Winforms - Finding Text From The Datagrid View?
Nov 2, 2011
I have a data grid view in one windows form named "GridViewForm". When the user search for the text from the search box from another window form named "FindForm", I want to highlight all the matching result in the data grid view. The search type can be exact or partial.For eg.If the user search for the text "stack", then the words "stack" from [Stack, stack-over, stacks, stack exchange] should be highlighted and first cell that match the query should be selected. When the user press next button then another cell that match the search query should be selected.My code for finding the text is like follow for it search only the exact word.
Dim gridRow As Integer = 0
Dim gridColumn As Integer = 0
For Each Row As DataGridViewRow In AccountsDataGridView.Rows
[code]....

what I am trying to do is, when a ListView loads, for the code to check the entry in column one, and then return a message box if the column contains a specific date.
I am using:
SUB I DONT KNOW THE METHOD TO INSERT THIS INTO. I NEED IT CHECKED WHEN THE LISTVIEW CHANGES
If lvuPreviousJobs.SelectedItems(0).SubItems(2).Text = "31/12/9999" Then
{
MsgBox("TEST")

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I'm populating a datagrid using Linq--standard kind of stuff (code below). For some reason however my ultraDataGrid is stuck in some kind of read-only mode. I've checked all the grid properties I can think of. Is that a result of binding to a Linq data source? Any example code of an updatable grid that uses Linq?
db = New DataContext
myData = New dataClass
dataUltraGrid.DataSource = From table _
In db.profiles _
Select table.field1, table.field2...

Is there a shortcut to get to the designview form in a winforms project in visual studio 2010.F7 will take you to code behind class form and shift + F7 will take you to design mode. Is there a shortcut to filename.designer.cs formWhere you have the control definitions, delegates (for click event etc). defined. I go to the form often if I change the name of click event etc.I have to go through solution explorer and click on the file. Is there a shortcut like F7 that opens the designer.cs file?

The ContextMenuStrip tied to the ListView control. However, the right click option (edit)appear where ever i click on the ListView area, this gives me exceptional error because the implementation of edit can only cope with a selected row. I only want it to appear when on a selected row (blue highlighted row). How can i do it?

I have a tbl called tblProjectpatients which also has 2 fields Yes and No (these have the data type - Bit).
These two fields have been populated with false and true values.
On my form, I have a datagridview which is populated with various values from tblProjectpatients.
The problem am facing is that the checkbox's for Yes and No on the datagridview are empty at runtime eventhough at the backend they have either False or True values.
I am expecting the checkbox showing on the datagridview to be either checked or Not Checked depending on the True or false values.

i'm having with a problem to refresh my datagrid view. I have 2forms and a database create from msaccess2010. This programme is too simple, in form1 requesting a costumer name and save button. After being saved, it'll show form2 which is database in datagrid view. Yes, in first save the name of costumer are being shown there but after i close (which is 'hide' actually,i cant use 'close' due to particular reason) and reinsert the data in form 1 and save it,the second data are not being shown in form2. So my question is,how can i make the data refresh(by form load or button refresh,any of them)?
