I add items to my DataGridView:
DataGridView.Rows.Add("Item")
And finally I number the HeaderCell using this code:
For Each Row As System.Windows.Forms.DataGridViewRow In MainDataGridViewX.Rows
Is there a way to number it while adding items to the DataGridView so do it at the same time?

when i click an item in my datagridview, how can i get the item value?i thought datagridview.item would give me that.
View 5 RepliesI have an Access database with a Parts table. I'm using tableadapters in my project. A datagridview on my form is filled manually in code. One column of the DGV contains a columntype of combobox. I've got a bindingsource on my form whose source is the Parts tableadapter. The combobox column is tied to the bindingsource and is displaying fldDescription.
The part descriptions can be changed by the users, but the original part description is saved in another table that is used to fill the grid. If part "widget" gets changed to "widget, large" I can no longer display "widget" in the combobox of the grid. I need to know how to be able to add it to the bindingsource so I can display it in the combobox. I don't want it saved to the Parts table though.
I'm using a comboboxcell in a datagridview with the combobox autocompletemode set to SuggestAppend.When I enter the cell and start typing, the autocomplete window pops up. When I click an item in the autocomplete list, the cell value is set and the cell exits edit mode. This has the same effect as selecting an item with up/down arrow keys from the autocomplete list and pressing the enter key.)
I want to copy that behaviour when an item is selected from the combobox dropdown list.E.g. if the user clicks the dropdown arrow button to open the dropdown list, then clicks an item in the list, the cell value should be set to that item, the dropdown should close, and the cell should exit edit mode.I've tried adding a handler to the combobox mouse click event, but the combobox only seems to receive that event if the main part of the combobox is clicked, but not if the mouse is clicked somewhere in the dropdown part. I don't think this matters if the combobox is used in a datagridview or by itself. how to capture a mouse click in the dropdown part of the combobox?
DataGridViewX.CurrentRow.Cells.Item(0).Value.ToString
If the item is blank and no data is entered it will throw a null exception, so the question is that how can I check if the item is null or not? Even using this:
If DataGridViewX.CurrentRow.Cells.Item(0).Value.ToString IsNot Nothing Then ...
Will throw the exception!

View 2 RepliesI have created datagridview from my datasource using drag and drap. Without any changes it works fine, I can add, edit, delete and save. I added additional queries with my dataset which is fillby. My problem now is if I change fill with fillby the updateall is dosn't work anymore.

I have a List of an object, set to DataSource of a BindingSource, set to DataSource of a DataGridView. Then I added a DataGridViewButtonColumn which I want a click to remove that record from the collection. So I simply call collection. RemoveAt (e.rowIndex) from the DataGridView CellClick event. However this produces an IndexOutOfRange Exception; "1 does not have a value"..
So is happening here? I have maybe a vague idea, but would like to understand exactly which events are failing etc.. and what do i need to do to perform this action properly?
EDIT: This seems not to happen if I use a BindingList.. But when using a List, I get this problem..

View 1 RepliesSo am back again with dattagridview and comboboxes...sorry for the troubless.. Now let me come to my scenario aka problem..I have 2 dataviewgrids in my WINDOWS APPLICATION FORM (VB.net).The first grid populates some data from the SQLSERVER 2005 DB.When I click on any cell of the first grid, my second grid shows up and populates with the data corresponding to the cell which I have clicked in the grid 1.This is working perfect and so far so good.In the second grid I have 3 combobox columns and some textbox columns..The three combobox columns in this grid are also populated from the DB only usng datasets and datasource.In the first Combobox Column if I select one value, then the corresponding values are filled into the other textboxcolumns.This is also working good.The other 2 comboboxcolumns are also populated from database using different datasets..
Am about to add a master data ( i.e data into the first grid).it got added and after that a msgbox pops up sayn u must add data into the second grid as well.so the user is adding the data in the second grid.(all works except the new requirement).he added something into the first row by selecting the comboboxcolumns and also editing the other columns in the first row.(he havent saved this row.This will happen when he clicks the save button in the form not in the grid)he goes into the second row .Now here he should not see the item from the combobox1 which he has selected in row1.
I have a menu item that appears when right clicking over a datagridview. From their the user hovers over a menuitem and a list of other menu items appears, once again this repeats. Giving soemthing like this.
---------
| FOO |---------
---------| BAR |------------
---------| FOOBAR |
-----------
There is only to be an event (addressof) handled on the the 3rd tier. With that being said I need to grab the parent.name from FOOBAR and the parent.name of the said parent (grandparent).Here is where I am at:
If currentMouseRow >= 0 AndAlso currentMouseColumn <= 1 Then
dataGridView_monitorMapping.Rows(currentMouseRow).Selected = True
mainMenu.MenuItems.Add(New MenuItem("Set Monitor(s) Settings"))

And the event handler

'TODO | Handle selection from right click menu.

View 1 RepliesI am searching a XML file for <Asset_Number> and then adding all children to DataGridView1, i can search but i dont know how to add item to the DataGridView Also my datagridview columns are created from a txt file

I have 1 table which has columns which include "parent" which says who the parent is if there is a parent, and "name" which has the name of the item. so for example
[Code]...
or something to that affect. the reason being that the user can do the autocomplete by typing a letter or a few letters, it will go to the parent and then they can use the enter key to move down 6 or so down at a time( if possible) or arrow to move 1 at a time down.
Is this possible in DGV or should I go use something else? I have seen this used in a program before but I do not know how it was implemented.
Data in Table1 is as follows
Code-------product--------weight
1-------------Apple----------2.00
2-------------Mango---------3.25
3-------------Banana---------6.50
Then I have Datagridview with three columns same as
Code, Product, Weight
I have following codes
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
str = "SELECT desc1,weight FROM master where code =" & Val(DataGridView1.Rows(0).Cells(0).Value)
dt = GetTable(str)
If dt.Rows.Count > 0 Then
DataGridView1.Rows(0).Cells(1).Value = Trim(dt.Rows(0).Item(0))
DataGridView1.Rows(0).Cells(2).Value = Trim(dt.Rows(0).Item(1))
End If
End Sub
When I enter 1 in row(0).cells(0) then other two columns fill automatically, but when enter 2 in next row then nothing retreived from database.I think this line should me modified as current row and current column.
str = "SELECT desc1,weight FROM master where code =" & Val(DataGridView1.Rows(0).Cells(0).Value)
I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

View 1 RepliesIs it possible to compare 2 dataitems and then display the result depending on the 2 values using if eval at run time?I have a ListView with databound controls. 1 is RedemptionChoice and the 2 is CashBack.When 1 reads "0" and 2 reads > 0.00 the output should read AUTO I have read many comments online and most point to create a new function within code behind but have found it impossible to implement on my own.I tried this as a test on the actual page:
<%# If(Eval("CashBackRedemptionChoice").Equals("0") & Eval("[CashBack]").Equals("0.00"), "Auto Cashback"))%>
2 needs to be greater than 0.00 for AUTO to be displayed. Hence I know this would not work. Just trying to give an example of what I would like.
