Is there a setting I'm missing here which allows automatic setting of default column widths AND user resizing or is there another technique I must use when populating the DataGridView control?Īnother version of Miroslav Zadravec's code, but slightly more automated and universal: public Form1()įor (int i = 0 i < dataGridView1.Columns. Since the images you upload to the customer Z Gallery need to be 100kb or less in file size, most will need to be reduced in file size before uploading.s far as the length and width of the images you upload to the Z gallery, they will be automatically reduced in length and width so that the largest side is no longer than 800 pixels. The same result occurs when changing the grid's AutoSizeMode back to "Not Set" after loading the data. I've tried not setting the AutoSizeMode of all the columns which does allow resizing BUT doesn't set the initial size according to the data the cells contain. Now, you need to enter specific pixels ratio on both Horizontal and Vertical side fields. However, as I mentioned, once loaded I would like to allow the user to resize the columns to suit their own requirements - in setting these AutoSizeMode values for each column it appears the user is then unable to then resize those columns. On the Resize and Skew dialog box, choose Pixels. (I don't mind that when the user attempt to resize this column it springs back to a size that ensures the horizontal space is always used.) I am attempting to achieve this by setting the AutoSizeMode of each column to be DataGridViewAutoSizeColumnMode.AllCells except for one of the columns which I set to DataGridViewAutoSizeColumnMode.Fill in order to ensure the entire area of the grid is neatly filled with data. no unused (dark grey) areas down the right and sizes each column appropriately according to the data it contains, but also allows the user to resize any of the columns to their liking. My goal is to display a grid that neatly fills all available width with cells - i.e. Because this number is very unpractical to use, you. For example, if you have a photo that has 4,500 pixels on the horizontal side, and 3,000 on the vertical size it gives you a total of 13,500,000. If you have any questions or need further assistance, just drop us a line.I am populating a DataGridView control on a Windows Form (C# 2.0 not WPF). In order to calculate this resolution you just use the same formula you would use for the area of any rectangle multiply the length by the height. If you would like more options and variability in how you adjust your images, has more advanced tools. The most simple and fast online image "resizer" we found is, where you can choose from pre-set options quickly and easily. We have tested these options, and we think work pretty well! Therefore we have researched some simple options to help you quickly and easily be able to change your pictures online, without software, or having to purchase or download anything. Editing your image sizes isn't difficult, but not everybody has software, like Photoshop, to do so. The easiest way to do this is to first find aspect ratio of the image (from its pixel dimension) then map the width (in pixels) to 1 m. So whether your image is already "framed" the way you want it and you simply need to reduce the file size, or if you wish to perform more advanced editing, you need to do so before uploading your image to the Z Gallery. If you want to crop your image to remove some of the background and bring your Z to the forefront of the image, you will need to do so before uploading. So if your camera produces an image that is 3000 pixels wide, the Z Gallery software will reduce that image, as is, to 800 pixels wide. Since the images you upload to the customer Z Gallery need to be 100kb or less in file size, most will need to be reduced in file size before uploading.Īs far as the length and width of the images you upload to the Z gallery, they will be automatically reduced in length and width so that the largest side is no longer than 800 pixels. Having trouble uploading images? Most of today's digital cameras produce images with large file sizes that don't send very well over the internet.
