• EDV Gradl Problem with DateTimePicker and CustomFormat

  I defined an invalid date for my DateTimePicker (1/1/2007) and whenever this date is selected to be displayed on the DateTimePicker, it shows "Undefined date" instead. I did this using CustomFormat. The problem I have is that, whenever I select 1/1/2007 from the dropdown-calender, the calender doesn't close. The DateTimePicker shows "Undefined date" as desired, but the dropdown-calender doesn't disappear as it's supposed to do. I can still select different dates from the dropdown-calender but the DateTimePicker's value won't change anymore. I have to 'manually' close the drowdown-calender using the dropdown-button. When I reopen the calender to select a different date, it won't close again. Only after selecting a 'valid' date and m ...Show All

• JTB1 How can I Export Data From DataGrid to HTML file?

  Hi, May anybody help me I do not think there is a direct way to do this. But what you could do is to export underlying DataTable/DataSet into HTML. In this case you will loose formatting. You could loop through the records and construct HTML or you could persist data from the DataTable/DataSet into XML and transform into HTML using XSL. I do not think creating HTML will be hard to do for you. Code should be pretty simple. Basically you need to create HTML table. There is much choice - you write your own code, find some code on a Web or use some third-party component for it. With thanks for your answer, I have thought about this way before, I think this a the last way, i want to search for other ways if any. if i co ...Show All

• programmer01 DataGridViewImageColumn refresh issues

  Howdy ladies and gents, I was working on a .NET module today that creates a DataGridView at runtime, docked at the top of the parent form, and populates it with a mix of Image columns (containing Icons rather than Images), TextBox columns, and Link columns, and I noticed that when the form is redrawn, the icons aren't rendered properly. The masked space from the "transparent" portions of the Icons are being rendered with whatever data was present in the previous frame. I've set the background color of the cells individually, in addition to setting it in the template for new records. Possible tip: if I minimize and then restore the parent window, the "transparent" portions of the Icons are painted in the normal ...Show All
