Dynamically Swap A String For An Image In Datagridview?
Dec 24, 2011
In my windows form I have an empty datagridview that contains strings loaded from a csvfile. The datagridview has no initial column collection. There are four columns in the csv file. In the csv file, columns 1 and 2 have values of true orfalse. So far I am able to load the text perfectly.
What I want to do is change the strings "true" or "false" into an image in my resources (a pretty green checkmark and a red x).
I would like to leave the csv file text as it is, and then change the columns dynamically.
Then, when I save the information back to the csv file, the images must be converted to text strings to accomodate the csv.

i am hoping that the possibility to locate all the controls that contain a certain image from the resources, and swap out that image for every control that contained it, will help me narrow down on the simple coding.
something similar to:
for every control that contains backgroundimage=my.resources.imagefound
replace backgroundimage=my.resources.imagereplaced
i tried the above code and it did not work.. lol..

i want to write a code to swap the words in a string.
Input - I like cake
Output - cake I like
To do this it would be great if there is a way to determine the index of each word.Like
1- I
2- like
3- cake
Then I can swap the words.But I have no idea how to do it.Currently I have written the code to count the number of words in a string and to get the average.
Dim str As String = Me.t1.Text
Dim strA() As String = str.Split(" ")
Dim TChrs As Int32

I have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.

I use this code to get an image and add it to a image list
Visual Basic
Private Sub LoadWebImageToPictureBoxd(ByVal ImageURL As String)
Dim objImage As MemoryStream
Dim objwebClient As WebClient
Dim sURL As String = Trim(ImageURL)
Dim bAns As Boolean
[Code] .....
The code at the bottom should set the image depending on what the items index is but it doesn't work.

I'm dynamically creating a button control, and I'd like to add a background image from my resources thing to the button.
Now, I'm pretty sure it would be:
CODE:
But I don't know how to refer to an image that is in my project resources.
I've tried:
CODE:
But that gives error:Value of type 'System.Drawing.Bitmap' cannot be converted to 'String'.

I have a DataGridViewImageColumn that should display an image for only certain rows. After I bind a generic list of classes to my datagrid, I loop through each row and update the image cell with an image that is an embedded resource for the rows that require the image. This works great if the form has been fully loaded. However, when I attempt this on form load the image doesn't show up? I also can't perform simpler things such as changing the row background color on form load. Should I be performing this logic in a different event after form load?
For i As Integer = 0 To dgvRoles.Rows.Count - 1
Dim imageStream As System.IO.Stream = Nothing
imageStream = Me.GetType().Assembly.GetManifestResourceStream("MyApplication.Timer.png")

i am developing application with Datagridview using vb.net. the application has to add a DGVw control into a tabpage. i am working on a provision to the user to add and delete a row by clicking the datagridview button column. i am encountering a problem while inserting rows in between two rows. the same piece of code is working fine when we manually drag and drop a dgvw wherea it is not working when we do it dynamically. it is throwing error saying that"dynamic insertion is not possible'.
approach 1:drag a tab control, incl a tap page, drag a datagridview, add a datagridview button column, and finally a command button.declared in the top of the class declaration.

I have an app that has a DataGridView with a few buttons. My intent is to have the DataGridView populate with the data associated with the button clicked. So if you click the States button it'll fill the DataGridView with the DataSet I have created with a link to a SQL table with a list of States.

I have a datagrid where the first column is for image button for expand purpose. The visibility of the image depends on some conditions row by row. I am trying to handle this in ItemDataBound event, and using e.item.cell(0).findcontrol("imageButton").visible = false. The first cell of this row therefore disappears even that the size is specified in the ItemStyle tag.

I have tree buttons (or maybe textbox's) when i click on button: A and then on button B , i would like to swap the values of A and B. Then if i click on C and on A i would like to swap the values again. This is for either a button or textbox. I think the code should be similar.

i have a pretty standard crystal report that shows a quote for materials for various customers - i also have a form, lets call it form1 for arguments sake - on form 1 i have two data grid views - one attaches to the customer table, one attaches to the quote table. Customer and quotes are linked on customer number at the database level.
i dragged and dropped these on to the form and they work great, as i scroll through each customer in the customer datagridview, that customer's respective quotes show up in the quotes datagridview.
now the problem - as a third tier, i have a crystalreportviewer that has all the nice graphics and presentation of this quote, company logo, etc etc, i've also done all the standard report sources etc etc, but the darn thing won't cycle through the quotes as i scroll through them in the quotes datagridview.
am i missing something simple? all i want to do is highlight "abc company", see their list of 50 different quotes pop up in the quotes datagrid view, then click a quote number and see the quote display in the fancy smanshy crystal report viewer so i can then print or export or whatever.
