I would like to know how I can make this happen?
When I double click on a row on a datagrid, a form will appear like the above screenshot.
When I double click on the row which consist of Brian/Kendall, a form will appear and should show Brian in the First Name text box and Kendall should appear in the Last Name textbox.
I use a simple master-detail form using Visual basic 2005 express edition and ms sql server 2005 express edition, as well.
The master table is dept (deptno int, dname nvarchar(50)) .
The deail table is emp (empno int, deptno int, ename nvarchar(50)).
The primary key for the dept table is deptno and for the emp table is empno.
There is also a foreign key (deptno on emp table).
I created a new project, connected to a db (called test.mdf) and created a data source consisting the two of the above reffered tables.
I dragged and dropped these tables on the form and i noticed the following:
1)When the form opens... the system queries the database and displays the data on each block on the form.
2)I insert and/or update a record on the master table (dept) and everything goes well...
3)I try to insert and/or update a record on the detail table (emp) and nothing is changed on the detail table - without any error.
4)When i try to insert and/or update a record on the detail table (emp) which violates the primary key constraint or foreign key the system complaints...(as expected).
My Datagridview displays data perfectly. What I want is that if I click or doubleclick cell of
datagrid it will shows myedit form...
code to displays data'[code...]
I didn't get the result I want from the following code:
Private Sub tblView_SelectionChanged(ByVal sender As System.oject, ByVal e as System.EventArgs)Handles tblView.SelectionChanged
Dim st As String = tblView.SelectedRows.ToString
[Code]....
I wanted the data I selected on the datagridview row to be display in the textbox, but it displays the error message that st(0) produces "S" which is incompatible to my RackID data type.
I have a situation where I am handling both single & double mouse click events on a form. In both cases something has to be loaded, however when a double click occurs, I do not wish to execute the code attached to the single click event.Is there a way to intercept the mouse click's and check if double or single and then execute the right event appropriately?
View 2 RepliesI have a detail view control in my aspx form. I have the following field in my detail view:
NameId
Name
ContactNo
But I dont want to allow the user to edit the "NameId" field. So I set it as read only and Insert Visible. But setting it dosen't allow me to update. If all the fields are set to be allow for editing, the update work successfully. How should I go about doing it?

I am creating an application for a college assignment called "Quote Manager" - the idea is a writer can save his / her favourite quotes, then go back to them and be able to print them.So I had this idea where all the quotes are loaded into a datagrid view on the main screen of the program and the user can double click on the quote he / she wants to load.
I don't want any code given I would also post what I have got so far but at the moment I am at work.What I want is to know how to manipultate the datagridview control so when a cell is double clicked a saved html page will load from a database.
I have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
If a have a lable called: lblWarning. I'd like to display it (Visible = True) when the detail band does not have any records. The label is in the group footer.

I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code:
Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1
AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID
Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.
i have a master detail form with databound datagridviews.my detail datagridview is bound to FKFieldSubFieldLookupTableBindingSource and it shows the linked sub-fields when the main field changes. This datagrid has only one column which is the sub-field names column. this column type is ComboBox.here are this combobox details
DataSource = subFieldLookupBindingSource
DisplayMember = sub_field_name
value Member = sub_field_id
No Problem until here.When i click on the Cell combobox I get the list of all the sub-fields. I don't want this. because once a sub-field has been associated with a Master field, it should not be available for other Master fields.What i did was, In the SubFieldLookup Dataset, i added a query to get all those sub-fields which haven't been associated yet.but this clears up the detail datagrid and shows blank comboboxes where it is supposed to have the sub-fields.
I simplly want the master-detail mechanism to work and when i want to add a new sub-field, and click the combobox in sub-fields datagrid, i want to have only those sub-fields which are marked False in database in the column 'alreadyAssociated'.

I need to be able to double-click a row or column in a row to use a field (in this case the Student ID field, the 4th column if counting form 0) to get that row from a database onto a separate form and be able to edit and save it. I have no idea how to make this happen since it is not covered in the class beyond basically displaying database data in DataGridView, I chose to use this functionality in my final project (to be fancy I guess) with the thought that it will be easy to accomplish but am finding it is not quite as easy as I thought. My current code is below;

I have a windows form that can search for data and the results are results are returned in a Datagridview. The Datagridview is bound to a custom datatable object. On the CellDoubleClick and CellContentDoubleClick events, a new form is supposed to open which will display the results of that row. What I am noticing is that the datagridview doesn't always fire when I immediately double-click on a particular row. It would appear that I have to first click on the row to "select" it, then double-click the row so the event will fire. Is there a way to remove this intermediate "select" step? Is there a property in the Datagridview that needs to be activated so the double-click events will fire right away? Does something possibly need to be done in another DatagridView event?

View 8 RepliesI have a form that is set up like a master/detail form - fields on top with a child grid below. The difference here is that the child grid is reflective of a recursive relationship. That is the ID of the master has a one-to-many relationship with another attribute called "parent." the child grid displays all the children for that parent. It works properly except when a new record is being added to the master.My issue is that when the user clicks on the Add New button, the child grid then displays all the available parent records in the system instead of an empty grid. Once the new master (parent) record is saved, the grid reverts to proper behavior.Thus, my question: How do I prevent the child grid from displaying all the parent records when a new master (parent) record is being added?
View 1 RepliesI would love some help on how to get a DataGridView's Row & Column location on a mouse double click. My program requires that I dynamically add n-number of tabpages with DGV's so I declare my own class that inherits TabPages and creates its own DGV control.

I need advice on how to pass the details of a double clicked datagrid record to another form and display as text boxes etc. This will act as an edit form for the user once they have clicked their desired record.

Working in the interface I find it very frustrating that when you double click something in a form, it automatically enters code that you have to delete, then exit out when you were only trying to single click. Is there any way to disable this double click feature? Or possibly change it so if you press CTRL and click it automatically brings up the Code
View 2 RepliesI've created a datagrid and made it read only, I want to double click it and it will open a new form with all the data so I can edit it and press save.
I have a form called New client where you add the name address etc and press save.
I want the fields already on the add client form to fill in the data from the row you double click on the grid.
I am trying to prevent a form from being moved or resized by the user. I am able to do that IF the user double clicks the form (I basically resize the form to full screen, andreposition it to 0,0). This is loads of flickering, but it works. However this seems to only work if the user double clicks the form. After loading, if you grab to top bar, you can move it.
