsewhere in the software) and to allow the user to enter results into an empty column titled results.To achieve this I've filled the dataset with the required test labels then added a column called "Result" with a default value of 0.00.The user can enter numbers into the "Result" column on the grid then click a button "ADD" to update the changes to the datatset,When I first open the form the datagrid shows the correct information and any changes made to the Result column are updated correctly - all is well.

Private Sub Add_Results()
Dim ResultColumn As DataColumn
Dim Rows As Integer
Dim i As Integer

[code]....

If I close the form and open it up again (i.e. the user wants to add more results) the datagrid shows the results entered the last time the form was use and any changes made to the grid are not updated and the form won't work again until the software is reloaded.

Fill Bound DataSet In Backgroundworker?

Jul 10, 2010

I've added a Data Source to my project and a table from that Database (SQL 2005)

It is a rather large table and takes a LONG time to load the form. I was thinking of loading the auto-generated "Fill" statement in a Backgroundworker, but it doesn't seem to be doing anything. I have the Fill statement in the DoWork event, but it never "finishes" it seems. My BindingNavigator stays at 0.

I looked at jmc's sig link and everywhere I look, it seems like I'm going to have to iterate one at a time, but how can I do this for a bound datasource?

Keep The DGV Inside The Group Box When It Is Not Bound To A Dataset?

Aug 30, 2009

I have a DGV which I am laying out in code as it is unbound. The problem I have is when it is inside a group box, it moves outside the group box to the top of the form.

If the DGV is not enclosed in a group box it stays put. I have tried docking the DGV to the group box but that does not work. If I have a dataset bound to the DGV, then there are no problems.

How can I keep the DGV inside the group box when it is not bound to a dataset?

DataGridView Unchanged After Adding Row To Bound DataSet

Jun 11, 2010

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've bound this dataset to the DGV thru the designer. Here is the line of code that is erroring out:

Remove Row From DataSet If Bound Table Is Sorted?

I have a DataGridView that is bound to a DataSet and I allow someone to remove a row from the table and I remove the row from the set. My code looks like this:

ds.Tables(0).Rows(dgCourseList.SelectedRows(0).Index).Delete()

My problem I found is if the grid gets sorted the index of the rows no longer corresponds to the indexes in the DataSet. As a result the wrong rows get removed from the set.

Can I solve this problem with maybe having to sort the DataSet on some sort event of the DataGridView?

Validating And Storing Selections From A Dataset Bound Combobox

Oct 20, 2009

I have a combobox that is bound to a dataset. The dataset has 3 columns of data. at any given time there could NOT be any data in the dataset.

When someone selects an item from the box I want to store data from 2 of the columns of the row they selected.I do the 'store' in the selectedindexchanged event.

so currently I am assigning each column/row value to a property from a datarowview i get from combobox.selecteditem.

Code:dim column1 = drv.row.item(0).tostringdim column2 = drv.row.item(1).tostring

But I am getting NullReference exceptions all over the place when there is not data.So i have to wrap it all in a try catch and assign nothing to the properties when the Null exception fires.

I want to also validate that there is a selection made. There must be a selection made if there is no data in the DS fill it.I do this in the combobox validate event.

It just seems like there is a better way to check for no data coming from the combobox.

I wish there was a way to do some sort of .count on the datarowview you get back from the combobox.selecteditem but anything i have found also gives a null ref exception if used.

Also what is used to programmaticly change the selected item?

Beyond this, I have a simple textbox and button on a page.
