IDE :: DataGridView Control Properties Have Disappeared?
Sep 21, 2009
Greetings. I have a DataGridView control in a form, and as of a day ago, when I click on the control, I get *no* properties listed in the Properties pane of the IDE. The properties pane is totally blank. Neither properties nor events are visible. I have tried everything. Prior to this, the properties and events displayed normally.
Other controls' properties are displayed when I click on them, but not the DataGridView control. If, after clicking on my DataGridView control, I use the combo-box on the Properties pane to look at any other control's properties, they come right up. If I then select my control's name (DataGridView1) in the Properties pane combo-box, the IDE crashes completely and I have to restart.
I tried a repair re-installation. The same things happens.
I can set properties etc. programatically, but that sorta defeats the point of an IDE, not so?

I've built a custom user control in VS2010, incorporating two datagridviews, and asplitpanel - The idea is that there is a "Main" datagridview control, and the second is an internally controlled grid that (when shown) displays the Columns which are set as invisible. This allows the user to drag the columns onto the main grid, in order to display the columns.This all works fairly well. I've set the modifiers property on the Main DataGridView to public, so that by and large, the developers can make use of the control just like a normal DGV (albeit with an extra level to the code).
I've also created dummy events for each of the events that the DGV normally raises, and pass them through the usercontrol, so that the developers can attach to the DGV events as normal. Again, this appears to work fine.Unfortunately, I've run into a problem. I'm trying to set the RowSizeMode to DisplayedCells (or indeed any value). If I try it in the designer, it appears to retain the change until I run the application, after which the property reverts back to normal.

I have combed these forums and the 'net and can't find an answer to my specific problem. My menu strip disappeared (after deleting a small secondary form within my project). I therefore created a new strip and while recreating the menu items realized that the original menu items are still present, showing in my properties list. I have checked my design file as well and the original menu strip is definitely gone but the original menu items are there. I don't have many items so I would have no problem just deleting the original ones but I can't see them to delete them! I have checked and they are all set to visible. I have also moved everything on my form to see if it is behind anything else.

For some reason a control on my form has disappeared. I can select it in the properties window and view all the properties (Visible = True) but I can't see it. It also doesn't appear when I run the form. How can I delete it, or bring it back?

Yesterday I added a new user control to a project I was working on: right click on the project name "Estimator", then add, then new item, then on the add new item dialog I typed the name of the user control, and I created my ButtonWithCheck.vb control.
My user control appeared on the toolbox, I inserted it in a form, used it, kept working on my project, and everything was fine. I saved and closed the solution.
Today I open the solution and I got an error: "Could not find type 'Estimator.ButtonWithCheck'. Please make sure..."
Why a project saved while working doesn't load?

The charting control has disappeared from my toolbox in VS2010. I know it was there when I upgraded to 2010 a few weeks ago. Both chart items are checked in the Choose Toolbox Items dialog but it doesn't show up in the toolbox. I'm pretty sure it was under the Data category. I tried resetting the toolbox but that didnt bring it back.

I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)

I have my own class of graphic objects, and now I'd like to allow a user to right-click on one of those within the application and see a properties window. Is there a pre-built dialog or control for displaying properties at runtime? I'd like to have something just like the IDE properties window button for my application.

What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.

I would like to be able to set Control visual properties such as color, boarder, flat style, etc. on the base class of the control so that as I add new instances of the control, each instance inherits the visual properties of the base. I have tried using Application Settings but it appears as though I need to reference an application setting manually each time I add the control to a form. This is a Windows Form question.

I tried it and get an error but maybe I'm tring the wrong way. Can a usercontrol inherate an application defined class ie.. could you inheritance a classic rect class into a user control to add the hight and width properties to the control without having to do all the coding all over again? Currently I just declair a private instance of the class within the control and then encapsalate. It would be nice if I could just inherit all the functionality of my classes into controls designed to implament the classes.

When in designer, if I add a DataGridView to a windows form, the properties do not show in the properties window. I'm using Visual Studio on XP. The problem exisits even if I create a new project, open a windows form and then drag a DataGridView onto the form.The grid view is present because I can add columns, etc. The only issue is the properties don't display. So I can't rename it from DataGridView1 unless I do it in code.

I'm making a data entry form using a datagridview and I want to control which cells in a row are visible. For example, I only want the first cell in a new row to be visible until I validate what was entered - then I'll either fill in the other cells with data or ask for user input.

Is there anyway that I can access all the properties of a control during runtime and
get their values. I dont want to specify the property name. I should get the all the
property names and their values. It is something like reflection namespace in VB.NEt

i had designed a form with various controls added some days ago. Accordingly i had coded the controls. And today i didnt like the look and feel of the form, so i copied the controls for a while and then re-pasted it over a new control (panel). Now when i double click to see the underlying code of the control generates a new event. I mean i had a button as Button1 and its underlying code was under the Button1_Click event. But now its is like Button1_Click_1 which i dont understand. Is it due to formation of control array or what? I want the button to be remapped to Button1_Click event.

I went to go open up my form a minute ago and everything is missing!!! It is all there, but it is not. The form looks like a completely blank form with nothing on it. But all the controls are still there, somewhere, because if I click the dropdown at the top of the properties window, I still see all my controls, and my code does not have errors. It was working fine 10 minutes ago!!

I need a few columns in my datagridview to have the font be aligned to the right, but no matter what code I use it doesnt work.
I would also like my columns with numbers to always have 2 decimals.
And lastly I would like the right side of the column header to be blank and not movable. I can do this by adding another column to my table with a blank name and then set the width to fill, but the problem is I can just move this around, which is not good, I want to freeze it so it looks good. I do want to be able to move around on the other columns, just not this one. Unless there is another way to do that?

I am able to bind my datasource to the textblock for the display text. However I would like to set the Fontweight to bold if the value of the checkbox foo is checked. I'm trying to use IMultiValueConverter to accomplish this, but have had no luck so far.
<CheckBox Name="foo"/>
<TextBlock Name="bar" Text="{Binding Path=Name}">
<TextBlock.FontWeight>

In our IDE, for example, Visual Studio, if we display the properties of a System.Windows.Forms.Button control, we see some properties that expose anoter set of properties. For example: FlatAppearance, Font, Location, Margin, etcetera.I would like to do something similar in a custom control.I know the code behind is wrong, but here is an example of what I´m trying to do:
Public Class StateOfMyCustomControl
Public Enum EnumVisibility
Visible
[code]....
In my IDE, in the properties window of my custom control, I would like to see my property State, with the possibility of display it to set the properties Visibility and EventManagement.

I have a blank winform. A textbox control with name textbox1 being added to the winform. During the form load event, I retrieve 2 string values from database and store these values into TextboxName and TextboxValue variables of string type.
I use TextboxName variable to store that textbox control name (i.e. currently TextboxName = "textbox1") and TextboxValue variable to store that textbox's text (i.e. currently TextboxValue = "Hello world"). My question is how to set the textbox1.text property without have to resort to following code:
If TextboxName = "textbox1" Then
textbox1.Text = TextboxValue
End If
how to set the textbox1.Text property without have to use IF...Then construct?

I have several controls on a page that contain the word "DATE" in the ID. These are specific text boxes for dates only.
Here is an example of what I need to do for each text box control with "DATE" in the ID:
Birth_Date.Text = fnLib.formatDate(Birth_Date.Text, 1)
Anniversary_Date.Text = fnLib.formatDate(Anniversary_Date.Text, 1)
Rather than do this for every single control, is there a way I could do this in some kind of For Each Loop?

adding the properties of a control to its parent? Without having to rewrite all the properties... For example, if I have an user control with a button inside, and I want to have the "text align" property of the button, in the list of properties of the usercontrol. If not, is there a way of making the child control of an usercontrol editable?

I'm wanting to dynamically create some controls relative to controls already placed on the forum at design stage, how do I find the locations of the controls that are already placed?For example, I have a label called lblDateTime, its location is (13, 167) and its size is (65, 13).In my code, I want to place a new label below this label.I've tried to set the location and size properties of the new label using the location and size properties of lblDateTime.Size works, no problem, but the location of lblDateTime always returns as 0,0.[code]I want to set lblMessage DateTime. Location to (13, 180), but I'm actually setting it to (0, 13)What confuses me most is that Me.lblDateTime.Size is returning the correct values, so it's not like my code isn't finding the control.
