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.
how to Load Image in Crystal report Dynamically?Im creating students id in crystal report.the image is accessible through path "C:mysoftwarepicturesstudent001.jpg"
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.
in order to create my own type of columns. USERNAME to have type ComboBox NAME to be type normal like it comes from dataset But I don't know how to create a a column that is combobox and another one that is normal like it comes from dataset.
VB.NET 4.0 framework Windows Forms Application. So I have a DataGridView that I have dropped on my form in designer, set all the columns to readOnly, AllowUserToAddRows = FalseAllowUserToDeleteRows = False. Now for the part where it the code is going bad at.
My function Looks Like this: Private Sub fill_items() Dim prop As List(Of property_info) = db.property_info.ToList
like this i have n number of questions in my word document. so my need is i need to read the questions and fill it up in the datagridview with yes or know chek box. my datagridview appearance would be as follows. so the peson who is viewing the questions and can make yes or know option using the check box.if the person chooses no option he has to enter the reason the reason column. so i have to do this dynamically. means that binding datagridview with checkbox ,textbox, data dynamically. how to do this please because after the datas entered in the datagridview i have to loop through rows and i have populate into another word document. so please if there is any sample
i reading values from MSword an populated the vlaues in Datatable. there is no problem in this. then my datagridview must contain checkbox at the position of second column.so i have created the column programatically. then i have looped the datatable and added the rows in datagridview. [note: i am ot using Datasource Property because i need checkbox column at position.so i create the columns dynamically and add the values].
I try to add text strings to an image but keep the metadata of the original image. The problem is How can I save ImgMetaData (from the original image) to the new image?
Here are the codes:
Public ImgMetaData As BitmapMetadata Public myImageCodecInfo As ImageCodecInfo Public myEncoder As Encoder
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.
