• Suren Reddy A DetailsView Control for Winforms?

  Hello, I have gotten spoiled by the new DetailsView control for ASP.Net 2.0 which encapsulates all of the dirty work needed to switch between viewing, inserting, updating, and deleting for a databound object. Now that I am working on a Winforms application I'm trying to figure out the best practice for handling these rather common tasks. I dislike the look and feel of "in place" editing on the grid view control. Do you typically create seperate forms for inserting/updating/viewing Do you group these items into different panels or group boxes and then play the "hide the unused control" game Do you simply use the same form for these actions and simply disable the textbox (or other editing controls) for view m ...Show All

• bslim Colour Control Lag Problems

  I have a user control, which is mad up of 216 checkbox (button appearance) to represent each web safe colour. Each has a event to relay the fact it has been clicked so can change the colour of whatever. The problem is when the control is displayed there is a big lag / slow down effect in the application. I wouldnt have thought 216 buttons/ checkboxes is that many to display on a screen each with a listener. But it appears so. Any ideas on what this could be Am i cgoing to have to come up with another way The only other way i can think of would be to draw 216 rectangles separately and go down that route. Only problem is i cant see how i would be able to show a selected colour by depressing it. Is the route to take Thanks ...Show All

• directSH Small accounting application Big headache (SAAB-H)

  Hello, This is part of a small database EntryForm. 9 TextBoxes: 1,2,3,Sum1 (all decimal(6,1), -- V1, V2, V3, EA, VTotal (all smallmoney) , --- EA (smallmoney). Three calculations: Sum1=1+2+3, V1=EA*1, Vtotal=V1+V2+V3. The order of the TextBoxes is 1-EA-Value1, 2-Value2, 3-Value3, Sum1-ValueTotal. The Sum1 and ValueTotal should be always updated regardless in which field the user choose to start entering data. The reason for the If, Else or If ElseIf statements is to always have some values in the TextBoxes. Note: All the TextBoxes.Text was stripped away to see better (1 is 1TextBox.Text, etc) Questions: How to initialize the Form without Fill (it always brings up the first record -eve ...Show All

• ryan.rogers I've a problem in reading the exact value of a checkboxcell in datagridview.

  I'm using C# - 2005 After checking or unchecking any particular checkboxcell, I'm not getting the exact boolean value, instead, I'm getting the older value. What I observed is, I've to click on some other cell and then, I can read the exact boolean value of that cell. Plz. help me with this issue. Best Regards Trinadh P. This is normal/natural since when you are editing that cell, its in edit mode and won't "commit" changes until you move away from that cell. You would have to either use EndEdit or click on some other cell To use End Edit: this.theDataGridView.EndEdit(); this will end the editing mode of that cell and commit changes to that editing cell Thank you Ahmed :) Sim ...Show All

• vish2007 sorting a sortedlist

  Hi All, I have a problem in my windows application with C#.net. I have around 50 Id and Name pairs and need to sort them after putting into a SortedList. In my data, ID is not unique. SortedList< object key, object value> So I can't put ID in place of Key( Key must be unique in sortedlist). I have created a class with Id and Name variables, passing the object in place of value, and some integer index in place of key. Now the Question is, how to sort the SortedList on ID. Please me help out, Thanks. One of the constructors of the SortedList take a IComparer as an argument. You can use this to sort the list. Keep in mind if the icomparer returns a 0 you will get an error about adding a ...Show All

• Mahesh Gaware Getting the MSI Package Path from a custom action

• VenkatB Overriding behaviour of control box buttons

  Hi there, I have a dialog that I basically want to stay "open" all the time - though its visibility can be toggled through an option in the "Windows" menu of my main form. The problem I'm having is that clicking the X in the control box at the top right of the dialog causes it to be closed and disposed. Is there any way to override this behaviour I've tried overriding the OnClosing, OnClosed, OnFormClosing and OnFormClosed methods, but to no avail. I don't really want to hide the control box. Never mind, found the solution myself. Needed to set e.Cancel to true in the override for OnFormClosing :) ...Show All

• Ravidhari String to Formula?

  I have a formula saved as a string, e.g "180/2+15" How can I process this formula to find the result (105) I would use the Microsoft Script Control to perform the calculations. Here is an example . The following is based on the assumption that your formula is always the same. I'm not aware of anyway to convert a string representation of an operator to an actual operator. You need to manipulate the string with the string object's SubString and IndexOf methods and save each number in a separate string object. Once you do that.. you'd need to convert each one to an integer and store each in separate integers. Then add them. See: http://msdn2.microsoft.co ...Show All
