VS 2008 DataGridView - Refresh Without Changing Sort Order
Nov 15, 2009
Asset Database, with DataGridView that is populated with desktop and laptop PC's by 'Office' and 'PC Type' (Combos). You can double-click a row to open an editing screen to edit the PC details eg: assigned user, purchase date, serial number and so on. The problem
I am using VB.NET 2008 My DataGridView is bound to a DataSet. After adding a DataGridView row (from another form), I needed to sort the DataGridView in order to put the new row in the appropriate place. I needed to be able to identify the current sort column and the current sort direction (ascending/descending) but I was unable to find out how to obtain that information from the DataGridView properties. Consequently I had to do it the hard way via my own coding. The sort column name (or names) and the sort direction then became available to my program in the global variables.
I have been experimenting with datagridview by designing a bill tracking program. The first challenge I haven't been able to solve myself is how to sort it. I managed to figure out how to save and update from xml but I don't know how to put it in any particular order. Is this possible with it bound, or would I need to write particular code to custom-fill in the date grid? All I am looking for is an a-z sort.
I have a subroutine for changing the datagridview's columns' colors on form load.Now, everytime the user change a cell's value, the cell's backcolor is changed.If the user click 'save' the program will call the subroutine for changing color.I got everything working except the part that it will return to the color on load after save. I think I should refresh my datagridview but I don't know how to do this.
I want to sort from ascending order so i will know where will be the first priority but i dont know what is lacking in my code and whats wrong with it.
Here's my code for sorting i dont know if this is right. It say's IndexoutOfrangeException was unhandled i dont know what's the meaning of that. . . .
Dim p() As Integer = {TextBox1.Text, TextBox2.Text, TextBox3.Text, TextBox4.Text, TextBox5.Text} Dim a, c, d, f As Integer
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.
I have a datagridview in Visual Studio 2008. I am using the binding navigator to add rows to the grid. I have two text boxes on the form that I am using as the data entry method. I have dragged these onto the form as details items from the dataset and placed them below the datagrid.
I hit add item item on the navigator, fill out the test boxes and then hit the save button on the navigator and it sends the data to the database but is doesn't not update the datagrid. The only way that I can seem to correctly display the new row is to use the Datagrid fill method
My code is below.
Private Sub CustomersBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CustomersBindingNavigatorSaveItem.Click Me.Validate()
I want to send the data that i just entered into a cell to an If-statemens to perform certain functions.I an using the following code just for testing purposes:
1 Private Sub DGVReceipt_CellLeave(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DGVReceipt.CellLeave
I am loading an array with data at form load from a text file. I then display that data in a label box. When a user clicks a button I want to sort the data in ascending order. I have a sort code right nowbut it is not correct at all! Another problem i dont know if it will correctly sort becuase the data from the input file is like this: C2 CA D4 S9 HA C4 CQ D3 DA DQ .....AND SO ON AND SO on up to 52 like a card deck, here is my
This works great and sorts on L_Name. But I am trying to allow the user to sort the gridview themselves so I am passing in the SortExpression as a string. But I don't know how to incorperate the SortExpression into the LINQ Query. I tried Order By c. & SortExpression but that did not work.
I am trying to do a bubble sort using arrays and i am trying to sort a word in its alphabetical order... and my problem is that. i could not assign a value into my array from my textbox and get the length of the word from the text box... i do have this alogorithm'dim asd () as string'asd() = Text1.text'Len(asd()) but it seems that it doesn't work that way as what i am thinking.how to do it? it has been bothering me for days now and even if i do a lot of library sessions for this but still i could not find what i want to know.
I have 1 column of buttons that have names in them. i just want to be able to see the in alphabetical order A to Z down. at the moment they just list randomly down. they also have a unique id in the .tag field. How to achieve this alphabetical sort? i am using Visual Basic 2010 Express.
Here is the code that creates the buttons under one another.
HTML
Buttons(i) = New Button 'Create a new button object in the array element With Buttons(i) .AutoEllipsis = True
Let say the columns that i highlighted is X and Y. I have to arrange the small Y first which is -10000 then arrage big Y which -11000 then arrange again samall Y followed by big Y. Here i only have -10000 and -11000. but let say i also have -12000 so i have to arrange -10000 first then -11000 then -12000. But i also have to look at X column. If let say x value is same next line so it should side by side like i higlighted the two row.
the lines should be identified by [B3] as it will be one group. Can we use IComparer methode here? How to arrange the lines in order thet i want?
I have a datagridview showing data from an Access database. I have dragged the datagridview from "Data Sources" window - and not written any code. In bindingsource I have choose to sort on an autonumber field. Is it possible to let the user use the mouse to change the order, and the database to remember this the next time the user starts the application.I guess I have to have a number field in the database, and write code to change the value in number field as the user change order - and then save this back to the database? Does the datagridview support changing order by mouse at all?
I'm successfully refreshing my DataGridView/Access DB by using the following.[cod]My only problem is after the refreshes the DGV rolls back to the first entry.Is there anyway to have it refresh but stay on the same line?
I have a generic list, like this: System.Collections.Generic.List<Question> myquestions = new System.Collections.Generic.List<Question>();
And I have a paging example, using a LINQ table acquried from database, doing this for paging: var questions = context.Questions .OrderBy(sidx + " " + sord) .Skip(pageIndex * pageSize) .Take(pageSize);
Right now, for paging my populated from code list, I have: var questionss = myquestions .OrderBy(x => x.Id) .Skip(pageIndex * pageSize) .Take(pageSize);
And what I want is being able to order "myquestions" by a string as in the above example. Is that possible?
I am trying to do two different things in one giant query. I am trying to specify a custom sort order which i have working in the following query:
Code: SELECT Count(*), Status, 1 as OrderCol FROM tblSurvey WHERE Status = 'Complete - CD Sent to Customer' AND SurveyTable = 'tblSurveySoVA' GROUP BY Status
I have a Datagridview whose source is a BindingSource. The grid has columns Source,FormatShort, and Number among others. I would like to sort the grid's appearance according to the order below:
Drag treeview named TreeView1, textbox named TextBox1,button named Button1.I m adding nodes programmatically. Select the node,Enter text in TextBox1 & then click on Button1 to add the node.Mine code is doing this, I want that when the user add nodes it automatically sorts.
Suppose user selects All(node) that is added on form_load,enter 1 in textbox1, click on buuton1,node added.Second time again user selects All,enter 3 in textbox1,click on button1, node added.Now the user enters 2 in textbox,click on button,node added. I want that nodes are automatically sorted after adding.I want
